yotherbookhere.比擬級+than+theother+復數(shù)可數(shù)名詞Thisappleisbiggerthantheotherapplesinthebasket.五、注意1.形容詞最高級前一定要有定冠詞the，而副詞最高級前那么不需要。eg：Whatanimalsrunfastest?Theyrunfastestintheworld.2.形容詞的最高級可被序數(shù)詞修飾，表示“第幾〔長、大、高…〕”，形容詞的最高級前有物主代詞時，不加the。eg：LucyisthesecondtallestgirlinourfamilyTodayismyhappiestday.【經典例題】1.—“FoodSfatety”problemisbecomingtheseday.—Ithinkso，Thegovernmentmustdodealwithit.〔2016·山東〕A.smallerandsamllerB.worseandworseC.betterandbetterD.nicerandnicer2.Heisalittlethanyou，butheisasasyou.〔2016·新疆〕A.thin；strongerD.thinner；strongerC.thinner；strongD.thin；strong3.—HaveyouwatchedABiteofChinarecently?—Ofcourse.IdobelieveChinesefoodis____intheworld.(2016·山西)A.themostdeliciousB.moredeliciousC.delicious4.Withthedevelopmentofmodernscience,It’s______forustogetinformationfromallovertheworld.A.slowerB.busierC.harderD.easier5.Theboxwas_____thanIhadexpected.IwasoutofbreathwhenIgothome.(2016·呼和浩特)A.moreheavierB.muchheavierC.littleheavierD.veryheavier6.—Doyoulikeeatingfish，WangHan?—Ofcourse.Nothingcanbe_______，Ithink.(2016·嘉興)A.delicious
