延续性动词与非延续性动词

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非延续性动词。1.

延续性动词与非延续性动词的概念和用法要点延续性动词非延续性动词概

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非延续性动词也称终止性动词、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要点延续性动词非延续性动词标志词learn,work,lie,know,walk,keep,have,wait,watch,sing,read,sleep等open,close,finish,begin,come,go,arrive,reach,getto,leave,move,borrow,buy等要点延续性动词非延续性动词用

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。非连续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。要点延续性动词非延续性动词用

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等非延续性动词。如:非延续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:Hehasleftheresince1986.(误)Hehasn’tleftheresince1986.(正)要点延续性动词非延续性动词用

点延续性动词非延续性动词用

法I

years

ago.我是两年前认识杰克的。Hehasn’tleftheresince1986.(正)【注意】常见的表示“时间段”的状语有for短语和since短语等,如:fortwoyears,sincelastyear,duringthepastthreeyears2.

非延续性动词如何与表示“时间段”的状语连用?非延续性动词不能与表示“时间段”的状语连用,如:Hehasdiedforthreeyears.(误)。那么,应如何正确表达呢?可以采用下面的4种方法:(1)将句中非延续性动词转换为相应的延续性动词。如:Hehasbeendeadforthreeyears.非延续性动词或词组延续性动词或词组leavebeawayborrowkeepbuyhavebegin/startbeondiebedeadfinishbeover非延续性动词或词组延续性动词或词组joinbein/beamemberofopen/closebeopen/closedfallillbeillbecomebecatchacoldhaveacold非延续性动词或词组延续性动词或词组arrivein(at)/reach/gettobein/at(2)将句中表示“时间段”的状语改为表示过去的时间状语。如:Hediedthreeyearsago.(3)用句型“Itis＋时间段＋since…”表达原意。如:ltisthreeyearssincehedied.(4)用句型“时间段＋haspassed＋since…”表达原意。如:Threeyearshaspassedsincehedied.【拓展】(1)非延续性动词的否定式与until/till连用,构成“not＋非延续性动词＋until/till…”的用法,意为“直到……才……”。如:You

can’t

leave

here

until

I

arrive.

我到了,你才能离开这里。(2)非延续性动词可以用于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”(从句谓语动词用非延续性动词),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为非延续性动词)Please

look

after

my

daughter

while

/

when

I

am

away.我不在时,请照看我的女儿。(beaway为表示延续性的短语)
