Learninggoalsfood&drinkscabbageoniontomatobananaapplefishice-creamcoffeecolahamburgerBrainstormWarmingupArethesehealthyorunhealthy?healthyfoodanddrinkArethesefoodanddrinkshealthyorunhealthy?junkfood/drinkunhealthyfood/drinkjunkfood的说法来自于葡萄牙语。大约500年前，在葡萄牙语里有一个词“junk”，意思是“oldpiecesofrope（旧缆绳）”。后来这个词的意思逐渐演变为任何可利用的废弃材料。最后，“junk”用来指价值不高或根本没有任何价值的东西。于是，人们就称没有多少营养的食物为“junkfood”。junkfood—Howoftendoyoudrink/eat...?—Idrink/eat...everyday/onceaweek/...Ineverdrink/eat...Ioften/sometimes/usuallydrink/eat...FreetalkHowshouldwekeepahealthylife?ahealthydietexercisesleepwellkeeponeselfcleankeepanoptimistic(乐观的)mind...Discussion1.bjunkfood3.____fruit 5.____sleep2.____milk 4.____vegetables 6.____coffee1aMatchthewordswiththepictures.abcdefaecfdn.咖啡HealthylifeUnhealthylife1.Whatdoyouusuallyeatordrink?2.Whatshouldwedrinkoreateveryday?3.Whatshouldwehardlyeverornevereat?4.Doyoudrinkcoffee?Why?5.Arehamburgersgoodforourhealth?Howaboutfruit?Why?Talkaboutthefollowingquestionswithyourpartner.1bAskandanswerquestions.Usethewordsfrom1a.A:Howoftendoyoudrinkmilk,LiuFang?B:Idrinkmilkeveryday.A:Doyoulikeit?B:No.Butmymotherwantsmetodrinkit.Shesaysit’sgoodformyhealth.对······有好处1.Shesaysit’sgoodformyhealth.(教材P121b)（1）begoodfor为固定短语，后可接名词、代词或动词-ing，意为“对······有好处”，其反义短语为bebadfor，意为“对······有害”。
