完成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。
那这两句如何译成英语呢？我们可采用下列方法：A．用能够表示持续状态的相应的延续性动词替换句中的终止性动词。
如：①He has been dead for three years．②He has been here for three months．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。

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。

现在完成时中瞬间动词变延续性动词总结
现在完成时中瞬间动词变延续性动词总结现在完成时是英语中一种重要的时态形式，用于表示过去发生的动作或事件对现在造成的影响或结果。
在现在完成时中，有两类常见的动词形式，即瞬间动词与延续性动词。
本文旨在总结现在完成时中瞬间动词如何变成延续性动词的规则和特点。
1. 延续性动词的定义：延续性动词表示一个动作或状态在时间上的延续，通常与时间段、频率或者持续性相联系。
例如：live（居住），work（工作），study（学习）等。
2. 瞬间动词的定义：瞬间动词表示一个动作或状态在时间上的瞬间发生，通常没有延续性。
例如：arrive（到达），finish（完成），buy （购买）等。
现在完成时中，将瞬间动词转变为延续性动词的方法如下：1. 加入持续性的时间状语：通过加入表示时间段的状语来表达动作的延续性。
例如：- He has been living in London for three years.（他已经在伦敦居住三年了。
）- She has been studying English since last month.（她从上个月开始一直在学习英语。
）2. 加入频率状语：通过加入表示动作频率的状语来表达延续性。
例如：- They have been playing tennis every weekend.（他们每个周末都在打网球。
）- I have been working out at the gym twice a week.（我每周在健身房锻炼两次。
）3. 加入表示动作状态的状语：通过加入表示动作状态的状语来表达延续性。
例如：- The team has been practicing hard for the upcoming tournament.（这个团队一直在为即将到来的比赛进行努力训练。
）- She has been studying diligently for her exams.（她为了考试一直努力学习。
现在完成时中短暂性动词变延续性动词归纳表
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: ⑴for+一段时间, 如：for 2 years; ⑵since从句, 如since he came here; since+过去时间点名词, 如since last year, since 5 days ago。
例: He has lived here for 6 years.You can keep the book for 5 days.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.三.延续性动词与非延续性动词之间的转换：（考试重点）例：He left five minutes ago. = He has been away for five minutes.这句话的意思是指他离开的动作是5分钟之前发生的，是过去时。
也就是说从他离开到现在已经有五分钟了，这个动作是延续的，要用现在完成时，并且要把原来的短暂性动词改为延续性动词。
一些短暂性动词及相应的延续性动词：arrive（get to /reach）→ be here (in)begin(start) → be ondie → be deadcome here（back）→be here（back）leave → be away (from)fall ill(sick, asleep)→be ill(sick, asleep)get up→ be upgo/ get out（there）→ be out（there）finish → be overput on → wear 或be onopen → be open（keep sth. open）join → be in或be a member of…+组织机构close → be closedgo to school → be a studentborrow →keepbuy/get →havecatch(a cold) → have(a cold)get to know → know begin to study → study come to work → work move to → live in finish → be over come to → be insit down → be seated marry → be married dress → be dressed become → be。
现在完成时中瞬间动词变延续性动词总结
现在完成时中瞬间动词变延续性动词总结在现代汉语中，现在完成时是表示过去发生的动作对现在产生的影响的一种时态。
而在现在完成时中，瞬间动词和延续性动词的用法有所不同。
本文将从理论和实践两个方面，对现在完成时中瞬间动词变延续性动词进行总结。
一、现在完成时的构成现在完成时由“助动词have/has + 过去分词”构成。
例如：I have seen that movie.(我已经看过那部电影了。
)二、瞬间动词变延续性动词1. 瞬间动词变成延续性动词的方法在现在完成时中，瞬间动词变为延续性动词的方法主要是通过加上“-ing”后缀。
例如：come -> coming;go -> going;see -> seeing等。
这种变化使得原本表示瞬间动作的动词变成了表示持续性动作的动词。
2. 延续性动词的使用场合延续性动词表示的动作在时间上没有明确的结束点，通常是持续性的。
在现在完成时中，延续性动词的使用场合主要包括以下几种：(1)表示一个长时间内一直在进行的动作。
例如：I have been studying English for 5 years.(我已经学习英语5年了。
)(2)表示一个习惯性的动作或者状态。
例如：She has been playing the piano since she was a child.(她从小就一直在弹钢琴。
)(3)表示一个与现在有关联的动作或状态。
例如：He has been living in this city for 3 years.(他已经在这个城市生活了3年了。
)三、结论现在完成时中瞬间动词变延续性动词是一种常见的语法现象。
通过掌握这种现象，我们可以更好地理解和使用现在完成时这一时态。
这也有助于我们提高自己的语言表达能力，使我们的语言更加地规范和准确。
现在完成时态的动词转换
延续性动词与瞬间动词的转换一、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。
二、瞬间动词与延续性动词的区别：1、用于完成时的区别1）延续动词表示经验、经历；2）瞬间动词表示行为的结果，不能与表示段的时间状语连用。
eg. 1.He has complet ed the work.他已完成了那项工作。
(表结果)2.I've known him since then.我从那时起就认识他了。
(表经历)2、用于till和until从句的差异1）延续动词用于肯定句，表示“做……，直到……”2）瞬间动词用于否定句，表示“到……，才……”eg. 1.He didn't come back until ten o'clock. 他到10点才回来。
2.He slept until ten o'clock.他一直睡到10点。
三、瞬间动词到延续性动词的转换：这里对一些词做一些总结：瞬间动词可转换的延续性动词（组）arrivebe herebegin/start be ondie be deadfall ill/sick/asleep be ill/sick/asleepget up be upgo out be outfinish be overput on wear或be onopen be open(adj.)join be in或bea memberof…close be closedgo to school be a studentborrowkeepbuy havecatch(a cold) have(a cold)get to know knowbegin to study studycome to work workget up be upleave be away from等如：1.He has been a soldier for three years. 他参军三年了。

现在完成时中瞬间动词变延续性动词总结
现在完成时中瞬间动词变延续性动词总结现在完成时（Present Perfect Tense）是英语语法中的一种时态，用来表示过去发生的动作或者状态与现在的关系。
在现在完成时中，瞬间动词（Instantaneous Verbs）可以变成延续性动词（Continuative Verbs），从而改变其表达的意义和使用方式。
本文将对现在完成时中瞬间动词变延续性动词的规则进行总结和归纳，以帮助读者更好地理解和运用。
一、瞬间动词（Instantaneous Verbs）瞬间动词是指表达一种在短时间内完成的动作或者状态的动词。
这类动词通常表示瞬间、短暂的行为或事件，其行为发生的时间很快，没有持续性。
以下是一些常见的瞬间动词：1. get（得到）2. arrive（到达）3. come（来）4. open（打开）5. close（关闭）6. finish（结束）7. start（开始）8. buy（购买）9. sell（出售）10. win（赢得）等等。
二、瞬间动词变延续性动词的规则现在完成时中，瞬间动词可以通过一些规则变成延续性动词，从而具有持续性。
一般而言，瞬间动词变延续性动词的方式有两种：添加辅助动词"have been"或使用"for"或"sice"引导的时间状语从句。
1. 添加辅助动词"have been"瞬间动词可以通过在其前面添加"have been"来表示一个动作或状态的持续性。
这种形式常常用于描述一个从过去某个时间开始一直延续到现在的动作或状态。
例如：- I have been living in this city for three years.（我在这个城市生活已经三年了。
）- He has been working on this project all day.（他从早到晚一直在做这个项目。
现在完成时中短暂性动词变延续性动词归纳表
延续性动词与非延续性动词及其转换之阿布丰王创作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.延续性动词暗示能够延续的动作,如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。
延续性动词可以与暗示时间段的状语连用。
暗示时间段的短语有: ⑴for+一段时间, 如：for 2 years; ⑵ since从句, 如 since he came here; since+过去时间点名词, 如 since last year, since 5 days ago。
例: He has lived here for 6 years.You can keep the book for 5 days.二.非延续性动词也称终止性动词、瞬间动词, 暗示不克不及延续的动作,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暗示时间点的状语连用，如：two years ago; at 5 o'clock;例:He died 5 years ago.三.延续性动词与非延续性动词之间的转换：（考试重点）例：He left five minutes ago. = He has been away for five minutes.这句话的意思是指他离开的动作是5分钟之前发生的，是过去时。
也就是说从他离开到现在已经有五分钟了，这个动作是延续的，要用现在完成时，而且要把原来的短暂性动词改为延续性动词。
一些短暂性动词及相应的延续性动词：arrive（get to /reach）→be here (in)begin(start)→be ondie →be deadcomehere（back）→be here（back）leave →be away (from)fall ill(sick, asleep)→be ill(sick, asleep)get up→be upgo/ get out（there）→be out（there）finish →be overput o n →wear 或be onopen →be open（keep sth. open）join →be in或be a member of…+组织机构close →be closedgo to school→be a studentborrow →keepbuy/get →havecatch(a cold)→ have(a cold)get to know →knowbegin to study→studycome to work→work move to → live in finish→ be over come to → be insit down → be seated marry → be married dress → be dressed become → be。
现在完成时--短暂性动词变延续性动词
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: ⑴for+一段时间, 如：for 2 years; ⑵since从句, 如since he came here; since+过去时间点名词, 如since last year, since 5 days ago。
例: He has lived here for 6 years.You can keep the book for 5 days.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.三.延续性动词与非延续性动词之间的转换：例：He left five minutes ago. = He has been away for five minutes.这句话的意思是指他离开的动作是5分钟之前发生的，是过去时。
也就是说从他离开到现在已经有五分钟了，这个动作是延续的，要用现在完成时，并且要把原来的短暂性动词改为延续性动词。
一些短暂性动词及相应的延续性动词：arrive（get to /reach）→ be here (in) begin(start) → be ondie → be deadcome here（back）→be here（back）leave → be away (from)fall ill(sick, asleep)→be ill(sick, asleep)get up→ be upgo/ get out（there）→ be out（there）finish → be overput on → wearopen → be open（join → be in或be a member of…+组织机构close → be closedgo to school → be a studentborrow →keepbuy/get →havecatch(a cold) → have(a cold)get to know → knowbegin to study → studycome to work → workmove to → live infinish/end → be overcome to → be inmarry → be marriedbecome → be。
瞬间动词变持续动词
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。
那这两句如何译成英语呢？我们可采用下列方法：A．用能够表示持续状态的相应的延续性动词替换句中的终止性动词。
如：①He has been dead for three years．②He has been here for three months．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：基本变化规则a)用延续性动词代替终止性动词1、用have代替buyMy brother has had(不能用has bought) this bike for almost four years.2、用keep或have代替borrowI have kept(不能用have borrowed) the book for quite a few days.3、用be替代becomeHow long has your sister been a teacher?4、用have a cold代替catch a coldTom has had a cold since the day before yesterday.5、用wear代替put onb)用“be＋形容词”代终止性动词1、be＋married代marry2、be＋ill代fall (get) ill3、be＋dead代die4、be＋asleep代fall (get) asleep5、be＋awake代wake/wake up6、be＋gone代lose,die,sell,leave7、be＋open代open 8、be closed代close/shut9、be＋missing(gone,lost)代losec)用“be＋副词”代终止性动词1“be＋on”代start,begin2“be＋up”代get up3“be＋back(to)”代return to,come back to,go back to代come(arrive,reach,get) here或go (arrive,reach,get) there等等4“be here (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 to2.用be in the army 代替join the army3.“be in/at +地点”代替move toe) “ be＋名词”代终止性动词join the Party ／League→be a Party ／League member，go to school→be a studentjoin the army→be a soldier等。
现在完成时难点瞬间动词转换成延续性动词
现在完成时难点瞬间动词转换成延续性动词for\since:for+一段时刻，常常能够发觉for+数字，for three months for a long time for many yearsSince+时刻点，常常能够发觉a. since+月份，年份，表示时刻的几点since September since 1990 since 7 o’clockb. since+一段时刻+ago；since two years ago s ince ten months agoc. since+ last+.... since last month s ince last year现在完成时的结构式has\have done 请注意第三人称：she\he\人名...+ has当句子为确信句，且居中显现for\since的时候，句中的时态要用现在完成时，且句中的动词要用连续性动词。
当句子为否定句时，句中的动词能够为瞬时动词，表示某个动作不发生的状态差不多连续了......在有for\since的现在完成时的从句中，如何将瞬时动词转换成连续性动词以borrow——keep为例子They borrowed it last week. They have kept it since last week.分析：我们差不多明白现在完成时的标志确实是has\have done，因此第一步确实是看主语，主语时They，我们选择have done。
因为borrow——keep.而keep——过去分词：kept，因此，have borrow ed就需要改成have kept.Since后面只能接时刻点，而last week确实是一个时刻点，因此，sin ce后面直截了当填写last week。
常考的瞬时动词：原形过去式过去分词动词原形动词过去分词die--be dead die died died be dead been deadborrow--keep borrow borrowed borrowed keep keptleave--be away from leave left left be aw ay from been away frombuy--have buy bought bought hav e hadbegin--be(on) begin began begun be beenjoin--be a member of join joined joined be a mem ber of been a member ofbe in join joined joinedbe in been inbecome--be become became become bebeenOpen\close--be open open opened opened be open been openfinish--be over finish finished finished be over been overput on--wear put put put wearworncatch a cold--have a cold catch caught caught havehadgo to--be in go went gone be in been inget to know--know get got got know knownArrive in\at--be in arrive arrived arrived be inbeen inMove\come\get to--be ingo out--be out go went gone bebeenMove\come\get to--be in be inbeen in举例Mr. Smith came to this school in September.Mr. Smith ___has____ ____been____ at this achool_____since___ S eptember.分析：1, come--came--come2, 本来应该是填写has come to，然而come to要转换成be in3, 而be的过去分词为been因此我们填写的内容为has been in4，因为句子中差不多有了at，因此我们只需要填写has been。
现在完成时态的动词转换
延续性动词与瞬间动词的转换一、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。
二、瞬间动词与延续性动词的区别：1、用于完成时的区别1）延续动词表示经验、经历；2）瞬间动词表示行为的结果，不能与表示段的时间状语连用。
eg. 1.He has completed the work.他已完成了那项工作。
(表结果)2.I've known him since then.我从那时起就认识他了。
(表经历)2、用于till和until从句的差异1）延续动词用于肯定句，表示“做……，直到……”2）瞬间动词用于否定句，表示“到……，才……”eg. 1.He didn't come back until ten o'clock. 他到10点才回来。
2.He slept until ten o'clock.他一直睡到10点。
三、瞬间动词到延续性动词的转换：这里对一些词做一些总结：瞬间动词可转换的延续性动词（组）arrive be herebegin/start be ondie be deadfall ill/sick/asleep be ill/sick/asleepget up be upgo out be outfinish be overput on wear或be onopen be open(adj.)join be in或bea member of…close be closedgo to school be a studentborrow keepbuy havecatch(a cold) have(a cold)get to know knowbegin to study studycome to work workget up be upleave be away from等如：1.He has been a soldier for three years. 他参军三年了。

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
been in
7.become--be become became become be been
8.Open\close--be open open opened opened be open been open
9.finish--be over finish finished finished be over been over
10.put on--wear put put put wear worn
11.catch a cold--have a cold catch caught caught have had
12.go to--be in go went gone be in been in
13.get to know--know get got got know known
14.Arrive in\at--be in arrive arrived arrived be in been in
15.Move\come\get to--be in
16.go out--be out go went gone be been
Move\come\get to--be in be in been in
举例
Mr. Smith came to this school in September.
Mr. Smith has been at this school since September.
分析：
1, come--came--come
2, 本来应该是填写has come to，但是come to要转换成be in 3, 而be的过去分词为been因此我们填写的内容为has been in 4，因为句子中已经有了at，所以我们只需要填写has been。
