(过去时: 无论人称和单复数都用didnt have to) Eg:Nick doesnt have to wear a uniform. 尼克不必穿制服。 We didnt have to do our homework at once. 我们不必马上完成作业。 疑问句：Do 、Does或Did+主语+have to +动词原形+其他 Eg:-Do you have to stay at home on weekends? 周末你必须呆在家里吗 -Yes, I do. / No, I dont. 是的我必须。不我不必。 Did he have to go to bed by 11:00 last night? 昨晚他不得不11点前上床睡觉吗？【典型例题】Lucy has to wear sports shoes for gym class.(该为否定句)Lucy _ _ to wear sports shoes for gym class. 2.情态动词must的用法：must表示说话人的主观看法，及主观上的必要性，还用于命令或愿望。只用于现在时，无人称和单数的变化。在表示过去、将来和完成时，用have to的相应形式来代替must.在表示有做某一个动作的必要和义务，它的意思是“必须，应该”。Eg:You must finish your homework first.你必须先完成作业。表示有很大把握的判断或者推测，意思是“一定，准是”。Eg:The tall man must be your father.那个高个子男人一定是你的爸爸。以must开头的一般疑问句，它的否定回答用neednt（不必要），不用mustnt（不允许），mustnt常用于否定句中表示“不允许，禁止”。Eg:-Must I go there on foot?我必须得走过去吗？ -No,you neednt.不，你不需要。 You mustnt park your car here.你的车不允许停在这儿。【典型例题】Its very warm outside.You _wear the coat.A.have to B.hadnt C.dont have to D.mustnt3.情态动词can的用法： 表示能力：会能，在第上册中已经学习这种用法 Eg:Can you play the guitar? 你会弹吉它吗Judy can speak a little Chinese. 朱蒂会说一点中文。 I can dance and sing. 我能唱歌又能跳舞。 表示允许、许可：可以、能即在这一课中新学的词义 Eg:Can the students run in the hallways? 学生们可以在走廊上跑吗We can eat outside. 我们可以在外面吃东西。Can I come in? 我能进来吗 注意：同样是情态动词can 和have to 的用法是有区别的，和大部分情态动词一样，can在否定句中直接在can后加上not；在疑问句中把can放到主语前面，并且没有人称和数的变化，而 have to 是有相应变化的，详情请参照上一条。 【典型例题】The children _play football on the road.A.can B.must C.mustnt D.may-Must I clean the blackboard?-No,you _.A.neednt B.mustnt C.cant D.may notYour mother _there,she has gone to America.A.must be B.could be C.may be D.cant be4. 祈使句（Imperative Sentence）定义：用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句最常用于表达命令，因此在学校文法中也常称为命令句。祈使句因对象（即主语）是第二人称，所以通常都省略。祈使句的动词都为一般现在时，句末则使用句号或感叹号来表示结束。祈使句的肯定句：行为动词原形+其他Eg:Go and wash your hands.去洗你的手。命令 Be quiet, please.= Please be quiet.请安静。请求 Be kind to our sister.对姐妹要和善。劝告
