一般过去时
一般过去时是表示在说话时间以前发生的动作或者状态的动词时态,它是英语时态体系中最重要的时态之一.
1) 一般过去时规则动词的构成形式：
规则动词在其原形后面加-ed:
to work-worked
以字母e结尾的规则动词,只加-d:
to love---loved
对所有人称均无词形变化.
否定式均由did not + 动词原形构成
I / you / he / she / they / we did not work.
疑问式均由 did + 主语 + 动词原形 构成
拼写注意：
情况 变化 例词
动词为单音节,以一个元音字母和一个辅音字母结尾 辅音字母双写,再加-ed Stop-stoppedAdmit-admitted
以y结尾的动词,在y 前为辅音字母时 Y 变为 I ,加 - ed Carry -carriedHurry -hurried
以y 结尾的动词,在y 前为元音字母时 加-ed Obey-obeyedEnjoy---enjoyed
在英语当中有一部分动词的过去式变化形式是不规则的,这类动词被称为不规则动词.总数大概不过200多个,但是使用频率很高.主要分成三类：
1》 第一类不规则动词的三种形式同形,如：
cost cost cost
cut cut cut
hurt hurt hurt
shut shut shut
set set set
注意,有些动词的过去式与过去分词有两中形式,如：
bet bet / betted bet / betted
wed wed / wedded wed / wedded
wet wet / wetted wet / wetted
2》 第二类不规则动词的过去式和过去分词同形,如：
bend bent bent
bring brought brought
catch caught caught

3》 第三类不规则动词的原形、过去式和过去分词都不相同,如：

grow grew grown
ring rang rung
wake woke / waked woken / waked
此外还有少数不规则动词的过去分词与原形相同,如：

一般过去时的功用
1） 表示一个没指明具体时间的过去的行动,如：

We(you / they) have worked. We (you / they) have not worked. Have we (you / they) worked? Have we (you / they) not worked?
紧缩形式
现在完成时的功用
现在完成时可以说成是兼有现在与过去意义的一种复合时态.它与现在有密切联系,如：
------Oh,dear, I’ve forgotten her name.
和现在的联系就是 I don’t remember her name now.
------Fort has gone to Canada.
和现在的联系就是 He is not here. He is in Canada now.
1) 表示延续到现在的动作 （有时是总计做了多少次等）.

She really loves that film. She has seen it eight times.
Tom has lived in Now York all his life.
2) 表示开始与过去而在说话时刻结束的行动,如：

7）与since 连用,since 表示与某一时刻或从句连用,表示“从那一刻到说话时为止”,它总是与完成时连用,如：
She has been here since 6 o’clock.
He hasn’t been himself since the accident. （那次事故后,他从未完全康复）
Since I was a child I have lived in England.
一般过去时与现在完成时的比较
1） 过去时仅仅表示过去,现在完成时还表示与现在的关系,如：

He lost his key.
2) 与现在无关的或者过去很久的历史事件不能用现在完成时

3)如果说明动作有特定的过去时间,就不能用现在完成时,如：

询问某事发生的具体时间或者地点时（when , what time, where）, when , what time, where）, 用一般过去时,如：

比较：
Have you see Ann this moring? ( 说话时仍为上午)
Did you see Ann this morning? ( 说话时为下午)
Jack has lived in London for six years. 还在伦敦住
Jack lived in London for six years. 先不住伦敦了
I have never played golf in my life.
I didn’t play golf when I was on holiday last summer.
现在进行时
现在进行时是由助动词to be 的现在时 + 现在分词构成：
肯定式 否定式 疑问式
I am working.You are working.He (she) is working.We (you,they) are working. I am not working.You are not working.He (she) is not working.We (you,they) are not working. Am I working?Are you working?Is he (she) working?Are we (you,they) working?
现在分词的构成,是在动词原形上加-ing, 但是应该注意：
情况 变化 例词
动词以单个e 结尾 去掉e, 加 ing Love _lovingArgue _ arguing
动词以 -ee结尾 直接加 ing Agree_ agreeingSee _ seeing
动词为单音节：以单一元音字母 + 单一辅音字母结尾 辅音字母双写,再加 ing Hit _ hittingRun _runningStop _ stopping
动词为双音节或者多音节：最后一个音节为重读音节,以单一元音字母 + 单一辅音字母结尾 辅音字母双写,再加 ing Be’gin be’ginningAd’mit ad’mitting

现在进行时的功用
1） 表示说话时正在发生或者进行的动作

Let’s get out. It isn’t raining any more.
2) 表示在现在相对较长一段时间内正在进行的动作,但是说话一刻不一定在做的动作
Have you heard about Tom? He is building his own house.
David is teaching English and learning Chinese in Beijing.
这些动作,在说话时并不一定在发生或进行,而是在包括说话的一刹那在内的一段时间内发生、进行的.
3）表示最近的确定的安排
Ann is coming tomorrow.
Oh, is she? What time is she arriving?
At 10:15.
Are you meeting her at the station?
I can’t. I’m working tomorrow morning.
以上句子也可以用be going to (do) 的形式来表示.但是谈论已确定的安排时候,用现在进行时态显得更加自然,除非受到动词的功能的限制.在此,切不可用will, 如：
Alex is getting married next month. 不能用 will get married.
4) 和always 连用表示某种情绪,可能是厌烦也可能是赞扬,如：
Tom is always going away for weekends.
My husband is always doing homework.
有些动词是表示一种状态而不是动作,一般不用于进行时.例如,我们一般不说 I am knowing, 而说 I know. 常见的这类动词有：
want like hate know see hear believe understand seem
think(相信) suppose remember need love realize mean forget prefer have （拥有）belong
To understand is to accept. 理解就是接受
Do you like Beijing?
Do you see the rainbow?
I remember him very well.
I think I understand what he wants.
一般现在时和现在进行时的比较
一般现在时表示的是一般、重复的动作或者事情
现在进行时表示说话时或说话前后正在发生的动作或事情,如：
Tom plays tennis every Sunday.
Where’s Tom? -------He is playing tennis.
What do you do? 你是干什么工作的?
What are you doing here? 你在这里干什么?
一般现在时是表示经久的情况,而现在进行时表示的是暂时的,如：
My parents live in Shanghai. They have been there for 50 years.
She’s living with some friends until she can find an apartment.
过去进行时
过去进行时的构成形式为：
I / he /she was
We / they / you were + 动词的现在分词
过去进行时的功用
1） 表示在过去某个时间后者某段时间正在进行的动作,如：
When I rang him up, he was having dinner.
This time last year I was living in Shanghai.
What were you doing at 10 o’clock last night?
2) 过去进行时和一般过去时连用,表示在一个动作发生的过程中,发生了另一个动作,如：
It was raining when I got up.
I fell asleep when I was watching television.
3) 过去一般时所说明的动作是已经完成的,而过去进行时不表示正在进行的动作一定会完成,如：
Tom was cooking the dinner.
Tom cooked the dinner.
现在完成进行时
其构成形式如下：
I / we / they have
He / she / it has been + 动词的现在分词
功用如下：
1） 表示一个在过去开始而在最近刚刚结束的行动,如：
Ann is very tired. She has been working hard.
Why are you clothes so dirty? What have you been doing?
2) 表示一个从过去开始但仍在进行的行动,如：

Jack hasn’t been feeling very well recently.
3) 表示一个从过去开始延续到现在,可以包括现在在内的一个阶段内,重复发生的行动,如：
She has been playing tennis since she was eight.
4) 现在完成时强调动作行为的结果、影响,而现在完成进行时只强调动作行为本身,如：
Tom’s hands are very dirty. He has been repairing the car.
The car is going again now. Tom has repaired it.
过去将来时

③用It is/It has been…since…句型,如：
He arrived here two weeks ago.
He has been here for two weeks.

I have ever been to London.我曾去过伦敦.
have gone to表示“去某地了”现在尚未回来,不能与ever, twice等词连用.
He has gone to London.他去伦敦了.
现在完成时与一般过去时的区别
二者都表示“动作已经发生”,区别在于：
（1）现在完成时强调这一动作与现在的关系,即对现在产生的结果、影响等,而一般过去时只表示过去的事实,不表示和现在的关系.
He has learned French for three years.他学法语已三年了.
He learned French for three years.他曾学过三年法语.
Who has taken my bag? I couldn't find it. 谁拿走了我的包?我找不着了!
He cleaned the house yesterday. 他昨天打扫过房间.
The room is clean, for he has cleaned it already. 房间很干净,因为他已经打扫过了.
（2）现在完成时不可与表示过去的时间副词连用,而一般过去时则可以.
He has done some washing yesterday. （F）
He did some washing yesterday. （T）
他昨天洗衣服了.
八、 过去完成时的用法
与现在完成的用法相同,只不过作为衡量基准点的时间点不同,现在完成时以现在作为衡量的基准点,而过去完成时则以过去某个时刻作为基准点.
（1）表示在过去某一时刻或动作之前完成了的动作,即“过去的过去”,常by, before引导的时间状语连用.如：
By the time he was ten, Edison had built a lab for himself.
到爱迪生10岁时,他已给自己建了一个实验室.
He had measured me before I could get in a word.我还没说话,他已把衣服量完了.
We had scarcely reached the school before it began to rain.
我们刚到学校天就下雨了.
（2）表示由过去某一时间开始,一直延续到过去另一时间的动作或状态.常与for和since引导的时间状语相连用.
She said she had worked in that hospital for 20 years.她说她已在那所医院工作20年了.
He said he had taught in the university since 1957.他说自从1957年他就在这所大学任教.（3）叙述过去发生的事情后,反过来又追叙或补述更早以前发生的动作时,常用过去完成时.
I knew nothing about this matter, for I had been away for six month.
对于此事我一无所知,因为我已离开6个月了.
Some people ran into the street. They had heard a loud noise.
有些人跑上了街,他们听到很响的嘈杂声.
九、时态的一致
在一些从句（主要是宾语从句）中谓语动词的时态,常常受主句中谓语动词时态的影响,这叫做时态的一致.
时态的一致通常分以下一些情况下考虑：
1．当主句中的谓语动词是现在时态或将来时态,在这种情况下,从句的谓语动词可以用任何所需时态.如：
I know that Mr. Brown is a good teacher. 我知道布朗先生是一名好老师.
She believes that he was once a solider. 她相信他以前曾是一名士兵.
He will tell us what he is going to do. 他将告诉我们他要干吗.
2．当主句中的谓语动词是过去的某种时态,在这种情况下,从句的谓语动词可以分为下面三种情况：
（1）如果从句的谓语动词所表示的动作与主句的谓语动词所表示的动作同时发生,从句则需要用一般过去时或过去进行时.如：
He was wondering where he could put the box.
他不知道该把这个盒子放在哪里.
The students were talking while the teacher was writing on the blackboard.
老师在黑板上板书时,学生们在说话.
（2）如果从句的谓语动词所表示的动作发生在主语的谓语动作之前,从句则要用过去完成时.如：
The train had left when they got to the station. 当他们到达车站时,火车已经开走了.
He said his father had been dead for twenty years. 他说他父亲已经去世二十年了.
（3）如果从句的谓语动词所表示的动作发生在主语的谓语动作之后,从句则要用过去将来时.如：
She said she would finish the work tonight. 她说过她将于今晚完成这项工作.
We knew that it was going to snow. 我们知道将要下雪了.
3．当从句所说明的为一般真理或客观事实时,无论主句为何时态,从句不受影响,仍用现在时态.
