过去式（pasttense）是英语语法的一种，表示过去某个时间里发生的动作或状态。一般过去式的动词通常用动词的过去式形式来表示，而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。•Igotoschoolbybus.•Iwenttoschoolbubus.•go-went（不规则动词变过去式）•Ilikeskating.•Ilikedskating.•like–liked(规则动词变过去式)WonderfulplacesthebeachthegardentheislandDadvisitedsomebeautifulplaces.Thegardenwasmorebeautifulthanthebeach.Theislandwasthemostbeautiful.roselilybauhinia紫荆花Isawsomebeautifulflowers.Thelilywasmorebeautifulthantherose.Thebauhiniawasthemostbeautiful.英['bɔ:ɪnjə]…beautiful……morebeautifulthan……themostbeautiful…LongadjectivesExamplesComparatives:LongadjectivesUsethewordmoretomakethecomparativeform.Mosttwo-syllableadjectiveswhichdonotendin–y（大多数双音节形容词而且不是y结尾）MaryismorepolitethanCindy.TomismorehelpfulthanPeter.Candyismorehard-workingthanMaggie.Joeismoregood-lookingthanTom.Alladjectivesofthreesyllablesormore（三音节形容词或多音节形容词）Practice1polite2careful3beautiful4dangerous5interestinge.g.helpfulmorehelpfulmorepolitemorecarefulmorebeautifulmoredangerousmoreinterestingUsethe+mostbeforelongadjectivestomakethesuperlativeform.Themelonisthemostexpensivefruit.$5$10$30expensiveSuperlatives:LongadjectivesPractice1interesting2exciting3beautiful4dangerousthemostinterestingthemostexcitingthemostbeautifulthemostdangerousComparatives&SuperlativesAdjectiveComparativeSuperlativegoodSomeadjectiveshavespecialforms.betterthebestbadworsetheworstPaulineisagoodstudent.Maryisabetterstudentthanher.Cherryisthebeststudentinherclass.CherryPracticee.g.bigbiggerthebiggestfatfatterthefattest1hot2long3nice4heavy5strong6hungryhotterthehottestlongerthelongestnicerthenicestheaviertheheavieststrongerthestrongesthungrierthehungriest7bad8good9enjoyable10exciting11noisy12beautifulworsetheworstbetterthebestmoreenjoyablethemostenjoyablemoreexcitingthemostexcitingnoisierthenoisiestmorebeautifulthemostbeautifulPractice
