一般过去时现在完成时和过去完成时的区别

现在完成时和一般过去时的区别

现在完成时和一般过去时都表示一个在过去完成的动作，但现在完成时强调的是与现在的关系，如对现在产生的结果或影响等，属于现在时范围，谈论的是现在的情况。而一般过去时只表示动作在过去某一时刻发生，不表示和现在的关系，现在情况可能已发生变化。 Who opened the door? (“谁开的门？”只强调过去开门这一动作，门现在可能已关上。) Who has opened the door? (“谁把门开了？”强调门现在依然还开着。)

◇ 现在完成时不能与明确的过去时间状语连用，如：three days ago, last year, yesterday, last

Sunday, in 2008等等。如句中有以上这些明确的过去时间状语，应用一般过去时。再有，

过去发生的一个动作，

如现在情况已经发生的变化，也应用一般过去时。

☆特别提醒：如果这些过去时间状语前有since，表示“自过去某一时间一直延续到现在”，应用现在完成时。

He finished reading the book the day before yesterday. I put my ruler in my pencil-box, but

现在完成时和过去完成时的区别：总汇。特别好

现在完成时和过去完成时的区别

一、从结构上区别

现在完成时：主语+ have / has + 过去分词（肯定式）

主语+ have / has + not + 过去分词（否定式）

Have / Has + 主语+ 过去分词（疑问式）

过去完成时：主语+ had + 过去分词（肯定式）

主语+had + not + 过去分词（否定式）

Had + 主语+ 过去分词（疑问式）

(二)从时间状语区别

现在完成时: 常用的时间状语包括“now, today, tonight, thi s week, this year, already, yet, just, recently…etc”。

过去完成时: 常用的时间状语包括“by, at, before等构成的短语”。

注意：当表示一段时间，现在完成时和过去完成时都可以用for 或since引导的状语。

例如：Have you had your lunch yet? 你吃午饭了吗？

Yes, I have . I’ve just had it. 是的，我刚吃完。

I have had a clock now. 我现在有一个闹钟了。

Have you already posted the p

现在完成时与一般过去时的区别

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。说话的侧重点只在于陈述一件过去的事情，不强调对“现在”产生的影响。如：

He visited Guilin in 1998.他1998年参观过桂林。(只说明去桂林的时间)

2. 现在完成时表示动作发生在过去，对现在造成了影响或产生了结果。不与确定的过去时间状语连用。如：

Jill has bought a new computer.吉尔买了一台新电脑。（着重点是现在有了一台新电脑）

3. 两种时态的区分

现在完成时与一般过去时的区别 1

（1）一般过去时的谓语动词用过去式，而现在完成时的谓语基本构成是“助动词have /has +过去分词”。如：

（2）一般过去时通常与表示过去的时间状语连用。如：yesterday, last week, two years ago, just now, in 2002等；而现在完成时则常与just, already, ever, never等副词和these days, this week, since..., for...等表示一段时间的状语连用。

重点22 现在完成时、过去完成时和一般过去时态的联系与区别

一般说来，现在完成时表示过去发生的动作对现在产生的影响和结果，着重点在现在。过去完成时表示过去某一时间或动作之前发生的另一动作或状态，即“过去的过去”，必须有一个具体的过去时间或动作来支撑，强调对比。一般过去时只表示过去发生了某一动作，与现在没有联系，并且有明显的时间间隔。 例如：

1.He had learned more than 5,000 English words when he entered the university at the age of 15?

2.Years ago we didn't know this, but recent science has shown that people who don't sleep well soon get ill.

3.The policeman's attention was suddenly caught by a small box which had been placed under the Minister's car.

4.When the old man started to walk back t
