Question

定语从句中以who和whom引导的有什么区别

Answer 1

简单地说就是他们所充当的句子成分是不一样的楼层:
2
who
可以做主语，又可以做宾语
whom只能做宾语
who和whom在定语从句中作关系代词时：
1.who指人，在从句中做主语
(1)
the
boys
who
are
playing
football
are
from
class
one.
(2)
yesterday
i
helped
an
old
man
who
lost
his
way.
2.
whom指人，在定语从句中充当宾语，常可省略。
(1)
mr.
liu
is
the
person
(whom)
you
talked
about
on
the
bus.
(2)
mr.
ling
is
just
the
boy
whom
i
want
to
see.
注意：关系代词whom在口语和非正式语体中常用who代替，可省略

Answer 2

who引导的从句,
先行词作主语
whom是做宾语

Answer 3

引导定语从句的关系代词
who
和
whom
的使用取决于定语从句所修饰的名词或代词（称作“先行词”）在从句里的成分是什么。如果所修饰词在从句里作主语，用
who，作宾语则用
whom。
例：
we
all
like
our
english
teacher
who
has
taught
us
for
ten
years.（此句中的先行词是
our
english
teacher，在从句里是主语，故用
who。）
mr.
jones
is
our
english
teacher
whom
we
all
like
to
talk
to.（此句中的先行词是
our
english
teacher，在从句里是宾语，故用
whom。）

定语从句中先行词是人时用who(作主语、宾语）和whom （作宾语）。介词后只能用whom
如：
1.Do you know te girl who often comes here ? （不能用whom )
你认识经常来这儿的那个女孩吗？
2. He's the boy whom I talked with just now .
=He's the boy who I talked with just now.
= He 's the boy with whom I talked just now . (不能用 who )
他就是刚才和我说话的男孩。
