一般过去时VS现在完成时区分讲解和练习（含答案） 时态 用法 谓语V.形式 常用时间状语 一般过去时 过去某个时间发生的动作或存在的状态 was/were/did ...ago, last..., just now in +过去的时间点 表示过去经常或反复发生的 现在完成时 表示过去发生的动作或存在的状态对现在仍有影响 have/has been have/has done already、since、for just、yet、ever... 表示从过去某时间一直持续到现在的动作或状态，常与for/since引导的状语连用 【现在完成时与一般过去时的区别】 现在完成时强调已经完成的动作对现在造成的影响或结果，而一般过去时则只表示过去发生的动作或存在的状态，和现在没有关系，所以，表示过去的时间状语只能与一般过去时连用，而不能与现在完成时连用。如： Jack heard about the news yesterday.
