什么叫表语从句,状语从句
句子的表语是由一个句子充当的,那么这个充当表语的句子就叫做表语从句
The fact is that he was cheated.
这是个系表结构的句子,the fact是主语,谓语是系表结构,表语是that he was cheated,这个that引导的句子就是表语从句.

宾补和双宾的区别先看下面两个句子
They elected him president.
I sent him a telegram.
第一个句子里面的him是elect的宾语,而president则不是elect的宾语,它是补充说明宾语him的情况.
第二个句子里面的him 依然是send的宾语,而telegram也是send的宾语状语从句可分为:

时间状语从句、 地点状语从句、

原因状语从句、 目的状语从句、

结果状语从句、 条件状语从句、

He felt nervous each time she spoke to him. 每次她和他讲话,他都感到紧张.
