一般过去时
标志:动词过去式
*闭音节:元音字母 a, e, i, o, u 如果发字母本来的音则称为开音节,否则称为
闭音节。
1. 表示过去某时所发生的动作或存在的状态,常与表示过去的时间状语
连用(e.g. yesterday, this morning, just now, a moment ago, in May, last night /
year / week, once upon a time, the other day, before …, when …, in the past
等)。如:

身表示的就是过去常常。如:

*注意区分 sb. used to do sth.(某人过去常常做某事,此处 to 是动词不定
式标志符号)和 sb. be used to sth./doing sth.(某人习惯于某物/做某事,此处
to 是介词)。
3. 代替一般现在时,表示一种婉转、客气、礼貌、商量的语气。此用法

6) This is + 形容词最高级 + that … 这是最…

6. 现在完成时与一般过去时的区别
1) 现在完成时强调对现在的影响和结果,与现在有联系;
而一般过去时强调这个动作发生的时间是在过去,不涉及对现在的影响。
如:
I have seen this film. (我已经看过了这部电影)
I saw this film yesterday. (我是昨天看的这部电影)
2) 现在完成时常与模糊的时间状语连用(如 for, since, so far, ever, never,
just, yet, till/until, up to now, always 等),或者干脆没有时间状语;
而一般过去时常与具体的时间状语连用(如 yesterday, last night, …ago, in
1980, in February 等)。
3) 现在完成时表示持续时一般使用延续性动词(如 live, teach, work,
know 等);
而一般过去时常使用瞬间动词(如 begin, buy, die, marry 等)。如:
He has lived in Hangzhou since last spring.
My grandfather bought the car five years ago.
7. 易错点辨析
1) 考生容易把一些瞬间动词用现在完成时表达,这是错误的。如:
(×) He has died for two years. 他死了两年了。
(√) He has been dead for two years.
(√) He died two years ago.
(×) The film has begun for 10 minutes. 电影开演十分钟了。
(√) The film has been on for 10 minutes.
(√) The film began 10 minutes ago.
(×) She has married for three years. 她结婚有三年了。
(√) She has been married for three years.
(√) She married Mike three years ago.
2) 考生不懂如何区分 have been to 和 have gone to,尽管两者均可后接地
点,但 have been to 表示去过某地(现在已经回来了),have gone to 表示到
某地去了(现在还没回来)。如:
She has been to Paris (three times).
She has gone to Paris.
7
过去完成时
标志:had + 动词的过去分词
1. 表示在过去的某个时间或动作以前已经发生的动作或已经存在的状
态。如:
By the end of last week he had finished the work.
He had left when I arrived.
2. 表示从过去某一时间开始,一直延续到过去另一时间的动作或状态。
如:
We had not seen each other since I left Beijing.
The film had been on for 5 minutes when I got to the cinema.
3. 某些表意向的动词(如 intend, think, plan, expect, hope 等)的过去完
成时表示主语未曾实现的愿望、希望、打算。如:
I had intended to visit you last night, but someone called and I couldn’t get
away.
We had hoped that you would come, but you didn’t.
4. (虚拟语气)在条件状体从句或 wish / would rather 等后面的从句中,
使用过去完成时表示与过去事实相反的主观愿望。如:
The party wouldn’t have been so perfect if you hadn’t come.
I wish I had gone with you to the concert that day.
5. 过去完成时与一般过去时
1) 基本区别:过去完成时表示以过去某时间为起点以前所发生的动作或
存在的状态,即过去完成时强调“过去的过去”,而一般过去时只表示以现在
时间为起点以前所发生的事情或存在的状态。如:
He studied there two years ago.他两年前在那儿学习(离现在两年)
He said he had studied there two years before.他说他两年前在那儿学习过。
(离他说话时两年)
2) 特别注意:两个动作如果按顺序发生,又不强调先后,或者用 then, and,
but 等连词连接时,多用一般过去时。如:
When she saw the mouse, she screamed.
My aunt gave me a hat and I lost it.
8
过去将来时
标志:would + 动词原形
1. 表示从过去某一时间来看将要发生的动作或存在的状态,一般用于主
句为过去时的宾语从句中。如:
He said he would come here next Friday.
I knew that he would help us when we were in trouble.
2. 表示过去的动作习惯或倾向:
The old man would sit on a bench in the quite park for hours without doing
anything.
When I worked on that farm, I would get up at 5 am.
3. 用于虚拟语气中:
If I were you, I would not do that.
If he were here, he would show us how to do it.
4. 过去将来时的其他形式
1) was / were going to + 动词原形。如:
He told us that he was going to attend the meeting.
She said that I was going to be sent to meet her at the railway station.
2) was / were to + 动词原形。如:
The building was to be completed next month.
Li Lei was to arrive soon.
3) was / were about to + 动词原形。如:
We were about to leave there when it began to rain heavily and suddenly.
He was about to have lunch when the bell rang.
