haveto的否定形式怎么变以及疑问句

如题所述

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。

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...?
