延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。延续性动词的用法特征1.延续性动词可以用于现在完成时，其完成时态可与表示"段时间"的状语连用。表示"段时间"的短语有：for two years, during the past three years, since last year, how long等。如：I have learned English since I came here.自从我来到这儿就学英语了。延续性动词不能与表示短暂时间的"点时间"状语连用。如：It rained at eight yesterday morning.(误) rain为延续性动词，而at eight表示"点时间"，前后显然矛盾。如果用延续性动词表示一瞬间的动作，可以借助come, begin, get等终止性动词来表示。上句可改为：It began to rain at eight yesterday morning.(正)又如：-When did you get to know Jack?-Two years ago.-Then you've known each other for more than two years.-That's right. 非延续性动词 这类动词表示的动作不能延续，即动作发生后立即结束。 take 属于持续性动词get 属于非持续性动词.

（1）延续性动词表示动作是可持续的，如live, stay, study, work, keep, teach等可以和表示一段时间的状语连用。（2）非延续性动词表示瞬间动作，动作一经发生便立即结束，如buy, lend, borrow, stop, finish, arrive, join, go, come, catch等，非延续性动词不能与表示一段时间的状语连用。如果和表示一段时间的状语连用，就要用其他词代替。（不懂就追问我吧，很高兴能为你解答。）
