关系代词的用法
一. 关系代词that和which的用法
1.当先行词是不定代词all,much,little, something, everything, anything,nothing, none, the one
时。如：
Do you have anything that you want to say for yourself?
You should hand in all that you have.
(2)当先行词前面被the only, the very, any, few, little, no, all等词修饰时。如：
This is the very person that I’m waiting for.
The only thing that we can do is to give you some money.
(3) 当先行词是形容词最高级或先行词的前面有形容词最高级修饰时。如：
This is the best that has been used against pollution.
This is the most interseting film that I’ve ever seen.
(4) 当先行词是序数词或它前面有序数词修饰时。如：
This train is the las that will go to Suzhou.
What is the first American film that you have seen.
(5)当先行词既有人又有物时。如：
Do you know the things and persons that they are talking about?
(6）当主句的主语是疑问词who或which时。如：
Which is the bike that you lost?
Who is the boy that won the gold medal?
(7) 有两个定语从句时，其中一个关系代词已用which，另外一个应用that。如：
They secretly built up a small factory, which produced things that could cause pollution.
(8)当先行词在主句中作表语，而关系代词也在从句中作表语时。如：
Shanghai is no longer the city that it used to be.
2. 定语从句中，必须用which的情况。
(1)在非限定定语从句中，只用which,不用that。如：
Helen was much kinder to her youngest son than to the others, which, of course, made the
others evny him.
(2) 当动词短语中的介词提前时，只用which，不用that。如：
This is a house in which Lu Xun once lived.
注意：在一些固定搭配的动词短语中，由于动词和介词不可分割，因此不能把介词置于关系词之前。如：
This is the pen (which/that) I’m looking for.
不可以说：This is the pen for which I’m looking.
不可以说：This is the pen for which I’m looking.
二. 关系代词who,whom和whose的用法
当先行词指人，（1）在定语从句中作主语时，用who，不可省略；（2）在定语从句中作宾语时，用whom/that，可以省略；（3）在定于从句中作定语时，用whose,不可省略。如：
She is the girl who lives next door.（先行词在定语从句中作主语）
她就是住在隔壁的女孩。
That’s the girl (whom/that) I teach.（先行词在定语从句中作宾语）
那就是我教的女孩。
This is the scientist whose achievements are well known.（先行词在定语从句中作定语）
这就是那位成绩卓著的科学家。
This is the house whose window broke last night.
=This is the house, the window of which broke last night.
=This is the house of which the window broke last night.
这就是昨晚窗子被打坏的那所房子
