must 表示因主观需要或责任感的驱使而有必要或义务去做某事，多译为“必须”。
have to 可用于不同的时态，有人称和数的变化，其一般现在时的第三人称单数形式为has to；过去式为had to。
must 一般只用来表示现在，没有人称和数的变化。
have to与must的不同点
have to have to的否定形式为don’t/doesn’t /didn’t have to，表示“不必”。
must must的否定形式为mustn’t，表示“禁止，不准”。
have to与must的不同点
He has to leave school because his family is poor.
因为家里穷，他不得不退学。(受客观因素影响)
We must do something about it.
关于这件事我们必须做点什么。(责任感的驱使)
【拓展延伸】以must开头的一般疑问句的肯定回答用must，否定回答用needn’t或don’t have to。

Don’t be noisy in the classroom. You can’t eat in the classroom, but you can eat in the dining hall. Don’t listen to music in the hallways. Don’t fight with others.
Our teachers are strict with us and the school rules are good for us. I think you will like our school. Hope to see you soon.
Yours,
Liu Yang
