18、an the classroom before going home.dont have to表示“不必，没有必要”，即客观上没有必要做某事。You dont have to come with me.辨析比较： have to / musthave to强调客观需要，must则强调主观看法；have to有时态、人称和数的变化，而must只有一种形式；二者的否定形式的意义不同：dont have to表示“不必”，相当于dont need to, neednt; mustnt则表示“不允许，禁止”；His mother was ill and he had to stay there to
