求指教一道考研改错题~
Mercury's velocity is so much greater than the Earth's that it completes more than four revolutions around the Sun in the time that takes the Earth to complete one.正确答案是把time后面的that改成it.

Answer 1

如果使用It的话,time就成为了下一句话的主语,Time takes the Earth to complete one.这在逻辑上是错误的,time怎么会主动去执行后面的动作呢?it作为代词,代指“ Mercury completes more than four revolutions around the Sun in the time ”或是改成一个定语从句,Mercury's velocity is so much greater than the Earth's that it completes more than four revolutions around the Sun in the time,which takes the Earth to complete one.
