定语从句中who和whom怎么用

Answer 1

一、什么是定语从句？
用作定语的从句叫做定语从句(attributive clause)。定语从句通常皆置于它所修饰的名词(或代词)之后，这种名词(或代词)叫做先行词(antecedent)。引导宾语从句的关联词为关系代词和关系副词。关系代词在定语从句中可用作主语、宾语、定语等；关系副词在定语从句中只用作状语。如：
The student who answered the question was John. 回答问题的那个学生是约翰。(who answered the question是关系代词who引导的定语从句，用以修饰who先行词student，who在从句中用作主语)
I know the reason why he was so angry. 我知道他这么生气的原由。(why he was so angry是关系副词引导的定语从句，用以修饰why的先行词reason，why在从句中用作原因状语)
二、定语从句的位置。
定语从句一般紧跟其先行词之后。如：
The room which served for studio was bare and dusty. 这个用作工作室的房间空荡荡的，布满灰尘。(关系代词which引导的定语从句紧跟其先行词room之后)
有时亦可与先行词分离。如：
A new master will come tomorrow who will teach you German. 明天要来一位新教师教你们德语了。（关系代词who引导的定语从句与其先行词master分离）
三、关系代词whom和who有什么区别呢？
who和whom都可以在定语从句中指人，区别如下：
一、who为主格，在定语从句里作主语，如：
I have a friend who lives in Paris.
我有一位住在巴黎的朋友。
Do you have a friend who loves the English language?
你有一位懂英语的朋友吗？
二、whom为宾格，在定语从句里作宾语。
I met some friends whom I hadn't seen for ages.
我遇到了很多我多年未见的朋友。

根据情况使用,这里有两个句子,你体会一下：

He is the man to whom I gave the money.
He is the man who/whom/that I gave the money to.
也就是说,当介词提前到连接的关系代词的前面的时候,要用 whom.否则,用三个关系代词的任何一个都可以!
