名词性从句之表语从句专项语法讲义

一、概念： 表语从句是在复合句中作表语的名词性从句。 放在系动词之后,一般结构是―主语+系动词+表语从句‖ 可以接表语从句的连系动词有be, look, remain, seem等 The trouble is that we are short of money.

That is why stone walls are used instead of fences around New England fields. At that time, it seemed as if I couldn't think of the right word anyhow. 二、引导表语从句的词：

从属连词that、whether、as though、 as if because

连接代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等； 连接副词when, where, why, how, however, whenever, wherever等。 1、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。 例如：

The trouble is (that) she has lost his money. The question is whether we need more ice cream. The problem was that it was too valuable for everyday use.

What she couldn‘t understand was that fewer and fewer students showed interest in her lessons. 2、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。 例如

The question is which of us should go. The problem was who could do the work. That's what we should do.

3、由关系副词引导的表语从句。

关系副词 when, where, how, why 除在句子起连接作用外，在从句中还充当时间，地点，方式或原因状语，本身具有词义。 例如：

Go and get your coat. It's where you left it.

I had neither a raincoat nor an umbrella. That‘s why I got wet through. That is how mice ruin many stores of grain every year. That is what he is worried about.

4、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. That's because we never thought of it. It seems as if he didn‘t know the answer.

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）。 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。

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. (what 在表语从句中充当宾语)

What I told him was that I would find him a good play. (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.(what在表语从句中充当直接宾语) That is why she failed to pass the exam. (why 在表语从句中充当原因状语) 【练习题】
