1、一、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,如：for 2 years，for a long time;since从句,如：since he came here;since+时间点名词,如：since last year,since 5 days ago;how long等。第1页/共18页二.非延续性动词也称终止性动词、瞬间动词或点动词,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(start),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

2、，如：twoyearsago;at5oclock;eg：Hedied5yearsago.第2页/共18页终止性动词所表示的动作极其短暂且不能持续，所以在完成时的肯定句中不能和表示一段时间的状语连用。如：for3years，sincehecamehere，howlong，ect.且看下面三个错误句子：1)Jimhascomehereforfiveyears.2)Hehasdiedfor3years.否定的终止性动词可以与表示时间段的时间状语连用。第3页/共18页现在完成时中延续性动词和非延续性动词 延续性动词：study learn sleep live sing dance swim drin
