第一篇：一般过去时,现在完成时,过去完成时的用法及区别
① 一般过去时的基本用法
a)表示过去某个特定时间发生的动作或存在的状态。常与过去时间连用.a moment ago(刚才)，yesterday morning，last night/ week，the day before yesterday(前天)，just now(刚才)等。
He suddenly fell ill yesterday.昨天他突然生病了。
b)表示过去经常发生的动作或存在的状态。
I wrote home once a week at college.我上大学时每周给家里写一封信.c)表示过去连续发生的一系列动作。
She entered the room, picked up a magazine and looked through it carefully.她走进房间，拿起一本杂志，认真地翻阅了起来。
d)在时间、条件状语从句中用一般过去时代替过去将来时.We would not leave until the teacher came back.老师回来我们才会离开。
②一般过去时的特殊用法
a)在虚拟语气中表示现在或将来时间的动作或状态。
I wish I were twenty years younger.但愿我年轻20岁。
b)在口语中，一般过去时往往显示委婉客气
Might I come and see you tonight?
我想今晚来看你，好吗？
现在完成时的用法:
1)表示过去发生或已完成的某个动作对现在产生的影响或结果，强调的是这个影响或结果，一般不与过去时间连用，常同already, just, yet等状语连用
例：I have just turned off the light.我刚刚把灯关上。（结果是灯已经关上了）She has lost her bike.她把自行车丢了。（影响是他现在没有自行车骑了）
2)表示开始于过去、持续到现在的动作或状态，并可能继续下去（也可能不继续下去），常同包括现在在内的时间状语连，也同“for+时间段”或“since＋时间点”的状语连用She has taught in the school for ten years.她在这所学校教书已经10年了。
I haven’t eaten anything since breakfast.我从早饭起就一直没有吃东西。
3)表示从过去某一时间到说话时这段时间中反复发生的动作或多次动作的总和，常同频度副词always, often, seldom, never等连用
I have been to the Great Wall twice.我曾经去过长城两次
过去完成时用法：
1.表示过去某一时间或动作之前已经发生或完成的动作或存在的状态。表示的是“过去的过去，常用的时间状语有：”by + 过去的时间点、by the end of + 过去的时间点、before + 过去的时间点。
Most of the guests had left when he arrived at the party.当他到达晚会时，他发现大多数客人已经离开了。
2.过去完成时还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间或持续下去，常与for，since等词连用。例如：
When Jack arrived, he learned Mary had been away for almost an hour.当杰克到时，他得知玛丽已经离开快一个小时了。
4.某些动词的过去完成时表示过去未实现的希望、计划或打算。常用的动词有hope，expect，suppose，think，want，wish等。例如：
They had hoped to be able to arrive before ten.他们本来打算能在10点之前到达达一、一般过去时与现在完成时的用法比较。
1.“一般过去时”所关心的是过去之事,与现在无联系，常带有表示过去某个时间的状语；现在完成时所关心的是过去发生的事，对现在产生某种结果，强调过去与现在的联系。一般不与过去具体时间连用。当需要指明过去一个特定的时刻发生的事情时，需要使用一般过去式。
Ａ.I ________(lose)my pen.Can you lend me yours?
Ｂ.Why don't you buy one?
Ａ.It _______(fall)into the river only a moment ago when I washed my hands.Now I've got to fill in a form with a pen.2.现在完成时与for或since引起的短语连用时，表达从过去开始的动作或状态延续至今，而一般过去时与“for＋一段时间”连用时，只指过去的动作或状态在过去延续了多长时间。
We___________(stay)here for three weeks.I think we are going to stay another two weeks.（说话时人还在）
He __________(stay)here for three weeks last year.（并不表示现在是否在）
3.一般过去时带有表示过去某时刻的时间状态，如yesterday,last year(month,week,night)，in 1980…
I ______(come)the day before yesterday.4.现在完成时所带时间状语包含说话时在内,如today,this week(month,year),these days(years)或与说话时非常接近，如recently,just,in(during)the past three years。Great changes _______(take)place in the last ten years
5如果一件事情发生在过去并且延续到说话的这个时刻，就需要使用现在完成时。They have lived here for a long time
6一般过去时比现在完成时更能表达事情的结果
John has taught math for twenty years.保留了约翰继续教数学的可能性
John taught math for twenty years.表明约翰已经不再教数学了，他可能退休了，换工作了，或者去世了。
7如果一件事情发生在过去并且延续到说话的这个时刻，就需要使用现在完成时。They have lived here for a long time.他们在这里已经生活了很长一段时间。
二、一般过去式与过去完成时的区别。
1.一般现在时表示过去某一时间内发生的动作或存在的状态，而过去完成时则表示过去某一动作或时间之前发生的动作或存在的状态。一般过去时与现在相比，强调“过去”，而过去完成时则与过去相比，强调“过去的过去”。
我们来比较下列句子：
The meeting _________(start)at six o'clock./ start的动作发生在at six o'clock。The meeting ___________(start)when we arrived at the hall./ start的动作发生在过去的动作arrived之前。
过去完成时与现在完成时的区别
现在完成时表示的动作发生在过去，以现在的时间为基点，但侧重对现在产生的结果或造成的影响，与现在有关。过去完成时则是一个相对的时态，以过去时间为基点，它所表示的动作不仅发生在过去，更强调“过去的过去”，只有和过去某时或某动作相比较时，才用到它。比较：I have learned 1000 English words so far.到目前为止我已经学会了 1000 个英语单词。I had learned 1000 English words till then.到那时为止我已经学会了 1000 个英语单词。
第二篇：一般过去时和现在完成时的区别
一般过去时和现在完成时的区别
时态是各种考试中经常考查的内容，学习者容易混淆的三组时态是：一般过去时和现在完成时、一般过去时和过去完成时、现在完成进行时和现在完成时。现在我们就谈谈一般过去时和现在完成时的区别。
一般过去时表示过去的动作或状态，这种动作或状态可能只发生过或存在过一次，也可能是经常性的。在含有一般过去时的句子中通常有表示过去的时间状语，常见的有：yesterday,last month,in 1999,two days ago等。同时也要注意过去时在语境中的运用，在没有明确时间状语的情况下，大家对过去时判定往往容易出错，原因是只凭汉语意思不看语境。语境中的过去时，往往表示“刚才，刚刚”之意，暗示“现在已不再这样”。例如： I didn’t know you were here.我不知道你在这里。
I never thought he would do that.我从没想到他会做出这样的事。
现在完成时所表示的动作虽然发生在过去，但与现在有联系。它既可表示到现在为止已完成的动作，又可表示没有完成的动作的动作，现在完成时有一些标志性的时间状语，如：already,yet,just,ever,so far,up to now,in the past five years等。现在完成时不能和表示过去特定的时间状语，如yesterday,last month,three years ago,in 1989等连用；但可以和表示不确定时间的状语，如：ever,never,just,not„just等连用，也可以和包括this
week,today等在内的时间状语连用。
一般过去时和现在完成时可以从以下几方面来区分。
首先，从一般过去时与现在完成时对现在情况的影响来区分。一般过去时所表示的过去一段时间是可以具体确定的，与其他时间没有联系。它所表示的事情纯属过去，与现在情况没有联系。现在完成时表示的事情发生在不能具体指出、现在以前的、过去某个或某段时间。它所表示的事情与现在情况有关系，是过去事情对现在产生的结果或影响。
其次，从与一般过去时和现在完成时搭配的时间状语来区分。一般过去时常用的状语有：yesterday,last night,two days(months,weeks)ago,at that time等；现在完成时常用的状语有：already,just,yet,never,before等；表示从过去延续到现在并包括现在在内的一段时间状语有：today,now,lately,recently,in the last/past few days/years,since then,up to now,so far（至今）等。
最后，请比较下面几组句子，以体会两种时态的不同。He served in the army from 1952 to 1954.He has served in the army for 5 years.I saw Hero last year.I have seen Hero before.综上所述，在区分一般过去时和现在完成时时，要重点区分时间状语和句中的谓语动词对现在的影响。
第三篇：一般过去时与现在完成时区别
一、现在完成时
1.现在完成时的构成：助动词 have(has)+动词的过去分词。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）表完成和结果：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?
在我不饿了）
（2）表持续：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.（可能还要继续教）
（3）表经验：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
短暂性动词不能与表示“一段时间”的状语连用。要用，必须改为延续性动词来表述。现归纳总结一下由
短暂性动词到延续性动词的转换：
arrive →be herebegin(start)→be ondie →be deadcome back →be back
leave →be awayfall ill(sick, asleep)→be ill(sick, asleep)get up →be up1-Yes, I have.I've just had it.（现
go out →be outfinish →be overput on →wear 或be onopen→be openjoin→be in或 be a member of„close →be closedgo to school →be a student
borrow →keepbuy→havecatch(a cold)→have(a cold)get to know →know
begin to study →studycome 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。
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）；have
gone(to)表示去某地了（说话时某人不在当地）。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）短暂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，since+一段时间+ago.如：I have lived here since my childhood.我从小就一直住在这里。
(5)在提问现在完成时的时间状语时通常用 how long。如：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，与现在没有关系。
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, 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。She has returned from Paris.她已从巴黎回来了。She returned yesterday.她是昨天回来了。
---Will somebody go and get Dr.White?---He's already been sent for.句中如有过去时的时间副词（如 yesterday, last week, in 1960）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.三、练习题

一般过去时与现在完成时区别专题
一、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。-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 herebegin(start)→be on
die→be deadcome back→be back
leave →be awayfall ill(sick,asleep)→be ill(sick,asleep)
get up→be upgo out→be out
finish →be overput on→wear 或be on
open→be openjoin→be in或 be a member of…
close→be closedgo to school→be a student
borrow→keepbuy→have
catch(a cold)→ have(a cold)get to know →know
begin to study→studycome 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.三、练习题

第五篇：现在完成时和一般过去时的区别
现在完成时和一般过去时的区别
1.现在完成时和一般过去时都表示在过去完成的动作, 但现在完成时强调这一动作与现在的关系, 如
对现在产生的结果、影响等，而一般过去时则表示动作发生在过去，一般不表示和现在的关系。试比较：① Who has opened the door?谁把门开了？（现在门还开着）
Who opened the door? 谁开的门？(指过去，与现在无关。现在门是关着还是开着，没有说明。)② — Have you had your lunch?你吃过午饭没有？（意即你现在不饿吗？）
— Yes, I have.吃了。（意即我现在饱了，不要再吃了。）
— When did you have it? 你什么时候吃的？（说话人感兴趣的是“吃”这一动作发生在什么时候。）
2.一般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, once, last week,...ago, in
1980, in October, just now等具体的时间状语。
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/last years, always等不确定的时间状语。
共同的时间状语：
this morning, tonight, this April, now, ever, before, already, recently, lately等。
3.现在完成时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等。
过去时常用的非延续性动词有come, go, leave, start, die, finish, become, get married等。eg.① 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。)
② 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。)
句子中如有一般过去时的时间状语（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.
