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．

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.
中考英语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 不能与时间段连用。如:open, die, close, begin, finish, e, go, move, borrow, lend, buy等。 如果要与时间段连用，就把它转为延续性动词使用。 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. 但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---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. He joined the Party 2 years ago. -----He has been in the Party for 2 years. I bought the book 5 days ago. ---- I have had the book for 5 days. 补充练习： 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. I ______ the League for 5 years so far. A. joined B. have joined C. have been in 3.The factory ________ since the February of 1988.

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. -Then you've known each other for more than two years.
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.

A. have returned B. have been back C. returned 10. How long _______ he ________ ? A. died B. has, died C. has, been dead 11. He ______ at eight yesterday afternoon.
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.

(完整版)瞬间性动词 与延续性动词(新) -CAL-FENGHAI-(2020YEAR-YICAI)_JINGBIAN
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：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: 1.for+一段时间, eg: for 2 years; for a long time等 2.since从句,since he came here; 3.since+时间点+ago,eg：since last year, since 5 days ago; 4. how long; 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。 如果要与for+ 时间段，since+年份，since+时间段+ago，how long连用时，瞬间性动词要变延续性动词。 三.延续性动词与非延续性动词之间的转换：
例：（1）他死了三年了。 误：He has died for three years. 正：He has been dead for three years. 正：He died three years ago. 正：It is three years since he died. 正：Three years has passed since he died. (2) 他来这儿五天了。 误：He has come here for five days. 正：He has been here for five days. 正：He came here five days ago. 正：It is five days since he came here. 正：Five days has passed since he came here. (1)、(2)句中的die、come为终止性动词，不能与表示"段时间"的状语连用。那么，应如何正确表达呢？可以采用下面的四种方法： (1)将句中终止性动词转换为相应的延续性动词, 如上面两例中的第一种正确表达方式. (2)将句中表示"段时间"的状语改为表示过去确定时间的状语，如下面两例中的第二种正确表达 方式。 (3)用句型"It is+段时间+since..."表达原意，如上面两例中的第三种正确表达方式。 (4)用句型"时间+has passed+since..."表达原意，如上面两例中的第四种正确表达方式。 四、终止性动词可用于现在完成时否定式中，成为可以延续的状态，因而可与表示一段时间的 状语连用。 如:1.He hasn't left here since 1986. 2.I haven't heard from my father for two weeks.
瞬间性动词变延续性动词 瞬间动词：形容一瞬间完成的动作：如，到达（arrive），开始（begin）等 短暂性动词：形容短时间完成的动作：如，吃（eat），等 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。 瞬间动词，也叫终止性、结束性动词。表示动作的结果，或表示短暂性、一次性的动作。如：close, leave, buy, join, become, begin, fall(掉下)，fall ill(病倒)，get to(know), come, go, see, hear, hear from, catch a cold等。这类动词可以用于完成时，但在一般情况下，不能加上表示一段时间的状语或疑问词。但是在否定句中，瞬间动词也可以和表示一段时间的状语、连词连用，它的含义是好长时间没进行这个动作了，没进行此动作的状态就可以延续。 a)用延续性动词代替终止性动词 1、用have代替buy My brother has had(不能用has bought) this bike for almost four years. 2、用keep或have代替borrow I have kept(不能用have borrowed) the book for quite a few days. 3、用be替代become How long has your sister been a teacher? 4、用have a cold代替catch a cold Tom has had a cold since the day before yesterday. 5、用wear代替put on b)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＋gone代lose,die,sell,leave 7、be＋open代open 8、be closed代close/shut 9、be＋missing(gone,lost)代lose c)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 d)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
延续性和非延续性动词 一.延续性动词 表示行为或过程能持久继续下去或能产生持久的影响。如contain, have, hold, lie, live, make, sit, rain, sleep, stand, study, wait, wear, work等。也包括表示状态感情思维类的，如believe, consider, hate, hope, know, like, love, respect, think, understand, wish等。延续性动词可以与表示时间段的状语连用。 ①可以和“段时间”状语连用 表示“段时间”短语,如for +段时间(for 2 years, for a long time ,for the spring,)；since从句(since he came here)或since+点时间(since last year, since 5 days ago, since leaving school)；how long; always；all day long；until April 等。 This book has been lying on the desk for a week.这本书已经在桌子上放一个星期了。(错This book has been put on the desk for a week. 其中put on是瞬间动词) Men wear suits when they attend meetings.男人在开会时穿西装。(错Men put on suits when they attend meetings.其中put on是瞬间动词) She has worked hard for a year.她一年来一直努力工作。(错She has worked hard a year ago. 其中a year ago是点时间) ②不能和“点时间”状语连用 如果用延续性动词表示一瞬间动作,可以借助come, begin, get等非延续性动词来表示。 It began to rain at eight yesterday morning.昨早8点开始下雨了。(错It rained at eight yesterday morning. 其中rain为延续性动词,而at eight 表示“点时间”,前后显然矛盾) When did you get to know Jack? -Two years ago.你什么时候认识杰克的？两年前。(when可接段时间也可以接点时间) How did you come to know it?你怎么知道这件事的？ After lunch it began to rain.午饭后天下起雨来。 I can't get used to the wet weather.我不能习惯于这潮湿的天气。 ③可用于各种时态,表示动作延续 We will stay in Dalian for the whole summer.我们一夏天将留在大连(一般时) What are you doing? I'm doing some dishes. 你在干什么？我在洗碗(进行时) They have been watching TV for the whole evening. 他们整晚上一直在看电视(完成进行时) ④表示状态思维感情等延续性动词，一般不可用于进行时。 I like his ideas.我喜欢他的主意。(错I'm liking his ideas) I understood what he said.我理解他说的话。(错I was understanding what he said.) 表示状态感情思维动词如用进行时则不表示正在“进行”,而表示有三种情况：(一是即将发生的动作；二是感情和强调情况的暂时性；三是一时的表现)： She is having a holiday next Sunday.她下个星期天度假(即将动作) How are you feeling today?你今天感觉怎样？(亲切感情) You are being a good child today.你今天是个乖孩子(一时表现) 二.非延续性动词
