Question

关于whom的使用问题

Whom are u talking about？
whom did you give the book to？
we play with whom？
这三句话中whom是不是都不能换成who？

Answer 1

楼主大可不必把这个东西想得那么复杂，其实很简单：Whom 只能出现在从句里面或是介词（如 to, from, at, of..）后面。
1． Whom 出现在从句里面时，所有用whom的地方都可以用who代替。Whom 这个词只出现在很正式的书面语。口语不用。
2． Whom 在介词（如 to, from, at, of..）后面时，不可替换。
Who told you the story? （主语）
Who is that man over there? （主语补语）
Whom/ Who did you meet at the airport? （宾语）
Whom did you give the book to? （介词宾语）
whom是who的宾格，在现代英语中一般只用于书面体，在口WHO 可以做主语，又可以做宾语
WHOM只能做宾语
例子：1,who are you? 不能是whom are you?
2,This book belongs to whom/who?两者都可以语中通常用who，但在介词后只能用whom。

Answer 2

Whom are u talking about？
whom did you give the book to？
we play with whom？
这三句话中whom都能换成who但第3句是错句
Who are u talking about？
who did you give the book to？
who do we play with ？=with whom do we play？
whom 引导定从或特殊疑问句时位 可以用who代替
但直接在介词后 作介词宾语时 不能用who代替

追问

能多举几个不能用who替代的例子吗，老师？

追答

he is my friend,from whom i learn a lot.

Answer 3

不可以,因为是介词宾语前置,whom其实是介词to的宾语,只能用宾格,即whom
