2）表语从句

1•定义：用作表语的从句叫做表语从句。

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

连接畐U词where，when，how，why.

女口：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。

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。

3）宾语从句

3. 引导宾语从句的关联词有三类：

（1）从属连词that.如：

He told us that he felt ill.他对我们说他感到不舒服。

I know he has returned.我知道他已经回来了。

注：that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下，that不能省略。

〔.Everybody could see what happened and that Tom was frightened. （and连接两个宾语从句，that宾语从句放在and的后面时，that不能省略。）

大家都会看出所发生的事情并知道Tom非常害怕。

2.I know nothing about him except that he is from the south. （that 引导的宾语从句作介词宾语时，that 英语
