瞬间动词转换成持续性动词(学习内容)

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.

现在完成时之瞬间动词转变为持续性动词

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.

现在完成时中瞬间动词变延续性动词总结

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.

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"

瞬间动词变延续性动词

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

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. It's six weeks ______ I met you last. A. when B. since C. before D. for （）3. Have you met Mr. Li ______？Ａ. just Ｂ. ago Ｃ.before Ｄ. a moment ago （）4. We ______ Xiao Li since she was a little girl. Ａ. know Ｂ. had known Ｃ. have known Ｄ. knew

延续性动词瞬间动词

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

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.

瞬间动词如何与延续性动词转换

瞬间动词如何与延续性动词转换瞬间动词如何与延续性动词转换在学习现在完成时的过程中，我们经常碰到类似这样的句子： 1）这辆自行车我已经买了五年了。 2）这位老人已经去世五年了。此时，有些同学就想当然的将之翻译为： 1)I have bought this bike for five years.（此句突出“买”的动作。言下之意，到现在还没有买到。） 2)The old man has died for five years.(此句突出“死”的动作，给人的感觉是“这位老人五年期间一直在死亡线上挣扎”。) 造成这种错误的主要原因是学习者在运用动词的过程中，将瞬间动词与延续性动词混为一谈。那么，什么是瞬间动词呢？简而言之，瞬间动词也叫短暂性动词或终止性动词。这种动词是指它们动作的开始也就意味着动作的结束，所以不能直接跟表示一段的时间状语连用。那么，如何使瞬间动词与表示一段时间的状语连用呢？此时，我们可以将这些词转换成意义相近的延续性词（组），从而间接表示其中的意思。这里试就常见的一些词及替换词作一简要小结：瞬间动词延续性动词 die be dead open (动词) be open （形容词） close (动词) be closed（形容词） get up be up fall asleep be asleep finish be over leave be away start/begin be on buy have

完成时态瞬间动词变延续性动词规则表(参考模板)

完成时态瞬间动词变延续性动词规则表延续性动词与终止性动词：动词按其动作发生的方式，动作发生过程的长短，分为延续性动词和终止性动词。延续性动词表示的动词是一种延续的动作，这种动词可以延续下去或产生持久的影响。如：learn，work，stand，lie，know，walk，keep，have，wait，watch，sing，read，sleep，live终止性动词也称非延续性动词、瞬间动词，表示的动作不能延续，即动作发生立即结束，产生某种结果。在有了某种结果之后，就不能再继续下去。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。 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。误：He has died for three years． ②他来这儿三个月了。误：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。

现在完成时难点瞬间动词转换成延续性动词.

现在完成时之瞬间动词转变成延续性动词一、for\since: 1)for+一段时间，常常可以发现for+数字，for three months for a long time for many years 2)Since+时间点，常常可以发现 a.since+月份，年份，表示时间的几点 b.since September since 1990 since 7 o’clock c.since+一段时间+ago； d.since two years ago since ten months ago c. since+ last+.... since last month since last year 二、现在完成时的结构式has\have done 请注意第三人称：she\he\人名...+has 三、当句子为肯定句，且句子中出现for\since的时候，句中的时态要用现在完成时，且句中的动词要用延续性动词。当句子为否定句时，句中的动词可以为瞬间动词，表示某个动作不发生的状态已经持续了...... 四、在有for\since的现在完成时的从句中，如何将瞬间动词转换成延续性动词以borrow——keep为例子 They borrowed it last week. They have kept it since last week. 分析： 1）我们已经知道现在完成时的标志就是has\have done，因此第一步就是看主

语，主语时They，我们选择have done。 2）因为borrow——keep.而keep——过去分词：kept，因此，have borrowed 就需要改成have kept. 3）Since后面只能接时间点，而last week就是一个时间点，因此，since后面直接填写last week。五、常考的瞬间动词：原形过去式过去分词动词原形动词过去分词 1.die--be dead die died died be dead been dead 2.borrow--keep borrow borrowed borrowed keep kept 3.leave--be away from leave left left be away from been away from 4.buy--have buy bought bought have had 5.begin--be(on) begin began begun be been 6.join--be a member of join joined joined be a member of been a member of be in join joined joined be in
