Question

He had a lot of friends, only a few of ______ were invited to his wedding.

A．whom

B．them

C．which

D．who

Answer 1

A

试题分析：考查定语从句。本题定语从句的先行词是a lot of friends，在后面的定语从句中whom指代先行词作为介词of的宾语。Them不能引导定语从句，which所指代的先行词常常是事物，不能是人；who在句中通常作为主语，不做宾语。故A正确。
点评：定语从句的考查主要就是考查关系词的辨析，关系代词that, which, whose, whom, as， who在句中做主语，宾语，表语或者定语；where, why, when在句中做状语。要分析句子成分，看缺少什么成分，就选用相应的关系词。
