选择题
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
答案:D
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。
