当指代人的关系代词在定语从句中做宾语时,既可以用who ,也可以用 whom,但是如果关系代词前有介词时,只能用whom. I don't know the girl who/whom/that our teacher is talking with. There are twenty girls in our class,three of whom are good at football. The girl with whom I went to see my friend yesterday is Mary.
who既可以作主格，又可以作宾格。一般情况下，都可以用who.但是当介词前置时，只能用whom. 例如： I don't know the girl who/whom our teacher is talking with. I don't know the girl with whom our teacher is talking.
whom作宾语 who都可以 (2)好像除外 用who就不会错 比如 (1)he is the boy whom i played with yesterday.也可以说成 (2)he is the boy with whom i played yesterday.
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
