修饰。如：HeismuchmoreseriousthanSam.,3)形容词比较级后面往往用连词than连接另一个比较的人或事物,但在上下文明确的情况下,形容词比较级可单独使用。如：Mysisteristall,butmyauntistaller.我姐姐个子高,但我姑姑个子更高。4)进行比较的人和物必须是同一类。Mybooksaremorethanyours.Ihavemorebooksthanyou.,Exercise,一将下列形容词变成比较级形式：,oldfatyounguglyhighlowlightwhitesunnyhotcool,older,fatter,younger,uglier,higher,lower,lighter,whiter,sunnier,hotter,cooler,二、词汇,1.Imtallbutmysisteris_(short).2.Mymotherhaslonghair,andmysisterhas_(long)hair.3.Thislittlebabyis_(outgoing)thanthatone.,shorter,longer,moreoutgoing,4.Insomewayswelookthesame,insomewayswelook_(不同).5.Annisavery_(安静的)girl,shehardlymakesnoise.,different,quiet,1.Thetwins_lovelygirls.A.areallB.arebothC.bothare2.IlikedrawingandIamgood_it.A.inB.onC.at3.Thatboxis_thanothers.A.moreheavierB.heavyC.muchheavier,三、单项选择,B,C,C,4.Sheisthreeyears_thanIam.A.oldB.moreoldC.older5.Ithinkagoodfriendshouldmakeme_.A.laughB.laughingC.tolaugh,C,A,6.Lucyisveryshort,butsheis_thanhersister.A.shorterB.longerC.tallerD.older7.Frankis_friendlythanhisbrother.A.alittlemoreB.afewmoreC.muchD.alittle8.Samis_atChinesethanJim.A.goodB.wellC.betterD.gooder,C,A,
