的成功中可以得出，尝试新事物是值得的。故选A项。14.（2020·浙江卷）CChallengingworkthatrequireslotsofanalyticalthinking,planningandothermanagerialskillsmighthelpyourbrainstaysharpasyouage,astudypublishedWednesdayinthejournalNeurologysuggests.ResearchersfromtheUniversityofLeipziginGermanygatheredmorethan1,000retiredworkerswhowereoverage75andassessedthevolunteers’memoryandthinkingskillsthroughabatteryoftests.Then,foreightyears,thescientistsaskedthesamegrouptocomebacktothelabevery18monthstotakethesamesortsoftests.Thosewhohadheldmentallystimulating(刺激),demandingjobsbeforeretirementtendedtodothebestonthetests.Andtheytendedtolosecognitive(认知)functionatamuchslowerratethanthosewiththeleastmentallychallengingjobs.Theresultsheldtrueevenafterthescientistsaccountedfortheparticipants’overallhealthstatus.“Thisworksjustlikephysicalexercise,”saysFranciscaThen,wholedthestudy.“Afteralongrun,youmayfeellikeyou’reinpain,youmayfeeltired.Butitmakesyoufit.Afteralongdayatwork-sure,youwillfeeltired,butitcanhelpyourbrainstayhealthy.”It'snotjustcorporatejobs,orevenpaidworkthatcanhelpkeepyourbrainfit,Thenpointsout.Awaiter’sjob,forexample,thatrequiresmultitasking,teamworkanddecision-makingcouldbejustasstimulatingasanyhigh-levelofficework.And“runningafamilyhouseholdrequireshigh-levelplanningandcoordinating(协调),”shesays.“Youhavetoorganizetheactivitiesofthechildrenandtakecareofthebillsandgroceries.”Ofcourse,ourbrainscandeclineaswegrowolderforlotsofreasons-includingotherenvironmentalinfluencesorgeneticfactors.Still,continuingtochallengeyourselfmentallyandkeepingyourmindbusycanonly,优点英语help.28.Whydidthescientistsaskthevolunteerstotakethetests?A.Toassesstheirhealthstatus.B.Toevaluatetheirworkhabits.C.Toanalyzetheirpersonality.D.Tomeasuretheirmentalability.29.HowdoesFranciscaThenexplainherfindingsinparagraph4?A.Byusinganexpert’swords.B.Bymakingacomparison.C.Byreferringtoanotherstudy.D.Byintroducingaconcept.30.Whichofthefollowingisthebesttitleforthetext?A.RetiredWorkersCanPickUpNewSkillsB.OldPeopleShouldTakeChallengingJobsC.YourToughJobMightHelpKeepYouSharpD.CognitiveFunctionMayDeclineAsYouAge【答案】28.D29.B30.C【解析】这是一篇说明文。《神经病学》杂志发布的一则研究显示，需要大量的分析思考、细致规划和其他管理技能有挑战性的工作，有可能会帮助你的大脑随着年龄的增长而保持敏锐。28.细节理解题。根据第二段第一句“ResearchersfromtheUniversityofLeipziginGermanygatheredmorethan1,000retiredworkerswhowereoverage75andassessedthevolunteers’memoryandthinkingskillsthroughabatteryoftests.(来自德国莱比锡大学的研究人员召集了1000多名75岁以上的退休老人，并通过一系列的测试对他们的记忆力和思维能力进行了评估。)”可知，科学家让志愿者做测试是为了测试他们的心智能力。故选D项。29.推理判断题。根据第四段中FranciscaThen说的话“Thisworksjustlikephysicalexercise,(这就像体育锻炼一样有效。)”及接下来进一步的解释“长跑后人就会感到痛苦和疲惫，但它确实能强身健体。工作一天下来会感到劳累，但这也使你的大脑处于健康状态”可知，FranciscaThen是通过与“身体锻炼”作比较来解释他的发现的。故选B项。30.主旨大意题。第一段“Challengingworkthatrequireslotsofanalyticalthinking,planningandothermanagerialskillsmighthelpyourbrainstaysharpasyouage(需要大量的分析思考、细致规划和其他管理技能有挑战性的工作，有可能会帮助你的大脑随着年龄的增长而保持敏锐。)”是本文的主题句，结合全文内容可知，文章主要讲述了有挑战性的工作可能会使大脑保持敏捷，所以C项“困难的工作可能有助于大脑保持敏捷”适合作本文标题。故选C项。,优点英语【2019年】1.【2019·全国卷I，C】Asdataandidentitytheftbecomesmoreandmorecommon,themarketisgrowingforbiometric(生物测量)technologies—likefingerprintscans—tokeepothersoutofprivatee-spaces.Atpresent,thesetechnologiesarestillexpensive,though.ResearchersfromGeorgiaTechsaythattheyhavecomeupwithalow-costdevice(装置)thatgetsaroundthisproblem:asmartkeyboard.Thissmartkeyboardpreciselymeasuresthecadence(节奏)withwhichonetypesandthepressurefingersapplytoeachkey.Thekeyboardcouldofferastronglayerofsecuritybyanalyzingthingsliketheforceofauser'stypingandthetimebetweenkeypresses.Thesepatternsareuniquetoeachperson.Thus,thekeyboardcandeterminepeople'sidentities,andbyextension,whethertheyshouldbegivenaccesstothecomputerit'sconnectedto—regardlessofwhethersomeonegetsthepasswordright.Italsodoesn'trequireanewtypeoftechnologythatpeoplearen'talreadyfamiliarwith.Everybodyusesakeyboardandeverybodytypesdifferently.Inastudydescribingthetechnology,theresearchershad100volunteerstypetheword“touch”fourtimesusingthesmartkeyboard.Datacollectedfromthedevicecouldbeusedtorecognizedifferentparticipantsbasedonhowtheytyped,withverylowerrorrates.Theresearcherssaythatthekeyboardshouldbeprettystraightforwardtocommercializeandismostlymadeofinexpensive,plastic-likeparts.Theteamhopestomakeittomarketinthenearfuture.28.Whydotheresearchersdevelopthesmartkeyboard?A.Toreducepressureonkeys.B.ToimproveaccuracyintypingC.Toreplacethepasswordsystem.D.Tocutthecostofe-spaceprotection.29.Whatmakestheinventionofthesmartkeyboardpossible？A.Computersaremucheasiertooperate.B.Fingerprintscanningtechniquesdevelopfast.C.Typingpatternsvaryfrompersontoperson.D.Datasecuritymeasuresareguaranteed.30.Whatdotheresearchersexpectofthesmartkeyboard？all1osoisgitieocooll.A.It'llbeenvironment-friendly.B.It'llreachconsumerssoon.C.It'llbemadeofplastics.D.It'llhelpspeeduptyping.,优点英语31.Whereisthistextmostlikelyfrom?A.Adiary.B.AguidebookC.Anovel.D.Amagazine.【语篇解读】这是一篇说明文。数据和身份盗窃变得越来越普遍，目前，向指纹扫描等这些技术仍然是昂贵的。本文介绍了一种新的科技——智能键盘，它能给e-space用户带来安全，而且这项技术也不贵。28.D【解析】细节理解题。根据第一段的Atpresent,thesetechnologiesarestillexpensive,though.和第二段的ResearchersfromGeorgiaTechsaythattheyhavecome
