问题 ______ from space, our earth, with water covering 70% of its surface, appears as a "blue planet ".

选项 A、Seen
B、Seeing
C、To be seen
D、Having seen

答案A

解析 本题测试非谓语动词的用法。本句的主语为earth,从外部空间看地球,从地球角度来说只能是被别人看,所以只能使用被动式。本题只有A和C是被动式,A为过去分词,表示完成和被动的含义,C是不定式,不定式表示将来或者目的,所以只有A为正确选项。句子的意思是:“地球表面百分之七十是水,从太空上看像个蓝色的行星。”
