初中英语语法:动词时态专讲

一、概说

动词的时态历来是中考题中考查的重头戏之一。测试重点放在根据特定语言环境区别使用一般现在时,一般过去时和现在完成时;一般现在时(过去时)与现在(过去)进行时;特定的时间状语中时态的使用;结合所获得的语言知识确定正确时态的能力等。综上所述,动词的时态在中考测试中的地位非常重要。因而考生在复习备考中必须对本专题引起足够的重视。

二、各种时态的构成

三、各种时态的用法

◆◆一般现在时

1. 表示经常性或习惯性的动作,常与表示频度的时间状语连用。

时间状语:every day,every other day,sometimes,often,usually,on Sunday …

I leave home for school at 7 _________________ (每天早晨).

The Olympic Games are held ____________________ (每四年).

What do you ____________ (通常) do when you are free on Sunday?

2. 用在客观真理,客观存在,科学事实或格言警句中。

The earth _________________ (绕着……转) the sun.

Shanghai lies in the east of China. 上海

__________中国的东方。

Pride goes before a fall. 骄者必败。

注意:此种用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。

My teacher told us that light _________ (travel) faster than sound.

Didn’t you father tell you that the sun

________ (be) much larger than the moon?

3. 表示按计划表或时间表将要发生的动作,某些动词如come, go, move, stop, leave, finish,

start等,在一般现在时态中可用来表示将来肯定会发生的动作。

The plane _____________ (起飞) at half past eleven tomorrow morning.

The t rain comes at 3 o’clock.火车三点钟到。Class starts in two mimutes. 两分钟后就要上课了。

4. 由when,as soon as,until,before,after

引导的时间状语从句或由if,unless,as long as,once引导的条件状语从句中,一般现在时代替一般将来时。

I’ll help you as soon as I ___________(到达) Beijing tomorrow.

I won’t leave unless yo u __________ (tell) me everything.

◆◆一般过去时

1. 表示在确定的过去时间里所发生的动作或存在的状态。

时间状语有:yesterday,last week,an hour ago,the other day,in 1981等。

Where did you go just now? 刚才你去哪儿了?

2. 表示在过去一段时间内,经常性或习惯性的动作。特别是由would / used to表达的句型,本身表达的就是过去时。常与always,usually,often,sometimes,never等时间状语连用。

When I was a child, I often _______________ (踢足球) in the yard.

He used _____________ (smoke) a lot, but he doesn’t now.

3. 用于追述逝去的人或事,以及在从句中叙述历史事实。

Our teacher told us that Columbus discovered America in 1492.

4. 用于虚拟语气(非真实的过去)。

If I _________ (知道) the truth, I would tell you now.

I wish I __________ (有) a cherry without a stone.

If I _________ (是) a bird, I would fly in the sky.

5. 辨析used to / be used to

1) used to+do:“过去常常”,表示过去习惯性的动作或状态,但如今已不存在。

Mother used not to be so forgetful. 母亲以前没有这么健忘。

Scarf used to take a walk after supper. 斯卡夫过去在晚饭后常常散步。

2) be used to+doing:“对……已感到习惯”,或“习惯于”,to是介词,后需加名词或动名词。

Scarf is used to taking a walk after supper. 斯卡夫现在习惯于在晚饭后散步。

Have you been used to ______________ (住在这里)?

◆◆现在进行时

1. 表示现在(指说话人说话时) 正在发生的事情。在句中往往有now等时间状语或是像Look! / Listen! 等提示词语,有的则是通过上下文暗示某动作正在进行。

We are _____________ (等) you outside the classroom now.

Look! The man _____________ (放) a kite at the square.

The music sounds very familiar. Who ___________ (弹) the piano upstairs?

2. 表示目前一段时间内正在进行的动作,也许此时此刻这个动作并没有进行。

The students are preparing for the examination. 学生们正在作考试________。

Mr. Green is writing another novel these days.格林先生这些天在写另一部小说。(说话时并未在写,只处于写作的状态。)

3. 与always,forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。

You are always ___________ your mind. 你总是改变主意。(表示抱怨或不满)

She is forever thinking of _____________. 她永远都在为他人考虑。(表示赞许)

4. 某些动词的现在进行时可以表示即将发生的动作,这些动词有arrive,come,leave,die等。例如:

They are going to Hong Kong tomorrow. 他们明天要去香港。

◆◆过去进行时

1. 表示过去某一时刻正在进行的动作,这一特定的时间或时刻除了上下文暗示之外,还有时间状语如at that time / moment,at this time yesterday或when / while等引导的状语从句表示。

____________________________ (你正在做什么) at nine o’clock yesterday evening?

It _________________ when they left the station. 他们离开车站的时候,天正下着雨。

While I ______________ (play) on the computer, he knocked at the door.

2. 与always,forever 等词连用,表示反复发生

的动作或持续存在的状态,往往带有说话人的主观色彩。

He was always ringing me up. 他过去老是给我

______________。

My grandfather was always ______________ things. 我祖父总是忘这忘那。

3. come / go / leave / arrive / set out / start 等一些表示趋向动作的动词用过去进行时可表示从过去某一时间看将要发生的动作,一般强调按计划、要求、打算进行的动作。

Mr. Smith said he was leaving for London soon. 史密斯先生说他不久要________________。4. 注意区别:

一般过去时表示在过去某个时间“发生了的动

作”或“存在了的状态”,而过去进行时则强调在过去某一时刻或某一段时间“正在进行的动作”。

Mary wrote a letter to her friend last night. (表明信写完了)

Mary was writing a letter to her friend last night.

(只表明“一直在写”,不清楚“是否写完”,也许信还没有写完)

◆◆现在完成时

1. 一个动作开始于过去,持续到现在(也许还将持续下去)。表示从过去持续到现在并包括现在在内的一段时间的状语有:up to now / till now / until now / so far,in the last / past few days,lately / recently,for+时间段/ since+过去的时间点,ever since / since then / ever since then等。

Great changes have taken place in my hometown ______________________ (在过去的几年里).

He has been busy writing a book ____________ (最近).

She has been a nurse _____________________ (十年).

2. 一件发生在过去的事情对现在产生影响,注意这时说话者的重心在过去的事情对现在产生的影响上。常用的时间状语有already,yet,just,never,before 等。

我以前从没有去过北京。

________________________________________

3. 关于瞬间动词

1) 瞬间动词也叫短暂性动词、终止性动词或非延续性动词,表示动作瞬间完成,可以有现在完成时态,但不能持续一段时间。在完成时中表述这种意思,我们常用相应的延续性动词来代替短暂性动词,有的可变为been+相应的介词/形容词。常见的有:borrow →

buy →

become →

marry →

finish →

die →

begin/start →

fall asleep →

fall ill →

leave →o pen →c lose →

2) 瞬间动词若要接一段时间,需要做一些相应的变换。如:

①He has come to Beijing since last year. (×)

He has been in Beijing since last year. (√)②He has joined the army for three years. (×)

He has served in / been a member of the army for three years. (√)

He joined the army three years ago. (√) He has been a soldier for three years. (√)

It is three years since he joined the army. (√)

3) 但在否定句中,短暂性动词可以与时间段连用。例如:

I haven’t bought the bike for a year.我买这辆自行车还不到一年。

She hasn’t come here for an hour.她来这儿还没有一个小时。

注意:并非有for作为时间状语的句子都用现在完成时。

I worked here for twenty years. 我在这里工作过20年。(我现在已不在这里工作。)

I have worked here for twenty years. 我已经在这里工作20年了。(现在我仍在这里工作。)

Bill says that he will stay in Nanjing for three more days. 比尔说他将要在南京再待三天。

4. 比较一般过去时与现在完成时

1) 过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。

I saw this film yesterday. 我昨天看了这部电影。(强调看的动作发生过了。)

I have seen this film. 这部电影我看过了。(强调对现在的影响,电影的内容已经知道了。)

2) 过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。句子中如有过去时的时间副词如yesterday,last week,in 1986时,不能使用现在完成时,要用过去时。(×)Tom has written a letter to his parents last night.

(√)Tom wrote a letter to his parents last night.

◆◆过去完成时

1. 表示过去的过去

其构成形式是“had +过去分词”。

那时以前那时现在

2. 一件事情发生在过去,而另外一件事情先于它发生(即表示“过去的过去”),那么发生在先的事情的动词须用过去完成时。这个过去的时间可用before

等介词短语构成一个时间状语从句来表示,也可以通过上下文给出暗示。

She __________________ (已经学习) some English before she came to this city.

3. 表示从过去某一时间开始,一直延续到过去的另一时间的动作,常用的时间状语有:by then,by that time,by the end of,before 2012,by the time 等。

By then he had learned English for four years. 截止到那时,他已经____________________。

4. 用在told,said,knew,heard,thought等动词后的宾语从句中。也可用在状语从句中,此时,在过去不同时间发生的两个动作中,发生在先用过去完成时;发生在后用一般过去时。

She said (that) she had never been to Paris. 她说她从来没去过巴黎。

When the police arrived, the thieves had run away. 等到警察来的时候,贼早已经跑了。

5. 过去完成时与现在完成时的主要区别是时间参

照点不用:过去完成时的时间参照点是某个“过去的”时间;现在完成时的时间参照点是“现在”。在使用时,还要注意现在完成时中的很多规则,也适用于过去完成时。

When I got to the cinema, the film

________________ (已经开始) for five minutes.

◆◆一般将来时

1.表示将要发生的动作或存在的状态以及打算、计划或准备要做的事。

其构成形式为: “will / shall+动词原形”或“am / is / are going to+动词原形”。

与一般将来时连用的时间状语有:tomorrow,next week,in five days等。

2. 当主语是第一人称I或we时,问句中一般用shall,表示征求对方的意见:

When and where shall we meet? 我们何时何地见面呢?

3.“am / is / are going to +动词原形”表示计划、打算做某事,表示已决定的,很可能发生的事,或有某种迹象表明要发生的事。

He is going to speak on TV this evening. 他计划今晚到电视台讲话。

Look at the clouds, there is going to be a storm. 看天上的乌云,一场__________要来了。4. 以下几种情况只可用will表将来,而不可用be going to结构。

①表示有礼貌的询问对方是否愿意或表示客气的邀请或命令时。

Will you please __________ (借) me your pencil?

②表示意愿时。

We will help him if he asks us. 如果他要求的话,我们是愿意帮助他的。

③表单纯的将来,与人的主观愿望和判断无关时。

The sun will ___________ (落) at half past seven this evening.

Fish will die __________________ (没有了水).

5. 一般现在时表将来

①下列动词come,go,arrive,leave,start,begin,return的一般现在时表将来。这主要用来表示在时间上已确定或安排好的事情。

The train leaves at six tomorrow morning. 火车明早六点发车。

②在if,as soon as,until,when等引导的状语从句中。

When Bill comes, ask him to wait for me. 比尔来了后,让他等我。

I’ll write to you as soon as

I arrive there. 我一到那儿就给你写信。

6. 现在进行时表将来

意为“意图”、“打算”、“安排”,常用于人。常用词为come,go,start,arrive,leave,stay 等。

I’m leaving tomorrow. 我打算明天动身。

Are you staying here till next week? 你打算在这儿住到下周吗?

◆◆过去将来时

表示在过去看来将要发生的动作或存在的状态,即立足于过去某一时刻,从过去看将来。其构成形式为“would+动词原形”或“was / were going to+动词原形”。与过去将来时态连用的时间状语有:the next day / year,the following week / month等。具体运用时,多用于宾语从句或间接引语中。

He told me that he would visit me if possible. 他说要是可能的话他会来___________的。

Jim asked Lucy if she would buy the new book. 吉姆问露西她是否要_________________。

初中英语动词时态讲解及练习

16种英语时态总结归纳 时态(Tense)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。 1. 一般现在时 用法:A) 表示现在发生的动作、情况、状态和特征。 B) 习惯用语。C) 经常性、习惯性动作。 例:He always helps others. (他总是帮助别人。) D) 客观事实和普遍真理。尤其要注意,如果前后文不是一般现在时,则无法保持主句、从句时态一致。 E) 表示一个按规定、计划或安排要发生的动作,(仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词)可以与表示未来时间的状语搭配使用。常见的用法是:飞机、火车、轮船、汽车等定期定点运行的交通方式。 例:The next train leaves at 3 o'clock this afternoon.(下一趟火车今天下午3点开车。) How often does this shuttle bus run? (这班车多久一趟?) F) 在时间和条件状语从句里经常用一般现在(有时也用现在完成时)表示将来事情。 例:When you have finished the report, I will have waited for about 3 hours.(等你完成这份报告的时候,我就已经等了将近3个小时了。) 2. 现在进行时(be doing) 用法:现在正在进行的动作。 3. 现在完成时(have done) 用法: A) 表示动作到现在为止已经完成或刚刚完成。 例:I bought a new house, but I _________ my old one yet, so at the moment I have two houses. A) didn't sell B) sold C) haven't sold D) would sell 答案是C) haven't sold。 B) 表示从过去某时刻开始,持续到现在的动作或情况,并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点,或for 加一段时间,或by加一个现在时间。 例:Great as Newton was, many of his ideas ___________ today and are being modified by the work of scientists of our time. A) are to challenge C) have been challenged B) may be challenged D) are challenging 全句的意思是:“虽然牛顿是个伟大的人物,但他的许多见解直到今天还在受到挑战,并且被现代科学家的工作所修正。”challenge是及物动词,在本句中应当是被动语态;其动作延续到今天,所以要用现在完成时态。可见答案是C) have been challenged。A) are to challenge和D) are challenging都是主动语态,不可能是答案。B) may be challenged虽然是被动语态,但意思与全句内容不合,所以不对。 C) 表示发生在过去,但对现在仍有影响的动作或情况。通常用点动词,如:arrive, begin, find, give, lose等。 例:John has broken his left leg.(约翰摔断了左腿。) 注意事项 A) 现在完成时是联系过去和现在的纽带。现在完成时和过去时的区别在于:现在完成时强调动作的动态,或受动态的影响,是动态的结果,对现在有影响;过去时只表示过去的某个具体时间里发生的动作,与现在没有联系。

时态 1. 一般现在时 ●形式:do does(单数第三人称) ●意义:一般现在时表示客观的、普遍性的真理以及经常性的事 件。 ●用法: A) 表示现在发生的动作、情况、状态和特征。 B) 经常性、习惯性动作。 e.g.:He always helps others. (他总是帮助别人。) He often goes to the gym. C) 客观事实和普遍真理。尤其要注意,如果前后文不是一般现 在时,则无法保持主句、从句时态一致。 e.g.: The sun rises in the east and sets in the west. Knowledge is power. ●这一用法场合一些表动作频率的时间副词连用: 1). 表示肯定的频率副词:always, frequently, usually, sometimes, generally, occasionally, often etc. 2). 表示否定的频率副词:never, seldom, rarely etc. ?这些副词的位置:在Be动词后,实义动词前。 e.g. He is always late. 2. 一般过去时 ●形式:did ●意义:一般过去时表示在过去的某一特定时间发生和结束的活 动或情况。 ●用法: A) 表示过去某个时间发生的动作或情况。 e.g.: I saw him in the library yesterday morning. (有特定的时间状语) ?y esterday, yesterday evening, last night/month/spring/year, the night before last(前天 晚上),three days/months/years ago, in 1999 etc.。这 些时间状语之前不用加介词。 B) 表示过去习惯性动作,一直持续或反复发生的动作,此时可与表示拼读的时间副词连用。

初中英语八大时态总结

初中英语八大时态总结 一、一般现在时 具体情况(主要用于下面几情况) 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。 在这种情景中,句子常带有表示频率的时间状语:always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually等等,以表示句中的动作或状态是习惯性的、经常性的。例如: They raise ducks as a sideline .他们以养鸭为副业。 It seldom rains here .这儿很少下雨。 2)仅为了描述状态、性质、特征、能力等等。 这里的目的是为了"描述现阶段的动作或状态",其重点"不是强调动作发生的时间、或进行的状态"。例如: He can speak five foreign languages .他能说五种外语。 That is a beautiful city .那是座美丽的城市。 3) 陈述客观事实、客观真理。 顾名思义,客观的情况是"没有时间概念"的;也"不会在意动作进行的状态"。例如: The sun rises in the east .日出东方。 4) 根据英文语法规定,当主句的谓语动词是一般将来时,那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。例如: I'll tell him the news when he comes back. 他回来时,我将告诉他这个消息。 *【用于一般现在时的副词,除了上面提到的一些表示频率的以外,常见的还有:now, today , nowadays等等】 二、一般过去时 具体情况(主要用于下面几情况) 1.主要是用来描述在过去某个时候发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的习惯性动作。 例:I was very thin in my childhood. 2.一般过去时由谓语动词的过去式表示,也就是说动词词末要加-ed(除不规则动词外)。常和一般过去时连用的过去时间状语有:last night (week ,month , year , century , etc.) , yesterday , the day before yesterday , yesterday morning ( afternoon , evening ) , in 1999 , two hours ago ( one week ago , tree years ago , …)等等。 例:Did you meet yesterday? He left just now. 3.使用一般过去时,在某种意义上说就是要强调动作或状态发生或存在于过去的某个时候。"过去"的时间概念有两层意思:一是指"现在某个时间"以前的时间;二是指"说话、写文章的那个时间点"以前的时间 He got his driving license last month. 他上个月拿到了驾照。
