英语延续动词与非延续动词的转换

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.
