语从句的一个成分。㈠ 关系代词的用法：① that 指物，有时也指人，在从句中作主语或
宾语。
which 指物，不指人，在从句中作主语或宾语。

TV sets.The books that/which they bought were written by me.EXERCISES:1.我放在桌子上的那件大衣是黑色的。

2 任何想通过考试的人都必须每天努力学习。The girl( who/that/whom )I like is here now.Anyone who wants to pass the exam must work hard.③whom 指人，为who的宾格形式，在句中只作宾语；前面没有介词时，可用who替换使用.eg: He is the worker (who/whom )I talked to yesterday.The doctor with whom she went to the U.S.A last month is very famous.The doctor (whom /who /that)she went to the U.S.A with last month is very famous.
④whose 是 who 的所有格，在从句中作定语，
多指人；也可指物。eg: The boys whose names were called stood up.
I would like a room whose windows faces
towards the sea.注意！在定语从句中常有介词，当介词放在从句末时，who;that;which 可省略，但是，把介词提到关系代词前，只能用介词+which/whom的结构；这时which不能用that代替，whom也不可用who代替。eg: ①The room (that/ which) I live in is very big.=The room __________I live is very big.
=The room_______ I live is very big.in whichwhere②Here are the picture—books (that/which) the
