这是一个who引导的定语从句,修饰主语people,这个who是不能省略的.
上一句只能说是一个名词片语,但下一句就是一个完整的句子了
who是关系代名词.
看来你要把关系代名词再学一学,看下面:
who Which that
修饰人 修饰事物 可修饰人、事物
i like the boy that is playing basketball.
= I like the boy who is playing basketball.
I have a cell phone that can send e-mail.
= I have a cell phone which can send e-mail
以上的关系代名词(that,who,which)都是当主词
That is the girl.
Everyone likes the girl.
合并成 => That is the girl who (that) everyone likes.
主词 Who Which that
受词 Who(口语）
Whom（文法） which that
例:He is the person whom (who,that) you talked about yesterday.
关系代名词当受词用时,可以省略.
关系代名词当受词,前有介系词时,不可省略
He’s the boy (whom,who,that) we talked about.
=He’s the boy about whom we talked.
当介系词搬到前面来时,只能用whom,不能用who,也不能用that
这样清楚多了吧~
