定语从句that表语

　　定语从句that表语

所谓that表语从句就是用一个句子作为表语。它跟在be动词或系动词后面，说明主语是什么或者怎么样的。例如：

a)He has become what he wanted to be.他已经成为了想成为的`那个人。

b)The problem is when we have a meeting. 问题是我们什么时候能举行会谈。

我们说过，宾语从句要用陈述语序。其实，表语从句也是如此。上面的例子如果写The problem is when do we have a meeting就错了。

但是和宾语从句不同的是，宾语从句中的that可以省略，但在表语从句中，这个懒千万不能偷！is suggestion is that we can try to catch the next train. 他建议我们去赶下一班火车。

上面的例句中，引导表语从句的that一定不能省略哦。另外，通常情况下，if和whether可以互换，但是在表语从句中却行不通，一定要用whether。例如：

The question is whether you have enough time to do it.问题在于你是否有足够的时间去做。

千万不能写成the question is if you have enough time to do it
