() from space,the earth,with water () seventy percent of its surface ,looks like a blue ball.A.Seen;coveredB.Seen;coveringC.Seeing;coveredD.Seeing;covering
B.Seen;covering
seen from space 是过去分词短语作状语,
与其逻辑主语the earth 构成被动关系,故用过去分词seen.
"with +宾语+ 宾补"作原因状语,由于water 与cover 是主动关系,故用现在分词形式covering .
句意:从太空上看,地球,由于其表面的70%被水覆盖着,看起来象一个兰色的球体.
