who在定语从句中既可以作主语又可以作宾语,那么who在名词性从句中可以作宾语吗? 答：可以. 但这只是在口语（非正式语体中）,用who来代替whom.且在介词后,还是该用whom的. who是主格,whom是宾格.这不要混洧. The man who he is talking with is my teacher.这里用who是口语、非正式的用法.正式用whom The man with whom he is talking is my teacher.这里不可用who I don't know who he is talking with.who引导的就是名词性从句中的宾语从句了.非正式可用who来代替whom.正式用whom.
