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

試題分析：考查定語從句：先行詞是a period，定語從句中缺少in the period，用in which或where引導定語從句，句意：我們經歷了一個階段，期間在農村交流很難。選C。
點評：定語從句的考查主要就是考查關系詞的辨析，關系代詞that, which, whose, whom, as， who在句中做主語，賓語，表語或者定語；where, why, when在句中做狀語。要分析句子成分，看缺少什么成分，就選用相應的關系詞。
