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,

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 “pr ogrammed” to make us do so. (2007上海)

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 i s ____ 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. (2000上海)
