主语从句
定义：主语从句是在复合句中做主语的从句。

例

How this happened is not yet clear
It is not important who will go.
注意：由what，whatever，whoever等引导的主语从句一般不能用it作形式主语。
表语从句
表语从句在句中充当表语，位于主句系动词之后。
The question is who can complete the difficult task.
表语从句可用whether引导，也可用as if/though 引导，但不用if引导。
His first question was whether Tom had arrivrd yet.
He looked as if he wanted to remember all the things in the room.
当主句主语是reason时，表语从句的连接词用that而不用because。
区分：

That’s because......+原因
The reason why/for...is/was that...
