动词按其动作发生的方式、动作发生过程的长短，可分为延续性动词和非延续性动词。
一、延续性动词
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。 延续性动词的用法很广，但常见于现在完成时中的句子中，且常与for，how long，since等引导的表示一段时间短语（时间状语）或句子（状语从句）连用。例如：表示时间段的短语有:for+ 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:I have lived here for 23 years. You can keep the book for 5 days. How long did you stay there last year? I stayed there for 2 weeks last year.
二、非延续性动词
非延续性动词也称终止性动词、瞬间动词或短暂性动词，表示不能延续的动作，这种动作发生后立即结束。如die、borrow、 begin、 buy、join、reach, come、 go、open、close, become、leave等。 可用于现在完成时态,但由于动作是瞬时间完成的所以不能与for或since引出的时间状语连用，又叫点动词。英语中常见的非延续性动词在完成时态中可改为相应的表示延续性的动词或短语,这时可与表示一段时间的的状语连用.
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.
非延续性动词在否定句中可以与表示时间段的时间状语连用。例:I haven't left here for 23 years. I haven't heard from him for 3 weeks.
