B．Toimproveaccuracyintyping.C．Toreplacethepasswordsystem. D．Tocutthecostofe-spaceprotection.解析：推理判斷題。根據(jù)第一段最后一句“Atpresent，thesetechnologiesarestillexpensive，though.”以及第二段第一句“ResearchersfromGeorgiaTechsaythattheyhavecomeupwithalow-costdevicethatgetsaroundthisproblem:asmartkeyboard.”可推知，研究者研發(fā)這種智能鍵盤是為了降低網(wǎng)絡(luò)安全保護(hù)技術(shù)的成本。注意題干、正確選項(xiàng)以及原文中一些詞匯的多次呼應(yīng)現(xiàn)象：develop與comeupwith是同義詞，expensive與low-cost是反義詞，cutthecost與low-cost相呼應(yīng)。答案：D29．Whatmakestheinventionofthesmartkeyboardpossible?A．Computersaremucheasiertooperate.B．Fingerprintscanningtechniquesdevelopfast.C．Typingpatternsvaryfrompersontoperson.D．Datasecuritymeasuresareguaranteed.解析：推理判斷題。題干問的是“是什么讓智能鍵盤的發(fā)明成為可能”，也就是問這一發(fā)明的核心依據(jù)是什么。根據(jù)第二段中的“Thesepatternsareuniquetoeachperson.Thus，thekeyboardcandeterminepeople'sidentities...”可知，正是因?yàn)槊總€(gè)人的打字模式不同，這種智能鍵盤就可以通過分析用戶的打字力度及節(jié)奏等來判斷該用戶是不是安全訪客，故C項(xiàng)符合題意。答案：C30．Whatdotheresearchersexpectofthesmartkeyboard?A．It'llbeenvironment-friendly. B．It'llreachconsumerssoon.C．It'llbemadeofplastics. D．It'llhelpspeeduptyping.解析：細(xì)節(jié)理解題。根據(jù)題干“研究者對(duì)于智能鍵盤有什么期望”可直接定位到最后一段的最后一句話“Theteamhopestomakeittomarketinthenearfuture.(該團(tuán)隊(duì)希望在不久的將來將智能鍵盤推向市場)”，故選B項(xiàng)。注意：題干中的expect與原文中的hope呼應(yīng)，答案選項(xiàng)中的consumers與原文中的market呼應(yīng)。答案：B31．Whereisthistextmostlikelyfrom?A．Adiary. B．Aguidebook.C．Anovel. D．Amagazine.解析：文章出處題。根據(jù)本文的話題“智能鍵盤”以及第二段中的“ResearchersfromGeorgiaTechsaythattheyhavecomeupwithalow-costdevice...”，尤其是其中的關(guān)鍵詞researchers，low-costdevice等來推斷，這篇文章是一篇科研報(bào)道，最有可能出現(xiàn)在雜志上。答案：D一、語言能力熟詞生義/詞類活用1．getaround_______________2．a(chǎn)pplyto_________3．a(chǎn)ccessn．_________4．makeitto___________________克服，解決施加權(quán)利趕上，成功到達(dá)二、思維品質(zhì)1．閱讀技巧——文章出處題此類試題考查對(duì)文章體裁以及文章的出處進(jìn)行合理判斷的能力。如第31題。常見設(shè)問方式：(1)Thispassagecanbeclassifiedas____________________.(2)Thetextismostprobablya____________________.(3)Wheredoesthetextprobablycomefrom?(4)Wherecanyoufindthispassage?常見文章出處：①newspaper(報(bào)紙)
