Question

___ from space, the earth with water ___70％ of its surface looks like a "blue blanket".

A．Seen ;covered	B．Being seen; covers
C．Seeing; covering	D．Seen; covering

Answer 1

D

本题考查分词短语作宾语补足语和状语。在with复合结构中，宾语补足语covering
70% of its surface和宾语water构成主动关系，故应使用现在分词。seen from space 在句中作状语，和主语the earth构成被动关系，故使用过去分词。
