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, how
ever, 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。

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。
