Do you know the boy my mother is talking to?
分析一下这个定语从句，并填出空格处的关系代词。

Answer 1

who/whom/that 皆可。
Do you know the boy whom/who/that my mother is talking to?

当介词后置放在了动词后面，介词不放在that前面时用whom, who ,which, that 都可以。
但是,紧跟在介词后面指人时用:介词＋whom(不能用who),紧跟在介词后面指物时用:介词＋which(不能用that).而且当介词后置同时whom/who/that/which做宾语时，which/whom/that/who还可以省略。

We want to call on the famous scientist (whom/that/who) we have often heard about.

The man with whom she was traveling is her boyfriend.
＝The man (whom/who/that) she was traveling with is her boyfriend.
