英语的八种主要时态的用法及比较

一、一般现在时主要用于:

1、表示经常性或习惯性动作。

e.g. It seldom snows here.

2、表示现在的特征或状态。

e.g. He is always ready to help others.

3、普遍真理。

e.g. Action speaks louder than words.

4、剧情图片介绍,背景说明,动作解说。

e.g. (Tom enters the room and sits at the table)

Doctor :What's your trouble, young man?

Tom :I've caught a cold, doctor.

5、时间、条件、让步、方式状语从句表将要发生的动作时。

e.g. Tomorrow we shall go for an outing unless it rains.

与这种时态连用的时间状语常有:always, often, never, seldom, usually, once, a week, now 等。

二、一般过去时主要用于:

1 、表示过去某个时间发生的动作或情况(包括习惯性的动作或状态)

e.g. When did you read the novel?

She often came to help us in those days.

2 、谈到过去的情况时

e.g. I didn't know you were so busy.

3 、谈到已死人的情况时

e.g. Lei Feng was a great communist fighter.

与这个时态连用的时间状语常有:

yesterday, last night, the other day, two months ago, in 1985, then, just now, when, after, as soon as 引导的时间状语从句,表示主句动作开始的时间。

三、现在完成时主要用于:

1 、表示到现在为止这一时期中发生的动作或情况,即多次动作的总和。

e.g. We have learnt four English songs this month.

How many times have you read the novel?

For many days we haven't seen each other.

2 、表示对现在有影响的某一已发生的动作。

e.g. The delegation has left 代表团已经走了(说明现在不在这里)

Look, what you have done. 看你干的事。

与这一时态连用的时间状语有:

already, yet, just, ever, never, by now, so far, recently, by the end of this

month, since, for 短语,连词since 引导的时间状语从句。

一般过去时与现在完成时的区别:

一般过去时:重在说明动作在过去发生时的具体情况(时间、地点、方式、对象、细节等)

。现在完成时:只提起已发生的动作(事实)及其影响,不说明动作发生时的具体情况。cf. Have you had your lunch?

What did you have for lunch?

I have ever been to the Great Wall, and I went there last summer with my

father.

注:现在完成时表达的动作常具有反复性,故下面一句是错的:

Have you seen the six thirty's news program? 应改为:

Did you see the six thirty's news program?

四、现在完成进行时主要用于:表示过去开始的某一动作一直持续到现在,以至延伸到

将来,它强调动作延续时间之长久。

e.g. I've been writing an article.我一直在写一篇文章。(还在写)

cf. I've written an article.我写了一篇文章。(已写完)

It has been raining these days.

这些天一直在下雨。

五、过去完成时

1 、过去完成时是一个相对时态,表示过去的过去,只有在两个过去发生的动作相比较

时才可显示出来。

e.g. As soon as we got to the station, the train had left.

注:

主从句表达的动作紧接时,即两动作发生的时间没有明显时间上的悬殊或空档

时,主从句都可用一般过去时。

e.g. Where did your brother study before he joined the army?

2 、过去完成时可表示截止过去某一时间动作的总或动作的结束。

e.g. By the end of last month. We had reviewed four books

By eight o'clock, he had finished his homework.

与这个时态连用的时间状语常有:

by 1985, by eight o'clock, by then, by the end of last month, by the time when,

when, as soon as, before 等连词引导的时间状语从句,表示主句动作结束的时间。(六)现在进行时主要用于:

1 、表示现在或现阶段正在进行的动作。

e.g. Listen, someone is crying.

What are you doing these days?

2 、代替一般现在时,表示经常性动作或状态,而含有某种感情色彩。

e.g. How are you feeling today? 你今天感觉怎样?(显得亲切)

He is doing well in his lessons. 他的功课很好。(赞扬)

You are always boasting. 你老爱吹牛。(厌烦)

3 、动词go, come, leave, arrive 等表将要发生的动作时。

e.g. They are leaving for Shanghai.

与这种时态连用的时间状语常有: now, these days, recently, this week 等。

七、过去进行时主要用于:

1,表示过去某个时刻或阶段正在进行的动作。

e.g. At that time she was working in a PLA unit. 那时她在解放军某部工作。

What were you doing this time yesterday?

与这个时态连用的时间状语常用:

at nine o'clock, this time last night, these days, at that time 等。

用when 引导的时间状语从句表示主句的动作正在进行的时间。

e.g. When he came in, I was reading a newspaper.

注:

1 、 while 引导时间状语从句叙述过去的动作时,从句常用过去进行时。

e.g. I read a magazine while I was waiting for the bus.

2 、when 用作并列连词,意为“这时”,连接两分句时,第一句多用过去进行时。

e.g. I was reading a newspaper when he came in.

一般过去时与过去进行时的区别:

一般过去时:强调过去某一时间开始或完成的动作。

过去进行时:强调过去某一时间正在进行的动作。

试区别下面两句:

We were building a reservoir last winter. 去年冬天我们在修建一座水库。(可能尚未建成) We built a reservoir last winter. 去年冬天我们修建了一座水库。(已经建成)

八、一般将来时主要用于:

表示将要发生的动作或情况

e.g. Tom will have a bike of his own.

与这个时态连用的时间状语常用:

tonight, tomorrow, the day after tomorrow, next week, in three hours, two days

现在进行时很好记结构be+动词ing。

be由主语来决定,句中常用标志词,

now,look,listen!

一般现在时:肯定句的现在式。

不是三单用原形,是三单就加s,es,

若是否定疑问句,没有be就加个do,

碰到三单加does。如把does加在前,动词就要还原形。

一般过去时:肯定句的过去式。

规则动词加ed,不规则的必须记。

否定形式疑问句,没有be加did。

如把did加在前,动词也要还原形。

特殊的形容词、副词的比较级、最高级:

一分为二有两个,一是远来一是老。

合二为一共三对,坏病两多并两好。

还有一词双意含,只译少来不译小。

比较等级的运用:

原级用在as…as间,比较级用在than前。

and连接两个比较级,说明“越来越怎样”。

三者以上最高级,副词前可不加the。

still,even,和much,比较级前“更怎样”。

还有a lot和a little,也常修饰比较级。

英语中有些动词跟不定式作宾语补足语时省去了to

其口诀是:

一感二听三让四观看。一感:feel 二听:hear、listen to

三让:let、have、make 四观看:observe、see、watch、look at

分开“一段时间”,some time表示“一段时间”;

相聚“在某一时”,sometime表示“在某一时”;

“有时”相聚加s,sometime表示“有时,不时”;

“几次”分开带s,some times表示“几次,次数”。

时间名词前所用介词的速记歌

年月周前要用in,日子前面却不行。

遇到几号要用on,上午下午又是in。

要说某日上下午,用on换in才能行。

午夜黄昏须用at,黎明用它也不错。

at也用在明分前,说“差”可要用上to,

说“过”只用past,多说多练牢牢记,

莫让岁月空蹉跎

英语八种动词时态讲解

英语八种动词时态讲解 1、一般现在时 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。 She doesn't often write to her family, only once a month. 她不常给家里写信,仅一月一封而已。 I cycle to work every day .我每天骑自行车上班。 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。 Changjiang River is one of the longest rivers in the world. 长江是世界上最长的河流之一。 She majors in music .她主修音乐。 All my family love football .我全家人都喜欢足球。 My sister is always ready to help others . 我妹妹总是乐于助人。 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。 The earth goes around the sun .地球绕着太阳转。 Ten minus two is eight.十减二等于八。Light travels faster than sound .光的速度比声音的速度快。 The United States lies by the west coast of the Pacific Ocean. 美国位于太平洋西岸。 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。 If you take the job , they will talk with you in greater details. 如果你接受这份工作,他们将和你谈谈细节。 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。 2、一般过去时 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。这一点在表达意义上与一般现在时相同,只是所在的时间区域不同而已。由于它的主要作用如此,所以在使用一般过去时的句子里常常有一个意义较具体的过去时间状语。这也是它与现在完成时的最大区别之一。 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
