一般过去时与现在完成时的区别
1）一般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）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, last week，…ago, in1980, in October, just now等，皆为具体的时间状语。
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 years, always等，皆不确定的时间状语。
共同的时间状语：this morning, tonight, this April, now, already, recently, lately 等。
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.。
一般过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married 等。例如：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? （强调有卷子未交，疑为不公平竞争）
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）
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.
现在完成时是初中英语学习的重点和难点，初三同学学习现在完成时，应抓住关键。现总结以下四点，一定对同学们理解、运用现在完成时有所帮助，不妨一试。
一、现在完成时的意义（用法）
1.表示过去发生或已经完成的某一动作对现在造成的影响或结果。（瞬间动词适用于这种情况）
2.表示过去已经开始并持续到现在的动作或状态，可以和表示从过去某一时刻延续到现在（包括“现在”在内）的一段时间的状语连用。（延续性动词适用于这种情况）我们可以简记为：
（1）“过去对现在”（瞬间动词）
（2）“过去到现在”（延续性动词）
二、现在完成时的构成（结构）
现在完成时由“助动词have(has) + 过去分词”构成。
我们可以简记为：
①have(has)在前面，
②过去分词在后边，
③以前(before) 从来不(never) 出现，
④最近(recently) 曾经(ever) 一(once) 两遍(twice)，
⑤自从(since) 刚刚(just) for一段，今天(today) 已经(already/yet) 很明显。
注：1. ①②是指该时态的构成。③④⑤是时态的标志。
2. since +（1）（过去的）月份/年份
since +（2）一段时间+ago
since +（3）一般过去时从句
例如：
1. I have lived here for 9 years.
2. Wang Zhenrong has been teaching English here since 20 years ago.
3. Have you ever seen Mr Zhaos wife?
4. Weve never been there before.
5. Has Shi Qingyong had his lunch yet?
6. Wang Qishan has read the book twice.
三、关于瞬间动词的记忆口诀
现在完成在瞬间；非延只连时间点；终止需转换；否定方可碰一段。
注：1.瞬间动词又叫非延续性动词，还叫终止性动词。瞬间动词可以有现在完成时态，但不可以接一段时间，若要接一段时间，须要做一些相应的变换。
2.瞬间动词在完成时态中的否定式可以接一段时间。
初中阶段常见的瞬间动词有：
（1）来(come)、去(go)、到(get to/reach/arrive at)、离(leave)、看(see)、听（说）hear （2）买(buy)、卖(sell)、开(open)、关(close)、起床(get up)
（3）参加(join/take part in)、开发(begin/start)、还(return/give)（与）借(borrow/lend) （4）变成(become/turn)、带(bring/take)、给(give)、死(die)、完(finish/end)、接(receive/hear from)
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
注：has 用于第三人称单数，have 用于其他所有人称。
2．现在完成时的用法：
（1）现在完成时表示过去发生或已经完成的某一动作对现在造成的影响或结果。通常与表示包括现在在内的时间副词just，already, before, yet, never, ever等状语连用。例如：① I have never heard of that before.
② Have you ever ridden a horse?
③ She has already finished the work.
④ Have you milked the cow yet? Yes, I have done that already.
⑤I’ve just lost my science book.
有时没有时间状语；多是一般疑问句。
（2）现在完成时表示过去已经开始，持续到现在,也许还会持续下去的动作或状态。可以和表示从过去某一时刻延续到现在（包括现在在内）的一段时间的状语连用。如：for和since，以及 so far, now, today, this week(month, year) 等。
①I haven’t seen her these days.
② She has learnt English for 3 years.
③ They have lived here since 1990.
④ What has happ ened to the USA in the last 350 years?
注意：表示短暂时间动作的词，如come, go, die, marry, buy等的完成时不能与for, since 等表示一段时间的短语连用。
（3）现在完成时还可以用在时间和条件状语从句中,表示将来某时完成的动作，例如：
I’ll go to your home when I have finished my homework.
If it has stopped snowing in the morning, we’ll go to the park.
（4） have been (to)和have gone (to)的区别：
★have / has been (to) 表示“曾经去过”某地，说话时此人很可能不在那里，已经回来。侧重指经历。
★have / has gone (to) 表示某人“已经去了”某地，说话时此人在那里，或可能在路上，反正不在这里。
试比较：
He has been to Beijing. 他曾去过北京。
（人已回来，可能在这儿）
He has gone to Beijing. 他已经去了北京。
（人已走，不在这儿）。
A:
现在完成时棗表示到目前为止已经完成，并对现在留下某种后果和影响的动作。
结构：助动词have/has + 动词的过去分词
用法: 1.表示过去发生的某一动作对现在造成的影响或结果,常与一些时间状语,
如:already, yet, ever, never, just, before, once,twice等连用,也可以和包括现在
在内的时间状语,如these days,today,this year,so far等连用.
eg.I have already posted the letter. (信已经不在我这儿了)
2.表示过去发生的动作或存在的状态,一直持续到现在,也许还将继续下去,可以和表示从过去某一时刻延续到现在的一段时间的状语连用,即for +时间段,since+时间点/从
句, in the last ten years等,谓语只可用延续性动词.
解析： 1.英语动词根据词义可分为两种,一种是延续性的,一种是终止性的,终止性动词(也可称为非延续性动词,瞬间动词,或点动词),如begin,start,die,buy,leave, come等,表示
动作的发生与结束于一瞬间完成,不能再延续,所以它的现在完成时不能和表示延续的时间状语连用,即不能与表示一段时间的状语,for+时间段, since+时间点/从句连用,也不能用在how long引导的特殊疑问句中.
eg. I've left Shanghai for three days.(×)
I've been away from Shanghai for three days.( √ ).
I left Shanghai three days ago. ( √ )
It is /has been three days since I left Shanghai.( √ )
2.初中英语课本中常见终止性动词
有:leave, go, come, arrive, begin, buy, borrow, die, join, become等.终止性动词要表示持续时, 可用以下方法:
⑴.将时间状语改为时间段 + ago,句中谓语动词用一般过去时.
eg.我弟弟参军两年了. My brother joined the army two years ago.
⑵.若保留for+时间段,since+时间点/从句, 或用在 how long 句型中,则需将终止性动词改为相应的状态动词或延续性动词
常见终止性动词与延续性动词(或状态动词)的对应关系如下:
come/go/arrive/get/reach/move------be in/at open-----be open
die------be dead close----be closed become---be
borrow---keep begin/start-----be on put on----wear
leave-----be away (from) buy-----have fall asleep----be asleep
end/finish-----be over catch a cold-----have a cold
join the army----be in the army be a soldier
join the Party----be in the Party be a Party member
→My brother has been in the army for two years.
→My brother has been a soldier for two years.
3.现在完成时中been to,gone to和been in/at been to去过某地,表示某人的一种经历,可以和once,twice,already,ever,never等连用.
eg. She has been to Shanghai twice. (表示目前人在这里)
gone to 去某地了,说话时某人已离开此地,在去某地的途中或已在某地,
eg. She has gone to Shanghai。 (表示现在她人不在这里)
been in/at 逗留在某地(已经一段时间).常和for ten days,since I came here等连用.
eg. She has been in Shanghai since she moved there.
4.现在完成时和一般过去时的区别
现在完成时所表明的是过去发生的动作对现在的影响,强调的是现在的情况,不可以和表示过去的时间状语yesterday,in 1991,three days ago last time,last night等连用.
一般过去时表明的是过去发生的事实,和现在不发生关系.
5.现在完成时中的 for 与 since
for + 时间段与延续性动词的现在完成时连用
since + 时间点/从句
I have kept the library book for a week.= I have kept the library book since a week ago.
6. It is /has been +一段时间 + since 从句.自从某事发生已有一段时间了.
eg. It is /has been two years since my brother joined the army.
注意: 1.since 引导的从句中动词用过去时
2.when 引导的特殊问句不与现在完成时连用.
3.have got,has got 虽然是现在完成时,但have got=have has got==has

一般过去时 一、一般过去时的基本构成 1、be动词的一般现在时形式：was , were 2、其他动词用过去式的形式 二、一般过去时的基本用法 1、在确定的过去时间里所发生的动作或存在的状态。例如：时间状语有：yesterday, last week, an hour ago, the other day, in 1982等。 Eg ① He didn't finish his homework yesterday. ② We visited the factory last week. 2、表示在过去一段时间内，经常性或习惯性的动作。因此在这类句子中，经常 使用always，often，once a month等表示事情发生频度的时间状语。 ① When I was a child, I often played football in the street. ② Whenever the Browns went during their visit, they were given a warm welcome. 那时，布朗一家无论什么时候去，都受到热烈欢迎。 **表示过去经常性的、习惯性的动作也可以用used to do 来表示。（强调现在已经不这样了） Eg I used to get up early in the morning. 3、有些句子，虽然没有表示过去确定时间的状语，但实际上是指过去发生的动 作或存在的状态的话，也要用过去时。 Eg I didn’t know you were in Paris. 我不知道你在巴黎。 （因为在说话时，我已经知道你在巴黎了。这句话指的是说话之前，所以只能用过去时表示。实际上，这句话暗指：But now I know you are here.） I thought you were ill. 我以为你病了呢。 （这句话应是在说话之前，我以为你病了。但是现在我知道你没病） 4、wish, wonder, think, hope等用过去时，作试探性的询问、请求、建议等，而一般过去时表示的动作或状态都已成为过去，现已不复存在。 Eg I thought you might have some. 我以为你想要一些。 Christine was an invalid all her life.（含义：她已不在人间。） Christine has been an invalid all her life.（含义：她现在还活着） Mrs. Darby lived in Kentucky for seven years. （含义：达比太太已不再住在肯塔基州） Mrs. Darby has lived in Kentucky for seven years. （含义：现在还住在肯塔基州，有可能指刚离去） 5、用过去时表示现在，表示委婉语气。 ①动词want, hope, wonder, think, intend等。 Eg Did you want anything else? 您还要些什么吗？ I wondered if you could help me. 能不能帮我一下。 ②情态动词could, would。 Eg Could you lend me your bike? 你的自行车，能借用一些吗？ 6、特殊句型： ①It is time for sb. to do sth “到……时间了”；“该……了”。 Eg It is time for you to go to bed. 你该睡觉了。
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。
一般过去时，现在完成时和过去完成时 一般过去时态表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用，也表示过去经常或反复发生的动作，常和表示频度的时间状语连用，试看下列例句： 1. I was in the classroom yesterday morning 2. My father was at work last week. 3. I visited the Palace Museum three weeks ago. 4. He always went to work by bus last year. 5. I wrote home once a week at college. 1. yesterday或以其构成的短语：yesterday morning(afternoon, evening)等； 2. 由"last+一时间名词"构成的短语：last night, last year (winter, month, week)等； 3. 由"时间段+ago"构成的短语：a moment ago, a short time ago, an hour ago等； 4. 其它：just now或者由句子本身的时态所反映出来的。 现在完成时表示：(1)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，just，yet，before，ever，never 等副词连用；(2)发生在过去某一时刻的,持续到现在的动作（用行为动词表示）或状态（be动词表示），常与for（+时间段），since（+时间点或过去时的句子）连用。试看下列例句： 1.My father has brought many books for me , so I can do some reading now. 2.I have already finished my homework, so I can give it to my teacher now. 3.Kevin hasn't seen the film yet, so he has nothing to say about the film. 4.This is the best film I have ever seen. 5.Mary has been ill for three days. 6.I have lived here since 1998. 现在完成时不能和表示过去的时间状语连用，如yesterday, last year, two days ago, just now 等等，但可以和already, yet, sometimes, always, before, recently,ever, never等连用。
现在完成时和过去时的区别及练习 一、现在完成时的用法。 1.现在完成时强调过去动作对现在的影响 I have lost my wallet now. I can’t find it now. 我的钱包掉了，我现在找不到。 2.现在完成时强调过去动作一直持续到现在。 I have had this book for a year. 我拥有这本书1年了。 3.现在完成时表示动作尚未完成。 I have lived here for 5 years. 我在这里住了5年（现在也还在这里住） 4.现在完成时可以与不确切的过去时间连用。 She has entered speaking competition before. 她曾经参加过演讲比赛。 5.现在完成时可以用来描述活着的人的经历。 He has been to America four times. 他去过美国4次。（他现在还活着） 6.现在完成时可以与未完成的时间状语连用。 She has finished her homework today. 今天他已经完成了家庭作业。（today, this week, this year 是未完成的时间状语） 二、过去时的用法 1.
1.表示过去完成的动作，现在已不是这样。 —What do you think of her? 你认为她怎样？ —She was cute. 她曾经很可爱（表示她现在已不可爱了。） 2.与过去某一具体的时间状语连用，表示过去完成的动作。 She lost her wallet yesterday. (她昨天弄丢了她的钱包。) 3.表示去世的人过去的经历。 He went to America four times.一生中, 他去过美国4次（表示他已去世）练习 1.Ronaldo ______________( win) 29 major trophies in his career. 2.I ____________(have)him for three months and I really feel healthy. 3.She_______________(be) ill for three days. 4.They ________________ (not do) much exercise since they got their computer. 5.Kobe Byrant _______________(win) five championships with The Los Angeles Lakers. 6.Fans___________________(buy)about 200 million copies of Tintin’s stories in more than 50 languages. 7.When I was young, I ___________(not like) green vegetables. 8.After he graduated from university, he _________(work) in a big company.

现在完成时态与过去时态的区别 1. 意义上的区别 一般过去时态只是单纯地表示过去某一时间发生过的动作或者存在的状态, 和现在没有任何联系, 只着眼于过去. 现在完成时态重点强调与现在的联系, 表示过去发生的动作对现在造成的影响和结果, 属于现在时的范畴. 试比较下列例句: I have washed my shoes . 我刷过鞋了. 强调的是过去的某一时间发生的动作"洗" 对现在产生的影响是" 鞋是干净的" . I washed my shoes yesterday . 我昨天刷了鞋. 强调昨天做过"洗" 这个动作, 与现在鞋是否干净没有关系. My father has bought a new car . 我爸爸买了一辆新车. 强调在过去的某一时间发生的动作"买" , 对现在造成的结果是" 他有了一辆新车". My father bought a new car last Sunday . 我爸爸上个周日买了一辆新车. 强调上个周日"买" 这个动作发生过, 与爸爸现在是否有车无关. 也许这辆车是给别人的. 2. 时间状语的区别 一般过去时态只能与表示过去的时间状语连用, 如 yesterday, la st week, three years ago, in 1990 , just now 等.
现在完成时态中的时间状语表达的时间是到现在为止. 如: just 刚刚, before 以前, "since / ever since +过去时间 " 自从...... 开始, ev er 曾经, never 从未, 未曾, "already" 已经 , " for+ 时间段"已有多长时间了. in the last/ past ten years 在过去的十年里, so far 到目前为止. up to now 直到现在, this week 这个星期等等. 二者的根本区别在于过去时强调事实，常有具体的时间状语标志，如，yesterday/5.oclock/this morning,just now,ago etc---, examples: 1.I met her a week ago. 2.We have a English class this morning. 而完成时有两种用法或意义 1，影响性：也是一个过去动作但却强调它对现在的影响,没具体时间点作时间状语，但常有，already,yet,before,just作状语。 (1).Have you had your breakfast,yet?(2).I have seen this movie before. (3).He has just finished his homework. 2.持续性：表动作从过去的一个点开始，一直持续到现在。（现在完成时）如果只需到过去的另一个点就是过去完成时。动词要用延续性的，还常有 for（引导线状时间状语），since（引导点状时间状语） (1).I have been worked here for 20 years./I have worked here since 20 years ago. (2).I have been a member of the League for 2 years.这里的be a member of 代替不可延续的动词短语join the League。
I have cleaned the classroom .（强调扫地所产生的结果：地干净了！） We have lived here for ten years.（“住”从过去持续到现在的动作用现在完成时） We have lived here since we came here.（“住”是从过去持续到现在的动作用现在完成时） Mr Green had lived in New York for ten years before he came to China.("来”中国已过去，而先前“住”在纽约更过去！）（另外注意：“住”在纽约可没有持续到现在！） We had learned 1000 words by the end of last term. （“上期期末”已过去，而是在其前“学”的就更过去了！） 一、从结构上区别 现在完成时： 主语 + have / has（not） + 过去分词 过去完成时： 主语 + had (not) + 过去分词 (二)从时间状语区别 现在完成时: 常用的时间状语包括“now, today, tonight, this week, this year, already, yet, just, recently…etc”。 过去完成时: 常用的时间状语包括“by, at, before等构成的短语”。 注意：当表示一段时间，现在完成时和过去完成时都可以用for 或since引导的状语。 例如： The meeting had begun when we got there. 我们到那儿时，会议已经开始了。 We had learned about 500English words when we were 6 years old. 我们六岁时就已经学了500个英语单词。
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。
一般过去时和现在完成时用法区别（详细点） 1) 经常性或习惯性的动作，常与表示频腮度的时间状语连用。时间状语：every…, sometimes, at…, on Sunday I leave home for school at 7 every morning. 2) 客观真理，客观存在，科学事实。 The earth moves around the sun. 不受时间限制的 Shanghai lies in the east of China. 客观存在 表示格言或警句中。 Pride goes before a fall. 骄者必败。 注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。 例：Columbus proved that the earth is round.. 3) 现在时刻的状态、能力、性格、个性、特征。 I don't want so much. Ann Wang writes good English but does not speak well. 比较：Now I put the sugar in the cup. I am doing my homework now. ※4)由连词if unless before as soon as when once however 等引起的时间(条件、让步)状语从句,需要用一般现在时,表示将来时. 第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。 现在完成时用法解析 1.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.用法 （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
过去进行时的用法归纳 过去进行时是英语语法中常用的一种，大家都知道过去进行时要怎么用吗? 特地整理归纳了过去进行时的使用方法，来看看吧。 一、过去进行时的时间状语 1. when 和while引导的状语从句中，强调某个动作正在进行的过程中时要用进行时态，while表示一段时间，因此它所引导的状语从句中，谓语动词常用进行时态，如： When/While we were having supper, the light went out. 我们正在吃饭时灯熄灭了。 2. when用作并列连词时，主句常用进行时态，从句则用一般过去时，表示主句动作发生的过程中，另一个意想不到的动作发生了。如： I was walking in the street when someone called me. 我正在街上走时突然有人喊我。 @ 二、下面几种情况不用一般过去时而要用过去进行时 1. 表示过去某一阶段暂时性的习惯动作时。如： Tom was getting up at six o’clock every day that week. 汤姆那一周里每天都是六点钟起床。 2. 与always连用表示赞美，厌烦等感情色彩时。如： John was always coming to school late. 约翰上学总是迟到。
Lei Feng was always doing good deeds for the people. 雷锋总是为人民做好事。 3. 用来描写故事发生的情景时。如： : It was a dark night. The wind was blowing hard and the rain was falling heavily. A PLA man suddenly appeared on the river bank. He wanted to cross the river.那是一个漆黑的夜晚，风刮得很厉害，雨下得很大，一个解放军战士突然出现在河岸上，他想过河去。 4. when作并列连词，表示“(这时)突然”之意时，第一个并列分句用过去进行时，when引导的并列分句用一般过去时。如： I was taking a walk when I met him. 我正在散步，突然遇见了他。 We were playing outside when it began to rain. 我们正在外边玩，这时下起雨来了。 5. go, come, leave, start, arrive等动词可用过去进行时表示过去将来的含义。如： I was leaving for Wuhan that day. 那天我正要去武汉。 She was coming later. 她随后就来。 . 三、过去进行时表示婉转语气 (只限于want, hope, wonder 等动词)，用以提出请求。如： I was wondering if you could help me.
