haven✀t和don✀t have有什么区别

二者不同。haven't 中的have 是助动词,必须和动词一起使用，才能构成谓语。如：I haven't got a dress.
而， don't have中的have 是实义动词，可以单独使用构成谓语.如：I don't have a dress.
希望可以帮到你！

haven't和don't have区别:

• haven't否定两种句子:
  1.一般的'有和没有'的问句，这种情况它完全可以和don't have互换。
  Have you got a pen?
  No, I haven't.
  =No, I don't have one.
  Do you have a pen?
  No, I don't have one.
  =No, I haven't.
  
  2。现在完成时问句，此时，不可用don't have代替。
  Have you finished your homework?
  No, I haven't.
  =No, I haven't finished it yet.
  

前者have是助动词，后接动词的过去分词形式组成完成时；
后者have是实义动词，通常解释为“有”，后接宾语。

haven't用于完成时，eg，I haven‘t been to here。
don't have，是sb没有，用于一般现在时，eg。I don't have money。

haven＇t是have not而don＇t have是do not have所以区别就在这里
