现在完成时之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 col d，get to know→know等。
b．be＋名词：join the Party ／League→be a Party ／League member，go to school→be a student，join the army→be a soldier等。
c．be＋形容词／副词：die→be dead，leave→be away（from），put on→be on，finish ／end→be over，begin ／start→be on，come→be here ／in，fall a sleep→be asleep，go out→be out等。
d．be＋介词短语：go to school→be in ／at school，join the army→ be in the army 等。
e．去掉短语中的短暂性动词：get to know→know，come to work→work，begin to study→study
B．把误句中表示一段时间的状语改为表示过去时间的状语，原动词的完成时改为过去时。
①He died three years ago．
②He came here three months ago．
C．用“It is ／has been ＋一段时间＋since（一般过去时）”结构。如：
①It is ／has been three years since he died．
②It is ／has been three months since he came here．
D．用“多长时间＋has passed ＋since（一般过去时）”结构。如：
①Three years has passed since he died．
②Three months has passed since he came here．
3）终止性动词现在完成时的否定式，已成为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 heard from him for two weeks．我已两个星期没收到他的信了。
He hasn't left here since 1990．自从1990年以来，他一直没有离开过这儿。
4）终止性动词的否定式同until一起连用，构成“not．．．until”结构，意为“直到……才……”，表示这个动作直到until所表达的时间到来时才发生。如：
We won't go to visit the Great Wall until the rain stops．直到雨停了我们才会去参观长城。
—When did you go to bed last night？昨晚你几点钟点上床睡觉的？
—I didn't go to bed until my father got home．直到我爸爸到家我才上床睡觉。
5）在while（表示“一段时间”）引导的从句中，不能用终止性动词，但when可以，因为when可表示“时间的点”，也可表示“一段时间”。如：
误：While I got to the village，it was dark．
正：When I got to the village，it was dark．
6）终止性动词肯定式的完成时不能和how long连用。如：
误：How long have you borrow the book？
可改用延续性动词或与when连用的一般过去时。
正：How long have you kept the book？
正：When did you borrow the book？
2．延续性动词的用法
1）延续性动词可以用于现在完成时，其完成时可以同一段时间状语连用。如：I have waited for him for nearly two hours．我等他快两个小时了。
2）终止性动词不能和表一段时间的状语连用。同样，延续性动词也不能和表示短暂时间的时间点连用。如：
误：It rained at eight yesterday morning．
rain为延续性动词，而at eight是表示时间点的状语，显然矛盾。如果要用延续性动词表示一瞬间的行为，可以借助come，get，begin等终止性动词来表达。上句可改为：
It began to rain at eight yesterday morning．
3）在until引导的时间状语从句中，若主句的谓语动词是持续性动词，既可以用肯定形式，也可以用否定形式，但句子含义不同。试比较：
She listened to the radio until her father came back．她一直听收音机到她父亲回来。She didn't listen to the radio until her father came back．直到她父亲回来才听收音机。
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

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)
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
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
持续动词与瞬间动词 英语的行为动词有持续性动词和瞬间性动词之分，使用中应注意两者的区别。 持续性动词表示一个动作可持续一段时间，此类动词有do, live, have, keep, wear, sleep, wait, work, play, stay, know, sing, dance, write, study, rest, talk, walk等. 瞬时性动词表示不能持续的动作，这种动作发生后立即结束，此类动词有open, close, finish, begin, come, go, arrive, reach, leave, move, borrow, buy, die, lend, join, catch, get, win, fail等 一、持续性动词 表示一个动作可以持续一段时间或更长时间。常见的有study, play, do, read, learn, drive, write, clean, slean, sleep, speak, talk, wait, fly, stay, write, sit, stand, lie, keep等。 二、瞬间性动词 表示一个动作发生在一瞬间，非常短暂。亦称终止性动词。常见的有begin, start, finish, go, come, leave, find, get up, arrive, reach, get to, enter, hear, stop, open, close, become, buy, borrow, lend, happen, join, lose, renew, die, take away, put up, set out, put on, get on/off等。 以上已集中了初中教材的大部分持续性动词及瞬间性动词。 三、用法 1、持续性动词在完成时中能与表示持续一段时间的状语连用，而瞬间性动词则不能。例如：His parents talked with the teacher for half an hour.（他的父母跟老师谈了半个小时。） My mother has lain in bed for 3 days.（我母亲生病卧床已经三天了。） My parents have lived in Shanghai since 1950.（我父母亲从1950年起就住在上海了。） 2、瞬间性动词在完成时中如要与表示持续一段时间的状语连用，通常的方法： （1）用意思相当的持续性动词来替换，例如： He has been in the army/a soldier for htree years.（他参军已有3年了。）不能用has joined She has been up for quite some time.（她起床已有好久了。）不能用has got up Has your brother been away from home for a long time?（你哥哥离家已有好久了吗？）不能用has left 初中课本中的常用瞬间动词相应持续性动词关系如下： 1、go——be away 2、come——be here 3、come back——be back 4、leave——be away（be not here） 5、buy——have 6、borrow——keep 7、die——be dead 8、begin——be on 9、finish——be over 10、open——be open 11、close——be closed 12、lose——be lost 13、get to know——know 14、turn on——be on 15、get up——be up 16、sit down——sit/be seated 17、join——be in（…）或be a…member 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
（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.(现在我没有钱花了.) Jane has laid the table.(现在桌子已经摆好了.) Michael has been ill.(现在仍然很虚弱) He has returned from abroad. (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. ①for+时段为。。。。时间 ②since+过去一个时间点（译为：自从……以来） ③since+时段+ago ④since+从句（过去时） ●⑤It is+时段+since+从句（过去时） Mary has been ill for three days. I have lived here since 1998. ●注：瞬间动词（buy,die,join,lose……）不能直接与for since 连用。要改变动词 come/arrive/reach/get to-----be in go out----be out finish----be over open----be open die----be dead Buy---have Fall ill---be ill Come back---be back Put on ---be on/wear Worry---be worried Catch a cold---have a cold ……………… ★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.
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.
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

现在完成时中非延续性动词的转换 现在完成时是初中英语语法的重点之一。它表示过去发生的某一动作或存在的状态，一直持续到现在，并可以和以for或since引导的表示一段时间的状语连用，也可以用在以“how long”提问的句子中，句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, join, die, begin, 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。 同学们在使用这两类动词作谓语动词时，常会出现错误。例如： （误）Tom has bought the book for a week. （正）Tom has had the book for a week. （误）My father had joined the Party for ten years. （正）My father has been in the Party for ten years. 如果要表示动作的连续性，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： come/go/reach/arrive→be in/at, leave→be away from, borrow→keep, buy→have, join→be in/be a member of, die→be dead, start/begin→be on, finish/end→be over, open→be open (adj.), close→be closed (adj.), marry→be married 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 any new 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，since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。例如： He has been away from Beijing for two years. = He left Beijing two years ago. = It is two years since he left Beijing. = Two years has passed since he left Beijing. 练习：用现在完成时改写下列句子，使A，B两句意思基本一致。每空限填一词。 1. A. They came to our school in 1980. B. They ____ ____ ____ our school since 1980. 2. A. The man died five years ago. B. The man ____ ____ ____ for five years. 3. A. The meeting began two minutes ago. B. The meeting ____ ____ ____ for two minutes. 4. A. We borrowed two books last week.
