______ with the size of the whole earth, the highest mountain does not seem high at all.

A. When compared                 B. While comparing

C. Compare                                     D. Comparing

题目解答

答案

A

解析

此题考查非谓语动词的用法。句子的主语是the highest mountain，与compare之间是被动关系，因此使用过去分词作状语。选项A中的when compared是when it is compared的省略形式，符合题意。
