動詞按其動作發(fā)生的方式、發(fā)生過程的長短可分為延續(xù)性動詞與非延續(xù)性動詞.
一.延續(xù)性動詞表示能夠延續(xù)的動作,如：learn,work,stand,lie,know,walk,keep,have,wait,watch,sing,read,sleep,live,stay等.延續(xù)性動詞可以與表示時間段的狀語連用.
表示時間段的短語有:for+一段時間,for 2 years; since從句,since he came here; since+時間點名詞,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.非延續(xù)性動詞也稱終止性動詞、瞬間動詞,表示不能延續(xù)的動作,這種動作發(fā)生后立即結(jié)束.如:open,die,close,begin,finish,come,go,move,borrow,lend,buy等.
非延續(xù)性動詞在肯定句中與表示時間點的狀語連用,如：two years ago; at 5 o'clock;
例:He died 5 years ago.
否定的終止性動詞可以與表示時間段的時間狀語連用.例:I haven't left here for 3 years.I haven't heard from him for 3 weeks.
三.延續(xù)性動詞與非延續(xù)性動詞之間的轉(zhuǎn)換：leave --- be away,borrow --- keep,buy --- have,begin/start --- be on,die --- be dead,finish --- be over,join --- be in+組織機構(gòu),be a member of+組織機構(gòu),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.
