词性被改变，通过单词活用来吸引观众的注意力，给他们留下深刻印象。如苹果公司的口号“ThinkDifferent（非同凡想）”,这里Different是形容词当副词用了。本句中，作者也是将local和organic作为名词使用，获得了较理想的排比和押韵效果。,Whenitrains,thesechemicalsflowslowlyintotheground,orrunoffintoourwaterways,poisoningourwatertoo.,18,Backgroundinformation,foodsystem,食物系统。食物系统包含食物从田间地头到餐桌所涉及的种植或养殖、收获、加工、包装、运输、销售、消费以及废弃物处理的所有过程和环节。,19,Backgroundinformation,基因工程。指按照人们的愿望，进行严格的设计，通过体外DNA重组和转基因技术，赋予生物新的遗传特性，创造出更符合人们需要的新的生物类型和生物产品。虽然基因技术可以培养出优质、高产的农产品和畜牧产品，但是它对环境和健康可能会产生的不利影响也越来越受到人们的关注。,geneticengineering,20,Backgroundinformation,常规农业和有机农业。常规农业是当前世界农业在实施运作上占主导地位的农业发展模式，以系统的开放性、资源的高投入和生产的高效率为基本特征。与常规农业不同，有机农业在生产中完全或基本不用人工合成的肥料、农药、生长调节剂而采用有机肥满足作物营养需求。,conventionalfarmingandorganicfarming,21,Backgroundinformation,BirkeBaehr,伯克巴尔，美国学生，动物保护协会志愿者，9岁时开始关注可持续发展的有机农业并参与宣传。2010年他11岁时，受到TED的邀请发表了这篇题为“WhatsWrongwithOurFoodSystem?”的演讲，从一个孩子的视角发表对我们食物系统的看法，指出工业化食物系统对人类健康和环境的危害，倡议人们购买本地生产的绿色食品，支持有机农业的发展。,22,Backgroundinformation,TED,TED(指technology,entertainment,design，即技术、娱乐、设计)是美国的一家私有非营利机构，以其组织的TED大会著称。每年3月，TED大会在美国召集众多科学、设计、文学、音乐等领域的杰出人物，以演讲来分享他们关于技术、社会、人的思考和探索。TED大会希望传达这样一个的信息，即优秀的思想可以改变人们对这个世界的看法，使人们反思自己的行为。,23,Backgroundinformation,NFL,国家橄榄球联盟(NationalFootballLeague，NFL)是世界最大的职业美式橄榄球联盟，也是世界最具商业价值的体育联盟，由32支来自美国不同地区和城市的球队组成。目前联盟共有32支球队，分为两个联会：美国美式橄榄球联会和国家美式橄榄球联会。,24,Backgroundinformation,Cerealandflakes,Cereal可指一般谷物，而本文中的意思是营养麦片，是西式早餐中的常见食品，一般直接泡在水、牛奶或酸奶中吃，不加热，吃的时候适当加一些新鲜水果。也有干吃的，国外有些麦片即如同中国国内的爆米花，可以空口吃。常见的麦片有玉米片(cornflakes)、燕麦片(oatcereal)等。,25,DoingIt,Task1,Geneticallychangedseeds,Useofchemicals,26,EXAMPLE:,Corporationsarealwaystryingtogetkidstomaketheirparentsbuyunhealthyfood.Ihavefoundout/discoveredthatcorporationsarealwaystryingtogetkidstomaketheirparentsbuyunhealthyfood.,Ihavefoundoutthatgeneticallyengineeredfoodshavebeenproventocausecancerandotherproblemsinlabanimals.,Ihavediscoveredthatpeoplehavebeeneatinggeneticallyengineeredfoodsincethe1990sandmostpeopledontknowwhatshappening.,Ihavefoundoutthatconventionalfarmersusealotofchemicalfertilizersbecausethesoilhasnonutrients.,Ihavediscoveredthatchemicalssprayedonfruitsandvegetablesflowintothegroundorrunintoourwaterways,pollutingourwater.,27,Ihavediscoveredthatonafactoryfarm,animalsareill-treated.Largenumbersofanimalsareshutinsidetogetherwithverylittlesunshineandfreshair.,28,Ihavediscoveredthatonafactoryfarm,animalsareill-treated.Largenumbersofanimalsareshutinsidetogetherwithverylittlesunshineandfreshair.,Thegovernmentshouldsetregulationsandstandardstoinspectfoodproductionandensurefoodsafety.,29,Task2,EXAMPLE:Question:Whatdoyouthinkofthosefoodcorporations?Opinion:Itseemstomethatthosecorporationsarealwaystryingtogetkidstomaketheirparentsbuyunhealthyfood.,AskingforopinionsWhatsyouropinion(view)of?Whatdoyouthinkof?Howdoyousee?Whatshould?,GivingopinionsoradviceIthinkthatIbelievethatItseemstomethatWeshould,30,Host:Goodevening,Birke.Welcometoourtalkshow.Birke:Goodevening,Jimmy.Host:Inrecentyears,thebenefitsanddangersofgeneticallyengineeredfoodhavebecomethesubjectofheateddebate.Whatdoyou1)_it?Birke:Well,Ibelievethatgeneticengineeringis2)_.Host:Whatdangersdoesitbring?Birke:Geneticallyengineeredseedsareprocessedinalaboratory,andthenplanted.Ithasbeenproventhatfoodproducedwiththistechnologycan3)_.Whatsworse,itseems,makeadifferencenotintendedbynatureorganicfoodupcloseandpersonalgrazeongrasscausediseasesthinkoffarmersmarkets,thinkof,notintendedbynature,causediseases,31,tomethatmostpeopledontevenknowwhatshappening.Host:Whatdoyouthinkisthemostimportantthingthatpeoplecandotoavoidthedangers?Birke:Wecan4)_bychoosing5)_.Weshouldalsotrytobuyourfoodfromlocal6)_.Ifyouhaveachancetoseetheorganicfarm7)_,youmayfindtherecowsdo8)_andpigsdorollinthemud.,makeadifferencenotintendedbynatureorganicfoodupcloseandpersonalgrazeongrasscausediseasesthinkoffarmersmarkets,makeadifference,organicfood,farmersmarket,upcloseandpersonal,grazeongrass,32,Whynotrole-playtheconversationinfrontoftheclass?,33,Task3,Conventionalfarming,Organicfarming,34,Controlspestsandweedsmoreeffectively,Saferforhumansandtheenvironment,Moreharmfultohumanhealth,Moreexpensive,35,1A:Unlikeorganicfarming,conventionalfarminguseschemicalfertilizers.Whatdoesthismeantoourenvironment?B:Conventionalfarmingismoreharmfultosoilthanorganicfarming.2A:Unlikeconventionalfarming,organicfarmingdoesnotusechemicals.Whatdoesthismeantoourenvironment?B:Organicfarmingisnotasdangerousasconventionalfarmingtotheenvironmentandhumanhealth.,Next,EXAMPLE:,A:Unlikeconventionalfarming,organicfarmingdoesntusegeneticallyengineeredseeds.Whatdoesthismeantoourhealth?B:Organicfoodissaferforusthanconventionalfood.,TipsXismoreharmfultosoilthanY.XpollutestheenvironmentmorethanYdoes.XisnotasdangerousasYtotheenvironmentandhumanhealth.,36,3A:Unlikeconventionalfarming,organicfarmingtreatsanimalswell.Whatdoesthismeantoourhealth?B:Thequalityoforganicfoodismuchbetterthanthatofconventionalfood.4A:Unlikeorganicfarming,conventionalfarmingspraysharmfulchemicalstokillweedsandbugs.Whatdoesthismeantoourenvironment?B:Conventionalfarmingpollutestheenvironmentmorethanorganicfarmingdoes.,EXAMPLE:,A:Un
