八年级动词时态专题.doc

期末考试前时态复习. 初中英语八种时态归纳复习 时态是英语学习中一个至关重要的内容，广大初中学生在实际运用时，往往对时态总是倍感棘手，下面我们就归纳复习一下这几种时态。 一、一般现在时： 概念：经常、反复发生的动作或行为及现在的某种状况。 时间状语： always, usually, often, sometimes, every week (day, year, month), once a week, on Sundays, etc.基本结构：be动词；行为动词 否定形式：am/is/are+not;此时态的谓语动词若为行为动词，则在其前加dont,如主语为第三人称单数，则用doesnt，同时还原行为动词。 一般疑问句：把be动词放于句首；用助动词do提问，如主语为第三人称单数，则用does，同时，还原行为动词。 二、一般过去时： 概念：过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为。 时间状语：ago, yesterday, the day before yesterday, last week(year, night, month), in 1989, just now, at the age of 5, one day, long long ago, once upon a time, etc. 基本结构：be动词；行为动词 否定形式：was/were+not;在行为动词前加didnt，同时还原行为动词。 一般疑问句：was或were放于句首；用助动词do的过去式did 提问，同时还原行为动词。 三、现在进行时： 概念：表示现阶段或说话时正在进行的动作及行为。 时间状语：now, at this time, these days, etc. 基本结构：am/is/are+doing 否定形式：am/is/are+not+doing. 一般疑问句：把be动词放于句首。四、过去进行时： 概念：表示过去某段时间或某一时刻正在发生或进行的行为或动作。 时间状语：at this time yesterday, at that time或以when引导的谓语动词是一般过去时的时间状语等。 基本结构：was/were+doing 否定形式：was/were + not + doing. 一般疑问句：把was或were放于句首。 五、现在完成时： 概念：过去发生或已经完成的动作对现在造成的影响或结果，或从过去已经开始，持续到现在的动作或状态。 时间状语：recently, lately, since,for,in the past few years, etc. 基本结构：have/has + done 否定形式：have/has + not +done. 一般疑问句：have或has。 六、过去完成时： 概念：以过去某个时间为标准，在此以前发生的动作或行为，或在过去某动作之前完成的行为，即“过去的过去”。 时间状语：before, bythe end of last year(term, month),etc. 基本结构：had + done. 否定形式：had + not + done. 一般疑问句：had 放于句首。 七、一般将来时：概念：表示将要发生的动作或存在的状态及打算、计划或准备做某事。 时间状语：tomorrow, next day(week, month, year),soon, in a few minutes, by,the day after tomorrow, etc. 基本结构：am/is/are/going to +do will/shall + do. 否定形式：am/is/are/ + not going to + do； wont / shant + do。 一般疑问句：be放于句首；will/shall提到句首。 八、过去将来时： 概念：立足于过去某一时刻，从过去看将来，常用于宾语从句中。 时间状语：the next day(morning, year),the following month(week),etc. 基本结构：was/were/going to + do；would/should + do. 否定形式：was/were/not + going to + do;would/should + not + do. 一般疑问句：was或were放于句首；would/should 提到句首。 . 几种常见时态的相互转换 英语中的几种时态在一定情况下可以互相转换，以下是几种常见的转换形式：一、一般过去时与现在完成时的转换 在现在完成时中，延续性动词能与表示一段时间的状语连用，瞬间动词却不能。但是，可以用别的表达方式：瞬间动词用于“一段时间 + ago”的一般过去时的句型中；瞬间动词可改成与之相对应的延续性动词及短语，与一段时间连用；瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中，表示“自从以来有时间”的意思，主句一般用it is来代替It has been;瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看： A. He joined the League two years ago. B.He has been in the League for two years. C. It is two years since he joined the League.D. Two years has passed since he joined the League.二、一般现在时与现在进行时的转换 在一般现在时中，at加上名词表示“处于某种状态”，如at work（在工作）, at school（上学、上课）等。此短语可与进行时态转换。请看： Peter is at work, but Mike is at play. Peter is working, but Mike is playing.三、现在进行时与一般将来时的转换 在现在进行时态中go, e, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作。如：I am ing, Mum! 意为“我就来，妈妈！”请看： The train is leaving soon. The train will leave soon. 四、“be going to+动词原形”与“will(shall)+动词原形”结构的转换 “be going to+动词原形”表示打算、计划要做的事；将来时“will(shall)+动词原形”结构在书面语中，当主语为第一人称时，常用助动词shall。在口语中，所有人称都可以用will。请看： We are going to visit the Great Wall next Sunday. We shall visit the Great Wall next Sunday. 初二英语上期末复习：动词时态专题本册书出现了几个主要的动词时态的用法，动词时态是英语学习中十分重要的内容。现将本册书出现的时态用法总结归纳如下：一、现在完成时（一）现在完成时的用法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，重点强调对现在造成的结果或影响。此种用法中的动词一般为终止性动词（也称非延续性动词），常与just, ever, never, yet, already, before等副词连用。例如：I have already seen the film. 我已经看过那部电影了。 （说明已知道内容，或不想再看了）She has just closed the door. 她刚把门关上。 （说明门现在是关着的）先将几个副词的用法说明如下：1) already的意思是“已经”。通常用于肯定句中，可放在助动词have/has之后，也可放在句末。在表示惊讶等的疑问句中也可用already。 例如：Have you seen the film already?你真的看过这部电影吗？2) yet用于疑问句的意思是“已经”，用在否定句的意思是“还”，常位于句末。just的意思是“刚刚”，表示动作刚刚完成，用于现在完成时，位于助动词have/has之后。 要注意与just now的区别：just now的意思是“刚才”，用于一般过去时。例如：The train has just left here.火车刚刚离开这儿。The train left here just now. 火车刚才离开这儿。3) ever 的意思是“曾经”，多用于疑问句中，一般位于过去分词之前。例如：Have you ever seen him?你曾经见过他吗？never 的意思是“从来没有”，常用在助动词之后。例如：I have never heard of him.我从来没有听说过他。before 的意思是“从前”，泛指过去不确定的某个时间，常位于句末。例如：I havent eaten Sichuan food before.我以前从未吃过四川菜。2. 表示过去已经开始，持续到现在的动作或状态，甚至还可能继续下去，常与for或since引导的时间状语连用。此用法中的动词必须是延续性动词，如live, study, work, be, wait, know, stay等。for为介词，后面要接“一段时间”。since用作介词时，后面接“时间点”； since用作连词时，后面接“从句”（从句谓语动词用一般过去时）。例如：I have known Jim for two years.我认识吉姆两年了。They have lived there since1995.从1995年以来他们就住在那儿。Uncle Wang has worked in the factory since he came here in 1998.王叔叔自从他1998年来这儿就在这个工厂工作。注：延续性动词与终止性动词的运用延续性动词可以和表示一段时间的状语连用。终止性动词所表示的是短暂的动作，如borrow, lend, buy, e, go, put, take, open, leave, give, die, finish, bee等，不能和表示一段时间的状语连用，一般要改为能够表示延续状态的词或短语。如：buyhave borrow/lendkeep diebe dead e/gobe leavebe awaybeginbe on joinbe + 名词/介词短语（join the Party = be a Party member/ be in the Party）试比较：他回来三天了。He has e back for three days. (wrong)He has been back for three days. (right)她奶奶去世五年了。Her grandma has died for five years. (wrong)Her grandma has been dead for five years. (right)3. 反复性用法，表示过去到现在这段时间内反复发生的动作。我本周就到过这座城市两次。I have been to the city twice this week.我一直在想她最近怎样拿到的钱。I have often wondered where she gets her money all these days.（二）现在完成时的构成现在完成时由“助动词have/has+动词的过去分词”构成 。除主语是第三人称用has外，其它人称的主语都用have。1. 肯定句结构：主语+助动词have/has+动词的过去分词+其它。例如：She has finished her homework.她已做完作业了。We have cleaned our classroom.我们已经打扫完教室了。2. 否定句结构：主语+助动词have/has + not + 动词的过去分词+其它。现在完成时的否定句，只需直接在助动词have /has 后面加上not构成。have not 与has not 可分别缩写为havent与hasnt。肯定句中有already时，一般要该为yet。 例如：They havent spoken to a foreigner.他们还没有与外国人说过话。 Miss Gao hasnt e back yet。高老师还没有回来。3. 一般疑问句结构：助动词Have/Has+主语+动词的过去分词+其它?现在完成时的一般疑问句直接把have/has提到主语之前构成，同时也要把句中的already该为yet。肯定的简略回答为： “Yes,主语+have/has”. 有时也可用“Yes, already”.否定的简略回答为“No,主语+havent/hasnt .”有时也可用 “No, not yet./ No, never./ Not yet. ”等。例如 1. Have you returned the book? 你把那本书还了吗？ Yes, I have. 是的，我还了。2. Have you found your lost bike yet? 你找到你丢失的自行车了吗？ No, not yet. 还没有。（三）一般过去时与现在完成时用法比较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. 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e,go,leave,start,die,finish,bee,getmarried等。3. 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,lastweek，ago,in1980,inOctober,justnow,具体的时间状语4. 现在完成时的时间状语： for,since,sofar,ever,never,just,yet, till/until,uptonow, inpastyears,always5. 现在完成时不能与表示过去的时间状语连用。一般过去时表示过去某个时间发生的动作或存在的状态，也可以表示过去习惯性的动作，不涉及与现在的关系，它常与表示过去的具体时间状语连用，如：yesterday, last year, in 1998, three days ago 等。现在完成时强调过去发生的某一动作对现在造成的影响或结果，以及过去已经开始并延续到现在的动作，与现在有着密切的关系，因而不能与表示过去的时间状语连用。6. 举例： Isawthisfilmyesterday. （强调看的动作发生过了。） I haveseenthisfilm. （强调对现在的影响，电影的内容已经知道了。） Whydidyougetupsoearly? （强调起床的动作已发生过了。） Whohasnthandedinhispaper? （强调有卷子，可能为不公平竞争。） ShehasreturnedfromParis.( 她已从巴黎回来了。) Shereturnedyesterday.（她是昨天回来了。） HehasbeenintheLeagueforthreeyears. （在团内的状态可延续） HehasbeenaLeaguememberforthreeyears. （是团员的状态可持续） HejoinedtheLeaguethreeyearsago. （三年前入团，joined为短暂行为。） Ihavefinishedmyhomeworknow.WillsomebodygoandgetDr.White? Hesalreadybeensentfor. 句子中如有过去时的时间副词（如yesterday,last,week,in1960）时，不能使用现在完成时，要用过去时。 （错）Tomhaswrittenalettertohisparentslastnight.（对）Tomwrotealettertohisparentslastnight.二、过去进行时（一） 概念和形式：过去进行时表示在过去某一时刻或某一段时间内进行或发生的动作。其形式为was /were + V-ing。常与表示过去的时间状语连用，如：last night, last Saturday等；或者与when, while, as引导的过去时间状语连用。例如：We were watching TV from seven to nine last night. 昨天晚上七点到九点的时候我们在看电视。What was he researching all day last Sunday? 上周日他一整天都在研究什么？（二）具体用法：1) 表示过去某一时刻或过去某段时间内正在进行的动作，一般要有表示过去时间的状语。例如：AtthattimeshewasworkinginOxford.那时，她正在牛津大学工作。Itwasrainingat6oclockthismorning.今天早晨六点钟天正下着雨。WhatwereyoudoingwhenIphonedyoulastnight?昨晚我给你打xx时你在干什么？2) 在含有时间状语从句的复合句中，延续性动词用过去进行时，非延续性动词用一般过去时。例如：TheywerewatchingTVwhenIenteredtheroom.我进入房间时，他们正在看电视。若主句和从句的动词均为延续性动词，则可以两边都可以采用过去进行时。例如：ThechildrenwereplayingwiththeirtoyswhileIwaseatingmydinner.我吃饭的时候，孩子们在玩他们的玩具。3) 可用来表示由过去某时持续到另一时间的过去动作。例如：HewasstudyinginCambridgebetween1999and2001.在1999年和2001年那段时间，他在剑桥学习。FromJanuarytoMarchIwastravelinginEgypt.从一月份到三月份期间，我在埃及旅游。这种时间状语亦可同一般过去时连用，如：例如：Heworkedfrommorningtillnightyesterday.昨天他从早到晚地工作。4) 表示故事发生的背景。Itwasasunnymorning.Somepeopleweresittingontheriverbank.Somewerewalkingwiththeirdogs.Severalboyswereplayingfootballnearby.一个阳光明媚的清晨。河堤上坐着几个人。有的人在溜狗。不远处有几个男童在踢足球.5）与某些动词连用时，代替过去将来时。这类动词有e来,go去,leave离开,start开始,stay逗留等。主语必须是人。例如：Hetelephonedme,sayingthathisauntwasingtoseemesoon.他打xx给我，说他姨妈很快就要看我了。注意：（一）有一些动词一般不用过去进行时：如agree, be, believe, belong, care, forget, hate, have(拥有), hear, know, like, love, mean, mind, notice, own, remember, seem, suppose, understand, want, wish等。例如：误：I was knowing the answer.正：I knew the answer. 我知道答案。误：I wasnt understanding him.正：I didnt understand him. 我不明白他的意思。（二）过去进行时与一般过去时的区别。A. 进行时表某一行为的“片断”一般时表示行为的“整体”和存在的状态。 I was reading the book at that time. (未读完，“读”的片段) I read the book yesterday. (已读完，表整个“读”) B. 一般持续时间状语多与进行时连用 It was raining all night. (优先用was raining ,rained 为持续动词，故也可使用) He was writing a letter the whole of afternoon. (短暂动词与持续时间连用，表反复，连续发生，不可用一般过去时) C. while 时间状语从句中用短暂动词时只能用进行时。 例如：He broke a chair while he was jumping up and down. D. While 所在主从句动作大致持续相等时主从句一般都用进行时，但若是持续动词可都用一般过去时， 两个动作一长一短时短的用一般时，长的用进行时。 I was cooking the dinner while he was playing the piano.(平行) I cooked the dinner while he played the piano. I saw him while I was walking to the station.三、巩固练习1. - Mum, may I go out and play basketball? - _you_ your homework yet? A. Do; finish B. Are; finishing C. Did; finish D.
