Question

定语从句中who/whom
在定语从句中,whom和who什么时候可以互换,什么时候不能.请举出相应的sample.

Answer 1

whom是替代陈述句中的宾语,而who是替换主语或宾语用.
It is him who/whom he talked to.
这一句里面,两个词就都可以用,因为这句话里面,who/whom这个位置是宾语,陈述句为 He talked to who/whom.
It is him who took him to the museum.
这一句里面就只可以用who,这句话里面,who的位置是主语,陈述句为 Who took him to the museum.
