-----Do you know how long the diameter of the Mars?

  -----It’s didmeter is 53%_____that of the earth?

A. as soon as   B. as well as C. as wide as  D. as much as

Answer

C

【解析】

试题分析：句意：你知道火星的直径是多少吗？是地球直径的53%，as...as意为"和……一样"，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as+ adj./ adv. +as。例如： (1)This film is as interesting as that one.这部电影和那部电影一样有趣。as soon as尽快as  wellas 和……一样好as wide as 和……一样宽as much as和……一样多

故选B

考点：考查短语辨析。
