高中英语人教版选修7课件Unit3Period1Reading

1.培养学生阅读能力和技巧，skimming,scanning,summarizing等，并能快速的锁定所需的信息范围。2.使学生更好的了解海底生物，热爱生物，保护海洋环境。本节课是unit3underthesea的第一篇课文，设计的意图主要是通过任务型阅读，培养学生的阅读能力，即泛读和精读的能力，并能根据不同的题型选用不同的阅读方法。首先，用海底生物的图片法进行导入，激发学生的学习兴趣，从而自然过度本文的主题。其次，在新课讲授环节，设置了多样的题型训练学生的阅读技巧。Discussion环节，同学之间的讨论，增强了人际沟通能力，同时也提高了自身的口语表达能力，这也是新课标的重要任务之一。Haveyouseenplantsandanimalsthatliveunderthesea?Let’senjoysomebeautifulpictures.atanaquariumonaboattourinfilmsonTVnatureprogramsontheinternetWherecanyouseethem?inbooksonasnorkellingtripWatchthephotosandtrytowritedownthenameoftheanimalortheplantinyourexercisebooks.whitewhalesharkSeastar海星jellyfish水母Dolphin海豚Turtle海龟Coral珊瑚eel海鳗lobster龙虾shark鲨鱼Doyouknowaboutwhales?suchassharks鲨鱼thebaleenwhales须鲸thekillerwhales虎鲸Shark鲨鱼killerwhalesbaleenwhalesWhatdoyouthinkishappeninginthepicture?Killerwhalesareattackingabaleenwhalewithwhalerswaitingbyintheirboat,harpoonattheready.ReadingOldTomthekillerwhaleClancyAwhalerAnecdotesAtthebeginningforthe20thcenturyAustraliaThekillerwhalehelppeopletokillbaleenwhaleWriterVocationStyletimePlaceMainideaⅠ.Readthepassageandthenfillintheform1._________was16yearsofagewhenhewenttoworkatthewhalingstation.2._______orderedClancytogototheboatastherewasawhaleoutthereinthebay.3._______wasswimmingbytheboat,showingthewhalerstheway.ClancyOldTomGeorgeⅡ.Writedownnamesandknowwhattheydid?4._______toldClancythattheywouldreturnthenextdaytobringinthebodyofthewhale.5._______wascarriedbythewavesfurtherandfurtherawayfromthewhalers.6._______knewthatOldTomwouldprotectJames.JamesRedJackⅢ.Getthemainideasofthetwoanecdotes.Thefirstanecdotedescribesahuntingexperienceabouthowthekillerwhaleshelpedthewhalerstohuntawhale.ThesecondonetellsabouthowakillerwhaleprotectedandsavedJames,awhaler.Listentothetapeandanswerthefollowingquestions:OldTomthekillerwhale1.whatevidencewastherethatOldTomwashelpingoutthewhalers?2.whatotheranimalsdidtheauthorcomparethekillerwhaleswith?OldTomletthewhalersknowthattherewasabaleenwhalenearby;heshowedthemthewaytothewhaleDogs3.“Thekillersstartedracingbetweenourboatandthewhalejustlikeapackofexciteddogs.”whydoyouthinkthekillerwhalesbehavelikethis?Becausetheyknewthat,togetherwiththewhalers,theywouldsoonkillthebaleenwhaleandgetagoodmeal.4.whydidGeorgethinkthatthekillerwhalesworkedasateam?Becausehecouldseethatsomeofthekillerswerethrowingthemselvesontopofthewhale`sblowholewhileotherswerepreventingitfromfleeingouttosea.5.whydoyouthinkthewhalersallowedthekillerwhalestodragthewhaleunderthewatertofeedonitslipsandtongue?6.whydidthewhalersreturnhomewithoutthewhale’sbody?BecausetheyknewtheKillerWhaleswouldleavetherestofthebodytothemBecausethebodywouldnotfloattothesurfaceuntilabout24hourslaterWhyaretheanimalsundertheseabecomingfewerandfewer?Whatcanwedotoprotectthem?Possibleanswers:1.Reasons:(1)Livingpollutionandindustrialpollution(2)Humanhunting(3)Globalwarming(4)Themissingofthesea(5)Thekillerwhale2.Methods:(1)Stoppallingpollutingthingsintothesea(2)Plantmoretreesontheseashore(3)Protectenvironment(4)Increasethereproductionofseaanimals(5)Controlthenumberofthekillerwhale(6)Banhumanhunting(7)Arousepeople’sattentionByebye!
