解析]根据题干中的mergersandacquisitions定位到第1段。C中的unprecedentedforce与该段第2句的内容相近，故为本题答案。A中的warmlywelcome缺乏原文依据；第1句中的thebiggest表明这一次合并潮只是“最大的一次”，这也就暗示合并潮以前就出现过，可见，D不正确。(2).TheauthorcitedthemultinationalsinArgentinainorderto______.（分数：2.00）A.arouseconcernoverthestabilityoftheworldeconomyB.criticizetheoveremphasisonthedevelopmentofmultinationalsC.beacontrasttotheinsufficientconcernaboutsmallernationalfirmsD.illustratetheincreasingimportanceofmultinationalsininternationaltrades√解析：[解析]根据题干中的multinationalsinArgentina定位到第2段第5句。在该句中提到的Argentina的情况是为了说明该段前几句的观点：跨国公司生意越做越大。地位越来越重要，将四个选项的内容与此对比，可发现D意思最相近，故为本题答案。(3).Theforcesbehindthewaveofmergersandacquisitionswillresultin______.（分数：2.00）A.enhancedmarketsB.lowertradecostC.theunderminedofglobalizationD.advantagestocustomers√解析：[解析]第3段第2句开头的Allthese指的是该段第1句的forces。可见，第2句表明这些forces对消费者是有利的，因此，本题应选D。A和B是第1句冒号后的内容，在原文中，冒号后列举了各种forces。可见，A和B是forces本身，而非forces带来的结果。C中的undermine与原文中的underlie意思完全不同。(4).WhatdidtheU.S.fearnearlyacenturyago?（分数：2.00）A.Thethreatstocompetition.√B.Thethreatstotheoilmarket.C.Themergerofafewoilfirms.D.Thecompetitionintheoilmarket.解析：[解析]在第4段第2句中，定语从句thatwerefeared...中的that应该指前面的先行词threats，。A的所指。就不难确定本题应选that形成主谓一致，找到were这样才能与从句的动词(5).Inthelastparagraph,theauthormostprobablyagreesthat______.（分数：2.00）A.megabankingmergerswillnotappearbecauseofGreenspanswarningB.multinationalsalwaystrytoavoidviolatingfaircompetitionC.theattitudetowardsunfaircompetitionvariesfromnationtonation√D.theU.S.shouldnhavesuedMicrosoftforunfaircompetition解析：[解析]最后一段第4句表明在现实中各国对违反公平竞争的处理力度不一，即表明各国对不合理竞争的做法态度不相同，可见，本题应选C。该段第2句提到了Greenspan的警告，银行业是不是会因为他的警告就不会合并?原文并没有就此给出答案，可见，A说得过于绝对。第4句表明有些跨国公司可能离开对不公平竞争严格监管的国家/地区，转而到别的地区去做生意，这恰恰表明这些跨国公司不愿遵守公平竞争的做法，可见，B与原文的推论相反；最后一句表明美国出于“保护公平竞争”而起诉了微软公司，而作者很可能认为别的国家也应向美国学习这种做法，可见，作者应该不会认同D的说法。Theregularuseoftextmessagesande-mailscanlowertheIQmorethantwiceasmuchassmokingmarijuana.Thatistheclaimofpsychologistswhohavefoundthattappingawayonamobilephoneorcomputerkeypadorcheckingthemforelectronicmessagestemporarilyknocksupto10pointsofftheusersIQ.Thisrateofdeclineinintelligencecomparesunfavorablywiththefour-pointdropinIQassociatedwithsmokingmarijuana,accordingtoBritishresearchers,whohavelabeledthefleetingphenomenonofenhancedstupidityasinfomania.ResearchonsleepdeprivationsuggeststhattheIQdropcausedbyelectronicobsessionisalsoequivalenttoawakefulnight.Infomaniaismainlyaproblemforadultworkers,especiallymen,thestudycommissionedbyHewlettPackard,thetechnologycompany,hasconcluded.ThenoticeabledropinIQisattributedtotheconstantdistractionofalwaysontechnologywhenemployeesshouldbeconcentratingonwhattheyarepaidtodo.Infomaniameansthattheyloseconcentrationastheirmindsremainfixedinanalmostpermanentstateofreadinesstoreacttotechnologyinsteadoffocusingonthetaskinhand.Thebrainalsofindsithardtocopewithjugglinglotsoftasksatonce,reducingitsoveralleffectiveness,thereportadded.Andwhilemodemtechnologycanhavehugebenefits,excessiveusecanbedamagingnotonlytoapersonsmind,buttotheirsociallife.EightyvolunteerstookpartinclinicaltrialsonIQdeteriorationand1,100adultswereinterviewed.Morethansixinten(62percent)ofpeoplepolledadmitthattheywereaddictedtocheckingtheire-mailsandtextmessagessooftenthattheyscrutinizedwork-relatedonesevenwhenathomeoronholiday.Halfsaidthattheyalwaysrespondedimmediatelytoanemailandoneinfive(21percent)willinterruptameetingtodoso.Furthermore,infomaniaishavinganegativeeffectonworkcolleagues,increasingstressanddissentingfeelings.Nineoutoftenpolledthoughtthatcolleagueswhoanswerede-mailsormessagesduringaface-to-facemeetingwereextremelyrude.YetoneinthreeBritonsbelievesthatitisnotonlyacceptable,butactuallydiligentandefficienttodoso.（分数：10.00）(1).Accordingtothepassage,infomaniatendsto______.（分数：2.00）A.becausedbyadeclineinintelligenceB.leaveapermanentinfluenceononesIQC.becausedbyelectronicobsession√D.resultinonessleepdeprivation解析：[解析]根据题干中的infomania定位到第2段。对比第2段和第3段中可知infomania与theIQdrop同义，第3段theIQdrop后的定语causedbyelectronicobsession表明infomania就是由electronicobsession引起的，因此，C正确。infomania和A中的adeclineinintelligence为相同的概念，两者不可能构成因果关系；B中的permanent一词缺乏原文依据；根据原文，D提到的sleepdeprivation与同样为导致智力下降的原因，而它们之间的因果关系也缺乏原文依据。infomanian(2).Toinitiatethestudy,HewlettPackardsresearchismostprobablyabout______.（分数：2.00）A.therelevancebetweenonesIQandhisuseoftechnology√B.theinfluenceoftechnologyononesdeclineinintelligenceC.thedifferentdamagetoourbraindonebytechnologyandunhealthyhabitsD.therelationshipbetweenonesintelligenceandhisworkingeffectiveness解析：[解析]根据题干中的HewlettPackard定位到第4段。要正确回答本题，就要先正确理解问题。问题中的toinitiatethestudy应理解为HewlettPackard最开始要研究的主题是什么?总结前四段可知HewlettPackard公司的研究“结果”可用B来表述，这应该是在研究“科技”与“IQ”之间的关系时得出的结论。在开始研究的时候，HewlettPackard并不知道科技会导致IQ下降。可见，在A和B之间，A为研究主题，为本题答案，而B是经过研究主题后所得的结论，不符合题意。(3).Infomaniaemployeesaremorereadytoreacttotechnologythanthetasksinhandbecause______.（分数：2.00）A.thetaskscanbedonewithouttechnologyB.technologyisconvenientlyavailable√C.thetasksaretechnologicallydiverseD.technologycanhelplessenworkpressure解析：[解析]根据题干中的employees定位到第5段。B中的convenientlyavailable与第5段第1句中的alwayson为同义改写；其他选项虽然在现
