单元：Unit1Talesoftheunexplained板块：WelcometotheunitThoughtsonthedesign:本单元的学习内容主要是关于一些世间未解之谜。作为本单元的第一课时，主要是起热身作用，将鼓励学生充分发挥他们的想象力，同时还将充分利用网络、报纸、电视新闻等多种渠道的信息让学生对后面即将要学的内容有个粗略的了解，希望借此来激发学生对将学内容的兴趣，培养学生探索发现问题的能力和英语口语表达的能力，并将学习本节课教材中出现的一些重点词汇及句型。Teachingaims:Afterlearningthissection,thestudentswillknowaboutsomemysteriousandunexplainedphenomenaintheworld.Theirabilitytomakefulluseofresourcestosearchfortheinformationtheyneedandsharetheinformationtheygetwithotherswillbeencouraged.Meanwhile,studentsareexpectedtodescribewhattheyhaveknownaboutthepostersandwhattheyareeagertoknowabouttheunexplained.Theirinterestinscientificmysteriesshouldbestimulatedandtheirabilitytofindsolutionstoproblemsshouldbecultivated.StudentswillbeencouragedtocommunicatewithclassmatessothatnotonlycantheinformationandtheirimaginativeideasbesharedbutalsotheiroralEnglishcanbeimproved.Besides,someusefulwordsandexpressionsinthispartwillbetaughtsothatthestudentswillknowhowtousethem.Teachingprocedures:Step1Lead-in1.Groupdiscussion:Inyouropinion,whatisthemostbeautifulthingonecanexperience?Why?(PPT4)2.Warm-upquestions:●Doyouwanttoknowhisopinionofthemostbeautifulthingonecanexperience?—Introducehissayingaboutmysteries(Themostbeautifulthingonecanexperienceismysteries.Theyaretrulythebasisofallartsandsciences.PPT.6)andleadtothetopicofthisunit.(Soyousee,mysteriesareofvitalimportancetotheworld.That’swhyweshallbegintolearnsomethingaboutthem.Bb:Thetopicoftheunit.Thenwhatkindofattitudeshouldweadopttowardsmysteries?—Bb:showinterestin…;becuriousabout…;tracethecausesof…;analyze…;cooperatewith…;seekhelpfrom…;workintelligentlyandindependently;findsolutionsto…Beforewetakeuptheunit,Ihavetwomorequestionsforyou.)Let’swatchashortvideo,what’sflyinginthesky?IsitaUFO?Whatotherunexplainedthingsdoyouknowabout?[设计说明](1)以问题讨论开始，不仅可让学生发挥他们的想象力，还可激发他们的学习兴趣。(2)以爱因斯坦以及他关于神秘事物的名言为例,引出本单元话题，同时旨在激发学生探索世间奥秘的兴趣。同时结合一段UFO飞行的视频，激发学生对未解开之谜的探讨。(3)其中的板书设计旨在指导学生在探索发现问题和解决问题时需要具备哪些常见的基本条件，我认为这应该是本单元的学习目的之一，同时也希望能借此适当丰富一下学生的词汇。(4)图片展示是为了帮助学生回答问题，最后一个问题是为活跃课堂气氛，也希望能帮助增强学生的自信心。Step2Posters1.Pairwork:●Pleaseopenyourbooksandlet’slookatpageone.Readtheinstructionsandfocusonthefivepicturesandillustrationsfirst.Thenworkinpairstofindtheanswertothefollowingquestions.(PPT11-12)(1)Dothefivepictureshavesomethingincommon?Ifso,whatisit?—unexplained;nosatisfactoryanswers;mysterious;noevidencetoprove…;(2)Canscientistsexplainthesephenomena?(3)Howdoyoufeelaboutthem?●Thinkofasmanyexpressionsaspossibletoanswerthequestionsabove.Trytomakeupsomesentencesandreadthemtotheclass.FirstIwillofferyousomeexamples.ppt13—Theyaremysteriousbecausenosatisfactoryanswershavebeenofferedtoexplainthemsofar.Thoughthesemysterieshavepuzzledpeopleforalongtime,theystillshowgreatinterestinthem.Peoplefeelpuzzledbythemysteries…[设计说明]本环节旨在激发学生兴趣，培养观察分析问题能力，同时旨在鼓励开口，促进口语提高。2.Groupdiscussion:●Talkaboutthepicturesonebyone.(Dividethewholeclassintofivegro...
