瞬间动词转换成持续性动词 瞬间动词用于完成时态不能与一段时间状语连用，须转换成持续性动词。 1.用相应的延续性动词替换的有： buy---have borrow---keep put on----wear catch/get a cold---have a cold come/go/become---be 等。 eg. 1.We have had the TV set for 3years. 2.I have kept the book for 2 weeks. 2.转换成be+名词的有： join the army----be a soldier join the Party----be a Party member go to school----be a student 等。 eg. 1.He has been a soldier for 5 years. 2She has been a student for 2 months. 3.转换成be+adj/adv. die—be dead finish—be over begin---be on leave---be away move----be out of
put on---be on open---be open close---be closed fall asleep------be asleep 等。 eg. He has been dead for 5 years. 4. 转换成be+介词短语 go to school----be in school join the army---be in the army 等。 eg. 1.She has been in the army for 2 years. 2.He has been in school for 9 years. 5.通过去掉短语中的结束性动词 get to know---know begin to study---study come to work----work eg. 1.We have known each other for 10 years. 2.He has study Chinese for 2 years. *瞬间动词完成时的否定式已成为一种可延性状态，因此可以和表示一段的时间状语连用。 eg. 1.I haven’t heard from her for 6 months. 2.I haven’t bought anything for 2 months.
延续性动词与非延续性动词及其转换 动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词。 一.延续性动词表示能够延续的动作,如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。延续性动词可以与表示时间段的状语连用。 表示时间段的短语有:for+一段时间,for 2 years; since从句,since he came here; since+时间点名词,since last year, since 5 days ago; how long; for a long time等。 例:He has lived here for 6 years. You can keep the book for 5 days. I stayed there for 2 weeks last year. How long did you stay there last year? 二.非延续性动词也称终止性动词、瞬间动词,表示不能延续的动作,这种动作发生后立即结束。如:open, die, close, begin, finish, come, go, move, borrow, lend, buy等。 非延续性动词在肯定句中与表示时间点的状语连用，如：two years ago; at 5 o'clock; 例:He died 5 years ago. 否定的终止性动词可以与表示时间段的时间状语连用。例:I haven't left here for 3 years. I haven't heard from him for 3 weeks. 三.延续性动词与非延续性动词之间的转换：leave --- be away, borrow --- keep, buy --- have, begin/start --- be on, die --- be dead, finish --- be over, join --- be in+组织机构, be a member of+组织机构, open sth --- keep sth open, fall ill --- be ill, get up---be up, catch a cold --- have a cold, come here --- be here, go there --- be there, become --- be, come back --- be back, fall asleep --- be asleep, get to/ arrive/reach --- be (in), leave --- be away from, get to know --- know, go (get) out →be out，put on→wear；catch a cold →have a cold 等。例:The old man died 4 years ago. ----The old man has been dead for 4 years. ---- It is 4 years since the old man died. ----Four years has passed since the old man died. He joined the Party 2 years ago. -----He has been in the
现在完成时之瞬间动词转变为持续性动词 （1）专题讲解： 在完成时中,一个瞬间性动词(一次性动作)不能与表示一段时间的状语(for, since, how long等)连用,此时须将该瞬间动词改为延续性动词或状态动词. Eg: buy ( bought ) --- have / has had 买 borrow (borrowed) --- have / has kept 借 die ( died ) --- have / has been dead 死 leave ( left ) --- have / has been away ( from ) 离开 begin ( began ) --- have / has been on 开始 join ( joined) --- have / has been in 参加 --- have / has been a ( party) member go (went) --- have / has been there / in 去 come/arrive/reach/get to --- have / has been here / in 来/到达 end (ended) ----- have/has been over 结束 eg. The film began five minutes ago. ------The film has been on for five minutes. ------It has been five minutes since the film began. 用“be＋形容词”代终止性动词 1、be＋married代marry 2、be＋ill代fall (get) ill 3、be＋dead代die 4、be＋asleep代fall (get) asleep 5、be＋awake代wake/wake up 6、be＋open代open 7、be closed代close/shut 用“be＋副词”代终止性动词 1“be＋on”代start,begin 2“be＋up”代get up 3“be＋back(to)”代return to,come back to,go back to 4“be here (there)”代come(arrive,reach,get) here或go (arrive,reach,get) there等等 用“be＋介词短语”代终止性动词 1.“be in/at +地点”代替go to /come to 2.用be in the army 代替join the army 3.“be in/at +地点”代替move to
延续性动词与非延续性动词 动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词。 一．延续性动词表示能够延续的动作,如:stuｄy, ｌearn，work, ｓｔanｄ,ｌie,ｋｎｏw, ｗalk, keep, ｈave,waiｔ, ｗａtch, sing，ｒeaｄ, sleep，li ｖe,ｓtaｙ等。延续性动词可以与表示时间段的状语连用。延续性动词的用法很广，常见于现在完成时中的句子中,且常与for，ｈoｗ，lｏng，since等引导的表示一段时间的状语或状语从句连用。 表示时间段的短语有: 1.foｒ+一段时间, eｇ: fｏｒ2 yeａｒs; fｏr a lonｇｔiｍｅ等 ２.since从句，siｎｃｅhe came ｈeｒe; ３.sincｅ＋时间点名词+agｏ, eｇ：since ｌast yeaｒ, ｓinｃe 5dａyｓago; 4.ｈoｗloｎg; 二.非延续性动词也称终止性动词、瞬间动词或点动词,表示不能延续的动作,这种动作发生后立即结束。如：oｐeｎ,diｅ,clｏsｅ, beｇin，ｆinish,ｃoｍe, go, ｍove, boｒroｗ, lend, ｂｕy, move, happen,mａrry,ａrrive/rｅa ｃｈ, ｐost，fａlｌ, breaｋ, ｌｏsｅ,ｇｉve, jｏin, rｅｃeｉve,hear，he
间的的状语连用。 这类动词不是不能用于完成时态。只是不能用于由ｈow loｎg提问的句子和含有ｆoｒ＋一段时间的完成时态中。 常见的这类动词有：ｇo, cｏme，leave,aｒrive,lｏsｅ, lａnd, ｃatch，j ｏin, kilｌ，fiｎd等。 例如：1. Hｅhａｓjoinｅd tｈe ｃluｂforａlong time．( 错) 2.Hｅｈaｓbeenａmｅmbeｒof thｅclub ｆoｒa ｌong tiｍｅ.(对) 3．His gｒａｎdｆａther ｈａs died for ovｅr30 yeａrｓ. ( 错) 4. Hｉsｇｒａnｄfather hａs been dead for over 30 ｙearｓ. (对) 【注意】 之所以将这些动词称为瞬间动词,是因为这些动词在眨眼之间发生并终结。故不能与表达“段”的长时间状语连用，不论是在进行时还是现在完成时中。 下面的例句是正确的： 1. He iｓdｙinｇ.
一．延续性动词和非延续性动词： ㈠延续性动词：表示一种可以持续的行为过程或状态。 drink喝have有talk说know 知道stand站立sleep睡觉sing唱歌wait等wear穿walk走work工作rain下雨keep保持snow 下雪eat 吃read读play玩live 居住smoke 抽烟lie躺着stay保持㈡终止性动词：（非延续性动词），表示行为或者动作是短暂瞬间完成的。come来fall倒borrow借admit承认break打破start开始join加入buy买jump跳lose丢open打开close关stop结束begin开始go走put放die死hit击中leave离开arrive到达marry结婚㈢两者的用法和区别： 1.延续性动词可以用表示一段时间的状语修饰，非延续动词不可用。 How long can I keep the book. 这本书我可以借多久？ They will work here till next Friday. 她们要在这里工作到下周五。 2.有时，非延续性动词也可以与表示一段时间的时间状语搭配，但这种表示一段时间的状语,实质上是表示一段时间内的某个时间“点”。 The play will start in half an hour. 这出戏半个小时后开始。 The fire broke out during the night. 火是夜间发生的。 3.非延续性动词一般不用于while引导的时间状语从句中。 While I came home, he was cooking dinner. (错) When I came home, he was cooking dinner. (对) 4.用延续性动词表示一时的动作，可以在该动词前加get/begin/come. When did you get to know him? 你什么时候认识他的？ They begin to see that they had made a serious mistake. 她们开始认识到自己犯了一个大错。 5.非延续性动词的否定式表示动作的否定，此时可与表示一段时间的状语搭配。We did not find our seats till the play had begin. 我们直到戏开始时才找到位子。 We have not come here for ages. 我们多年没来这里了、 The rain has not stopped since three hours ago. 这雨已经下了三个小时了。 二：一般过去时和过去进行时的区分： ㈠一般过去时： ①概念：过去某个时间里发生的动作或者状态；过去经常，反复发生的动作。 ②时间状语：一段时间+ago, yesterday, the day before yesterday, last week, last(year, night, month…), in 1989, just now, at the age of 5, one day, once upon a time, the other day(前几天），at that time(当时)，etc. ③基本结构：主语+动词过去式+其他

现在完成式中瞬间性动词如何变为延续性动词。 在完成式中，一个瞬间性动词（一次性动作如buy, borrow,die,leave,begin,join等）不能与 表示一段时间的状语（for, since, how long等）连用，此时须将该瞬间动词改为延续性动词或状态动词. 女口：He borrowed a book two days ago.（用现在完成式表达） He has kept the book for two days. 他持有这本书两年了。 1、 _______________________________________________________________ 他三年前买了一辆车。 2、 _______________________________________________________________ 他两年前参了军。 答案：1、He has had a car for three years或He has bought a car.或He bought a car three years ago. 2、He has been in the army for two years或He has joined the army. He joined the army two years ago. 切记：有些动词是非延续的，在此用法中要换成其相对应的延续性动词： His father has died. His father has been dead for three years. 他父亲已经去世三年了。 She has joined the Party/League. She has been in the Party/ League for two months.=She has been a Party/ League member for two mon ths.
when和while引导的时间状语从句与这一时态连用。所以区别when和while的用法成了这一单元的难点。（一）、when，while都有“当……时候”的意思。when既可表示某一点时间，也可以表示某一段时间。在when引导的时间状语从句中，其谓语动词可以是延续性的，也可以是非延续性的，可与主句中的谓语动词同时发生，也可在其后发生。例如： 1、I was just reading a book when she came into my room. 她走进我房间时，我正在看书。 2、Were you writing when the teacher came in? 老师进来的时候，你在写信吗？ 3、When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。（二）、while只能表示某一段时间，不能表示某一点时间。在while引导的时间状语从句中，其谓语动词只能是延续性的，而且也只能与主句中的谓语动词同时发生或存在。例如：1、While Jim was mending his bike, Lin Tao came to see him. 正当吉姆修自行车时，林涛来看他。 2、You can’t do your homework while you’re watching TV. 你不能一边看电视一边做家庭作业。（三）、另外，when和while的区别还在于：while引导的时间状语从句多用进行时态，而when引导的时间状语从句多用一般时态。例如： 1、While they were talking , the bell rang. 正在他们谈话的时候，上课铃响了。 2、I was doing my homework when my mother came back home yesterday evening. 昨天晚上妈妈回家的时候 一、延续性动词和终止性动词的概念 英语中，动词按其动作发生的方式、动作发生过程的长短，可分为延续性动词和终止性动词。 延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay 等。 终止性动词也称非延续性动词、瞬间动词或短暂性动词，表示不能延续的动作，这种动作发生后立即结束。如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。 二、延续性动词的用法特征 1.延续性动词可以用于现在完成时，其完成时态可与表示"段时间"的状语连用。表示"段时间"的短语有：for two years, during the past three years, since last year, how long 等。如：I have learned English since I came here.自从我来到这儿就学英语了。 2.延续性动词不能与表示短暂时间的"点时间"状语连用。如：It raind at eight yesterday morning.(误) rain为延续性动词，而at eight表示"点时间"，前后显然矛盾。如果用延续性动词表示一瞬间的动作，可以借助come, begin, get等终止性动词来表示。上句可改为：It began to rain at eight yesterday morning.(正)又如： -When did you get to know Jack? -Two years ago.
终止性动词与延续性动词之间的转换 终止性动词(也可称为非延续性动词,瞬间动词,点动词或短暂性动词),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. 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 The film started two hours ago．→The film has been on for two hours． 常见短暂性动词与延续性动词的转换 Ⅰ. be 型 1. go there -- be there https://www.doczj.com/doc/1a18204822.html,e here—be here https://www.doczj.com/doc/1a18204822.html,e back—be back 4.die—be dead 5.leave—be away(from) 6.open—be open 7.close—be closed 8.go/get out—be out 9.finish/end-- be over 10.become—be 11.get up—be up 12.begin/start(上演)—be on 13. fall asleep-- be asleep 14.fall ill – be ill 15. move here/there --be here/there 16. get to… --be at/in 17.arrive at / in… -- be at / in 18.reach…-- be at/in 19.get married --be married 20.join—be in/be a member of join the Party-- be in the Party / be a Party member/ be a member of the Party Ⅱ. 实义动词型 1.borrow-- keep 2. buy——have 3.Begin to teach—teach 4. get to know—know 5.Put on—wear 6. receive--have 7.catch a cold—have a cold 8.hear from—have a letter from ［注意点］ 1．上述例词除borrow／buy／catch需转换为keep ／have外，其余均为“be＋adj．／adv．／n．”结构。2．非延续性动词并非不可用于现在完成时态中，只是不能和表示“一段”时间的短语连用，但可与just，yet，already ，ever，never等连用。例如： They have already come． He has just gone out．
瞬间动词与延续性动词 “瞬间动词”又叫终止性动词、点动词，表示动作有一个终点，到了终点就不能再延续。因此在现在完成时的句子中，瞬间动词不能直接与for/since 连用，需要转换成“延续性动词”。常用的请见5BP17表格。 Exercises 一、改错：横线划出错误的部分，并在后面的横线上改正。 1. How long have you begun to study English? ________________________ 2. I have borrowed this book for two weeks. ________________________ 3. The river has become very dirty since last August.___________________ 4. Our manager is away today. He has been to Guangzhou on business. ___________________________ 5. He has gone out for two years. ________________________ 二、选择 （）1. Her grandfather ______ for two years. A. died B. has died C. has been dead D. has been died （）2.

延续性动词与非延续性动词 试比较，判断下列句子的正误。 翻译：我离开这所学校已八年啦。 【误】I have left this school for eight years. 【正】I have been away from this school for eight years. 解析：当现在完成时与表示一段时间的时间状语连用时，谓语动词必须使用延续性动词。如果谓语动词是非延续性动词则需要转化为对应的延续性动词。 延续性动词表示能够延续的动作，也可 以表示经验与经历，如： learn; sleep; keep; live等 可以与for 和 since 引导的 时间状语连用 He has lived here for 6 years. 非延续性动词也叫短暂性动词，表示不能 延续的动作，这种动作发生 后立即结束，如：open; begin; finish; come; go; borrow等 不能与for 和 since 引导的 时间状语连用 She has already finished her work. 1. 转化为相应的延续性动词 borrow → keep buy → have put on → wear 2. 转化为be+形容词/副词/介词/名词 begin/start → be on go out → be out die → be dead open → be open get to/ arrive in/reach → be in+地点come/ go → be + 相应的介词短语 finish → be over fall ill → be ill get up → be up fall asleep → be asleep join → be in+活动/组织go to school → be in school become → be make friends → be friends close → be closed go to bed → be in bed leave → be away(from)
英语中瞬间动词和延续性动词 一、瞬间动词和延续性动词的含义及用法： 1.瞬间动词是指动作短暂、不长久的动词，如begin, become, sell, buy, borrow等。其用法有： ①常与点时间连用。例如：She often goes to bed at ten.她经常十点钟睡觉。 ②不能与段时间连用。例如：He has joined the army for two years. (×)She has come here for half an hour. (×) 2.延续性动词是指长久的、可以延续的动词，如sleep, know, keep, wait, study等。其用法为： ①常与段时间连用。例如：Mr Zhang has lived here for two years.张先生在这儿住了两年了。 He has taught there since 1987.自1987年来他一直在那儿教书。 ②不与点时间连用(do, have, eat等除外)。例如：Mary has worked at eight. (×)She walked at five yesterday. (×) 二、非延续性动词可以转换成延续性动词，主要有以下几种： ①、用相应的延续性动词； buy ------ have, borrow ----- keep, put on ------ wear, catch/get a cold ------ have a cold, come/go/become ------ be. ②、转换成be＋名词; join the Party ------ be a Party member, join the army ------ be a soldier, go to school ------ be a student. ③、转换成be + 介词短语: go to school ------ be in school, join the army ------ be in the army. ④、转换成be + adj./adv. : die ------ be dead, finish ------ be over, begin/start ------ be on, leave (…) ------ be away (from), close ------ be closed, open ------ be open, fall asleep ------ be asleep. 常见的瞬间动词变为延续性动词： 1、go——be away 2、come/arrive——be here
延续性动词和短暂性动词转换归纳 瞬间动词可以用于现在完成时，但不能和表示一段时间的状语连用如:for 和since 所引导的时间状语都表示一段时间.那就要将瞬间动词转化为表延续的动词或者表状态的be+名词／形容词或副词／介词短语等。 leave—been away from buy—have borrow—keep die—be dead get up—be up put on—be on / wear come / get back—be back go to town—be in town lose—be missing catch a cold—have a cold close—be closed / not open open —be open fall ill / asleep— be ill / asleep begin /start—be on return--be back marry---be married finish--be over become--be come / go to —be in / at arrive in （at）/ get to / reach——be in / at join + 名词-------be in + 组织/ be a（an）+组织成员get /receive a letter from—have a letter from
一看时间状语。如果句中没有表示过去确切时间的状语，常用现在完成时；如果有，则只能用一般过去时。如： I have visited the factory. I visited the factory last year. 二看句首有无疑问词。如果笼统地问人家做过某事了吗（句首无疑问词），常用现在完成时；但进一步询问何时、何地、何原因、用什么方式做那事时（句首有疑问词）就要用一般过去时。如：－Have you had your breakfast? －Yes, I have. －When did you have it? －At seven thirty. 注意：这种用法是以连贯性问答为背景的。否则就需要具体情况具体分析。如： How many words have you learned by heart? How did you learn them by heart? 三看句中谓语动词是否为延续性动词。如果表示的动作或状态一直延续到现在，最好选用延续性动词，并使用现在完成时；如果是瞬间动词，则用一般过去时。如： He has been a league member for two months. He joined the Youth League two months ago.
最佳答案 since+时间点 for+时间段 eg:He has kept the book for two weeks. He borrowed the book since two weeks ago. 注意动词的时态，for后面是一段时间，动词用完成式，而since后面是一个时间点，动词用过去式。两周前的一天，与for two weeks 的两个星期这样14天相比是一个点。 一、延续性动词 延续性动词表示的动作不但可以延续，而且可以产生持久的影响。常见的这类动词有：be，have，keep，know，learn，lie，live，read，sing，sleep，stand，stay，wait，walk，watch等。延续性动词的用法很广，但常见于现在完成时中的句子中，且常与for，how，long，since等引导的表示一段时间的状语或状语从句连用。例如： 1．I have learned more than 1，000 Chinese words since I came to China． 自从来到中国，我已经学会了l，000多个汉字。 2．We have lived in Linqing since we came here．自从来到这儿，我们就一直住在临清。
3．I have kept the picture for about three years．这张画我保存了大约三年。 二、终止性动词 终止性动词又称为瞬间动词或非延续性动词，它表示的动作不能延续，也就是说动作一旦发生就立即结束，并产生某种结果。常见的这类动词有：accept，arrive，become，begin，borrow，break，buy，catch，close，come，die，end，fall，finish，get，give，go，join，leave，put，reach，receive，shut，start，stop等。终止性动词用在现在完成时要注意下面三点： （一）终止性动词可直接用来表示某一动作的完成。例如：1．They have reached Shanghai．他们已经到达了上海。2．Has he gone to London? 他已经到伦敦去了吗? （二）终止性动词表示的动作极其短暂，不能持续，所以，在现在完成时中一般不能和以since，for等引导的表示一段时间的状语连用。例如： 1．那老人已经死了一周了。The old man has died for a week．(误) 2．他三天前就已经来这儿了。He has come here since three days ago．(误) 在以上两句中，die和come都是终止性动词，可用于现在完成时，但不能与以
延续性与非延续性动词在现在完成时态中的使用 ☆有一些动词是瞬间动词，也叫非延续性动词，这些动词一发生就结束了，常见的有：come, go, arrive, reach, leave,begin, start, buy, join, die, borrow, get up, become, open, stop等。这些动词虽然可以用于现在完成时（说明某个动作的结果还存在），但由于它们不能延续，因此不能跟表示一段的时间状语连用。 e.g. Jim has come back. (正) Jim has come back for a month. (误) come back的动作不能延续一个月，因此错误。 ☆瞬间动词不可以用于有段时间的现在完成时态中，因此，若要解决这一问题，就应把它改为相应的延续性动词或短语，主要有以下几种： ①用相应的延续性动词 如：buy →have borrow →keep come/go/become →be put on →wear catch a cold →have a cold ②转换成be+名词 如：join →be a member of go to school →be a student ③转换成be+形容词或副词 如： die →be dead leave →be away begin →be on finish →be over fall asleep —be asleep open →be open get up →be up close →be closed ④转换成be+介词短语 如： come to/go to/arrive in (at)/get to/reach …→be in/at… join the army →be in the army(军队) e.g. I have borrowed the book.
