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.has B.had C.is it since D.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.

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：
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。如：Brown has taken a slight cold. 注意下列句子： I have caught 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。如：be,drink,fly,eat,keep,lie,live,rain等。 延续性动词常不能和表示一个短暂具体的时间状语连用；这类动词如用于进行时态，则可以和表示一个短暂具体的时刻连用。 He worked at eight yesterday afternoon.(×) 3、代替终止性动词的方法 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
中考英语短暂性动词与延续性动词相互转换讲练 中考英语短暂性动词与延续性动词相互转换对应表 语法讲解： 1.现在完成时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。例： He has been away from Beijing for two years. = He left Beijing two years ago. When did the train arrive here? B. How long ____ the train ____ here? 2.在现在完成时的肯定句中，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。但可以用其他句式来表示同一个意思。例： Lucy has come back. The old man died 4 years ago. = The old man has been dead for 4 years.
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. 3.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 h asn’t bought any new clothes since last year. I haven’t borrowed the book for a long time. 巩固习题： 1. When he arrived at the bus stop, the bus ________ for 20 minutes. A. has left B. had left C. has been away D. had been away 2.

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
延续性动词和短暂性动词的区别 1 延续性动词：表示可以延续一段时间的动作或状态。 延续性动词常不能和表示一个短暂具体的时间状语连用。live,run,stay,clean,play,hold,watch,teach,read,study,teach,eat,drink,write,dance, sing,smoke 2短暂性动词：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,finish,go,leave,lend,mary,reach,receive,ope n,sell,start,stop 等。 3、代替短暂性动词的方法 a)用延续性动词代替短暂性动词 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”代短暂性动词 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”代短暂性动词 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 d)用“be＋介词短语”代短暂性动词 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 （此文档部分内容来源于网络，如有侵权请告知删除，文档可自行编辑修改内容，
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。如： The train has arrived.火车到了。 Have you joined the computer group你加入电脑小组了吗 2.终止性动词表示的动作极其短暂，不能持续。因此，不可与表示一段时间的状语连用(只限肯定式)。如： (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.

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)
延续性动词和非延续性动词的用法 1、现在完成时表示动作从过去某个时候开始一直持续到现在，而与一段时间连用时应注意 句中的谓语动词必须是延续性动词，非延续性动词不可以和一段时间连用。 我离开家乡我离开家乡已有10 年了 误： I have left my hometown for 10 years. 正： I have been away from my hometown for 10 years. 我买这本书已有两天了。 误： I have bought this book for two days. 正： I have had this book for two days. 2、在否定句中，非延续性动词可与一段时间连用。 I haven’ t gone to see him for several months. 我已经好几个月没去看他了。 3、在肯定句中非延续性动词与表时间段的状语连用时可采用下述三种方法： a．将非延续性动词转化为延续性动词 非延续性动词延续性动词非延续性动词延续性动词 buy have borrow keep open be open close be closed begin/start be on come be here go be there finish be over die be dead catch a cold have a cold put on wear get up be up wake up be awake fall asleep be asleep lose not have join be in leave be away arrive/reach be b．将时间状语改为过去时间，且用一般过去时代替现在完成时。 c．用句型“It ’ s时+间段 + since 从句（从句的非谓语动词用非延续性动词的过去式）”表示。 It is two years since the old man died. 这个老人已经去世两年了。
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"
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
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. has B. had C. is it since D. 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 →kee p 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？
