6、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.【考察点】can和could could为can的过去式 的根本用法1表示才能，如：He can speak English better than you. can和be able to都可表示才能，两者在意思上没有什么区别。但是can只能有如今式和过去式，而be able to那么有更多的形式，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

7、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“答应时can可以和may换用，如：You can may go home now.假如要表示语气婉转，可用could代替can，这时could不再是can的过去式，注意答复时不能用could。如：- Could you come again tomorrow?- Yes, I can./ No, I cant.3

8、 在疑问句和否认句中表示疑心、惊奇、不相信的态度。如：Can this green bike be Liu Dong's? 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 can be dull sometimes.2.【考察点】may和might might为may的过去式的根本用法1表示允许或答应，否认用mustnt, 表制止。如：- May we swim in this

9、lake? - No, you mustn't. It's too dangerous. 肯定可以用比较婉转的说法进展答复。如：- May I use this dictionary? - Yes, please. /Certainly. / Yes, you can.2在表示恳求、答应时，用might比may 语气更婉转些, 如：May I have a look at your new computer? May I?在文体上较正式，较客气，日常口语中常用Can I?3may或 might都可以表示可能性，表示"或许"、"可能"之意，

10、假如用might表示可能性，那么语气更加不肯定，如：They may might be in the library now. He is absent. He may/ might be ill.4May 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.【考察点】must的根本用法1must表示“必须、“应该之意，语气比should, ought to强烈，其否认式 must not，缩写形式为 mustnt，表示 “不准、或“制止之意

11、，如：We must study hard and make progress every day. You mustn't touch the fire. 2 对以must提出的疑问句，如作否认答复时，要用neednt或用dont doesnt have to 不必来答复，而不用mustnt，因为mustnt表示的是“制止或“不答应之意，如： - Must we finish the work tomorrow? - No, you needn't don't have to, but you must finish it in three days.3 must可以

12、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 Dong's. I know his father has just bought him a new one.You must be ill. I can see it from your face.4.【考察点】have to 的根本用法1have to和must的意义相近，只是 must侧重表示说话人的主观看法，而have to 那么表示客观需要，如：I must study hard.You have to hand in your co

13、mpositions before next Monday.2have to 有人称、数和时态的变化,否认式要用助动词，dont have to如：They had to speed up, for the weather turned terrible. He has to stay at home because of illness5.【考察点】should的根本用法1should表示“建议或“劝告，有“应该之意，可与ought to 互换。如：You should learn from each other. You should/ ought to go and see Mary s

14、ome 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 understand why you should think that I did it.4should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 shou

15、ld have given him more help.You shouldnt have left home without saying a word. 5 表示万一，用于if 从句Ask Tom to ring me up if you should see him.6.【考察点】will的根本用法1 可以表示“意志或“决心，如：I have told him again and again to stop smoking, but he will not listen. Can someone help me? I will.2恳求或询问对方的意愿，如：Will you please

16、tell me how to get to the Capital Gymnasium? Will you open the window?3表示一种习惯性的动作，有“总是或“惯于之意，will 指如今，would 指过去。如：Every morning he will have a walk along this river. 7.【考察点】would的根本用法1would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 promised he would never smoke again. 2 在疑问句中，用

17、于第二人称，表示说话人向对方提出恳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 English teacher would sometimes tell us

18、stories in English after class. / During the vacation he would visit me every week. 5 表料想或猜测，如：It would be about ten when he left home. What would she be doing there?I thought he would have told you about it.8.【考察点】shall的根本用法1 在疑问句中，shall用于第一、三人称，表示说话人的征询对方意见或恳求指示，如：Shall I open the door?2 shall用作情态

19、动词时，用于第二、三人称，表示说活人的意愿，可表示"命令"、"警告"、"强迫"、"威胁"或"许诺"等意，如：He shall go first, whether he wants to or not. 9.【考察点】need的根本用法1need作情态动词用时，主要用于否认句和疑问句中，如：He needn't worry about us now.  2need也可作为行为动词用，可用于肯定句、否认句和疑问句中，其后可接名词、代词、动名词或带 to 的动词不定式为其宾语。如：Y

20、ou need to practise reading aloud every day. 3needn't后接完成式可以表示过去做了一件本来不必要做的事情，如：- Did you answer the letter yesterday? - Yes, I did. - But you needn't have answered it.10.【考察点】dare的根本用法ldare dared为其过去式 作情态动词用时，主要用于否认句，疑问句和条件从句中，如：Dare he break the traffic regulations again? You will be punis

21、hed if you dare do such a thing.2在现代英语中dare常用作行为动词，其变化与一般行为动词一样，如：She dares to stay at home alone at night.知识点 3写作指导：三段式作文所谓三段式就是将一篇书面表达按三段的写作形式谋篇布局。三段式的形式写法通常为：1第一段开门见山，提出要解决的问题或观点，或者把时间、地点、人物和主要事情及时点出。2第二段要摆出事实或提出论据，或者把事情开展的经过详细写出来。3最后一段，得出结论或理由。注意：要学会使用过渡词。过渡词犹如“桥梁和“粘合剂。恰当地使用过渡词可防止构造松散，层次不明，表意不清等

22、弊端，使文章条理清楚，文字连接流畅。常用的过渡词有：1. 递进型：besides，whats more，worse still，moreover，even，furthermore等；Many of them can hardly look after themselves, still less manage their own life.他们很多人几乎不能照顾自己，更别说经营他们自己的人生。2. 解释型：in fact, as a matter of fact, actually, in other words, that is to say, that is等；He was once th

23、ought to be a boy who was not worth educating.

24、ience the future life on the Mars.相反，这些志愿者说，他们厌倦了地球上的生活，因此他们渴望体验将来火星上的生活。4. 列举型：firstly.secondly.finally，on the one hand，on the other hand等；On one hand, I can earn some money by doing it to help my parents, and on the other hand, I can gain some experience from it, which will do good to my future li

25、fe.一方面，我能通过做这样的事赚些钱来帮助父母；另一方面，我能从中获得一些经历，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

26、.一方面，我会组织一些英语活动，例如举办英语辩论赛或英语演讲比赛，目的是帮助我们学生进步英语方面的兴趣。6. 因果型：because of，since，therefore，as a result，thanks to，thus，due to等；Therefore, there is no reason for us to look down upon ordinary jobs.因此，我们没有理由轻视普通的工作。7. 让步型：though，although，in spite of，despite等；No matter who breaks the law, he will be punished

27、.不管谁违法都要受到惩罚。8. 顺序型：first.next.and then.finally，first.then.after that.finally等；Firstly, I collected all the books, newspapers and other things scattered in the rooms and put them in place. Then I wiped the dust off all the furniture. After that, I swept and mopped the floors.首先，我把所有的书籍、报纸和其他的散落在屋子里的

28、东西搜集起来放好，接着我扫去所有家具上的灰尘，然后我扫地、拖地。9. 并列型：and，or，also，as well as等；I think we will have a good time there and I will send your photos taken there.我想我们会玩得很愉快，而且我将会把在那里拍的你的照片送给你。10. 总结型：in conclusion，in a word，to sum up，in short，on the whole等；In a word, success is important, and so is failure, because its

29、 the mother of success.总之，成功很重要，失败也很重要，因为它是成功之母。12. 见解型：in my opinion，personally speaking，as far as I am concerned等。As far as I am concerned, they stand for love, friendship and unity.以我看来，他们代表爱、友谊和团结。以上写作形式可时常运用于实际的写作过程中，只要我们把握好写作技巧和形式，书面表达才能的进步也就指日可待了。四、例题精析【例题1】Many houses near the airport were d

30、estroyed by the wind.Well, the wind _ have been very strong.【答案】must【解析】机场附近的很多房子都被风破坏掉了。哦，那场风一定很大。must表示推测常用于肯定句。【例题2】If Doric continues doing things like that, he _ face the music one day!【答案】shall【解析】考察情态动词。句意：假如Doric继续做这样的事情，那么他一定会自食苦果的。face the music“承担后果。此处shall用在第三人称he后表示说话人的警告。再如：He shall st

31、ay in bed.他必须躺在床上。【例题3】Please dont tell anybody.I _.I promise.Acant BdontCwont Dmustnt【答案】选C【解析】考察情态动词的用法。句意：“请别告诉任何人。“我不会的，我保证。cant“不可能；不可以；dont助动词，表示否认；wont“不会的；mustnt表制止。根据句意，选C项。【例题4】She looks very happy. She _ have passed the exam.I guess so. Its not difficult after all.Ashould BmustCcould Dmig

32、ht【答案】选B【解析】考察情态动词。句意：“她看上去很开心。她一定是通过了考试。“我想是吧，毕竟考试不难。四个备选项都可以用来表示推测，must语气最强，然后是should, could, might语气最弱。根据语境，说话人推测她通过考试是有一定的理由的，即她看起来很开心，因此推测时很有把握，故用must。【例题5】假设你是李越，你的加拿大笔友Steve来信说，他和他的一些同学正在学中文，请你推荐两本学中文的词典。根据下表提供的信息，请你给他写一封回信。英汉词典新华字典收词字18 000 英语20 000 汉语10 000价格52元11元特点大量例子、用法说明，合适初学者中国最常用的汉语字

53、探险者，但我们在过去的十年里完成了从未有过的最伟大的远征。根据句意可知，这里应该填情态动词表示推测。对过去情况的推测应使用情态动词的完成式；表示不非常有把握的否认推测不能使用mustnt. 而neednt和shouldnt加动词的完成式一般不用于表示推测。所以B项may not“可能不是正确答案。4. C 解析should have done意为“本应做某事但没做；could have done意为“可能做了某事；neednt have done意为“没有必要做某事但却做了。根据句意可知C项最正确。must表推测时不能用在否认句中。5. C 解析此题考察情态动词的用法。A项指“制止；B项有“命

C 解析考察情态动词的用法。句子的意思为“想要找一本书，你不一定要知道作者的名字，你通过书名也能找到。由题意可知应选C项。8. C 解析考察情态动词的用法。由题干中的for可知，此处要用表示推断的情态动词。注意：must arrive用来对如今或将来的情况进展推断；can have arrived只用于疑问句或否认句中；must have arrived用来推断过去的情况；has arrived是一种客观陈述。9. B 解析考察情态动词的用法。must必须；一定。句意为“我们全家人都盼望见到你。这个周末，你一定要来和我们一起吃晚饭。如：I must shut the door，or the rain will come in. 我必须把门关上，不然雨就进来了。10. A 解析考察情态动词的用法。答句句意为“由于某种原
