Unit4PublictransportWelcometotheUnitandwordpower教学设计单元：Unit4Publictransport板块：WelcometotheunitandwordpowerThoughtsonthedesign:鉴于本单元的Welcometotheunit和wordpower都涉及到各种公共交通工具以及不同交通方式之间的特点，内容有重复之处，所以对两部分进行整合调整，放在一个课时进行教学。本节课以看、听、说、读为主，首先是温故知新，学生思考有关交通的词汇，教师帮助补充各种公共交通的方式及其优缺点，其次探索新知识，了解各种交通道路的名称，然后使用新知识，利用前面所学知识来阅读文章，最后是拓展知识，学习与使用交通有关联的特殊词汇。学生在小组讨论中分享观点、操练词汇，并在各种设置的情境中运用所学知识。Teachingaims:Afterlearningthisperiod,thestudentswillbeableto:1.knowdifferentmeansoftransportandtheirmainfunctions;2.comparetheadvantagesanddisadvantagesofpublictransport;3.understanddifferentnamesofroads;4.enlargetheirvocabularyrelatedtotransport.Teachingprocedures:Step1BrainstormingHaveafreetalktoreviewtheword“transport”,suchas“Howdoyougotoschooleveryday？”“HowdidyougotoBeijingthissummer?”andthencategorizethedifferentwaysthatwecantravelinaflowchart,referringtopage54wordpowerPartB.(PPT4―5)Step2SharinginformationanddiscussionDiscussthesevenpicturesinthebook(Page49).Encouragethestudentstoexpresswhatisincludedin“publictransport”(PPT6).AskstudentstohaveagroupdiscussionandmakeacomparisonamongallthemeansoftransportmentionedinthissectionBusesandCoachesBuseshaveroutes.Theypickupanddropoffpeopleatdifferentplacesontheroute.Itisapopularmeansoftransportwithinacity.(PPT7）Coachesarebusesthatcarrypeopleoverlongdistances.(PPT8)ShipsandaeroplanesShipswereapopularwaytotravelfromplacetoplaceinthe20thcentury.(PPT9)Aeroplanesareusedtotravelquicklyoverlongdistances.(PPT10)UndergroundtrainsTheUndergroundtrainshavebecomepopularincrowdedcities.(PPT11)high-speedtrainshigh-speedtrainsrunmuchfasterthannormaltrains.(PPT12)Yourchoice(PPT13)Situation1IfyouaregoingtoShanghaifromNanjing,whatmeansoftransportwouldyouuse?Why？(IwouldchooseMUtrainbullettrain动车组becauseitisextremelyfastandcomfortable.)Situation2IfyouwanttogotoTaiwanfromXiamen,willyougotherebyshiporbyplane?Why?(Iwouldchoosetotravelbyaeroplaneratherthanbyship.Therearetworeasons.First,airtravelisquicker.Businessmenwhovaluetimeregularlytravelbyaeroplanebecauseofitsspeed.Second,travellingbyplaneismorecomfortablethanbyship.Withtheimprovementoftechnology,manyairlinecompaniesofferexcellentservicesatareasonableprice.)GroupDiscussion:Advantagesanddisadvantagesofthepopularmeansoftransport(ppt.15-20)MeansoftransportAdvantagesDisadvantagesBusesorcoachescheapandconvenienteasilytrappedintrafficjams;notsocomfortableduringpeakhoursbecausetheyareusuallyverycrowded;causepollutionUndergroundfastandconvenient;producefewertrafficaccidents;comfortableExpensivetobuildShipscomfortablenotcomfortableforthosewhoareseasick;relativelyslow;thesafetyofthetripwouldbeaffectedbystormsaeroplanesfastandconvenient;relativelythesafestwayoftravelrelativelyexpensiveYourconclusion:Whydoyouthinkweneedallthesedifferenttypesoftransport?(Differenttypesoftransportcanmeetdifferentcustomers’needs.Eachtypeoftransporthasitsownstrengthsandlimitations.Andundercertainconditions,peoplemayprefertouseoneratherthananotherone.Ienjoyridingmybicycleontheavenue.Whataboutyou?Step3Wordpower—VocabularylearningAskstudentstoreadPartAonPage54(PPT22),understandingdifferenttypesofroads.Thenintheformof“Q...
