意志性动词和非意志性动词
1.意志性动词：往往是表达主语可以出于某种目的或者是某个原因去做某件事情的动词.如：食べる（你肚子感到饿的时候，你可以在家里找点吃的东西吃啊，或者是去附近的便利店去买些动词吃啊）；书く（你有事情要通知你的朋友啊，便可以写邮件或者是写信告诉他们，或者是你觉得今天一天过的很有意义啊，便可以把一天发生的事情写下来）；还有：“话す、歌う、行く、歩く、泳ぐ、买う、売る、さがす、なおす、頼む…”这些动词都是你可以人为有意志地去做的，所以我们把这些动词叫做意志性动词。
2.非意志性动词：顾名思义，往往就不是受你主观所控制，你想去做就可以去做的，而这一类动词往往不是表达主观有意识地去做某件事情，而是表达一种事物产生的状态和结果的动词.具体可以分为下面几个方面。
（1）非生物做主语的动词：止まる（这个动词的主语往往是“车”“机械”等等都是一些非生物，而人做主语的时候，往往就不可以用这个动词了），还有：“冷える、なおる、割れる、开く、闭まる、かかる、付く…”
（2）表示自然现象的动词：（花が）咲く、（雨が）降る、（风が）吹く、昙る、（霜が）降りる…
（3）表示人体现象的动词：疲れる、（おなかが）すく、（のどが）渇く、（风邪を）ひく…
（4）表示人的心理现象的动词：あきる、呆れる、惯れる、惊く、喜ぶ…
延续性动词和短暂性动词的区别及用法
短暂动词当然可以用于进行时态。用什么时态和它是不是短暂动词没有什么关系。英语动词中，有些动词只用为表示状态；但有些动词，有时表示状态，有时又表示动作，遇到这样的动词，就要先分清它是作了状态动词呢，还是作了动作动词。如果是作了状态动词，就不用于进行体。 1、系动词表示状态，是状态动词，不用于进行体。 It is the Mid-autumn Festival today. --Let’s go to the suburbs to enjoy the moon. --It sounds a nice idea. Cui Yongyuan looks good-humoured. be动词也有用于进行体的时候。 2、感觉动词表示状态，是状态动词，不用于进行体。 They saw the plane splashing on the top of the hill. The medicine tastes a little bitter. Don’t you hear me? I’m saying. 常见的还有：feel, keep, notice, smell, etc. 如果表示强调、短暂、一时的状态，也可以用于进行体： The weather is keeping fine these days. I didn’t expect he is being terribly friendly to me. My back is hurting. 3、表示思想活动的动词也是状态动词，不用于进行体。 I know nothing about the market for the festival. I wonder why they have made a decision to go on with the work during the festival. What do you mean? 常见的还有：Admit, agree, appreciate, believe, care, consider, dislike, disbelieve, doubt, expect, find (=consider), forget, guess, imagine, realize, regret, remember, see (understand), suppose, think etc. 如果表示说话人的情感，也会用于进行体： --I am loving the Beijing Opera, aren’t you? --No. Frankly, I am hating it. 4、动词表示愿望、需要时也是一种状态，不用于进行体。 I hope we can have 7 days off over the festival. We all desire health and happiness. What you said requires careful thought. 常见的还有：need, want, wish etc. 5、存在与所属也是一种状态，表示存在与所属的动词也被看作是状态动词，不用于进行体。 He owed his success to luck more than to capacity. The two sides have reached a partial agreement, but several differences still exist between them. 常见的还有：belong to, compare, concern, consist of, depend on, equal, have, include, involve, keep, own, possess, result, stand for etc. 动词have表示所属，但更多的情形是构成短语表示动作，这时，它就可以用于进行体了： He has a good memory. (have在此例中表示possess, owe拥有，是状态)
初三英语延续性动词与非延续性动词及其转换专题辅导
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

瞬间性动词与延续性动词(新)
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. 五、终止性动词的否定式与until/till连用，构成"not+终止性动词+until/till ..."的句型，意为"
瞬间动词与延续性动词
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.

延续性动词和非延续性动词
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
延续性动词和终止性动词的用法
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 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+ 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? 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,arrive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. 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, 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,get married---be married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 Party for 2 years. I bought the book 5 days ago. ---- I have had the book for 5 days.
延续性动词和短暂性动词转换归纳
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.
延续性动词和终止性动词的区别及用法
延续性动词和终止性动词的区别及用法 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. -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： (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.
常用短暂性动词与延续性动词及其例句
一、现在完成时的谓语动词如果是短暂性动词，通常不能与表示一段时间的短语及短语（或从句）等连用。应将短暂性动词改为相应的延续性动词。如： 1、This factory opened twenty years ago. This factory has been open for twenty years. 2、Miss Gao left an hour ago. Miss Gao has been away for an hour.
3、Her teacher has been a Party member for 3 years. Her teacher joined the Party 3 years ago. 4、The film began two minutes ago. The film has been on since two minutes ago. 5、He bought the bike two years ago. He has had the bike for two years. 6、The old man died ten years ago. The old man has been dead for ten years. 7、He came back 3 days ago. He has been back for 3 days. 8、I left my hometown 10 years ago. I have been away from my hometown for 10 years. 9、They got married 13 year ago. They have been married for 13 years. 10、I borrowed the book a week ago. I have kept the book for a week. How long have you kept the book? 注：在否定句中，短暂性动词可以和表示一段时间的状语连用。 I haven’t borrowed the book for a long time. 我好长时间没有借过这一本书了。

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.360docs.net/doc/f713820502.html,e here—be here https://www.360docs.net/doc/f713820502.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．
延续性动词和终止性动词
★延续性动词和终止性动词。 动词可分为：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, walk, 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。 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, begin, come, go, move, borrow, lend, buy, arrive等。 ★when, while,用法 一、when 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。 主句when 引导的时间状语从句 2、Were you writing when the teacher came in? 老师进来的时候，你在写信吗？ 主句when 引导的时间状语从句 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。when 引导的时间状语从句主句 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，通常主句用过去进行时，从句用一般过去时。 二、while 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。 while 引导的时间状语从句主句 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。 主句while 引导的时间状语从句 在while引导的时间状语从句中，其谓语动词只能是延续性的，其引导的从句多用进行时态。 三、when/while都可做并列连词．when表示(这时，突然)，while表对比，译为”然而” I was going downstairs when the telephone rang. 我正要下楼，这时电话铃响了。 Lucy is in blue while Lily is in green.

持续动词与瞬间动词
持续动词与瞬间动词 英语的行为动词有持续性动词和瞬间性动词之分，使用中应注意两者的区别。 持续性动词表示一个动作可持续一段时间，此类动词有do, live, have, keep, wear, sleep, wait, work, play, stay, know, sing, dance, write, study, rest, talk, walk等. 瞬时性动词表示不能持续的动作，这种动作发生后立即结束，此类动词有 open, close, finish, begin, come, go, arrive, reach, leave, move, borrow, buy, die, lend, join, catch, get, win, fail等 一、持续性动词 表示一个动作可以持续一段时间或更长时间。常见的有study, play, do, read, learn, drive, write, clean, slean, sleep, speak, talk, wait, fly, stay, write, sit, stand, lie, keep等。 二、瞬间性动词 表示一个动作发生在一瞬间，非常短暂。亦称终止性动词。常见的有begin, start, finish, go, come, leave, find, get up, arrive, reach, get to, enter, hear, stop, open, close, become, buy, borrow, lend, happen, join, lose, renew, die, take away, put up, set out, put on, get on/off等。 以上已集中了初中教材的大部分持续性动词及瞬间性动词。 三、用法 1、以上两类动词都能用于现在完成时，表示动作到现在为止已结束，例如： He has studied English for three years.（他学英语已有3年了。） He has joined the Party.（他已入党了。） Mum isn’t at home. She has gone to the library.（妈妈不在家，她去图书馆了。） 2、持续性动词在完成时中能与表示持续一段时间的状语连用，而瞬间性动词则不能。例如： His parents talked with the teacher for half an hour.（他的父母跟老师谈了半个小时。） My mother has lain in bde for 3 days.（我母亲生病卧床已经三天了。）My parents have lived in Shanghai since 1950.（我父母亲从1950年起就住

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.
