whom可以当主语吗？

Question

如题所述

Answer 1

不能。whom这个词既可以用作连词引导名词性从句（宾语从句,主语从句,表语从句以及同位语从句）也可以用作关系代词引导定语从句.
1.引导名词性从句.whom在从句中,只充当宾语.
2.引导定语从句.whom在定语从句中,充当的是宾语.尤其是与介词连用时只能用whom.
whom指人,在定语从句中充当宾语,常可省略.
(1) Mr.Liu is the person (whom) you talked about on the bus.
(2) Mr.Ling is just the boy whom I want to see.
