答案选D.本题考查现在分词做状语.动词orbit和主语the satellite是主动关系,主动关系的话要选现在分词做状语,所以排除B和C；然后看A和D,A是完成式,只有在主句是过去时的时候,状语中的非谓语动词才要用分词的完成式.明白?非谓语动词包括哪些,可以承担哪些功能,你需要专题研究一下.继续努力!
这是带连词的现在分词短语 作状语 相当于 一个 状语从句
答案是 D) orbiting 因为与句子主语是主动关系 故用现在分词
While _orbiting_ the sun,= While _it is orbiting_ the sun
当状语从句 的主语 与句子主语 一致 的情况下 可以用分词短语 代替 状语从句...
