i didn't 和i haven't 老搞不清该怎么用
我昨天没有接（机）到他们,这句是该用didn't 还是haven't?
请解释一下为什么要这么用?

didn't是过去时 haven't是过去完成时
didn't表示过去没有
haven't表示过去到现在一直没有
这边用didn't就可以了
如果是我作业还没完成就用havn't
I haven't finished the homework.

i didn't 和i haven't 老搞不清该怎么用 I haven't got还是I didn't have got 请问I didn't see him和I haven't see him的区别 I haven‘t do 和I didn’t do 的区别. if i didn't met you和if i haven't met you 的区别是? didn't haven't 一个英语的差异 I haven't visit here for a long time 和I didn't visit Sorry,I__you but I didn't __you. 该怎么填 I didn't do anything wrong.I haven't do anything wrong.I had haven't和 didn't的区别 "I didn't have" 和 "I didn't had" I don't have it和 I haven't it.
