Question

We went through a period _____ communications were very difficult in the rural areas.

A．which

B．whose

C．in which

D．with which

Answer 1

C

试题分析：考查定语从句：先行词是a period，定语从句中缺少in the period，用in which或where引导定语从句，句意：我们经历了一个阶段，期间在农村交流很难。选C。
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。
