八年级形容词副词比较级专练.doc

形容词和副词一般有三个等级,即原级、比较级和最高级.一比较级1. 表示两者的比较时用比较级,通常用“形容词/ 副词比较级+than”的结构 在含有连词than的比较级中,前后的比较对象必须是同一范畴,即同类事物之间的比较. 在比较级前面使用much, a bit, a little,. far, a lot，still, even等2“比较级 + and + 比较级”或“more and more +原级”表示“越来越3在含有or的选择疑问句中,如果有两者供选择,前面的形容词要用比较级形式.如：Who is taller,Tim or Tom? 谁更高,Tim还是Tom?4. “the +比较级, the+比较级”,表示“越越”.The more money you make, the more you spend.5. 表示倍数的比较级用法：. A is times the size /height/length/width of B.如：The new building is three times the height of the old one. A is times as big /high/long/wide/large as B.如：Asia is four times as large as Europe. A is times larger /higher/longer/wider than B.如：Our school is twice bigger than yours.6.当比较的双方属于同一范围内时候,用other或者else排除自己,因为自己不能和自己比较.例如：Shanghai is bigger than any other city in China. 上海比中国其他的城市大.如果比较的双方不属于同一范围内时候,则不存在和自己比较的情况,所以可以不用other或者else.例如：Shanghai is bigger than any city in Heilongjiang. 上海比黑龙江的任何城市都大.二 最高级1.形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较,表示“最”的意思.句子中有表示范围的词或短语.如：of the three, in our class等等.2.”在含有or的选择疑问句中,如果有三者供选择,前面的形容词要用最高级形式.3.one of the +最高级+复数名词” 表示“是最之一者4.the +序数词+最高级+名词单数三、原级的用法：一般来说,表示两者同等或不同等程度时用原级,通常用“as + 形容词/ 副词原级 + as .”或“not as （so）+ 形容词/ 副词原级 + as .”的结构. 1.只能修饰原级的词，very，quite，so，too。例如：He is too tired to walk on.他太累了以至于不能再继续走了。My brother runs so fast that I cant follow him.我弟弟跑得那么快以至于我跟不上他。2.原级常用的句型结构(1)“甲+实意动词+(倍数)+as+副词原级+as+乙”表示“甲和乙程度相同”或“甲是乙的几倍”。例如：Tom runs as fast as Mike.汤姆和迈克跑得一样快。Tom runs twice as fast as Mike.汤姆跑得速度是迈克的二倍。(2)“甲+助动词+not+动词原形+as/so+副词原级+as+乙”甲不如乙例如：He doesnt walk as slowly as you.他走路不像你那样慢A部分I用适当形式填空：1.Bobis_(young)thanFredbut_(tall)thanFred.2.YingTianisnotas_(tall)asYongXian.3.AlmostallthestudentsfacesarethesamebutLiDeminglooks_(fat)thanbeforetheholidays,4.Whichis_(heavy),ahenorachicken?5.-How_(tall)isSally?-Shes1.55metres_(tall).WhataboutXiaoling?Shesonly1.40metres_(tall).Sheismuch_(short)thanSally.Sheisalsothe_(short)girlintheclass.6.Heis_(bad)atlearningmaths.Heismuch_(bad)atChineseandheisthe_(bad)atEnglish.7.AnniesaysSallyisthe_(kind)personintheworld.8.Heisoneofthe_(friendly)peopleintheclass,Ithink.9.Adictionaryismuch_(expensive)thanastory-book.10.Anorangeisalittle_(big)thananapple,butmuch_(small)thanawatermelon.11.TheChangjiangRiveristhe_(long)riverinChina.12.Sueisalittle_(beautiful)thanhersister.13.Myroomisnotas_(big)asmybrothers.14.-Howdifficultisphysics?-Imnotsure.-Isit_(difficult)thanmaths?-Idontthinkso.15.Annieplaysthepianovery_(well).Sueplaysit_(well)thanAnnie.AndSallyplaysitthe_(well).16.Saturdayismy_(busy)dayinaweek.17.Hermotherisgetting_(fat)and_(fat).18.Ithinkitstooexpensive.Idlikea_(cheap)one.19.Hecomestoschoolmuch_(early)thanI.20.Thisbookisnotas_(interesting)asthatone.21.Yourclassroomis_(wide)and_(bright)thanours.22.Practiseas_(much)asyoucan.23.The_(much),the_(good).24.NowadaysEnglishis_(important)thananyothersubject,1think.25.Mostofthestudentsthinkalionismuch_(dangerous)thanabearanditisthe_(dangerous)animalintheworld.III完成句子：1她看起来不如玛丽年轻。Shedoesntlook_Mary.2.杰克的父亲比母亲大一岁。Jacksfatheris_thanhermother.3.我们的教室比他们的明亮得多。Ourclassroomis_thantheirs.4.当心！这条路越来越危险。Lookout!Themadisbecoming_and_.5.你喜欢哪种动物，猫还是狗？Whichanimaldoyoulike_,acatoradog?单项选择1.Thisboxis_thatone.A.heavythanB.soheavythanC.heavierasD.asheavyas2.Whenwespeaktopeople,weshouldbe_.A.aspoliteaspossibleB.aspoliteaspossiblyC.aspolitelyaspossibleD.aspolitelyaspossibly3.Thisbookis_thatone,but_thanthatone.A.asdifficultas;expensiveB.asmoredifficultas;moreexpensiveC.asdifficultas;moreexpensiveD.moredifficultas;asexpensive4.Ithinkthestoryisnotso_asthatone.A.interestingB.interestedC.moreinterestingD.mostinteresting5.Hisfatherbegantowork_hewassevenyearsold.A.asoldasB.asearlyasC.sinceD.while6.Ithinkscienceis_thanJapanese.A.muchimportantB.importantC.muchmoreimportantD.moremuchimportant7.Thispencilis_thanthatone.A.longestB.longC.longerD.aslong8.Mymotherisno_young.A.shorterB.longerC.littleD.few9.Thesechildrenare_thisyearthantheywerelastyear.A.moretallB.moretallerC.verytallerD.muchtaller10.Itwasveryhotyesterday,butitis_today.A.evenhotterB.morehotterC.muchmorehotD.muchhot11.Mrs.Blackhasgot_insteadofgettinganybetter.A.morebadB.alittleworseC.muchbadlyD.alotofworse12.Whenwearrived,wefoundthemeetingroomcrowdedwith_students.A.quiteafewB.onlyafewC.fewD.afewquite13.Thehouseis_smallforafamilyofsix.A.muchtooB.toomuchC.verymuchD.so14.Throughthewindowwecanseenothingbut_buildings.A.tallverymanyB.verymanytallC.verytallmanyD.manyverytall15.-Whatsyourbrotherlike?-Heis_.A.adriverB.verytallC.myfriendD.atschool16.Thejacketwasso_thathedecidedtobuyit.A.muchB.littleC.expensiveD.cheap17.Ourclassroomis_largerthantheirs.A.moreB.quiteC.veryD.much18.Theearthisabout_asthemoon.A.asfiftytimebigB.fiftytimesasbigC.asbigfiftytimesD.fiftyastimesbig19.Yourroomis_mine.A.twiceaslargethanB.twicethesizeofC.biggertwicethanD.astwicelargeas20.Yourroomis_thanmine.A.threetimebigB.threetimesbigC.threetimesbiggerD.biggerthreetimes21.Hisfatheris_thanhismother.A.olderfouryearsB.asfouryearsolderC.fouryearsolderD.biggerfouryears22.Mathsismorepopularthan_.A.anyothersubjectB.allthesubjectsC.anysubjectD.othersubject23.Chinaislargerthan_inAfrica.A.anyothercountryB.othercountriesC.theothercountryD.anycountry24.Tomisstrongerthan_inhisclass.A.anyotherboyB.anyboysC.anyboyD.otherboy25.Whenspringcomes,itgets_.A.warmandwarmB.colderandcolderC.warmerandwarmerD.shorterandshorter26.Byandby,_studentsinourclasscametolikeEnglish.A.moreandmoreB.muchandmuchC.manyandmanyD.lessandleast27.Atlasthebegantocry_.A.hardandhardB.morehardandmorehardC.harderandharderD.lesshardandlessharder28.Whenspringcomesthedaysget_andnights_.A.short;longB.long;shortC.longer;shorterD.shorter;longer29._Ilookatthepicture,_Ilikeit.A.Thebest;themoreB.Themore;thelessC.Themore;lessD.More;themore30._hereadthebook,_hegotinit.A.Themore;themoreinterestingB.Theless;themoreinterestingC.Themore;themoreinterestedD.More;moreinterested31._youcomeback,_itwillbe.A.Thequicker;thebestB.Thesooner;thebetterC.Faster;thebetterD.Thesooner;better32.Ilike_oneofthetwobooks.A.theolderB.oldestC.theoldestD.older33.Whichis_country,ChinaorJapan?A.thelargeB.thelargerC.largerD.largest34.Ofthetwocups,hebought_.A.thesmallerB.thesmallestC.smallD:smaller35.Whichdoyoulike_,teaorcoffee?A.wellB.betterC.bestD.most36.Thisworkis_formethanforyou.A.difficultB.mostdifficultC.muchdifficultD.moredifficult37.Whichdoyouthinktastes_,thechickenorthefish?A.goodB.betterC.bestD.well38.Thebookis_ofthetwo.A.thinnerB.thethinnerC.morethinnerD.thethinnestB部分二.选择1.-Whichis_season
