题目内容
20.________ from the moon,our earth with water ________ seventy percent of its surface looks like a blue sphere.( )A. | Seen; covered | B. | Seeing; covering | ||
C. | Seen; covering | D. | Seeing; covered |
分析 从月球上看,我们70%被水覆盖的地球看起来就像一个巨大的蓝色球体.
解答 答案是C.本题考查分词做状语.第一空是分词做状语;分词做状语时分词的选择是看分词和句子主语之间的关系:分词和句子主语之间是主谓关系(主动关系),用现在分词;分词和句子主语之间是动宾关系(被动关系),用过去分词;题干中see和主语our earth之间是被动关系,所以第一空用过去分词,排除B和D;第二空是with的复合结构,复合结构中分词做宾语补足语的选择是看分词和宾语之间的关系:分词和宾语之间是主谓关系(主动关系),用现在分词;分词和宾语之间是动宾关系(被动关系),用过去分词;动词不定式做宾语补足语时表示动作将要发生.本题with的复合结构中water和cover之间是主动关系,所以选用现在分词,答案选择C.
点评 在非谓语动词的解题中要在掌握其基本用法的基础上关注并积累一些固定用法,结合具体语境做出合理的判断.
