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。
