1) 两词都是'必须'的意思,have to 表示客观的需要, must 表示说话人主观上的看法,既主观上的必要。
My brother was very ill, so I had to call the doctor in the middle of the night. 我弟弟病得很厉害,我只得半夜里把医生请来。(客观上需要做这件事)
He said that they must work hard. 他说他们必须努力工作。(主观上要做这件事)
2) have to有人称、数、时态的变化,而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。
He had to look after his sister yesterday.
3) 在否定结构中: don't have to 表示"不必"
mustn't 表示"禁止",
You don't have to tell him about it. 你不一定要把此事告诉他。
You mustn't tell him about it. 你一定不要把这件事告诉他。 have to 是不得不,客观决定
must 是必须,主管要求 have to是指自己被迫做某事。比如我必须先写作业:I have to do my homework first.
must是指客观上的事实。比如这本书是他的:This book must be her's

have to 有客观造成不得不去做的事情。
must 有事物本身的条件要求必须如何去做。

HAVE TO 一般是别人有建议的语气,但是只得这一个方法或者一条路,只是你自己愿不愿意去做,这个方法里,你有得做与不做的选择。MUST一般意指必须去做,带有些许命令的口气。
