There are 56 students in our class,two thirds of _____ are boys.
of后面填什么?选项分别who,whom,them,which,答案是whom,请问老师,选them行不行?为什么?谢谢
以下用法都正确:
There are 56 students in our class,two thirds of whom are boys. (two thirds of whom are boys 是非限制性定语从句)
There are 56 students in our class,and two thirds of them are boys. (and 连接并列句)
