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。

初三英语总复习之——瞬间动词到延续性动词的转化.
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。
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嘿，伙计们！今天我们来聊聊一个很有趣的话题：现在完成时中瞬间动词变延续性动词。
你是不是觉得这个话题有点儿高级？别担心，我会用最简单的语言和你们分享这个知识点，让我们一起来看看吧！我们来了解一下什么是现在完成时。
现在完成时是用来表示过去发生的事情对现在造成的影响，或者说过去发生的事情一直持续到现在。
比如说，“我已经吃过饭了。
”这句话就是用现在完成时表示的，因为“吃”这个动作对现在造成了影响，也就是说我现在已经不饿了。
那么，现在完成时中的瞬间动词是什么意思呢？瞬间动词是指那些表示动作或状态发生得很突然、很短暂的动词。
比如说，“我突然想起了我还有一个作业没有写。
”这里的“想起”就是一个瞬间动词，因为它表示的动作发生得非常突然。
接下来，我们要讨论的是为什么瞬间动词会变成延续性动词。
这是因为瞬间动词表示的动作通常是短暂的，但是有时候我们想要表达的动作并不是短暂的，而是持续性的。
这时候，我们就需要把瞬间动词变成延续性动词。
比如说，“我突然想起了我还有一个作业没有写。
”我们可以把这个瞬间动词变成延续性动词，变成“我突然意识到我还有一个作业没有写。
”这样一来，原本短暂的动作就变成了持续性的动作。
那么，怎么把瞬间动词变成延续性动词呢？其实很简单，我们只需要在瞬间动词后面加上一个表示持续性的词就可以了。
比如说，“我突然想起了我还有一个作业没有写。
”我们可以加上“意识到”，变成“我突然意识到我还有一个作业没有写。
”这样一来，原本短暂的动作就变成了持续性的动作。
好了，现在我们已经知道了如何把瞬间动词变成延续性动词。
下面我们来看一些例子：例1:我突然想起了我还有一个报告没有写。
在这个例子里，“想起”是一个瞬间动词，表示的动作发生得很快。
我们可以把这个瞬间动词变成延续性动词，变成“我突然意识到我还有一个报告没有写。
”这样一来，原本短暂的动作就变成了持续性的动作。
例2:他突然发现自己犯了一个错误。

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)。

延续性动词和瞬间动词的相互转换
延续性动词和瞬间动词的相互转换1.动词，按动作发生方式和发生过程长短，可分为延续性动词和瞬间动词。
①延续性动词，指动作发生后，可以长时间延续或产生持久影响。
learn学习live居住sleep睡觉rain下雨②瞬间动词，指动作发生后很快结束，持续时间极短。
也称短暂性动词。
borrow借arrive到达give给happen发生2.现在完成时的谓语①若是延续性动词，须接“段”时间状语，才符合动作可延续的特征。
My family have lived in Hainan for several years.②若是瞬间动词，通常无时间状语或接点时间状语、模糊的时间状语。
不可接“段”时间状语，因为动作不能延续。
He has just left Beijing for Singapore.他刚刚离开北京去新加坡。
3.延续性动词与瞬间动词的转换。
①瞬间动词不能接“段”时间状语。
但可把瞬间动词转换为意义相当的延续性动词或短语，便可接“段”时间状语。
He left five minutes ago.他5分钟之前离开了。
=He has been away for five minutes.他离开有5分钟了。
不能说：He has left for five minutes.×（leave是瞬间动词，强调动作。
be away属延续性动词，强调状态。
leave须转换为be away，才能接“段”时间状语。
）②瞬间动词转换为意义相当的延续性动词，有以下几种方式。
✬转换成相应的延续性动词buy→have买borrow→keep借become→be变得put on→wear穿catch a cold→have a cold感冒move to→live in搬到I borrowed the magazine two days ago.→I have kept the magazine for two days.The baby caught a cold last week.→The baby has had a cold since last week.✬转换成“be+名词”join→be a member of加入go to school→be a student上学Jim joined the band last month.→Jim has been a member of the band since last month.✬转换成“be+形容词/副词”die→be dead死leave→be away(from)离开begin→be on开始finish→be over结束fall asleep→be asleep入睡fall ill→be ill生病get up→be up起床open→be open开close→be closed关The shark died hours ago.鲨鱼几个小时前死亡了。

④我成为一个学生两年多了.
I have been a student for over two years. I became a student two years ago.
⑤ Mr Black死了三年了。
Mr Black has been dead for three years. Mr Black died three years ago.
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。如可说“He has left.”但 不能说“He has left for three years.” 如果要表达 “他已走了三年了”可用以下几种表达法： 一、用ago,使用一般过去时。
He left here three years ago. 二、用“It is +一段时间＋since ＋一般过去时从句 ”
been dead
e.g.他自从1985就参军了。 He has been a soldier since 1985. He has been in the army since 1985.
一般过去时态和现在完成时态可以构成同义句
①.我们买这本书三年了.
We have had the book for three years. We bought the book three years ago.

瞬间动词与延续性动词
Practice: 瞬间动词和延续性动词、状态句型转化练习（1）
1、你来晚了，电影已放了10分钟了。
A: You are late. The film has been on for 10 minutes.
B: You are late. It is ten minutes since the film
③自从上星期以来,我就借了这本书. I have kept the book since last week. I borrowed the book last week.
④我成为一个学生两年多了. I have been a student for over two years. I became a student two years ago.
“瞬间动词(也叫‘短暂动词’)” 和 “延续性动词”
1、瞬间动词：
从“开始发生”到 “结束/终止”： 几乎同时或在极短的时间里（如‘几秒钟/几分钟内’）就 完成了“开始—结束”的过程，如 “Close the door”, “Open the door”
有些瞬间动词的“开始—结束的过程” 可能稍微长一些， 但也不会很长的，如, “buy sth（买下）”：付了款、拿了发票即完成了。
“我两周前 （borrowed it），（在归还前）现在 它还在我手里（I still have it or I’m still reading it.）
Right or Wrong?
A: I have borrowed the book for two weeks.
B: I have had / kept it for two weeks.
规则动词的过去分词
work visit ask play stay
延续性动词与瞬间动词的转换
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（比如for或since引导的表示一段时间的状语或用how long 来提问）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，我们可以将当短暂性动词与一段时间连用时，就要转化为延续性动词。
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，不能与表示一段的时间状语连用。
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。
如：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 twomonths。
他已经入党/团两个月了。
The film has started/begun.The film has been on/ lasted since 5 minutes ago.电影已经开始5分钟了。
瞬间动词到延续性动词的转换
瞬间动词到延续性动词的转换延续性动词可直接与表段时间的since, for 短语连用。
（注：for 接表示一段时间的词。
如：for three years, for a long time；since 接时间点或过去从句。
如：since three years ago， since he came to this city。
） I have kept the book for two weeks. 这本书我借了两周了。
在肯定句中,非延续性动词若要与段时间连用，可通过以下几种形式：1. 用状态动词代替非延续性动词或用系表结构代替句中的谓语。
常见的转化有：join→be in / a member of, begin→be on, leave→be away (from), die→be dead, borrow→keep, buy→have 等。
例如：The film has been on for an hour. 电影已经上演一个小时了。
2. 用“... ago”代替原句时间状语。
例如：The film has been on for an hour. = The film began an hour ago.3. 用“It’s / has been + 段时间 + since + 从句.”代替原句。
例如：Tom has had the book since two years ago. = It’s two years since Tom bought the book.1. 非延续性动词不能用于“how long ...”引导的特殊疑问句中。
例如：误：How long may I borrow the bike? （要将borrow 改为keep）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be a 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。

表示一段时间的for和since短语，两者可相互转换。
与for, since 短语连用的现在完成时态中的动词应为延续性动词。
某些非延续性动词也可以用于现在完成时的句子中，但如果有表
示一段时间的状语，这些动词必须用延续性动词代替。
如下，
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 Party for 2 years. I bought the book 5 days ago. ---- I have had the book for 5 days.
