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.
2.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.
瞬间动词，也叫终止性、结束性动词。表示动作的结果，或表示短暂性、一次性的动作。
高一教材如：clo, leave, buy, join, become, begin, fall(掉下)，fall ill(病倒)，get to(know), come, go, e, hear, hear from, catch a cold等。
这类动词可以用于完成时，但在一般情况下，不能加上表示一段时间的状语或疑问词，但是在否定句中，瞬间动词也可以和表示一段时间的状语、连词连用，它的含义是好长时间没进行这个动作了，没进行此动作的状态就可以延续。
注意：终止性动词若需要表示一段时间，英语中须用替换词来替换该类动词。如：北京会计学习班
