1、2022-11-27八年级英语上 新目标 人2022-11-27一、情态动词一、情态动词cancan2022-11-27项目内容例句情态动词can的用法can是一个最常用的情态动词,经常用来表示请求、能力、推测等。can本身具有一定的含义,但不能独立作谓语,其后接动词原形,can的否定形式为cant。Can you help me?你能帮助我吗?They cant come to your party.他们不能来参加你的聚会。表示能力,意为“能;会”。Can you make a model plane?你会做飞机模型吗?表示许可,意为“可以”,相当于may。此外,could与might也可以

2、用于表示许可,语气更委婉。Can I read your newspaper?我能看看你的报纸吗?表示可能性,意为“可以;可能”。He can be very friendly at times.有时他会很友好。用于提出邀请,对其作肯定回答通常用Sure/Yes,Id love to;作否定回答则用Sorry/No,I cant。Can you come to my party?你能来我的聚会吗?Yes,Id love to.是的,我愿意去。2022-11-27can与beable to的区别can为情态动词,无人称和数的变化,过去式为could;而be able to有人称、时态和数的变化,

3、be able to可以与情态动词连用,后面接动词原形,而can不能这样使用。I hope to be able to go to the movies with you on Sunday.我希望星期日能和你一起去看电影。He will be able to finish the work.他将能完成这项工作。be able to的过去式还表示经过努力而做到,而could无此意思。He studied hard and was able to pass the exam.他努力学习,考试及格了。当表示猜测、请求和允许时,只能用can,不能用be able to。He cant be at h

4、ome now.他现在不可能在家。当表示现在或过去的“能力”时,两者可互换。I can dance.=I am able to dance.我会跳舞。返回返回2022-11-27二、二、have tohave to和和mustmust的用法的用法1.have to有人称、数和时态的变化,而情态动词must没有。have to的一般过去时的肯定式是had to,否定式是didnt have to;一般现在时第三人称单数的肯定式用has to,否定式用doesnt have to。have to must2022-11-27She has to help her mother do the hou

5、sework at home.她不得不在家帮助妈妈做家务。We must leave now.我们现在必须离开。We had to stay at home because it rained.因为下雨,我们不得不待在家里。He must look after his things.他必须照看好他的东西。2022-11-27I mustmust go now.我现在必须走。She has to clean the room every week.她每周都得打扫房间。2.have to和must都有“必须”的意思,但是have to侧重于强调客观条件需要做的事情,而must侧重于表示说话人的主观

6、看法,认为有义务、有必要去做某事。2022-11-27Do you have to study English now?你现在必须学英语吗?Must he do his homework now?他必须现在做作业吗?3.have to不能直接用来表示否定或进行提问,需要借助助动词;must的一般疑问句将其提前即可。2022-11-27You dont have to go there.你不必去那儿。You must not go there.你不许去那儿。4.在否定句中dont have to表示“没有必要”,must not表示“不允许”。2022-11-27Must the little

7、boy play with his brother?那个小男孩必须和他哥哥玩吗?No,he neednt.neednt.不,他不必。5.have to的一般疑问句回答用Yes,do/does/did.和No,dont/doesnt/didnt.。在回答must开头的一般疑问句时,肯定回答用must,否定回答用neednt或dont have to。返回返回Does she have to go now?她现在必须走吗?Yes,she does.是的,她必须走。2022-11-271.(2015福州中考)Doctor Wang,Im feeling much better.Must I go o
