探究二. 延续性动词与非延续性动词

其动词必须为延续性动词，非延续性动词不能与表示一段时间的状语连用。
英语中，按动词延续的时间长短，可将动词分为____________和_____________。延续性动词，如：learn “学习”，wrk“工作”，play“玩耍”等。短暂性动词，即动作一开始便结束的动词，如：cme“来”，g“去”，begin“幵始”，becme“变成”，buy“购买”。延续性动词，就是可以想做多久就做多久的事情，只要你不累。短暂性动词就是一瞬间的事情。当句子中出现“fr+一段时间”，“since+从句”，“since+表示时间点的名词”，hw lng等，这些时间状语的时候，不能使用短暂性动词，要使用延续性动词。用于现在完成时。
（口诀记忆：看见since，fr，hw lng；廷续性动词不能忘）
