中考辅导：英语延续动词与非延续动词的转换

　　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: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。

　　例: He has lived here for 6 years.

　　You can keep the book for 5 days.

　　I stayed there for 2 weeks last year.

　　How long did you stay there last year?

　　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.

　　否定的终止性动词可以与表示时间段的时间状语连用。例:

　　I haven‘t left here for 3 years.

　　I haven‘t heard from him for 3 weeks.examda
