从句我用*表明
宾语从句,例子：I think *(that) I am a good student*.
主语从句,例子：*What he said* is very strange.
定语从句：例子：The child *who wears a red hat* is my friend's little sister.
表语从句,例子：The problem is *that he is too fat to wear the trousers*.
状语从句,分为时间和地点,以及原因,让步状语从句等：*If it rains tommorrow*,I won't go to travel.*When he was a child*,he didn't like to play with friends.*Where he lives*,the sun is shining.
同位语从句也有,但是到高中才是重点,我还是给你个例子：The truth *that the gentleman had been a criminal* surprised every person.
