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。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+ 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,arrive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, 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,get married---be married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 Party for 2 years. I bought the book 5 days ago. ---- I have had the book for 5 days. 编辑本段动词相关分类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。 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,又叫非点动词。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。 二、非延续性动词可用与现在完成时态,但由于动作是瞬时间完成的所以不能与for或since引出的时间状语连用，又叫点动词.英语中常见的非延续性动词在完成时态中可改为相应的表示延续性的动词或短语,这时可与表示一段时间的的状语连用.

英语中延续动词有很多：延续动词指的是：动作能够持续发生一段时间的动词叫延续动词。例如：live study keep wait have be 等动词。不能持续一段时间的动词，称非延续动词。如：leave start join buy borrow die 等。while 与when 的区别：while 引导的从句必须是延续性动词，而when可以用延续性动词也可用非延续性动词。

常见到的瞬间动词及延续性动词的转化如下：start----be onjoin----be a member of / be indie----be deadbuy---haveborrow----keepend---be overleave----be away from when与while都引导时间状语从句，when后可以接瞬间动词或延续性动词，while后只可以接延续性动词。

动词有两种,点动词(终止性动词)和持续性动词.大部分动词都是持续性动词,只有少数是点动词,你把那几个点动词背背就成了. 一、持续性动词 持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 终止性动词又称为点动词,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 since或for引导的表示一段时间的状语连用.那么,上面两个句子应该怎样译成英语呢?请看下面四种译法： 1．把终止性动词改为延续性的动词.例如： ①The old man has been dead for a week． ②He has been here since three days ago． 2．把原句中的一段时间改为表示“过去”的时间,时态由现在完成时改变成一般过去时.例如： ①The old man died a week ago． ②He came here three days ago． 3．用“It is+时间+since…”句式.例如： ①It is／has been a week since the old man died． ②It has been／is three days since he came here． 4．用“多长时间+has passed+since…”句式.例如： ①A week has passed since the old men died． ②Three days had passed since he came here．
