浅谈延续性动词和终止性动词

发布时间:2016-02-29  编辑:查字典英语网小编

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.

  (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。下面列举几例:leavebe away, borrowkeep, buyhave, begin/startbe on, diebe dead, move tolive in, finishbe over, joinbe in/be a member of, open sth.keep sth. open, fall illbe ill, get upbe up, catch a coldhave a cold。

  (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。

  

3.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:

  He hasn't left here since 1986.

  I haven't heard from my father for two weeks.

  

4.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,意为直到才。如:

  You can't leave here until I arrive.直到我到了,你才能离开这里。

  I will not go to bed until I finish drawing the picture tonight.今天晚上直到我画完画,我才上床睡觉。

  

5.终止性动词可以用于when引导的时间状语从句中,但不可以用于while引导的时间状语从句中。when表示的时间是点时间(从句谓语动词用终止性动词),也可以是段时间(从句谓语动词用延续性动词)。而while表示的是一个较长的时间或过程,从句谓语动词用延续性动词。如:

  When we reached London, it was twelve o'clock. (reach为终止性动词)

  Please look after my daughter while/when we are away. (be away为延续性动词短语)

  

6.终止性动词完成时不可与how long连用(只限于肯定式)。如:

  误:How long have you come here?

  正:How long have you been here?

  正:When did you come here?
