Question

It was a meeting _________importance I did not realize at that time.

A．that

B．which

C．its

D．whose

Answer 1

D

试题分析：考查定语从句：先行词是a meeting，定语从句中缺少定语，用whose修饰importance，句意：这是一个那时我还没有意识到重要性的会议。选D。
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。
