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: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
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:study, learn,work, stand,lie,know, walk, keep, have,wait, watch, sing,read, sleep,li ve,stay等。延续性动词可以与表示时间段的状语连用。延续性动词的用法很广,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。 表示时间段的短语有: 1.for+一段时间, eg: for2 years; for a longtime等 2.since从句,sincehe came here; 3.since+时间点名词+ago, eg:since last year, since 5daysago; 4.howlong; 二.非延续性动词也称终止性动词、瞬间动词或点动词,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, move, happen,marry,arrive/rea ch, post,fall, break, lose,give, join, receive,hear,he
间的的状语连用。 这类动词不是不能用于完成时态。只是不能用于由how long提问的句子和含有for+一段时间的完成时态中。 常见的这类动词有:go, come,leave,arrive,lose, land, catch,j oin, kill,find等。 例如:1. Hehasjoined the clubforalong time.( 错) 2.Hehasbeenamemberof theclub fora long time.(对) 3.His grandfather has died for over30 years. ( 错) 4. Hisgrandfather has been dead for over 30 years. (对) 【注意】 之所以将这些动词称为瞬间动词,是因为这些动词在眨眼之间发生并终结。故不能与表达“段”的长时间状语连用,不论是在进行时还是现在完成时中。 下面的例句是正确的: 1. He isdying.

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 不能与时间段连用。如:open, die, close, begin, finish, e, go, move, borrow, lend, buy等。 如果要与时间段连用,就把它转为延续性动词使用。 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. 但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---be open, close--- be closed fall ill --- be ill, get up---be up, catch a cold --- have a cold, e here --- be here, go there --- be there, be e --- be, e back --- be back, fall asleep --- be asleep, get to/ arrive/reach --- be (in), leave --- be away, go (get) out →be out,put on→wear get married ---- be married 等。 例:The old man died 4 years ago. ----The old man has been dead for 4 years.

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
when和while引导的时间状语从句与这一时态连用。所以区别when和while的用法成了这一单元的难点。(一)、when,while都有“当……时候”的意思。when既可表示某一点时间,也可以表示某一段时间。在when引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的,可与主句中的谓语动词同时发生,也可在其后发生。例如: 1、I was just reading a book when she came into my room. 她走进我房间时,我正在看书。 2、Were you writing when the teacher came in? 老师进来的时候,你在写信吗? 3、When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。(二)、while只能表示某一段时间,不能表示某一点时间。在while引导的时间状语从句中,其谓语动词只能是延续性的,而且也只能与主句中的谓语动词同时发生或存在。例如:1、While Jim was mending his bike, Lin Tao came to see him. 正当吉姆修自行车时,林涛来看他。 2、You can’t do your homework while you’re watching TV. 你不能一边看电视一边做家庭作业。(三)、另外,when和while的区别还在于:while引导的时间状语从句多用进行时态,而when引导的时间状语从句多用一般时态。例如: 1、While they were talking , the bell rang. 正在他们谈话的时候,上课铃响了。 2、I was doing my homework when my mother came back home yesterday evening. 昨天晚上妈妈回家的时候 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.
(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.

Work out the rule(s):
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.

延续性动词与非延续性动词 试比较,判断下列句子的正误。 翻译:我离开这所学校已八年啦。 【误】I have left this school for eight years. 【正】I have been away from this school for eight years. 解析:当现在完成时与表示一段时间的时间状语连用时,谓语动词必须使用延续性动词。如果谓语动词是非延续性动词则需要转化为对应的延续性动词。 延续性动词表示能够延续的动作,也可 以表示经验与经历,如: learn; sleep; keep; live等 可以与for 和 since 引导的 时间状语连用 He has lived here for 6 years. 非延续性动词也叫短暂性动词,表示不能 延续的动作,这种动作发生 后立即结束,如:open; begin; finish; come; go; borrow等 不能与for 和 since 引导的 时间状语连用 She has already finished her work. 1. 转化为相应的延续性动词 borrow → keep buy → have put on → wear 2. 转化为be+形容词/副词/介词/名词 begin/start → be on go out → be out die → be dead open → be open get to/ arrive in/reach → be in+地点come/ go → be + 相应的介词短语 finish → be over fall ill → be ill get up → be up fall asleep → be asleep join → be in+活动/组织go to school → be in school become → be make friends → be friends close → be closed go to bed → be in bed leave → be away(from)

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.
延续性与非延续性动词在现在完成时态中的使用 ☆有一些动词是瞬间动词,也叫非延续性动词,这些动词一发生就结束了,常见的有:come, go, arrive, reach, leave,begin, start, buy, join, die, borrow, get up, become, open, stop等。这些动词虽然可以用于现在完成时(说明某个动作的结果还存在),但由于它们不能延续,因此不能跟表示一段的时间状语连用。 e.g. Jim has come back. (正) Jim has come back for a month. (误) come back的动作不能延续一个月,因此错误。 ☆瞬间动词不可以用于有段时间的现在完成时态中,因此,若要解决这一问题,就应把它改为相应的延续性动词或短语,主要有以下几种: ①用相应的延续性动词 如:buy →have borrow →keep come/go/become →be put on →wear catch a cold →have a cold ②转换成be+名词 如:join →be a member of go to school →be a student ③转换成be+形容词或副词 如: die →be dead leave →be away begin →be on finish →be over fall asleep —be asleep open →be open get up →be up close →be closed ④转换成be+介词短语 如: come to/go to/arrive in (at)/get to/reach …→be in/at… join the army →be in the army(军队) e.g. I have borrowed the book. I have kept the book for two days. Jim has joined the band. Jim has been a member of the band for a month. His grandfather has died. His grandfather has been dead for 2 years. My father has arrived in China. My father has been in China for a week. ☆在否定句中,非延续性动词也可以与时间段连用。 e.g. I haven’t borrowed books from the library since last year. 自去年以来我就没有在图书馆借过书。 Jim hasn’t come back for a year. 吉姆已有一年没回来了。 ☆现在完成时的几种常见的句型转换。 现在完成时可以转化成一般过去时,还可以转化成“It is/has been +时间段+since从句(用一般过去时)”等句型。 e.g. Jim has been back for a month. = Jim came back a month ago. = It is/has been a month since Jim came back. = A month has passed since Jim came back. I have kept the book for two days. = I borrowed the book two days ago. = It is / has been two days since I borrowed the book. = Two days has passed since I borrowed the book.
