怎么区别表语从句和同位语从句
His suggestion is that we should stay calm.是表语从句 而 the belief is that the earth is flat 是同位语从句 这要怎么区分?求科普!

Answer 1

系动词后面的从句都是表语从句：The fact is that he came late.
It looks as if he is ill.
That sounds as if it is a bee.
It seems that he has known it.
用来解释、说明前面名词的从句是同位语从句：
I know the fact that he is ill.I have no idea that he has left.I have no idea where he lives.
The question who will be elected mayor of the city is hard to answer.
