规定 关于下班后关闭电源的规定党章中关于入党时间的规定公务员考核规定下载规定办法文件下载宁波关于闷顶的规定 ，好像没觉得噪音打扰了他人或对他人有害。t5t6A:的确如此，但是越来越多的人渐渐知道噪音干扰是多么有害了。中国的一些城市已经开始减少道路上的噪音，而且十分有成效。B:那太好了。在一些国家，在城市里任何一条街道上鸣汽车喇叭都是违法的。A:我想我们应该就此制定更严格的法律，更重要的是要实施。t6B:公平地讲，很难一下子完全控制污染。这需要时间，需要钱。A:但是已经有所好转。政府已经花大力气提高人们对环境保护重要性的意识，也采取了措施控制污染。顺利的话，我们有望在不久的将来生活在一个更干净、更健康的城市。oneofthesedaysItmustbeterriblelivingthere.—Livingtheremustbeterrible.Theintroductoryitisaformalsubject,whereasthe-ingparticiplelivingistherealsubject.AnotherexampleItisgreatfunboatingonthelake.ItalldependtheCleanAirAct—ThiswastheresultoftherecommendationsmadebytheBeaverCommitteewhichwassetuptoinquireintothequestionofurbanpollutioninBritain.ThecommitteewassonamedbecauseitschairmanwasSirHughBeaver.atrade-offtheThamesisswarmingwithfish—theRiverThamesisfulloffishthatmoveaboutbusily.Thenamesofriversareprecededbythedefinitearticlethe.e.g.theYangziRiver,theYellowRiver,theHudsonRiver,theRiverMississippione-waybusridetreatmentdevices—devicesusedtotreatsmoke,dust,andwaterpollution治理三废设备ajohnmoreandmorepeoplehavecometoknowhowharmful...—moreandmorepeoplebegintoknowhowharmful...Theinfinitiveaftertheverbcomeexpressesanactionthattakesplacegraduallyoversometime.AnotherexampleAfterworkingwithMrs.Brown,whoappearedquitehard-hearted,inthesameofficeformanyyears,I’vecometoseethatshehasaheartofgold.Incidentallymakestricterlawstothateffect—makestricterlawswiththeintentiontoforbidcarhornsblowinginthestreets.ThewordeffectreferstowhatBsaysintheprecedingline“it’sagainstthelawtoblowcarhornsinanystreetintown.”afford“doawaywith...”—terminate,getridof;abolishsth.e.g.1)Whynotdoawaywithallthejunkinyourroom?Itisgettingmoreandmoreuntidy!2)Howcouldtheydoawaywithalovelyoldbuildinglikethatandputacarparkthereinstead?3)Theseridiculousrulesandregulationsshouldhavebeendoneawaywithyearsago.every“addto…”—increaseorhaveanincreasedeffect;“addsth.tosth.”—putsth.togetherwithsth.elsesoastoincreasee.g.1)Hiswordsdidnothingbutaddedtomyanger.2)Thebadweatheronlyaddedtoourdifficulties.3)Teachersshouldexercisetheirimaginationandaddarttotheirteaching.1)Tobringthenoisychildrenundercontrol,theteacherstoldthemthestoryof“BuzzyBees.”2)Hundredsoffiremenhavebroughtawildfirespreadoverninesquarekilometersoflandundercontrolafterbattlingtoputouttheflamesfortwodays.3)ThePrimeMinistersaidyesterdaythatthegovernmentismakingalleffortstobringthehighinflationundercontrol.befamousfor“bring…undercontrol”—subdueormastersth.e.g.SampleOutlineforRetelling:B,astudentfromEngland,istalkingtoAaboutthepollutionproblem.1.BtellsAaboutLondonatpresent:thestepsthathavebeentakenbythegovernmentandthechangethathastakenplace.2.AandBtalkaboutthepollutionprobleminChina:1)airpollutioninfactoryzones;Retelling_1Retelling2)noisepollutionincitystreets;3)AtellsBthattheChinesegovernmenthastakensomemeasurestocontrolpollution.Samples1Samples1SampleA:HiJohn!HowdoyoulikeyourlifeinChina?B:Awesome!Butthere’sonethingI’mnotusedtoyet.Pollution.A:I’msorrytohearthat.Wealsoworryalotaboutfoodsecuritytoday.B:Well,theairqualityisreallybad.YouknowIenjoyjoggingeverymorning,butnowI’mthinkingofgivingitup.Samples2A:You’refromLondon.SoisLondonstillacityenvelopedinfogs?B:Notatall.Londonisnowacleancity.In2012weheldtheOlympicGamesthere.AthletesfromallovertheworldloveLondon.A:Sohowdidyouimprovethesituation?B:Well,ourgovernmentpassedtheCleanAirActin1956.Sincethen,theairqualityhasbeenbetterandbetter.A:Inourcity,mostfactorieshavebeenrelocatedtothesuburbs,buttherearestillafewfactoriesthatspitpoisonousgasintothesky.B:Thegovernmentneedtotakefurthermeasurestoimprovethesituation.A:Andthenoisepollutionisalsobad.Thoughblowinghornsisforbiddeninthedowntownarea,therearestillmanydriverswhoignoretherules.B:Itseemstomethatdriversshouldraisetheirawarenessofnoisepollution.Samples3A:You’reright.That’swhyourgovernmentislaunchingabigcampaigntohelpcitizensrealizevarioussourcesofpollutionandcontributetoacleanerenvironment.B:I’mgladtohearthat.Samples3SomephrasesandsentencesframesyoumightuseReferenceRole-Play-mainSamplerolecardsSituation&RolesSituation&Roles_1MoreAboutPollutionControlSituation:DaveandZhaohavetalkedabouttheimportanceofenvironmentalprotectionandthemeasurestakentocutdownsmokeanddustfromfactoriesandtoreducestreetnoise.NowtheygoontalkingaboutlandandwaterpollutionandsoilerosioninChina.Situation&Roles_2InformationaboutlandandwaterpollutionandsoilerosionCauseResult1.Waterpollution:alotofharmfuleffluentsfromfactoriespouredintotherivers2.Landpollution:littlecontrolovertheuseofpesticidesandchemicalfertilizers3.Soilerosion:carelessandindiscriminatefellingoftrees1.drinkingwaterpolluted;cropaffected2.hightoxicresidueinvegetablesandgrain;harmdonetosoil3.largenumberofforestsdestroyed;andsoilcarriedawaybywindandrain,leavingbarrenlandSituation&Roles_2Roles:Dave—askingquestionsaboutwaterpollution,landpollutionandsoilerosioninChinaZhao—tellingDavewhatsheknowsaboutwaterpollution,landpollutionandsoilerosioninChinaSomesentencesandsentenceframesyoumightuse_1Somephrasesandsentenceframesyoumightuse:contributetothepollutionproblembeharmful/detrimentalto…generatepollutantscausedamageto…leadtoanincreaseinairpollutionresult
