B．Toimproveaccuracyintyping.C．Toreplacethepasswordsystem.D．Tocutthecostofespaceprotection.解析：推理判断题。根据第一段最后一句“Atpresent，thesetechnologiesarestillexpensive，though.”以及第二段第一句“ResearchersfromGeorgiaTechsaythattheyhaveeupwithalowcostdevicethatgetsaroundthisproblem:asmartkeyboard.”可推知，研究者研发这种智能键盘是为了降低网络安全保护技术的成本。注意题干、正确选项以及原文中一些词汇的多次呼应现象：develop与eupwith是同义词，expensive与lowcost是反义词，cutthecost与lowcost相呼应。答案：D29．Whatmakestheinventionofthesmartkeyboardpossible?A．putersaremucheasiertooperate.B．Fingerprintscanningtechniquesdevelopfast.C．Typingpatternsvaryfrompersontoperson.D．Datasecuritymeasuresareguaranteed.解析：推理判断题。题干问的是“是什么让智能键盘的发明成为可能”，也就是问这一发明的核心依据是什么。根据第二段中的“Thesepatternsareuniquetoeachperson.Thus，thekeyboardcandeterminepeople'sidentities...”可知，正是因为每个人的打字模式不同，这种智能键盘就可以通过分析用户的打字力度及节奏等来判断该用户是不是安全访客，故C项符合题意。-18-/18
优选答案：C30．Whatdotheresearchersexpectofthesmartkeyboard?A．It'llbeenvironmentfriendly.B．It'llreachconsumerssoon.C．It'llbemadeofplastics.D．It'llhelpspeeduptyping.解析：细节理解题。根据题干“研究者对于智能键盘有什么期望”可直接定位到最后一段的最后一句话“Theteamhopestomakeittomarketinthenearfuture.(该团队希望在不久的将来将智能键盘推向市场)”，故选B项。注意：题干中的expect与原文中的hope呼应，答案选项中的consumers与原文中的market呼应。答案：B31．Whereisthistextmostlikelyfrom?A．Adiary.B．Aguidebook.C．Anovel.D．Amagazine.解析：文章出处题。根据本文的话题“智能键盘”以及第二段中的“ResearchersfromGeorgiaTechsaythattheyhaveeupwithalowcostdevice...”，尤其是其中的关键词researchers，lowcostdevice等来推断，这篇文章是一篇科研报道，最有可能出现在杂志上。答案：D一、语言能力熟词生义/词类活用1．getaround克服，解决2．applyto施加3．accessn．权利4．makeitto赶上，成功到达二、思维品质1．阅读技巧——文章出处题-18-/18
