第五篇：情态动词教案
情态动词
【考纲解读】
情态动词与虚拟语气有千丝万缕的联系，它们往往放在一起考查。在近年高考题中，对情态动词的考查几乎每年都有纵观近几年的高考题可以看出，高考对情态动词的考查热点依次是：（1）推测和可能性；（2）“情态动词+have done”结构表示猜测或表示虚拟语气；（3）shall, should, can, must表示特定语气。尤其是对“情态动词+have done”结构的考查频率较高。试题的情景设置往往生动、真实，但考查的角度趋于细微化和综合化，有效信息较为隐蔽，这就决定了情态动词题是难题之一。情态动词题每年都考，所以本专题在高考中的重要地位是显而易见的。因而在复习中应引起高度重视，且依笔者之见，来年高考中对情态动词考查的可能性依然非常大。【知识要点】
一、情态动词的语法特征
1.情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。2.情态动词 除ought 和have 外，后面只能接不带to 的不定式。3.情态动词没有人称、数的变化，即情态动词第三人称单数不加-s。4.情态动词没有非谓语形式，即没有不定式，分词等形式。
二、情态动词的基本用法 1.比较can 和be able to 1)can could 表示能力；可能(过去时用could)，只用于现在时和过去时(could)。be able to可以用于各种时态。
They will be able to tell you the news soon.他很快就能告诉你消息了。2)只用be able to中情况： 位于助动词后； 情态动词后；
表示过去某时刻动作时； 用于句首表示条件；
表示成功地做了某事时，只能用was/were able to，不能用could。He was able to flee Europe before the war broke out.=He managed to flee Europe before the war broke out.战争爆发前，他就逃离欧洲了。
注意：could，在否定，疑问句中表示推测或怀疑。表示提出委婉的请求（注意在回答中不可用could）。
—Could I have the television on? —Yes，you can./No，you can’t.He couldn’t be a bad man.他不大可能是坏人。2.比较may和might
1)表示允许或请求；表示没有把握的推测；may 放在句首，表示祝愿。May God bless you!愿上帝保佑你！He might be at home.他有可能在家。
注意：might 表示推测时，不表示时态。只是可能性比may 小。
2)may/might as well，后面接不带to 的不定式，意为“不妨，还是……好”。You may(might)as well tell me the truth.你还是对我说实话好。3.比较have to和must
1)两词都是“必须”的意思，have to 表示客观的需要，must 表示说话人主观上的看法，即主观上的必要。
My brother was very ill，so I had to call the doctor in the middle of the night.我弟弟病得很厉害，我只得半夜里把医生请来。(客观上需要做这件事)
He said that they must work hard.他说他们必须努力工作。（主观上要做这件事）
2)have to有人称、数、时态的变化，而must只有一种形式。
He had to look after his sister yesterday.昨天他不得不照看他的妹妹。3)在否定结构中：
don’t have to 表示“不必”（可以不可以都行）；mustn’t表示“禁止” You don’t have to tell him about it.你不必把此事告诉他。You mustn’t tell him about it.你一定不要把这件事告诉他。4.must表示推测
1)must用在肯定句中表示较有把握的推测，意为“一定”。
2)must表对现在的状态或现在正发生的事情的推测时，must 后面通常接系动词be 的原形或行为动词的进行式。
You have worked hard all day.You must be tired.你辛苦干一整天，一定累了。（对现在情况的推测判断）He must be working in his office.他一定在办公室工作呢。比较：He must be staying there.他现在肯定在那里。He must stay there.他必须待在那里。
3)must 表示对已发生的事情的推测时，must 要接完成式。I didn’t hear the phone.I must have been asleep.我刚才没有听到电话，我想必是睡着了。
4)must表示对过去某时正发生的事情的推测，must 后面要接不定式的完成进行式。—Why didn’t you answer my phone call?
—Well，I must have been sleeping，so I didn’t hear it.5)否定推测用can’t。
If Tom didn’t leave here until five o’clock，he can’t be home yet.如果汤姆五点才离开这儿，他此时一定还未到家。5.表示推测的用法
can，could，may，might，must 皆可表示推测，其用法如下： 1)情态动词+动词原形
表示对现在或将来的情况的推测，此时动词通常为系动词。I don’t know where she is，she may be in Wuhan.我不知道她在哪儿，她可能在武汉。2)情态动词+动词现在进行时
表示对现在或将来正在进行的情况进行推测。
At this moment，our teacher must be correcting our exam papers.这时，我们老师想必在批改试卷。
3)情态动词+动词完成时表示对过去情况的推测。
We would have finished this work by the end of next December.明年12月底前我们很可能已完成这项工作了。The road is wet.It must have rained last night.地是湿的，昨天晚上一定下雨了。
4)情态动词+动词的现在完成进行时表示对过去正在发生事情的推测。Your mother must have been looking for you.你妈妈一定一直在找你。
5)推测的否定形式，疑问形式用can’t，couldn’t表示。
Mike can’t have found his car，for he came to work by bus this morning.迈克一定还没有找回他的车，因为早上他是坐公共汽车来上班的。
注意：could，might表示推测时不表示时态，其推测的程度不如can，may。6.情态动词+have+过去分词
1)may(might)have+done sth.can(could)have+done sth.表示过去，推测过去时间里可能发生的事情。
Philip may(might)have been hurt seriously in the car accident.飞利浦在那场车祸中有可能伤的很严重。
2)must have+done sth.对过去时间里可能发生的事情的推测，语气较强，具有“肯定”“谅必”的意思。
—Linda has gone to work，but her bicycle is still here.—She must have gone by bus.3)ought to have done sth.／should have done sth.本应该做某事，而事实上并没有做。否定句表示“不该做某事而做了”。
He ought not to have thrown the old clothes away.（事实上已扔了。）ought to 在语气上比should 要强。4)needn’t have done sth.本没必要做某事 I dressed very warmly for the trip，but I needn’t have done so.The weather was hot.那次旅行，我穿的非常暖和，但我本没有必要那么去做。天太热了。5)would like to have done sth.本打算做某事
I would like to have read the article，but I was very busy then.我本想读那本书，但我那时太忙了。7.should 和ought to
should 和ought to 都为“应该”的意思，可用于各种人称。—Ought he to go?
—Yes.I think he ought to.表示要求，命令时，语气由 should（应该），had better最好），must（必须）渐强。8.had better表示“最好”
had better 相当于一个助动词，它只有一种形式，它后面要跟动词原形。had better do sth.最好干某事
had better not do sth.最好不干某事
had better have done sth.表示与事实相反的结果，意为“本来最好”。9.would rather表示“宁愿” would rather do 宁可干某事
would rather not do 宁可不干某事 would rather...than...宁愿……而不愿
还有would sooner，had rather，had sooner都表示“宁愿”“宁可”的意思。I would rather stay here than go home.=I would stay here rather than go home.我宁可待在这儿也不回家。
10.will和would
1)would like；would like to do=want to 想要，为固定搭配。Would you like to go with me?你想和我一块儿去吗？
2)Will you...? Would you like...?表示肯定含义的请求劝说时，疑问句 中一般用some，而不是any。
Would you like some cake?要蛋糕吗？
3)否定结构中用will，一般不用would，won’t you是一种委婉语气。Won’t you sit down?你不坐吗? 11.情态动词的回答方式
must和need相同:Yes,...must.No,...needn't/don't have to may和can could相同:Yes,...may/can/could.No,...mustn't/...'d better not/can't.shall:Yes,...can/may.No,...can't.should:Yes,...should.No,...shouldn't.will和would差不多:Yes,...do/will.No,...won't/thanks.典型例题
1）---Could I borrow your dictionary?---Yes,of course,you____.A.might B.will C.can D.should 答案C.could表示委婉的语气,并不为时态.答语中of course,表示肯定的语气,允许某人做某事时,用can和 may来表达,不能用could或might.复习：will 与you连用,用来提出要求或下命令.should与you 连用,用来提出劝告.2）---Shall I tell John about it?---No,you ___.I've told him already.A.needn't B.wouldn't C.mustn't D.shouldn't 答案A.needn't 不必,不用.wouldn't 将不,mustn't 禁止、不能.shouldn't 不应该.本题为不需要,不必的意思,应用needn't.3）---Don't forget to come to my birthday party tomorrow.---______.A.I don't B.I won't C.I can't D.I haven't 答案B.will既可当作情态动词,表请求、建议、也可作为实义动词表“意愿、意志、决心”,本题表示决心,选B.12.比较need和dare
一、need表示“需要”或“必须”，作情态动词时，仅用于否定句或疑问句中，在肯定句中一般用must,have to,ought to，或should代替。多用在否定式或疑问句中.1.Need I attend the meeting tomorrow?
我需要明天参加会议吗? 2.You need not hand in the paper this week.这一周你不必交论文。
need 是一个情态动词，他的用法完全和其他情态动词一样，但 need 还可当作实义动词使用，这时 need 就象其他动词一样，有第三人称，单复数，后面加带 to 的动词等特性。1.I need a bike to go to school.我上学需要一辆自行车。2.Do you need a dictionary? 你需要词典吗? 3.She needs a necklace.她需要一条项链。
needn't + have + 过去分词 表示过去做了没必要做的事情。You needn't have taken it seriously.这件事情你不必太认真。
二、Dare表示“敢”，Dare作情态动词时，主要用于疑问句、否定句和条件从句中，一般不用在肯定句中。多用在否定或疑问句中。1.The little girl dare not speak in public.小女孩不敢在公众面前说话。2.Dare you catch the little cat? 你敢抓小猫吗? dare 除用作情态动词外，更多的是当实义动词使用，用法同实义动词一样，要考虑人称，单复数，时态等。
1.Do you dare to walk in the dark? 你敢黑夜走路吗？
2.He doesn't dare to tell the teacher what happened that day.他不敢告诉老师那天发生的事。
三、Dare和need常用作实义动词，有时态、人称和数的变化，所不同的是，作实义动词时，在肯定句中，dare后面通常接带to的不定式，在否定和疑问句中，dare后面可接带to或不带to的不定式。如：
I dare to swim across this river.He does not dare(to)answer.Don't you dare(to)touch it!I wondered he dare(to)say that.He needs to finish it this evening.另外need 的被动含义：need，want，require，worth（形容词）后面接doing，也 可以表示被动：need doing=need to be done Shall用于第一人称,表示征求对方的意愿.如：What shall we do this evening? 2.Shall用于第一、第三人称疑问句中,表示说话人征求对方的意见或向对方请示.如：Shall we begin our lesson? When shall he be able to leave the hospital? 3.Shall用于第二、第三人称,表示说话人给对方命令、警告、允诺或威胁.如：You shall fail if you don't work harder.（警告）He shall have the book when I finish reading.（允诺）He shall be punished.（威胁）
