16、经开始，持续到现在的动作或状态。v 基本结构：主语+have/has+过去分词v 否定形式：主语+have/has+not+过去分词v 常用的时间状语：already,yet,just,since,recently,in the past few years等等24使用现在完成时应注意：v have/has gone to 与 have/has been to 的区别：have/has gone to 强调“去而未归”；have/has been to 强调“去而归还”。have/has been to常和once,scince,never,ever连用；have/has gone to则不可

18、可以用来表示过去的一个时间到现在这段时间内重复发生的动作。例如：We have had four texts this semester.You have said that twice.26举例v 句子中谓语动词是用一般过去时还是用现在完成时，取决于动作是否对现在有影响。v 句子中如有过去时的时间副词（如yesterday,last week,in 1960）时，不能使用现在完成时，要用过去时。错误27比较练习v 1.-Where _you _(put)the book?I cant see it anywhere.-I _(put)it right here.But now its gon
