现在完成时中短暂性动词变延续性动词归纳表

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: ⑴for+一段时间, 如：for 2 years; ⑵since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,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.

三.延续性动词与非延续性动词之间的转换：（考试重点）

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，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。
