表语从句精讲及练习（5篇范文）

第一篇：表语从句精讲及练习

新梦圆

1.定义：用作表语的从句叫做表语从句，说明主语是什么或者怎么样。The problem is puzzling.主语 连系动词 形容词作表语

The problem is when we can get a pay rise.主语 连系动词 一个句子作表语---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。解释：

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.在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： My suggestion is that we（should）start early tomorrow.我的建议是我们明天一早就出发。注意：A.表语从句一定要用陈述语序。

False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.B.不可以用if，而用whether 连接表语从句(as if 例外)。

引导宾语从句时可以互换if/whether 位于介词后要用whether

位于句首时要用whether

引导表语从句，主语从句，同位语从句时要用whether

False: The question is if the enemy is marching towards us.Right: The question is whether the enemy is marching towards us.Right: It looked as if he had understood this question C.不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以不一致。

Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.D.that在表语从句中不可以省掉。

表语从句只能置于主句之后，而主句的动词只能是联系动词。

名词性从句在be等系动词后作表语时被称为表语从句，例如： The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西。(how 在表语从句中充当方式状语)// The scissors are not what I need.这把剪刀不是我所需要的。(what 在表语从句中充当

新梦圆

宾语)// What I told him was that I would find him a good play.我告诉他的是我会给他找个好剧本。(what在主语从句中作直接宾语，that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略)// That is what I want to tell you.那就是我想要对你讲的。(what在表语从句中充当直接宾语)// That is why she failed to pass the exam.那就是她考试不及格的原因。(why 在表语从句中充当原因状语)

注意： “That is why...”是常用句型，意为“这就是„„的原因/因此„„”，其中why引导的名词性从句在句中作表语，该句型通常用于针对前面已经说明过的原因进行总结，又如： That is why you see this old woman before you know, Jeanne.珍妮，这就是现在这个老太婆出现在你面前的原因。(前文提到Jeanne对老妇人显得苍老憔悴深感诧异，说话人对她讲述了其中的原因之后，用这一句来进行概括)。// That is why I came.这就是我来的原因。

下面是两个与“That is why...”形式相似的结构，它们与“That is why...”结构之间的关系要能够辨析清楚：

(1)“That is why...”与“That is the reason why...”同义，只不过从语法结构上讲，“That is the reason why...”中why引导的是—个定语从句，将其中的the reason去掉则与“That is why...”结构一样，例如：

That is(the reason)why I cannot agree.这就是我不能同意的理由。

(2)“That is because...”句型中从属连词because引导的名词性从句在此作表语，这也是个常用句型，意为“这就是为什么„„/因为„„”。“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由，“That is why...”则指由于各种原因所造成的后果，例如：

He did not see the film last night.That is because he had to help his little sister with her homework.昨天晚上他没有去看电影，那是因为他得帮助他的妹妹做作业。(第一句话说明结果，第二句话说明原因)

He had seen the film before.That is why he did not see it last night.他以前曾看过那部电影，因此他昨天晚上没有去看。(第一句话说明原因，第二句话说明结果)

［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.(2004)

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?(1999)

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

新梦圆

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.(2003上海春)

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 ____.(2003北京春)

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。

第三篇：表语从句讲解及练习

The Predicative Clause表语从句

在复合句中作表语的从句称作表语从句，位于连系动词（be，seem，remain等）之后。1.that 引导的表语从句

连接词that 仅起连接作用，无意义，在句中不作任何成分，通常不可省略。这种从句往往是对主句主语的内容起进一步解释的作用。

The chance is that one smoker in four will die from smoking.2.whether 引导的表语从句

连接词whether起连接作用，意为“是否、究竟、到底”，（注意：if不能引导表语从句)在句中也不作任何成分。

The question is whether what man will turn up in time.3.what, which, who, whom, whose引导的表语从句

连接代词what, which, who, whom, whose除在句子中起连接作用外，还可在从句中从当主语、表语、定语。

Tom is no longer what he used to be.The question is which of us should come first.The problem is who is really fit for the hard job.The important thing is whose name should be put on the top of the list.4.where, when, why, how引导的表语从句

连接副词where, when, why, how除在句中起连接作用外，在从句中还充当时间、地点、方式、原因状语，本身具有词义。

That’s where I can’t agree with you.This is why Sara was late for the meeting.This is how they overcome the difficulties.My strongest memory is when I attended an American wedding.5.其他连词as if, because, as, as though 引导的表语从句

because引导表语从句通常只用于This/That/It is because„结构中。My anger is because you haven’t written to me for a long time.as if/though引导的表语从句，常置于连系动词look, seem, sound, be, become等后面，常用虚拟语气，表示不存在的动作或状态。

表语从句

一、表语从句的定义：

三、引导表语从句的关联词的种类：

1.可接表语从句的连系动词有be, look, seem, sound, appear等。China is no longer what she used to be.今日的中国不再是过去的中国了。

The question remains whether they will be able to help us.问题还是他们能否帮我们。

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

2.从属连词whether, as, as if / though引导的表语从句 He looked just as he had looked ten years before.他看起来还与十年前一样。

It sounds as if someone is knocking at the door.听起来好像有人在敲门。

3.because, why引导的表语从句

That's because he didn't understand me.那是因为他没有理解我。(That's because...强调原因)

That's why he got angry with me.那正是他对我生气的原因。(That's why...强调结果)what引导的主语从句表示结果或名词reason作主语时，后面的表语从句表示原因时要用that引导，不宜用because。

The reason why I was sad was that he didn't understand me.我难过的原因是他没有理解我。

4.连接代词who, whom, whose, what, which, whoever, whatever, whichever 连接副词 where, when, how, why。如：

四、应注意的问题：

1.连系动词be，appear，seem，look等之后可以跟表语从句。It was because he didn't pass the exam.那是因为他没有通过考试。

It seems to me that we should answer for this.在我看来，我们似乎应该对此事负责。

This is where they once lived.这就是他们曾经住过的地方。

That is why he didn't come here.这就是他为何没到这儿来的原因。2）whether My question is whether he left（or not）.我的问题是他是否离开了。注：if不能引导表语从句。3）that The fact is that he left.事实是他离开了。

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。4）because，as，as if，as though

It's just because he doesn't know her.这是仅仅因为他不认识她。Things are not always as they seem to be.事物并不总是如其表象。He looks as if he's tired.他好像累了。
