Question

【题目】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

【答案】C

【解析】句意：枪械管制是美国人争论了很长时间的一个话题。本题考查“介词+关系代词”引导的定语从句。先行词为subject，代人定语从句后为：Americans have argued about the subject for a long time，由此可知，先行词在定语从句中作介词about的宾语，about提前，故用关系代词which。argue abouUover sth. 争论某事。
