(3)最高级前可加序数词。eg.TheYellowRiveristhesecondlongestriverinChina.(4)形容最高级修饰作表语或介词宾语的名词，代词时，被修饰的词往往省略。eg.Heisthelaziest(student)inourclass.(5)形容最高级用在选择疑问句中，结构为：Who/Which...,A,BorC?WhoisthebestEnglishteacher,Mr.Zhang,MissLiorMissWang？ 2.形容词比较级和最高级的构成规则变化一般情况下，单音节或双音节的形容词比较级直接加-er,最高级直接加-est。如：clever—cleverer—cleverestcheap—cheaper—cheapestfew—fewer—fewestsmall—smaller—smallestyoung—younger—youngest b.以-e结尾的形容词，比较级+-r,最高级+-st。如：large—larger—largestnice—nicer—nicestcute—cuter—cutestc.以辅音字母+y结尾的形容词，变y为i+er或+estbusy—busier—busiestheavy—heavier—heaviesteasy—easier—easiesthappy—happier—happiestdirty—dirtier—dirtiest d.以重读闭音节结尾，末尾只有一个辅音字母结尾的词，双写最后一个辅音字母，再加+er或+est。如：big—bigger—biggestthin—thinner—thinnestfat—fatter—fattesthot—hotter—hotteste.多音节和部分双音节形容词，需在原级前+more构成比较级，+most构成最高级。important—moreimportant—mostimportantbeautiful—morebeautiful–mostbeautifuldifficult—moredifficult—mostdifficult 3.不规则变化：原级比较级最高级good/wellbetterbestbad/ill/badlyworseworstlittlelessleastmany/muchmoremostfarfarther/furtherfarthest/furthestoldolder/elderoldest/eldest 最高级规则变化口诀：最高级，很容易，一般词尾加est。(cheap-thecheapest)词尾若有哑音e，直接就加st。(close-theclosest)重读闭音节，单辅音字母要双写。(big-thebiggest)辅音字母加y，记得把y变为i。(friendly-thefriendliest)多音节，考考你，themost到底加哪里？(popular-themostpopular) 复习：形容词最高级的构成A:tallshortquickthicklightcoolwarmquietwildcalm--estB:heavyeasytidydrybusyhappyhealthyhungryearlyy--i--est C:largelatenice--stbiggestD:bighothottestthin“双写”thinnestwetwettestfatfattest 1.WearegoingtotheGreenRestaurantforlunch.(划线部分提问)____________yougoingforlunch?2.Samistheshortestinhisclass.(改为同义句)Samis________than_________studentinhisclass.Samis_______than__________studentsinhisclass.Samis_______than______________inhisclass.3.HowdoyoulikeScreenCity?(改为同义句)_______doyou__________ScreenCity?WhereareshorteranyotherWhatthinkofshortertheotheranyoneelseshorter练习：改写句子。 Fillintheblankswiththecorrectformsofthewordsinbrackets.1.Wewenttothe_______(bad)restaurantintownlastnight.Themenuhadonly10dishesandtheservicewasnotgoodatall!2.BlueMoonis_______(good),butMiller’sis________(good)intown.3.TheBigScreenis__________________(expensive)thanmostcinemas,butCinemaCityis_____________________(expensive).worstgoodthebestmoreexpensivethemostexpensive3a 4.MovieCityhasthe________(bad)service,butwecansitthe____________________(comfortably)there.5.JohnnyDeppactedthe_____(good)inthatmovie.He’smuch_________(good)thanothersatfindingthe__________________(interesting)roles.worstmostcomfortablybestmostinterestingbetter Thinkofthreestoresinyourtownandfillinthechart.Thenwritesixsentencesusingtheinformationinthechart.Servicebest:worst:Qualitybest:worst:Pricescheapest:mostexpensive:A:IthinkGreatWorldhasthebestservice.B:IthinkCoolHousehastheworstquality.3b Wherearewegoingforlunch?Thinkofthreeplacestohavelunchnearyourschool.Writetheinformationinthechart.Thendecideonthebestplacetohavelunch.3c RestaurantsDanny’sHowmuchisameal?Howfarisitfromschool?10minutesbybusIstheservicegood?Isthefoodgood?A:Danny’sistheclosest.Let’sgothere.B:No,it’sthemostexpensive.Ithinkweshouldgoto… I.根据要求写出单词。1.bad(比较级）2.do(过去式）3.best(原级）4.expensive(反义词）5.big(最高级）6.report(名词）7.friend(形容词）8.beach（复数）9.quiet(反义词）10.store（同义词）worsedidgood/wellcheapbiggestreporterfriendlybeachesnoisyshopExercises 3.LinSenis_______________________intheclassbecausehenevergetstoschoolontime.（最懒的学生之一）4.Edisonwas_________________________intheworld.(最伟大的发明家之一）oneofthelazieststudentsoneofthegreatestinventorsTheYangtzeRiveris________________riverintheworld.(第三长河）thethirdlongest2.TheAtlanticis________________oceanintheworld.(第二大洋）thesecondbiggestII.翻译句子。 1.HainanisaverylargeIsland.Itisthesecond_________islandinChina.(large)2.Ourteacherisas______asbefore.(busy).3.Heis__________________amongus.(careful)4.LiLeijumpedfar______thanJim.(far)5.Thebusierheis,the________hefeels.(happy)6.IthinkYaoMingisoneof____________basketballplayersinNBA.(hot)busythemostcarefulfartherhappierlargestthehottestIII.完成句子。 LeBronJamesisoneof_______playersintheNBA.Heismyhero.betterB.thebestC.worseD.theworst中考链接由“他是我的英雄。”可知詹姆斯是最好的NBA队员之一。oneof后面加形容词的最高级。B —Whorunsinyourclass?—Tomdoes.Noneofuscancatchhimintherace.A.fasterB.slowerC.fastestD.slowest由“没人能赶得上他。”可知Tom跑得最快。要选择fast的最高级。C Homework1.Dosomeexercisebyusingcomparativeandsuperlativedegree.2.Writeacompositionaboutrestaurantsbyusingcomparativeandsuperlativedegreesofadjectivesandadverbs.
