必修三 Unit 2 Healthy eating 教學設(shè)計與反思

必修三Unit2Healthyeating教學設(shè)計與反思一、教學設(shè)計：（一）指導思想高中英語課程應(yīng)根據(jù)高中學生認知特點和學習發(fā)展需要，在進一步發(fā)展學生基本語言運用能力的同時，著重提高學生用英語獲取信息、處理信息、分析和解決問題的能力；逐步培養(yǎng)學生用英語進行思維和表達的能力；為學生進一步學習和發(fā)展創(chuàng)造必要的條件。高中英語課程的設(shè)計與實施有利于學生優(yōu)化英語學習方式，使他們通過觀察、體驗、探究等積極主動的學習方法，充分發(fā)揮自己的學習潛能，形成有效的學習策略，提高自主學習的能力。（二）學情分析飲食方面的話題是從實際出發(fā)、從自身體驗出發(fā)的一個話題，學生應(yīng)該非常感興趣，而且就該話題讓學生做Reading,Talking和Discussion等活動，學生們會有參與的熱情、會有發(fā)言的沖。Reading部分是一個故事性很強的敘事性文章，學生做起來并不會有太大的難度，而且Reading中富有戲劇性的變化讓學生可以從中感受故事的趣味性。（三）教學方法本單元的中心話題是“健康飲食”。通過單元教學讓學生了解飲食與健康方面的有關(guān)知識，并了解各種事物對人體的作用，引導學生關(guān)注平衡膳食，促使學生養(yǎng)成健康飲食的習慣并能在生活中改善飲食結(jié)構(gòu)，豐富飲食文化，從而保持身體健康。另外，要引導學生針對現(xiàn)實中遇到的實際問題發(fā)表自己的看法。通過合作式、探究式學習方式，激發(fā)學生的學習興趣，使學生由被動變主動，積極參與學習過程。（四）教材分析1.WarmingUpistotellstudentshowdifferentkindsoffoodaregrouped.Thisisimportantasitenablesustotalkaboutthevalueofparticularfoodstoourhealth.Wewantstudentstoappreciatewhatabalanceddietis.Theteachercanhaveafreetalkwithstudents,letthemworkinpairstoreadthroughthechartanddiscussthequestions.2.Pre-readingcontainstwomoregeneralquestionsaboutfoodfordiscussion.Studentscanbeencouragedtodiscussthesequestionsinpairs.Thentheyareaskedtolookatthetitleofthereadingpassageandthepicturestopredictwhatthepassageisabout.ThispartisveryusefulforthenextpartReading.3.ThereadingpassageComeandEatHereintroducesstudentstotwounbalanceddietsthroughtherestaurantsofWangPengandYongHui.FoodatWangPeng’srestaurantcontainstoomuchfatwhileYongHui’srestaurantofferslittleenergy-givingfood.Afterreading,studentsarerequiredtodotheexercisesinComprehendingtoseehowmuchtheyhaveunderstoodthereadingpassage.Theteachercanletthemworkinpairsoringroupstofindtheanswerscooperatively,andthenchecktheiranswerswiththewholeclass.（五）教學目標知識目標1.Getstudentstolearntheusefulnewwordsandexpressionsinthispart:diet,nut,bean,pea,cucumber,eggplant,pepper,mushroom,peach,lemon,balance,barbecue,mutton,roast,fry,ought,bacon,slim,curiosity,hostess,raw,vinegar,liebalanceddiet,oughtto,loseweight,getawaywith,tellalie,win...back2.Letstudentslearntheknowledgeofbalanceddietandnutrition.能力目標1.Developstudents’readingabilityandletthemlearndifferentreadingskills.2.Enablestudentstotalkaboutdifferentkindsoffood,problemswithdietandbalanceddiet.情感目標1.Stimulatestudents’sensetoformahealthyeatinghabit.2.Developstudents’senseofcooperativelearning.（六）教學重點與難點教學重點1.Letstudentslearnmoreaboutproblemswithadiet,abalanceddietandnutrition.2.Getstudentstolearndifferentreadingskills.教學難點1.Developstudents’readingability.2.Enablestudentstotalkaboutdifferentkindsoffoodandbalanceddiet.（七）教學過程→Step1Leading-inHaveafreetalkwithstudents.Askthemthefollowingquestions:1.Everybodyhastoeat,butdoyoueatahealthydiet?2.Whatdoyouusuallyhaveforbreakfast/lunch/supper?3.Whatkindoffooddoyoulikebest?4.Whyareyousostrong/weak/fat/thin?Doesithaveanythingtodowithyourdiet?5.Doyouthinkyouareeatingabalanceddiet?→Step2Warmingup1.LetstudentsturntoPage9.Askthemtolookatthepictures,namethefoodsinthemandthenfillintheform.HealthyfoodUnhealthyfood2.Doyouknowthatthefoodyoueathelpsyougrowindifferentways?Foodthatprovidesenergy(e.g.energy-givingfood)Foodthathelpsgrowbonesandmuscles(e.g.body-buildingfood)Foodthathelpsthebodyfightdiseases(e.g.protectivefood)ricenoodlesspaghettibreadpotatoeschocolatebuttercreamoilsnutsmeateggscheesemilktofuMostvegetables(e.g.beans,peas,cucumbers,eggplants,peppers,mushrooms,cabbages)andfruit(e.g.apples,peaches,oranges,lemons)→Step3Pre-readingLetstudentsturntoPage10,lookatthetitleofthereadingpassageandthepicturesandpredictwhatthepassageisabout.Thenhavethemreadthepassagequicklytoseeiftheyareright.→Step4Reading1.FastreadingAskstudentstoskimthereadingpassageandthenanswerthefollowingquestions:1)Whoarementionedinthestory?2)Wheredidthestoryhappen?Threeminuteslater,checktheanswerswiththewholeclass.Suggestedanswers:1)WangPeng,YongHuiandLiChang.2)Ithappenedinthetworestaurants:WangPeng’srestaurantandYongHui’srestaurant.2.IntensivereadingAllowstudentstoreadthepassagecarefullythistimetounderstandthemainideaofeachparagraphandtheimportantdetails,andthenfinishthefollowing:1)Usetheinformationfromthereadingpassagetotickoutthecorrectstatementsandgivereasonsforyouranswers.(1)UsuallyWangPeng’srestaurantwasfullofpeople.(2)YongHuicouldmakepeoplethinintwoweeksbygivingthemagooddiet.(3)WangPeng’sregularcustomersoftenbecomefat.(4)YongHui’smenugavecustomersmoreenergy-givingfood.(5)WangPeng’smenugavecustomersmoreprotectivefood.(6)WangPengdecidedtocompetewithYongHuibycopyinghermenu.2)Thepassagecanbedividedinto3parts.Givethemainideaineachpart.PartMainideaPart1Part2Part33.ReadinganddiscussionReadthepassageathirdtimeandthenworkinpairstodothefollowing:1)Writeoutyouranswers.(1)TheweaknessofthedietinWangPeng’srestaurantwasthatitdidnotgive______________.(2)ThestrengthofthedietinWangPeng’srestaurantwasthatitprovided______________.(3)TheweaknessofthedietinYongHui’srestaurantwasthatitdidnotgive______________.(4)ThestrengthofthedietinYongHui’srestaurantwasthatitprovided______________.4.ExplanationHelpstudentsanalyzesomedifficult,longandcomplexsentencesandgues
