形容词比较级最高级专题练习

新目标八年级英语形容词比较级最高级专题练习形容词和副词比较级、最高级(一)1.形容词，副词比较级和最高级的概念。形容词和副词可以靠改变形式来表示程度的不同。我们把这种变化形式叫做比较等级。要比较两个或两个以上的人或物时，就必须用形容词的比较级和最高级。形容词、副词有三个级：原级(PositiveDegree)，比较级(ComparativeDegree)和最高级(SuperlativeDegree)。2.形容词比较级和最高级的构成。①单音节和少数双音节形容词、副词的规则变化情况：a.在原级的词尾加-er变为比较级，加-est变为最高级。e.g.short(原级)---shorter(比较级)---shortest(最高级)long(原级)---longer(比较级)---longest(最高级)b.如原级以e结尾，则比较级只加-r，最高级只加-st。e.g.large---larger---largestnice---nicer---nicestc.如原级以“辅音字母+y”结尾，要将y改为i，再加-er，-est。e.g.busy---busier---busiesteasy---easier---easiestd.原级以重读闭音节结尾，而且末尾只有一个辅音字母(不含字母组合er等)，要双写这个辅音字母，再加-er，-est。e.g.fat---fatter---fattestbig---bigger---biggest②大多数双音节和多音节形容词、副词的规则变化，是在原级前加more变成比较级，加most变成最高级。e.g.beautiful(原级)---morebeautiful(比较级)---mostbeautiful(最高级)interesting(原级)---moreinteresting(比较级)---mostinteresting(最高级)③有少数形容词,副词的比较级和最高级是不规则的。这些单词的变法需要大家识记。e.g.good---better---bestbadworseworstillmanymoremostlittle---less---leastmuchfartherfarthestolderoldestfaroldfurtherfurthesteldereldest④要注意有几个形容词的比较级和最高级有两种不同的形式，它们的意思也不同。e.g.old---older较旧，较老---oldest最旧，最老/old---elder较年长---eldest最年长far---farther较远---farthest最远(指距离)/far---further进一步---furthest最深(指程度)3.形容词比较级的用法和相关句型。①表示两者“相等”用“as+形容词原级+as+比较对象”。e.g.Heisastallashismother．Englishisasinterestingasmath.②表示“不如”或“不相等”用“not+as／so+形容词原级+as+比较对象”。e.g.Itisnotso／ascoldtodayasyesterday．Jackisnotso/astallasTom.③表示倍数，如“一半／两倍/3倍／4倍／……”等用“half／twice／three／four／…times+as…as…”结构。e.g.Istudytwiceashardasyou．Thisroomisthreetimesaslargeasthatone.④用“形容词比较级+than引导的从句”进行两者的比较。e.g.Theearthisbiggerthanthemoon．Thisdressismoreexpensivethanthatone.⑤强调比较级超出比较程度时，形容词的比较级前可用much，far，alot，still，no，alittle，even，any,等状语来修饰。e.g.MybrotherismucholderthanI.Thisbikeisfarbetterthanthatone.⑥由and连接同一个形容词的两个比较级，可以表示“越来越……”。e.g.I’mgettingfatterandfatter．IthinkEnglishisbecomingmoreandmoredifficult.⑦用“the+比较级…+the+比较级…”，表示“越……就越……”。e.g.Themoreyouread，themoreknowledgeyouwillget．Thelessjunkfoodyoueat,thehealthieryoufeel.一写出下列形容词的比较级和最高级形式1.small2.high3.nice4.wide5.heavy6.early7.hot8.big9.low10.slowly11.expensive12.difficult13.many/much14.old15.little16.far17.good/well18.bad/badly19.beautiful20.clever21.awful22.cheap23.clean24.cold25.colorful26.cool27.crowded28.dangerous29.delicious30.dirty31.fantastic32.friendly33.hard34.hungry35.late36.lazy37.quiet38.smart39.tall40.thin41.ugly43.few二用所给词的适当形式填空。1.Maryis,butJaneis.JaneisthanMary.Carolineisvery.Sheistheintheclass.(tall)2.Jane’shandwritingis,butMary’sis.Caroline’shandwritingisvery.ItisthehandwritingIhaveeverseen.(bad)3.Thethreegirlshavephotosoffilmstars.Maryhasn’tphotos,butJanehas.JanehasphotosthanMary.Carolinehasthephotosofthethree.(many)4.Mary’sChineseisnotvery.Jane’sis.Caroline’sChineseisthe.(good)5.Lastweekthethreegirlsboughtdresses.Caroline’sdresswasthanJane’s.ButMary’sdresswasthe.(expensive)6.Maryworksinahospital.Sheis.Janeworksinaschool.SheisthanMary.Carolineworksinacompany.Shealwaysworksdayandnight.Sheistheofall.(busy)7.Jane’sbedroomisvery.Caroline’sbedroomisthanJane’s.Mary’sistheofthethree.(large)8.Caroline’smotherisvery.Jane’smotheristhanCaroline’s.ButMary’smotheristheofthethreemothers.(fat)9.Janehaswaterinthebottle.MaryhasthanJane.Carolinehastheofall.(little)10.Theearthis,thesunisthantheearth.Buttheuniverseisthe.(big)11.Bobis_(young)thanFredbut_(tall)thanFred.12.Tomisnotas_(tall)asJack.13.Almostallthestudents’facesarethesamebutLiDeminglooks_(fat)thanbeforetheholidays.14.Whichis_(heavy),thisboxorthatone?15.--How_(tall)isSally?--She’s1.55meters_(tall).WhataboutXiaoling?--She’sonly1.40meters_(tall).Sheismuch_(short)thanSally.Sheisalsothe_(short)girlintheclass.16.Heis_(bad)atlearningmath.Heismuch_(bad)atChineseandheisthe_________(bad)atEnglish.17.AnniesaysSallyisthe_(kind)personintheworld.18.Heisoneofthe_(friendly)peopleintheclass,Ithink.19.Adictionaryismuch_________(expensive)thanastory-book.20.Anorangeisalittle_(big)thananapple,butmuch________(small)thanawatermelon.21.TheChangjiangRiveristhe_(long)riverinChina.22.Sueisalittle________(beautiful)thanhersister.23.Myroomisnotas_________(big)asmybrother’s.24.--Howdifficultisphysics?--I'mnotsure.--Isit________(difficult)thanmath?--Idon’tthinkso.25.--Annieplaysthepianovery_(well).--Sueplaysit_(well)thanAnnie.AndSallyplaysitthe_(well).26.Saturdayismy(busy)dayinaweek.27.Hermotherisgetting(fat)and________(fat).28.Ithinkit’stooexpensive.I’dlikea_(cheap)one29.Hecomestoschoolmuch_(early)thanI.30.Thisbookisnotas_(interesting)asthatone.31.Yourclassroomis_(wide)and_(bright)thanours.32.Practiceas_(much)asyoucan.33.The_(much),the(good).34.NowadaysEnglishis(important)thananyothersubject,1think.35.Mostofthestudentsthinkalionismuch________(dangerous)thanabearanditisthe__________(dangerous)animalintheworld.三单项选择。1.--Sheis______thanhermother.--Hermotherisalsobeautiful.A.beautifulB.beautifulerC.morebeautifulD.mostbeautiful2.--Ourschoolistheirs.--Whatabigone!A.asfivebigasB.asfivetimesbigasC.asbigasfivetimesD.fivetimesasbigas3.--Doyoualwaysgetupasasyoubrother?--Notalways.A.earliestB.earlierC.theearliestD.early4.--Theearthis______themoon.--Ialsosawitonthenewspaper.
