Question

Gun control is a subject _____ Americans have argued for a long time.

A. of which　　 B. with which　　 C. about which　　 D. into which

 

Answer 1

.C

句意: 枪支控制是美国人争论了很长时间的一个话题。此题考查“介词+关系代词”引导的定语从句。先行词为subject, 带入定语从句后为: Americans have argued about the subject for a long time.由此可知, 先行词在定语从句中作about的宾语, 介词about 提前, 故用关系代词which。
