Thistheateristhecheapestofthethree.注意使用最高级时应注意以下几点：

形容词的最高级

(1)表示“最……之一”的句式，要用oneofthe+形容词最高级+复数名词。例如：JingjiangHotelisoneofthebiggesthotelsinourcity.Lisaisoneofmybestfriends.

(2)当最高级前面有物主代词或名词所有格时，不加定冠词the。例如：TomisLucy’sbestfriend.Tuesdayisherbusiestday.(3)最高级前可加序数词。eg.TheYellowRiveristhesecondlongestriverinChina.(4)形容最高级修饰作表语或介词宾语的名词，代词时，

被修饰的词往往省略。eg.Heisthelaziest(student)inourclass.(5)形容最高级用在选择疑问句中，结构为：Who/Which...,A,BorC?WhoisthebestEnglishteacher,Mr.Zhang,MissLiorMissWang？2.形容词比较级和最高级的构成规则变化一般情况下，单音节或双音节的形容词比较级直接加-er,最高级直接加-est。如：

clever—cleverer—cleverestcheap—cheaper—cheapestfew—fewer—fewestsmall—smaller—smallestyoung—younger—youngestb.以-e结尾的形容词，比较级+-r,最高级+-st。如：

large—larger—largestnice—nicer—nicestcute—cuter—cutestc.以辅音字母+y结尾的形容词，变y为i+er或+est

busy—busier—busiestheavy—heavier—heaviesteasy—easier—easiesthappy—happier—happiestdirty—dirtier—dirtiestd.以重读闭音节结尾，末尾只有一个辅音字母结尾的词，双写最后一个辅音字母，再加+er或+est。如：

big—bigger—biggestthin—thinner—thinnest

fat—fatter—fattesthot—hotter—hotteste.多音节和部分双音节形容词，需在原级前+more构成比较级，+most构成最高级。

important—moreimportant—mostimportantbeautiful—morebeautiful–mostbeautiful

difficult—moredifficult—mostdifficult3.不规则变化：原级比较级最高级good/wellbetterbestbad/ill/badlyworseworstlittlelessleastmany/muchmoremostfarfarther/furtherfarthest/furthestoldolder/elderoldest/eldest最高级规则变化口诀：最高级，很容易，一般词尾加est。(cheap-thecheapest)词尾若有哑音e，直接就加st。(close-theclosest)重读闭音节，单辅音字母要双写。(big-thebiggest)辅音字母加y，记得把y变为i。(friendly-thefriendliest)多音节，考考你，themost到底加哪里？(popular-themostpopular)复习：形容词最高级的构成A:tallshortquickthicklightcoolwarmquietwildcalm--estB:
