Question

【题目】She brought with her three friends, none of __________ I had ever met before.

A. them

B. who

C. whom

D. these

Answer 1

【答案】C

【解析】句意:她带了三个朋友,可是她的这三个朋友我一个都没见过。此题考查非限制性定语从句。先行词 是her three friends ,代人定语从句后为：I had ever met none of her three friends before ,由此可知关系同在定语从句中作介词of的宾语,只能用whom,故答案为C项。A、D两项都不是关系代词，不能引导定语从句. 故排除,“介词+关系代词whom / which”引导定语从句是高考的一大热点。
