.C细节理解题。根据第五段第二句中“thosepeopleforwhomtheroleofvolunteerwasmostpartoftheirpersonalidentitywouldalsobemostlikelytocontinuevolunteerwork”可知志愿者身份认同会激励他们继续从事志愿者工作。故选C项。64.A标题归纳题。文章首段提出假设：假如你是一名组织领导人，很想得到志愿者的帮助。并指出在此之前，必须弄清志愿者为什么自发地去服务社会，并通过3个实验研究志愿者的意图。因此A项（如何使人们从事志愿者服务）是文章的最佳标题。【考点定位】议论文阅读【名师点睛】议论说理类文章具有以下特点：1．一般按提出问题、分析问题、解决问题的方法写作。作者一般从日常生活中的热点问题、社会上的重大问题、与读者息息相关的问题入手，即提出问题。然后，分析利弊，举例说明，推理判断，即分析问题。最后，阐述观点，提出办法，即解决问题。2．以作者的观点或情感为核心，对细节推理等方面进行考查。3．文章的主题一般是生活中的热点问题、重大问题或与生活息息相关的问题等。考生应注意抓住作者提出的观点、给出的例证及最后得出的结论。同时，理清作为论据的诸多事例和理由之间以及它们和观点/结论之间的内在联系，把握文章的结构。5.【2015·广东】CDanielAnderson,afamouspsychologist,believesit’simportanttodistinguishtelevision’sinfluencesonchildrenfromthoseofthefamily.WetendtoblameTV,hesays,forproblemsitdoesn’treallycause,overlookingourownrolesinshapingchildren’sminds.Onetraditionalbeliefabouttelevisionisthatitreducesachild’sabilitytothinkandtounderstandtheworld.WhilewatchingTV,childrendonotmerelyabsorbwordsandimages(影像).Instead,theylearnbothexplicitandhiddenmeaningsfromwhattheysee.Actually,childrenlearnearlythepsychologyofcharactersinTVshows.Furthermore,asmanyteachersagree,childrenunderstandfarmorewhenparentswatchTVwiththem,explainingnewwordsandideas.Yet,mostparentsuseaneducationalprogramasachancetoparktheirkidsinfrontofthesetanddosomethinginanotherroom.Anotherargumentagainsttelevisionisthatitreplacesreadingasaformofentertainment.ButaccordingtoAnderson,theamountoftimespentwatchingtelevisionisnotrelatedtoreadingability.TVdoesn’ttaketheplaceofreadingformostchildren;ittakestheplaceofsimilarsortsofrecreation,suchaslisteningtotheradioandplayingsports.Thingslikeparents’educationalbackgroundhaveastrongerinfluenceonachild’sreading.“Achild’sreadingabilityisbestpredictedbyhowmuchaparentreads.”Andersonsays.Traditionalwisdomalsohasitthatheavytelevision-watchinglowersIQ(智商)scoresandaffectsschoolperformance.Buthere,too,Andersonnotesthatnostudieshaveprovedit.Infact,researchsuggeststhatit’stheotherwayaround.“Ifyou’resmartyoung,you’llwatchlessTVwhenyou’reolder,”Andersonsays.Yet,peopleoflowerIQtendtobelifelongtelevisionviewers.Foryearsresearchershaveattemptedtoshowthattelevisionisdangeroustochildren.However,byshowingthattelevisionpromotesnoneofthedangerouseffectsasconventionallybelieved,Andersonsuggeststhattelevisioncannotbecondemnedwithoutconsideringotherinfluences.36.BywatchingTV,childrenlearn_________.A.imagesthroughwordsB.morethanexplicitmeaningsC.moreaboutimagesthanwordsD.littleaboutpeople’spsychology37.Aneducationalprogramisbestwatchedbyachild_________.A.onhisownB.withotherkidsC.withhisparentsD.withhisteachers38.Whichofthefollowingismostrelatedtochildren’sreadingability?A.Radio-listeningB.Television-watchingC.Parents’readinglistD.Parents’educationalbackground39.Andersonbelievedthat_________.A.themoreachildwatchesTV,thesmarterheisB.theyoungerachildis,themorehewatchesTVC.thesmarterachildis,thelesslikelyhegetsaddictedtoTVD.thelessachildwatchesTV,thebetterheperformsatschool40.Whatisthemainpurposeofthepassage?A.ToadviseontheeducationaluseofTV.B.TodescribeTV’sharmfuleffectsonchildren.C.ToexplaintraditionalviewsonTVinfluences.D.TopresentAnderson’sunconventionalideas.【解析】试题分析：本文叙述著名心理学家DanielAnderson对孩子们看电视的看法，打破了以往人们认为看电视对孩子不好的想法。他认为孩子们看电视不知学到显现出来的东西；父母陪孩子看电视，孩子可以学到更多知识；孩子看电视并没有代替孩子阅读，并没有影响孩子的智商。36.B细节理解题。根据第二段的Instead,theylearnbothexplicitandhiddenmeaningsfromwhattheysee.可知孩子们通过看电视，可以学到显性和隐藏的意义，因此不仅仅学到隐藏的意思。故选B。37.C推理判断题。根据第二段的Furthermore,asmanyteachersagree,childrenunderstandfarmorewhenparentswatchTVwiththem“孩子们有父母陪着看电视理解的更多”，故推断教育节目最好是父母陪着孩子看。故选C。38.D细节理解题。根据第三段的Thingslikeparents’educationalbackgroundhaveastrongerinfluenceonachild’sreading.可知父母的教育背景对孩子的阅读有很强的影响。故选D。39.C细节理解题。根据第四段的“Ifyou’resmartyoung,you’llwatchlessTVwhenyou’reolder”可知如果你小时越聪明，长大看电视看得越来越少。故选C。40.D推理判断题。根据最后一段的Andersonsuggeststhattelevisioncannotcondemnedwithoutconsideringotherinfluences.“Anderson认为不应该按照常规，不考虑电视的其他影响而去谴责电视”故推断这篇文章的目的是呈现Anderson打破常规的想法，故选D。【考点定位】教育类短文阅读。【名师点睛】本文侧重考查学生的细节理解能力。问题设置巧妙，根据题干要求，学生自己阅读，就能在文中找到答案。尤其第40题，充分考查了学生的语篇理解能力。同时，这篇短文提出的一种与常规不一样的看法，看电视对孩子是有好处的。6.【2015·陕西】CTheproductionofcoffeebeansisahuge,profitablebusiness,but,unfortunately,full-sunproductionistakingovertheindustryandbringingaboutalotofdamage.Thechangeinhowcoffeeisgrownfromshade-grownproductiontofull-sunproductionendangerstheveryexistenceof,certainanimalsandbirds,andevendisturbstheworld’secologicalbalance.Onalocallevel,thedamageoftheforestrequiredbyfull-sunfieldsaffectsthearea’sbirdsandanimals.Theshadeoftheforesttreesprovidesahomeforbirdsandotherspecial(物种)thatdependonthetrees’flowersandfruits.Full-suncoffeegrowersdestroythisforesthome.Asaresult,manyspecialarequicklydyingout.Onamoregloballevel,thedestructionoftherainforestforfull-suncoffeefieldsalsothreatens(威胁)humanlife.Medicalresearchoftenmakesuseoftheforests'plantandanimallife,andthedestructionofsuchspeciescouldpreventresearchersfromfindingcuresforcertaindiseases.Inaddition,newcoffee-growingtechniquesarepoisoningthewaterlocally,andeventuallytheworld'sgroundwater.Bothlocallyandglobally,thecontinuedspreadofful
