瞬间动词到延续性动词的转化

1、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+ 段时间，for 2 years; si nee 从句,si nee he came here; si nce+时间点名 词,since last year, since 5 days ago; how long; for a long

2、 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 yea

3、rs ago; at 5 oclock;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 havent left here for 3 years. Ihavent heard from him for 3 weeks.中学阶段常用延续性动词与非延续性动词之间的转换如下：Come t be hereGo t be there leaver be away, borrow t keep, buy t have, begin/start t be on, die t be dead, move toT live in, finish t be ov
