Unit3WhatwereyoudoingwhentheUFOarrived?ByLiuKaifromAiXinMiddleSchool一单元分析本单元以“UFO”为话题展开一系列教学活动.通过UFO到达地球时不同人物的活动,学习过去进行时when/while的用法.观察图片和利用图片来培养学生情景思维和讲故事的能力,这是本单元的重点和难点.八年级学生对UFO会有强烈的好奇心和探索欲望,教材以次为入点,使原本枯燥的时态学习变得丰富多彩.教师可借助这点,引导学生开展丰富的想象,使课堂真正变成学科综合,心灵交汇的智慧场所.在本单元的教学全过程中,采用任务型教学方式,让学生通过独立学习,角色扮演,实践体验和合作交流来掌握本单元的英语知识和技能.开发学生的思维能力,发展他们的个性,使学生形成积极的情感态度,主动思维和大胆实践的过程.二学情分析学生在七年级下册已学过现在进行时,而且掌握了一些描述日常活动的短语,并能够使用现在进行时来描述日常活动,这有利于他们学习过去进行时.同时,八年级下的学生对看图讲故事已有一定的接触,这也有利于本单元故事讲述的顺利开展.三教学目标1语言技能目标(1)能谈论过去某个时刻正在发生的事情,如:Iwassittinginthebarber’schair.(2)能询问过去某个时刻正在发生的事情,如:WhatwereyoudoingwhentheUFOarrived?(3)能用过去进行时态讲故事.2语言知识目标(1)能用过去进行时态描述过去某一时间内正在发生的事,如:Iwasstandinginfrontofthelibrary.(2)能正确使用when/while引导的时间状语从句,如:Whilehewasbuyingasouvenir,agirlcalledthepolice.3情感态度目标(1)通过了解有关UFO的知识,培养学生从小热爱科学,勇于探索的精神.(2)通过课堂讨论,教育学生从小树立辨证的看待问题,乐观向上的人生观.4文化意识目标了解自然现象在语言学习中具有的文化涵义.5学习策略目标(1)认知策略:借助猜测的方法推测单词的意思,用归类的方法记忆单词.(2)交际策略:通过roleplay等的活动,培养学生的合作能力,并注意倾听他人的意见.(3)资源策略:鼓励学生通过各种手段,搜集有关UFO的不同信息,帮助学生拓展知识,开阔视野,提高自主学习的能力.(4)调控策略:通过课堂反馈和Selfcheck,让学生明确自己的学习状况,不断调整学习策略.四重点难点1教学重点:重点词汇:bathroom,bedroom,kitchen,bought,got,land,kid,climb,jump,shout,rode,ran,met,heard,told,became,flew,rang,cat,anywhere,happen,accident,plane,modern,kill,murder,bright,playground,bell,close,silence,meaning,earth,hero;重点句型:WhatwereyoudoingwhentheUFOarrived?Iwassittinginthebarber’schairwhenitarrived?Whilehewasbuyingasouvenir,agirlcalledthepolice.话题:以UFO为话题,讲述UFO到达地球时人们的活动:看图讲故事.2教学难点:能用过去进行时讲故事.教学过程:第一课时(1a—1c)通过教师做动作让学生猜测这活动来复习现在进行时态,向学生展示自己的住所来引出本课新单词.再利用图片呈现过去进行时,之后用pairwork来巩固,让学生猜我在做什么来引出UFO这个话题.从而顺利过渡到课文,并完成1a,1b.之后是一个pairwork再一次巩固重点句型和词汇.之后转入1c.用一个groupwork记者采访的活动开展.并把听力转化为口语练习.接着是一个语法总结,最后再利用旧教材初二下册Lesson95的图片让学生先口头叙述图片,为家庭作业写作做一个铺垫.Unit3WhatwereyoudoingwhentheUFOarrived?UFOWhatwereyoudoingwhentheUFOarrived?Unit3Period1bedroombathroombarbershopbarberkitchenWordstudyWhat’shedoingnow?Whatwashedoingatthreeo’clockyesterdayafternoon?Hefootball.wasplaying•.Heisplayingfootball.•Whatwasshedoingatseveno’clockyesterdaymorning?SheWhat’sshedoingnow?Sheisrunning.wasrunning.Whataretheydoingnow?TheyWhatweretheydoingattenlastnight?Theyaredancing.weredancing.AskandanswerinpairsWherewereyouat6:00yesterdayevening?Whatwereyoudoing?•1inariverswimming•2inaparkplayingbasketball•3inashopdoingsomeshopping•4athomecooking•5athomedoingmyhomeworkIwaswatchingaTVprogramaboutUFO.DidyouseeaUFO?UFO:UnidentifiedFlyingObject不明飞行物1.___Iwasinthebathroom.4.___Iwasinthekitchen.2.___Iwasinmybedroom.5.___Iwasinmybarbershop.3.___Iwasinfrontofthelibrary.6.___Iwasinthebarber’schair.dbacef1aATVreporterisasking“WherewereyouwhentheUFOarrived?”Matchthestatementswiththepeopleinthepicture.1bListentothereporter’squestionsandcirclethecorrectresponses.a.standinginfrontofthelibrary/studyinginthelibraryb.cleaningmyroom/sleepinglatec.makingamilkshake/cookingdinnerd.gettingoutoftheshower/talkingonthephonee.eatinglunch/cuttinghairgetout出去；离开getoutof从…出来getoutoftheshower洗完澡出来cut剪；切；割A:Whatwas/were…doingwhentheUFOarrived?B:…was/were…Reporter:So,whatwereyoudoingwhentheUFOarrived?Girl1:Well,Iwasstandinginfrontofthelibrary.Boy1:Iwassleepinglate.Woman1:Iwascookingdinner.Groupwork:•Reporter:Howaboutyou?•Man1:Iwasgettingoutoftheshower.•Man2:AndIwascuttinghair.过去进行时含义：表示过去某个时刻正在进行的动作。结构：be(was/were)+doing例句：Whatwereyoudoingatninelastnight?Iwastakingashoweratninelastnight.summary(7)(1)(2)(3)(8)(4)(5)(6)lookoutofhiswindowdrinksomewaterplaygamesboatbuysomefruitsellsomefruitreadnewspapersplayfootballfish1WriteashortpassageaboutthepictureInthepark.2MakeasurveyaboutwhatyourfamilyweredoingwhenyouarrivedhomelastFriday?Homework:第二课时(SectionA2a—3b)让学生齐唱“Ifyouarehappy”,活跃气氛.值日生上台汇报上节课布置的作业,然后完成2a,2b的练习.接着利用图片重点对when和while的用法作比较并总结.并做一个小练习.然后阅读3a的电子邮件,为图片排序.并按次序复述故事.Unit3WhatwereyoudoingwhentheUFOarrived?UFOWhatwereyoudoingwhentheUFOarrived?Unit3Period2___ThealienvisitedtheMuseumofFlight.___Thealienboughtasouvenir.___AUFOlandedonCenterStreet.___Thealienwentintoastore.___AnaliengotoutoftheUFO.22aListenandorderthesestatements[1-5].land5413alien1.Theboywaswalkingdownthestreet_____aUFOlanded.2.Thegirlwasshopping_____shesawthealiengetout.3._____thealienwasbuyingasouvenir,thegirlcalledthepolice.4._____thealienwasvisitingthemuseum,theboycalledtheTVstation.whenwhenWhileWhile2bListenagain.Completethefollowingsentenceswith“when”or“while”.Comparingthefollowingsentences:ThegirlwasdrawingwhentheUFOlanded.Whilethegirlwasdrawing,theUFOlanded.Whiletheywereswimming,thealiengotout.Theywereswimmingwhenthealiengotout.Hewastalkingonthephonewhiletheywereswimming.When和while的用法与区别•1）延续性动词和非延续性动词•延续性动词指动作可以延续一段时间，而不是瞬间结束。•如：work、study、drink、eat等。•非延续性动词指动作极为短暂，瞬间结束。•如：start、begin、hit、jump、knock等。•2）在本单元中，出现了以when和while引导的时间状语从句。•1when表示“当……的时候”。从句中既可用延续性动词，又可用非延续性动词，这些动词既可以表示动作，又可表示状态。从句中的动作既可和主句的动作同时发生，又可在主句的动作之前或之后发生。如：•MarywashavingdinnerwhenIsawher.•Theboywasstillsleepingwhenhismothergothomeyesterdaymorning.•2while表示“在……的时候”、“在……期间”。它强调主句的动作与从句的动作同时发生或主句的动作发生在从句的动作过程中。while从句中必须是表示动作或状态的延续性动词。如：•TheweatherwasfinewhilewewereinBeijing.•ShecalledwhileIwaso
