一般过去式与现在完成时的区别
① 一般过去时只强调过去的动作；现在完成时强调过去的事情对现在的影响。
② 一般过去时通常与表示过去的时间状语连用；现在完成时则不能与表示过去的时间状语连用。
③ 一般过去时单纯表示过去的经历；现在完成时表示过去的动作或状态延续到现在并可能持续下去。
一般过去时的时间状语有：yesterday, last week, … ago, in1980, in October, just now …
现在完成时的时间状语有：for, since, ever, never, just, already, yet, in past years …
共同的时间状语有：this morning, tonight, this summer, before, already, …　
I have seen the film. 我看过这部电影。(我了解这部电影的内容)
I saw the film last month. 我上个月看了这部电影。 (只说明上星期看了这部电影，不涉及现在的情况)
在现在完成时中 ever, never, just, already, yet在用法和意思上的区别
现在完成时表示过去发生或完成的某一动作对现在造成的影响或结果。
如：Have you read that story？你读过那个故事吗？（“读”这一动作发生在过去，对现在造成的影响是：是否知道故事的内容。）
I have bought two apples． 我买了两个苹果。 （“买”这一动作发生在过去，对现在造成的结果是：拥有两个苹果。）
在学习这一概念的同时，还应注意常与现在完成时连用的几个副词：already, just, ever, yet, never等。already, just多用于肯定句中，ever, yet, never多用于疑问句和否定句中。
如：I have already finished my homework．
我已经做完家庭作业了。
He has just had his meal．他刚吃过饭。
Have you ever sung this English song？你曾唱过这首英文歌吗？
