TeachingProcedures:
Step1.Checktheanswerstoexercise1onP21.
Step2.ReviewModalVerbs.
1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。
2比较can和beableto
1）can/could表示能力；可能（过去时用could）,只用于现在式和过去式（could）。beableto可以用于各种时态。例如：
Theywillbeabletotellyouthenewssoon.他很快就能告诉你消息了。
2）只用beableto的情况：
a.位于助动词后。b.情态动词后。c.表示过去某时刻动作时。d.用于句首表示条件。
e.表示成功地做了某事时，用was/wereableto，不能用could。例如：
HewasabletofleeEuropebeforethewarbrokeout.=HemanagedtofleeEuropebeforethewarbrokeout.
注意：could有时不表示时态
1）提出委婉的请求，（注意在回答中不可用could）。例如：
---CouldIhavethetelevisionon?我能看电视吗？
---Yes,youcan./No,youcant.可以/不可以。
2）在否定句、疑问句中表示推测或怀疑。例如：
Hecouldntbeabadman.他不大可能是坏人。　
3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。例如：
MayGodblessyou!愿上帝保佑你！
Hemightbeathome.他可能在家。
注意：might表示推测时，不表示时态，只是可能性比may小。
2）成语：may/mightaswell，后面接不带to的不定式，意为"不妨"。例如：
Ifthatisthecase,wemayaswelltry.如果情况确实如此，我们不妨试一试。
典型例题
Peter___comewithustonight,butheisntverysureyet.
A.mustB.mayC.canD.will
答案B.表可能性只能用may。此句意可从后半句推出。
4比较haveto和must
1）两词都是必须的意思，haveto表示客观的需要，must表示说话人主观上的看法，既主观上的必要。例如：
Mybrotherwasveryill,soIhadtocallthedoctorinthemiddleofthenight.　
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）
Hesaidthattheymustworkhard.他说他们必须努力工作。（主观上要做这件事）
2）haveto有人称、数、时态的变化，而must只有一种形式。但must可用于间接引语中表示过去的必要或义务。例如：
Hehadtolookafterhissisteryesterday.他昨晚只得照顾他姐姐。
3）否定结构中：donthaveto表示"不必"，mustnt表示"禁止"。例如：
Youdonthavetotellhimaboutit.你不一定要把此事告诉他。
Youmustnttellhimaboutit.你不得把这件事告诉他。
5must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。例如：
Youhaveworkedhardallday.Youmustbetired.你辛苦干一整天，一定累了。（对现在情况的推测判断）
Hemustbeworkinginhisoffice.他一定在办公室工作呢。
比较：Hemustbestayingthere.他现在肯定在那里。
Hemuststaythere.他必须呆在那。
3）must表示对已发生的事情的推测时，must要接完成式。例如：
Ididnthearthephone.Imusthavebeenasleep.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。例如：
---Whydidntyouanswermyphonecall?为何不接我的电话？
---Well,Imusthavebeensleeping,soIdidnthearit.唉，肯定在睡觉，所以没有听见。
5）否定推测用cant。例如：
IfTomdidntleavehereuntilfiveoclock,hecantbehomeyet.
6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。例如：
Idontknowwheresheis,shemaybeinWuhan.我不知道她在哪儿，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。例如：
Atthismoment,ourteachermustbecorrectingourexampapers.这时，想必我们老师正在批改试卷。
3）情态动词+动词完成时，表示对过去情况的推测。例如：
Theroadiswet.Itmusthaverainedlastnight.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。例如：
Yourmothermusthavebeenlookingforyou.你妈妈一定一直在找你。
5）推测的否定形式，疑问形式用cant,couldnt表示。例如：
Mikecanthavefoundhiscar,forhecametoworkbybusthismorning.
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。
7情态动词+have+过去分词
1）may（might）have+donesth,can（could）have+donesth表示过去，推测过去时间里可能发生的事情。例如：
Philipmay（might）havebeenhurtseriouslyinthecaraccident.菲力浦可能在车祸中受了重伤。
Philipcan（could）havebeenhurtseriouslyinthecaraccident.
2）musthave+donesth，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。例如：
---Lindahasgonetowork,butherbicycleisstillhere.琳达已经去上班了，但她的单车还在这儿。
---Shemusthavegonebybus.肯定乘巴士去的。
3）oughttohavedonesth,shouldhavedonesth表示本应该做某事，而事实上并没有做。否定句表示"不该做某事而做了"。例如：
Yououghtto（should）havebeenmorecarefulinthisexperiment.你当时在做试验时应该更仔细点。
Heoughtnottohavethrowntheoldclothesaway.他不该把旧衣服扔了。（事实上已扔了。）
oughtto在语气上比should要强。
4）neednthavedonesth表示本没必要做某事，但做了。例如：
Idressedverywarmlyforthetrip,butIneednthavedoneso.Theweatherwashot.
旅行时，我衣服穿得较多，其实没有必要。那时天很热。
5）wouldliketohavedonesth表示本打算做某事，但没做。例如：　
Iwouldliketohavereadthearticle,butIwasverybusythen.我想读这篇文章，但太忙了一直没读。
8.should和oughtto
除了上述的用法，两者还可表示"想必一定，按理应该"的意思。例如：
Ioughttobeabletoliveonmysalary.靠我的薪水，想必也能维持了。
Itoughttobereadynow.想必现在准备好了吧。
Theyshouldbetherebynow,Ithink.现在他们该到那儿了。
Thepoemsshouldbeoutinamonthatmost.诗集估计最多还有一个月就要出版了。
9hadbetter表示"最好"，相当于一个助动词，它只有一种形式，它后面要跟动词原形。例如：
Itisprettycold.Youdbetterputonmycoat.天相当冷。你最好穿上我的外套。
Shedbetternotplaywiththedog.她最好不要玩耍那条狗。
hadbetterhavedonesth表示与事实相反的结果，意为"本来最好"。例如：
Youhadbetterhavecomeearlier.你本该来得早一点。
10wouldrather表示"宁愿"
wouldratherdo
wouldrathernotdo
wouldrather…than…宁愿…而不愿。
还有wouldsooner,hadrather,hadsooner都表示"宁愿"、"宁可"的意思。例如：
IfIhaveachoice,Ihadsoonernotcontinuemystudiesatthisschool.
Iwouldratherstayherethangohome.=Iwouldstayhereratherthangohome.
典型例题
----Shallwegoskatingorstayathome?
----Which___do?
A.doyouratherB.wouldyouratherC.willyouratherD.shouldyourather
答案B。本题考查情态动词rather的用法，wouldrather+dosth意为"宁愿"，本题为疑问句，would提前，所以选B。
11will和would
注意：1）wouldlike；wouldliketodo=wantto想要，为固定搭配。例如：
Wouldyouliketogowithme?想和我一块去吗？
2）Willyou…?　Wouldyoulike…?表示肯定含义的请求劝说时，疑问句中一般用some,而不是any。例如：
Wouldyoulikesomecake?吃点蛋糕吧。
3）否定结构中用will，一般不用would,wontyou是一种委婉语气。
Wontyousitdown?你不坐下吗？
12情态动词的回答方式
问句肯定回答否定回答
Needyou…?Yes,Imust.No,Ineednt
Mustyou…?No,Idonthaveto.
典型例题
1）---CouldIborrowyourdictionary?
---Yes,ofcourse,you____.
A.mightB.willC.canD.should
答案C.could表示委婉的语气，并不为时态。答语中ofcourse，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。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）---ShallItellJohnaboutit?
---No,you___.Ivetoldhimalready.
A.needntB.wouldntC.mustntD.shouldnt
答案A。neednt不必，不用。wouldnt将不,不会的。mustnt禁止、不能。shouldnt　不应该。本题为不需要，不必的意思，应用neednt。
3）---Dontforgettocometomybirthdaypartytomorrow.
---______.
A.IdontB.IwontC.IcantD.Ihavent
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。
13带to的情态动词
带to的情态动词有四个：oughtto,haveto,usedto,beto,如加上havegotto（=must）,beableto，为六个。它们的疑问、否定形式应予以注意：
Dotheyhavetopaytheirbillbeforetheendofthemonth?
Shedidntusetoplaytennisbeforeshewasfourteen.
Yououghtnottohavetoldherallaboutit.
Oughthetoseeaheartspecialistatonce.?
oughtto本身作为情态动词使用。其他的词作为实义动词使用，变疑问，否定时，须有do等助动词协助。
典型例题
Tomoughtnotto___meyoursecret,buthemeantnoharm.
A.havetoldB.tellC.betellingD.havingtold
答案A。由于后句为过去时，告诉秘密的动作又发生在其前因，此地应用过去完成时，但它在情态动词oughtto后，所以用havetold。
14比较need和dare
这两词既可做实义动词用，又可做情态动词用。作为情态动词，两者都只能用于疑问句，否定句和条件句。need作实义动词时后面的不定式必须带to，而dare作实义动词用时,后面的to时常可以被省略。
1）实义动词：need（需要,要求）need+n./todosth
2）情态动词：need，只用原形need后加do，否定形式为neednot。例如：
Needyougoyet?你要走了吗？
Yes,Imust./No,Ineednt.是的，我要走了/不，不急着走。
