延续性动词与非延续性动词及其转换
动词按其动作发生得方式、发生过程得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得动作,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得状语连用。
表示时间段得短语有: ⑴ for+一段时间, 如 :for 2 years; ⑵ since从句, 如 since he came here; since+过去时间点名词, 如 since last year, since 5 days ago、 例:
He has lived here for 6 years、 You can keep the book for 5 days、
二、 非延续性动词也称终止性动词、瞬间动词, 表示不能延续得动作,这种动作发生后立即结束。如: open, die, close, begin, finish, e, go, move, borrow, lend, buy等。
非延续性动词在肯定句中与表示时间点得状语连用,如:two years ago; at 5 o'clock;
例: He died 5 years ago、
三、延续性动词与非延续性动词之间得转换:
例: He left five minutes ago、 = He has been away for five minutes、
这句话得意思就是指她离开得动作就是5分钟之前发生得,就是过去时。也就就是说从她离开到现在已经有五分钟了,这个动作就是延续得,要用现在完成时,并且要把原来得短暂性动词 改为延续性动词。
下面就是一些短暂性动词及相应得延续性动词,须牢记。
