【语法感悟】
1. 现在完成时与一般过去时用法异同
1)相同点：
两个时态都表示一个在过去完成的动作。
2)不同点：
现在完成时强调的是与现在的关系，对现在产生的结果或影响等，属于现在时范围，谈论的是现在的情况；
一般过去时只表示动作在过去某一时刻发生，不表示和现在的关系，现在情况可能已发生变化。
e.g.: Who opened the door
谁开的门？(只强调过去开门这一动作，门现在可能已关上。)
Who has opened the door
谁把门开了？(强调门现在依然还开着。)
2. 结构上的区别
时态 结构
一般过去时 主语+ was/ were+其他 主语+ 动词过去式+其他
现在完成时 主语+has/ have +动词过去分词
时间状语的区别
时态 时间状语
一般过去时 yesterday, the other day (= a few days ago), last…, … ago, the day before yesterday, just now, in +过去时间（时间状语都很具体）
现在完成时 already, ever, just, recently, (not) yet, so far (迄今为止), up to now, till now, since, never, before（时间状语都很抽象）
4. 特殊情况
1. 现在完成时强调的是过去发生的动作对现在的影响，所以若是过去发生的一个动作，现在情况已经发生的变化，则不用现在完成时，而用一般过去时。
e.g.: I put my ruler in my pencil-box, but I can’t find it now.
若用I have put my ruler in my pencil-box, 则过去的动作put对现在的影响是“尺子还在笔袋里”，但实际上我现在找不到了，说明现在情况发生了变化，不用现在完成时。
【例题讲解】
My father (work) in a factory for five years. But now he is a teacher.
2. 现在完成时不与when引导的特殊疑问句连用, when后只用一般过去时表示已发生的动作。但现在完成时可与where, why等疑问词连用。
e.g.: ----The train has left.
----When did the train leave
e.g.: Where have you been
When _____you _______ your dictionary
A. did; lose B. has; lost C. will; lose D. does; lose
首先C.和D肯定不正确，不可能预测以后的事，也不可能总是丢东西；在A和B中，主要是询问这个动作什么时候发生的，而没有涉及与现在的联系。
