Thistheateristhecheapestofthethree.注意使用最高級時應(yīng)注意以下幾點：

形容詞的最高級

(1)表示“最……之一”的句式，要用oneofthe+形容詞最高級+復(fù)數(shù)名詞。例如：JingjiangHotelisoneofthebiggesthotelsinourcity.Lisaisoneofmybestfriends.

(2)當(dāng)最高級前面有物主代詞或名詞所有格時，不加定冠詞the。例如：TomisLucy’sbestfriend.Tuesdayisherbusiestday.(3)最高級前可加序數(shù)詞。eg.TheYellowRiveristhesecondlongestriverinChina.(4)形容最高級修飾作表語或介詞賓語的名詞，代詞時，

被修飾的詞往往省略。eg.Heisthelaziest(student)inourclass.(5)形容最高級用在選擇疑問句中，結(jié)構(gòu)為：Who/Which...,A,BorC?WhoisthebestEnglishteacher,Mr.Zhang,MissLiorMissWang？2.形容詞比較級和最高級的構(gòu)成規(guī)則變化一般情況下，單音節(jié)或雙音節(jié)的形容詞比較級直接加-er,最高級直接加-est。如：

clever—cleverer—cleverestcheap—cheaper—cheapestfew—fewer—fewestsmall—smaller—smallestyoung—younger—youngestb.以-e結(jié)尾的形容詞，比較級+-r,最高級+-st。如：

large—larger—largestnice—nicer—nicestcute—cuter—cutestc.以輔音字母+y結(jié)尾的形容詞，變y為i+er或+est

busy—busier—busiestheavy—heavier—heaviesteasy—easier—easiesthappy—happier—happiestdirty—dirtier—dirtiestd.以重讀閉音節(jié)結(jié)尾，末尾只有一個輔音字母結(jié)尾的詞，雙寫最后一個輔音字母，再加+er或+est。如：

big—bigger—biggestthin—thinner—thinnest

fat—fatter—fattesthot—hotter—hotteste.多音節(jié)和部分雙音節(jié)形容詞，需在原級前+more構(gòu)成比較級，+most構(gòu)成最高級。

important—moreimportant—mostimportantbeautiful—morebeautiful–mostbeautiful

difficult—moredifficult—mostdifficult3.不規(guī)則變化：原級比較級最高級good/wellbetterbestbad/ill/badlyworseworstlittlelessleastmany/muchmoremostfarfarther/furtherfarthest/furthestoldolder/elderoldest/eldest最高級規(guī)則變化口訣：最高級，很容易，一般詞尾加est。(cheap-thecheapest)詞尾若有啞音e，直接就加st。(close-theclosest)重讀閉音節(jié)，單輔音字母要雙寫。(big-thebiggest)輔音字母加y，記得把y變?yōu)閕。(friendly-thefriendliest)多音節(jié)，考考你，themost到底加哪里？(popular-themostpopular)復(fù)習(xí)：形容詞最高級的構(gòu)成A:tallshortquickthicklightcoolwarmquietwildcalm--estB:
