1、精选优质文档-倾情为你奉上短暂性动词，延续性动词和现在完成时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。如：live,work, study, learn, sleep等，延续性动词可以和表示一段的时间状语连用。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。这类动词有：go,come, arrive, leave, begin, start, join, marry等；在否定句中，短暂性动词可以和表示一段时间的状语连用。We havent heard from Jane for a long time.短暂性动词的肯定式不能与表示一段时间的for或since或

2、how long等状语连用。值得注意的是，表示一段时间的状语除了“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。例如：.I have received his letter for three days（） I have received his letter.（）How long did she leave .（） How long has she been away?

5、nce I received his letter. His father died three years ago.看一个句子可以用以下几种说法：他离开上海已经3天了。He left Shanghai three days ago. He has been away from Shanghai for three days/since three days agoIt is/has been three days since he left Shanghai.Three days has passed since he left Shanghai.几点注意事项:（1）have been(to

6、)与have gone( to)的区别：have been(to)表示“去过某地（现在已经回来了）”，可用于各人称；have gone(to)表示“去某地了（说话时某人不在当地）”，可能在去的路上，可能已在某地，也可能在回来的路上，总之，人不在这里。常用第三人称作主语。前者可与once,never, several times等连用，后者则不能。如：They have been to Beijing twice.他们去过北京两次。He has gone to Beijing他去北京了。注意比较 has gone to, has been to, has been in的意义：He has go

7、ne to Amercia.（他到美国去了。他不在这里）He has been to Amercia.（他去过美国。现已回来）He has been in Shanghai.（他在上海呆过。现在不在上海）He has been in shanghai for years.（他在上海多年。现在还在上海）（2）终止性动词现在完成时的否定式，已变成一种可以延续的状态，因此可以和表示一段时间的状语连用。如：I haven t left here since 1997.自从1997年以来，我一直没有离开过这儿。另外，动词的延续性与非延续性还体现在这两种句型中：延续性动词的肯定式+till/until 短
