结构相结合的特点。UsingLanguage是对所学知识的综合运用。Readingandlistening是课文的延伸，先读一段关于恐龙的说明文，简单介绍其种类及灭亡原因；然后听一段关于dodo的材料并根据所听材料做题，抓住细节且要顾及中心思想。Speakingandwriting借dodo的故事引导学生选择他们知道的一种濒临灭绝的动物并分析这种结果的原因。在讨论的过程中练习打算，目的及意图的表达法。与其他小组交流自己所选的动物及拯救措施，选取较优的计划报告给全班同学。之后，根据讨论的内容，借助课本所提供的功能句式WWF写一封信，希望该组织能帮助学生实现这一保护措施。教材已为学生列出写作步骤，学生只需根据本单元内容组织语言，丰富内容。总之，通过本单元的系统学习，让学生了解当今珍稀动物的境况，激发他们热爱自然，保护自然的热情；并能够丰富语言知识，提升用英语表达观点的能力。2.教材重组2.1从话题、内容和功能上分析WarmingUp与Workbook中的LISTENING&TALKING一致，旨在启发学生讨论、思考本单元话题，可以整和成一节任务型“听说课”。2.2可将Pre-reading、Reading、Comprehending三个活动整和成一节“阅读课”将UsingLanguage中的Reading与Workbook中的READINGTASK整和成一节“泛读课”将LearningaboutLanguage与Workbook中的USINGWORDS&EXPRESSIONS,USINGSTRUCTURES结合在一起，上一节“语法课”。2.5将UsingLanguage中就已经灭绝的物种dodo展开的听说写上一节“语言学习课”。将Workbook中的LISTENINGTASK、SPEAKINGTASK和WRITINGTASK上一节“语言实践课”。III.课型设计与课时分配（经分析教材,本单元可以用六课时教完）1stperiod2ndperiod1stperiod2ndperiod3rdperiodIntensiveReadingExtensiveReading4thperiodLearningaboutLanguage5thperiodUsingLanguage6thperiodIntegratingSkillsIV.Teachingplansforeachperiod分课时教案TheFirstPeriodListeningandSpeakingTeachinggoals教学目标Targetlanguage目标语言重点词汇和短语dieoutlossreservehuntzoneinpeacewilddecreasehuntingAbilitygoal能力目标Enablethestudentstotalkaboutendangeredwildlife、thereasonsfordisappearingandtheimportanceofprotectingwildlife.Learningabilitygoals学能目标Helpthestudentslearntotalkaboutendangeredwildlife,thereasonsfordisappearingandtheimportanceofprotectingwildlife.Teachingimportantpoints教学重点Howtotalkaboutendangeredspeciesofwildlifeandenvironmentalprotectionandhowtoexpressrefusingandgivereasons.Teachingmethods教学方法Elicitation,discussion,pairwork,ask-and-answeractivity.Teachingaids教具准备TheMultimediaComputer,aprojector,aboardandataperecorder.Teachingprocedures&ways教学过程与方法StepILead-inGetthestudentstotalkaboutsomeendangeredanimalstoleadthemtothisunit'stT:Morning,everyone!Lookatthescreen,please.Iwillshowyoupicturesofsomeanimals.Showthemthepicturesofsomeendangeredanimals.T:Talkabouttheminyourownwords.Thestudentsmayrefertothefollowingaspects:1.whattheanimalis;2.Itsappearance;3.reasonswhyitbecomeslessandless;4.whathasbeendonetoprotectit;5.otherthingsyouknowaboutit:whereitlives;whatitfeedson...S:ThefirstoneisGoldenMonkey.It'sverybeautifulandsmartItisalsoknownasGoldenSnub-nosedMonkey（仰鼻猴）orSichuanGoldenSnub-nosedMonkey.ItisendemictoChina.Itisthreatenedbyhabitatloss.S:ThesecondlovelyanimalisGiantPanda.ItcanonlybefoundinChina.Itfeedmostlyonbamboo,atallwoodyplantfulloffiber.ItlivesinafewmountainrangesincentralChina,inSichuan,Shaanxi,andGansuprovinces.It'sournationaltreasure.Weshouldtryourbesttoprotectit.S:Thethirdonemaybeadeer.S:No!It'sTibetanAntelope.TibetanantelopescomingfromthefamilyofBovidaearemainlydistributedoverQinghaiProvince,TibetanAutonomousRegionandXinjiangAutonomousRegioninChina.Itisindangernowbecausemanyofthemhavebeenkilled.T:Wonderful!Thankyou.Youknowsomuchaboutwildlife.Howaboutthefourthone?S:Iamsureitisakindofleopard,butIdon'tknowwhatkindofleoparditisexactly.T:Well,itiscalledCloudedLeopard（云豹），whichareoneofthefirstclassprotectedanimals.ItisfoundinsouthernChina,theeasternHimalayas,north-eastIndiaandsouth-eastAsia.Howaboutthefifthone?S:Tiger!T:Whatkindoftigerisit?...It'sSouthChinaTiger.We'lllearnittoday.OK,let'sgoon.S:InPicture6,therearetwoGiantSalamander*娃娃鱼),whichcanswimagainstthecurrentandcrylikebabies.T:Excellentwork!Well,canyoufindanythingcommonamongthem?Whatisit?S:Theyareallindanger.T:Welldone!Theyareallendangeredanimals.Ifyouwanttoknowmoreaboutthem,let'scometoUnit4WildlifeProtection.StepIIWarmingupGetthestudentstodoWarmingup.ScanningT:Next,readthroughthewordsinWarminguppart,andthenfindout:Whydidsomanywildanimalsdieout?Getthestudentstolookthroughthispart.Laterasksomeonetogivetheanswer.T:Who'dliketosaysomethingaboutthisquestion?S:Iftheirhabitatisthreatenedortheycannotfindenoughfood,theirnumbersmaydecrease.Asaresulttheseendangeredanimalsmayevendieout.T:That'sit!DiscussingGetstudentstotalkaboutthereportinWarmingupinpair.T:Today,moreandmorepeoplerealizetheimportanceofprotectingendangeredwildlife.HereisareportonsomeendangeredwildlifeinChina.Next,readthereport.Thendiscusswithyourpartnerabouttheseanimals.Youmayrefertothefollowingaspects:1.Whattheendangeredanimalsare;2.Whattheproblemis;3.ListoneoftheirhabitatinChina;4.HowtheanimalisafterconcernFourminutesforfreetalk,thenasksomestudentstosharetheiropinionswiththewholeclass.Sampleconversation:S1:Whatendangeredanimaldoyouknow?S2:OurNationalTreasure—Pandas.S1:What'stheproblem?S2：Theyareindangerforlackofbamboo,butrecentlytheirnumberisincreasingbecausemorebamboohasbeengrown.S]：It'ssaidthatalthoughChinawastheonlyhomeforMiluDeer,webroughtthemfromEngland.S2：Yes.TheydisappearedinChinabecauseoftoomuchhunting.Whatapity!S]:SodoSouthChinaTiger.Theyaresaidtobefiercebutsomehuntersarefiercer!S2：Icannotagreewithyouanymore.T:Welldone!DoyouknowanyotherendangeredwildlifeinChinathatisbeingprotected?Thinkaboutthatandthenmakealist.Sampleanswer:CrestedIbis/BrownEaredPheasant/Red-crownedCrane/WildYak/ChineseAlligatorStepIIIListeningGetthestudentstodoLISTENINGonpage62.Helpthemlearnmo
