第一篇：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

第三篇：现在完成时与一般过去时的区别
现在完成时与一般过去时的区别 一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系，一般过去时通常与表示过去的时间状语连用。如：yesterday, last week, two years ago, just now, in 2002等
现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday , lastweek , amomentago等）连用。
现在完成时的时间状语常有如下四类：
⑴现在完成时常与already（已经），just（刚刚，正好），ever（曾经），never（从来，也不；从不），before（以前），yet（仍然）等连用。
⑵现在完成时常与recently（近来），sofar（到目前为止），inthe past/“last + 一段时间”等时间状语连用。因为上述短语表示的是从现在起往前推算的一段时间，句中的动作是从过去某一时间或时刻开始持续到现在的。
⑶现在完成时时常与“for +时间段或since +过去时间点”连用（含从句，从句过去时）。
⑷现在完成时还与once（一次），twice（两次），threetimes（三次），severaltimes（几次）等表示重复次数的词语连用。
有时候是根据表时间的关键词来判断，如果没有的话，就看是着重于问一个过去的事实还是表示强调已经完成了对现在产生一定影响了这个事件。
你提出的问题：你还记得你上次去中国旅游是什么时候吗？（它本身就是问现在是否记得嘛，所以说一般用一般现在时，不存在用过去式和完成式）
did you remember sth.表示你过去某个
时候记得/记起某件事没有。have you remembered sth.表示你（已经）记住了某件事没有。
谓语动词的构成(1)一般过去时的谓语动词用过去式，而现在完成时的谓语基本构成是“助动词have /has +过去分词”。如：
看看以下的几组句子，有什么区别？
① Have you seen the film?(A)
Did you see the film?(B)
[说明] 你看过这部电影吗？(A)句强调的是被问者对剧情是否了解；(B)句强调的是看这部电影的动作是否发生过，并不强调是否知道其内容。
② How has he done it?(A)
How did he do it?(B)
[说明]他是怎么做的这件事？(A)句强调的是他做这件事的方式对现在产生了某种影响；(B)句单纯的询问做这件事的方式。
③ He has lived in Beijing for 8 years.(A)
He lived in Beijing for 8 years.(B)
[说明]他在北京住了8年。(A)句讲的是到目前为止他在北京住了8年，可能还会继续在北京住下去。(B)句讲的是他在北京住过8年，现在不在北京了。

一般过去时与现在完成时都是发生在过去的动作，但一般过去时就象used to do something 一样，是过去曾经做过某事，现在不这样了,与现在毫无延续性，补做性，影响性，是完全无关系了。一般过去时是已有历史定论的，与现在无关的，已尘封的历史往事，没有重做，补做的可能或必要。而现在完成时则强调过去动作对现在有影响，如未完成时极需及时重做，补做。如“Have you had breakfast？Where did you have it？When did you have it ？”强调你现在是饱还是饿的状态，如还没吃早餐那在时间上还完全来得马上去吃。询问的时间肯定是中午十一点之前问的，十二点时就没必要这样问了。因为不可能补吃早餐了，可以吃中餐了啊。至于用Where，When来提问过去动作，有了吃早餐的时间和地点，那吃早餐就立刻成为确定尘封的历史往事，肯定已经吃过早餐，无所谓重吃，补吃，无所谓饿的影响了。“你看过这部电影吗？”，问你现在知道这电影的内容吗，可以和我交流对这电影的看法吗？如你还没看过可找时间去补看。这些都是现在完成时的特点。下面判别一下那一句应该用现在完成时，那一句应用一般过去时？
1． 我明天去武汉，你去过武汉吗？I am going to Wuhan，have you been to Wuhan？
（对现在有影响）
2． 范仲淹去过武汉吗？（尘封的历史往事，用过去式）did Fan go to Wuhan ？
3． 你学过钢琴吗？能弹一首曲给我听吗？Have you learned playing piano ？Can you
play some music for me ？（对现在有影响）
4． 你小时候学过钢琴吗？你在北京的时候去过长城吗？（有确定时间，地点“小时
候”“在北京的时候”就肯定是尘封的确定的往事，纯过去时，不能用现在完成时。）
5． 老人家,你年轻时谈过恋爱吗?（有确定时间，地点“年轻时”“小时候”“在北
京的时候”就肯定是尘封的确定的往事，纯过去时，不能用现在完成时。）
6.你在偷笑,你一定是知道了什么我不知道的事情.You must have learned something that I haven‘tknown，for you are smilling in a strange way。（对现在有影响）
