子是为了证明AI可以替代认知任务，但不能替代人际互动的角色。故选C。25.【答案】A【解析】细节理解题。根据最后一段"Workerswillneedtotransitionfromrepetitive,rule-basedtaskstorolesthatemphasizecreativity,criticalthinking,andinterpersonalcommunication."（工人将需要从重复性、基于规则的任务转向强调创造力、批判性思维和人际沟通的角色）。可知未来的劳动力市场需要工人发展创造力和沟通技能。故选A。Text226.【答案】B【解析】细节理解题。根据第一段"TheTibetanPlateau,oftenreferredtoasthe'ThirdPole'duetoitsvasticereserves..."（青藏高原，由于其巨大的冰储量，通常被称为“第三极”）。可知它被称为第三极是因为它拥有巨大的冰储量。故选B。27.【答案】B【解析】细节理解题。根据第二段"Thethawingofpermafrosthasprofoundecologicalconsequences.Itnotonlyreleasestrappedgreenhousegases...butitalsoaltersthestabilityofthegrasslands."（永久冻土的融化产生了深远的生态后果。它不仅释放了被困的温室气体……而且改变了草原的稳定性）。A项增加牲畜数量、C项扩大湿地、D项降低全球气温均与原文相悖。故选B。28.【答案】B【解析】细节理解题。根据第二段"Thereductioningrazinglandhasforcedmanyherderstoreducetheirlivestockorabandontheirtraditionalwayoflifeentirely..."（放牧地的减少迫使许多牧民减少牲畜或完全放弃他们的传统生活方式……）。故选B。29.【答案】B【解析】推理判断题。文章给出的公式为B(t)=(1−)。这是一个典型的负指数增长模型。当时间t显著增加时，趋近于0，因此130.【答案】C【解析】细节理解题。根据最后一段"Furthermore,balancingecologicalpreservationwiththeeconomicneedsofthelocalpopulationremainsadelicatetask."（此外，平衡生态保护与当地人口的经济需求仍然是一项微妙的任务）。故选C。Text331.【答案】B【解析】细节理解题。根据第一段"The'SmartCity2.0'modelemphasizeshuman-centricdesign,wheretechnologyisnottheendgoalbutatooltoenhancethequalityoflifeforitsresidents."（“智慧城市2.0”模式强调以人为本的设计，其中技术不是最终目标，而是提高居民生活质量的工具）。而最初的模型是"heavilyfocusedontechnologicalinfrastructure"（严重侧重于技术基础设施）。故选B。32.【答案】C【解析】细节理解题。根据第二段"whileasophisticatedsurveillancesystemmightreducecrimeratesstatistically,itoftenalienatesmarginalizedcommunitiesandraisessignificantprivacyconcerns."（虽然复杂的监控系统可能在统计上降低了犯罪率，但它往往疏远了边缘化社区，并引发了重大的隐私问题）。故选C。33.【答案】C【解析】细节理解题。根据第三段"Tocounterthis,modernurbanplannersarefocusingonaccessibletechnologies."（为了应对这一点，现代城市规划者正在关注无障碍技术），并提到了在低收入社区提供免费Wi-Fi等包容性措施。故选C。34.【答案】B【解析】词义猜测题。短语"anequalizerratherthanadivider"字面意思是“是平等化工具而不是分裂者”。结合前文提到的解决数字鸿沟、关注包容性和无障碍技术，可以推断出作者认为技术应该为所有公民提供平等的机会和访问权。故选B。35.【答案】C【解析】观点态度题。文章详细阐述了SmartCity2.0模式的优势和改进之处，如以人为本、关注包容性等，最后一句提到"Theultimategoalistocreateanurbanenvironmentwheretechnologyservesasanequalizer..."（最终目标是创造一个技术作为平等化工具的城市环境）。可见作者对这一模式持支持态度。故选C。PartB36.【答案】B【解析】段落主题句为"ThehistoryofteaisdeeplyintertwinedwithChineseculture,datingbacktoancienttimes.Accordingtopopularlegend..."，随后讲述了神农发现茶的故事。核心在于茶的神话起源。B项Themythologicaloriginsoftea（茶的神话起源）最贴切。37.【答案】F【解析】段落主题句为"Initially,teawasnotconsumedasadailybeveragebutwasprimarilyusedforitsmedicinalproperties."，随后详细列举了古代医学文献对茶药用价值的记载。F项TheearlymedicinaluseofteainChina（茶在古代中国的药用）最贴切。38.【答案】D【解析】段落讲述了唐代茶从药用转为日常饮品，陆羽《茶经》的诞生，以及茶成为社会文化生活的核心，发展出复杂的茶道。D项TheculturalsignificanceofteainTangDynasty（茶在唐代的文化意义）最贴切。39.【答案】A【解析】段落主题句为"TheintroductionofteatotheWestcanbeattributedtoDutchandPortuguesetraders..."，讲述了茶如何传入西方并影响全球贸易。A项ThespreadofteatotheWesternworld（茶向西方世界的传播）最贴切。40.【答案】C【解析】段落讲述了现代科学对茶健康益处的验证，如富含抗氧化剂、降低心血管疾病风险等。C项Theroleofteainmodernmedicine（茶在现代医学中的作用）最贴切。SectionIVWritingPartADearMr.Smith,Iamwritingtoreportonthehighlysuccessfulanimaladoptioneve
