19、e，have，keep，know，learn，lie，live，read，sing，sleep，stand，stay，wait，walk，watch等。延续性动词使用方法很广，但常见于现在完成时中句子中，且常与for，how，long，since等引导表示一段时间状语或状语从句连用。比如：1I have learned more than 1，000 Chinese words since I came to China 自从来到中国，我已经学会了l，000多个汉字。2We have lived in Linqing since we came here自从来到这儿，我们就一直住在临清。3I

21、某一动作完成。比如：They have reached Shanghai他们已经抵达了上海。Has he gone to London?他已经到伦敦去了吗?2.终止性动词表示动作极其短暂，不能连续，所以，在现在完成时中普通不能和以since，for等引导表示一段时间状语连用。比如：那老人已经死了一周了。The old man has died for a week(误)他三天前就已经来这儿了。He has come here since three days ago(误)在以上两句中，die和come都是终止性动词，可用于现在完成时，但不能与以 since或for引导表示一段时间状语连用。第2
