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。
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: 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, 表示不能延续的动作,: 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.
三。延续性动词与非延续性动词之间的转换:
例: He left five minutes ago. = He has been away for five minutes。
这句话的意思是指他离开的动作是5分钟之前发生的,,这个动作是延续的,要用现在完成时,并且要把原来的短暂性动词 改为延续性动词.
