The course normally attracts 20 students per year, ________up to half will be from overseas.

A．in which

B．for whom

C．with which

D．of whom

答案

D

解析

考查介词+关系代词引导定语从句。先行词是20 students，是人，不能用which引导，排除A,C；代入定语从句________up to half will be from overseas应是up to half of  the 20 students will be from overseas.所以选D。
