book 3 unit 3 grammar宾语从句表语从句

Grammar 宾语从句与表语从句名词性从句在复合句中起名词作用的从句叫做名词性从句。

名词性从句的作用相当于名词，因此主语从句、表语从句、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。

主语从句：Who will win the match is still unknown.宾语从句：I want to know what he has told you.表语从句：The fact is that we have lost the game.同位语从句：The news that we won the game is exciting.引导名词性从句的连接词可分为三类：引导名词性从句的连接词连接词词义功能that 无词义不作成分，只起连接作用whether/if 是否不作成分，起连接作用what,which whose 分别指什么，哪个作主语、宾语、表语、定语who,whom, 谁，谁的分别作主语、宾语、表语作状语when,where,why,how 分别指什么时候/地方，怎么样，为什么Object Clauses 宾语从句请对应写出句子成分I know him.
