初中英语

I don't have......不是现在完成时
现在完成是应该是I haven't done
它是一般现在时,就表示我没有......

Do you have a bike?
I don't have a bike.

Do you have it?
I don't have that.

have同样可以作为行为动词，解释为有
而在现在完成时中have是以助动词的形式出现，其并无实际意义，因此我们在表示没有的时候同样可以说
I have't

Have you....?
Do you have....?
I haven't
I don't have

Do you have ...?
I have no .....
