短暂性动词，延续性动词和现在完成时
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。
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；
★在否定句中，短暂性动词可以和表示一段时间的状语连用。
We haven’t heard from Jane for a long time.
★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。★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：
.I have received his letter for three days （×） I have received his letter.（√）
How long did she leave .（×） How long has she been away? (√) ★★★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 ★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 或者 It 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.
arrive →be here
begin(start)→be on
die →be dead
come back →be back
leave →be away (from)
fall ill(asleep)→be ill( asleep)
get up →be up
go out →be out
marry → be married finish →be over put on →wear 或be on open →be open close →be closed join →be in/ be a member of go to school →be a student borrow →keep buy/get →have dress → be dressed 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
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/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has gone to, has been to, has been in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）
（2）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。
★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.

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（短暂性动词与延续性动词）的用法 基本结构：主语+have/has+过去分词(done) ①肯定句：主语+have/has+过去分词+其他 ②否定句：主语+have/has+not+过去分词+其他 ③一般疑问句：Have/Has+主语+过去分词+其他 ④特殊疑问句：特殊疑问词+一般疑问句（have/has+主语+过去分词+其他） （1）现在完成时用来表示现在之前已发生过或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在. I have spent all of my money.(含义是:现在我没有钱花了.) Jane has laid the table.(含义是:现在桌子已经摆好了.) Michael has been ill.(含义是:现在仍然很虚弱) He has returned from abroad. (含义是:现在已在此地) （2）现在完成时可以用来表示发生在过去某一时刻的,持续到现在的动作（用行为动词表示）或状态（be动词表示）常与for（+时间段）,since（+时间点或过去时的句子）连用. Mary has been ill for three days. I have lived here since 1998. 注（超重要）：瞬间动词（buy,die,join,lose……）不能直接与for since 连用。要改变动词come-be go out-be out finish-be over open-be open die-be dead 1.have代替buy My brother has had(不能用has bought) this bike for almost four years. 2、用keep或have代替borrow I have kept(不能用have borrowed) the book for quite a few days. 3、用be替代become How long has your sister been a teacher? 4、用have a cold代替catch a cold Tom has had a cold since the day before yesterday. 5、用wear代替put on
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. The film began five minutes ago. ------The film has been on for five minutes. ------It has been five minutes since the film began. 用“be＋形容词”代终止性动词 1、be＋married代marry 2、be＋ill代fall (get) ill 3、be＋dead代die 4、be＋asleep代fall (get) asleep 5、be＋awake代wake/wake up 6、be＋open代open 7、be closed代close/shut 用“be＋副词”代终止性动词 1“be＋on”代start,begin 2“be＋up”代get up 3“be＋back(to)”代return to,come back to,go back to 4“be here (there)”代come(arrive,reach,get) here或go (arrive,reach,get) there等等 用“be＋介词短语”代终止性动词 1.“be in/at +地点”代替go to /come to 2.用be in the army 代替join the army 3.“be in/at +地点”代替move to

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 on die → be dead come here（back）→be here（back） leave → be away (from) fall ill(sick, asleep)→be ill(sick, asleep) get up→ be up go/ get out（there）→ be out（there） finish → be over put on → wear 或be on open → be open（keep sth. open） join → be in或be a member of…+组织机构 close → be closed go to school → be a student borrow →keep buy/get →have catch(a cold) → have(a cold)
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"
延续性动词与短暂性动词的用法英语中的动词，是学习中的重点，又是难点。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。 可以表示持续的行为或状态的动词，叫做“延续性动词”，也叫“持续性动词”，如：be, keep, have, like, study, live, etc. 有的表示短暂、瞬间性的动词，叫做“终止性动词”，也可叫“短暂性动词”，或“瞬间性动词”，如die, join, leave, become, return, reach, etc. 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-stric ken area. 但不可说：The Red Cross has already started for the earthquake-stric ken 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。 在多年的教学生涯中，发现学生对于如何解决这对矛盾不知所措，下面我来归纳一下解决这对矛盾的四种方法。 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 Americ a. 注意：以上两种办法适用于所有终止性动词。 3．用相应的形容词和副词代替终止性动词。 eg. Mr. Richard has been back from America for two years. 4．用延缓性动词代替终止性动词。 eg. He has gone to the Internet for six hours. (wrong) 应改为:He has been on the Internet for six hours. 但须注意：终止性动词的否定式可以和since 或for 引导的时间状语连用。因为终止性动词的否定表示的是一种可以延续的状态。 eg. I have heard from my friend in Africa for half a year. (wrong) I haven’t heard from my friend in Africa for half a year.. (right) 此外，终止性动词与延缓性动词在翻译上也不同，很易混淆。下面我再就终止性动词与延缓性动词的含义问题做一归纳：
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
现在完成时的否定动词能不能用延续性动词?我知道现在完成时的否定经常用短 暂性动词 比如i haven't seen her for 3days.1.是不是现在完成时的否定加短暂性动词表示的都是延续性的意思比如i haven't finished my homework yet.到目前为止我还没完成我的家庭作业。2.现在完成时的否定不可以跟延续性动词连用吗？比如i haven't lived there for 3 months.如果不对，那应该怎样表达？ 上面的句子应该都是对的，你也不用太怎么区分，只要记得在肯定句中要把短暂性动词转换成延续性动词就行了，否定句就用短暂性的。 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. 但是，不可以说：His father got ill for a week. 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. 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。 !!!!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。 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 o pen →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) move to → live in finish/end → be over come to → be in sit down → be seated marry → be married 等
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 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.

瞬间性动词变延续性动词 瞬间动词：形容一瞬间完成的动作：如，到达（arrive），开始（begin）等 短暂性动词：形容短时间完成的动作：如，吃（eat），等 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。 瞬间动词，也叫终止性、结束性动词。表示动作的结果，或表示短暂性、一次性的动作。如：close, leave, buy, join, become, begin, fall(掉下)，fall ill(病倒)，get to(know), come, go, see, hear, hear from, catch a cold等。这类动词可以用于完成时，但在一般情况下，不能加上表示一段时间的状语或疑问词。但是在否定句中，瞬间动词也可以和表示一段时间的状语、连词连用，它的含义是好长时间没进行这个动作了，没进行此动作的状态就可以延续。 a)用延续性动词代替终止性动词 1、用have代替buy My brother has had(不能用has bought) this bike for almost four years. 2、用keep或have代替borrow I have kept(不能用have borrowed) the book for quite a few days. 3、用be替代become How long has your sister been a teacher? 4、用have a cold代替catch a cold Tom has had a cold since the day before yesterday. 5、用wear代替put on b)用“be＋形容词”代终止性动词 1、be＋married代marry 2、be＋ill代fall (get) ill 3、be＋dead代die 4、be＋asleep代fall (get) asleep 5、be＋awake代wake/wake up 6、be＋gone代lose,die,sell,leave 7、be＋open代open 8、be closed代close/shut 9、be＋missing(gone,lost)代lose c)用“be＋副词”代终止性动词 1“be＋on”代start,begin 2“be＋up”代get up 3“be＋back(to)”代return to,come back to,go back to 4“be here (there)”代come(arrive,reach,get) here或go (arrive,reach,get) 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 to 2.用be in the army 代替join the army 3.“be in/at +地点”代替move to
