如何区分一般过去时,现在完成时,过去完成时态

一般过去时表示在过去某时发生的动作或存 在的状态。 5 years ago now 2. We have learned English for 5 years. 现在完成时表示的动作发生在 过去,但侧重对 现在产生的结果或造成的影响,与现在有关。 其结构为:“助动词 have

(has)+过去分词” 5 years ago have learned now

过去完成时的概念与结构特点:

过去完成时
由“过去的过去”来判定。 过去完成时表示“过去的过去”,先发生的动作用过去完 成时,后发生的动作用一般过去时。 first When I got to the station, the train had already left. first
