必修三Unit2Healthyeating教學(xué)設(shè)計(jì)與反思一、教學(xué)設(shè)計(jì)：（一）指導(dǎo)思想高中英語課程應(yīng)根據(jù)高中學(xué)生認(rèn)知特點(diǎn)和學(xué)習(xí)發(fā)展需要，在進(jìn)一步發(fā)展學(xué)生基本語言運(yùn)用能力的同時(shí)，著重提高學(xué)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(xué)生用英語進(jìn)行思維和表達(dá)的能力；為學(xué)生進(jìn)一步學(xué)習(xí)和發(fā)展創(chuàng)造必要的條件。高中英語課程的設(shè)計(jì)與實(shí)施有利于學(xué)生優(yōu)化英語學(xué)習(xí)方式，使他們通過觀察、體驗(yàn)、探究等積極主動(dòng)的學(xué)習(xí)方法，充分發(fā)揮自己的學(xué)習(xí)潛能，形成有效的學(xué)習(xí)策略，提高自主學(xué)習(xí)的能力。（二）學(xué)情分析飲食方面的話題是從實(shí)際出發(fā)、從自身體驗(yàn)出發(fā)的一個(gè)話題，學(xué)生應(yīng)該非常感興趣，而且就該話題讓學(xué)生做Reading,Talking和Discussion等活動(dòng)，學(xué)生們會(huì)有參與的熱情、會(huì)有發(fā)言的沖。Reading部分是一個(gè)故事性很強(qiáng)的敘事性文章，學(xué)生做起來并不會(huì)有太大的難度，而且Reading中富有戲劇性的變化讓學(xué)生可以從中感受故事的趣味性。（三）教學(xué)方法本單元的中心話題是“健康飲食”。通過單元教學(xué)讓學(xué)生了解飲食與健康方面的有關(guān)知識(shí)，并了解各種事物對(duì)人體的作用，引導(dǎo)學(xué)生關(guān)注平衡膳食，促使學(xué)生養(yǎng)成健康飲食的習(xí)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(dǎo)學(xué)生針對(duì)現(xiàn)實(shí)中遇到的實(shí)際問題發(fā)表自己的看法。通過合作式、探究式學(xué)習(xí)方式，激發(fā)學(xué)生的學(xué)習(xí)興趣，使學(xué)生由被動(dòng)變主動(dòng)，積極參與學(xué)習(xí)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(xué)目標(biāo)知識(shí)目標(biāo)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(biāo)1.Developstudents’readingabilityandletthemlearndifferentreadingskills.2.Enablestudentstotalkaboutdifferentkindsoffood,problemswithdietandbalanceddiet.情感目標(biāo)1.Stimulatestudents’sensetoformahealthyeatinghabit.2.Developstudents’senseofcooperativelearning.（六）教學(xué)重點(diǎn)與難點(diǎn)教學(xué)重點(diǎn)1.Letstudentslearnmoreaboutproblemswithadiet,abalanceddietandnutrition.2.Getstudentstolearndifferentreadingskills.教學(xué)難點(diǎn)1.Developstudents’readingability.2.Enablestudentstotalkaboutdifferentkindsoffoodandbalanceddiet.（七）教學(xué)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.ReadinganddiscussionReadthepassageathir
