1、精选优质文档-倾情为你奉上区分一般过去时和现在完成时一相同点：1. 这两中时态中的动作都发生在过去2. 倘若这个动词的过去时是加ed构成，那么这个动词的过去分词和过去时相同 例如：I cleaned(过去时) the room yesterday. I have already cleaned（过去分词） the room.二不同点1. 一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作,说话的侧重点在于陈述一件过去的事情,与现在没有关系。如果你只是要陈述你做了什么，陈述的东西和目前状况没有太大影响，就用；现在完成时表示与现在有关系的发生在过去的动作,到现在为止这个动作可能结束也可

2、能继续下去。它不与表示过去的时间状语连用. 例如：(1.) I washed the plate. “我洗盘子了”（那么洗盘子这个话题基本到此打住，基本没有下文）(1.) I have washed the plate. “我已经洗好盘子了。” （强调做过，完成了。还有可能意思是，既然我已经洗好盘子了，我就该干什么什么了，或者你就应该履行什么承诺之类的。）(2.)I saw the film yesterday. 强调看电影的时间是昨天。(2.) I have seen the flim.我已经看过这部电影了（我现在知道电影的内容/ 我不想在看这电影了，我们选其他的吧。）(3.) I taug

I have learnt English for six years我学英语已经学了六年了（现在还在学，可能还要学下去）2. 常连用的时间状语不同（1）常与一般过去时连用的时间状语yesterday (morning, afternoon,
