Practice:
--Do you have to...in the school
--Yes, we do. We have to....
--No, we don't. We don't have to...
clean the classroom every day
do morning exercises every day
listen to the teachers in class
have classes every day
have to与must
have to着重于客观的需要，含有“不得不”的客观强制性；must着重于主观上自己认为有义务、有必要。
如：
She has to clean the room every week.
她每周都得打扫房间。
I must go now.
Language point:
含有have to的句子变一般疑问句或否定句时要借助助动词do / don’t或does / doesn’t；而含有must的句子变一般疑问句是直接将must提前至句首，变否定句是在must后加not。如：
He doesn’t have to do it. 他不必做那件事。
He mustn’t do it. 他不许做那件事。
Does he have to do it
他不得不做那件事吗？
Must he do his homework
他必须做他的作业吗？
在否定句中，don’t / doesn’t have to表示“没有必要”，must not / mustn’t表示“不允许”。如：
You don’t have to go there.
你不必去那儿。
You must not / mustn’t go there.
你不许去那儿。
