6、词概念:在动词(一般动词)之前形成动词的否定,疑问,时态,语态,语气或表示特殊意义的动词叫做助动词,其中具有感情色彩一些助动词叫做情态动词。情态动词是一种本身有一定的词义,但要与动词原形及其被动语态一起使用,给谓语动词增添情态色彩,表示说话人对有关行为或事物的态度和看法,认为其可能、应该或必要等。情态动词后面加动词原形。知识点2 情态动词分组辨析:1.【考查点】can和could (could为can的过去式) 的基本用法(1)表示能力,如:He can speak English better than you. can和be able to都可表示能力,两者在意思上没有什么区别。但是can
7、只能有现在式和过去式,而be able to则有更多的形式,可位于情态动词之后或表达过去成功地做了某事。如:He will be able to do the work better.He was able to finish the work on time.(2) 表示客观的可能性Accidents can happen to any drunken driver.According to the radio, it could rain this afternoon. (3)表示“许可”时can可以和may换用,如:You can (may) go home now.如果要表示语气婉转,
8、可用could代替can,这时could不再是can的过去式,注意回答时不能用could。如:- Could you come again tomorrow?- Yes, I can./ No, I cant.(3) 在疑问句和否定句中表示怀疑、惊奇、不相信的态度。如:Can this green bike be Liu Dongs? How can you believe such a liar like him?(4) 用于肯定句,表示一时的情况,意为:有时候会。如:It can be very hot here in summer.Tom is a clever boy, but he

10、r new computer? May I?在文体上较正式,较客气,日常口语中常用Can I?(3)may或 might都可以表示可能性,表示或许、可能之意,如果用might表示可能性,则语气更加不肯定,如:They may (might) be in the library now. He is absent. He may/ might be ill.(4)May 用于祈使句,表示祝愿。如:May you have a happy life.May you succeed.比较Wish you a happy new year. Wish you success.3.【考查点】must的基

(2) 对以must提出的疑问句,如作否定回答时,要用neednt或用dont (doesnt) have to (不必)来回答,而不用mustnt,因为mustnt表示的是“禁止”或“不许可”之意,如: - Must we finish the work tomo
12、rrow? - No, you neednt (dont have to), but you must finish it in three days.(3) must可以表示推测,表示“一定”或“必定”之意,只用于肯定句中。如:- Whose new bike can it be?- It must be Liu Dongs. I know his father has just bought him a new one.You must be ill. I can see it from your face.4.【考查点】have to 的基本用法(1)have to和must的意义相近,
13、只是 must侧重表示说话人的主观看法,而have to 则表示客观需要,如:I must study hard.You have to hand in your compositions before next Monday.(2)have to 有人称、数和时态的变化,否定式要用助动词,dont have to如:They had to speed up, for the weather turned terrible. He has to stay at home because of illness5.【考查点】should的基本用法(1)should表示“建议”或“劝告”,有“应该”
14、之意,可与ought to 互换。如:You should learn from each other. You should/ ought to go and see Mary some time.(2)表示推测,译作:很可能,该,是说话人对客观事物的真实性做出较大可能性的判断。如:Its already 10. She promised to come by 10. She should be here at any moment.(3) why/how + should 表示“竟然”,含意外、惊异等语气。Why should you be so late today?I dont und
15、erstand why you should think that I did it.(4)should后接完成式表示过去没有做到本来应该做的事情,或是做了本来不应该做的事情。如:You should have given him more help.You shouldnt have left home without saying a word.

17、d作为will的过去式,可用于各人称,表示过去时间的意志或决心,如:He promisedhe would never smoke again. (2) 在疑问句中,用于第二人称,表示说话人向对方提出请求或许问对方的意愿时,比用will的气更加婉转,如:Would you like some more coffee? (3)在日常生活中,学用I would like to表示我想要或我愿意之意,以使语气婉转,如:I would like to do Ex.2 first. (4) would可以表示过去的习惯动作,比used to正式,并没有现已无此习惯的含义。如:Last year our

25、助父母;另一方面,我能从中获得一些经验,这会对我将来的生活有益。5. 举例型:for example,for instance,such as,that is,like,take.for example等;On one hand, I will organize some English activities, for example, to hold English debates or English speech contests so as to help us students arouse their interest in English.一方面,我会组织一些英语活动,例如举办英
