回答（1）：

否定形式：don't/ doesn't/ didn't have to 没必要
提问的话，一般疑问句就是 Do you have to wear sports shoes?
肯定回答是：Yes，we do. 否定回答是：No, we don't.
特殊疑问句就是：what do you have to do?where do you have to go?当然这个要看具体情况来问，没有专门针对have to的疑问词。

回答（2）：

have to 改成否定句要看前面的事态和人称，否定形式改成，don't have to ，does't have to，did‘t have to 。
疑问句同理，以助动词提问比如，Do i have to.... ?Does she have to...?
