初中英语形容词、副词比较级和最高级绝大多数形容词有三种形式,原级,比较级和最高级,以表示形容词说明的性质在程度上的不同。形容词的原级:形容词的原级形式就是词典中出现的形容词的原形。例如:poortallgreatgladbad形容词的比较级和最高级:形容词的比较级和最高级形式是在形容词的原级形式的基础上变化的。分为规则变化和不规则变化。规则变化如下:1)单音节形容词的比较级和最高级形式是在词尾加-er和-est构成。great(原级)(比较级)(最高级)2)以-e结尾的单音节形容词的比较级和最高级是在词尾加-r和-st构成。wide(原级)(比较级)(最高级)3)少数以-y,-er,-ow,-ble结尾的双音节形容词的比较级和最高级是在词尾加-er和-est构成。clever(原级)(比较级)(最高级)4)以-y结尾,但-y前是辅音字母的形容词的比较级和最高级是把-y去掉,加上-ier和-est构成.happy(原形)(比较级)(最高级)5)以一个辅音字母结尾其前面的元音字母发短元音的形容词的比较级和最高级是双写该辅音字母然后再加-er和-est。big(原级)(比较级)(最高级)6)双音节和多音节形容词的比较级和最高级需用more和most加在形容词前面来构成。beautiful(原级)(比较级)(比较级)difficult(原级)(最高级)(最高级)常用的不规则变化的形容词的比较级和最高级:原级比较级最高级goodbetterbestmanymoremostmuchmoremostbadworseworestlittlelessleastillworseworestfarfartherfarthest形容词前如加less和least则表示较不和最不important重要lessimportant较不重要leastimportant最不重要形容词比较级的用法:形容词的比较级用于两个人或事物的比较,其结构形式如下:主语+谓语(系动词)+形容词比较级+than+对比成分。也就是,含有形容词比较级的主句+than+从句。注意从句常常省去意义上和主句相同的部分,而只剩下对比的成分。Ourteacherisweare.我们老师的个子比我们的高。Itistodaythanitwasyesterday.今天的天气比昨天暖和。Thispictureisthanthatone.这张照片比那张照片漂亮。Thismeetingisthanthatone.这次会议不如那次会议重要。Thesunisthanthemoon.太阳比月亮大得多。形容词最高级的用法:形容词最高级用于两个以上的人和物进行比较,其结构形式为:主语+谓语(系动词)+the+形容词最高级+名词+表示范围的短语或从句。Sheisstudentherclass.她是班上最好的学生。ShanghaiisoneofcitiesChina.上海是中国最大城市之一。ThisisappleIhaveevermet.这是我见到的最大的苹果。Tomisboyinhisbasketballteam.汤姆是他们篮球队中个子最高的孩子。形容词/副词原级比较基本用法原级比较由“as+形容词或副词(或再加名词或短语)+as”构成“原级相同”比较句,表示两者比较;其否定式,即“程度不及”比较句型为“notso(as)+形容词或副词+as”,而且as…as结构前可用just,almost,nearly,quite等表示程度的词修饰一.形容词或副词的原级、比较级和最高级的测试1.用括号中形容词或副词的适当形式填空1)Thisparkismuchthanthatone.(beautiful)2)I’maboyinthesun.(happy)3)Whichbookis,yoursormine?(thick)4)Mymotherdrivesasasmyfather.(good)5)WhoisthanI,heorshe?(old)2.不改变意思,改写下列句型1)Ilikechickenbetterthanfish.Ichickenfish.2)LinTaoisthetallestboyinhisclass.LinTaoisanyotherinhisclass.3)Scienceisnotsointerestingasmusic.Scienceisthanmusic.Musicisthanscience.4)Thisboxis12kg.Thatboxis14kg.Thisboxisthatone.Thatboxisthisone.5)Maryis10yearsold.Lilyis12yearsold.MaryisLily.LilyisthanMary.3.选择填空()1.Thisbookisthatone.A.notsointerestingB.moreinterestingthanC.asmoreinterestingasD.interestingthan()2.IthinkmathsisnotEnglish.A.easierB.lesseasyC.easyD.soeasyas()3.Heisoneofinourcountry.A.themostpopularsingerB.themostpopularsingersC.themorepopularsingersD.mostpopularsingers()4.-Whichdoyouprefer,vegetablesorfruit?-Ipreferfruitvegetables.A.toB.thanC.ofD.and()5.TheweatherinBeijingisasinShanghaitoday.A.wetterthantheweatherB.wetastheweatherC.wetthanthatD.wetasthat、二.注意几个词组1.asgoodas几乎已经,实际上等于,和……几乎一样Heisasgoodasdead.他跟死了一样。Thesecondhandgeographybookisasgoodasnew.这本二手地理书几乎还是新的。2.assoonas一……就……PleaseletusknowassoonasyouarriveinBeijing.一到北京,请通知我们一声。Assoonasshegothome,shebegancooking.她一到家就开始做饭。3.asmuch/manyas多达……,达到……之多,实际上等于,差不多Someofthestonesevenweighasmuchasfifteentons.有些石块甚至重达15吨。Thenumberofpeoplewholosthomesreachesasmanyas250,000.失去家园的人数多达25万。That”sasmuchastosayhewasathief.那无异于说他曾是个小偷。4.asfaras就……而言,尽……AsfarasIknow,he”llbeawayforthreemonths.就我所知,他将离开三个月。Wewillhelpyouasfaraswecan.我们会尽力帮助你。5.aslongas只要Youcangowhereyoulikeaslongasyougetbackbeforedark.你去哪儿都可以,只要你在天黑前返回。YouwillbehappyaslongasIamliving.只要我活着,你就会幸福。6.asoftenas每当,每次Asoftenashecame,hewouldstaywithusforatime.每次他来,总要和我们呆上一阵子。TheboyalwayssayshellotomeasoftenasImeethim.每次我遇见那个小男孩,他总是向我问好。7.aswellas和,同,既……又……,不仅……而且……Myparentsaswellasmyelderbrotherenjoymusic.我父母亲和我哥哥都喜欢音乐。Heiscleveraswellashardworking.他不仅努力工作而且聪明。8.as…aspossible/onecan尽可能,尽(某人)所能Pleasesweepthefloorascleanaspossible.请把地打扫得尽可能干净。I”llgetbackassoonasIcan.9.“比较级+and+比较级”表示“越来越……”。如:Hebecomesand.(越来越胖)10.The+比较级…,the+比较级”表示“越……,越……”。如:Theheis,thehefeels.他越忙就越高兴。三.(1)表示倍数有...timesas+形容词原级+as的句型。如:Thisgardenisasasthatone.(三倍大)Thisroomisasasthatone.(两倍大)(2)halfas+形容词原级+as表示“……的一半”。如:Thisbookishalfasthickasthatone.巩固练习:1.Thisboxis___thatone.A.heavythanB.soheavythanC.heavierasD.asheavyas2Whenwespeaktopeople,weshouldbe'.A.aspoliteaspossibleB.aspoliteaspossiblyC.aspolitelyaspossibleD.aspolitelyaspossibly3Thisbookis____thatone,but____thanthatone.A.asdifficultas;expensiveB.asmoredifficultas;moreexpensiveC.asdifficultas;moreexpensiveD.moredifficultas;asexpensive4Ithinkthestoryisnotso___asthatone.A.interestingB.interestedC.moreinterestingD.mostinteresting5Hisfatherbegantowork____hewassevenyearsold.A.asoldasB.asearlyasC.sinceD.while21.Ithinkscienceis_thanJapanese.A.muchimportantB.importantC.muchmoreimportantD.moremuchimportant()2Thispencilis___thanthatone.^.longestB.longC.longerD.aslong()3Mymotherisno___young.A.shorterB.longerC.littleD.few()4Thesechildrenare____thisyearthantheywerelastyear.A.moretallB.moretallerC.verytallerD.muchtaller()5Itwasveryhotyesterday,butitis___today.A.evenhotterB.morehotterC.muchmorehotD.muchhot6.MrsBlackhasgot____insteadofgettinganybetter.A.morebadB.alittleworseC.muchbadlyD.alotofworse3()1Whenwearrived,wefoundthemeetingroomcrowdedwith___students.A.quiteafewB.onlyafewC.fewD.afewquite2Thehouseissmallforafamilyofsix.A.muchtooB.toomuchC.verymuchD.so3Throughthewindowwecanseenothingbut____buildings.A.tallverymanyB.verymanytallC.verytallmanyD.manyverytall4-W
