,形容词和副词的比较级和最高级,ComparativeandSuperlativeDegreesofAdjectivesandAdverbs,什么是形容词和副词？,形容词用于修饰名词，表示人或事物的属性或特征等。也就是形容名词的词,副词是用来说明动作或状态的特征,说明时间，地点，程度等概念。它用来修饰动词、形容词、副词、短语或句子。,形容词和副词的级别,大多数形容词和副词有三个等级：原级比较级最高级,形容词和副词比较等级的变化规律longlongerlongestnicenicernicestbigbiggerbiggestearlyearlierearliestinterestingmoreinterestingmostinterestingcarefullymorecarefullymostcarefullyfriendlymorefriendlymostfriendlyfriendlierfriendliestgoodbetterbestmany/muchmoremost,原级,比较级,最高级,总结：形容词和副词比较等级构成的规律一.规则变化：1.单音节和部分双音节词,在词尾直接加-er,-est2.以字母e结尾的,加-r,-st3.以重读闭音节结尾且末尾只有一个辅音字母，双写此字母,再加-er,est4.以“辅音字母+y”结尾的，把y变成i，再加-er,est5.多音节词和大部分双音节词,在词的前面加more或most6.有些双音节词既可用more,most形式，又可用-er,-est形式二.不规则变化,请给出下列形容词或副词的比较级和最高级tallnearlargeablethinhotfunnyhappybeautifulquicklyquietlittle,tallertallest,nearernearest,thinnerthinnest,ablerablest,largerlargest,hotterhottest,funnierfunniest,happierhappiest,morebeautifulmostbeautiful,morequicklymostquickly,quieterquietestmorequietmostquiet,lessleast,请你牢记：一，要双写再加-er,-est的词有哪些？,hotbigfatthinredwetsadglad,二.不规则变化的词有哪些？,温馨提示：类似slowly,quickly这样的双音节词，虽然也是辅音字母加y结尾，但这里的-ly是表示副词的后缀，因此比较级和最高级的构成是在单词前加more和most。2.强调程度时，形容词和副词前可加上too,very,so,quite等。比较级前则要加上much,even,alittle,alot,still,abit等词(组)，表示程度。3.farther常指时间、距离上的远。further可以代替farther，还常用于引伸和抽象的意义，表示“进一步，更深刻，更深入等”。4.older表示年龄大小或年代的久远，elder表示兄弟姐妹之间的长幼关系。,形容词和副词原级的用法：,2.as+原级+as“和一样”,Youareastallasme.=YouareastallasI(am).HehasasmanybooksasI(have).Thiscomputerrunsasfastasthatone.,3.notas(so)+原级+as“不如/没有”,Thisjacketisnotas(so)cheapasthatone.Shehasnotas(so)manybooksasIhave.Henrydoesntstudyas(so)hardashiselderbrother.,注：as在这里既可作介词又可作连词。作介词时，后接人称代词的宾格。作连词时，后接一个省略的比较状语从句。,用来直接描述人物或动作。Johnisatallboy.Rabbitsrunfast.Ourcountryisbeautifulandstrong.,形容词和副词比较级的用法：,1.比较级+than“比更”,Youaretallerthanme.=YouaretallerthanI(am).Idontthinkhiswritingismorebeautifulthanyours.,3.比较级+and+比较级“越来越”,Theweatherisgettingwarmerandwarmer.Ourschoolisgettingmoreandmorebeautiful.,注：than在这里既可作介词又可作连词。作介词时，后接人称代词的宾格。作连词时，后接一个省略的比较状语从句。,4.the+比较级,the+比较级“越,越”,Themoreexerciseyoudo,thehealthieryouwillbecome.,2.比较级(特殊疑问句)，or?“哪个更?”,Whichislonger,thisoneorthatone?,NotsomuchAasB和moreAthanB与其说A不如说B，与其说B不如说AJamesisnotsomuchawriterasareporter.詹姆士与其说是作家，不如说是记者。Sheismoreshythanunsocial.与其说她孤僻，不如说她太腼腆。,Allthe+比较级，意为“更加”Withsuchaneconomicpolicy,therichwillbecomeallthericher.Alongdelayedhoeletterisallthemorewelcome.,Thetallerofthetwo,两者进行比较，比较级前面有定冠词the，含有选择的意思。Thepictureistheprettierofthetwo.Youmaytakethelongerofthetwopencils.,表示最高级意义的几种特殊形式,As+原级+asany/everAs+原级+ascanbeNothingno+so+原级+asNothingno+比较级+than比较级+thananyotheranythingelseNever+比较级Examples:,Sheisasbrightasanyintheschool.最聪明的学生Heisashappyashappycanbe.幸福无比Nothingismorepreciousthanhealth.最宝贵的Nooneissodeafasthosewhowontlisten.最聋者莫过于不听劝的人Sheismorecarefulthananyother.比任何人都细心Ineverreadamoreinterestingnovel.从来没有读过,形容词和副词最高级的用法：,the+最高级+(名词)+表示范围的短语或从句“是最”,Bobisthetallestboyinourschool.HeisthekindestmanthatIhaveevermet.LiTaojumps(the)farthestofall.Sheisthemostcarefulstudentofusthree.,4.oneofthe+最高级(形)+名词(复)+表示范围的短语“是当中最之一”,ShanghaiisoneofthebiggestcitiesinChina.,注:形容词最高级前一般要加the,副词最高级前可加可不加,3.最高级(特殊疑问句)，or?“哪个更?”,Whoistheyoungest,Jim,TomorJenny?,2.thesecond(third)+最高级+(名词)+表示范围的短语“是第二(三)”,TheChongmingIslandisthethirdbiggestislandinChina.,形容词和副词比较级和最高级用法中比较容易出错的地方,Correctthemistakes:Maryshairislongerthanmysister.TheweatherinBeijingiscolderthaninShanghai.Theapplesinthisbasketarebetterthantheminthatbasket.TheChangjiangRiverislongerthananyriverinChina.ChinaislargerthananyothercountryinEurope.HisolderbrotheriselderthanI.Ourcountryisgettingmorebeautifulandmorebeautiful.Thisclassroomisthreetimesasbiggerasthatone.Whoistalleststudentinourschool?Whichdoyoulikebetter,apples,bananasorpears?,_,mysisters,_,that,_,those,_,anyother,_,any,_,elder,_,older,_,moreandmore,_,big,_,thetallest,_,(the)best,Correctthemistakes:11.Thisboxismoreheavierthanthatone.12.Tomistheyoungestinthethree.13.Heistallerofthetwo.14.Todayisourthebusiestday.15.IthinkmathisverymoredifficultthanChinese.16.Therearemuchmorepeopleinthestreetthanusual.17.MikeissotallasJack.18.LiYingjumpedfartherthanJimjumped.19.TheYellowRiveristhesecondlongerriverinChina.20.Wemustgetfartherinformation.,_,heavier,_,of,_,thetaller,_,our,_,much,_,many,_,as,_,(did),_,longest,_,further,
