[规则点拨]
在主从复合句中充当表语的从句,叫作表语从句。表语从句位于系动词之后,说明主语是什么或者怎么样。表语从句可由从属连词、连接代词或连接副词来引导。
一、表语从句连接词的用法
1.连接词that/whether
that和whether在表语从句中不作任何成分,that无实义,但whether仍保留“是否”的意义。

麻烦的是她弄丢了他的地址。
My suggestion is that we should tell him.
我的建议是我们应该告诉他。
The question remains whether they will be able to help us.
问题还是他们能否帮我们。
名师点津:if不能引导表语从句。
2.连接代词
引导表语从句的连接代词主要有:who, whom, whose, what, which, whoever, whatever, whichever等。
The problem is who we can get to replace her.
问题是我们能让谁去替代她。

汤姆不再是以前的汤姆了。
3.连接副词
引导表语从句的连接副词主要有:when, where, why, how, whenever, wherever, however等。

那就是我们上次野营的地方。

这就是萨拉上课迟到的原因。
4.其他连接词
另外,because, as if, as though, as, like等连接词也可引导表语从句。

他没吃早饭,那是因为他起床晚了。
It sounds as if someone is knocking at the door.
听起来好像有人在敲门。
二、注意事项
1.why和because引导的表语从句的区别
That's why ...
意为“那是……的原因”,强调结果
That's because ...
意为“那是因为……”,强调原因
I didn't phone her, and that's why she got angry with me.(强调“没打电话”这一结果)
我没有给她打电话,那就是她对我生气的原因。
I didn't phone her, and that's because I got angry with her.(强调“生气”这一原因)
我没有给她打电话,那是因为我生她的气。
2.reason作主语时的表语从句
主语为名词reason时,表语从句中的连接词要用that,而不用because。
The reason for such a serious accident is that the driver was too careless and drank too much.
如此严重的一起事故的原因是司机太粗心、喝酒太多。
3.表语从句中的虚拟语气
在表语从句中,表示间接的命令、要求、请求、建议、决定等,主句中的主语通常是:advice, suggestion, proposal, request, order, idea等,从句谓语用“should+动词原形”,should可以省略,但不可换成would。
My suggestion is that we (should) start early tomorrow.
我的建议是我们明天一早就出发。
4.其他系动词+表语从句
除be以外,可用于表语从句的系动词还有:seem, look, appear, sound, taste, feel, remain等。
