现在完成时

一、现在完成时构成

构成:现在完成时由助动词have + 过去分词构成,助动词have 有人称和数的变化。第三人称单数用has,其余用have.

现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。以study 为例,其否定式、疑问式和简单回答形式如下:

1、现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在的结果或影响。

My daughter has just gone out. 我女儿刚出去。

I’m sure we’ve met before. 我肯定我们以前见过面。

She has arrived. 她到了。

2、表示持续到现在的动作或状态,往往和包括现在在内的表示一段时间的状语连用,如recently, already, just, lately, for…, since…,yet等。如:

I haven’t heard from her these days. 这些日子我没有收到她的信。

We haven’t seen you recently. 最近我们没有见到你。

They have been away for two years. 他们离开已经两年了。

She has been with us since Monday.

①for+时段

②since+过去一个时间点(译为:自从……以来)

③since+时段+ago

④since+从句(过去时)

⑤It is+时段+since+从句(过去时)

Mary has been ill?for three days.

I have lived here?since 1998.

注意:

since和for的区别

since后接时间点,如1993,last term, yesterday, the time I got there

for后接一段时间,表示“长达多久”,如ten years, a while, two days等。3、表示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等,在完成时当中不能和表示一段时间的状语连用,因为它们表示的动作不可能持续。因此,不能说:

He has come here for 2 weeks. ×

The old man has died for 4 months. ×

They have left only for 5 minutes. ×

4、has gone (to),has been (to), has been (in)?的区别

Have/Has gone(to) :去了(现在不在说话现场,可能在路上和已经到)

Where is your father?He has gone to Shanghai.

Have/Has been (to) :去过(已不在去过的地方)

My father has been to Shanghai.

Have/has been in:呆了多久(还在所呆的地方)

My father has been in Shanghai?for two months. /since two months ago. 5、现在完成时不能和表示过去的时间状语连用,如yesterday, last year, in 1976, two days ago, just now, when I came in,但可以和already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never等连用。不能与when连用。

现在完成时往往同表示不确定的过去时间状语连用

例如:

She has already come. 她已经来了。

I haven’t read it yet. 我还没读过这个。

I have met him before. 我从前曾见过他。

Ma Hong has always been a good student. 马红一直是个好学生。

I have often seen him in the street. 我经常在街上看见他。

They have never been to Yan’an. 他们从未去过延安。

I haven't seen him lately. 我近来没看到他。

三、现在完成时的标志

1、现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义:

*?以already, just和yet为标志

He?has already got?her help. 他已得到她的帮助。

He?has just seen?the film. 他刚刚看过这场电影。

He?hasn't come?back?yet. 他还没有回来。

*?以ever和never为标志

This is the best film I?have ever seen. 这是我曾经看过的最好的一部电影。He?has never been?to Beijing. 他从没有到过北京。

*?以动作发生的次数为标志

He says he?has been to?the USA?three times. 他说他已经去过美国三次了。*?以so far(到目前为止)为标+before

He?has got?to Beijing?so far. 到目前为止他已到了北京。

She has passed the exam so far. 到目前为止她已经通过了考试。

2.过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手,进一步学习现在完成时。

①for+时段??②since+过去一个时间点(过去?从句)为标志

四、?瞬间动词

buy, die, join, come,go ,leave, join ……不能直接与for since?连用。要改变动词

buy----have??borrow -----keep

come/arrive/reach/get to-----be in???

go out----be out??leave ----be away

begin-----be on?????finish----be over

open----be open???close -----be closed

die----be dead

1、have代替buy

My brother has had(不能用has bought) this bike for almost four years.

2、用keep或have代替borrow

I have kept(不能用have borrowed) the book for quite a few days.

3、用be替代become

How long has your sister been a teacher?

4、用have a cold代替catch a cold

Tom has had a cold since the day before yesterday.

5、用wear代替put on

6、用“be+形容词”代终止性动词

be+married代marry be+ill代fall (get) ill

be+dead代die be+asleep代fall (get) asleep

be+awake代wake/wake up be+gone代lose,die,sell,leave

be+open代open be closed代close/shut

be+missing(gone,lost)代lose

7、用“be+副词”代终止性动词

be+on代start begin “be+up”代get up

“be+back(to)”代return to, come back to, go back to

“be here (there)”代come(arrive, reach, get) here或go (arrive, reach, get) there

8、用“be+介词短语”代终止性动词

1.“be in/at +地点”代替go to /come to

2.用be in the army?代替join the army

3.“be in/at +地点”代替move to

常用瞬间动词变延续性动词表:

1. have arrived at/in sw. got to/reached sw. come/gone/moved to sw.

→have been in sw./at…相应的介词

2. have come/gone back/returned → have been back

3. have come/gone out →have been out

初中英语过去完成时

英语过去完成时 A 形式 过去完成时由had+过去分词构成,因此无人称变化: 肯定式:I had/I’d worked等 否定式:I had not/hadn’t worked等 疑问式:had I worked?等 否定疑问式:had I not/hadn’t I worked?等 B 用法 1 、过去完成时是与现在完成时相当的过去式。 现在完成时: Ann has just left.If you hurry you’ll catch her. 安刚刚走。如果你快一点,就能追上她。(参见第183节。) 过去完成时: When I arrived Ann had just left. 我到的时候,安刚刚离开。 现在完成时: I’ve lost my case. 我的手提箱丢了。(参见第184节。) 过去完成时: He had lost his case and had to borrow Tom’s pyjamas. 他的手提箱丢了,不得不去向汤姆借睡衣睡裤。 但是,过去完成时不像现在完成时那样限于表达未指明时间的动作,因此可以说: He had left his case on the 4∶40 train. 他把手提箱丢在4点40分的火车上了。 2、现在完成时可以和since/for/always等词连用,表示一个开始于过去并仍在继续或刚刚结束的动作。(参见第186节。)与此同理,过去完成时也可以用来表示在所说的过去某一时刻之前就已开始的动作,这一动作: (a)在该时刻仍然在继续;或 (b)在该时刻停止或刚刚停止。 但应注意,过去完成时还可以用来表示: (c)在所说时刻之前某一时候停止的动作。 (a),(b),(c)这三种类型的例句分别列举如下: (a)Bill was in uniform when I met him.He had been a soldier for tenyears/since he was seventeen,and planned to stay in the army till hewas thirty. 我遇到比尔的时候,他身穿军服。那时他已经当了十年兵了/他 从17岁就当兵,并且还计划在军队里呆到30岁。 Ann had lived in a cottage for sixty years/ever since she was born,andhad no wish to move to a tower block.

现在完成时 一、现在完成时构成 构成:现在完成时由助动词have + 过去分词构成,助动词have 有人称和数的变化。第三人称单数用has,其余用have. 现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。以study 为例,其否定式、疑问式和简单回答形式如下: 1、现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在的结果或影响。 My daughter has just gone out. 我女儿刚出去。 I’m sure we’ve met before. 我肯定我们以前见过面。 She has arrived. 她到了。 2、表示持续到现在的动作或状态,往往和包括现在在内的表示一段时间的状语连用,如recently, already, just, lately, for…, since…,yet等。如: I haven’t heard from her these days. 这些日子我没有收到她的信。 We haven’t seen you recently. 最近我们没有见到你。 They have been away for two years. 他们离开已经两年了。 She has been with us since Monday.

①for+时段 ②since+过去一个时间点(译为:自从……以来) ③since+时段+ago ④since+从句(过去时) ⑤It is+时段+since+从句(过去时) Mary has been ill?for three days. I have lived here?since 1998. 注意: since和for的区别 since后接时间点,如1993,last term, yesterday, the time I got there for后接一段时间,表示“长达多久”,如ten years, a while, two days等。3、表示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等,在完成时当中不能和表示一段时间的状语连用,因为它们表示的动作不可能持续。因此,不能说: He has come here for 2 weeks. × The old man has died for 4 months. × They have left only for 5 minutes. × 4、has gone (to),has been (to), has been (in)?的区别 Have/Has gone(to) :去了(现在不在说话现场,可能在路上和已经到) Where is your father?He has gone to Shanghai. Have/Has been (to) :去过(已不在去过的地方) My father has been to Shanghai. Have/has been in:呆了多久(还在所呆的地方) My father has been in Shanghai?for two months. /since two months ago. 5、现在完成时不能和表示过去的时间状语连用,如yesterday, last year, in 1976, two days ago, just now, when I came in,但可以和already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never等连用。不能与when连用。

初中过去完成时讲解教案资料

过去完成时定义 过去完成时(past perfect)表示在过去某一时间或动作之前已经发生或完成了的动作或状态。它表示句子中描述的动作发生在“过去的过去”。 基本结构 主语+had+过去分词vpp.(done) ①肯定句:主语+had+过去分词. ②否定句:主语+had+not+过去分词. ③一般疑问句:Had+主语+过去分词? 肯定回答:Yes,主语+had. 否定回答:No,主语+had not . ④特殊疑问句:特殊疑问词或词组+一般疑问句(Had+主语+过去分词)? 基本用法 (1)表示在过去某一时刻或动作以前完成了的动作,也可以说过去的时间关于过去的动作。即“过去的过去”。可以用by, before,by the time +从句等介词短语或一个时间状语从句来表示,也可以用一个表示过去的动作来表示,还可能通过上下文来表示。 例如: By nine o’clock last night, we had got 200 pictures from the spaceship. 到昨晚9点钟,我们已经收到200 张飞船发来的图片。 (2)表示由过去的某一时刻开始,一直延续到过去另一时间的动作或状态,常和for, since构成的时间状语连用。 例如: I had been at the bus stop for 20 minutes when a bus finally came. 当车来的时候,我在车站已等了20分钟。 He said he had worked in that factory since 1949. 他说自从1949年以来他就在那家工厂工作。 (3)叙述过去发生的事情,在已叙述了过去发生的事情后,反过来追述或补述以前发生的动作时,常使用过去完成时。 例如: Mr. Smith died yesterday. He had been a good friend of mine. 史密斯先生昨天去世了。他以前是我的好友。 I didn’t know a thing about the verbs, for I had not studied my lesson. 我对动词一无所知,因为我没有好好学习功课。 (4)在含有定语从句的主从复合句中,如果叙述的是过去的事,先发生的动作常用过去完成时。 例如: I returned the book that I had borrowed. 我已归还了我借的书。 She found the key that she had lost. 她丢失的钥匙找到了。 (5)过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句(或间接引语)中,这时从句中的动作发生在主句表示的过去的动作之前。 例如: He said that he had known her well. 他说他很熟悉她。 I thought I had sent the letter a week before. 我认为我一星期前就把信寄出去了。 (6)状语从句:在过去不同时间发生的两个动作中,发生在前,用过去完成时;发生在后,用一般过去时。 如when,before,after,as soon as,till/until引导的 例如: When I woke up, it had already stopped raining. 我醒来时雨已停了。 She didn’t go to bed until she had finished her work. 她直到把工作做完之后才睡觉。

初中英语过去完成时语法精讲

过去完成时语法精讲 一、过去完成时的概念与结构特点 概念:过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作,即“过去的过去(past-in-the-past )”。 ----|-------------------------- |-------------------------------|----------------------------> 那时以前那时现在 构成:过去完成时由“助动词had + 过去分词”构成,其中had 通用于各种人称。 They had already had breakfast before they arrived at the hotel. # She had finished writing the composition by 10 :00 this morning. 二、过去完成时的判断依据 1. 由时间状语来判定 一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有: ( 1 )by + 过去的时间点。如: I had finished reading the novel by nine o'clock last night. ( 2 )by the end of + 过去的时间点。如: We had learned over two thousand English words by the end of last term. (3 )before + 过去的时间点。如: 】 They had planted six hundred trees before last Wednesday. 2. 由“过去的过去”来判定。 过去完成时表示“过去的过去”,是指过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前的用过去完成时,在后的用一般过去时。这种用法常出现在: ( 1 )宾语从句中 当宾语从句的主句为一般过去时,且从句的动作先于主句的动作时,从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如: She said that she had seen the film before. ( 2 )状语从句中 在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去时。如: ] When I got to the station, the train had already left. After he had finished his homework, he went to bed. 注意:before, after 引导的时间状语从句中,由于before 和after 本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句都用一般过去时。如:Where did you study before you came here After he closed the door, he left the classroom. ( 3 )表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…" We had hoped that you would come, but you didn't. 3. 根据上、下文来判定。 【 I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing.

初中英语现在完成时讲解学案

完成时态 1. 用法:①过去发生的动作对现在造成的影响或结果:强调结果 E.g: Yesterday I finished my homework, that’s to say, I have finished my homework now. ②过去已经开始一直持续到现在的动作或状态:强调继续 E.g.:: I have lived here since 1990. 2. 现在完成时的构成have\has+过去分词 3. 现在完成时的四个基本句型 肯定句He has finished the work. 一般疑问句Has he finished the work? 否定句He has not finished the work. 两回答Yes ,he has. No, he hasn’t. 特殊疑问句What has he done? 4. 在下列情形下用现在完成时 (1)九词语 ①already已经肯定句中或句尾 e.g.: I have already found my pen. = I have found my pen already. ②yet已经否定句和疑问句句尾

I have not finished the work yet. Have you bought a computer yet? ③ever曾经句中 e.g.: Have you ever seen pandas? ④never从不句中 e.g.: I have never been to Beijing. ⑤just刚刚句中 e.g.: I have just done my work. ⑥before以前句尾 e.g.: I have never been there before. ⑦so far到目前为止 e.g.: So far he has learnt 200 words. ⑧how long多久 e.g.: How long have you lived here? ⑨how many times多少次 e.g.: How many times has he been to Beijing?
