新课讲解情态动词
情态动词的定义: 情态动词是一种本身有一定的词义,表示说话人的情绪,态度或语气的动词,但不能单独作谓语, 只能和其他动词原形构成谓语。
We can be there on time tomorrow. 我们明天能按时去那儿。May I have your name? 我能知道你的名字吗？
Shall we begin now? 我们现在就开始吗？You must obey the school rules.你必须遵守校规。
情态动词数量不多,但用途广泛,主要有下列:
can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) .
情态动词的位置: 情态动词在句中放在谓语动词之前, 谓语动词前若有助动词,则在助动词之前,疑问句中, 情态动词则在主语之前。
I can see you. Come here. 我能看见你，过来吧。He must have been away.他一定走了。
What can I do for you? 你要什么？How dare you treat us like that！你怎能那样对待我们！
情态动词的特点: 情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加"not"。个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去，现在或将来。
He could be here soon. 他很快就来。We can't carry the heavy box. 我们搬不动那箱子。
I'm sorry I can't help you. 对不起，我帮不上你。
１．Can/could
（１）can 一般表示体，脑力方面的能力，意为“能，会（做某事）”，也可用来表示客观的可能性，意为“可以，可能”。例如：He can swim in the river．I can do the work myself．
The boy can sing in English．I can help you with your housework．
（２）can ＼could 也可以用于疑问句，否定句中表示“猜测”。如：
He can't be at home.他不可能在家。
（３）can还能用来询问或请求一件事可以不可以做，常用于口语中，相当于may。例如：Can I help you? ＝May I help you?
can 的否定式是在其后加not，写为cannot 或can't。例如：You can't stay here you can go home now.（4）表示能力（体力、知识、技能）。
Can you lift this heavy box?（体力）
Mary can speak three languages.（知识）Can you skate?（技能）
此时可用be able to代替。Can只有一般现在时和一般过去式；而be able to则有更多的时态。
I’ll not be able to come this afternoon.
当表示“经过努力才得以做成功某事”时应用be able to，不能用Can。如：
He was able to go to the party yesterday evening in spite of the heavy rain.
(5)表示请求和允许。
-----Can I go now? ----- Yes, you can. / No, you can’t.
此时可与may互换。在疑问句中还可用could,
might代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。
---- Could I come to see you tomorrow? ---- Yes, you can. ( No, I’m afraid not. )
(6)表示客观可能性（客观原因形成的能力）。
They’ve changed the timetable, so we can go by bus instead. This hall can hold 500 people at least.
(7)表示推测（惊讶、怀疑、不相信的态度），用于疑问句、否定句和感叹句中。
Can this be true? This can’t be done by him. How can this be true?
２．May/ Might
（１）may一般表示“请求，许可，允许”。例如：
—May I come in﹖—Come in please.
—May I go home now﹖—Yes, you may.
You may only keep the books for two weeks．这些书你只可以借两个星期。
（２）may可以用来表示“猜测，推测”。例如：
Our head teacher may be in the office．我们的班主任可能在办公室。
（３）may还能用来表示“希望，祝愿，渴望，请求和应该”。用于祈使句，表示祝愿。例如：May you be happy！祝你幸福！May you succeed!
（4）表示请求和允许。might比may语气更委婉，而不是过去式。否定回答时可用can’t
或mustn’t，表示“不可以，禁止”。
----Might/ May I smoke in this room? ---- No, you mustn’t.
---- May/Might I take this book out of the room? ---- Yes, you can. (No, you can’t / mustn’t. )
用May I...？征徇对方许可时比较正式和客气，而用Can I...？在口语中更常见。
表示推测、可能性（不用于疑问句）。might不是过去式，它所表示的可能性比may小。
He may /might be very busy now. Your mother may /might not know the truth.
３．Must/ have to
（１）must表示义务，禁止和推测，意思是“必须，应该，应当，一定是，务必要”等。例如：
I must do my homework at once．We must speak more English．
You must help each other．It's ten now my mother must be angry.
（２）在回答must的疑问句时，其否定形式多用needn't来表示“没必要，不许”。例如：
—Must she answer the question in English﹖—No, she needn't．
注意：mustn't 经常表示绝对禁止，语气强烈。如：You mustn't do it again．你再也不能这样做了。（３）must在表示猜测，推测时，否定式常用can't代替。例如：
The students of Class Three must be having a good time in the park．三班的学生一定在公园玩得很高兴。Tom must be in the classroom．汤姆一定在教室里。He cannot be ill．他不可能生病。（4）must是说话人的主观看法，而have to则强调客观需要。Must只有一般现在时，have to 有更多的时态形式。Her play isn’t interesting, I really must go now. I had to work when I was your age.
3) 表示推测、可能性（只用于肯定的陈述句）
You’re Tom’s good friend, so you must know what he likes best.
Your mother must be waiting for you now.
4 . ought to， should
ought to 和 should 都可译为“应该”，但它们之间还是有点区别。
◆ ought是一个情态动词，意为“应该，理应”表示义务和责任。无人称、时态和数的变化，后接带to的不定式，如果是ought to have done形式则是表愿望。
eg：You ought to obey your parents．他应该服从你的父母。
It occurred to him that he ought to go and see her．他曾想到了自己应该去看看她。
You ought to have locked the door when you went out．你外出的时候应该上门。
◆ should作情态动词时，意为“应该，应当”表示建议，无人称、时态和数的变化，它的语气比ought to弱；should have done 形式多用于与过去相反的虚拟结构中。
eg：You should do it for your own good．为了你自己的好处，你应该做那件事。
You shouldn't come to such a decision hastily．你不应该仓促(草率)地做出这样一个决定。
I should have bought it if I had enough money．如果我当时有足够的钱的话，我就会把它买下来
5. shall
1) shall 用于第一人称，征求对方的意见。What shall we do this evening?
2) shall 用于第二、三人称，表示说话人给对方的命令、警告、允诺或威胁。
1. You shall fail if you don’t work hard.(警告)
2. He shall have the book when I finish it.(允诺)
3. He shall be punished.(威胁)
6. will, would
1) 表示请求、建议等，would更委婉。Will / Would you pass me the ball, please?
2) 表示意志、愿望和决心。1. I will never do that again. 2. They asked him if he would go abroad.
3) would表示过去反复发生的动作或某种倾向。would表示过去习惯时比used to正式，且没有“现已无此习惯”的含义。1. During the vacation, he would visit me every other day. 2. The wound would not heal.
4) 表示估计和猜想。It would be about ten o’clock when she left home.
四、情态动词的辨析
（一）can 和could
1.表示能力，意思是“能，会”。
2.表示请求、允许，意思是“可以”。
3.表示可能性。通常用在否定或者疑问句中.could 为can的过去式，比can的可能性要小。如：
He can swim, but i can't. You can use my dictionary.
The coat can't be hers. Hers is white. Could you help me, please?
4.表能力时，could 和can枝用于现在时和过去时，其他时态一般用be able to来表达。如：
With the teacher's help, i shall be able to speak English well.
（二）shall, should, ought to ,must, have to
1.shall表示征询意见，主要用于第一人称的疑问句中。如：Shall i take you to the hospital? Shall we go now?
2.should 和ought to
都有“必须，应该”的意思。当强调道义或法律所规定的职责时用ought to; 如果是说话者的一种主观看法时，则用should.如：
We should speak English in our English class every day. You ought to bring the children here.
3.must 和have to
都有“必须”的意思，must是表示说话者的主观愿望；have to 则侧重于客观上的必要，意为“不得不，只得” ，如：I must take good care of the pets. When the traffic lights turn red, i have to stop the car.
4.must还表示推测，意为”一定，准是“。如：
The lady must be a doctor.
5.should 和ought to在“should/ ought to + have+过去分词”结构中，表示应该做某事但实际上未做。其否定机构是“should not / ought not to + have+过去分词” ，表示不应该做某事但实际上做了。如：
You should have been here yesterday. You ought not to have taken the book out of the reading-room.
6.在“must + have + 过去分词”结构中，表示对过去的肯定猜测，意思是“肯定做过某事”。如：
He must have told my parents about it.
（三）will 和would
1.表示决心、愿望。意思是“愿意，将会” 。如：I'll do my best to catch up with them.
I'll never do it again; that's the last time. He would help me with my maths.
2.在疑问句中，will 和would都可以表示说话人向对方提出请求或询问，但是would比will更婉转。如：
It's hot. Will you open the window? Will you help me to work it out?
（四）、may 和might
1.表示可能性，意思是“可以” ，暗含较强的不确定语气。might 比may的可能性更小。如：
She may go there tomorrow. He said he might lend us some money.
2.表示允许或者是征求同意，多用于肯定句和疑问句中。如：
You may take the book home. She might help if she knows the truth.
1．might是may的过去式，语气更加委婉、客气和对可能性的怀疑。如：
2．He told me he might be here on time. He might be alive. Might i borrow any money now?
（五）、need 和dare
1.need的意思是“需要，必要”。作情态动词时，后直接跟动词原形，变否定时，直接在后面加“not”，变疑问句时，直接提到主语之前。如：You needn't come if you are busy. Need i hand in the paper this week?
2.dare的意思是“敢” 。作情态动词时，后跟动词原形，变否定时，直接在后面加“not”，变疑问句时，直接提到主语之前。如：The little girl dare not speak in public. Dare you catch the worms?
3.need 和dare还可作实义动词用。作实义动词时，与与普通实义动词一样，有第三人称单数形式。变否定时要在前面加“don't, doesn't, 或didn't” 。变疑问句时，不能提前，而是在主语前面加“do, does, 或did” 。如：
She needs a necklace. You don't need to attend the meeting. Do you dare to walk in the dark？

情态动词用于虚拟语气中表示责备的感情色彩，用法如下：
（1）should have done表示“本来应该做某事而实际上未做”，而shouldn’t have done则表示“本不应该做某事而实际上做了”。如：You should have told me about it earlier.
You shouldn’t have said such words to your parents.
（2）ought to have done也表示“本应该……”而ought not to have done则意为“本不应该……”。如：
You ought to have told me about it earlier.
You ought not to have said such words to your parents.
（3）needn’t have done表示“本无必要做某事而实际上做了”。如：
You needn’t have walked so quickly since time was enough.
（4）could have done表示“本来有可能……而事实上未做到”。如：
I could have come on time, but my car broke on the way.
二、精典名题导解
1. I was really anxious about you. You________home without a word.
A.mustn’t have
B.shouldn’t have left
C.couldn’t have left
D.needn’t have
解析：答案为B。本题考查的是情态动词在虚拟语气中的用法。题目给出的条件是“我确实非常担心你”，因此后面可知应是责备you不应该没说一句话就离开了。
2.—Are you coming to Jeff’s party?
—I’m not sure. I__________ go to the concert instead.
A.must
B.would
C.should
D.might
解析：答案为D。本题考查情态动词的基本用法。由题目中“I’m not sure”,表明我可能去Jeff’s party，也可能去音乐会，故用might。
3. —Will you stay for lunch?
—Sorry, ____________. My brother is coming to see me.
A.I mustn’t
B.I can’t
C.I needn’t
D.I won’t
解析：答案为B。本题考查表示请求的英语口语，用will来向第二人称提问的疑问结构，是表示一种请求和意愿，是用疑问的形式来表达较为婉转的祈使语气，意思是“请你……，好吗”，对于这种问句的肯定回答是：Suree! Gertainly! Yes, of course. I’d be glad to 等；否定回答通常是：I’m sorry, I can’t. No, I’m afraid I can’t. I’m sorry, but … I’d like to, but …等。注意情态动词表客气的用法及其在一般疑问句中的问与答。
4.—Isn’t that Ann’s husband over there?
—No, it be him I’m sure he doesn’t wear glasses.
A. can’t
B. must not

5.You be tired－you’ve only been working for an hour.
A. must not
B. won’t
C. can’t
D. may not
解析：答案为C。句中破折号后的内容对前一句进行解释说明：你只工作了一个小时，所以你不可能累的。表否定推测时用can’t。A项表禁止（不许），B项表未来，D项表不允许。均不可用，故选C。
6.I often see lights in that empty house. Do you think I report it to the police？
A. should
B. whatever
C. whichever
D. whenever

情态动词 一、课前热身： 二、内容讲解： 知识点一、【情态动词】又叫情态助动词。它们具有以下特点： ⑴它们必须与其他动词连用，即：情态动词＋动词原形 表示说话人对所述动作的看法，如需要、可能、意愿或怀疑等。 ⑵绝大多数情态动词没有人称和数的变化，即第三人称单数不加-s （以be和have 开头的情态动词短语除外）。 ⑶在意义上，情态动词具有“多义性”。 例：can既可表示能力，又可表示可能、允许等意义。 知识点二、【情态动词的基本用法】 1. can的基本用法： ⑴表示体力或智力上的能力，即“能够，会”，可与be able to转换。 例：He can speak English. = He is able to speak English. —Can you play basketball? — No, I can’t. 如果表示将来具备的能力，要用will be able to。 例：If I have a good sleep, I will be able to do the problem. ⑵表示许可，主要用于口语，书面语一般用may。
例：—Can we go home now, please? — No, you can’t. You can only smoke in this room. You can’t keep the library books for more than a month. ⑶表示“可能”，与may同义，但一般用在疑问句中。 例：What can he possibly want? 在否定句中，否定形式can’t表示推测“不大可能”。 例：Anybody can make mistakes. The news can’t be true. 与第一、二人称连用时，还可以就可能的解决问题的方式或可能的行为提出建议。在这里，也可用could使语气婉转。 例：Can / Could we meet again next week? 下周我们可以再见面吗？ —What shall we do? 我们怎么办呢？ — We can / could try asking Lucy for help. ——我们可以请露茜帮忙试试看。 You can / could help me with the cooking. 你可以帮我做饭。 2. may的基本用法: ⑴表示“许可”，用can比较口语化。 例：You may / can come if you wish. 如果你想来，你就来。 You may not pick flowers in this park. 本公园内不许摘花。 （may not表示按规定不许可，如果用mustn’t则表示说话人不许可。） 我可以在这里抽烟吗？ —mustn’t表示明确的禁止。） ⑵肯定句中表示推测，“可能”。 例：It may rain tomorrow. 明天可能会下雨。

情态动词 教学目标：情态动词的用法 教学内容：常见情态动词用法 概念表示人的情绪与态度 常见的情态动词 Had better, should, ought to 1.表示建议时had batter语气最强，ought to 最弱 2. 表示推测。注意与must表示推测时的区别： He must be at home by now. （断定他已到家） He ought t o be home by now. （不十分肯定） T his is where t he oil must be. （比较直率） T his is where t he oil ought t o be. （比较含蓄） 3. “ought to + have + 过去分词”表示过去应做某事而实际未做。如： You ought to have asked him (but you didn't). 这时，ought t o和should可以互相换用。 4. Should的含义较多，用法较活，现介绍三种其特殊用法。请看下面的句子： I should think it would be better t o t ry it again. 我倒是认为最好再试一试。 You are mistaken, I should say. 依我看，你是搞错了。 I should advise y ou not to do that. 我倒是劝你别这样做。 T his is somet hing I should have liked to ask you. 这是我本来想问你的。 从以上例句可以看出：情态动词should用于第一人称时可以表示说话人的一种谦逊、客气、委婉的语气。 此外，Why(or How) + should结构表示说话人对某事不能理解，感到意外、惊异等意思。意为“竟会”。如： Why should you be so lat e today? 你几天怎么来得这么晚？ — Where is Betty living? —贝蒂住在哪里？ — How should I know? —我怎么会知道呢？ I don't know why you should think that I did it. 我真不知道你凭什么认为这件事是我干的。 5. “should + have + 过去分词”结构一般表示义务，表示应该做到而实际上没有做到，并包含一种埋怨、责备的口气。如：She should have finished it. I should have helped her, but I never could. You should have st arted earlier. Must, have to, have got to 1. must表示的是说话人的主观看法，而have t o则往往强调客观需要。如： T he play is not int erest ing. I really must go now. 这部剧没意思。我真的必须现在就走。 I had to work when I was your age. 当我像你这么大时，我不得不工作。 2. 否定意义不大相同。如：
情态动词can的教学设计 发布者：付贤彦 教学目标： 1.知识目标：掌握本课的大纲词汇和情态动词can的用法。 2.能力目标：1）能听懂会不会那些体育运动项目话题的有关的简单会话。 2）能用can或can…t表述会不会那些体育运动项目。 3.文化意识：了解国内外常见的体育运动项目，以及运动项目的种类。 4.学习策略：培养学生在大信息量（许许多多的运动项目中）的语言活动中搜索处理语言信息，发现，归纳学习重点，从而掌握本单元重点学习内 容。 教学内容： 1.大纲词汇sport, throw, race, field, 新课标词汇high jump, long jump, event, track 2.句型he can / can?t … 教学重点：用情态动词can表示会不会那些体育运动项目的句子 教学手段：多媒体。 教学步骤 教学第一个环节：创设情景，导入新课 1. 将有关表示体育运动项目的图片由运动员进行曲连接起来，向 学生们展播，从而引出sports meeting和sports event词汇。 2. 要求学生以brainstorm的方式说出what sport they know 3.把学生已知和未知的有关体育运动项目的 图片和单词卡片给学生（4人一组）把词
与图联系起来。 (这是学生们做练习的情景) （以下是课堂练习内容） baseball skate swim basketball badminton ski football 100-meter hurdles high jump tennis surf table tennis long jump 100-meter race shot put long jump 4. 学习新单词 throw the shot put do the high jump do the long jump do the 200 –meter run run the 110-meter hurdles 5. 检查单词 1）个人或集体朗读单词。 2）做游戏（根据老师所给的图片一人比划另一人猜出这个单词或一人用英语说出图片的意思另一人猜出这个单词。（3组练习）设计意图：教材1.1中教学内容生词量较大，平时又很少遇到，学习起来比较枯燥，难以记住。但用音乐将图片连接起来，充满激情的音乐营造了欢快的学习气氛，使学生情绪高涨，同时又陶冶了学生的情操。说出已知的单词和图与词连接的练习，可以展示学生自主学习的成果。让学生听着音乐，看着图片，在不知不觉中学习了单词，并自然而然地让学生融于英语学习的情境中，大大激发了他们的学习兴趣，又以游戏的形式检查单词，有趣的画面，难忘的表演，吸引了学生的注意力加深了他们对单词的 印象。为后面的学习内容打下了基础 在这个教学环境中，学生是活动的主体，教师只充当了“节目主持人”的角
