四、【语法点拨】 一般过去时和现在完成时的区别
两种时态意义上的区别
1.现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去。但一般过去时表示过去某个时间发生了某事、存在某种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；现在完成时则侧重强调过去的动作对现在造成的影响，也就是用一个过去的动作来描述现在的情况，此时动作发生的时间地点都不是谈论的重点。如:
Jim lost his key on his way to school this morning.吉姆今天早晨在上学的路上丢掉了钥匙。
此句为一般过去时，主要强调丢钥匙的动作发生在过去，至于后来吉姆是否找到了钥匙不强调。
Jim has lost his key. 吉姆的钥匙丢了。
此句用现在完成时，表示吉姆丢了钥匙这件事对现在的影响，即钥匙还没找到，吉姆没办法开门。
2. 现在完成时还可表达某动作从过去到现在进行了多长时间；一般过去时只能告诉我们这件事是过去什么时候发生的。如: Li Lei began to learn English two years ago.李磊两年前开始学英语。
此句强调李磊两年前开始学习英语，现在是否学不知道。
Li Lei has learned English for two years.李磊学英语已经两年了。
此句强调李磊两年前开始学习英语，现在还在学。
3. 现在完成时还可以表达某人做过某事几次了，这也是一般过去时不能表达的。如:
I have seen the film three times.这部电影我看过三次了。
两种时态时间状语上的区别
一般过去时常和表示过去的时间状语连用，如:yesterday,last week,the other day,two years ago等。
现在完成时不和表示过去的时间状语连用，它常用的时间状语有already，yet，ever，never，just，recently，so far，until now，since two days ago，for two months，in the past/last few years等。如:
I received a letter from my friend last week.我上个礼拜收到了我朋友的来信。
He has already finished his work.他已经完成了他的工作。

【语法点拨】 一般过去时和现在完成时的区别
一、两种时态意义上的区别
1.现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去。但一般过去时表示过去某个时间发生了某事、存在某种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；现在完成时则侧重强调过去的动作对现在造成的影响，也就是用一个过去的动作来描述现在的情况，此时动作发生的时间地点都不是谈论的重点。如:
Jim lost his key on his way to school this morning.吉姆今天早晨在上学的路上丢掉了钥匙。
此句为一般过去时，主要强调丢钥匙的动作发生在过去，至于后来吉姆是否找到了钥匙不强调。
Jim has lost his key. 吉姆的钥匙丢了。
此句用现在完成时，表示吉姆丢了钥匙这件事对现在的影响，即钥匙还没找到，吉姆没办法开门。
2. 现在完成时还可表达某动作从过去到现在进行了多长时间；一般过去时只能告诉我们这件事是过去什么时候发生的。如: Li Lei began to learn English two years ago.李磊两年前开始学英语。
此句强调李磊两年前开始学习英语，现在是否学不知道。
Li Lei has learned English for two years.李磊学英语已经两年了。
此句强调李磊两年前开始学习英语，现在还在学。
3. 现在完成时还可以表达某人做过某事几次了，这也是一般过去时不能表达的。如:
I have seen the film three times.这部电影我看过三次了。
二、两种时态时间状语上的区别
一般过去时常和表示过去的时间状语连用，如:yesterday,last week,the other day,two years ago等。
现在完成时不和表示过去的时间状语连用，它常用的时间状语有already，yet，ever，never，just，recently，so far，until now，since two days ago，for two months，in the past/last few years等。如:
I received a letter from my friend last week.我上个礼拜收到了我朋友的来信。
He has already finished his work.他已经完成了他的工作。
