dislike(不喜欢)情态动词（Modalverbs）1.定义：本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。2.用法：情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想。情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加"not"。3.分类：情态动词虽然数量不多，但用途广泛，主要有下列：can(could),may(might),must,need,oughtto,dare(dared),shall(should),will(would)mustnot.【专题一】:can和could的用法【例1】Canyouliftthisheavybox?(体力)【解析】表示能力(体力、知识、技能)【练习】 1.Mary___________speakthreelanguages.(知识) 2.___________youskate?(技能) 此时可用beableto代替。Can只有一般现在时和一般过去式;而beableto则有更多的时态。 I’llnotbeabletoethisafternoon. 当表示“经过努力才得以做成功某事”时应用beableto,不能用Can。【例2】 CanIgonow? Yes,youcan./No,youcan’t.【解析】表示请求和允许。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。【练习】 ___________Ietoseeyoutomorrow? Yes,you___________. No,you___________/I’mafraidnot.【例3】Canthisbetrue?【解析】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。【练习】 This___________bedonebyhim. How___________thisbetrue?【专题二】may和might的用法：【例1】Might/MayIsmokeinthisroom? No,youmustn’t.【解析】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”。用MayI...?征徇对方许可时比较正式和客气,而用CanI...?在口语中更常见。【练习】 ___________Itakethisbookoutoftheroom? Yes,you___________.No,you【例2】Hemay/mightbeverybusynow.【解析】表示推测、可能性(不用于疑问句)。might非过去式,它所表示的可能性比may小。【练习】 1.Yourmother___________notknowthetruth. 2.He___________verybusynow.他现在可能很忙。【专题三】must和haveto的用法：【例1】Theman___________beourteacher。那个人一定是我们的老师。【例2】I___________studyhardbecauseofmydream.为了我的梦想我必须努力学习。【例3】1.You___________eintime.你必须准时过来【解析】：must表示必须、必要。表示主观对事物的推测时，意为想必、一定，只用于肯定句中;表推测时，情态动词与动词原形(常为be动词)连用。而haveto强调客观需要。【练习】: 1.Herplayisboring,I___________gonow. 2.Yourmother___________bewaitingforyounow. 3.I___________gohome,becausemyfatherisill.【例4】Mustwehandinourexercisebookstoday?Yes,you___________.No,you___________.【解析】：在回答由must引出的问句时，如果是否定的，不能用mustn’t,而用needn’t,don’thaveto.must是说话人的主观看法,而haveto则强调客观需要。【练习】: Musthegotoschoolnow? Yes,he___________. No,he___________.【专题四】should的用法【例1】Ishouldhelpherbecausesheisintrouble.【解析】should表示应该【练习】 You___________takecareofthebaby.【例2】Youshouldgotoclassrightaway.【解析】表示劝告、建议和命令。在疑问句中常用should。【练习】___________Iopenthewindow？【专题五】will和would的用法【例1】Iwilldoanythingforyou.【解析】表示询问，请求,将要。【练习】 1.___________youpassmethebook? 2.She___________gotothelibrary.【例2】Wouldyoutellmethewaytotheschool?【解析】表示过去的意愿或委婉提问一、用适当的情态动词填空。1.MustIborrowthebookwithmyIDcard?No,you___________.2.___________Iuseyourcar?Yes,you___________.3.___________Igohomenow?No,you___________stayhereandwaitfortheteacher.4.Mymotherisill.I___________stayathomeandlookafterher.5.I___________sendanemailtomyfriend.6.You___________takemoreexercise.7.___________youtellmehowtogettothePark?8.We___________helpeachother.9.___________youliketogofishingwithme?10.___________weplayfootballthisafternoon?二、按要求改写句子。1.Icanrunfast.(否定句)I______________________fast.2.Youmustreturnthebooknow.(一般疑问句)___________Ireturnthebooknow?No,you___________.3.Hecanplaybasketballwell.(一般疑问句)___________He___________basketballwell?4.Theymusttakethebooksoutoftheroom.(否定句)They______________________thebooksoutoftheroom.5.Hewillgetupearly.(否定句）He______________________getupearly.三、选择题()1.Lucyshould___________herhomeworknow.
