短暂性动词和延续性动词
可以从字面上理解，持续的动作就是延续动词，反之就是瞬间动词（短暂动词），这个有这种感觉还是很好理解的，你看看下面的词吧。

延续性动词: live,run,stay,clean,play,hold,wat ch,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
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,cl ose,come,fall,dic,finish,go,leave,
lend,mary,reach,receive,open,s ell,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。

.
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

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
