useful-短暂性动词,延续性动词和现在完成时
短暂性动词与延续性动词的用法
短暂性动词与延续性动词在现在完成时中的用法英语中的动词有多种分类法。
根据其有无含义，动词可分为实义动词和助动词；根据动词所表示的是动作还是状态，可以分为行为动词和状态动词；根据动词所表示的动作能否延缓，分为延续性动词和终止性动词。
英语中，按动词延续的时间长短，可将动词分为延续性动词和短暂性动词。
延续性动词如learn, study, work, play, wait，have,,live,teach,keep,like 等。
短暂性动词是非延续性动词，即动作一开始便结束的动词，又可称结束性动词，瞬间动词，如leave, begin, start, return, arrive, reach, die, marry, bear, see, hear, receive, buy, get, enter, take off, start off, come in, come back, take place, break out, put on, put down, go in 等。
终止性动词构成的现在完成时，不可以用表示一段时间的状语（如：since 和for引导的短语）来修饰，终止性动词构成的现在完成时，只表示动作发生的因果关系，不能表示动作的延续，因此不能用表示一段时间的状语来修饰。
如可以说：The Red Cross has already started for the earthquake-stricken area.但不可说：The Red Cross has already started for the earthquake-stricken area for three days.因为start是终止性动词, 它所表示的动作短促, 当红十字会出发时，start这个动作便结束了, 不可能延续两天。
1. 用ago时间状语短语来代替since或for引导的时间状语：eg. Mr. Richard has returned from America for two years. (wrong) Mr. Richard has returned from America since two years ago. (wrong) 应改为: He returned from America two years ago.2．用It is… since…复合句代替简单句eg. It has been/is two years since Mr. Richard returned from America.注意：以上两种办法适用于所有终止性动词。
短暂性动词及连续性动词辨析及用法
短暂性动词及连续性动词辨析及用法短暂性动词也称非延续性动词、瞬间动词，表示不能延续的动作发生后立即结束。
open,close,finish,begin,come,go,arrive,reach,getto,leave,move,borrow, buy,die,see,hear,fall,start,like,love,win,shot,enter,finish,lend,连续性动词live,run,stay,clean,play,hold,watch,teach,read,study,teach,eat,drink, write,dance, sing,smoke具体用法：1、终止性动词：表示不能延续的动作，即动作发生后立即结束。
如：begin,arrive,borrow,buy,break,close,come,fall,dic,finish,go,leave,len d,mary,reach,receive,open,sell,start,stop等。
终止性动词的肯定式是不能持续的，所以不能和表示一段时间的状语连用，而终止性的否定式就可以和表一段时间的状语连用，因为否定本身就是可以延续的。
如：have a cold是持续性动词，表示“状态”，可与表延续性的时间状语连用，不定冠词不能省略。
I′ve had a cold since my arrival（到达 n.）.I didn′t go to school because I had had a bad cold for days.catch a cold是短暂性动作，表“动态”：它不能和延续性时间状语连用，不定冠词“a”可有可无，catch可用take,get代替,1， Put on your coat,or you′ll catch/take/get a cold. 2，Take care not to get cold. ,但是，若cold前有形容词修饰时，则不定冠词不能省。
延续性与非延续性动词在现在完成时态中的使用
延续性与非延续性动词在现在完成时态中的使用
延续性动词和非延续性动词在现在完成时态中的使用有一些区别。
1.延续性动词：
延续性动词表示持续的动作或状态，常见的有live（住）、work
（工作）、study（学习）、wait（等待）等。
在现在完成时态中，延续
性动词通常用来表示一个动作或状态开始于过去，持续到现在，并且可能
会继续下去。
例如：
- I have lived in this city for 10 years.（我在这个城市住了
10年了。
）
2.非延续性动词：
非延续性动词表示瞬间动作或不可数的状态，常见的有arrive（到达）、die（死亡）、finish（完成）、know（知道）等。
在现在完成时
态中，非延续性动词通常用来表示一个动作已经完成或一个状态已经发生，没有持续的时间。
例如：
- She has arrived at the airport.（她已经到达了机场。
）
- The project has finished.（项目已经完成了。
）
- I have known him since childhood.（我从小就认识他了。
）
需要注意的是，有些动词既可以是延续性动词，也可以是非延续性动词，根据上下文来决定其使用方式。
比如，动词sleep（睡觉）可以是延
续性动词，表示持续的睡眠状态，也可以是非延续性动词，表示一次性的睡眠动作。
延续性动词和短暂性动词和现在完成时题目
He joined the Party 2 years ago.He has bee n in the Party for 2 years. I bought the book 5 days ago.子中的谓语动词一般为延续性动词。
但是，有些动词所表示的动作是短暂的，这类动词 叫做非延续性动词。
如： come, go, reach, arrive, leave, borrow, buy, jo in, die, begi n, start, finish 等。
在现在完成时的句子中，非延续性动词作谓语动词时，不能和表示一段时间的 状语连用。
表示动作的连续性，就要把非延续性动词转换成相应的延续性动词或短语，具 体转换如下：（要求记住）come/go/reach/arrivein/be leave 宀 beaway from, borrow keep, buy have, jo inbein/be a member of, die bedead, start/begin rbe finish/endbeer, openbe open (adj.), close be closed (adj.), marry Ice m eatci6/(go back to / returnto beback to go out be outbecome be get upbe dpi be dead fall asleep /get tot sleep be asleepienot have put on wear catch / get a coldhave acold ； get to know knovhave / has gone tohave been in注意：1. 非延续性动词可以在现在完成时的否定句中作谓语，并可以与 for , since 引导的时间状语连用，表示动作的延续过程。
例如：She hasn ' t bought anyew clothes since last year.2. 在现在完成时的肯定句中，非延续性动词作谓语时不能与 for , si nee 引导的表示一段时间的状语连用，但可以用其他句式来表示同一个意思。
延续性动词与短暂性动词 讲解与练习
短暂性动词，延续性动词与现在完成时姓名：_________短暂性动词（终止性动词），是指动作一旦发生就很快就结束。
它不能和一段时间连用。
这类动词有：go, come, arrive, leave, begin, start, join, marry 等；短暂性动词的肯定式不能与表示一段时间的for或since或how long等状语连用。
但是，在否定句中，短暂性动词可以和表示一段时间的状语连用。
延续性动词是指动作发生后还可以延续一段时间或者相当长的一段时间。
如：live, work, study, learn, sleep等，延续性动词可以和表示一段的时间状语连用。
值得注意的是，表示一段时间的状语除了“for+一段时间”外，还有since+n./从句（时间点），since+时间段+ago，疑问词how long ，in the past+时间段，all these+时间段，from…to（时间点）以及till/until+n./句子等等。
例如：1.这位老人已经死了十年了。
The old man has died for ten years.（×）（die“死”短暂性动词，不能与for+一段时间连用）The old man has been dead for ten years/since 10 years ago.（√）（die→be dead，die是短暂性动词，表示死的动作，这个动作很快就结束了，变成了表示状态的be dead，dead是die 的形容词，表示死了的状态，可以延续）2.我买了这块手表五年了。
I have bought this watch for five years.（×）（buy“买”短暂性动词，不能与for+一段时间连用）I have had this watch for five years/since 5 years ago. （√）（buy→have，buy这个动作在付完钱已经结束了，买完后是拥有have的状态，have 可以延续）3.我离开家乡已十年了。
短暂动词与延续性动词
短暂(duǎnzàn)动词与延续性动词短暂(duǎnzàn)动词与延续性动词1.现在(xiànzài)完成时的构成：have / has + 动词(dòngcí)的过去分词2.现在(xiànzài)完成时的用法：（1）表示某一动作或状态开始(kāishǐ)于过去并持续到现在现在。
（此种用法适用于延续性动词）I have been in Nanyang for around 5 years.我在南阳(nán yánɡ)大约有五年了。
（2）表示过去发生或已经完成的某一动作对现在造成的影响或结果（此种用法适用非延续性动词）。
I can’t go to see the movie now, because I have lost the ticket.现在我看不成电影了，因为我把票弄丢了。
3.现在完成时的标志：just, already, yet, ever, never,recently 近来 = in recent weeks (months, years)在最近的几周（月，年）里,nowadays, for + 一段时间，before (用于句子末尾); so far = up to now = till now; since + 过去某一具体时间点，since + 过去的一段时间 + ago， since + 一般过去时从句，ever since then = ever since = since then = since (自从那时起);in / over /during + the + past(last) + 一段时间。
Eg.On January 11,1998, Dr. Kataria organized the first “World Laughter Day” celebration in Mumbai, India. It was a huge success.The date was later changed to the first Sunday in May and it has been celebrated every year since.4.现在完成时中的特殊用法：短暂动词(dòngcí)的各种时态（包括现在完成时在内）不能和时间段连用(liányòng)，当它需要与时间段连用时需转换为延续性动词。
延续性动词和短暂性动词的区别
延续性动词和短暂性动词的区别延续性动词: live,run,stay,clean,play,hold,watch,teach,read,study,teach,eat,drink,write,dance, sing,smoke瞬间性动词:open,stop,like,love,die,win,close,shot,begin,start enter,finish1、终止性动词：表示不能延续的动作，即动作发生后立即结束。
如：begin,arrive,borrow,buy,break,close,come,fall,dic,finish,go,leave,lend,mary,reach,receive,open,sell ,start,stop 等。
终止性动词的肯定式是不能持续的，所以不能和表示一段时间的状语连用，而终止性的否定式就可以和表一段时间的状语连用，因为否定本身就是可以延续的。
如：have a cold是持续性动词，表示“状态”，可与表延续性的时间状语连用，不定冠词不能省略。
I′ve had a cold since my arrival（到达n.）.I didn′t go to school because I had had a bad cold for days.catch a cold是短暂性动作，表“动态”：它不能和延续性时间状语连用，不定冠词“a”可有可无，catch可用take,get代替。
Put on your coat,or you′ll catch/take/get a cold.Take care not to get cold.但是，若cold前有形容词修饰时，则不定冠词不能省。
如：Brown has taken a slight cold.注意下列句子：I have caught a cold for over a week.(×)I have had a cold for over a week.()2、延续性动词：表示可以延续一段时间的动作或状态。
初中英语中短暂性动词与延续性动词的用法
初中英语中短暂性动词与延续性动词的用法英语中，按动词延续的时间长短，可将动词分为延续性动词和短暂性动词。
延续性动词如learn, study, work, play, wait等。
短暂性动词是非延续性动词，即动作一开始便结束的动词，又可称结束性动词，瞬间动词，如come, go, begin, start, become, join, end, die, buy, arrive, reach, borrow, lend, get to know等。
一．短暂性动词与延续性动词在现在完成时中的用法：现在完成时中用法（一）：表示发生在过去，迄今已经完成，并对现在产生影响或产生结果的动作，常用ever, yet, already, just等状语，谓语动词既可是延续性动词，也可是短暂性动词。
如：She has just borrowed the book from the library.(borrow是短暂性动词)I have learned a little about Japanese. (learn 是延续性动词)现在完成时中用法（二）：表示始于过去某时并一直延续到现在的动作或状态，常与表示始于过去某一时刻并一直延续到现在的时间状语连用。
如：They have lived in Nantong since 1990. (live 是延续性动词）Mr. Black has worked here since he came to China.(work 是延续性动词)I have learned English for two and a half years.(learn 是延续性动词)所以，在现在完成时中用法（二）中，在表示持续一段时间的句子中，应将短暂性动词转化为相同意义的延续性动词或状态动词。
初中英语中常见的有：例如：1. His grandfather has died for ten years.(F)His grandfather has been dead for ten years.(T)2. My brother has joined the army for five years.(F)My brother has been in the army for five years.(T)My brother has been an armyman for ten years.(F)3. He has gone away for a week.(F) He has been away for a week.(T)4. The film has begun for fifteen minutes.(F)The film has been on for fifteen minutes.(T)但是，短暂性动词的现在完成时的否定形式可以表示一种延续的状态，因此可以和表示一段的状语连用。
短暂性动词和延续性动词
短暂性动词和延续性动词可以从字面上理解，持续的动作就是延续动词，反之就是瞬间动词（短暂动词），这个有这种感觉还是很好理解的，你看看下面的浅谈吧延续性动词:live,run,stay,clean,play,hold,watch,teach,read,study,teach ,eat,drink,write,dance, sing,smoke瞬间性动词:open,stop,like,love,die,win,close,shot,begin,startenter,finish1、终止性动词：表示不能延续的动作，即动作发生后立即结束。
如：begin,arrive,borrow,buy,break,close,come,fall,dic,finish,go ,leave,lend,mary,reach,receive,open,sell,start,stop等。
终止性动词的肯定式是不能持续的，所以不能和表示一段时间的状语连用，而终止性的否定式就可以和表一段时间的状语连用，因为否定本身就是可以延续的。
如：have a cold是持续性动词，表示“状态”，可与表延续性的时间状语连用，不定冠词不能省略。
I′ve had a cold since my arrival（到达n.）.I didn′t go to school because I had had a bad cold for days. catch a cold是短暂性动作，表“动态”：它不能和延续性时间状语连用，不定冠词“a”可有可无，catch可用take,get代替。
Put on your coat,or you′ll catch/take/get a cold.Take care not to get cold.但是，若cold前有形容词修饰时，则不定冠词不能省。
如：Brown has taken a slight cold.注意下列句子：I have caught a cold for over a week.(×)I have had a cold for over a week.( )2、延续性动词：表示可以延续一段时间的动作或状态。
“瞬间动词(也叫‘短暂动词’)” 和 “延续性动词”
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.
like live move
liked lived moved
一、A A A 型 原形、过去式和过去分词同形：
cost cut hit hurt set put shut read let
不规则动词的过去分词
三式相同
二、A B B 型 过去式和过去分词同形：

短暂性动词与延续性动词语法讲解
初中短暂性动词与延续性动词语法讲解根据有无含义，动词可分为实义动词和助动词；根据动词所表示的是动作还是状态，可以分为行为动词和状态动词；根据动词所表示的动作能否延缓，分为延续性动词和终止性动词。
（一）持续性动词: 表示动作通常是持续性的，如：live,run,stay,clean,play,hold,watch,teach,read,study,teach, eat,drink,write,dance, sing,smoke①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）瞬间性动词: 表示动作开始即停止，如：open,stop,like,love,die,win,close,shot,begin,startenter,finish,arrive,borrow,buy,break,close,come,fall,go,lea ve,lend,mary,reach,receive , sell,等。
1，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”2，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。
所以，“我买了这块手表5年了”，在汉语中说的通，但英语的表达就不能说：I have bought the watch for five years.buy sth ---- have sth (拥有)---have/has + had sth for…A: I have had the watch for 5 years.B: It is (has been) five years since I bought the watch. C: I bought it 5 years ago.同理，“borrow sth”“借书”在办理了相关的‘登记’手续后就结束了，不可能“借”几个星期或好几年的！汉语“这本书我已经借用了2星期了。

(完整版)现在完成时之短暂性动词与延续性动词用法
短暂性动词,延续性动词zai现在完成时中的应用短暂性动词,延续性动词和现在完成时短暂性动词是指动作一旦发生就立即结束.它不能和一段时间连用.这类动词有：go,come,arrive,leave,begin,start,join,marry等；短暂性动词的肯定式不能与表示一段时间的for或since或how long等状语连用.例如：His father got ill.I have received his letter.但是,不可以说：His father got ill for a week.I have received his letter for three days.在否定句中,短暂性动词可以和表示一段时间的状语连用.例如：We haven’t heard from Jane for a long time.I suppose something must have happened to her.延续性动词是指动作发生后还可以延续一段时间或者相当长的一段时间.如：live,work,study,learn,sleep等,延续性动词可以和表示一段的时间状语连用.值得注意的是,表示一段时间的状语除了“for+一段时间”外,还有since+n./从句（时间点）,since+时间段+ago,疑问词how long,in the past+时间段,all these+时间段,from…to（时间点）以及till/until+n./句子等等.例如：How long _______ your brother joined the army?A.hasB.hadC.is it sinceD.was there that通过审题,答案B和D很容易被排除,但是稍不注意便会选中答案A；殊不知how long 为一段时间的状语,不能与非延续性动词短语has joined连用,所以这题的正确答案是C.另外,动词的延续性与非延续性还体现在这两种句型中：延续性动词的肯定式+till/ until 短暂性动词的否定式+till/ until请看例句：We waited until he came.I didn’t go to bed until my father came back home last night.如果短暂性动词与表示一段时间的时间状语连用,必须将短暂性动词改为延续性动词.现归纳总结一下由非延续性动词到延续性动词的转换：arrive→be here begin(start)→be on die →be dead come back→be back leave →be away (from) fall ill(sick,asleep)→be ill(sick,asleep) get up→be up go out →be out finish →be over put on →wear 或be on open →be open join →be in或be a member of…close →be closed go to school→be a student borrow →keep buy/get →have catch(a cold)→have(a cold) get to know →know begin to study→study come to work→work move to →live in finish/end →be over come to →be in sit down →be seated marry →be married dress →be dressed等如：He has been a soldier for three years.他参军三年了.His father has been dead for two years.他父亲去世二年了.The film has been on for ten minutes.电影已开始十分钟了.We have studied English for three years.我们（开始）学英语已三年了.How long can I keep this book?这本书我可以借多长时间?除了用上面的转化形式之外,还可以用其他的表达形式：A.It is/ has been+时间+since……（动词用过去式）,B.主语+谓语（过去时）+时间+ago.例如：It’s five days since I received his letter.His father died three years ago.看一个句子可以用以下几种说法：他离开上海已经3天了.He left Shanghai three days ago.He has been away from Shanghai for three days.He has been away from Shanghai since three days ago. It is/ has been three days since he left Shanghai. Three days has passed since he left Shanghai.。

英语中，按动词延续的时间长短，可将动词分为延续性动词和短暂性动词。
延续性动词如learn, study, work, play, wait，have,,live,teach,keep,like 等。

终止性动词构成的现在完成时，不可以用表示一段时间的状语（如：since 和for引导的短语）来修饰，终止性动词构成的现在完成时，只表示动作发生的因果关系，不能表示动作的延续，因此不能用表示一段时间的状语来修饰。
如可以说：The Red Cross has already started for the earthquake-stricken area.但不可说：The Red Cross has already started for the earthquake-stricken area for three days.因为start是终止性动词, 它所表示的动作短促, 当红十字会出发时，start这个动作便结束了, 不可能延续两天。
1. 用ago时间状语短语来代替since或for引导的时间状语：eg. Mr. Richard has returned from America for two years. (wrong) Mr. Richard has returned from America since two years ago. (wrong) 应改为: He returned from America two years ago.2．用It is… since…复合句代替简单句eg. It has been/is two years since Mr. Richard returned from America.注意：以上两种办法适用于所有终止性动词。

短暂性动词
也称做点动词、非延续性动词或瞬间动词。
表示动作不能延续，只是一瞬间就结束的 动作。
常见的短暂性动词
come, go, arrive, reach, see, hear, close, open, leave, begin, start, lose, buy, fall, join, die, become,
短暂性动词用法全解
How are you getting to the airport？ 你将怎样去机场？ Bob is going with me to the hospital. Bob将和我一起去医院。
考例： I've won a holiday for two weeks to Florida. I____my mum.（NMET2001） A. am taking B. have taken C. take D.will have taken 分析：答案为A.用现在进行时代替一般将来时。
三、短暂性动词用于由when，while，as引导 的时间状语从句中
时间状语从句由when，while和as引起，主语和 从句中各有一个谓语动词，处理这类试题有个规 律可遵循：短暂性动词用一般过去时，持续性动 词用过去进行时。可理解为：持续时间短的动词 动作发生在持续时间较长的动词动作发生的过程 中。如：
My father worked at this factory until 1990. 我父亲在这家工厂一直工作到1990年。 （含义：到了1990年他就不在这家工厂工 作了）
持续性动词的否定式与until时间状语连用时，表 示该动词动作在until表示的时间之后发生，而在 此时间之前未发生。如：
考例： The price________，but I doubt whether it will remain so.（广东1999） A. went down B. will go down C. has gone down D. was going down
分析：go down意为“（物价等）下跌”，做不 及物动词使用，其动作短暂。答案为C.用现在完 成时，强调价格在说话前已经下跌，现在还没有 回升，所以就“怀疑今后是否仍会处于这种跌落 态势”。
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。

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。

短暂性动词，延续性动词和现在完成时短暂性动词是指动作一旦发生就立即结束。
它不能和一段时间连用。
这类动词有：go, come, arrive, leave, begin, start, join, marry 等；短暂性动词的肯定式不能与表示一段时间的for或since或how long等状语连用。
例如：His father got ill. I have received his letter.但是，不可以说：His father got ill for a week.I have received his letter for three days.在否定句中，短暂性动词可以和表示一段时间的状语连用。
例如：We haven’t heard from Jane for a long time.I suppose something must have happened to her.延续性动词是指动作发生后还可以延续一段时间或者相当长的一段时间。
如：live, work, study, learn, sleep等，延续性动词可以和表示一段的时间状语连用。
值得注意的是，表示一段时间的状语除了“for+一段时间”外，还有since+n./从句（时间点），since+时间段+ago，疑问词how long，in the past+时间段，all these+时间段，from…to（时间点）以及till/until+n./句子等等。
例如：How long _______ your brother joined the army?A. hasB. hadC. is it sinceD. was there that通过审题，答案B和D很容易被排除，但是稍不注意便会选中答案A；殊不知how long为一段时间的状语，不能与非延续性动词短语has joined连用，所以这题的正确答案是C。
另外，动词的延续性与非延续性还体现在这两种句型中：延续性动词的肯定式+till/ until 短暂性动词的否定式+till/ until请看例句：We waited until he came.I didn’t go to bed until my father came back home last night.如果短暂性动词与表示一段时间的时间状语连用，必须将短暂性动词改为延续性动词。
现归纳总结一下由非延续性动词到延续性动词的转换：arrive→be here begin(start)→be ondie →be dead come back→be backleave →be away (from)fall ill(sick, asleep)→be ill(sick, asleep)get up→be up go out →be outfinish →be over put on →wear 或be onopen →be open join →be in或be a member of…close →be closed go to school→be a studentborrow →kee p buy/get →havecatch(a cold)→ have(a cold)get to know →knowbegin to study→study come to work→workmove to → live in finish/end → be overcome to → be in sit down → be seatedmarry → be married dress → be dressed等如：He has been a soldier for three years. 他参军三年了。
His father has been dead for two years. 他父亲去世二年了。
The film has been on for ten minutes. 电影已开始十分钟了。
We have studied English for three years. 我们（开始）学英语已三年了。
How long can I keep this book? 这本书我可以借多长时间？除了用上面的转化形式之外，还可以用其他的表达形式：A. It is/ has been+时间+since……（动词用过去式），B. 主语+谓语（过去时）+时间+ago。
例如：It’s five days since I received his letter.His father died three years ago.看一个句子可以用以下几种说法：他离开上海已经3天了。
He left Shanghai three days ago.He has been away from Shanghai for three days.He has been away from Shanghai since three days ago.It is/ has been three days since he left Shanghai.Three days has passed since he left Shanghai.几点注意事项:（1）have been(to)与have gone( to)的区别：have been(to)表示“去过某地（现在已经回来了）”，可用于各人称；have gone(to)表示“去某地了（说话时某人不在当地）”，可能在去的路上，可能已在某地，也可能在回来的路上，总之，人不在这里。
常用第三人称作主语。
，前者可与once ,never, several times等连用，后者则不能。
如：They have been to Beijing twice. 他们去过北京两次。
He has gone to Beijing . 他去北京了。
注意比较下面几组句子的意义：He has gone to Amercia.（他到美国去了。
他不在这里）He has been to Amercia.（他去过美国。
现已回来）He has been in Shanghai.（他在上海呆过。
现在不在上海）He has been in shanghai for years.（他在上海多年。
现在还在上海）He has taught English.（他教过英语现在不教了）He has taught English for years.（他教英语多年了。
现在还在教）（2）如单纯表示一段时间，或强调一段时间，虽有since一词，也不必用完成时。
如：It is two years since his father died.=His father has been dead for two years. 他父亲去世已有三年了。
（3）终止性动词现在完成时的否定式，已变成一种可以延续的状态，因此可以和表示一段时间的状语连用。
如：I haven't left here since 1997. 自从1997年以来，我一直没有离开过这儿。
