    Unit 6 Electricity语法篇____________________________________________________________________________________________________________________________________________________________________学生学会canmaymust等情态动词的用法情态动词情态动词有具体的词义,但也同助动词一样,需要与动词原形一起构成句子的谓语,给谓语动词添加感情色彩,表示说话人对有关行为或事物的态度和看法,认为其可能,应该,必要等。另外情态动词没有人称和数的变化,情态动词后必须跟动词原形。 考点canmaymust等情态动词在陈述句中的用法: 1 can的用法: 1表示能力、许可、可能性。表示能力时一般译为能、会,即有种能力,尤其是生来具备的能力,此时maymust均不可代替它。如:She can swim fast, but I can’t . 她能游得很快,但我不能。I can see with my eyes.我用眼睛看。 2表示许可,常在口语中。如:You can use my dictionary.  你可以用我的字典。 3表示推测,意为可能,常用于否定句和疑问句中,此时cant译为不可能     如: Can the news be true?这个消息会是真的吗 —Can it be our teacher?那个人有可能是我们老师吗 —No, it can’t be our teacher. He is on a visit to the Great Wall.不可能。咱们老师正在游览长城呢。 【例题】—I think Miss Gao must be in the library. She said she would go there.         —No. She ____ be there, I have just been there.   2  could的用法1can的过去式,意为能、会,表示过去的能力。如:He could write poems when he was 10. 他十岁时就会写诗。 2could在疑问句中,表示委婉的语气,此时could没有过去式的意思。:Could you do me a favor? 你能帮我忙吗? —Could I use your pen?我能用一下你的钢笔吗? —Yes, you can.可以。(注意回答) 3 may的用法: 1表示请求、许可,比can正式,如:May I borrow your bike?我可以借你的自行车吗You may go home now.现在你可以回家了。 【例题】—_______ I borrow your MP3? —Sure. Here you are.  A. May   B.Should   C.Must   D. Would 2表示推测,谈论可能性,意为可能,或许,一般用于肯定句中。如:It may rain tomorrow .明天可能会下雨。She may be at home.她可能在家呢. 3may的过去式为might,表示推测时。可能性低于may如:He is away from school. He might be sick. 他离开学校了,可能是他生病了。 4表示希望、祈求、祝愿,常可译为祝愿。通常是用may ++V如:May you have a good time.祝你过得愉快。May you be happy!祝你幸福May you succeed!祝你成功! 4 musthave to的用法: 1must表示主观看法,意为必须、一定多用于肯定句或疑问句; have to则表示客观的义务或需要,可用于各种句子和时态如:You must stay here until I come back.在我回来之前你必须呆在这儿。Must I hand in my homework right now?我必须现在交作业吗 2must引导的疑问句,肯定回答为must,否定回答或dont have to .如:—Must I finish my homework?我现在必须完成作业吗 3must表示有把握的推测,用于肯定句。: The light is on, so he must be at home now.灯亮着,他现在肯定在家。注意:易错点:mustnt “禁止,表示不必要做某事“needn’t to do sth”.                     知识点:情态动词must用法例一—Mum, may I watch TV now?  —Sure, but you ________ finish your homework first.can       B. may       C. must   D. should解析:根据题意妈妈,我能看电视吗?”“可以,但是你应该先完成你的作业,应该用情态动词should.答案:D知识点二:must用法例二 —________ I download the article again?—No, you needn’t.Shall    B.
