构成法 原级 比较级 最高级 一般加er,est long cold longer colder longest ccoldest 以结尾的词,只加r,st nice large nicer larger nicest largest 以一个辅音字母结尾,前面的元音读短音时,要双写结尾的辅音字母,再加er,est big fat bigger fatter biggest fattest 以辅音字母加结尾的词,改y为i,再加er,esteasy busy easier busier easiest busiest部分双音节词和多音节词,在前面加或来构成比较级和最高级:原级比较级最高级slowlymoreslowlymostslowlybeautifulmorebeautifulmostbeautiful(2)不规则变化如下表:原级比较级最高级good,wellbetterbestbad,illworseworstmany,muchmoremostlittlelessleastfarfarther,furtherfarthest,farthestoldolder,elderoldest,eldestii。形容词和副词比较等级的用法:(1)表示两者之间的比较时,用形容词比较级than句型。thesunisbiggerthantheearth。(2)表示两者以上的比较时,用the形容词最高级(名词)of(in)的句型。mybrotheristhetallestinhisclass。(3)表示两者是同等程度,用as形容词原级副词as句型,意思是和一样。表示两者不同程度时,用notso(as)形容词原级副词as的句型,意思是不如。它可与比较级互换。thisbookasgoodasthatone。lipingisnotasoldasweifang。swimmingisnotasinterestingasfishing。fishingismoreinterestingthanswimming。试分析下列练习:1。mycoatisthanyours。a。expensiveb。moreexpensivec。muchmoreexpensived。muchexpensive2。shanghaiisoneofcitiesinourcountry。a。largeb。largerc。largestd。thelargest3。whichsubjectis,mathorenglish?a。easyb。easierc。easyerd。easiest4。ofallthestudentsinourclass,bettywrite。a。verycarefulb。themostcarefulc。themostcarefullyd。morecarefully5。jackdoesn’tjumpsoashisbrother。a。highb。higherc。highestd。morehigh6。itwascoldyesterday。a。terribleb。terriblymoreterribled。mostterrible(4)常用的一些原级比较的结构还有:1。asmanymuchas意思为同数量的;一样多。hehasasmuchmoneyasjohn。youcansellasmanynewspapersasi。2。asmanylonghighas数字表示多达(长达、高达)。。ihavelearnedenglishforaslongas15yeaars。thebuildingcostsranuptoasmuchas20millionyuan。3。thesameasdifferentfromlike;当我们要表达某一事物与另一事物相同时,用aisthesameasb句型。当我们要表达某一事物和另一事物不同时,用aisdifferentfromb句型。当我们要表达某一事物与另一事物相像时,用aislikeb句型。mywatchisthesameasyours。tom’scoatisdifferentfromnick’s。mrwang’scarislikemyfather’s。这三个结构中所使用的动词多为be,但有时也用look,sound,taste,seem等系动词。thatgirllookslikehermother。thissongsoundsdifferentfromtheoneilike。thesameas也可分解为thesameas,same后面通常跟age,kind,length,colour,height,size,amount等名词。有时thesameas也可与asas互换使用。theruleristhesamelengthasthatone。thisrulerisaslongasthatone。试完成下面的练习:1。david和simon一样高。davidis(tall)。2。david的体重不如simon。davidis(heavy)。3。我的书不如你的书多。idon’thaveasyou。4。格林一家和怀特一家扔掉的垃圾一样多。thegreensthrowawayrubbishthewhites。5。这次事故中多大一百人丧生。100peoplewerekilledintheaccident。6。一天的费用可高达500元。thecostofonedaycanbe500yuan。7。这两姐妹看上去一样。thetwosisters。8。这条裙子与那一条不同。thisskirtisthatone。9。听起来像个好主意。thatagoodidea。10。两顶帽子一样。thetwohats。11。我和你年纪一样。iamyou。近年来在中考出现的对形容词和副词的比较等级的考查举例如下:考点一:对比较级的考查1。mikelooksthanpaul,buttheyarethesameage。a。youngestb。theyoungestc。youngerd。veryyoung形容词后面有than时,应该用形容词的比较级形式。应选c。2。intheexam,themorecarefulyouare,mistakesyouwillmake。a。thefewerb。thefewestc。thelessd。theleastthe比较级,the比较级是比较级的一个固定句型,表示越,就越。由此可排除b,d两项;又因为mistake是可数名词,不能用less修饰,所以选a。3。iloveshenzhenbecauseitisbecoming。a。moreandmorebeautifulb。beautifulandbeautifulc。cleanandcleand。moreandclean比较级and比较级也是比较级的一个固定句型,表示越来越;如果是多音节的形容词,则用moreandmore形容词原形所以选a。。考点二:考查比较级的修饰语4。pleasedon’tbeangrywithme,saidamylaughingly。thismakemeeven。a。angryb。angrierc。angriest根据题干的逻辑结构和程度副词even的使用,应填形容词的比较级形式,所以选b。比较级可以被表示程度的副词或短语修饰,这些表示程度的修饰语主要有even,still,far,much,alot,abit,alittle,any等。考点三:对形容词最高级的考查5。beijing,thecapitalofchina,isoneofcitiesintheworld。a。thebiggestb。biggerc。muchbiggerd。bigbeoneofthe形容词最高级名词(复数)范围是最高级的一个固定句型,意为是最之一,所以选a。用所给词的正确形式填空:who’s(tall),kittyormary?thechangjiangriverisoneofthe(long)riversintheworld。thechinesepeoplehaveamuch(good)lifenow。
