延续性动词和非延续性动词
英语动词根据是否可以持续可分为两种,一种是延续性的(延续性动词),如如：learn，work，stand，lie，know，walk，keep， have，wait，watch，sing，read，sleep，live等；
一种是终止性的（瞬间动词/点动词/非延续性动词）, 如：leave，start，set out，arrive，reach，get to，begin， stop，shut，turn off，marry，put，put on，get up，wake，fall，join，receive， finish，end，complete，become，come，go，die，close，open，break，give， jump，buy，borrow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。
例如 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.( √ )
1．终止性动词的用法
1）终止性动词可用来表示某一动作的完成，因此可用于现在完成时。如：
The plane has arrived飞机到了。
I have finished my homework．我已完成了作业。
2）终止性动词表示的动作极其短暂，不能持续，所以其现在完成时（只限于肯定式）不能和表示一段时间的状语连用。如：
①他死了三年了。He has died for three years（×）．
②他来这儿三个月了。he has come here for three months（×）．
①②两句中的动词die和come都为终止性动词，它们可用于完成时，但不能同表示一段时间的状语for three years ／months连用。那这两句如何译成英语呢？我们可采用下列方法：
A．若保留for+时间段、since+时间点/从句、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。如：
①He has been dead for three years．
②He has been here for three months．
概括下来，将短暂性动词改为相应的延续性动词或短语和一段时间连用，其常用的方法有如下几种：
a.用相应的延续性动词替换的主要有：buy→have，borrow→ keep，come ／go ／become→be，catch ／get a cold→have a cold，get to know→know等。
b.be＋名词：join the Party ／League→be a Party ／League member， go to school→be a student，join the army→be a soldier等。
c.be＋形容词／副词：die→be dead，leave→be away（from），put on→be on，finish ／end→be over，begin ／start→be on，come→be here ／ in，fall asleep→be asleep，go out→be out等。
d.be＋介词短语：go to school→be in ／at school，join the army→ be in the army等。
e.去掉短语中的短暂性动词：get to know→know，come to work→work，begin to study→study等。
B.终止性动词要表示持续时, 可用以下方法:
将时间状语改为时间段 + ago,句中谓语动词用一般过去时.
例如I left Shanghai three days ago. =It is /has been three days since I left Shanghai.
C．用“It is ／has been ＋一段时间＋since（一般过去时）”结构。如：
①It is ／has been three years since he died．
②It is ／has been three months since he came here．
D．用“多长时间＋has passed ＋since（一般过去时）”结构。如：
①Three years has passed since he died．
②Three months has passed since he came here．
特殊用法
（1）not （do A)。。。until sb do B举行中“do A”一定是非延续性的
（do A)。。。until sb do B 句型中，“do A”一定是延续性的
例如：
We won't go（非延续性） to visit the Great Wall until the rain stops．直到雨停了我们才会去参观长城。
We were（延续性动词） in the Great Wall until the rain stoped
（2）在while（表示“一段时间”）引导的从句中，不能用终止性动词，但when 可以，因为when可表示“时间的点”，也可表示“一段时间”。如：
While I got to the village，it was dark（×）．
When I got to the village，it was dark（√）．
（3）终止性动词肯定式的完成时不能和how long连用。
例如：
How long have you borrow the book？（×）
可改用延续性动词或与when连用的一般过去时。
How long have you kept the book？（√）
When did you borrow the book？（√）

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.
动词概述 一、实义动词 ■①及物动词与不及物动词 根据后面是否带宾语，行为动词又可分为及物动词和不及物动词，及物动词。Vt. vi . They study hard. I know them well. 注：有的动词既可作及物动词，也可用作不及物动词。如： She sings very well. She sang an English song just now. 英语里有不少实义动词可以兼作及物动词和不及物动词。兼作及物动词和不及物动词时，____不变。试比较： Shall I begin at once? She began working as a librarian after she left school. When did they leave Chicago?They left last week. 短语： ■②动态动词和静态动词 动态动词表示动作，如give, take, work, run等；静态动词表示感觉、情感、内心世界、相互关系等，如know, exist, be, have, appear, prove, concern, hate, dislike, like, love, surprise, include, depend on, belong to, guess, suppose，imagine, believe, doubt, admire, envy等。 ■③延续性动词和非延续性动词 根据动作是否延续，行为动词又分为延续性动词和非延续性动词。如rain, live, work, learn等是延续性动词，go, come, leave, start, arrive, join, finish, end等是非延续性动词。 注：非延续性动词在肯定句中通常不与表示时间段连用的for短语连用。如：[译]他离开这里三天了。 [误]He has left here for three days. [正]He has been away from here for three days. [正]He left here three days ago. [正]It’s three days since he left. ■④限定动词与非限定动词
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
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.

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---be open, close--- be closed fall ill --- be ill, get up---be up, catch a cold --- have a cold, e here --- be here, go there --- be there, be e --- be, e back --- be back, fall asleep --- be asleep, get to/ arrive/reach --- be (in), leave --- be away, go (get) out →be out，put on→wear get married ---- be married 等。 例:The old man died 4 years ago. ----The old man has been dead for 4 years.

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.
中考英语短暂性动词与延续性动词相互转换讲练 中考英语短暂性动词与延续性动词相互转换对应表 语法讲解： 1.现在完成时表示过去发生的某一动作或存在的状态，一直持续到现在，并可以和以 for或since引导的表示一段时间的状语连用，也可以用在以“how long”提问的句子中，句子中的谓语动词一般为延续性动词。例： He has been away from Beijing for two years. = He left Beijing two years ago. When did the train arrive here? B. How long ____ the train ____ here? 2.在现在完成时的肯定句中，非延续性动词作谓语动词时，不能和表示一段时间的状语连用。但可以用其他句式来表示同一个意思。例： Lucy has come back. The old man died 4 years ago. = The old man has been dead for 4 years.
He has been away from Beijing for two years. = He left Beijing two years ago. = It is two years since he left Beijing. = Two years has passed since he left Beijing. 3.非延续性动词可以在现在完成时的否定句中作谓语，并可以与for，since引导的时间状语连用，表示动作的延续过程。例如： She h asn’t bought any new clothes since last year. I haven’t borrowed the book for a long time. 巩固习题： 1. When he arrived at the bus stop, the bus ________ for 20 minutes. A. has left B. had left C. has been away D. had been away 2.

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.

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进行时和现在完成进行时；延续性动词还可以用于现在完成时与表示"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 rained 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. -Then you've known each other for more than two years. -That's right. 三、终止性动词的用法特征 1.终止性动词可用来表示某一动作完成，因此可用于现在完成时。如： The train has arrived.火车到了。 Have you joined the computer group? 你加入电脑小组了吗？ 2.终止性动词表示的动作极其短暂，不能持续。因此，不可与表示一段时间的状语连用 (只限肯定式)。如：
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)
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
