单选题 with the size of the whole earth, the huge mountains do seem very tiny.
  • A) When compared
  • B) If you compare
  • C) Comparing
  • D) A comparison


【正确答案】 A
【答案解析】[解析] 当从句的主语和主句的主语相同时，从句的主语和连系动词可同时省略。此句是when引导的时间状语从句，在此从句中省略了“the huge mountains are”。例如：If (he is)told the truth that the park is beautiful，he will go to that park with me．(如果告诉他公园很美的事实，他就会和我一起去公园。)
