现在完成时
现在完成时表示过去发生或已经完成的某一动作对现在造成的影响和结果,强调的是现在的情况,所以它不能直接和表示过去某一时间的时间状语连用,如yesterday, last night, three weeks ago, in 2020等。而一般过去时只表示过去的动作或状态,和现在没有联系, 强调的是过去的情况,它可以和表示过去某一时间的时间状语连用。
例如:
(1)I have been to Beijing.我去过北京。
(现在已经回来了)
(2)I went to Beijing last year.我去年去过北京。
(只是说我去年去过北京,不涉及现在的情况)
(3)She has lived here since 2000.自2000年以来,她一直住在这里。
(她现在还住在这里)
(4)She lived here in 2000.2000年她住在这里。
(不涉及她现在是否还住在这里)
现在完成时的结构为：have/has+过去分词，标志性的词有already, yet, ever since 等，一般疑问句为：Have/Has+主语+过去分词+其他？，肯定回答：Yes, sb have/has，否定回答：No, sb haven’t/hasn’t.
现在完成时
肯定式 否定式
I/You/We/They have finished the work. He/She/It has finished the work. I/You/We/They have not finished the work.
He/She/It has not finished the work.

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。
一般过去式与现在完成时的区别
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, …　
e.g. 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？
They haven't started yet. 他们还没有起身。
We have never heard of it．我们从来没有听说过这件事。
have/has been to, have/has gone to与have/has been in的区别
have been to 曾经去过,现已回来,可接次数 He has been to Beijing 3 times.
他去过北京三次。
have gone to 到某地去了,尚未回来,通常不用第一人称 She’s not here. She has gone to Qingdao.她不在这里，她去了青岛。
have been in/at 在某地呆了多长时间,常接时间段 He has been in London for half a year.
他在伦敦呆了半年。
