1、短暂性动词与延续性动词,一、定义：,短暂性动词是指动作一旦发生就立即结束。它不能和一段时间连用,延续性动词是指动作发生后还可以延续一段时间或者相当长的一段时间。,二、常见的短暂性动词有哪些呢？,go,come,arrive,leave,begin,start,join,marry 等,延续性动词呢？,live,work,study,learn,sleep等,注意：,短暂性动词的肯定式不能与表示一段时间的for或since或how long等状语连用。在否定句中，短暂性动词可以和表示一段时间的状语连用。：e.g;We havent heard from Jane for a long time.
2、,延续性动词可以和表示一段的时间状语连用。,表示一段时间的状语“for+一段时间”外，还有since+n./从句（时间点），since+时间段+ago，疑问词how long，in the past+时间段，all these+时间段，fromto（时间点）以及till/until+n./句子等等。,如果短暂性动词与表示一段时间的时间状语连用，必须将短暂性动词改为延续性动词。,现归纳总结一下由非延续性动词到延续性动词的转换,arrivebe in begin(start)be ondie be dead come backbe backleave be away(from)fall ill(s
