表语从句
定义：用作表语的从句叫表语从句，它是名词性从句之一。
引导表语从句的连接词有：
从属连词：that / whether /as if /as though (if不引导表语从句)
连接代词：who / whom / whose / which/ what
连接副词：when / where / why / how
What I want to say is that I’m sorry.
2.The fact is that I earned my passage by working as an unpaid hand.
由从属连词 that 引导的表语从句
that在从句中不充当任何成分，本身也没有任何意义。只是起连接作用。注：that 在引导表语从句时不能省略。
由从属连词 whether引导的表语从句
whether 在句子中不充当任何成分，具有“是否”的意义，此时不能用if，因为if不能引导表语从句。
