八种时态的具体用法:

一般现在时 表示现阶段经常或习惯发生的动作或存在的状态,或说明主语的特征。① 一般现在时句子中常有的时间状语:often,usually,sometimes,always,every(day等),once/twice,a(week等), on(Sunday等),never,in the(morning等)。如:They go to the Palace Museum once a year.(他们每年去一次故宫)/ They often discuss business in the evening.(他们经常在晚上商谈生意)② 表示客观真理、事实、人的技能或现在的状态时句子里一般不用时间状语。如:The earth turns round the sun.(地球绕着太阳转)/ Light travels faster than sound.(光传播比声音快)③ 表示十分确定会发生(如安排好的事情)或按照时间表进行的事情,用一般现在可以表达将来,句子中可以有将来时间。如:The train for Haikou leaves at 8:00 in the morning.(开往汉口的列车上午8点开车)④ 在时间状语从句中(以when, after, before, while, until, as soon as等引导)和条件状语从句中(以if,unless引导),用一般现在时代替一般将来时,句子可以有将来时间。如:Please ring me up as soon as you arrive in Germany.(你一到德国就给我打电话)/ If it rains tomorrow,we will have to stay at home.(如果明天下雨我们就只好呆在家)⑤ 一般现在时用于倒装句中可以表示正在发生的动作,动词以come, go为主。如:Here comes the bus.(车来了)/ There goes the bell.(铃响了)。⑥ 一般现在时常用于体育比赛的解说或寓言故事中。Now the midfield player catches the ball and he keeps it.⑦ 人的心理活动和感官动作一般用一般现在时而不用现在进行时表达,常见动词有:like, love, hate, dislike, want, wish, hope, think(认为),understand, remember, forget, mean, need, hear, feel, see.如:I think it is going to snow.(我想天要下雪了)/ I really hope you can enjoy your stay here.(我真的希望你愉快地呆在这儿)

一般将来时 表示将来某一时刻或经常发生的动作或状态。①一般将来时的时间状语有:tomorrow,this(afternoon),next(year),one day,now,soon,someday,sometime, in the future, when引导的从句等。② 用will构成的将来时,表示动作与人的主观愿望无关。“shall”用于第一人称,“will”

用于所有人

称。如:I will graduate from this school soon.(我很快就要从这所中学毕业了)/ You will stay alone after I leave.(我走了之后你就要一个人过了)③ “am/is/are going to+动词原形”表示打算或准备要做的事情,或者主观判断即将要发生的事情,而“am/is/are to +动词原形”表示安排或计划中的动作。如:A man told them that the woman was to give birth to the special baby.(有一个人告诉他们那个妇女就会生下那个特别的男孩)/ It’s going to rain soon.(天快要下雨了)④ 表示一个人临时决定要做某事,可以用will表达。如:I will go to the lab to get some chemicals(化学药剂).So please wait until I return.(我要到化学实验室去取些药品,请等我回头)⑤ 现在进行时、一般现在时也可以表示将来。(见相应时态)⑥ shall和will 在口语的一些疑问句中相当于情态动词。Shall一般与第一人称连用,will与第二人称连用。如:Shall we go to the zoo next Saturday?(我们下周六去动物园好吗?)/ Will you please open the door for me?(替我把门打开好吗?)

⑦ “be to +动词原形”表示按照计划将要发生的事情。如:An angel came to tell her that she was to have this special boy.现在进行时 现在进行时表示现在正在进行的动作或是现阶段正发生而此刻不一定在进行的动作。①

现在进行时由“助动词be(am is are)+现在分词”构成。②

过去进行时

过去进行时表示过去某一时刻或某阶段正在进行的动作。①

也可以表示过去一个阶段频繁发生或反复进行的动作,常与always等频度副词连用,以表示赞扬、不满或讨厌等感情色彩。如:He was always borrowing money from me when he lived here.(他住在这里时老向我借钱)

现在完成时

现在完成时表示一个发生在过去的、对现在仍有影响的动作,或表示开始在过去,并且一直延续到现在,甚至还可能延续下去的动作。①在完成时由“助动词have(has)+动词的过去分词”构成。②表示发生在过去的对现在仍有影响的动作时,时间状语有:already, yet, just, once, twice,ever, never,three

瞬间性动词的完成时 → 延续性动词或状态动词的完成时 have(already)gone to… have been in / at … for(two years)has

come to… has been here since(1990)(had)

left…(had)been away from…

arrived…

been in…

died

been dead

begun

been on

ended

been over

bought...had…

borrowed…

kept…

joined…

been in …

或者使用下面这个句型:It is / has been +(多久)+ since + 主语(人)+谓语(过去时)+……+过去时间状语

[注意] 在其它的时态中也存在类似问题,记住,关键是:瞬间动词不能和表达一段时间的状语连用。如:How long may I keep the book?(这本书我能借多久?)(句子中keep取代了borrow)

过去完成时

过去完成时表示过去某一时间或某一动作发生之前已经完成的动作。简言之, 过去完成时所表示的时间是“过去的过去”。①过去完成时由“助动词had+动词的过去分词”构成。②过去完成时时间状语有:by(yesterday), by then, by the end of(last…)或者由when,before等引出状语从句。有时句子中会有already, just, once, ever, never等词语,也会有for… 或since…构成的时间状语。如:They had already finished cleaning the classroom when their teacher came.(当老师来的时候他们已经打扫完了教室)/ The woman had left before he realized she was a cheat.(在他发觉那个妇女是个骗子时她已经走掉了)③过去完成时常用于宾语从句中、after引导的从句中,或者从句是before引导的主句中。如:After I had put on my shoes and hat,I walked into the darkness.(我穿上鞋子戴上帽子走进了黑暗之中)/ He said that he had never seen a kangaroo before.(他说他以前从来没有见过袋鼠)

过去将来时

过去将来时表示在过去预计将要发生的动作或存在的状态。①过去将来时由“助动词should(第一人称)或would(第二、三人称)+动词原形”构成。在美国英语中,过去将来时的助动词一律用“would +动词原形”。②过去将来时常由于宾语从句中,时间状语有:later, soon, the next(day).③在时间状语从句和条件状语从句中不可以使用过去将来时,而应该使用一般过去时。如:He promised that he would pay me a lot if I helped him with the project.(他答应付

给我许多钱如果我帮助他搞那个项目)/ Every time when he was free,he would sit down and read some books.(每次只要他有空他就会坐下来看看书)④表示纯粹的将来时用would或should,表示打算或主观认为的事情用was/were going to(+动词原形)。如:She told me she would be 18 the next month.(她告诉我她下个月就18岁了)/ She told me that she was going to have a walk with her pet dog.(她告诉我她打算带她的宠物狗去散步)⑤过去将来时还可以表示一个过去经常性的动作。如:When it rained in the day, he would bring an umbrella with him.(白天下雨时他会随身带一把雨伞)

(9)现在完成进行时:现在完成进行时指一个从过去就开始一直延续到现在并由可能继续下去的动作,它具有现在完成时和现在进行时双重特征,结构是:“have/has + been +动词的现在分词”。如:I have been swimming in the cold water for about two hours.(我已经在冰冷的水里游了将近两个小时)/ How long have you been waiting here?(你在这里一直等了多久?)21

②.现在完成时的肯定句,其谓语动词如果是瞬间动词,如come, go, begin, join等,则不可与表示一段时间的状语连用。

如:他到此两周了:He has arrived here for two weeks.(×)此时需转换表达方式: ①用ago代替for,并改为一般过去时②用延续性动词代替瞬间动词③用It is/It has been…since…句型,如:

He arrived here two weeks ago.He has been here for two weeks.It is/It has been two weeks since he arrived here.当瞬间动词用于否定句时,则可以与时间段连用。如: I haven’t gone there for six years.(3)表示过去发生过一次或多次的动作已成为某种经验。

I have been to Paris twice.It’s one of the most interesting films I’ve ever seen.比较have been to与have gone to

have been to表示“去过某地”,现在已回来了,可以与ever ,since等词连用。如:

I have ever been to London.have gone to表示“去某地了”现在尚未回来,不能与ever, since等词连用。

He has gone to London.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

与现在完成时的用法相同,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.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.He said he had taught in the university since 1957.(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.Some people ran into the street.They had heard a loud noise.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.She believes that he was once a solider.He will tell us what he is going to do.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.The students were talking while the teacher was writing on the blackboard.(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:

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.We knew that it was going to snow.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。

英语的时态(tense)是一种动词形式,不同的时态用以表示不同的时间与方式。

是表示行为、动作和状态在各种时间条件下的动词形式。因此,当我们说时态结构的时候,指的是相应时态下的动词形式。

英语时态分为16种:一般现在、一般过去、一般将来、过去将来时,以及这四者的进行时、完成时和完成进行时

下面就英语中常见的八种基本时态进行阐述,其它的时态都是在这八种时态的基础上结合而成的。

The plane was arriving at eight.飞机八点到达。过去进行时与一般过去时的区别

一个时间段,而since后只能跟一个具体的时间点。

for two weeks持续两周时间;since Monday自从周一

He has lived here for three years.他在此住了两年了。

I have been here since 1976.自从1976年我就一直在这里。瞬间动词及注意要点:

a.现在完成时的肯定句,其谓语动词如果是瞬间动词,如come, go, begin, join等,则不可与表示一段时间的状语连用。

如:他到此两周了。

He has arrived here for two weeks.(×)

此时需转换表达方式:

① 用ago代替for,并改为一般过去时。

② 用延续性动词代替瞬间动词。

③ 用It is/It has been…since…句型。

所以上面的句子可转换为:

① He arrived here two weeks ago.② He has been here for two weeks.③ It is/ It has been two weeks since he arrived here.b.当瞬间动词用于否定句时,则可以与时间段连用。如:

I haven’t gone there for six years.我六年没去那儿。

(3)强调直到现在为止的生活经历。

I have been to Paris twice.我去过巴黎两次。

It’s one of the most interesting films I’ve ever seen.它是我看过的最有趣的电影之一。

比较have been to与have gone to

have been to表示“去过某地”,现在已回来了,可以与ever ,since等词连用。如:

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, since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

与现在完成时的用法相似,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。

I thought I had seen him before.我原以为以前见过他。

(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 1989.他说自从1989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。

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什么。

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。

The boy was told that the moon travels around the earth.男孩被告知月亮绕着地球转。

Everybody knows that sixty minutes make an hour.人人都知道一小时有六十分钟。

第五篇:初中英语时态用法小结

英语时态用法小结 根据试题统计,动词语法占语法考题中的50%左右,其内容主要包括动词的时态、语态、要掌握英语的时态和语态,必须掌握好英语中的助动词(do, be, have)和时间状语这两个核心问题。现将各考点分别归纳如下。

1.一般现在时

主要用来表示人、事物的现在状况和特点;表示经常或习惯性的动作,句子中常有often, always, from time to time 等时间状语;表示客观规律和永恒真理等。

条件:if, unless, provided If he accepts the job, he will get more money soon.考点三:在make sure(certain), see to it, mind, care, matter +宾语从句中,从句用一般现在时代替一般将来时。

So long as he works hard, I don’t mind when he finishes the

experiment.只要他努力工作,我不介意他什么时候做完试验。
