ressure.”），表明他主要谈论的是完成这个有挑战性的项目。A（他的工作日常）未提及。B（他对团队的建议）是项目完成后的反思，非主要内容。D（他如何平衡工作和生活）未深入讨论。2.A*解析思路：Mark提到项目最困难的部分是“tryingtointegratethefeedbackfromthreedifferentdepartmentssimultaneously.Communicationwasabitchaoticattimes”。明确指出困难在于来自三个不同部门的反馈整合以及沟通混乱。B（时间压力）是普遍存在的，但不是他特别强调的最难点。C（工作量）是原因之一，但核心在于整合反馈带来的沟通问题。D（技术难度）未提及。3.B*解析思路：Mark评价说“Theteamactuallydidagreatjobcollaboratingunderpressure”。直接使用了“greatjob”和“collaboratingunderpressure”来描述团队的表现，语气是积极的肯定。4.D*解析思路：Mark在反思后建议“Maybeimplementashareddigitalplatform?Andmaybesetmorerealisticdeadlinesnexttime.”。明确提出了两点建议：一是实施一个共享的数字平台（改进沟通），二是设定更现实的时间截止日期。A（雇佣更多员工）未提及。B（增加营销投入）针对的是NorthAmericanmarket的增长，非通用建议。C（进行市场调研）是项目前的工作，非改进协作流程的建议。5.C*解析思路：对话发生在Mark（可能是一位同事或下属）和Sarah（被称为Sarah）之间，讨论的是Mark的“newproject”以及需要John准备的“presentationfortheboardmeeting”。这种工作相关的交流，且涉及项目成果汇报和团队协作，最可能的身份关系是同事或上下级关系。A（师生关系）不符合讨论内容和称呼。B（医患关系）与对话主题不符。D（亲威关系）在工作场景中可能性较低。6.D*解析思路：对话开头John询问Sarah是否完成了季度销售报告以准备董事会会议演示，Sarah回答“almostdone”并提到正在分析国际数据。John接着问“Didyounoticeanysignificanttrendsthisquarter?”，Sarah也回答了有关北美和欧洲市场的趋势问题。最后John说“I'llincorporateyourinsightsintothepresentation.”，明确指出他们正在为同一个演示文稿工作。因此，主要目的是讨论即将进行的演示文稿的内容。7.A*解析思路：Sarah明确提到“ourNorthAmericansalesincreasedquitesubstantially”，指出北美销售额有显著增长。对话中没有提及其他市场增长幅度更大。8.B*解析思路：Sarah提到“ourEuropeanmarketsawaslightdecline”，明确指出欧洲市场出现了轻微下滑。9.A*解析思路：Sarah建议“continueinvestingintheNorthAmericanmarketandperhapsexpandthecampaigntootherregions”，直接建议继续加大对北美市场的投入，并将营销活动扩展到其他地区。10.A*解析思路：John是“HiSarah”，Sarah是“HiJohn”，他们是直接互相称呼名字进行交流。John的工作是“needthemtopreparethepresentation”，Sarah的工作是“reviewingthequarterlysalesreports”。这种在工作环境中互相称呼名字、共同处理工作任务的对话，最可能的关系是同事。B（师生）不符。C（医患）不符。D（上下级）虽然可能，但仅凭对话内容无法完全确定，同事关系可能性更大。第二部分篇章理解11.A*解析思路：文章首句“Therapidadvancementofartificialintelligence(AI)hasbeenatransformativeforceacrossnumerousindustries,andhealthcareisnoexception.”点明了文章的核心主题——人工智能在医疗保健领域的快速发展及其影响。B（AI在药物研发中的应用）是文章讨论的一个方面。C（医疗数据隐私问题）是讨论的一个挑战。D（AI助手的作用）也是讨论的一个方面。但A选项最全面、最准确地概括了全文主旨。12.C*解析思路：文章第二段提到“Algorithmstrainedonvastdatasetscannowassistradiologistsindetectinganomaliessuchastumorsorfractureswithremarkableprecision,oftenfasterthanhumaneyesalone.Thiscapabilitynotonlyenhancesdiagnosticaccuracybutalsoreducestheburdenonhealthcareprofessionals.”，明确指出AI在医学影像分析方面的能力之一是“enhancesdiagnosticaccuracy”（提高诊断精度）。13.B*解析思路：文章第三段提到“AIisalsostreamliningpatientinteractionsthroughtoolslikevirtualhe
