It was the third time that she______to this mountain village to see the children

题目

It was the third time that she______to this mountain village to see the children
划线处为什么要填 had come 而不能是came?

答案

这里要用过去完成时哦……
过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作.
它表示句子中描述的动作发生在“过去的过去”.
句子it was 就表明了 已经是过去了,那么他之前去山村看孩子就是过去的过去了!
