Can you know their similarities and differences (相同点和不同点)? must和have to的用法 （1）must是情态动词，意为“必须”，侧重于说话者的主观看法，认为有必要去做某事。must没有人称、时态和数的变化。must的否定式mustn’t意为“不准，禁止”。例如： You must go to the hospital today. 今天你必须去医院。 Look at the sign. You mustn’t smoke here. 看这个标志，这里禁止吸烟。 15 （2）have to意为“必须，不得不”，后接动词原形，表示客观上的必须。have to的否定式don’t have to意为“不必，不需要”，相当于needn’t。例如： The last bus has gone. We’ll have to walk home. 最后一班车已经开走了。我们不得不走路回家。 We don’t have to get up early tomorrow morning. 明天早上我们不必早起。 16 【拓展】回答以must引导的一般疑问句时，若是否定答复，不可以用mustn’t，而需要用needn’t或don’t have to。例如： —Must I water the flowers? 我今天必须给花儿浇水吗？ —Yes, you must./ No, you needn’t. 是的，你必须。/不，你不必。 Tip: Have to has different forms. has to had to will have to have/has got to Tip: must not=mustn't do not have to=don't have to 17 B1 Millie is watching a video about school library rules on the school website.
