Question

He has two daughters,____go overseas for further study
A.two of them B.both of whom C.both of which D.all of whom
为什么选，理由

Answer 1

选B .
two of them 指的是三者或者三者以上中的两个,如果就有两个人那么只能用both,所以不考虑A D .定语从句中指代人不用which,要用who或者 whom 从而选B,如果原题变成了He has two daughters,and____go overseas for further study ,那么应该填both of them.因为and连接的是两个句子.
