Question

定语从句中who，whom，whose的用法有什么区别

Answer 1

who和whom都只能指人，而whose通常指人，也可指物。

classroom
whose
door
is
broken
will
soon
be
repaired.
门坏了的教室会很快得到维修。
2、在从句中所作成分不同
①who在从句中做主语。
例句：The
boys
who
are
playing
football
are
from
Class
One.
在踢足球的男生们是一班的。
②whom在定语从句中充当宾语，常可省略。
例句：Mr.
Liu
is
the
person
(whom)you
talked
about
on
the
bus.
刘老师就是那个你在公交车上交谈的人。
③whose在定语从句中做定语。
例句：He
has
a
friend
whose
father
is
a
doctor.

3、用法不同
当关系代词指人且在从句中作宾语时，whom可以替换为who，而whose没有这个用法。
例句：He asked whom（who）
I'd told about his having been away
他问我把他曾离开的消息告诉过谁。
