_____ on a clear day, far from the city

问题选择题

_____ on a clear day, far from the city crowds, the mountains gave him a sense of peace.

A．If walking

B．While walking

C．Walking

D．When he was walking

答案

答案：D

题目分析:考查非谓语动词和状语从句。A、B、C三项均是现在分词，表示句子主语和动词之间是主动关系，而此句主语the mountains不是非谓语的逻辑主语，故排除非谓语动词用法。D项为时间状语从句，选D。句意：在一个晴朗的日子里，当他远离城市拥挤的人群时，大山给了他一种宁静的感觉。
