2.5 表语从句的专项习题

一．定义

表语从句就是用一个句子作为表语。位于系动词之后，说明主语身份，特征，属性或状态。

放在系动词之后,一般结构是“主语+系动词+表语从句”

The problem is puzzling.

The problem is when we can get a pay rise.

二、系动词的分类 (4类)

三、引导词

四、注意事项

1.表语从句要用陈述语序。如：

That is where the famous scientist was born.

This is why she is so happy today

2. 不可以用if，而用whether 连接表语从句(as if 例外）

The question is if the enemy is marching towards us. ☓

The question is whether the enemy is marching towards us. √

It looked as if he had understood this question. √

3.时态

表语从句的复合句中，主句时态和从句时态可以不一致。

The question is who will travel with me to Beijing tomorrow.

The question is why he cried yesterday.

4.语气

①主语为advice, order, idea, notion, proposal, suggestion, request等一些表示“建议、劝说、命令”的名词，之后的表语从句中，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。

Our only request is that this should be settled as soon as possible.

我们唯一的请求就是尽快解决这个问题。

②As if/though引导的表语从句时，从句谓语多用虚拟语气,这是因为从句中的情况与事实不相符。

具体来说，如果从句表示与现在事实相反，谓语动词用一般过去式；

如果从句表示与过去事实相反时，谓语动词“had+done”，

如果从句表示将来的可能性不大，用would(might ,could )+动词原形，如：Li Lei is now in a new jacket . he looks as if he were an American boy.

The girl is giving us a vivid description of moon. It seems as if she had been to the moon many times.

但是，如果as if ,as though 引导的表语从句所表示的与事实相符，从句则用陈述语气，如：

The clouds are gathering. It looks as if is going to rain.

5.记住两个句型

①The reason is that…②That is why （because）…如：

The reason is that he didn't catch the bus. 理由是他没有赶上公共汽车。

That is why he came late.那就是他晚的原因。

That is because he didn't catch the bus. 那是因为他没有赶上公共汽车。
