名师点拨
英语中，动词按其动作发生的方式和过程的长短，可分为延续性动词和终止性动词。
1
延续性动词与终止性动词
1.延续性动词与终止性动词的概念和用法
要点 延续性动词 终止性动词
概念 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 终止性动词也称非延续性动词、瞬间性动词或短暂性动词，表示不能延续的动作，这种动作发生后立即结束
标志词 learn， work， lie， know， walk, keep, have， wait， watch， sing， read， sleep等 open, close, finish, begin, come， go， arrive, reach, get to, leave， move, borrow, buy等
要点 延续性动词 终止性动词
用法 延续性动词可以用于现在完成时，可与表示“时间段”的状语连用。如: I have learned English since I came here．我自从来到这儿就开始学英语了。 终止性动词可用来表示某一动作的完成，因此可用于现在完成时。如:
The train has arrived.火车已经到了。
续 表
要点 延续性动词 终止性动词
用法 延续性动词不能与表示短暂时间的“时间点”状语连用。如果要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。如： I got to know Jack two years ago.我是两年前认识杰克的。 终止性动词在现在完成时的肯定句中不可与表示“时间段”的状语连用；但在现在完成时的否定句中，可与表示一段时间的状语连用。如：
He has left here since 1986.（误）
He hasn't left here since 1986.（正）
【注意】常见的“时间段”状语有for短语和since短语等，如：for two years,since last year，during the past three years，how long
续 表
2.终止性动词如何与表示“时间段”的状语连用？
终止性动词不能与表示“时间段”的状语连用，如：He has died for three years.（误）。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：He has been dead for three years.
终止性动词或词组 延续性动词或词组
leave be away
borrow keep
buy have
begin / start be on
die be dead
终止性动词或词组 延续性动词或词组
finish be over
join be in / be a member of
open / close be open / closed
fall ill be ill
become be
catch a cold have a cold
arrive in(at) / reach / get to be in / at
续 表
（2）将句中表示“时间段”的状语改为表示过去的时间状语。如：He died three years ago.
（3）用句型“It is+时间段+since …”表达原意。如：lt is three years since he died.
（4）用句型“时间段+ has passed+since …”表达原意。如：Three years has passed since he died.
【拓展】
（1）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。
（2）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表示的时间既可以是“时间点”(从句谓语动词用终止性动词)，又可以是“时间段”(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，从句的谓语动词必须用延续性动词。如:
When we reached London, it was twelve o'clock.我们到达伦敦时，时间是12点。(reach为终止性动词)
Please look after my daughter while / when I am away.我不在时，请照看我的女儿。(be away为表示延续性的短语)
