延续性动词与非延续性动词及其转换 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
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
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; 否定的终止性动词可以与表示时间段的时间状语连用
