一般过去时与现在完成时区别专题

一、前言:

初一下学期同学们学习了一般过去时态的相关知识,即将到来的初二上学期英语学习中,现在完成时是重要的学习内容。本文通过对比一般过去时和现在完成时,对现在完成时进行初步讲解,希望使同学们读新学期的学习有所准备。

二、现在完成时

1. 现在完成时的构成

现在完成时是由助动词have (has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词,说明句子的意义。

2. 现在完成时的用法

现在完成时表示过去某时发生的行为对主语目前产生的影响。即用过去发生的某个行为来说明现在的某种情况。

We are good friends.(现在的情况)

I knew him in 1997.(过去的动作)

We have known each other since 1997.

(现在完成时把过去的动作和现在联系起来并着眼于现在)

(1)表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如:

-Have you had lunch yet?

-Yes, I have. I've just had it.

你(已经)吃午饭了吗?我刚刚吃过。(现在我不饿了)

(2)表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。常带有for和since等表示一段时间的状语。

如:He has taught here since 1981

他自1981年就在这儿教书。(可能还要继续教)

I haven't seen her for four years.

我有四年没见到她了。

(3)表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”,常带有twice,ever, never,three times等时间状语。

如:I have been to Beijing twice.我去过北京二次。

3.现在完成时的时间状语

(1)现在完成时属于现在时范围,故不能和过去的时间状语连用。如:yesterday,last Sunday,in1990,three years ago等。但是,在强调动作产生的后果和影响时,可以和一些表示不确定的时间状语连用。

a. 用副词already和yet。already一般用于肯定句中,yet一般用于否定句和疑问句中。

如:We have already finished our homework.我们已完成作业了。

They haven't finished their homework yet.他们还没有完成作业。

b.用ever 和never。多用于否定或疑问句中,表示“曾经”或“从未“等。

如:-Have you ever been to the Great Wall? 你曾经去过长城吗?

-I have never been to the Great Wall.我从未去过长城。

c.用表示到说话为止的过去时间状语,如just, before, up to now, the past few years等。

例如:I have seen her before, but I can not remember where.

我以前见过她,但记不起在哪里见过。

He has been there three times the last few days.

近几天他去过那里三次了。

d.用包括“现在”在内的时间状语,如:now, today, this morning (month, year, term)等。

例如:-Have you met him today? -No, I haven't.

今天你见过他吗?我没有。

How many times have you been there this year?

今年你去过那里多少次?

(2)现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始,一直持续到现在。如:I haven't seen him for two years.但是,像come,arrive,buy等终止性动词不能与表示“一段时间”的状语连用。要用,必须改为“be(在)”等延续性动词来表述。现归纳总结一下由非延续性动词到延续性动词的转换:

arrive→be here begin(start)→be on

die→be dead come back→be back

leave →be away fall ill(sick,asleep)→be ill(sick,asleep)

get up→be up go out→be out

finish →be over put on→wear 或be on

open→be open join→be in或be a member of…

close→be closed go to school→be a student

borrow→keep buy→have

catch(a cold)→ have(a cold)get to know →know

begin to study→study come to work→work等

如:He has been a soldier for three years.他参军三年了。

His father has been dead for two years.他父亲去世二年了。

The film has been on for ten minutes.电影已开始十分钟了。

We have studied English for three years. 我们(开始)学英语已三年了。

4.几点注意事项

(1)have been(to)与have gone( to)的区别:have been(to)表示“去过某地(现在已经回来了)”,可用于各人称;have gone(to)表示“去某地了(说话时某人不在当地)”,常用于第三人称,前者可与once ,never, several times 等连用,后者则不能。如:They have been to Beijing twice.他们去过北京两次。

He has gone to Beijing .他去北京了。

(2)如单纯表示一段时间,或强调一段时间,虽有since一词,也不必用完成时。

如:It is two years since his father died.

=His father has been dead for two years.他父亲去世已有两年了。

(3)终止性动词现在完成时的否定式,已变成一种可以延续的状态,因此可以和表示一段时间的状语连用。

如:I haven't left here since 1997.自从1997年以来,我一直没有离开过这儿。

(4) 表示行为或状态从过去一直持续到现在时,用现在完成时,要加表示一段时间的时间状语时,常用for+一段时间, since+时间点。

I have lived here since my childhood.我从小就一直住在这里。

I have lived here for 10 years. 我在这已经住了10年了。

(5) 在提问现在完成时的时间状语时通常用how long

How long have you lived here?

注意:在表示某一行为状态持续多长时间时,根据终止时间的不同,时态使用是不一样的。如:

I lived here for a week last summer.去年夏天我在这里住了一周。

I have lived here for a week by now. 到现在为止,我已经在这里住了一周。

I will live here for a week next year.明年我会在这里住一周。

二、现在完成时与一般过去时的区别

现在完成时用来表示之前已发生或完成的动作或状态,其结果的确和现在有联系。动作或状态发生在过去,但它的影响现在还存在;而一般过去时表示过去的事实,不表示和现在的关系。

I have just been to London. I went there last month. 我刚去过伦敦,是上个月去的。

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。

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。

一般过去时的时间状语:

yesterday, last week,…ago, in1980, in October, just now, 具体的时间状语

共同的时间状语:

this morning, tonight, this April, now, once,before, already, recently,lately

现在完成时的时间状语

for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always,

3.现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know.

过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。

举例:

I saw this film yesterday. (强调看的动作发生过了。)

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

Why did you get up so early? (强调起床的动作已发生过了。)

Who hasn't handed in his paper? (强调有卷子,可能为不公平竞争。)

She has returned from Paris. 她已从巴黎回来了。

She returned yesterday.她是昨天回来了。

He has been in the League for three years. (在团内的状态可延续)

He has been a League member for three years. (是团员的状态可持续)

He joined the League three years ago. ( 三年前入团,joined为短暂行为。)

I have finished my homework now.

---Will somebody go and get Dr. White?

---He's already been sent for.

句子中如有过去时的时间副词(如yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。

(错)Tom has written a letter to his parents last night.

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

现在完成时的用法讲解1

现在完成时的讲解 对所学时态的回顾,引入现在完成时 通过数轴来概括讲解所学的四个时态:一般现在时、现在进行时、一般过去时、一般将来时。 (导入)有时候,这4种时态还不能满足我们表达的需要。比如:表示“某人过去曾经做过某事”或者“某人做某事多久”,以上五种时态就派不上用场了。这时,我们可以用一种新的时态——现在完成时表示。同样也用数轴来表示一下。 taught will teech -------- ---------- -------- --------- ---------- ? —过去时now 垠时 is teaching fit在发生) -------- ---------- -------- --------- ---------- ? DOW 枉进行时 past two years (has taught) ------ --------------------------------------------- Two years ago 现在完成时now 一现在完成时的构成:主语+ have/has +过去分词 (过去分词:规则动词的过去分词构成与动词过去式相同;不规则动词需要特殊记忆。 eg」_ have taught English in this school since 1999. 二、否定式:主语+ haven' t/hasn' t +过去分词。 疑问式:Have /Has +主语+过去分词? 简略答语:Yes,主语+ have/has.肯定) No,主语+ haven' t/hasn' t.(否定) —Have you finished your work? —Yes,l have. 三现在完成时的含义之一表示过去发生或已经完成的动作对现在造成的影响或结果, 常与already/yet,just,never/ever, before, so far等连用。这些标志词可以表达这种含义 1.already意为“已经”,通常用于肯定句中,可放在助动词之后,过去分词之前,也可以放在句末。实例: 1)rve already read this book.我已经读过这本书了。 (“读”这一动作发生在过去,对现在造成的影响是“知道书中的内容”。) 2)rve washed my clothes already 我已经洗了衣服。 (洗衣服的动作已完成,其结果是“衣服冼干净了”。)

现在完成时的用法解析

Lead in 一般过去时导入:一般过去时的概念 一般过去时表示过去某个时间发生的动作或存在的状态。 I lost my pen.(过去时) I have lost my pen.(现在完成时) 过去时一般表示过去所发生的动作或存在的状态。“我把笔丢了”,说话人只是想告诉对方在过去的某一个时间里他的笔丢了,仅此而已。(仅仅是在陈诉过去的一个事实,与现在没有关系) New lesson 一.现在完成时的构成: 助动词have/has(not) +动词过去分词 She has turned on the lights. 肯定式:have/ has+过去分词 否定式:haven’t/hasn’t+过去分词 疑问式:把have/has 提到主语前面 肯定回答:Yes,…have/has 否定回答:No,…..haven’t/hasn’t 二.用法 1.表示过去发生的动作对现在造成的影响或结果. 例如:She has gone. 她走了. She went in the past.(She is not here

now.) I have just cleaned my hands. 我刚洗过手。(“洗手”是发生在过去的动作,对现在造成的结果是“手干净了”) I have closed the door. (The door is close now.) She has turned on the lights. (The lights are on now.) He has written his name on the blackboard. (The name is on the blackboard now.) Mother has cooked the dinner. (We can have dinner now.) You have seen the film. (You know what the film is about.) We have cleaned the classroom. (The classroom is clean now.) 2. 表示动作发生在过去,并且一直延续到现在,甚至还可能继续延续下去。这时常和since所引导的短语或从句或for引导的短语连用(for有时可以省去)。以及so far, by now, these days, in the last/past … years/days…等连用。 I have lived here for over ten years. (表示他现在还在这里居住,并且还有可能继续住下去)比较:I lived here ten years ago.(仅仅说明了他十年前在这里记住过的事实,不代表现在他还住在这里) He has studied here since 2006. 都用How long 提问,例: We have learned English for three years. We have learned English since three years ago.

英语现在完成时的用法大全附解析百度文库 一、初中英语现在完成时 1.Nancy for five years. A. was dying B. has died C. died D. has been dead 【答案】 D 【解析】【分析】句意:南西去世五年了。A. was dying过去进行时态;B. has died现在完成时态;C. died一般过去时态; D. has been dead现在完成时态。句子强调的是过去开始的动作或状态一直延续到现在,句子用现在完成时态;die是一个非延续性动词,不能与表示一段时间的状语for…连用,用成be dead。故选D。 【点评】本题考查时态辨析。某人去世了多少年就用延续性动词的现在完成时,has been dead。 2.Mike used to be a top student, but he behind since he lost himself in computer games. A. fell B. has fallen C. was D. has been 【答案】 D 【解析】【分析】句意为“Mike过去是尖子生,但自从迷上电子游戏以来成绩落后了”。由since可知but后的主句用现在完成时,瞬间动词fall不能和since引导的时间状语从句连用,故用延续性动词be。故选D。 【点评】本题考查现在完成时中非延续性动词和延续性动词的转换。 3.— Hobo and Eddie the cinema to watch the film Zootopia. — Oh, that's why I can't find them now. A. have gone to B. have been to C. has gone to D. has been to 【答案】 A 【解析】【分析】考查主谓一致。句意:——侯博和埃迪去了电影院看电影《疯狂动物城》。——哦,这就是为什么我现在找不到他们的原因。have gone to去了;been to去过。Hobo and Eddie作主语,谓语动词要用复数形式。所以选A。 4.—What _______ you just now? —Don't worry.

现在完成时的用法 一、概念 现在完成时主要强调过去发生的动作对现在造成的影响,或过去发生的动作还未结束,一直持续到现在或将来,重点在于对现在的影响。 二、理解: 现在完成时用来表示之前已发生或完成的动作或状态,其结果的确和现在有联系。动作或状态发生在过去但它的影响现在还存在;也可表示持续到现在的动作或状态。 四、基本用法: 1.已完成用法(影响性用法)。该用法的现在完成时表示一个过去发生的动作 在过去已经完成,并且这个过去发生并完成的动作对现在有影响或结果,同时 说话强调的或感兴趣的就是这个影响或结果。如:

He has left the city. 他已离开这个城市。(结果。如:他不在这个城市) Someone has broken the window. 有人把窗户打破了。(结果。如:窗户仍破着) Have you seen my bag? 你看到我的手提包了吗?(结果。如:你知道它在哪里吗?) I have bought two apples.我买了两个苹果。(“买”这一动作发生在过去,对现在造成的结果是:拥有两个苹果。) 【注】现在完成时“完成用法”的特点是动作不延续,因此,该时态只能与表示不定的过去时间状语(如:already,just, yet,before,recently等)、频度时间状语(如:never,ever,once等)、包括现在时刻在内的时间状语(如:this morning/month /year..., today等)连用。already,just多用于肯定句中,ever,yet,never多用于疑问句和否定句中。 如:I have already finished my homework.我已经做完家庭作业了。 He has just had his meal.他刚吃过饭。 Have you ever sung this English song?你曾唱过这首英文歌吗? They haven't started yet.他们还没有动身。 We have never heard of it.我们从来没有听说过这件事。 2.未完成用法(持续性用法)。如:该用法的现在完成时表示一个过去发生的动作并未在过去完成,而是一直持续到现在,并且有可能继续下去(也可能到此结束)。此种用法的句中常需一个表示一段时间的状语(由since或for引导),或表示与现在时刻相连的时间状语(如:up to now,so far到目前为止)等。如: He has lived here since 1971. 自从1971年以来,他一直住在这儿。 (动作起始于1971年,一直住到现在,可能还要继续住下去。) We have been in the army for more than 5 years. 我们在部队已经呆了五年多了。 (动作开始于5年前,一直延续至今,有可能还要继续下去。) Have you waited long? 你等了很久吗?

现在完成时的基本用法

现在完成时讲解与练习 (一)现在完成时的基本用法 (1)强调动作是从过去持续到现在,并有可能继续持续下去。 (2)强调对现在的影响或结果,此用法容易和一般过去时混淆。两者的区别是:一般过去时有动作发生的时间点,即过去某一时间发生某一动作;现在完成时则没有,即不强调是哪个时间点发生的动作,而强调过去的动作对现在造成的影响和结果。 (3)在过去不确定的时间里发生的动作,但是结果对现在有影响。 一、现在完成时的构成 (一)肯定式 主语+助动词have /has +过去分词+其它 说明:这里的have /has是助动词,没有什么具体意义。当主语是第三人称单数时助动词用has,其余人称一律用have。 has,have的缩略式分别为's或've。规则动词过去分词的构成与过去式的构成方式一样,不规则动词可参看不规则动词表。实例: 1)I've just copied all the new words .我刚抄写了所有的生词。 (表示不要再抄了) 2)She has lost her books .她丢失了她的书。(表示到目前为止还没有找到)(如果用过去时:She lost her books . 则强调书是过去丢的这一动作,而不知现在有没有找到) 3)We've just cleaned the classroom .我们刚好打扫了教室。(表明现在教室是干净的) (二)否定式 主语+助动词have /has+not+过去分词+其它 说明:现在完成时构成否定句时,只需在助动词have /has后面加not就行。have not,has not的缩略式分别为haven't ,hasn't。另外,肯定句中有some,already 时,改为否定时要分别改成any,yet。实例: 1)I haven't finished my homework yet.我还没有完成我的作业。 2)She hasn't travelled on a train .她没有坐火车旅行过。 3)We have never spoken to a foreigner.我们从来没有和外国人说过话。 注:有时not可以用never代替,表示“从来没有”的意思。又如: 4)I have never seen him before.以前我从来没有见过他。 (三)一般疑问式

现在完成时的句型、用法及例句

现在完成时 一.构成 助动词have/has + 过去分词 例:肯定句I have worked. He has worked. 否定句I have not (haven't ) worked. He has not (hasn't )worked . 疑问句Have you worked ? Has he worked ? 回答Y es,I have. / No , I haven't . Y es, he has./ No, he hasn't. 二.功能及意义 1.表示一个动作发生在过去,对现在仍有影响,但没有具体的过去时间修饰。常由下列副词修饰:ever曾经,never从不,already已经,yet还(未),(yet 只用在否定句和疑问句中),just刚刚,recently,lately近来,so far 迄今为止= until now, up to now,before 以前 例:Have you ever been to the Great Wall? 你曾经去过长城吗? I have never heard of such a man.我从没有听说过那个人。 We have just had lunch 我们刚刚吃过午饭 I have already returned your money.我已经把钱还给你了。 I haven't found my book yet. (否)我还没有找到笔记本 Have you done your homework yet?(疑)你做作业了吗? Have you heard from him recently ? 你最近收到他的来信了吗? So far, no one has made any mistakes yet.迄今为止还没有人犯错误 I have never traveled by plane before .我以前从来没有乘飞机旅行过 2 表示一个动作发生在过去,一直持续到现在刚刚结束或者仍在继续。常常与下列时间状语连用: →for + 一段时间 I have learned English for 8 years →since + 过去的一个时间点 I have learned English since 2001 →since + 一段时间+ ago I have learned English since 8 years ago →since + 时态为一般过去时的时间状语从句 I have learned English since I was 5 years old → in the past/last +时间段 We have had two English exams in the past two months近两个月来我们进行了2次英语考试 Great changes have taken place in my hometown in the past ten years 近十年来我的家乡发生了巨大的变化。 三延续性动词与短暂性动词的用法
