2021考研英语语法是考生们学习中的重难点，比起繁琐的单词，语法理解在精不在多。英语备考前期，除了需要掌握必背的单词以外，语法学习也不能落下，这是阅读理解题所考查的能力。下面就来跟着启航考研小编一起学习英语语法中的基础概念：关系代词(指人)。

指人的关系代词有：who, whom, whose, that

1.作主语(who, that )

Those who are going to play in the match are to meet at the gate at 1:30 after lunch.

那些参加比赛的人午饭后1：30在大门口集合。

在本句中，先行词是those;关系代词who引导定语从句，同时代替先行词在从句中担任动词are going to play 的主语。

The man who/that is talking with Mr. Wang is a famous doctor.

正在和王先生说话的那个人是一个有名的医生。

在本句中，先行词是the man;关系代词who/that引导定语从句，同时代替先行词在从句中担任动词is talking的主语。

这个复合句可以还原成两个句子：The man is a famous doctor. He is talking with Mr. Wang.

2.作宾语包括作介词宾语(whom, that )。此种情况下的关系代词可以省略

This is just the man (whom/that) I want for the job.这正是我要的做这份工作的人。

在本句中，先行词是the man;关系代词whom/that引导定语从句，同时代替先行词在从句中担任动词want 的宾语。

Is he the manager (whom/that) you are looking for?

他是你在找的那位经理吗?

3.当关系代词紧跟介词作介词宾语时，不能用that，也不能省略

如：The book from which I got a lot of useful information was written by a famous scientist.

我从中得到许多有用信息的那本书是一位著名科学家写的。

Who is the boy with whom you were talking a moment ago.

你刚才和他说话的那个男孩是谁?

I know the young couple from whose house the music is coming.

以上就是2021考研英语语法中有关关系代词(指人)的知识点，代词是英语语法中的基础，对于能否读懂一个长难句起到关键的作用，启航考研建议同学们进行认真的学习和掌握。
