主旨。選項(xiàng)B（AI輔助診斷）和選項(xiàng)C（AI在醫(yī)療影像中的應(yīng)用）只是文章討論的具體方面，而非整體主旨。2.A*解析思路：文章第二段明確提到，“AIsystemscannowanalyzemedicalimages,suchasX-raysandMRIs,withspeedsandsometimeslevelsofdetailsurpassinghumancapabilities.”這表明AI系統(tǒng)當(dāng)前被用于分析醫(yī)學(xué)影像，如X光和核磁共振圖像。3.B*解析思路：根據(jù)上下文，“transformativeforce”指的是AI對(duì)眾多領(lǐng)域產(chǎn)生的根本性、革命性的影響。選項(xiàng)B（根本性的）與這個(gè)意思最接近。選項(xiàng)A（創(chuàng)造性的）和選項(xiàng)C（破壞性的）不夠全面或準(zhǔn)確。選項(xiàng)D（暫時(shí)的）與文章基調(diào)不符。4.C*解析思路：文章第二段提到AI“servesasapowerfultooltoassistthem,flagginganomaliesthatmightbemissedandprovidingsecondopinions.”并且明確指出“doesnotreplaceskilledradiologistsbutratherservesasapowerfultooltoassistthem”。選項(xiàng)C（提高診斷的準(zhǔn)確性和效率）概括了AI作為輔助工具的主要潛在好處，超越了僅僅提供協(xié)助或第二意見。5.D*解析思路：文章最后一段明確列出了AI在醫(yī)療保健領(lǐng)域的挑戰(zhàn)，包括“dataprivacy,algorithmicbias,andtheneedforrobustregulatoryframeworkstoensureethicaldeploymentandpatientsafety.”選項(xiàng)D（數(shù)據(jù)隱私、算法偏見以及需要強(qiáng)有力的監(jiān)管框架）包含了這些核心挑戰(zhàn)。選項(xiàng)A（提高效率）是AI的潛在益處。選項(xiàng)B（增強(qiáng)診斷能力）是AI的應(yīng)用。選項(xiàng)C（環(huán)境問題）未在文章中提及。6.B*解析思路：文章最后一段提到“thefuturelikelyholdsevenmoreintegratedAIsolutions,promisingfurtherimprovementsinpatientcareandoperationalefficiencywithinhealthcaresettings.”這表明文章暗示未來(lái)AI將在醫(yī)療保健中實(shí)現(xiàn)更深度的整合，并帶來(lái)進(jìn)一步的改進(jìn)。第二部分7.A*解析思路：文章首段明確指出“Sustainableurbandevelopmenthasbecomeacriticalfocus...”，并接著闡述了其重要性及內(nèi)容。選項(xiàng)A（論述可持續(xù)城市發(fā)展的必要性和關(guān)鍵要素）最能概括文章的主要目的。8.C*解析思路：文章第一段描述了傳統(tǒng)城市增長(zhǎng)模式的特征，提到“sprawlingsuburbs,extensivecardependency,andsignificantenvironmentaldegradation.”選項(xiàng)C（蔓延的郊區(qū)、廣泛的汽車依賴以及嚴(yán)重的環(huán)境退化）概括了這些特點(diǎn)。9.B*解析思路：第一段介紹了可持續(xù)城市發(fā)展的背景和重要性，第二段接著提到“Keycomponentsofthissustainableapproachinclude...”?！癱onsequently”在這里表示因果關(guān)系，即由于前述背景和重要性，所以出現(xiàn)了后述的可持續(xù)發(fā)展的關(guān)鍵組成部分。10.A*解析思路：文章第二段提到，“Theseelements[compactlanduse,publictransport,greenspaces]notonlyreducecarbonemissionsandmitigatetheurbanheatislandeffectbutalsoenhancethequalityoflife...improveairquality.”選項(xiàng)A（減少碳排放）是直接與綠色空間發(fā)展相關(guān)的積極環(huán)境結(jié)果。11.D*解析思路：文章第二段提到可持續(xù)城市的目標(biāo)之一是“aimingtocreatevibrant,inclusivecommunities.”并且提到“prioritizeaffordablehousingandaccesstoessentialservicesforallinhabitants”。選項(xiàng)D（為所有居民提供可負(fù)擔(dān)住房和經(jīng)濟(jì)適用房以及基本服務(wù)的平等機(jī)會(huì)）體現(xiàn)了這一社會(huì)目標(biāo)。12.E*解析思路：文章最后一段指出，“Achievingsustainableurbandevelopmentrequirescollaborationamonggovernments,businesses,andresidents,aswellaslong-termplanningandinvestmentininnovativeinfrastructureandtechnologies.”這表明成功需要政府、企業(yè)和居民的合作以及長(zhǎng)期的規(guī)劃、投資和創(chuàng)新基礎(chǔ)設(shè)施。第三部分13.C*解析思路：文章主要討論了數(shù)字革命如何改變媒體領(lǐng)域，以及傳統(tǒng)媒體面臨的挑戰(zhàn)和新媒體的特點(diǎn)。選項(xiàng)C（數(shù)字革命對(duì)媒體領(lǐng)域的影響）最能概括文章的中心思想。選項(xiàng)A（社交媒體的興起）和選項(xiàng)B（傳統(tǒng)媒體的衰落）只是文章討論的方面。選項(xiàng)D（算法在信息傳播中的作用）也是重要內(nèi)容，但不是最全面的概括。14.B*解析思路：文章第一段明確提到，“Thisshifthasledtosignificantchangesinconsumerbehavior,withaudiencesincreasinglyexpectingimmediateaccesstonews,personalizedcontentfeeds,anddiverseperspectivesoftencuratedbyalgorithmsratherthanhumaneditors.”這表明數(shù)
