选择题
___ 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
答案
答案: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。
