学员疑问：这个介词不知如何选？
1. 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
老师解答：把先行词20students 代入定语从句，将定语从句还原成完整的句子就可以up to half of 20 students will be from overseas。就可以写成of whom up to half will be from overseas.
点评分析：定语从句引导词的选择，可以先划出定语从句，再将先行词代入定语从句，将从句还原成完整的句子，根据定语从句的句意或者其中的固定搭配，来补全介词；最后可以把介词+关系代词提到定语从句前面。
