瞬间动词又叫做结束性动词（是一个概念的不同叫法：
瞬间动词,也叫终止性、结束性动词.表示动作的结果,或表示短暂性、一次性的动作.如：close,leave,buy,join,become,begin,fall(掉下),fall ill(病倒),get to(know),come,go,see,hear,hear from,catch a cold等.这类动词可以用于完成时,但在一般情况下,不能加上表示一段时间的状语或疑问词,
但是在否定句中,瞬间动词也可以和表示一段时间的状语、连词连用,它的含义是好长时间没进行这个动作了,没进行此动作的状态就可以延续.如：
I haven't heard from my parents for a long time.我有好长时间没收到父母来信了.
He hasn't left home for a week.他有一个星期没出门了
浅谈终止性动词和延续性动词
延续性动词:live,run,stay,clean,play,hold,watch,teach,read,study,teach,eat,drink,write,dance,sing,smoke
瞬间性动词:
open,stop,like,love,die,win,close,shot,begin,start enter,finish
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,lend,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.
Put on your coat,or you′ll catch/take/get a cold.
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.(×)
I have had 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.(×)
He was working at eight yesterday afternoon.()
3、代替终止性动词的方法

3、用be替代become

5、be＋awake代wake/wake up 6、be＋gone代lose,die,sell,leave

9、be＋missing(gone,lost)代lose
c)用“be＋副词”代终止性动词

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
