nsumerswhoaredeliberatelyneglectedbyonlinecompanies.标准答案：F知识点解析：根据federalregulators和consumeradvocates定位到F段。本段主要讲解联邦监管人员和消费者权益保护者担忧电子分数可能会给某些消费者带来不利。题目概括了本段第1-2句，negativelyaffect对应原文的put…atadisadvantage；而deliberatelyneglected对应原文的bypassed。13、Thee-scoreisatypeofdigitalscorewhichmeasuresaconsumer’sbuyingpower.标准答案：B知识点解析：根据digitalscore和buyingpower定位到B段。结合上文可知，该段首句中的thesedigitalscores指代thee-score，本题句子的信息点与B段首句内容一致，B为本题答案。14、TheamountoffeeseBureauasksforrangesfromthreetoseventy-fivecentsperscore.标准答案：K知识点解析：根据threetoseventy-fivecents定位到K段。该段倒数第4句提到eBureau根据客户所在行业和提供的数据线索的数量来确定收费，每个分值3至75美分不等。本题句子表述与此一致。15、Thee-scoreisjustanotherindicationoftherisingScoredSociety.标准答案：P知识点解析：根据ScoredSociety定位到P段。从上文可知，该段第1句中的it指代e-score。题目中的indication与原文sign对应，rising对应原文theriseof，题目是对原文该句的同义转述。16、E-scoresdomuchmorethanevaluateconsumers’socioeconomicstatus.标准答案：D知识点解析：根据socioeconomicstatus定位到D段。文中提到，直营公司长期对消费者的社会经济地位排序，但电子商务走得更远，将消费者的职业、薪酬等诸多因素考虑在内。题目内容与该段第2、3句对应。17、AccordingtoastaffmemberofeBureau,thecompanyneithersellsconsumerdatanorkeepsthee-scoressenttoitsclients.标准答案：O知识点解析：根据consumerdata和clients定位到O段。题目是对该段第2句的同义转述，本题句子中的keep与原文retain对应，而sent对应原文的transmits。18、EBureaucitestheexampleofscoringpotentialcustomersforaprepaiddebitcardissuertoprovethatitse-scoremeasurementworks.标准答案：L知识点解析：根据题目中的aprepaiddebitcardissuer定位至L段。文中举例eBureau为一家预付借记卡发行商的潜在消费者进行排名，消费者的分值越高就越有可能带来高额利润。从而帮助客户选择潜在消费群体。eBureau网站借用这一典型案例，是为了说明其评定发挥了作用。题目概括了第2—3句的内容，题目中的scoringpotentialcustomers对应原文rankedprospectivecustomers。19、Thecalculationofthee-scoreinvolvesalargequantityofdataandreliesoncomputers.标准答案：C知识点解析：根据alargequantityofdata和computer定位至C段。该段第2句提到，与谷歌业务相类似，网络消费者得分涉及海量数据和复杂电脑运算。题目中的alargequantity与原文unimaginableamounts对应，relieson与原文poweredby对应。20、Thereisnoexistingfederallawthatgovernstheuseofe-scores.标准答案：H知识点解析：根据federallaw定位到H段。该段提到，企业必须通过合法的途径查询消费者信用记录，如果消费者因信用记录被拒绝申请信用卡或保险，则必须警告他们。但联邦法律的这些规定，尚未覆盖新出现的评估分值。题目内容来自该段第3句，题目中的noexistingfederallaws对应原文doesnotextendto。三、仔细阅读(本题共10题，每题1.0分，共10分。)Offeringagiftcanbeamutualpleasure;somemightsayitshouldbeapleasureforgiverandrecipient.AproblemwithamoderncommercialChristmas,however,isthatbuyinggiftscanbecomeachore.OftenitisastressriddenchoreinthedyingdaysbeforeChristmasDay,aseverythinggetslefttothelastminute.WhynotmakethisnextChristmasatimetomakethechoosingofindividualgiftsapleasureforyourself,andfortherecipient?OfteninthelastminutehastetobuygiftsintimeforChristmasDay,peoplebecomedetachedfromnotonlythepurpose,butthepersontowhomtheyaregiving.Boughthastilyinacrowdedstressfilledstore,scarcelyathoughtmaypassfortheindividualonthereceivingend,howeverclosetheymaybetoyou.Mostoftheyear,ifnotall,canbefilledwithwork,commuting,rushinghereandthere,stress,andselffocus.Howabouttimeandattentionforthosewhoreallymatterinyourlife,whetherspouse,offspring,otherrelatives,friendsorcolleagues?Thechoosingofagift,andpresentationofit,canbeasilentwayofgivingeachofthemspecialattention,andthenculminatingwiththeirpleasureatthereceiptofthegift.Behindeverygoodpresentthereisapersonwhoworkedhardtomakethebestchoice.Thesecrettobuyingtheperfectgiftistothinkaboutthemessageyouwanttosendout,whenthereceiveropensit.Ifyouthinkabouthisorherhobbies,tohisorhervacationplansetc.,itmeansyouhavereallystudiedthatpersonandyouboughtthepresentpreciselyforthem,forthatoccasion;inthiscase,Christmas.Friendshipandcaringarethemselvesagift,soyoucanseethatifyouputsomerealselflesseffortintochoosinggifts,thevalueofthegiftismagnified.Thatissomethingwhichwillshinethroughthewrappingpaper,andinthemomentofgivingthepleasurethatyoufeelinmakingthegesturewillradiateinthewarmthofyourexpression.Thechoosingandthegivingofagiftareinseparable.21、WhatmakesbuyinggiftsforChristmasbecomeachore?A、Thepressureoftheholiday.B、Thelackoftimeforshopping.C、Theincreasingvarietyofgifts.D、Thecommercializationoftheholiday.标准答案：B知识点解析：首段末句中的dyingdays和lastminute都表明是时间上的因素使圣诞节的购物变成苦差事，因此本题应选B。22、Whenbuyinggiftsinthelastminute,peopletendtobeconcernedabout______.A、choosingindividualgiftsfortherecipientsB、whatisthemoresuitablegiftforaholidayC、gettingagiftforeveryoneD、towhomtheysendthegift标准答案：C知识点解析：第2段第2句中的detachedfrom…表明在最后一刻才急匆匆地赶去买礼物时，人们不考虑礼物的目的，不考虑送礼的对象，当然也就不会考虑礼物是否合适，也就是说，人们只是为了买礼物而买礼物，只想给每个人送礼，由此可见，本题应选C。23、Aperfectgiftdiffersfromothergiftsintheir______.A、usefulnessB、meaningfulnessC、exquisitenessD、artistry标准答案：B知识点解析：第4段第2句中的message一词表明完美礼物注重的是礼物表达的信息，即其含义，因此本题应选B。24、The"gesture"(Line3,Para.5)mostprobablyrefersto______.A、givingthegifttotherecipientB、choosingagiftwithselflesseffortC、wrappingthegiftbeforesendingitD、showingyourconcerntotherecipient标准答案：A知识点解析：本题解题的关键在于理解末段第2句中的第2个分句。在这个分句中，thepleasure是主语，willradiate…是谓语，pleasure后that引出的是修饰pleasure的定语从句，这样就不难看出gesture是指该分句开头的giving，由此可见，本题应选A。25、Inthispassage,theauthorismostlikelytopointout______.A、thebestwayofchoosingandgivingtherightgiftsB、theimportanceofthoughtfulnessinchoosingagiftC、thatone’sloveforotherscanbestbedemonstratedbygiftsD、thatofferingagiftbenefitsboththegiverandthereceiver标准答案：D知识点解析：本文在首段首句、第2段首句、第3段末句，以及末段第2句不断强调“赠送礼物时对赠送者和接受者而言都是一种快乐”这个主题，由此可见，本
