Question

        with the size of the whole earth , the biggest ocean does not seem big at all .

A．Compare	B．When comparing
C．Comparing	D．When compared

Answer 1

D

试题分析：句意,和整个地球的大小相比较，最大的海洋看起来也根本不大了。主语“最大的海洋”与分词动作“比较”之间是一种被动关系，所以应该用过去分词作状语，根据需要，过去分词前面可加上when, while, until, once, though, although, as long as, so long as, unless, as if, as though, even if, even though等词，故选D。
点评：本题考查非谓语动词的正确选用，平时应注意记忆一些基本规则,被动语态主要是看动词和主语是不是被动关系.
