阅读与完形(5)科技发明类本话题在新课标中涉及的内容很多，如医药进步、技术革新、科技发明、太空旅游、网络、传媒等，如2013山东卷阅读理解C篇，2013辽宁卷阅读理解C篇，2013福建卷阅读理解B篇等。3Dprintersareveryhottoday.Theyarebeingputtoallkindsofuses，rangingfromcreatingcarmodelsformoviestoarchitectural①models.However，noneoftheseideasareasshockingastheonesuggestedbyAnjanContractor，whobelievesthattheywillbethekeytoendingworldhunger.Accordingtosomeexperts，worldpopulationwillincreaseto10－12billionbytheendofthiscentury.Thismeansthatfoodwillbecomeveryexpensiveandpossibly，evenoutofreach，forbillionsofpeople.美文赏析Thisiswhere3Dprintingmaysavetheday.Anjanthinksthattheonlywaytosolvetheproblemwillbetoequipeverykitchenwitha3Dprinterandprintoutmealsfromtubesofpowderandoil.Hebelievesthatthesemealswithashelflifeofover30yearswouldresultinlessfoodwastage.Moreimportantly，itwouldbeeasiertomakefoodfromthingsthatwenowdonotconsideredible②.Agreatexampleofthatistheprotein③frommeat.Mostexpertsbelievethatasthepopulationgrows，thesupplyisnotgoingtobeenoughtofeedeveryone.Anjanbelievesthatwecouldeasilygetthesameproteinfrominsects.Thoughallthisfuturisticfoodmaysoundunappealing，thescientistsbelievethatwhenfacedwithaterriblefoodcrisis④，itwillbeverywelcomed.Whilethismaysoundalittledifficulttobelieve，AnjanseemstohaveconvincedthescientistsatNASA，whoarelookingforasolutiontofeedastronautswhentheygoonreallylongmissions⑤，liketheonebeingplannedtoMars.TheygaveAnjan$125,000tostartbuildingthefirstreal3Dprinterthatcreatesthefood.Anjanisnottheonlyonewiththisidea.AgroupledbyProfessorHodLipsonhasbeenexperimentingwiththisideasince2011andhasevensucceededinprintingoutcubeshapedcreationsfrompowderedmilkandcookieswithlimitedsugar!From：【解题导语】本文主要讲述了3D打印机是否能够“打印”食物。一、阅读与积累1．攻克疑难词汇①architecturaladj.建筑学的，建筑方面的②edibleadj.可食用的Thefoodatthehotelwasbarelyedible.那家旅馆的食物几乎无法食用。③proteinn．蛋白质④crisisn．危机⑤missionn．任务2．攻克疑难句Thoughallthisfuturisticfoodmaysoundunappealing，thescientistsbelievethatwhenfacedwithaterriblefoodcrisis,itwillbewelcomed.结构分析thoughallthisfuturisticfoodmaysoundunappealing是由though引导的让步状语从句；thescientists是主句的主语，谓语是believe；thatwhenfaced...是由连接词that引导的宾语从句，其中whenfacedwithaterriblefoodcrisis是宾语从句中的状语。尝试翻译虽然这种未来的食物听起来可能不吸引人，但科学家们认为当面临可怕的食物危机时，这种食物将受到欢迎。二、理解与尝试命题1．理解文章主旨Thepassagetalksaboutwhether3Dprinterswillbethekeytoendtheworldhunger.2．完形填空尝试命题文中画线词汇是完形填空命题中最易挖空的地方，请你和你的同桌依据句法常识自主写出三个干扰选项，并且比较一下谁的更符合高考的命题特点。①A.rangingB．________C．________D．________参考答案B．changingC．varyD．ranges②A.________B．________C．________D．that参考答案A．whatB．itC．with；which3．解题技巧点拨完形填空解题技巧之五：分析句法，多管齐下近几年的高考完形填空题中，虽然很少涉及语法知识，但是并不意味着不考查语法知识。对语法知识的考查往往是多方面的，为此，考生也要采用多种策略，多管齐下的方式来解题。对于难以把握的题目，不但要分析上下文逻辑关系，作者的写作目的与主旨，认真揣摩主人翁的态度，分析词法、句法功能，准确分析长难句等。[真题典例]1．(2013·陕西卷)Hecouldhavemadewhatwasalreadyanuncomfortablesituationworse，43(but)hechoseadifferentwayandgaveusareasontobelievethatthereisstill__44__inthisworld.I'llnever45(forget)hisactions.44．A.kindnessB．happinessC．politenessD．brightness答案A[全句意思是：他本来可以使原本就不好的情况变得更加糟糕，但他选择了一个不同的方式并且让我们有理由相信，在这个世界上依然存在着善。根据句意和全文的中心可知选项A符合语境kindness“善良”。happiness“幸福”，politeness“礼貌”，brightness“聪明”，不符合具体语境。]2．(2013·山东卷)．..Thatwasreallyabig44(step)forme.Bytheendoftheyear，Ihadseveralnewfriends，andtwoof__45__arestillmybestfriendstoday.45．A.usB．whichC．themD．whom答案C[注意and这个连词的作用，它说明两句之间是并列关系，从语法的角度分析此处不是定语从句，因此不用关系代词which或者whom，此处也不是谈论包括对方的情况，所以不用us。因此them符合题意。][学以致用](2013·广东卷)Numbersenseisnottheabilitytocount.Itistheabilitytorecognizeachangeinnumber...Itseemsthatnumbersenseissomethingwehaveincommonwithmanyanimalsinthisworld，andthatourhuman________isnotmuchbetterthanacrow's.A．sightB．natureC．abilityD．belief答案C[考查名词。“Itseemsthatnumber...thanacrow's.”是对全文的总结。根据第一段第一句和第二句不难得出答案。主题结构为Itseemsthat...句式，and后的that从句与第一个that从句并列。第一个从句中又含有一个定语从句修饰something，用于解释什么是数字感。]
