s,suchasX-raysandMRIs,withspeedsandsometimeslevelsofdetailsurpassinghumancapabilities.”这表明AI系统当前被用于分析医学影像，如X光和核磁共振图像。3.B*解析思路：根据上下文，“transformativeforce”指的是AI对众多领域产生的根本性、革命性的影响。选项B（根本性的）与这个意思最接近。选项A（创造性的）和选项C（破坏性的）不够全面或准确。选项D（暂时的）与文章基调不符。4.C*解析思路：文章第二段提到AI“servesasapowerfultooltoassistthem,flagginganomaliesthatmightbemissedandprovidingsecondopinions.”并且明确指出“doesnotreplaceskilledradiologistsbutratherservesasapowerfultooltoassistthem”。选项C（提高诊断的准确性和效率）概括了AI作为辅助工具的主要潜在好处，超越了仅仅提供协助或第二意见。5.D*解析思路：文章最后一段明确列出了AI在医疗保健领域的挑战，包括“dataprivacy,algorithmicbias,andtheneedforrobustregulatoryframeworkstoensureethicaldeploymentandpatientsafety.”选项D（数据隐私、算法偏见以及需要强有力的监管框架）包含了这些核心挑战。选项A（提高效率）是AI的潜在益处。选项B（增强诊断能力）是AI的应用。选项C（环境问题）未在文章中提及。6.B*解析思路：文章最后一段提到“thefuturelikelyholdsevenmoreintegratedAIsolutions,promisingfurtherimprovementsinpatientcareandoperationalefficiencywithinhealthcaresettings.”这表明文章暗示未来AI将在医疗保健中实现更深度的整合，并带来进一步的改进。第二部分7.A*解析思路：文章首段明确指出“Sustainableurbandevelopmenthasbecomeacriticalfocus...”，并接着阐述了其重要性及内容。选项A（论述可持续城市发展的必要性和关键要素）最能概括文章的主要目的。8.C*解析思路：文章第一段描述了传统城市增长模式的特征，提到“sprawlingsuburbs,extensivecardependency,andsignificantenvironmentaldegradation.”选项C（蔓延的郊区、广泛的汽车依赖以及严重的环境退化）概括了这些特点。9.B*解析思路：第一段介绍了可持续城市发展的背景和重要性，第二段接着提到“Keycomponentsofthissustainableapproachinclude...”。“consequently”在这里表示因果关系，即由于前述背景和重要性，所以出现了后述的可持续发展的关键组成部分。10.A*解析思路：文章第二段提到，“Theseelements[compactlanduse,publictransport,greenspaces]notonlyreducecarbonemissionsandmitigatetheurbanheatislandeffectbutalsoenhancethequalityoflife...improveairquality.”选项A（减少碳排放）是直接与绿色空间发展相关的积极环境结果。11.D*解析思路：文章第二段提到可持续城市的目标之一是“aimingtocreatevibrant,inclusivecommunities.”并且提到“prioritizeaffordablehousingandaccesstoessentialservicesforallinhabitants”。选项D（为所有居民提供可负担住房和经济适用房以及基本服务的平等机会）体现了这一社会目标。12.E*解析思路：文章最后一段指出，“Achievingsustainableurbandevelopmentrequirescollaborationamonggovernments,businesses,andresidents,aswellaslong-termplanningandinvestmentininnovativeinfrastructureandtechnologies.”这表明成功需要政府、企业和居民的合作以及长期的规划、投资和创新基础设施。第三部分13.C*解析思路：文章主要讨论了数字革命如何改变媒体领域，以及传统媒体面临的挑战和新媒体的特点。选项C（数字革命对媒体领域的影响）最能概括文章的中心思想。选项A（社交媒体的兴起）和选项B（传统媒体的衰落）只是文章讨论的方面。选项D（算法在信息传播中的作用）也是重要内容，但不是最全面的概括。14.B*解析思路：文章第一段明确提到，“Thisshifthasledtosignificantchangesinconsumerbehavior,withaudiencesincreasinglyexpectingimmediateaccesstonews,personalizedcontentfeeds,anddiverseperspectivesoftencuratedbyalgorithmsratherthanhumaneditors.”这表明数
