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

A.of which

B.with which

C.about which

D.into which

答案

答案:C

题目分析:考查定语从句,先行词subject,定语从句中argue后面缺少 (with sb. )about/over sth

,所以用about  which 来引导定语从句。句意为:枪支控制是一个美国人争论了很久的问题。选C。

点评:定语从句中的关系代词前面的介词来自于定语从句中的固定搭配或者先行词的搭配,以及句子的意思。
