“haveto”的否定形式怎么变成疑问句？

Answer 1

“have　to”的否定形式变成疑问句否定形式方法如下：

1. 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.

2. 特殊疑问句就是：what do you have to do?where do you have to go?否定形式：加助动词 don't have to（主语为第三人称单数要变成doesn't have to）疑问句形式：Do.. have to（主语为第三人称单数要变成Does..have to)

3. 只有don't have to他们的区别就是一个是错的一个是对的。否定形式：加助动词 don't have to（主语为第三人称单数要变成doesn't have to）疑问句形式：Do..have to（主语为第三人称单数要变成Does..have to）
