Unit3Writingworkshop：A“for”and“against”Essay教学设计Unit3Conservation WritingWorkshop 写作课教学内容分析 【What】本课是北师大普通高中教科书（2019版）选择性必修一第3单元的Writingworkshop。本课的主题是A“for”and“against”Essay写一篇关于赞成和反对意见的议论文，是本单元的写作课。在课文中作者首先提出了“工厂化饲养动物”在全世界的普及这一热点且有争论的话题，然后从正反两方面论证“工厂化饲养动物”的优缺点，正面论证包括它能够以更低的价格，更高的产量为人们带来更多的食物；同时这一方式饲养的动物比在野外生长的动物还能更少遭到疾病的侵袭。反面论证包括工厂化饲养动物对动物们来说太过于残忍，是无视动物权利的表现，同时还会对环境造成负面影响，比如产生更多的垃圾，使用更多的化学药品，而这些会加剧对环境的破坏。最后，作者对正反论证进行总结：尽管这种工厂化饲养动物的方法可以生产更多更便宜的食物，但是它对我们的环境以及动物都产生了不良影响；然后强调论点：我们应该尽量减少这种工厂化饲养动物的行为。【Why】作者通过对比FactoryFarming的优缺点，运用多种论证方法在基于正反两方面分析的基础上向我们证明这种工厂化饲养动物的模式长远来讲对环境不利，应该尽量减少。【How】本文A“for”and“against”Essay对篇章的论据运用了多种方法进行论证，包括citingideasfromexpertsandauthorities，usingdata,1.According1.Accordingtoaninstitute,74%oftheworld’spoultry…areproducedinthisway.例2....itprovidesmorefoodforaworldpopulationthathasalreadyreachedsevenbillion,accordingtotheUnitedNations.3...itcreatesalotofwasteproducts,andusesalotofchemicalstocontrolinsectsanddrugstotreatdiseases(UKFarmingToday,2013).usingparisonandcontrast,例如：Themainargumentforfactoryfarmingisthat,apartfrom...,moreover...Ontheotherhand,opponentsoffactoryfarmingsaythatitiscrueltotheanimals,givingexamples,例如Forinstance，manyfarmanimalsarekeptinsmallspaceswheretheycanhardlymove.纵观全文，语篇结构清晰：第一段提出了“工厂化饲养动物”在全世界的普及这一热点且有争论的话题,第二段对人们支持“工厂化饲养动物”进行论证,第三段对人们反对“工厂化饲养动物”进行论证，第四段先对前面的论据进行总结然后表明了自己的观点。语篇从现象开始，论证详实，数据精准、权威，观点明晰；能够引起读者的共鸣与思考。
