英语问题We did not disturb him.(until)He finished work.用括号中的词将两个句子连上We did not disturb him.(until)He finished work.用括号中的词将两个句子连上为什么标准答案是We did not disturb him until he had finished work.而不是We had not disturbed him until he finished work.我老觉得应该这两句话连接在一起后应该是说--在他完成工作之前我们没有打扰他.我老觉得我们没有打扰他应该在他完成工作之前.所以我的思维是这两个句子的结合应该和I had not understand the problem until he explained it.一样.所以我才会将答案写成We had not disturbed him until he finished work.

您已经知道过去完成时表示动作发生在过去的过去，那么这句话直翻成：直到他完成了工作我们才去打扰的他。就说明他完成工作发生在前，“打扰”这个动作发生在后，那么完成工作这个动作就是“过去的过去”
过去完成时是发生在过去的过去的事。要比较两个动作谁先发生的，谁先发生谁用过去完成时。
是他先完成工作我们才打扰他。他完成工作发生在打扰他前
而第二句是他解释之前我不理解。不理解是解释前发生的。所以不理解的部分用过去完成时
明白？
disturb 是一个瞬间的动作,不能用have done 这种形式.
先解释 后理解
先完成 后打扰 一样的
