1、课题:动词在中考单项选择题中的常见考点研究 专题二:情态动词中考考点、典型题、真题 负责人: 高靓初中英语情态动词考点解析【情态动词知识梳理】情态动词有具体的词义,但也同助动词一样,需要与其他词语一起构成句子的谓语,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。考点一:can,may,must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may和must均不可代替它。如:She can swim fast, but I cant . (2).表示许可,常在口语中。如:You can
2、 use my dictionary. (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?No, it cant be our teacher. He is on a visit to the Great Wall.2. could的用法:(1).can的过去式,意为“能、会”,表示过去的能力。如:He could write poems when he was 10. (2). could在疑问句中,表示委婉的语气,此时could没有过去式的意思。如:Could you do me a favour?Could
3、I use your pen?Yes, you can.(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? You may go home now. (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 . She may be at home. (3) .may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. (4) . 表示希望、祈求、祝愿,常可译为“祝愿”。通常是用ma
4、y +主+V例如:May you have a good time. May you be happy! May you succeed!4. must的用法:(1).must表示主观看法,意为“必须、一定”。如:You must stay here until I come back. Must I hand in my homework right now? (2)其否定形式mustnt表示“一定不要” “千万别” “禁止,不许”.如:You mustnt play with fire. You mustnt be late.(3)对must引导的疑问句,肯定回答为must,否定回答为ne
5、ednt 或dont have to .如:Must I finish my homework?No, you neednt. (4)must表示有把握的推测,用于肯定句。如: The light is on, so he must be at home now.注意其反意问句的构成形式:当must表示肯定的判断、推测时,其反意疑问句要用实际问句的助动词来构成。如:She must have seen the film before,hasntshe?(注意反意疑问句的后半部分)You must have met uncle Wang in the shop yesterday,didnt y
6、ou? (注意反意疑问句的后半部分)5. need的用法:(1).need表示需要、必须,主要用于否定句和疑问句中,其否定形式为neednt,意为“没有必要,不必”。用need提问时,肯定回答为must,否定回答为neednt或dont have to。如:Need I stay here any longer?Yes, you must .No. you neednt /dont have to.(2).need还可以作实义动词,此时有人称、数和时态的变化,如果是人作主语后边多接动词不定式。如:I need to do it right now. 如果是物作主语,一般用need doing与
7、need to be done这种情况下应注意两点:.主动形式的动名词doing具有被动的含义;.该动名词可以改为其动词不定式的被动形式而句子的意义不变。例如:. The door needs painting. = The door needs to be painted. 6. dare的用法:dare意为“敢、敢于”,用法近似于need,有两种词性:(1)dare作为情态动词,多用于否定句、疑问句或条件句中,无第三人称单数形式,只有一般现在时和一般过去时。如:Dare he tell them what he knows? I darent ask her will you do it
8、for me?(2)dare作为实义动词,此时有人称、数及时态的变化。如:He doesnt dare to break his promise.注意:口语中,dare的各种形式常与不带to的不定式连用。如:Do you dare tell her what I said?7. shall的用法:shall表示征求对方意见(多用于第一、三人称),如:Shall we go out for a walk?8. should的用法:(1).should意为“应该”,可表示劝告、建议、义务、责任等。如:We should protect the environment.(2)Should have
9、done表示对过去动作的责备、批评。如:You should have finished your homework.9. will的用法:will表示意愿、意志、打算,可用于多种人称。如:I will help you if Im free this afternoon.10. had better的用法:had better意为“最好”,没有人称的变化,后面接不带to的不定式,其否定形式为:had better not。如:We had better go now.考点二:含有情态动词的疑问句的回答:1.对may引出的问句,可以有下列回答方式:Yes,you may. Yes, of co
10、urse.Yes, certainly.Sure .No, you mustnt. No, you cant.2.对must引出的疑问句,回答方式为:Yes, must. No, neednt/ dont have to.3.could在疑问句中,表示委婉的语气,此时could没有过去式的意思。如:Could you do me a favour?Could I use your pen?Yes, you can.(注意回答)4. shall引出的疑问句用于第一人称,表示征求对方意见或客气的请求。其回答方式有以下几种:Yes, please.All right.No, thank you.5.
11、would you的回答方式有以下几种:Yes, I will. (No, I wont.)Sure . (Im sorry , I cant.)All right/ OK/ With pleasure.Certainly. (No, thank you .)Yes, please.考点三:不同情态动词的否定意义也不同:1.(1).cant可译为“不会”,如:I cant play basketball.(2)当句子表推测时,用cant表达不可能,如:He cant be ill. He is playing chess with Tom.(3)cant还可用来回答“ May I ? ”这样的
12、问句。如:May I come in ? No, you mustnt. / cant.(4)cant还可用于固定习语中。cant help doing禁不住,情不自禁cant wait to do something迫不及待地要做2. may的否定式为may not,译成“可能不”,如:He may not be at home.3.(1)mustnt表示不许,不可。如:He mustnt leave his room.(2) mustnt也可用于以may表示要求时的否定回答中。如:May I stand here?No, you mustnt (cant).4.(1)neednt意为“不必
13、”。如:You neednt meet him unless youd like to.(2)neednt + have+动词的过去分词,表不需要完成但已完成的动作,暗含时间或精力上的浪费。如:You neednt have bought it.你没必要买它(但你却买了)。5. shouldnt表示不应该。如:You shouldnt feel so unhappy over such little things.考点四:情态动词的被动语态含有情态动词的被动语态的结构为:情态动词+ be + done (动词的过去分词)。做题时要兼顾情态动词和被动语态这两个方面。考点五:情态动词表示推测的用法
14、:一、“情态动词+动词原形”表示对现在的推测。1、can表示推测时一般用于否定句或疑问句。如:That man cant be her husbandshe is still single.2、must表示肯定的推测,一般用于肯定句中。如:He must be in his office now.3、might表示推测时不一定是may的过去时,只是表示其可能性较小。如:The man may be the headmaster.4、Could表示推测时,语气can比要弱,说话者留有余地。如:Could it be an animal?It could not be,because it is
15、not moving.5、Should表示推测的可能性比较大,仅比must的可能性小一点。如:It is already 10 oclock now they should be there.二、情态动词表示对过去可能发生的动作或存在过的动作的推测性用法。1、“must +have done/been-”表示“过去一定发生过某事或存在过某种状态”,不用于“musnt+have-”形式。如:She must have seen the film before,hasntshe?(注意反意疑问句的后半部分)2、“should +have done /been-”表示“本应当做某事,而实际上并没有做
16、”;“shouldnt+完成式”表示“本来不应当做,而实际上却做了”。以上结构常带有说话者的责备的感情色彩。如:You should have finished your homework earlier (but in fact you did not finish it on time).3、“neednt+完成式”表示“本来没有必要做某事,而实际上却做了”。如:There was plenty of time. She neednt have hurried .4、“cant /couldnt+have done /been-”表示“过去不可能发生了某事或存在过某种状态”。如:I saw
17、 him just now. He cant have gone to Japan.5、“could+have done/been-”表示“过去本来能够,可以做某事或成为某种状态,而实际上没有”,说话者有些遗憾。6、“may/might+完成式”表示“过去可能,本来可以于某事而实际上没有干”,might的可能性较小,语气较弱。如:He may have finished reading the book. 【情态动词易混点归纳】易混点一: can和be able to:两者表示能力时用法相同,但can只有原形“can”和过去式“could”两种形式,在其他时态中要用be able to来表示。
18、另外be able to常常指经过努力,花费了时间和劳力之后才能做到某事。易混点二:can和may1. can和may均可用来征求意见或许可,意为“可以”,一般可互换使用。如:Can/ May I help you ? 我能帮助你吗?2. can和may表示可能性时的区别:1)在肯定句中用might,may,must,不用can2)在疑问句中表示推测用can,不用might,may,must3)在否定句中用cant(不可能),不用may,must。如:She may be in the classroom .她可能在教室里。Where can they be now?他们现在可能在哪儿?Tha
19、t cant be true.那不可能是真的。易混点三: may be和maybe 用法区别 常用位置may be may为情态动词,be为动词原形 句中,作谓语maybe 副词,大概、也许,相当于perhaps 句首,作状语例如:He may be wrong , but Im not sure.也许他错了,但我也不确定。易混点四:cant和mustnt1. cant根据其基本用法可译为:(1)不会。如:I cant speak English .我不会说英语。(2)不能。如:We cant do it now because its too dark.天太黑了,我们现在干不了。(3)否定句
20、中表示推测。“不可能”,如:The man cant be our teacher because he is much younger than our teacher.。2. mustnt意为“禁止、不许”,用来表达命令,表示强烈的语气。如:You mustnt play football in the street. Its too dangerous.易混点五:must和have to1.must侧重于个人意志和主观上的必要。have to侧重于客观上的必要,可用于现在时、过去时和将来时。易混点六: used to do / be used to doing / be used to
21、do/ be used for doing sthused to do表示过去常常发生的动作,强调过去,只用于过去;而be used to doing意为“习惯做”;be used to do意为“被使用去做,”为被动语态形式。be used for doing sth“用作”教学中的典型题集1. -Mum, may I watch TV now?-Sure, but you _ help me with my English.A. can B. may C. must D. could2. -_ I download the article again?-No,you neednt.A.
