几种时态的区别专题总结大全讲解与练习
1. 一般过去时和现在完成时
1)一般过去时只表示过去发生的动作或状态,常和表过去的时间状语连用,即仅谈过去,不关现在。I wrote a letter this morning. (只说明写了一封信的事实)
2)现在完成时表示过去发生的动作或状态,但和现在有联系,可能刚结束,也可能继续下去。不能和表过去的时间状语连用,译成汉语时可加“已经”。
   I have written a letter this morning. (我已经写了一封信,有继续写第二封的可能,现在还是早上。)
2. 一般过去时和过去进行时
1)一般过去时侧重于说明发生某动作的事实。
   It rained heavily last night.昨晚雨下得很大。(强调下雨,并不强调持续时间)
2)过去进行时侧重于强调某动作的持续过程或表示动作在进行。
   It was raining cats and dogs last night昨晚整整一夜都在下倾盆大雨。(强调没停,一直持续)
3. 现在完成时和现在完成进行时
1) 现在完成时在含义上着重表示动作的结果。

   I have read that book. (已读完)

语法易错题
英语单词记忆
高中英语教材

2)现在完成进行时着重表示动作一直在进行,即动作的延续性。
   I have been reading that book all the morning.( 还没读完)
