典型例题
1.现在完成时与一般过去时的区别.
[例1] －I have finished my homework.
－When you it？(天津市中考题)
A. have；finished B. do；finish；
C. did； finish； D. Will；finish
[例2] 一Tom out.
－Oh，has he？ What time he out？
A. is， did， go B. went， is， going
C. has gone， did， go D. is going， does， go
例1答案C，例2答案为C，例1中when强调具体的过去某一时间及当时的动作，所以用过去式；例2中“has”提示上文应用完成时态，“What time”暗示过去.
现在完成时和一般过去时的动作都发生在过去，但现在完成时表示过去发生的某一动作对现在造成的影响或结果，强调的是现在的情况，所以它不能和表示过去的时间状语连用，如：yesterday, last night, three weeks ago, in 1995等.而一般过去时只表示过去的动作或状态，和现在不发生关系，它可以和表示过去的时间状语连用.例如：
I have cleaned the hou.(我清扫了房间)(用的是现在完成时，它表明了房间现在是干净的)
I cleaned the hou an hour ago.(我一小时前打扫了房间)(用的是一般过去时，它强调的是动作“打扫”及其发生的时间)
日常生活中的对话表达如下意义通常用现在完成时：在没有明确的过去时间状语或上下文暗示过去时间的前提下，陈述完成了(发生了)某事或没有完成(发生)某事，或询问完成了(发生了)某事吗等.例如：黑神锅传奇
a.－Have you had your lunch？你吃过午饭了吗？－Yes，I have.吃过了.
一Where did you have it？在哪儿吃的？－I had it at home.在家里吃的.
