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。

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questio n(问题)，trouble(麻烦)，problem(问题)，
result(结果)，chanc e(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 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。

也没雨衣，这是我们淋湿的原因。

大量粮食的。

［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

［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”。

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。

students showed interest in her lessons. (2000上海)
