文档介绍：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, Sta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：⑴for+一段时间，女口 ： for 2 years;⑵SinCe从句，女口 SinCe he Came here; since+过去时间点名词，女口 SinCe last year SinCe 5 days ：
He has lived here for 6 years. You Can keep the book for 5 days.
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.
：
伊|| : He left five minutes ago. = He has been away for five 是指他离开的动作是5分钟之前发生的，是过去时。也就是说从他离开到现在已经有 五分钟了，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。下面是一些短暂性动词及相应的延续性动词，须牢记。
