B．Dosportsoutside.C．Smokeoccasionally. D．Apositiveattitude.解析：根据第二段中“...thinkspositively”可知，健康的人乐观地思考。故选D。2．Whichisnotthebenefitofahealthylifestyle?CA．Dealingwithstresses.B．Improvingqualityoflife.C．Havingsharpmind.D．Reducingtheimpactofhealthproblems.解析：根据WhyIsItImportant？部分可知C.(思维敏捷。)不是文章中所陈述的健康生活方式的好处。故选C。3．Whatcanweinferfromthepassage?AA．Whatyoudothroughoutthedaydecidesyourhealth.B．Takeahealthstepeverydayintwomonthsandyouwillbeamongthehealthiestperson.C．Itistoolatetolivehealthilyatanoldage.D．Itishardtomakeachangetoyourdailylife.解析：根据GoodHealthIs“Simple—ButIt'sNotEasy”部分第二句“Yourhealthdependsonwhatyoudothroughouttheday,everyday.(你的健康取决于你每天所做的事情。)”可知，A项正确。根据该部分最后一句可知B项错误和CanYouAdoptaHealthyLifestyle？部分(无论你的年龄、健康水平或体型如何，开始考虑健康生活永远不会太早或太晚。从现在开始改变你的日常生活，你就可以向健康生活迈出一步。那也不难，对吧？)可知C、D项错误。故选A。外出就餐、点外卖已经成为当代年轻人生活的一部分，然而许多深受消费者喜爱的食物中常常含有大量的油脂、盐、糖，且它们往往是高热量食物。这些食物是造成一些慢性疾病(如高血压、糖尿病、脂肪肝等)年轻化的主要因素。同时，缺乏必要的身体锻炼也加速了慢性疾病在年轻群体中的发作。TheNationalHealthCommissionofthePeople'sRepublicofChinarecentlyissuedareportonnutritioninwhichitwarnsthatmorethanhalfoftheadults,andnearly20percentofthoseagedbetween6and17inthecountryareoverweightorobese,andchronicdiseases,suchashighbloodpressure,diabetesandfattyliver,arebecomingpublichealththreats.Diningout,orderingtakeoutonline,andsnackingarepartofmodernlifestyle,whilethefactisthatsuchtypesoffoodscanoftenbehighincalories,fat,saltandsugar.Theuseofconvenientelectricandelectronicdevices,withasharpdeclineinallmajortypesofphysicalactivities,isanotherfactorleadingtopoorhealth.SectionⅠReadingandThinking课文预读Ⅰ.快读文章，把握大意1．Part1(Para.1)
