篇1：名词性从句 教学总结(新课标版英语)
一、概况
1、定义：名词性从句是在主句中充当名词性成分的句子。
2、句中有哪些成分是名词性的：
句子成分一共七种：主谓宾定状补表。其中主谓宾是主要成分，定语状语是修饰性成分，而补语和表语是补充说明的成分。谓语是动词性的，主语和宾语是名词性的，定语是形容词性的，修饰句中的名词性成分；状语是副词性的，修饰句中的动词；补语可以是名词也可以是形容词，比如：They elected him president. (president n.作him的宾补). He makes me sick. (sick作me的宾补)； 表语是说明主语的性质内容状态的，可以是名词也可以是形容词，如：He is famous. (adj.) / He is a famous actor. (n.) 因此，句中的名词性成分有：主、宾、表、补。
3、从句的类别：上述四个名词性成分如用句子来充当，便成了名词性从句，它们分别为：主语从句、宾语从句、表语从句、补语从句。
4、名词性从句的连词：
1） 连接词：that, whether, if (只起连接作用，不充当从句中的任何成分)
2） 连接代词：what, whatever, who, whoever, whom, whomever, which, whichever, whose
3） 连接副词：when, where, how, why
二、主语从句
1、that/ what
如果把句子从中分开，分为主句和从句
That: 只有一个地方缺名词性成分，或两处都不缺时用that.
主句缺：（主、宾、表）I think that Shiyang will win the contest. (主句缺宾语)
That Shiyang win the first place makes us happy. (主句缺主语)
Our expectation is that Shiyang win the first place.
从句缺：（定语从句）That is the girl whom I mentioned to you before.
两处都不缺：（同位语从句）We all know the truth that the earth is round.
What: 两处都缺名词性成分：This is not what I want. （主句缺表语，从句缺宾语）
参见练习（14、15、19、42、46、47、54）再看以下例句：
1） Air is to man ______ water is to fish. (主句缺表语，从句也缺表语)
2） Electricity flows in wire _____ water runs in pipe. （主句从句都不缺成分）
A. like B. as C. that D. what
3) He was born in _____ is now called Xiangyang. （介词后面缺宾语）
A. where B. which C. that D. what
4) After _____ seemed a long time, he came back. （介词后面缺宾语）
A. what B. that C. it D. this
2、whether / that (主语从句中没有if)
会议是否开还没有决定：Whether the meeting will be held has not been decided.
会议是否开已经决定：That the meeting will be held has been decided.
*请记住：主语从句中的是否有两个，whether和that。未定，有选择的用whether; 确定事实用that。 主语从句中的是否不用if.
3、which / what
_____ team will win is unknown yet. _____ color will be chosen is unknown yet.
What +抽象概念 （color, information, news, whether, date, number）
Which+具体对象 (bag, hotel, boy)
但是有具体范围的时候都用which: What number is your lucky number?
Which number is your lucky number, 7 or 5?
4、形式主语
that 引导的主从放在句首是很少的， 只有为了强调或谓语较长时才这样安排。
如： The price will go up is certain. /
That she became an artist may have been due to her father’s influence.
大部分情况下都用it 来充当形式主语，主要有以下五种情况。
1） it is +n. +that ( a fact, a common knowledge, an honor, a pity, a good idea, a shame , no wonder)
2） it is +adj.+ that (natural, strange, obvious, clear, true, fortunate, possible, likely, unlikely)
3） it +vi.+ that ( seems, appears, happens, turns out, occurs to sb)
4） it is + v-ed + that ( said, reported, believed, known, expected, proved, announced )
it is universally accepted that （地球人都知道）
it can be concluded that
it must be admitted that
5） it doesn’t matter that / it matters that
6） 当主句是疑问句时，一定要用it 作形式主语
Is it true that he has won the game?
5、主语从句的主谓一致
1） How the boy climbed there ____ a puzzle.
2） What I like most and how I enjoy it ____me a lot of pleasure. ( bring/ brings)
3） Where and when the meeting will be held _____ been decided. ( haven’t / hasn’t )
4） What I like most ____ potatoes. ( is/ are)
5） What I like most _____ dancing. (is / are)
单个的主语从句作主语时，谓语动词用单数；两个或两个以上的主语从句作主语谓语动词用复数。有两个特例：① 单个主从，若表语是复数，则谓语动词用复数，如例4）；②有省略形式的主从，先恢复原形，看是一句还是两句，如例2）、3）。
三、宾语从句
1、时态：主句是过去时，从句要用和过去相关的时态，除非是普遍真理。
2、语序：宾从一定是陈述语序：I don’t know when he will come.
1） * I don’t know what’s the matter with him.
I don't know what the matter with him is. （×）
2）就宾从提问,特殊疑问词放句首。“你认为他什么时候会来？”
When do you think he will come? / Do you think when he will come? (×)
3、间接引语的用词细节
“上周三汤姆问我他明天是否去我家”: Last Wednesday Tom asked me whether he had to come to my home the next day. (× must / go / tomorrow)
4、三种宾语从句
1） 动词宾语：
2） 介词宾语
3） 形容词宾语：（表示心理活动的adj.: sure, afraid, happy, glad, excited）
`I’m glad that he has won the game.
5、第一人称＋主观判断的v.，后面的宾从中的否定要转移到主句
如：我认为你不对： I don’t think you are right.
6、if / whether
1） if 表示“是否”只能用在宾语从句中，whether可以用于所有的名词性从句. 在宾从中可通用：I wonder if / whether Mr Smith is his father.
2） 能跟or not连用表示选择的只有whether：I don’t know whether he has money or not.
3） 作介词宾语只能用whether: It depends on whether he will come back.
4） 在状语从句中，if 表示“如果”, 而 whether和or “whether……or”结构，表示“无论”。
7、谓语是doubt
1) 主句是肯定句，用whether 或if 来引导从句. If 持否定观点，whether持中立观点。
I doubt whether he will come. （不知是否会来）
I doubt if he will come. （估计他不来）
2) 主句是否定或疑问时，用that来引导从句
I don’t doubt that he will come.
Do you doubt that he will come?
8、并列宾从中第一个that 可以省略，第二个conj.不能省。
e.g. I know (that) he will come and that his brother will also come.
I want to know ______ he’ll come ______ his brother will also come.
A. whether …… or B. ……or
C. whether……or whether D. …… or whether
9、形式宾语：三种情况，一定要有形式宾语it
1) 在主句中有宾补：I think it possible that / I find it difficult that
2) 宾从作介词词组的宾语：I will see to it that (the door is closed) / take it for granted that
3) 固定结构： appreciate it that
We appreciate it that you read the letter for me.
10、宾从中的连接词that可以省略，但其它的连词不能省。
其它的连词可以看作就划线部分提问的特殊疑问词。
四、同位语从句
1、信号词：主句中有抽象名词news, information, idea, thought, fact, truth, hope, belief，suggestion, advice, assumption, plan, practice, proposal 等，从句用来说明名词所表示的具体内容。
e.g. We all know the truth that the earth is round.
2、同位语从句 VS 定语从句
There is a problem that the road needs to be broadened. (同)
There is a problem that we have to discuss. （定）
1）意义上：同位语从句的信号词都是有内涵的抽象名词，从句用来补充说明该名词的内容；定语从句的先行词可以是抽象名词，具体名词，还可以是代词，其作用为修饰限定。
2）结构上：同位语从句主句和从句结构完整，信号词在从句中不充当任何成分；而定语从句的从句缺成分，先行词在从句中可以充当一个成分。
3、同位语从句的连词不仅有that
I have no idea when he will come back.
The problem where can we raise the money is very important.
We will discuss the problem whether the sports meeting will be held on time.
I have no impression how he get there, maybe by subway.
I have no idea what happened to him.
五、表语从句
放在be, seem, appear, look，remain, happen, occur to等系动词后面，充当表语的句子。
The problem is whether we can make a good preparation in such a short time.
The fact remains that we are still behind many developed countries.
1、It seems / appears/ looks + that (as if / 连词省略)
It happens / occurs to sb + that ( as if)
2、表示原因的表语：The reason is that = It/ This/ That is because =This/ That is why
The reason he was late for the school is that he missed the early bus.
He missed the early bus. That is why he was late.
He was late for the school. That is because he missed the early bus.
Exercises:
1、A saying goes ____ no pain, no gain.
A. where B. when C. what D. that
2、The other day, my brother drove down the street at ____ I thought was a dangerous speed.
A. that B. what C. which D. as
3、Mary wrote an article on _____ the team had failed to win the game.

篇2：第十章 名词性从句 (新课标版高三英语下册教学论文)
第十章 名词性从句
在句子中起名词作用的句子叫名词从句 (Noun Clauses)。 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
高考重点要求：
1、掌握主语从句、宾语从句、同位语从句、表语从句的基本句型结构
2、弄清名词性从句的连词的用法和意义
3、根据句子语义确定使用何种从属连词
第一节 知识点概述
一、引导名词性从句的连接词
引导名词性从句的连接词可分为两类：
1. 名词性that从句，即以that为连接词的名词性从句。that只能起连接主句和从句的作用，不充当从句的任何成分，无词义。
2. 名词性wh-从句，即以wh-词连接的名词性从句。Wh-词包括：
连接代词：who, whom, whose, what, which, whoever, whatever, whichever
连接副词：when, where, how, why
连接词whether, if不充当句子的任何成分。
二、主语从句
1. 用作主语的从句叫主语从句。that从句作主语，that不能省略。
▲That he likes such kind of books is very interesting.他喜欢这种书是非常有趣的。
▲Whether he will be able to come remains a question. 他是否能够来仍然是一个问题。
▲What he is looking for is none of your business. 他在找什么与你无关。
2. 很多主语从句都可以用that作形式主语。例如：
It is very interesting that he likes such kind of books.
It remains a question whether he will be able to come.
3. It作形式主语主要包括以下几种类型和搭配关系：
1）It + be + adj. + 从句
It was obvious that the driver could not control his car.
2）It + be + n. + 从句
It is a pity that he missed the lecture.
3）It + be + 过去分词 + 从句
It is said that they have won the game.
4）It + be + vi. + 从句
It seems that something is wrong with the computer.
三、表语从句
表语从句在句中作表语，它位于主句的联系动词之后。that从句作表语，that不能省略。表语从句只用whether，不用if。
▲The problem is that smokers cannot go without smoking. 问题是抽烟的人不抽烟就会感到难受。
▲The question is whether it is worth doing. 问题是这是否值得做。
▲This is where he has worked for years. 这就是他多年工作的地方。
四、宾语从句
宾语从句在句中作宾语，引导宾语从句的that可以省略。whether和if可互换，但介词宾语或有or not时，用whether.
▲They know that the habit may kill them. 他们知道这个习惯能使他们致死。
▲They doubt whether or not Jack is a good student. 他们怀疑Jack是否是一个好学生。
▲They wanted to see which shops offered the best advice and service. 他们想了解哪家店提出的建议和提供的服务最好。
五、同位语从句
同位语从句中先行词不充当从句成分，从句是用来解释先行词的内容。That从句作同位语，that不能省略。
▲Word came that our football team had won the match. 消息传来，我们的足球队赢了比赛。
▲May I ask a question when the meeting will be held? 我能否问个问题，会议什么时候举行？
第二节 实战演练
一、复习时需注意的要点
1. 由从属连词that引导的从句叫做名词性that-从句。 That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。名词性that-从句在句中能充当主语、宾语、表语、同位语
2. 主句和从句要保持时态上的一致性，从句还要保持陈述句语序。
3. 当从句是由选择问句转化而成时，一定要用whether构成whether...or结构。
4. That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：
It is quite clear that the whole project is doomed to failure.很清楚，整个计划注定要失败。
It's a pity that you should have to leave. 你非走不可真是件憾事。
用it作形式主语的that-从句有以下四种不同的搭配关系：
a. It + be + adj. + that从句
It is necessary that… 有必要……
It is important that… 重要的是……
It is obvious that… 很明显……
b. It + be + 过去分词 + that从句
It is believed that… 人们相信……
It is known to all that… 从所周知……
It has been decided that… 已决定……
c. It + be + n. + that从句 It is common knowledge that… ……是常识
It is a surprise that… 令人惊奇的是……
It is a fact that… 事实是……
d. It + be + vi. + that从句
It appears that…似乎……
It happens that…碰巧……
It occurred to me that… 我突然想起……
5. 选择性疑问从句
选择性疑问从句由关联词whether…or或whether…or not构成，例如：
Please tell me whether they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。
I don't care whether you like the plan or not.我不在乎你是否喜欢该计划。
二、历届高考试题分析
例1、_____ in the regulations that you should not tell other people the password of your e-mail account.
A. What is required B. What requires
C. It is required D. It requires
答案为C
【解析】 本句的结构为It is +动词的过去分词+that 引导主语从句。经常用于这种结构的动词还有say, report, think, hope, expect, consider, suggest等。
例2、There is a new problem involved in the popularity of private cars _________ road conditions need_________.
A. that ...to be improved B. which...to be improved
C. where ...improving D .when...improving
答案为A。
【解析】 考查同位语从句。因为先行词在从句中不作任何成份，因此用关系词that，故B、C、D均不正确。对于第2个空格，need既可作实义动词，又可作情态动词。作实义动词时后跟动词不定式，即need to do sth.，另外 road conditions与improve之间是被动关系，因此是need to be improved(need to be done=need doing)。译文：私家车受欢迎所涉及到的新问题是道路状况需要改善。
例3、_________made the school proud was_________ more than 90% of the students had been admitted to key universities.
A. What; because B. What; that C. That; what D.That; because
答案为B。
【解析】 what引导主语从句，在主语从句中作主语；that引导表语从句，在表语从句中起连接作用。
例4、There's a feeling in me _______we'll never know what a UFO is-not ever.
A. that B. which C. of which D. what
答案为A。
【解析】 同位语从句that we'll never know what a UFO is-not ever作a feeling的同位语，解释a feeling的具体内容。that连接同位语从句时，只起连接作用不作从句的任何成分。译文：我有一个这样的感觉，我们不会知道什么是UFO--永远不会。
例5、Perseverance is a kind of quality-and that's _______ it takes to do anything well.
A. what B. that C. which D. why
答案为A。
【解析】 这是一个表语从句，what在表语从句中作takes的宾语，构成“It takes sth. to do sth.”的句型。译文：坚定不移是一种品质--坚定不移使人们做好任何事情。
例6、When you answer questions in a job interview, please remember the golden rule: Always give the monkey exactly _______he wants.
A. what B. which C. when D. that
答案为A。
【解析】 这是一个宾语从句，wants后面缺少宾语，所以要填写what。Always give the monkey exactly what he wants是一句谚语，意思是“永远不折不扣地给予对方他想要的东西。”译文：当你在找工作面试回答问题时，请记住这条黄金定律：永远不折不扣地给予对方他想要的东西。
例7、Information has been put forward ________ more middle school graduates will be admitted into universities.
A. while B. that C. when D. as
答案为B。
【解析】 这是一个同位语从句。that引导从句作information的同位语，解释information的具体内容。注意：that和what引导名词性从句(主语、宾语、表语和同位语从句)的区别：that引导名词性从句，只起引导作用，在从句中不作成分。that引导宾语从句时，that可省略，而在其他三个从句中，that虽不作成份，一般也不省略；what在这四个名词从句中一定作成分，作主语、宾语、表语或补语。译文：有消息说，更多的中学毕业生将进入大学。
例8、What the doctors really doubt is ________ my mother will recover from the serious disease soon.
A. when B. how C. whether D. why
答案选C。
【解析】 这是一个表语从句。根据doubt一词可知，所怀疑的应是是否能治好病，所以要填whether。这句话的意思是“医生真的怀疑我妈妈是否能从重病中很快康复。”
例9、-I drove to Zhuhai for the air show last week.
-Is that ________ you had a few days off?
A. why B. when C. what D. where
答案为A。
【解析】 这是一个why引导的表语从句，表示原因。这句话的意思是“这就是你为什么离开几天的原因吗?”
例10、________she couldn't understand was ________fewer and fewer students showed interest in her lessons.
A. What...why B. That...what C. What...because D. Why...that
答案选A。
【解析】 主语从句she couldn't understand缺少宾语，要用What引导。表语从句fewer and fewer students showed interest in her lessons是一个完整的句子，要用why引导，意思是“为什么越来越少的学生对她的课感兴趣”。

英语名词性从句课件
【考情分析】
名词性从句是历年高考的重点和难点也是热点。名词性从句相当于名词，可用作主句的主语、表语、宾语和同位语。因此，名词性从句分为主语从句、表语从句、宾语从句和同位从句。引导名词性从句的连接词有:连接代词:who, whose, whom, what, which，有词义，在从句中担任成分，如主语、表语、宾语、或定语等;连接副词:when, where, why, how，有词义，在从句中担任成分，作状语;连接词:that, whether, if, as if，if (whether), as if虽有词义，但在从句中不担任成分;that 无词义，在从句中不担任成分，有时可省略。
今后对名词性从句的考查仍将集中在关联词的选用上，特别石堆what引导的名词性从句的考查。名词性从句与其他从句的混合考查将在今后高考中占据一席之地。易混句型的辨析，比如it作形式主语，主语从句后置的句型与强调句型的辨析将仍作为高考考查的重点。
【知识点归纳】
名词性从句的用法
在句子中起名词作用的句子叫名词从句 (Noun Clauses)。 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
一、引导名词性从句的连接词
引导名词性从句的连接词可分为三类:连词:that(无任何词意);whether, if(均表示“是否”表明从句内容的不确定性);as if ,as though(均表示“好像”，“似乎”)。
以上在从句中均不充当任何成分
连接代词:what, whatever, who, whoever, whom, whose, which. Whichever, whomever
连接副词:when, where, how, why
不可省略的连词:
1. 介词后的连词
2. 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.
We heard the news that our team had won.
比较:
Whether与if 均为“是否”的意思。 但在下列情况下，whether 不能被if 取代:
1. Whether引导主语从句并在句首;
2. 引导表语从句
3. Whether从句作介词宾语;
4. 从句后有“or not”
Whether he will come is not clear.
大部分连接词引导的主语从句都可以置于句末，用 it充当形式主语。
It is not important who will go.
It is still unknown which team will win the match.
二、具体分类
1.主语从句
作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如:
What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。
【典例1】(·上海卷)It is immediately clear ____ the financial crisis will soon be over.
A. since B. what C. when D. whether
【答案】D
【解析】考查主语从句的用法。该句的意思时:经济危机是否会很快结束是很明显的事情。“是否”用whether表示，不能选when是因为从句中由soon这一实践状语。
【典例2】(·山东卷)_____ was most important to her, she told me, was her family.
A. It B. This C. What D. As
【答案】C
【解析】she told me是插入语，可删除。what引导主语从句，在从句中充当主语。
有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下:
(1)It + be + 名词 + that从句
(2)It + be + 形容词 + that从句
(3)It + be + 动词的过去分词 + that从句
(4)It + 不及物动词 + that 从句
另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有:
It is necessary (important, natural, strange, etc.) that …
It is a pity (a shame, no wonder, etc.) that…
It is suggested (requested, proposed, desired, etc.) that…
【典例】(2009·天津卷)It is obvious to the students ______ they should get well prepared for their future.
A. as B. which C. whether D. that
【答案】D
【解析】考查名词性从句。本空格处应是一个主语从句的引导词，因该主语从句不缺成分，且句意完整，故应用不作任何成分的连词that。
2.宾语从句
名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。
(1) 由连接词that引导的宾语从句
由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。例如:
He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。
We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。
注意:在demand，order，suggest，decide，insist，desire，request，command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“(should)+ 动词原形”。例如:
I insist that she (should) do her work alone. 我坚持要她自己工作。
The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。
(2)用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。例如:
I want to know what he has told you. 我想知道他告诉了你什么。
She always thinks of how she can work well. 她总是在想怎样能把工作做好。
She will give whoever needs help a warm support. 凡需要帮助的人，她都会给予热情的支持。
【典例1】(2008·北京卷)The companies are working together to create _______ they hope will be the best means of transport in the 21st century.
A. which B. that C. what D. who
【答案】C
【解析】create后为宾语从句，从句中they hope是插入语，可删除。因为从句中缺少主语，所以用what引导该从句。
【典例2】(2009· 全国卷Ⅰ) Could I speak to is in charge of International Sales please?
A. who B. what C. whoever D. whatever
【答案】C
【解析】 考查名词性从句。题干中介词to后面为宾语从句，从句中缺少主语，因此填whoever。
(3)用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if:
a. 引导主语从句并在句首时;b. 引导表语从句时;c . 引导从句作介词宾语时;d. 从句后有“or not”时;e. 后接动词不定式时。例如:
Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。
The question is whether she should have a low opinion of the test?
Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。
I wonder whether he will come or not. 我想知道他来还是不来。
Can you tell me whether to go or to stay? 你能否告诉我是去还是留?
(4)注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用
不同时态。例如:
he studies English every day. (从句用一般现在时)
he studied English last term. (从句用一般过去时)
I know (that) he will study English next year. (从句用一般将来时)
he has studied English since . (从句用现在完成时)
当主句动词是过去时态(could, would除外)，从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等;当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如:
The teacher told us that Tom had left us for America.
(5)think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如:
We don’t think you are here. 我们认为你不在这。
I don’t believe he will do so. 我相信他不会这样做。
3.表语从句
在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。其基本结构为:主语 + 系动词 + that从句。例如:
The fact is that we have lost the game. 事实是我们已经输了这场比赛。
That’s just what I want. 这正是我想要的。
This is where our problem lies. 这就是我们的问题所在。
That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。
It looks as if it is going to rain. 看上去天要下雨了。
需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如:
The reason why he was late was that he missed the train by one minute this morning .
【提拨】whether 可引导表语从句，但与之同义的if却通常不用于引导表语从句。
【典例1】 (2009·山东卷)The little girl who got lost decided to remain ________she was and wait tor her mother.
A. where B. what C. how D. who
【答案】A
【解析】remain是系动词，后加表语从句，由句意可知，从句缺地点状语，所以选A。
【典例2】(2008·天津卷)The last time we had grat fun was _______ we were visiting the Water Park.
A. where B. how C. when D. why
【答案】C
【解析】was后为表语从句，此处when与the last time相呼应，根据句意可排除其他选项。
4. 同位语从句
同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice，demand，doubt，fact，hope，idea，information，message，news，order，problem，promise，question，request，suggestion，truth，wish，word等。例如:
The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。
I have no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
【典例】(2009· 重庆卷) We should consider the students’ request ________ the school library provide more books on popular science.
A. that B. when C. which D. where
【答案】A
【解析】考查名词性从句。根据题意知，空格处是同位语从句的引导词，修饰中心名词request，且在句子中不充当成分，故用that。这句话的意思是我们应该考虑学生的这个要求，即学校图书馆应该多提供一些大众科学方面的书籍。
三、对比与用法
1.同位语从句和定语从句的区别:
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略; that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句:
I had no idea that you were here.(that引导同位语从句，不能省略)
Have you got the idea(that)this book gives you of life in ancient Greece?(that引导定语从句，作宾语，可以省略)
2.that-从句作主语通常用it作先行词，而将that-从句置于句末。
用it作形式主语的that-从句有以下四种不同的搭配关系:
a. It + be +形容词+ that-从句
It is necessary that… 有必要……
It is important that… 重要的是……
It is obvious that… 很明显……
b. It + be + -ed 分词+ that-从句
It is believed that… 人们相信……
It is known to all that… 从所周知……
It has been decided that… 已决定……
c. It + be +名词+ that-从句
It is common knowledge that… ……是常识
It is a surprise that… 令人惊奇的是……
It is a fact that… 事实是……
d. It +不及物动词+ that-分句
It appears that… 似乎……
It happens that… 碰巧……
It occurred to me that… 我突然想起……
It is quite clear that the whole project is doomed to failure.
很清楚，整个计划注定要失败。
It's a pity that you should have to leave.
你非走不可真是件憾事。
3.否定转移
(1) 将think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的'否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
I don't think I know you. 我想我并不认识你。
I don' t believe he will come. 我相信他不回来。
注意:若谓语动词为hope,宾语从句中的否定词不能转移。
I hope you weren't ill. 我想你没有生病吧。
(2)将seem, appear 等后的从句的否定转移到前面。
It doesn't seem that they know where to go.
看来他们不知道往哪去。
It doesn't appear that we'll have a sunny day tomorrow.
看来我们明天不会碰上好天气。
【备考策略】
考生对于名词性从句的复习和应试关键要把握每个引导词的意义，因为在对于名词性从句的考查中，引导词在句子中都起作用，有意义，因此在分析句子结构，对比辨别名词性从句、状语从句、强调句式后，最后还是要选择引导词;另外还要注意以下几点:
1.what 引导词的考查，尤其位于介词后引导的宾语从句以及引导名词性从句时的双重作用。
2.Whether和if 的区别，尤其注意他们的不同之处。
3.名词性从句和其它从句的兼容结构测试。
4.句子语序和时态。
具体说:
1.掌握名词性从句的分类功能
名词性从句根据其在主句的功能作用又可分为主语从句、宾语从句、表语从句和同位语从句。
(1) 若从句在句中作主语为主语从句
(2) 若从句在句中作宾语为宾语从句
(3)若从句在句中作表语为表语从句
(4) 若从句在句中作同位语为同位语从句
2.掌握连词的含义及分类
绝大多数名词性从句的连词都有其实在意义，称为有义连词，如what表“……的内容”，when表“……的时间”，where表“……的地点”，why表“……的原因”，how表“如何;怎样”，who表“谁”，if, whether表“是否”;没有实在意义的连词叫无义连词，无义连词只有that一个。
3.掌握名词性从句的语序
名词性从句用陈述语序。
4.掌握名词性从句和其它从句之间的关系
有些连词除引导名词性从句外还可引导其它从句，应掌握它们之间的关系。
(1) if ,whether表“是否”时引导名词性从句;if表“如果”时引导条件状语从句;whether表“无论是否;不管是否”时引导让步状语从句。
(2) when表“……的时间”，where表“……的地方”时引导名词从句;when表“当……的时候”引导时间状语从句，where表“……的地方”，且修饰行为动词时，引导地点状语从句;when, where从句作定语修饰先行词时引导定语从句。
【专题突破】
高考中考查名词性从句时，经常考查连接词的选用。解题时应先判断从句的类型，然后判断从句是否缺少成分以及意义是否完整，最后根据引导名词性从句的连词的特点确定特定的连接词。要求学生在做题中要注意如下几点:
1.分析结构，辨析名词性从句和状语从句;
2.理解句意，正确区别引导词;
3.按照句意，出现那个引导词意思，便选择那个引导词。

【参考答案及解析】
1. C 句意:我脑海中突然出现一个温情的念头，用我的零花钱给妈妈买些鲜花作为她的生日礼物。本题考察名词性从句用法。I might use the pocket money to buy some flowers for my mother’s birthday .做A warm thought 的同位语从句。中间被suddenly came to me隔开，增加了试题难度。此外，部分考生由于对同位语从句和定语从句不分，故错选D为答案。
2. D 表语从句中缺did的宾语。
3. A “_______is still a wasteland now .”做介词in的宾语从句，从句中缺主语句意为:政府已经宣布一座现代化的城市将在这片现在仍是废墟的地方建成。
4. A“_______Liu Xiang had failed to compete in the event.”做介词on的宾语，宾语从句中不缺主干，故排除B和C。另外that不引导介词的宾语从句(固定搭配除外)，所以排除D。
5. B “_______is described as one of the most beautiful islands .”宾语从句，从句中缺少主语，
6. B whoever在宾语从句中做主语，部分学生，因为只看到介词to，误认为要添whomever做介词的宾语。
7. B “_______it takes to keep a nation highly competitive.”做表语从句，从句中缺少takes的宾语，构成 it takes sth to do sth 结构。
8. A本题句子结构比较复杂，“_______ a nation loses in times of disaster will be made up for by her progress”做a truth的同位语从句，同位语从句中_______ a nation loses in times of disaster为主语从句。本句共有两个从句，故有两个引导词。句意为“中华民族的经验证明了一个真理，即，一个民族在灾难中失去的，必将从民族的进步中得到补偿。
9. C “_______has recently been done to provide more buses for the people”在句中做让步状语,而D. Though what错误, 因为, 一个单一的从句不能用两个连词引导.句意: 尽管在为人们提供更多公交车这件事上, 投入了很多, 但是公交工具的缺乏, 仍然是个问题.
10.B “_______is certain”在句中做主语,主语从句缺少一个主语,需要用What; “_______prevention is more important than treatment .”系表语从句,句意与结构完整,只有that,可以这样用。
11.A“_______ they lost the game.”在句子中做the fact 的同位语从句,从句意思结构完整,结构完整。
12. C先将句子结构理清楚，it is _______that has made him _______he is today 就可以判断，第一个空是考察强调句型的特殊疑问形式;第二个空则是表语从句，表语从句中缺少he is的表语。句意:病人好多了，是什么使得他成为现在这个样子。
13. A考生误以为是地点状语从句，误选C.where。而reached是及物动词，后边接的是宾语从句，宾语从句除去插入语they thought，应该缺主语。
14.B 考察同位语从句，表达A plan的具体内容，has been put forward将名词与从句隔开，加大了难度。
15.C 主要测试主语从句。分析句子结构可知:句子属于形式主语格式;另外主句中缺少主语。双重作用的引导词只能是what。例如:It is still doubtful what he said at the meeting yesterday。昨天他在会上说的话仍然值得怀疑。
16.C 名词性从句的引导词。句意为:她对我们来说是非常宝贵，我们已经准备好做一切来拯救她的生命。
17.D 此处从句作介词to的宾语，是名词性从句，引导词作从句的主语，指人，意思是:无论是谁，选D。
18.C 考查名词性从句，介词from后除了接代词或名词作宾语外，还可接介词短语或副词短语作宾语;由后面“I was born”可以推测from后面可以指时间，也可以指地点，再由所给的选项可得出答案。
19.D 考查名词性从句。宾语从句中缺少主语，因此选what。
20. B考查同位语从句。此处是由what引导的同位语从句，表示“你有没有可能来机场接我?”。所以选B项。
篇4：考研英语名词性从句语法
语法在考研大纲中并做没有明确的说明，容易被忽视，但无论是阅读、完型填空，还是翻译，甚至写作，对语法的考查又是无处不在的。在完型填空中，严格地说，语法是可以作为考题出现的，例如选择连词或代词的题，我们就可以把它们当作语法的题型来解决。
这里我们先总结一下能够涉及到的从句。在考研英语中，总共有三大类型从句，即名词性从句，定语从句和状语。我们这里先看一下名词性从句。名词性从句就是指在句子中起名词作用的从句，其功能相当于名词词组，在复合句中可以担任主语、表语、同位语、介词宾语等。根据它在剧中不同的语法功能，名词性从句可以分为主语从句，宾语从句，表语从句和同位语从句。
1、主语从句
主语从句在复合句中充当主语，为了避免头重脚轻的情况，平衡句子结构，一般用it作形式主语代替处于从句，把主语从句置于句尾。在完型填空中，对主语从句的考查以形式主语it为主。例如：It did not matter what was done in the experiment。it 作形式主语，关系代词what引导的从句是句子真正的主语。句子含义为：实验中做什么无关紧要。
2、宾语从句
宾语从句在复合句中充当宾语，可以作动词的宾语、介词的宾语。也可以用于动词+it+that 结构，由it 作形式宾语。例如：That kind of activity makes it less likely that the court’s decisions will be accepted as impartial judgments. () 在这句话中，it作形式宾语，而真正的宾语是that 引导的宾语从句。注意在这样的结构中，that是不可省略的。句子的含义为：这种行为使得法院的判决不太可能被视作公正无私。
3、表语从句
标语从句放在系动词后，充当复合句中的表语，一般结构是主语+连系动词+表语从句。引导表语从句的that通常可以省略。可以接表语从句的连系动词有be, look,remain等。另外，常用的结构还有the reason…that(不用because)和it is because…例如：Part of the problem is that the justices are not bound by an ethics code. (2012)这句话中，that从句作连系动词is的表语，说明“问题是什么”。句子的含义为：部分为题在于法官不受道德规范的制约。
4、同位语从句
同位语从句在完型填空中出现的次数很多，广大考生要引起注意。同位语从句用于对名词作进一步解释，说明名词的具体内容。能接同位语从句的应为表示抽象概念的名词，如：idea, belief, fact等。同位语从句一般由that 引导，但也可以用关系代词(what, which, who)、关系副词(when, where, why, how)或者whether …引导。例如：Contrary to the descriptions on record, no systematic evidence was found that levels of productivity were related to changes in lighting. (2010) 在这句话中，句子的主干为no systematic evidence was found，句首Contrary to 作状语， that引导的同位语从句置于谓语部分后。句子的含义为：与所记载的描述相反，没有系统的证据证明生产效率与照明的变化之间存在关联。
以上，我们梳理了一下名词性从句的四种从句。广大考生在复习的时候，要做好区分。祝各位同学复习顺利，考试成功。

篇6：学习总结：高考英语名词性从句冲刺
学习总结：高考英语名词性从句冲刺
Who / whoever, what / whatever等的用法区别
一般说来，what/who等含特指意义，而whatever/whoever等含泛指意义，意为“无论什么/无论谁”，
It is generally considered unwise to give a child ____ he or she wants.
A. however B. whatever C. whichever D. whenever
解析：答案是B，whatever引导一个宾语从句，并且作wants的宾语。这里的whatever不能改成what，因为题意想表达的显然是“无论孩子要什么就给他/她什么事不明智的”，具有泛指的概念。同时要注意，这里whatever也不能改用no matter what，因为后者只能引导状语从句。比较下例：
I can’t remember at the moment who has said the words. (这里的who表特定的某人)
Where, when, why等连接副词引导的名词性从句
Where, when, why等连接副词也可以引导名词性从句，使用的关键是：这个词必须符合句子的逻辑要求。
—I drove to Zhuhai for the air show last week.
—Is that ____ you had a few days off?
A. why B. when C. that D. where
解析：答案是A，why引导的从句作表语，同时why在从句中作原因状语。这里之所以选why，而不是when或 where等，唯一的依据便是句子的逻辑含义，及语境。
“介词+who(m)引导的宾语从句”与“介词+ whom”引导的定语从句的区别
介词后面的引导词用主格还是宾格，决定于它在宾语从句中作主语还是宾语。
It was a matter of ____ would take the position.
A. who B. whoever C. whom D. whomever
解析：答案是A。这是一个含宾语从句的复合句，作介词of宾语的，是后面的整个句子，而不是宾语从句的引导词，由于这里引导词在从句中作主语，所以要用主格who(作宾语时自然要用whom)，
名词性从句中有插入成分时
此时应注意两点：一是从句仍然不倒装，而在插入成分上倒装;二是要注意主语的主格和宾格的选择。
____ you have seen both fighters, ____ will win?
A. Since; do you think who B. As; who you think
C. When; whoever D. Since; who do you think
解析：根据上面的讲解，不难知道答案是D。其中do you think是插入成分，其余部分是宾语从句，作think的宾语;由于引导词在从句中作主语，所以要用主格who(不用whom)。
引导词that的省略
引导宾语从句时，that通常可以省略，但引导主语、表语和同位语从句时，that不能省。例如：
China’s success in manned-spacecraft travel shows ____ our country has become one of the greatest powers in space research.
A. what B. which C. 不填 D. it that
解析：该句中的.从句作shows的宾语，是宾语从句，又因为从句中不缺主、宾语，所以只能用that引导;又因引导宾语从句时that可以省略，所以答案是C。
同位语从句引导词where, when的用法特点
说明先行词内容的同位语从句的引导词where, when与被说明的名词在概念上不一致。但引导定语从句的引导词却必须保持一致。试比较：
1.Then arose the question ____ we were to get so much money.
2.This the house ____ the great man Mao Zedong was born 110 years ago.
A. where B. that C. about which D. in which
解析：答案分别是1.A 2.A/D。先行词与where, when概念一致时，是定语从句，2题中的house与where同表地点，且这个关系副词where或when可以用“介词+which”的形式代替，所以答案A 和D都可以引导。1题中的question与where不表同一概念，可见是同位语从句，所以where不能改用“介词+which”的形式。
篇7：英语中名词性表语从句介绍
名词性从句
英语语法中的名词性从句，是一个在句子中起名词(属性)作用的句子。名词性从句的功能相当于名词词组， 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等。所以，根据它在句中不同的英语语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
表语从句
通常位于谓语和系动词之后，以从属连接词开头。
•连接表语从句的连词
纯连词：that, whether
连接副词：when, where, how, why
连接代词：what
My idea is that we meet in the bookstore.
我的想法是我们在书店里见面。
Her doubt is whether you really mean it.
她怀疑的是你是否真的有意。
This is where my grandparents lived.
这就是祖父母曾经生活过的地方。
=This is the place wheremy grandparents lived.
That was how she reported to her parents.
那就是她向父母汇报的方式。
= That was the way how she reported to her parents.
That is why we all side with him.
那就是我们都同他站在一边的原因。
= That is the reason why we all side with him.
Is this what Jim gave you?
这就是杰姆给你的东西。
= Is this the thing what Jim gave you?
That is what your daughter brought back.
那就是你女儿带回来的东西。

篇8：定语从句（形容词性从句） (新课标版高三英语下册教学论文)
定语从句（形容词性从句）
在句中修饰名词或代词的从句，因其修饰作用相当于形容词，故称形容词性从句，即通常所说的定语从句。被定语从句修饰的词叫先行词。引导定语从句的有：
1）关系代词： 先行词为人：who, whom, that, whose
先行词为物：which, that, whose
2）关系副词：when, where, why
注意： 关系词起三个作用：①连接先行词和定于从句②替代先行词③在从句中担任成分
what不能引导定语从句。定语从句一般紧跟在先行词后，但有时也被一个短语隔开。
例如：I was the only person in my office who was invited.
1. 关系代词和关系副词的一般用法
1) 关系代词在从句中充当主语、宾语或表语等成分，关系代词充当宾语、表语时可以省略：
Here’s a fellow who just walks into a bank and helps himself to so much money. （作主语）
He is no longer the man (that) he used to be. （作表语）
This is the book（that/which）I referred to in my talk. (作宾语)
whose在定语从句中置于名词之前，充当定语，既可指人，又可指物。
whose +n.= the +n.+ of which/whom。例如：
Please pass me the dictionary whose cover is black. （指物）
=Please pass me the dictionary the cover of which is black.
The doctor, whose name was Johnson, lived in a small town in the north of England. （指人）
=The doctor, the name of whom was Johnson, lived in a small town in the north of England.
2) 关系副词when, where, why在从句中充当状语，分别可表时间、地点或原因。
I will never forget the day when I first came to Beijing.
This is the house where Lu Xun once lived.
I know the reason why he came late.
注：先行词是the way时，其后的定语从句关系词有三种，例如：
I like the way in which / (that)the teacher gives his lessons.
从句缺少的是主语、宾语还是状语是确定用关系代词还是关系副词的关键。也就是说要看先行词在定语从句中担任什么成分
试比较：
I will never forget the day (which/that) I spent in Hongkong.
( spent是及物动词，后缺宾语，因此用关系代词或省略 )
I will never forget the day when/on which Hongkong returned to its motherland.
（ 从句主谓宾结构完整，缺状语，因此用关系副词或介词加关系代词 ）
The reason （that/which）he gave for not coming to school yesterday is unbelievable.
( gave是及物动词，后缺宾语，因此用关系代词或省略 )
The reason why he didn’t come to school yesterday is unbelievable.
（ 从句主谓宾结构完整，缺状语，因此用关系副词或介词加关系代词 ）
2．限制性定语从句与非限制性定语从句
限制性定语从句对先行词起限定作用，去掉后主句意义就变得不明确，它与主句之间没有逗号分隔。例如：
This is a shop that sells personal computers.
The watch that I bought yesterday works well.
非限制性定语从句与主句之间的关系相对松散一些，它对先行词起补充说明作用，去掉后不影响主句意义。因此，一些具有区别意义的专有名词及一些表示“唯一”概念的人或物后面常用此类从句。这类从句与主句之间有逗号隔开。例如：
We are all proud of the Great Wall, which is one of the man-made wonders of the world.
My father, who is a doctor, often encourages me to work hard.
注意：在非限制性定语从句中作宾语的关系代词不能省去。
一种特殊的非限制性定语从句
在非限制性定语从句中，有时根据句子意思，常把some, any, none, all, both, several, many, most, neither, either等词、分数或百分比与of whom或of which连用。
He has five children, two of whom are abroad.
(比较：He has five children, and two of them are abroad.)
We have tested three hundred types of boots, none of which is/are completely waterproof.
(比较：We have tested three hundred types of boots, but none of them is/are completely waterproof.)
3．介词+关系代词的用法
关系代词紧跟在介词后面时，不能用that，也不能省略，常用which或whom。
介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。例如：
The man (who/whom/that) I talked about at the meeting is from Beijing University.
=The man about whom I talked at the meeting is from Beijing University.
The palace (which/that) I often pay a visit to was built in the 17th century.
=The palace to which I often pay a visit was built in the 17th century.
但遇固定词组时，介词一般紧跟词组主体，不作前置。如：
Is this the book (which/that) you are looking for? ( 这里介词for一般不提前，因为look for是固定词组，意为“寻找”，介词for若被提前，单个的look意为“看”，句意不符。)
介词也可结合句意、根据先行词确定，此时介词以前置为佳。
Last night I had a dream in which I became a Nobel Prize winner.
The girl with whom I went to the concert yesterday is my sister.
I need a pen with which I can write a letter.
I need a piece of paper on which I can write a letter.
4．关系代词的一些特定用法：that与which；that与who
1）指物时，关系代词that和which一般情况下可换用，但以下几种情况下一般用that，不用which：
①先行词是all, everything, something, anything, nothing, none, few, little, much等不定代词；或是先行词被all, every, some, any, no, few, little等修饰时：
Is there anything (that) I can do for you in town?
I have read all the books (that) you gave me.
注：当something确指某物或某事时，用that或which都可以，如：
There is something that/which keeps worrying me. “有一件事一直令我不安。”
②先行词被形容词最高级或有序数词the first, the second…, the last修饰时：
This is the best film (that) I have ever seen.
The first place (that) we’ll visit is the Great Wall.
③先行词被the only，the very修饰时：
The only thing that matters is to find our way home.
This is the very book (that) I’ve been looking for.
④先行词既有人又有物时：
They talked about the persons and things (that) they remembered in the school.
⑤当主句是由who或which引导的特殊问句时，为避免重复，定语从句中常用that：
Who is the man that is standing by the door?
Who that has common sense will do such a thing?
Which is the dictionary (that) you bought yesterday?
Which that you bought just now is for me?
⑥两个定语从句，一个用which一个用that
Edison built up a factory which produced things that had never been seen before.
2)用which不用that：
①介词后②非限制性定于从句中③两个定语从句，一个用that一个用which
3)当先行词是anyone, those, he, she等代词表“人”时，一般用who而不用that：
Anyone who wants a ticket please sign your name here.
Those who want to go to the English party must be at the school gate by 7:30 p.m.
He who doesn’t reach the Great Wall is not a true man.
但当关系代词在定语从句中作表语时，通常用that而不用who：
He is no longer the man that he used to be.
5．定语从句中的as及其与which的异同
1）as引导的限制性定语从句：
当先行词有the same, such, as, so修饰时，要用as代替who(m), which, that来引导定语从句：
I’d like to have the same books as are used in your school.
He is not such a person as I expected.
He will marry as pretty a girl as he can find.
注意区别：
It was such a good film that I saw it yesterday.
Don’t talk about such things as you don’t understand.
Here is so big a stone that no one can move it.
Here is so big a stone as no one can move.
His speech was so clear that we could understand well.
He knows as many people as are present.
Yesterday she bought the same book as I have.
He is the same man that gave us a talk last year.
2）as引导的非限制性定语从句与which引导的非限制性定语从句的异同
which和as都可以指代主句中的一部分或整个句子的内容，有时可以互换：
Our team lost the game, as/which was reported in the newspaper.
She was terrified, as/which I could see from her eyes.
区别：①as引导的非限制性定语从句可以放在主句前面、插在主句中间或放在主句末尾；而which引导的非限制性定语从句只能放在主句后面。例如：
As anybody can see, the elephant is like a snake.
=The elephant, as anybody can see, is like a snake.
=The elephant is like a snake, as anybody can see.
Mary was late again, which made the teacher angry.
②as引导的从句有“正如”、“正像”之意，常用句型有：
as we all know, as is known to all, as everybody can see, as is expected等。
例如：As we all know, paper was first made in China.
Which引导的从句是对主句的评论或主句造成的结果。Which= and this
He failed in the experiment, which was unexpected.
He stole the money, which was disgraceful.
6. He is one of the workers who live in the factory.
He is the only one of the workers who has been there.
典型例题分析
1．All ____ is needed is a supply of oil. ( ’89 )
A. the thing B. that C. what D. which
解析：本题考查引导定语从句的关系词，what只能用于名词性从句，因此A/D可以排除，又因先行词为不定代词all，所以答案为B。
2．He paid the boys $10 for washing ten windows, most of ____ hadn’t been cleaned for at least a year. ( ’90 )
A. these B. those C. that D. which
解析：本题考察非限制性定语从句。从句子结构上看，两句之间用的是逗号，无连词连接，故确定为从属句，介词后面的关系代词代物，只能用which，答案为D。
3．In the dark street, there wasn’t a single person ____ she could turn for help. ( ’92 )
A. that B. who C. from whom D. to whom
解析：本题考查定语从句中介词加关系代词的用法。根据句意“向某人求助”是turn to sb. for help，其中介词to可提前，故答案为D。本句也可以如下表达：In the dark street, there wasn’t a single person (who/whom/that) she could turn to for help.)
4．After living in Paris for fifty years, he returned to the small town ____ he grew up as a child.
A. which B. where C. that D. when ( ’96 )
解析：本题考查关系代词和关系副词的用法，从句he grew up as a child不缺主语或宾语，排除关系代词which和that，又因先行词是表地点的，故答案为A。
5．Dorothy was always speaking highly of her role in the play, ____, of course, made the others unhappy. ( )
A. who B. which C. this D. what
解析：本题考查非限制性定语从句指代整个句子的用法，意为“老是自赞她在剧中表演的角色，这件事当然令他人不快。”指代前面所说的整句话，用which。故答案为B。从句中插入of course增加了考测难度，解题时可先把它忽略。
6．It was about 600 years ago ____ the first clock with a face and an hour hand was made. ( ’97 )
A. that B. until C. before D. when
解析：本题考查强调结构It was … that…，不管被强调的是时间还是地点，that不变，该结构与定语从句非常相似，注意区别。

篇9：名词性从句 (人教版高三英语下册教学论文)
名词性从句
主语从句、表语从句、宾语从句和同位语从句，它们在复合句中的功用相当于名词，因此称为名词性从句，在句中分别作主语、表语、宾语和同位语。
1．When he will come is still unknown.
2．I don’t know who has watered the fields.
3．The problem is that we need more money.
4．Have you heard the news that our team won the game?
1． 主语从句：在复合句中作句子主语的从句。
引导词：连词that、whether;疑问代词who, what, which;
疑问副词when, where, how, why
(1) 连词that（无词意）, whether(是否), 在从句中不担任句子成分，只起连接作用; whether能引导主语从句，而if不能。
That you don’t like him has nothing to do with me.
Whether John will do this experiment remains a question.
（2）疑问代词who, what, which, 在从句中既作连接词又充当主语、宾语、表语、定语等。
Who will be sent abroad to further his studies is not announced.
What surprised me most was that such a little girl could play the violin so well.
Which school will win the prize is not known.
Whose dictionary has not been found is still unknown.
Whichever you take will be yours.
Whoever wants this book may take it.
Whatever was said here must be kept secret.
(3)疑问副词when, where, how, why在从句中充当时间状语、地点状语、方式状语、原因状语
When they will start hasn’t been decided yet.
Where the heroine went is not mentioned at the end of the story.
How he managed to finish the composition in such a short time is still a mystery.
Why he often comes here is known to us all.
(4)用it作形式主语的主语从句常用的句型有：
It’s said that…
It is certain that…
It seems/ happens that…
It’s possible/ important/ necessary/ clear that…,该句型从句的谓语动词使用虚拟语气形式：should+动词原形。
It is necessary that we should learn some English grammar.
2.表语从句：在复合句中作句子表语的从句
引导词有that, whether, what, which, who, whom, whose, when, where, why, how, because等
（1） 引导表语从句的that不省略，that仅起连接作用，在从句中不充当任何成分，无任何意义
The impression he makes on me is that he is a reliable person.
(2) the reason后面的表语从句只能用that引导，我们学生易犯“the reason is because…”的错误
The reason why the little actress has been such a success is that she is both clever and hard-working.
(3) 在表示命令order等，建议suggestion, advice等的名词后的表语从句中，谓语动词要用虚拟语气：
should+动词原形，should可省略
His suggestion is that we (should) hold another meeting to discuss the problem.
(4) whether可引导表语从句，表“是否”，它在从句中不充当成分，if不能引导表语从句。
The question is whether we can rely on him.
(5) 连接代词what, which, who, whom, whose除起连接作用外，还在从句中做主语、宾语、表语和定语。
That’s what he is worried about.（在从句作中宾语）
The problem is who can do the work.（在从句中作主语）
（6）连接副词when, where, why, how起连接作用外，还在从句中作状语。
That’s why I was late.
That is where he was born.
That is how he did it.
(6) 连词because引导表语从句，只用在
That/This/It is because…结构中
That is because she often works hard.
3．宾语从句：从句在句中充当宾语的成分。宾语从句可作谓语动词的宾语，也可作介词的宾语，也可作动词不定式等非谓语动词形式的宾语，还可作某些形容词的宾语从句。
Jenny thought (that) her teacher was unfair.
I’d like to know which one is your husband.
I am sure (that) he won’t mind.
It all depends on whether they will support us.
4.同位语从句：一般跟在某些名词后面，用以解释或说明前面的名词的内容。经常带同位语从句的名词有fact, news, message, doubt, possibility, idea, reason, belief, hope, thought, promise, suggestion, question等。
引导词有连词that, whether；连接代词who, which, what和连接副词where, when, why, how等
（1） that, whether只起连接作用，不在从句中作任何成分。
The idea that England stands for fish& chips…is past.
There is no doubt that the price of cars will go down.
The problem whether we should continue to do the experiment has been solved.(不能用if)
(2)连接代词who, which, what和连接副词where, when, why, how在从句中作相应成分。
He can’t answer the question how he got the money.
The question who should go abroad requires consideration.
I have no idea which one I should choose.
I’ve got a pretty good idea why they left early.
The question where we should go has not been discussed.
I have no idea when Jack will be back.
同位语从句与定语从句的区别：
We expressed the hope (that) they had expressed.
我们表达了他们曾经表达过的那种希望。（定语从句）
We expressed the hope that they would come to visit China again.
我们表示希望他们再来中国访问。（同位语从句）
1） 从语法角度上看，引导同位语从句的that是连词，只起连接作用，在从句中不作任何句子成分；而引导定语从句的that是关系代词，除起连接作用外，还在从句中作主语或宾语等句子成分。
2） 从语义角度上看，同位语从句与前面的名词hope是同位关系，表示hope的内容是they would come to visit China again。因而同位语从句是名词性的，其功能是对名词作补充说明；而定语从句与它前面的名词是所属关系，表示“…的”（他们曾经表示过的），起修饰作用，因此定语从句是形容词性的，其功能是修饰先行词。
3） 同位语从句的连词that不能省略，而定语从句的关系代词that，当其在从句中作宾语中，可省略，作主语也不可省略。
I’ve heard the news that he visited our factory.
I’ve heard the news that he told you the other day.
The news that the plane would take off on time made everybody happy.
The news that is spreading around the airport is that a heavy storm is coming.
The suggestion that students should learn something practical is worth considering.
The suggestion that they are considering is that students should learn something practical.

篇10：名词性从句 教案教学设计(译林牛津版英语高一)
Point out the function of each noun in the following sentences:
1.The world loves nature. （subject，object）
2.Knowledge is power . （subject， predicative）
3.We Chinese are peace-loving.(apposition)
名词性从句
名词性从句在功能上相当于名词名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语等
主语从句
宾语从句
表语从句
同位语从句
His job is important.What he does is important
This is his job.This is what he does every day
I don’t like his job。 I don’t like what he does every day.
I don’t know about the man, Mr. White I don’t know about the fact that he is Mr.White.
That the earth is round is right.
I want to know whether he comes or not.
Pay attention to what I said.
The reason is that he was late for school.
The fact that he died made us sad.
如何判断从句的类别？根据从句的位置判断。
①主语从句（从句位于动词前作主语）(it 做形式主语放于句首，主从放句末)
②宾语从句（从句位于动词后或介词，adj作宾语）
③表语从句（从句位于系动词之后作表语）
④同位语从句（从句位于特殊的名词如idea,fact,news等后
补充说明前面的名词）
Ⅰ指出下列各名词性从句的种类
At lunchtime, the radio weatherman reported that the mist would become a thick fog in the afternoon.
She wondered if the buses would still be running.
The truth is that the fog is too thick for the bus to run that far.
When we will start is not clear.
I had no idea that you were her friend.
名词性从句中的连接词有:
连词: that / whether / as if(though);
连接代词: what / who/ which / whose /
whatever / whoever / whomever
/ whichever，
连接副词: where / when / why / how
/ wherever / whenever
Ⅱ句型转换（1.判断主句，从句 2.看主句是否完整，不完整，则用从句补充，若完整则从句代替其中一个成分）
1.They are good doctors. He told us.
He told us that they were good doctors.
2. He hadn’t said anything at the meeting. The fact surprised us.
The fact that he hadn’t said anything at the meeting surprised us.
总结：当从句原来是陈述句时，变成名词性从句用that引导。（that无意义，不做成分）
3.Does your sister get up early? Do you know?
Do you know if/ whether your sister gets up early?
4.Do animals have the same senses as humans? I often wonder.
I often wonder if/ whether animals have the same senses as humans.
总结：当从句原来是一般疑问句时，变成名词性从句用if或whether引导。
5.When did he buy this new bike? Could you tell me?
Could you tell me when he bought this new bike?
6.My question is this: where will the lecture be given?
My question is where the lecture will be given.
总结：当从句原来是特殊疑问句时，变成名词性从句还用原来的特殊疑问词来引导。
总结：名词性从句必须用陈述句语序。另外，一般情况下，名词性从句均看作单数概念。由what引导的一般看后面的表语。宾语从句的时态一般与主句保持一致。
1.What we need is more time.
2.What we need are more English dictionaries.
Ⅲ 改错
1.That the earth turns around the sun are known to all.
2.When the meeting will be held haven’t been known yet.
3.I didn’t know that you will come.
4.He said that he is writing a story.
5.Could you tell me when will he arrive?
6.You can begin to see why does English have such strange rules.
主语从句
连词（除了 as if ,because）
if 引导的主语从句不可居于复合句句首。
Whether he will come on Wednesday is not certain. 不用if
it 做形式主语(由连词 whether , 连接代词 what,who,which 和连接副词 when,where,why,how 等引导.也常常后置:
It’ possible/important/necessary/clear… that……很可能/重要的是…/必要的是…/很清楚…
It’s said/ reported… that..据说/据报道…
It’s announced/declared that..已经通知/宣布…
It seems/appears/happens.. that…显然、明显、碰巧..
It’s no wonder that…并不奇怪/无疑…It’s a pity/a fact /a common knowledge (众所周知）
/ a common saying….（俗话说）
3.主语从句中 ，谓语动词一般用单数What引导的主语从句，可根据表语决定
What he needs _is_ that book.
What he needs _are_ some books
When and where we meet hasn’t been decided.
When we meet and where we meet haven’t been decided.
4主语从句的 “that”不能省。
宾语从句
连词（除了as if ,because）
由that引导的宾语从句(that 通常可以省略)
She told me that she would accept my invitation.
I heard that be joined the army.
I am afraid (that) I’ve made a mistake.
注意：that 引导的从句常跟在下列形容词后作宾语：anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。
但是：He told me (that) he would attend the international maths Olympic competition and that he would win the gold medal.
2.Lily wanted to know if /whether her grandma liked the handbag .
Let’s see if /whether we can find out some information about that city .
表“是否”时，在下列情况下用whether。
a. 主语从句
b. 表语从句
c. 同位语从句
d. 介词后的宾语从句
e.后接动词不定式 (whether to do sth.)
f .whether or not 连在一起引导宾语从句时不用if
1. I asked her __________ she had a bike.
3. We’re worried about ________ he is safe.
4. I don’t know ___________ he is well or not.
5. I don’t know ________ or not he is well.
6. I don’t know _______ to go.
3.时态.与主句相呼应： 如果主句是现在的时态 （包括一般现在时 ，现在进行时，现在完成时），从句的时态可根据实际情况而定，（包括一般现在时，一般过 去时，一般将来时，现在完成时等）
I know he lives here .
I know he lived here ten years ago .
I have heard that he will come tomorrow
如果主句是过去的时态（包括一般过去时，过去进行时），那么从句的时态一定要用相对应的过去的某种时态（包括一般过去时，过去进行时，过去将来时， 过去完成时）
I knew who lived here.
I saw she was talking with her mother.
He asked whether his father would come back
tomorrow.
He said that he had seen it .
当从句是客观真理，定义，公理，定理时用一般现在时。
The teacher said that the sun travels around the earth .
4 it 可以作为形式宾语think，believe，find， make, consider, feel
I think it necessary that you should read English aloud.
5否定的转移
若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如：
I don’t think he will come.
表语从句(可用as if ,because)不用if
The question is whether we can rely on him.
That’s because we were in need of money at that time .
He looked as if he was going to cry .
That’s why I was late .
That’s why + 结果
That’s because+原因
He is ill. That’s why he is absent.
He is absent. That’s because he is ill.
同位语从句（不用if ,because, as if）
同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导
He gave me a promise that he would buy a new car for me.
I have no idea whether he will come.
That 引导的同位语从句与定从的区别
The fact that he said nothing surprised everyone present.
The fact that he sais surprised everyone present.
(1)同位语从句--同位语从句和前面的名词是同位关系，对名词进行补充说明
定语从句 --定从和前面的名词是所属关系，对名词进行修饰，加以限定
(2) 同位语从句--that 只起连接作用，不作任何成分
定语从句 -- that 是关系代词，起连接作用和充 当宾语和主语
名词性从句中连词选择“三步法”
“一分二划三看”
一、“一分”即分清从句类型
二、“二划”即划分出从句（用括号表示从句）
（1）(That the erath is round) is true.（主语从句）
v
（2）Do you know（where he lives）?（宾语从句）
v
（3）My opinion is (that you should not go alone) .（表语从句）
v
（4）I don’t like the idea (that money is everything).（同位语从句）
n
三、“三看”即看从句句意是否完整：
1、句意不完整→缺连接代词 ①人 who,whoever（主语）
whom,whomever（宾语）
②物 what,whatever（主语、宾语）
which,whichever（主语、宾语）
2、句意完整
（1）缺连接副词 ：
①时间：when；②地点：where,wherever；③原因：why；④方式：how。
（2）缺不作成份的连词 ①有含义：if 、wherther（是否）；②无含义：that
篇11：英语名词性从句易混点区分
1.that引导的同位语从句与定语从句之区别?
that引导的同位语从句 that引导的定语从句 句法功能上
that只起连接从句的作用，无意义。 在从句中不充当句子成分。 不可省。
that替代先行词在从句中不仅起连接作用， 还充当一个句子成分。如在从句中作 动词的宾语时可省略。
意义上从句是被修饰名词的内容。 从句起限定作用，是定语 。
如：The news that Mr. Li will be our new English teacher is true. (同位语从句，that不可省) 李先生将是我们的新英语老师这个消息是真的。
The news (that) he told me yesterday is true. (定语从句，that在从句中作的宾语，可省)他昨天告诉我的消息是真的。
2.一些表示“建议、命令、要求”的名词后所跟的同位语从句中，谓语动词用虚拟语气should+动词原形表示。should可省。
如： This is our only request that this (should) be settled as soon as possible.这就是我们唯一的请求：尽快解决这个问题。
间隔同位语从句 同位语从句通常是跟在它解释或说明的名词后，但有些情况下，由于句子结构的原因，同位语从句不紧跟在名词后，而被其他的词隔开。
A warm thought suddenly came to me that I might use the pocket money to buy some flowers for my mother's birthday
简析：由于that从句太长，为避免句子失去平衡，此处用了间隔同位语从句
3.短语及固定句式后的同位语从句 I will come on condition that John is invited.如果约翰也被邀请的话，我就来。
On condition, on supposition, on the ground(s), on the understanding, with the exception, in spite of the fact, on the assumption及句式There BE+no doubt(hope,chance,possibility,…)后的that从句为同位语从句。
注意点
1：that和what的区别问题
能引导名词性从句的关系代词有who, whom, what, whose, which, whichever, whatever, whoever八个。
what是不能引导定语从句的。定语从句中如果缺少的成分是主语、宾语、表语，我们选择的是关系代词that或其他。现在山头换了，到了名词性从句的知识范围了。What在名词性从句中就很有用武之地了。还是分析成分，what 在从句中作的主语、宾语、表语。而that只是一个“连接词”，既不作什么成分，也没有什么意义。如:
What you did doesn’t agree with what you promised.
The matter of salary is what I care most if I decide to change my profession.
2. that和whether的区别问题
有时候，它们两个比较难以区别，因为，它们都是连接词，都在从句中不作成分。但是，它们之间最大的区别在于“意义”。即that在从句中既不作成分，也没有自己的意义;而whether就不同了。它虽然不在从句中作什么成分，但是它又意义，即“是否”。这就能够左右从句的意思，使从句所表达的意思变成一个还没有确定的因素。如：
I don’t know whether he can join us or not.
I’m sure that he can join us.
3. wh-词和wh-ever的区别问题
一般认为，wh-词在引导从句时，依然保留了很大部分的疑问词的本色，所以，它们引导的从句在意思上应该表达的是一个“问题”，如：“谁?什么?何时?何地?为何?怎么?”等。而wh-ever已经没有这层色彩，不再关心这样的“问题”，而是充满了让步的意味，多有“无论...”之意。如：
The police wanted to know who will benefit most from the old man’s death.警方想知道谁将从老人的去世中受益最多。
Whoever will benefit from the old man’s death will be questioned by the police.能从老人的去世之中受益的所有人都将受到警方的盘问。
篇12：高考英语名词性从句语法知识点讲解
主语从句宾语从句表语从句同位语从句
作及物动词宾语作介词宾语
that一般不省略可以省略一般不省略一般不省略一般不省略
Whether/if(是否)放于句首时只用whether用whether/if均可，但有区别只用whether只用whether只用whether
特殊疑问词注意语序要用陈述语序
名词性关系从句注意语序要用陈述语序
一、that 从句
1、主语从句
(1)that从句作主语时，常用it作形式主语，常见的句型有：
It+be+形容词(obvious, true, natural, surprising,good,wonderful,funny,possible,likely,certain,probable,etc.)+that从句
It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc.)+that从句
It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+that从句
(2)that可以省略，但that从句位于句首时，that不能省略。
2、宾语从句
(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。在可以接复合宾语的动词之后，如think, make, consider等，可以用it作形式宾语。
(2)That从句一般不能充当介词宾语，偶尔可作except, in 的宾语。
3、表语从句(that不可省略)
4、同位语从句
连词that引导同位语从句时，应在某些抽象名词之后，如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility等，对前面的名词起补充说明的作用，that在从句中不担当任何成分，不能省略。
二、whether/if从句
1、在表语从句和同位语从句中只能用whether不能用if;当主语从句放于句首时，只能用whether不用if;当it作形式主语，主语从句放在句末时用whether或if均可;discuss后引导宾语从句时，必须用whether。
2、在宾语从句中：
(1)及物动词后：whether从句中不能有否定式，宾语从句为否定句时用if;if不能与or not连用，但可以用whether or not;whether后可以加不定式。
(2)介词后：只能用whether,不用if。
三、特殊疑问词引导的从句
1、主语从句：特殊疑问词引导主语从句时，常用it作形式主语。
2、宾语从句
(1)常见的能接特殊疑问词引导的宾语从句的动词有see, tell, ask, answer, know, decide, find out, imagine, suggest, doubt, wonder, show, discuss, understand, inform, advise等。
(2)作介词宾语。
3、同位语从句、表语从句
四、名词性关系从句
What=the thing(s) which/that, whoever=anyone who, whichever=anyone/anything that, whatever=anything that, where=the place where, when=the time when
五、名词性从句的几个难点
(一)that不可省略的情况
1、主语从句，that从句置于句首时;
2、当一个句子有两个或多个并列的宾语从句时，引导第二和以后几个从句的that不可省略;
3、由it作形式宾语时，that引导的宾语从句中，that不可以省略。
(二)wh-ever与no matter wh-的用法区别
Wh-ever既可引导名词性从句，又可引导让步状语从句;而no matter wh-只能引导让步状语从句。
(三)as if/though, because, why可以引导表语从句
注意：because引导的表语从句，主语不能是reason或cause,而且since,as不能引导表语从句。
(四)that引导的同位语从句与关系代词that引导的定语从句的区别
That引导的同位语从句成分是完整的，that在从句中不担当任何成分;that引导的定语从句成分是残缺的，that在从句中充当主语、宾语或表语。

篇13：考研英语 突破长难句名词性从句
考研英语 突破长难句名词性从句
在句子中起名词作用的句子叫名词性从句。名词性从句的功能相当于名词词组， 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
在翻译的时候，主语从句、宾语从句、表语从句一般可以按照英语原文顺序来翻译。同位语从句有以下五种翻译方法：
①可以直接翻译在所修饰词后面。
②放在所修饰的名词前面，充当定语。
③译成独立句子：先翻译主句，然后用“就是……”或者“即……”引导出同位语从句，或者把同位语从句译成独立的句子，由冒号或破折号引出。
④用代词指代：先把同位语从句中的内容翻译出来，在后面用“这”或“那”等代词复指它，参加句子主体的构成。
⑤译成宾语 ：把同位语从句修饰的名词转译成动词，而把同位语从句译成宾语。
【真题例句1】
What is harder to establish is whether the productivity revolution that businessmen assume they are presiding over is for real.
【解析】
句子可拆分为：What is harder to establish is //whether the productivity revolution //that businessmen assume //they are presiding over// is for real.
主句为What is harder to establish is whether the productivity revolution is for real.主句包含两个从句成分：从句what is harder to establish作主语；whether the productivity revolution is for real作表语；that they are presiding over为定语从句修饰the productivity revolution； 此定语从句中businessmen assume为主谓结构的插入语。以what， whatever， whoever， whether， when， where， how， why等词引导的主语从句及表语从句在翻译的时候，一般可以按照英语原文顺序来翻译。
【参考译文】
难以确定的是，商界人士认为他们所主导的生产力革命是否真的存在。
【真题例句2】
It has also been proposed that just because we know so much about people intuitively， there has been less incentive for studying them scientifically： why should one develop a theory， carry out systematic observations， or make predictions about the obvious？
【解析】
该句可拆分为：It has also been proposed that //just because we know so much about people intuitively， // there has been less incentive //for studying them scientifically： //why should one develop a theory， //carry out systematic observations， //or make predictions about the obvious？
主句为：It has also been proposed.That…for studying them scientifically是主语从句，形式主语it的真主语。because we know so much about people intuitively是这个主语从句中嵌套的原因状语从句。冒号后面是一个简单句，对前面内容起解释说明作用。has been proposed， has been这个动词不好排除，但是如果你发现后面连词that后又有一个连词because， 说明that引导一个从句，而这个because引导的`应是这个从句的原因状语从句，很自然它后面需要有主句。所以这个动词只是从句中主句的谓语动词，并不是整个句子的谓语动词。develop， carry out， make在冒号后面句子中，不能成为主句谓语动词。由此确定主句谓语动词为has been proposed.
It is +过去分词+that从句开头的主语从句一般按顺序译出。
【参考译文】
还有解释说，正是由于我们对人的直觉了解太多，所以我们没有科学地研究这些直觉的动力：对于显而易见之事，人们为什么要建立一种理论、进行系统的观察或是作一些预言呢？

篇15：如何学好名词性从句 (人教版高三英语上册教学论文)
如何学好名词性从句
沈永铭
名词性从句是连贯初中到高中的英语重点语法概念，也是历年高考英语考试的一个考查热点。纵观历年高考英语试题，我们就能发现：高考英语对于名词性从句考查的重点就是名词性从句的引导词的选择、引导词之间的区别、名词性从句的陈述语序以及主从句时态基点一致性原则等。本文结合高考实际，重点给同学们谈一下如何掌握好名词性从句的问题。
一、什么是名词性从句？
在主从复合句中，不修饰任何句子中的成分而独立存在的从句就是名词性从句。名词性从句包括：主语从句、表语从句、宾语从句和同位于从句；名词性从句由连接代词和连接副词引导。
（一）主语从句
在主从复合句中位于谓语之前、充当主语功能的从句叫做主语从句。引导主语从句的连接词常有：连词that， whether；连接代词who，what，which以及其强调形式whoever，whatever， whichever；和连接副词when，where，how， why等。例如：
1． ____ fashion differs from country to country may reflect a cultural difference from one aspect．（春季上海）
A．What B．That C．This D．Which
2． ____ she couldn't understand was ________fewer and fewer students showed interests in her lessons．（上海）
A．What；why B．That；what C．What；because D．Why；that
3． ____has helped to save the drowning girl is worth praising．（99上海）
A．Who B．The one C．Anyone D．Whoever
4． ____ we can't get seems better than ____ we have．（NMET96）
A．What；what B．What；that C．That；that D．That；what
5． ____ we'll go camping tomorrow depends on the weather．（NMET96）
A．If B．Whether C．That D．Where
6． ____ he said at the meeting astonished everybody present．（MET93）
A．What B．That C．The fact D．The m atter
7． ____ you don't like him is none of my business．（92上海）
A．What B．Who C．That D．Whether
另外，当主语从句位于句首时，句子整体常常显得很笨重。因此，我们一般要把从句放在句末，前面用引导词it作形式主语，主语从句在复合句中充当真正主语。例如：
8．It worried her a bit ____ her hair was turning grey．（MET92）
A．while B．that C．if D．for
（二）表语从句
在主从复合句中，位于连系动词之后且充当表语的从句叫做表语从句。引导表语从句的连接词常有：连词that， whether；连接代词who，what，which；连接副词when，where，how，why以及其它连词as if，as though，because等。例如：
9．What the doctors really doubt is____ my mother will recover from the serious disease soon．（春季上海）
A．when B．how C．whether D．why
10．-I drove to Zhuhai for the air show last week．
-Is that ____ you had a few days off？（NMET99）
A．why B．when C．what D．where
11．Go and get your coat．It's____ you left it．（MET92）
A．there B．where C．there where D．where there
12．I had neither a raincoat nor an umbrella．____I got wet all through．（98上海）
A．It's the reason B．That's why C．There's why D．It's how
（三）同位语从句
在主从复合句中用充当同位语、说明所修饰的同位名词的内容的从句叫做同位语从句。同位语从句通常用在idea，news，fact，thought, promise，suggestion，belief，truth，reason,chance,information,news,conclusion,possibility, question,ask,doubt,wonder等同位名词的后面，说明该名词所表示的具体内容。引导同位语从句的连接词常有：连词that，连接副词how， when，where等.。
He left me a message that he would buy me a ticket to the rock concert.
13．Information has been put forward____ more middle school graduates will be admitted into universities．（2001上海）
A． While B．that C．when D．as
（四）宾语从句
在主从复合句中充当宾语、位于及物动词、介词或复合谓语之后的从句叫做宾语从句。引导宾语从句的连接词常有：连词that，whether，if；连接代词who，which，what以及其强调形式 whoever，whichever，whatever；连接副词 when，where，why，how等。例如：
14．When you answer questions in a job interview，please remember the golden rule：Always give the money exactly____ he wants．（春季上海）
A．what B．which C．when D．that
15．-I think it's going to be a big problem ．-Yes，it could be．

A．however B．whatever C．whichever D．whenever
21．Sarah hopes to become a friend of ____shares her interests．（95上海）
A．anyone B．whom ever C．whoever D．no m atter who
二、在学习名词性从句时还要注意的几方面事项：
1、在名词性从句中，当从句是疑问句时无比要遵循陈述语序的原则。例如：
22.No one can be sure ____ in a million years.(MET91)
A.what man will look like B.what will man look like
C.man will look like what D.what look will man like
23.____ is unknown to me.
A.Where does he live B.Where he lives C.He lives where D.Where he lives in
24．Someone is ringing the doorbell．Go and see ____．（2000上海）
A．who is he B．who he is C．who is it D．who it is
24．Can you make sure ____the gold ring ？（MET90）
A． where Alice had put B．where had Alice put
C．where Alice has put D．where has Alice put
25．You can't imagine ____ when they received these nice Christmas presents．（94上海）
A．how they were excited B．how excited they were
C．how excited were they D．they were how excited
2、what和that引导名词性从句时的区别。that引导名词性从句时只起连接词作用，本身无实际意义，在从句中不作任何成分； what引导名词性从句时本身有意义，即表示“什么”或“所……的事物”（＝the thing（s） which），同时又在从句中担任一定的成分,；在从句中指物或指事，作主语、表语、宾语或定语。短语动词do with就只能与what连用。
2、if和whether引导名词性从句时的区别。if和whether都可以用来引导名词性从句，但引导主语从句（位于句首时）、表语从句、同位语从句以及在介词之后引导宾语从句时要用whether，而不用if。
(1)if ,whether表“是否”时引导名词性从句；if表“如果”时引导条件状语从句；whether表“无论是否；不管是否”时引导让步状语从句。
例26：The WTO cannot live up to its name ____ it does not include a country that is home to one fifth of mankind.(NMET2000) A.whether B.while C.if D.even though
析：选C，句意为：“如果世贸组织不包括占世界人口五分之一的国家，就显得名不副实”。
例27：____ you will go there or not,I'll go there.
A.Whether B.If C.Unless D.While
析：选A，因为该句句意为：“无论你是否去，我都会去那里”。
4． who与whoever，what与whatever引导名词性从句时的区别。whoever引导名词性从句时相当于anyone who，those who。 whatever引导名词性从句时相当于anything that。试比较以下句子：
（1） Who broke the window is unknown．不知道是谁打破了窗户。
Whoever breaks the law will be punished．凡是犯法者都要受到惩罚。
（2） Do what you like．你爱干什么就干什么吧。
Do whatever you like．你爱干什么就干什么。（whatever比what语气更强）
5．在宾语从句中还要掌握好否定前移现象。所谓“否定前移现象”就是指当主句的主语是第一人称，且主句的谓语动词是think,believe;suppose;expect等感知动词时，人们常把对宾语从句的否定前移到主句中去的现象。这种现象的语言欺骗性较强，而且还影响到主从复合句的反意疑问句的后部句子的结构。例如：
（1）I don’t think that it’s right for you to do so.我认为你这样做是不对的。
这个句子中明显把对从句的否定转移到了主句中。
（2）We don’t believe that Tom can pass the driving test,_______?
A.do we B.don’t we C.can he D.can’t he
该主从复合句的反意疑问句的后部就是与从句保持一致，正确的选项为C项。
6．当fact,idea,reason,truth,chance,information,news,conclusion,possibility,believe,conclude等表示肯定意义的动词或名词前后的名词性从句一般为肯定句，名词性从句宜用that引导从句；当question,ask,doubt,wonder等表示疑问的名词或动词之前有了否定副词not或否定代词no时，从句一般为肯定句，宜用that引导从句。例如：
（1） The reason why he was absent this morning was that he was badly ill.
（2） There is no doubt that the clever and deligent will pass the college entrance examinations next year
7．在包含名词性从句的复合句中，我们都要遵循主从句动词时态基点一致性原则，即要么都用现在时态，要么都用过去时态。但是，当从句的内容为客观事实、客观真理、生活常识或谚语时，不受主从句时态一致原则的限制，仍要坚持用一般现在时；当从句的内容为历史的事实时，不受主从句时态一致原则的限制，仍用一般过去时。例如：
(1)Our physics teacher once told us that light travels faster than sound.
(2)It is known to us all that the People’s Republic of China was founded on October 1,1949.
8、在表示“命令”、“坚持”、“建议”或“要求”的动词或名词前后的名词性从句常用虚拟语气。
1）虚拟语气在宾语从句中的用法。由wish引导的宾语从句常表示说话人的一种强烈的却暂时无法实现的愿望。 How I wish she would be on my side!(But in fact it’s quite impossible.我多么希望她能站在我一边啊！
另外，在表示“命令”、“坚持”、“要求”或“建议”等意义的及物动词（order,command,demand,require,insist,suggest）之后的宾语从句中的谓语动词同样常使用虚拟语气，表示说话人的要求，其结构为：主语+should+动词原形，其中的should常可省略。The head teacher demanded that we (should finish) the task in time today.
但是，当insist表示“坚持认为”的意思时，或suggest表示“暗示”或“表明”之意时，宾语从句仍用陈述语气。试比较：
My parents insisted that I ( should) enter a key university.
My parents insisted that they were right.
The soldier’s pale face suggested that he was happy to have given his life to his motherland.
The monitress suggested that we (should ) hold a class meeting tomorrow afternoon to discuss the problem.
2）、虚拟语气用在主语从句中。
在句型 “It is important (necessary, strange, natural) that .... ” 中，that 后面的从句中的谓语动词常用：“ should + 动词原形 ”。例如：
It's necessary that we should have a walk now. 我们有必要出去散散步。
It's natural that she should do so. 她这样做是很自然的。
It's important that we should take good care of the patient. 重要的是我们要照顾好病人。
同理，在表示“命令”、“坚持”、“要求”或“建议”等意义的名词前后的主语从句、标语从句和同位语从句中的谓语动词同样用虚拟语气，既：“主语+(should)+ 动词原形”的句型。例如：
His suggestion /advice is that we should start early tomorrow morning.
It is necessary that a college student ________ at least a foreign language．（上海’1993）
A．masters B．should master C．mastered D．will master
二、练习与检测

篇16：《名词性从句》讲义 (人教版高三英语下册教学论文)
《名词性从句》讲义
一、定义：在复合句中相当于一个名词，做主语、宾语、表语、同位语的从句。
二、引导词：
1. 连词: that , if, whether, as if
2. 连接代词: who , what, which, whose, whom以及wh+ever
3. 连接副词: when, where, why, because, how
三、引导词的作用：
1. 连词只有连接的功能，而不在从句中充当句子成分。
2. 连接代词和连接副词不但有连接的功能，同时还要在从句中充当特定的句子成分，主
语、宾语、表语、定语、状语。
主 语 从 句
基本概念
1． 定义：在复合句中作句子主语的从句叫做主语从句。
2． 构成：关联词+简单句
3． 引导主语从句的关联词有三类：
连词that、whether;
疑问代词who, what, which;
疑问副词when, where, how, why
⑴ 连词that（无词意）, whether(是否), 在从句中不充当句子成分，只起连接作用; whether
能引导主语从句，而if不能。
That you don’t like him has nothing to do with me.
Whether John will do this experiment remains a question.
⑵ 疑问代词who, what, which, 在从句中既作连接词又充当主语、宾语、表语、定语等。
Who will be sent abroad to further his studies is not announced.
What surprised me most was that such a little girl could play the violin so well.
Which school will win the prize is not known.
Whose dictionary has not been found is still unknown.
Whichever you take will be yours.
Whoever wants this book may take it.
Whatever was said here must be kept secret.
⑶ 疑问副词when, where, how, why在从句中充当时间状语、地点状语、方式状语、原
因状语
When they will start hasn’t been decided yet.
Where the heroine went is not mentioned at the end of the story.
How he managed to finish the composition in such a short time is still a mystery.
Why he often comes here is known to us all.
难点
1． 主语从句能用it作形式上的主语，而把真正的主语放在后面。常以it作形式主语的
句型有：
A. It+be+形容词(well-known, obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如：
It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。
It is probable that he told her everything. 很可能他把一切都告诉她了。
B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, common
Knowledge, a surprise, a fact, etc.)+that从句。如：
It’s a pity that we can’t go. 很遗憾我们不能去。
It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。
C. It+be+过去分词(said, reported, thought, expected, decided, announced, arranged,
etc.)+that从句。如：
It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。
It is reported that China has sent another man-made earth satellite into orbit.
据报道中国又成功地发射了一颗人造地球卫星。
It has been suggested that much should be done to prevent the river from being
polluted. 有人建议应做更多的工作阻止河流受到污染。
D. It appears / seems that…… （似乎……）
It happens that…… （碰巧……）
It occurred to me that…… （我突然想起……）
It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。
It happened that I was out that day. 碰巧我那天外出了。
E. It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从
句。如：
It doesn’t matter whether she will come or not. 她是否来这无关紧要。
It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。
F. 当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句
后置。如：
Is it true that the scientist will give us a lecture next week?
下周那位科学家将给我们作报告是真的吗？
Does it matter much that they will not come tomorrow? 他们明天不来很要紧吗？
G. 当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。如：
How strange it is that the children are so quiet! 孩子们这么安静真奇怪！
2． 注意连接代词whoever, whatever, whichever等引导主语从句的含义
Whoever comes will be welcome. (whoever=the person who) 来的人将受到欢迎。
Whatever he did was right. (whatever=the thing that) 他所做的事情是正确的。
Whichever of you comes in will receive a prize. (whichever=anyone of you who)
你们当中不论哪个进来将会得到奖励。
表 语 从 句
基本概念
1． 定义：用作表语的从句叫做表语从句。
2． 构成：关联词+简单句
3． 引导表语从句的关联词的种类：
(1) 从属连词that。如：
The trouble is that I have lost his address. 麻烦是我把他的地址丢了。
(2) 从属连词whether, as, as if。如：
He looked just as he had looked ten years before. 他看起来还与十年前一样。
The question is whether they will be able to help us. 问题是他们是否能帮我们。
注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如：
All this was over twenty years ago, but it’s as if it was only yesterday.
这都是20多年前的事了，但宛如昨天一样。
能跟表语从句的谓语动词一般为系动词be, seem, look等。如：
It looked as if it was going to rain. 看起来天要下雨了。
(3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever
连接副词 where, when, how, why。
如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。
The question is how he did it. 问题是他是如何做此事的。
That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。
难点
1． 连词because可引导表语从句。如：
I think it is because you are doing too much. 我想这是因为你做得太多。
2． 引导表语从句的that不省略，that仅起连接作用，在从句中不充当任何成分，无任何
意义
The impression he makes on me is that he is a reliable person.
他给我的印象是他是一个可靠的人。
3． the reason后面的表语从句只能用that引导，我们学生易犯“the reason is because…”
的错误
The reason why the little actress has been such a success is that she is both clever and
hard-working.
4． 在表示命令order等，建议suggestion, advice等的名词后的表语从句中，谓语动词要
用虚拟语气：should+动词原形，should可省略
His suggestion is that we (should) hold another meeting to discuss the problem.
5． whether可引导表语从句，表“是否”，它在从句中不充当成分，if不能引导表语从句。
宾 语 从 句
基本概念
1． 定义：用作宾语的从句叫宾语从句。
2． 构成：关联词+简单句
3． 引导宾语从句的关联词有三类：
(1) 从属连词that。如：
He told us that he felt ill. 他对我们说他感到不舒服。
I know he has returned. 我知道他已经回来了。
注： that在引导宾语从句时也并非任何情况下都可以省略。在以下情况下，that不能
省略。
① Everybody could see what happened and that Tom was frightened.(and连接两个
宾语从句，that宾语从句放在and的后面时，that不能省略。)
大家都会看出所发生的事情并知道Tom非常害怕。
② I know nothing about him except that he is from the south.(that引导的宾语从句作
介词宾语时，that不能省略。) 对他我一无所知，只知道他是南方人。
③ That he ever said such a thing I simply don’t believe. (that从句位于句首时，that
不可省略。) 我简直不相信他曾说过这样的话。
④ We decided, in view of his special circumstances, that we would admit him for a
probationary period. (主句谓语动词与that从句之间有插入语，that不可省略。)
鉴于他的特殊情况，我们决定应允他一段试用期。
(2) 从属连词if/whether。如：
I doubt whether he will succeed. 我怀疑他是否会成功。
I don’t know if you can help me. 我不知道你能否帮助我。
(3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever
连接副词 where, when, how, why。
Who or what he was, Martin never learned.
他是什么人？他是干什么的？马丁根本不知道。
I wonder what he’s writing to me about. 我不知道他要给我写信说什么事。
I’ll tell you why I asked you to come. 我会告诉你我为什么要你来。
You may do what you will. 你可做任何你想做的事。
4． 介词宾语从句
宾语从句也可用作介词的宾语。如：
He was deeply displeased by what had occurred that day.
他对那天发生的事感到很不快。
I walked over to where she sat. 我走向她坐的地方。
I am curious as to what he will say. 我很想知道他要说什么。
Your success will largely depend upon what you do and how you do it.
你是否成功将主要取决于你做什么和怎样做。
有时介词可以省略。如：
I don’t care (for) who marries him. 我不管谁跟他结婚。
Be careful (as to) how you do that. 你要注意做这件事的方式。
难点
1． 如果宾语从句后还有宾语补足语，则用it作形式宾语，而将宾语从句后置。如：
We thought it strange that Xiao Wang did not come yesterday.
我们认为小王昨天没来是奇怪的。
He has made it clear that he will not give in.
他已表明他不会屈服。
2． 作介词的宾语：连词that引导的名词性从句很少作介词的宾语，只用在except, but, in
后。其他一些介词的宾语从句如果由连词that引导，则需用it作形式宾语。如：
He is a good student except that he is careless.
他是一个好学生，只是有点粗心。
You may rely on it that I shall help you. 你可以指望我会帮助你的。
介词宾语不可以用which来引导，而要用what来引导。如：
Are you sorry for what you’ve done?
你为你所做的一切感到内疚吗？
3． 某些形容词或过去分词后常接宾语从句，这类形容词或过去分词有sure, glad, certain,
pleased, happy, afraid, surprised, satisfied等，连词that可省略。如：
I am not sure what I ought to do. 我不能确定我该做什么。
I’m afraid you don’t understand what I said. 恐怕你没领会我说的意思。
I’m surprised that I didn’t see all that before. 我好奇怪，我以前没看到过。
Mother was very pleased her daughter had passed the exams.
妈妈为她的女儿通过了考试而感到高兴。
4． 连词whether (…or not)或if引导的宾语从句
if和whether引导的宾语从句可以互换使用，但whether常和or not连用，if一般不
与or not连用。如：
I wonder whether it is true or not. 我不知它是真是假。
用if引导宾语从句如果会引起歧义，应避免使用if而用whether。试比较：
Please let me know if you want to go.
Please let me know whether you want to go.
if从句可理解为宾语从句，意为“请告诉我你是否想去”；此句又可理解为条件状语从句，意为“如果你想去的话，请告诉我一声”。
5． 宾语从句的否定转移。在think, believe, suppose, expect等动词后的宾语从句，有时谓
语尽管是否定意思，却不用否定形式，而将think等动词变为否定形式。如：
I don’t think you are right. 我认为你错了。
I don’t believe they have finished their work yet. 我相信他们还未完成他们的工作。
I don’t suppose he cares, does he? 我想他不在意，是吗？
6． 宾语从句的时态变化规律：
(1) 当主句是一般现在时态时，从句可根据需要用任何时态。
(2) 当主句是一般过去时态时，从句只能使用过去范围内的任何时态。但客观真理除外。如：The teacher said that the earth goes round the sun. 老师说地球绕着太阳运行。
同 位 语 从 句
基本概念
1． 定义：用作同位语的从句叫做同位语从句。
2． 用法：
① 同位语从句的先行词多为fact, news, idea, thought, question, reply, report, remark等，关联词多用从属连词that。如：
They were all very much worried over the fact that you were sick.
对你生病这件事，他们都很焦虑。
Where did you get the idea that I could not come?
你在哪儿听说我不能来？
Early in the day came the news that Germany had declared war on Russia.
德国已对俄国宣战的消息一大早就传来了。
注：同位语从句偶尔由从属连词whether引导。如：
I have no idea whether he’ll come or not. 我不知道他是否来。
② 连接代词who, which, what和连接副词where, when, why, how亦可引导同位语从
句。
The question who should do the work requires consideration.
谁该干这项工作，这个问题需要考虑。
We haven’t yet settled the question where we are going to spend our summer vacation.
到哪儿去度暑假，这个问题我们还没有决定。
It is a question how he did it.
那是一个他如何做了此事的问题。
难点
1． that引导的同位语从句与定语从句之区别：
We expressed the hope (that) they had expressed.
我们表达了他们曾经表达过的那种希望。（定语从句）
We expressed the hope that they would come to visit China again.
我们表示希望他们再来中国访问。（同位语从句）
① 从语法角度上看，引导同位语从句的that是连词，只起连接作用，在从句中不作任何句子成分；而引导定语从句的that是关系代词，除起连接作用外，还在从句中作主语或宾语等句子成分。
② 从语义角度上看，同位语从句与前面的名词hope是同位关系，表示hope的内容是they would come to visit China again。因而同位语从句是名词性的，其功能是对名词作补充说明；而定语从句与它前面的名词是所属关系，表示“…的”（他们曾经表示过的），起修饰作用，因此定语从句是形容词性的，其功能是修饰先行词。一般来说，我们可以将同位语从句改写成“主语 + be + 表语”结构。
The hope was that they would come to visit China again.
③ 同位语从句的连词that不能省略，而定语从句的关系代词that，当其在从句中作宾语中，可省略，作主语也不可省略。
I’ve heard the news that he visited our factory.
I’ve heard the news that he told you the other day.
The news that the plane would take off on time made everybody happy.
The news that is spreading around the airport is that a heavy storm is coming.
The suggestion that students should learn something practical is worth considering.
The suggestion that they are considering is that students should learn something practical.
The news that Mr. Li will be our new English teacher is true. (同位语从句，that不可省。)
李先生将是我们的新英语老师这个消息是真的。
The news (that) he told me yesterday is true. (定语从句，that在从句中作told的宾语，可省。)
他昨天告诉我的消息是真的。
2．引导定语从句的when, where, why是关系副词， 在其前面分别有表示时间、地点、原因或方式意义的名词作先先词。
I will never forger the day when I joined the League.
我永远不会忘记我入团的那一天。
The factory where I once worked has changed a lot.
我曾经工作过的那家工厂发生了巨大的变化。
That’s the reason why she didn’t come to the meeting.
这就是她为什么没有到会的原因。
当when, why, where引导同位语从句时，它们为连接副词。虽然它们在从句中充当句子成分，但前面却没有与其意义相当的先行词。
I have no idea when he will be back. 我不知道他什么时候回来。
The problem where we got the machine needed has already been solved.
我们到哪里去弄所需机器的问题已经解决了。
He has solved the question why he was ill. 他已经解决了他为什么生病这个问题。
3． 一些表示“建议、命令、要求”的名词后所跟的同位语从句中，谓语动词用虚拟语气should+动词原形表示。should可省。如：
This is our only request that this (should) be settled as soon as possible.
这就是我们唯一的请求：尽快解决这个问题。
