表语从句

1、概述

用作表语的从句叫作表语从句，它位于主句中的连系动词之后。引导表语从句的词有从属连词that、whether、as though(if)；关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等；关系副词when, where, why, how, however, whenever, wherever等。可以接表语从句的连系动词由be, look, remain, seem等。That引导表语从句时，在口语中，间或可以省略。

The trouble is that we are short of money.困难是我们资金短缺。

That is why stone walls are used instead of fences around New England fields.这就是为什么在新英格兰用石头墙而不用栅栏的原因。

At that time, it seemed as if I couldn't think of the right word anyhow.当时,我似乎怎么也想不出一个恰当的字眼来。

2、由从属连词that，whether引导的表语从句。

that在引导表语从句时无词义，而whether有词义，意为、“是否”。这时主句的主语常常是些抽象名词，如question(问题)，trouble(麻烦)，problem(问题)，result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由)等。表语从句对主句主语进行说明、解释，使主语的内容具体化。

The trouble is(that)she has lost his money.麻烦的事是他丢了钱。

The question is whether we need more ice cream.问题是我们是否还需要一些冰淇淋。The problem was that it was too valuable for everyday use.问题是它作为日常之用太贵重了。

What she couldn’t understand was that fewer and fewer students showed interest in her lessons.我们不能理解越来越少的学生对他的课不感兴趣。

3、由关系代词引导的表语从句。

关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句，在句中作主语、宾语、表语，关系代词不能省略。The question is which of us should go.问题是我们哪一个应该去。The problem was who could do the work.问题是谁能做这项工作。That's what he is worrying about.那就是他在担心的事。That's what we should do.那是我们应该做的。

4、由关系副词引导的表语从句。

Go and get your coat.It's where you left it.去把雨衣拿来。就在你原来放的地方。I had neither a raincoat nor an umbrella.That’s why I got wet through.我们既没伞也没雨衣，这是我们淋湿的原因。

That is how mice ruin many stores of grain every year.那就是老鼠是怎样每年损害大量粮食的。

That is what he is worried about.那就是他所担心的。

5、由连词because，as if/as though等引导的表语从句。

It looked as if it was going to snow.看起来好像要下雪了。

That's because we never thought of it.这是因为我们从未想过此事。It seems as if he didn’t know the answer.好像他不知道答案。可以接表语从句的系动词有：

1：be（being,been,am,is,are,was,were)2: feel , seem , look, appear ,sound, taste , smell 3: stand , lie , remain ,keep, stay 4: become ,get , grow , turn ,go ,come, run, fall 5: prove, turn out 系动词的固定搭配: come true, fall asleep, fall ill, go bad, come right, run wild 连接词：that / whether /as if /as though(if不引导表语从句)连接代词：who / whom / whose / which / what 连接副词：when / where / why / how / because 注：引导表语从句的连词that间或可以省略。

The truth is（that）I didn't go there.事实是我没去那儿。

［考题1］ The traditional view is ____ we sleep because our brain is “programmed” to make us do so.A.when B.why C.whether D.that

［答案］ D

［解析］下划线处之后是包含一个原因状语从句的表语从句，如果看不出它是充当整个句子结构的表语从句将难以把握整个句子的意思。因此，应选择可引导名词性从句且不充当任何成分的that。

［考题2］ You are saying that everyone should be equal, and this is ____ I disagree.A.why B.where C.what D.how

［答案］ B

［解析］下划线处的引导词引导系动词is后的表语从句并在该表语从句中充当地点状语(“disagree”属于不及物动词，“I disagree”本身是完整的主谓结构)，下划线应填入引导词where，表语从句“where I disagree”的意思是“我不同意之处、我不同意的地方”。

［考题3］ — 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］ A

［解析］下划线处的引导词引导与系动词is连用的表语从句并在该表语从句中充当原因状语，下划线应填入表示“因此„„”(指因某种原因所造成的结果)的引导词why。

［考题4］ ____ 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］ A

［解析］第一个下划线处的引导词引导主语从句并在该主语从句中充当宾语，特指她所不理解的事情，应填入关系代词型的引导词what；第二个下划线处表示“因此„„”(指因某种原因所造成的后果，由why引导对应的名词性从句)而不是“为什么„„”(指原因、理由，由because引导对应的名词性从句)，应填入引导词why。

［考题5］ ____ 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］ B

［解析］第一个下划线处的引导词引导主语从句并在该主语从句中充当主语，特指令校方骄傲的事情，应选用关系代词型的引导词what；第二个下划线处引导表语从句表示原因、理由，应由that引导对应的名词性从句。

［考题6］ — Are you still thinking about yesterday’s game?

— Oh, that’s ____.A.what makes me feel excited B.whatever I feel excited about

C.how I feel about it D.when I feel excited

［答案］ A

［解析］ A选项的意思是“令我感觉激动的事物”； B选项的意思是“我觉得激动的任何事物”； C选项的意思是“我对它感觉的方式”； D选项的意思是“令我感觉激动的时间”。四个选项中A最适合跟代表“game”的主语that对应，充当表语从句。

表语从句与宾语从句的关系

不属于的

宾语从句和表语从句都属于名词性从句。其作用跟名词在句中的作用相同。故充当宾语的句子叫宾语从句，充当表语的句子叫表语从句。

宾语从句

(1)对于宾语从句要掌握以下三点

①语序: 从句的语序必须是陈述句语序, 即“主语 + 谓语”这种形式。

②时态: 当主句是一般现在时或一般将来时的时候, 从句可以是任何时态, 而当主句是一般过去时的时候, 从句, 从句时态必须是过去时范围的时态, 即(一般过去时, 过去进行时, 过去完成时, 过去将来时)。

③连接词: 当从句意思完整, 主句意思肯定时, 连接词用that, 且可以省去, 当从句意思完整, 主句意思不确定或含否定含意时, 常用if或whether(是否), 当从句意思不完整时, 连接词则是代替不完整部分的特殊疑问词。

表语从句

在句子中起表语作用的从句叫做表语从句，位于主句系动词的后面。表语从句的引导词和主语从句的引导词相同。也是名词性从句的一种。

如： What the police want to know is when you enred red the room警察想知道的是你什么时候进的房间。

The The trouble is that we are short of funds困难是我们缺乏资金。

This This is what we should do这是我们应当做的。

That”s s why I want you to work there那就是我要你在那儿工作的原因。

His His first question was whether Mr.Smith had arrived yet他的第一个问题是史密斯先生到了没有。

注意：从句中的疑问句用正常语序，即陈述语序。

as as if, as though, becau也可用来引导表语从句。

She She seems as if she had done a great thing她看起来好像做了一件大事。

It It is because you eat too much那是因为你吃得太多了。

第三篇：主语从句讲解与练习

主语从句

一、概述：在句子中起名词作用的各种从句统称为名词性从句。根据它们在句中的语法作用，这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。二.主语从句主要有三类：

（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。That you are so indifferent bothers me.你如此冷淡使我很烦恼。

That she survived the accident is a miracle.她在事故中幸免于难简直是奇迹。

（2）用连词 whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。例如：Whether she is coming or not doesn’t matter too much.她来不来都无关紧要。

（3）用连接代词引导的主语从句(在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分).例如：What you need is more practice.你所需要的是更多的训练。

What I want to know is this.我想知道的就是这事。Whatever we do is to serve the people.我们无论做什么都是为人民服务。

（4）用连接副词when, where, why, how引导的名词性从句(其连接副词有含义,在句中作状语。)eg:Where we should leave it is a problem.When they will come hasn’t been made pubic.他们什么时候来还不知道。三.注意点: 1.it 做形式主语,而将主语从句放在句末（尤其是当谓语较短时）。例如：That light travels in straight lines is known to all.光沿直线传播，这是众所周知的事。

=It is known to all that light travels in straight lines.众所周知光沿直线传播。

When the plane is to take off has not been announced.飞机何时起飞还没有宣布。

= It has not been announced when the plane is to take off.还没有宣布飞机何时起飞。

(当what引导的主语从句表示“…的东西”时，一般不用it作形式主语。)错:It is a book what he wants.对:What he wants is a book.他想要的是本书。

例如：Has it been settled who will be sent to carry out the task ? 谁将被派去执行这项任务决定了吗？固定用法和译法

（1）It is +名词+从句

It is a fact that… 事实是……

It is good news that … ……是好消息 It is a question that … ……是个问题

It is common knowledge that … ……是常识

类似的名词还有：a pity；a wonder；a good thing； no wonder； surprise等。例如：It is a mystery to me how it all happened.这一切是怎么发生的是个谜。

It is common knowledge that the whale is not a fish.鲸鱼不是鱼，这是常识。

It is no surprise that Bob should have won the game.鲍勃会赢得这场比赛，这不足为奇。（2）It is +形容词+从句

It is necessary that … 有必要…… It is clear that … 很清楚…… It is likely that … 很可能……

It is important that … 重要的是……

类似的形容词还有：strange;natural;obvious;true;good;wonderful;possible;unlikely;quite;unusual;certain;evident;worth-while;surprising;interesting;astonishing, etc.例如：It is obvious that conductors and insulators are both important in industry.很明显导体和绝缘体在工业中都很重要。It is doubtful whether she will be able to come.她是否能来令人怀疑。

It was really astonishing that he refused to talk to you.他拒绝和你说话真是令人惊讶。

It is essential that he should be here by the weekend.周末之前，他应该到这里是必要的。

It seems obvious that we can not go on like this.很明显我们不能这样下去了。（3）It is +过去分词+从句 It is said that … 据说……

It is reported that … 据报道……

It has been proved that … 已证明…… It must be proved that… 必须指出……

It is estimated that the vase is 2000 years old.据估计这个花瓶有2000年的历史。

It is used to be thought that a new star must be due to a collision between two stars.过去一直认为新星是由于两颗星星之间碰撞产生的。

It has not been made clear when the new road is to be opened to traffic.还没弄清楚这条路将开始通车。

It does not matter if I missed my train, because there is another later.没有赶上这趟火车没有关系，稍晚还有一趟。It happened that I saw him yesterday.碰巧我昨天看见他了。

当“及物动词 + 宾语”较短时，也可用这种结构。

例如：It shocked me that Peter did not tell anybody where he was.让我吃惊的是彼得没有告诉任何人他在哪里。It does not interest me whether you go or not.我对你去不去不感兴趣。

2.只用whether不用if引导主语从句.二、主语从句与形式主语it 有时为了考虑句子平衡，通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。这分三种情况：

(1)对于以连词that引导的主语从句，通常用形式主语代主语从句： It’s a pity that he didn’t come.很遗憾他没来。

It is important that he should know about this.他必须知道此事。It’s vital that we be present.我们出席是至关重要的。

It was intended that you be the candidate.大家的意图是让你当候选人。It is important that this mission not fail.这项使命不失败至关重要。

It is essential that a meeting be convened this week.本周开一次会非常重要。It is appropriate that this tax be abolished.废除这个税是恰当的。

It’s unfair that so many people should lose their jobs.竟有这么多人失业这是不公平的。It’s amazing that she should have said nothing about it.她竟未谈及此事令人惊讶。

It’s unthinkable that they should deny my request.他们竟然拒绝我的请求，这是不可思议的。That they should refuse to sign the petition required great courage.他们拒绝在请愿书上签字这是需要很大勇气的。

(2)对于以连接代词(副词)引导的主语从句，可以使用形式主语代主语从句，也可直接在句首使用主语从句：

Whether they would support us was a problem.他们是否会支持我们还是一个问题。It was a problem whether they would support us.他们是否会支持我们还是一个问题。

It remains to be seen whether it will do us harm or good.它对我们是利是害，还得看看再说。(3)对关系代词型what引导的主语从句，通常直接将主语从句放在句首。如： What we need is money.我们需要的是钱。

What I want to know is this.我想知道的就是这一点。有时也可将助用形式主语。如：

It is clear enough what he meant.他是什么意思很清楚。(4)如果句子是疑问句，则必须用带形式主语it的结构：

Is it true that he is the girl’s father? 他是那女孩的父亲，是真的吗？

How is it that you are late again? 你怎么又迟到了？(from www.xiexiebang.coming B.If he is coming C.That coming D.Whether he’s coming 11.It’s _____ he’ll be able to come.A.doubt whether B.doubtful C.doubt it D.doubtful whether 12._____ he is at work in the heart of the big city or at home in the quiet suburb, Dick’s life is tie

2、B。考查主语从句。从句中动词do缺少宾语，故选what，what引导的从句在句中作主语。

3、B

4、B

5、【解析】C.考查主语从句，并在主语从句中作fear的宾语what的用法。

6、C

7、A解析：it 是形式主语，真正的主语是whether 引导的从句。句意：校长是否支持我们的活动很重要。故选A项。

8、D解析：what 在这里引导主语从句，选D项。此题要注意分析句子结构，如果题目改为：①________ is known to us all, the Chinese government has spared no efforts to protect people from fake food.该句空处应用As, As 引导非限制性定语从句；②________ is known to us all that the Chinese government has spared no efforts to protect people from fake food.该句空处则应用It, It 作形式主语。

9、C解析：句意：温家宝总理访问美国让两国之间的关系更加密切。“That Premier Wen Jiabao visited the United States”是主语从句，that 在从句中只起连词作用，不作句子成分，本身没有词义，但是不可省略。

10、D解析：it是形式主语，代替后面的主语从句。主语从句结构完整，故用that引导。that在主语从句中不作成分，但不能省略。

11、B解析：句意：尽管大约有两千名病人已经服用了这种药物，但是它会产生什么样的副作用现在还不能确定。根据句意可知应该选择B项引导主语从句。what在这里实际上是作为形容词来修饰后面的“side effect副作用”。一起作从句中bring about的宾语。

12、C解析：句意：村民们已经知道我们要重建这座桥。分析句子结构可知，known后跟宾语从句，省略了连接词that。此宾语从句中又包含一个主语从句，主语从句中do缺少宾语，所以用what引导该从句作整个宾语从句的主语，答案为C项。

13、A解析：whether“是否”；when“当„„时候”；which“哪一个”；where“哪儿”。句意：旧车站是否要被现代化的旅馆所代替仍在讨论中。根据句意可知选A项。

14、B解析：句意：“巴巴拉·琼斯给予她粉丝的是诚实和快乐。”“________Barbara Jones offers to her fans”在句中作主语，为主语从句。what引导主语从句并且在从句中作offers的宾语，故选B项。which表示“哪一个”；whom表示“谁”。均不符合句意。

15、D解析：句意：这名男子没有早点报告这次事故的原因根本没有搞清楚。it在句中是形式主语，真正的主语是why引导的主语从句。

16、C

17、C

18、D

19、A

【答案】

1.Who will pick him up 2.Whether we can finish the work on time 3.That you don’t like him 4.When he will go abroad 5.What matters most

6.that her hair was turning grey 7.walk in space 8.Whoever/Anyone who breaks the law 9.It seems impossible that 10.What made the school proud Key:

I． 1.Why

2.that 3.Which 4.Whoever

5.Whether 6.that 7.How

8.what

9.that

10.Who

II． 1.That → What

2.when → that

3.If → Whether

4.Whether → That

5.which → what

6.Whatever → Whoever

7.Why → How

8.When → Who

9.How → Whether

10.when → that 1.在句首加That（并将Light改为light）。that虽无词义但引导主语从句位于句首时不能省略。

2.将If改为Whether。if, whether都可表示“是否”，但if不能引导位于主句之前的主语从句，它可以引导位于主句之后带有形式主语it的主语从句。

3.将That改为What。that引导主语从句时无词义。What the professor said表示“教授所说的”。

4.将will置于trees之后。主语从句要用陈述句语序。

5.将No matter who改为Whoever。引导让步状语从句时二者可互换，但引导名词性从句时

只能用whoever。

6.将remain改为remains。主语从句表示单一概念时，谓语要用单数形式。

7.has要改为have。主语从句表示复数概念时，谓语要用复数形式。

8.将made改为（should）make。在“It is requested / ordered / suggested + that从句”中，从句要用虚拟语气，即谓语用“should + 动词原形”，should可省略

第四篇：高二主语从句练习

二.主语从句主要有四类：（1）由连词that引导的主语从句:引导词that无含义/在句中不做成分/不可以省。例如：That you will win the medal seems unlikely.That you are so indifferent bothers me.That she survived the accident is a miracle.（2）用连词 whether 引导的主语从句: whether有含义(是否)/在句中不做成分/不可以省。

注意：引导主语从句，不能用if，只能用whether。

例如：Whether we will hold a party in the open air tomorrow depends on the weather.Whether she is coming or not doesn’t matter too much.（3）用连接代词引导的主语从句

whatever, whoever在主语从句中不含疑问意义。它引导主语从句，并在从句中作主语、宾语、表语等。

whatever = anything that;whoever = anyone who。要注意和whatever, whoever引导的让步状语从句的区别。

如： Whoever breaks the law should be punished.（主语从句）

（＝Anyone who breaks the law should be punished.）

Whoever breaks the law, he should be punished.（让步状语从句）

（＝No matter who breaks the law, he should be punished.）

（4）用连接副词when, where, why, how引导的名词性从句(其连接副词有含义,在句中作状语。)例如:Where we should leave it is a problem.When they will come hasn’t been made pubic.三.由 it构成的主语从句

（1）由连词that引导的主语从句，在大多数情况下会放到句子的后面，而用代词it作形式主语。

例如：That light travels in straight lines is known to all.=It is known to all that light travels in straight lines.When the plane is to take off has not been announced.= It has not been announced when the plane is to take off.(但当what引导的主语从句表示“…的东西”时，一般不用it作形式主语。)错:It is a book what he wants.对:What he wants is a book.另外，需要注意的是，it作形式主语代替主语从句时，要注意和as引导的定语从句的区别。试比较：

It was reported that the US was under the terrorist attack.As was reported, the US was under the terrorist attack.（2）常见用it作形式主语的复合句结构 It is +名词+从句

It is a fact that… 事实是……

It is good news that … ……是好消息 It is a question that … ……是个问题

It is common knowledge that … ……是常识

It is necessary that … 有必要…… It is clear that … 很清楚…… It is likely that … 很可能……

It is important that … 重要的是……

类似的形容词还有：strange;natural;obvious;true;good;wonderful;possible;unlikely;quite;

unusual;certain;evident;worth-while;surprising;interesting;astonishing, etc.例如：It is doubtful whether she will be able to come.It was really astonishing that he refused to talk to you.It is essential that he should be here by the weekend.It seems obvious that we can not go on like this.It is necessary that you（should）master the computer.It is important that a student learn English well.It’s clear that they badly need help.It is likely that a hurricane will arrive soon.需要注意的是，这类主语从句中，谓语动词很多为“（should）＋动词原形”，即要用虚拟语气。

It is +过去分词+从句 It is said that … 据说……

It is reported that … 据报道……

It has been proved that … 已证明…… It must be proved that… 必须指出……

It seems that they will win the game.It makes no difference whether he will attend the meeting or not.It does not matter if I missed my train.It happened that I saw him yesterday.练习
