A:I have finished my homework
B:when did you finish it
上面A的用现在完成时,为什么下面B用一般过去式呢?而不是现在完成时呢?

完成时态不能跟具体时间,而他问得是你什么时候完成的,要用具体时间回答所以要用过去时.第一个是我已经完成它了,对于第二问有影响也就事对现在有影响所以要用完成时.

A:I have finished my homework I have finished my homework I have finished my homework.反义疑问句 ---I have finished my homework already, mum. I have finished my homework now. I (have finished) my homework now.选择题一、 My mother said ( ) i finished my homework,i can have a re I have finished my homework.可否这么说 I finished my homework.为什么 "I have finished my homework."和“I finished my homework."有区别吗（1）介绍：a.I have already finished my homework.Have you found I have finished my homework before I leave home. I have finished my homework before I ______(leave).
