动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词.
一.延续性动词表示能够延续的动作,如：learn,work,stand,lie,know,walk,keep,have,wait,watch,sing,read,sleep,live,stay等.延续性动词可以与表示时间段的状语连用.
表示时间段的短语有:for+一段时间,for 2 years; since从句,since he came here; since+时间点名词,since last year,since 5 days ago; how long; for a long time等.
例:He has lived here for 6 years.You can keep the book for 5 days.I stayed there for 2 weeks last year.How long did you stay there last year?
二.非延续性动词也称终止性动词、瞬间动词,表示不能延续的动作,这种动作发生后立即结束.如:open,die,close,begin,finish,come,go,move,borrow,lend,buy等.
非延续性动词在肯定句中与表示时间点的状语连用,如：two years ago; at 5 o'clock;
例:He died 5 years ago.
否定的终止性动词可以与表示时间段的时间状语连用.例:I haven't left here for 3 years.I haven't heard from him for 3 weeks.
三.延续性动词与非延续性动词之间的转换：leave --- be away,borrow --- keep,buy --- have,begin/start --- be on,die --- be dead,finish --- be over,join --- be in+组织机构,be a member of+组织机构,open sth --- keep sth open,fall ill --- be ill,get up---be up,catch a cold --- have a cold,come here --- be here,go there --- be there,become --- be,come back --- be back,fall asleep --- be asleep,get to/ arrive/reach --- be (in),leave --- be away from,get to know --- know,go (get) out →be out,put on→ wear；catch a cold →have a cold等.例:The old man died 4 years ago.----The old man has been dead for 4 years.---- It is 4 years since the old man died.----Four years has passed since the old man died.He joined the Party 2 years ago.-----He has been in the Party for 2 years.I bought the book 5 days ago.---- I have had the book for 5 days.
