关系代词who,whom,whose,that,which的用法
(1) 关系代词who,whom,whose,that,which的用法
英语中的关系代词有who,whom,whose,that,which,它们是用来引导定语从句的.关系代词既代表定语从句所修饰的词,又在其所引导的从句中承担一个成分,如主语、宾语、表语或定语.如：
This is the man who saved your son.
这就是救了你儿子的那个人.(who在从句中作主语,先行词是man)
The man whom I met yesterday is Jim.
我昨天见到的那个人是吉姆.(whom在从句中作宾语,它的先行词是man)

失去父母的孩子是孤儿.(whose在从句中作定语,它的先行词是child)

他想要个窗户面临大海的房间.(whose在从句中作定语,它的先行词是room)
[1] who,whom和whose
who和whom代表人,在从句中作主语时用who,作宾语时用whom,可省略.但若whom作介词宾语且介词放在其前时,不能省略;如介词位于句末时,可以省略.whose代表某人的,在从句中作定语.如：
The man who insists upon seeing with perfect clearness before he decides,never decides.
坚持看清楚一切后才做决定的人永远也做不了决定.(who作主语)
He is a man whom everybody respects.
他是一个人人都尊敬的人.(whom作宾语,可以省略)
He is a man fromwhom we all should learn.
他是我们大家都应该学习的人.(whom作介词宾语且介词位于其前,不能省略)
(此句也可以是：He is a man (whom) we should all learn from.)

Who,whom和whose可用于非限制性定语从句中,代表某人或某人的,此时不能用that.如：

我姐姐回家住了几天,她是个护士.
[2] which
which代表物,在从句中可作主语或宾语,作宾语时可以省略,但作介词宾语且介词位于其前时不能省略.如：

which可用于非限制性定语从句中,代表物.如：

[3] that
that可以代表事也可代表人,在从句中可以作主语或宾语,作宾语时可省略,但不能用于非限制性定语从句中.代表人时who比that用的多些,代表物时that比which用的多些.如：

(2) 补充说明
下列情况下,定语从句的关系代词只能用that,不能用which或who
[1] 当先行词中有形容词的最高级时.如：

Take the first chance that offers.抓住出现的第一个机会.
(3) 没有先行词的关系代词
如果关系代词引导的从句不是作定语修饰先行词而是充当句子成分,这种关系代词就没有先行词,它只起连接作用.这种关系代词有：what,whatever,whoever,whichever,wherever等.如：
What woke me up was a splashing noise.
把我吵醒的是一阵溅水的声音.(what从句作主语)
I don't know what good they could have done.
