确。5.【答案】B【解析】事实细节题。Passage3中指出“Duringtheslow-wavesleepphase,thehippocampusreplaystheday'sexperiences,transferringthemtotheneocortexforpermanentstorage.”。选项B“海马体将日常经历转移到新皮层进行永久存储”是对此句的准确同义替换。6.【答案】C【解析】推理判断题。文章提及大脑在深度睡眠期间清理如amyloid-beta（淀粉样蛋白β）等代谢废物，而这些多肽的积累与阿尔茨海默症的发病密切相关。因此，长期睡眠剥夺会阻碍这一清理过程，增加阿尔茨海默症的风险。C项正确反映了这一逻辑关系。UseofEnglish7.【答案】B【解析】词义逻辑题。传统计算机分解大质数需要指数级的时间，这使得暴力破解实际上是“不可行的”。选项Bunfeasible符合逻辑。feasible意为“可行的”，advantageous意为“有利的”，detrimental意为“有害的”，均不符合语境。8.【答案】B【解析】细节推断题。文章提到“reducesthetimecomplexitytopolynomialtime,specificallyO(n3)”。在数学与计算机科学中，O(9.【答案】B【解析】语境连贯题。前文提到量子计算机能以多项式时间破解需要指数级时间的问题，这意味着足够强大的量子计算机能“毫不费力地”解密当前安全的数据。effortlessly符合语境。theoretically虽常用于量子计算语境，但结合Shor算法已将复杂度从指数级降为多项式级，其实际破解能力是显著增强的，此处强调其能力之强，B项更贴合语境。10.【答案】A【解析】名词辨析题。句子主语是Lattice-basedcryptography（基于格的密码学），它在后量子密码学领域是一个领先的“候选者/方案”。candidate最符合语境。11.【答案】A【解析】句意理解题。前文提到最短向量问题（SVP），此处解释其数学表述，即“在数学上被表述/形式化为求解方程L·→x=→b”。formulated意为“表述、系统阐述”，符合学术语境。12.【答案】B【解析】动词搭配题。过渡阶段“呈现/带来”了众多实施挑战。presents在此意为“呈现、带来”，常与challenges,problems搭配。complicates（使复杂化）、eliminates（消除）、avoids（避免）均不符合句意。13.【答案】C【解析】名词辨析题。在全球网络范围内标准化新算法是一项复杂的后勤“尝试/任务”。endeavor意为“尝试、努力、事业”，在此指代一项艰巨的任务。asset（资产）、paradigm（范式）、liability（负债、责任）不符合语境。14.【答案】B【解析】动词逻辑题。采用密码敏捷性的目的是为了“减轻”潜在漏洞。mitigate意为“减轻、缓解”，最符合上下文逻辑。exploit（利用）、intensify（加剧）、identify（识别）均与目的相悖。ReadingComprehensionSubsectionA15.【答案】B【解析】推理判断题。文章首句指出“theprevailingscientificconsensusheldthattheadulthumanbrainwasimmutable,incapableofgeneratingnewneuronsaftermaturation.”。immutable意为“不可改变的”，与B项中的unchangeable同义替换，且incapableofgeneratingnewneurons对应couldnotproducenewneurons。16.【答案】B【解析】事实细节题。第二段提到“thecontinuousintegrationofnewneuronsisbelievedtofacilitatepatternseparation—theabilitytodistinguishbetweenhighlysimilarbutdistinctexperiences.”。B选项直接对应这一描述，即促进模式分离，区分相似经历。17.【答案】D【解析】推理判断题。第二段末尾指出“interventionsthatenhanceneurogenesis,suchasaerobicexerciseandenrichedenvironments,havebeenshowntoimprovecognitiveflexibility...”。有氧运动属于身体刺激，丰富的环境属于环境刺激，D项总结正确。A项错误，因为研究尚未成为主要临床疗法；B项与原文相反；C项无直接依据。18.【答案】B【解析】事实细节题。第三段提到“Whilemagneticresonanceimaging(MRI)canmapbrainstructure,itlacksthecellularresolutionrequiredtovisualizeindividualneurons.”。B项“由于细胞分辨率不足而无法可视化单个神经元”是对该句的准确复述。19.【答案】B【解析】目的推断题。文章最后一句提到“Ifsuccessful,suchneuroimagingtechniqueswouldnotonlyvalidatefindingsfromanimalmodelsbutalsoprovidecrucialbiomarkersforevaluatingtheefficacyofnovelantidepressantsandcognitiveenhancerstargetingneurogenicpathways.”。B项“为评估影响神经发生的药物疗效提供生物标志物”正是开发新型放射配体的最终目的。20.【答案】B【解析】事实细节题。文章第一段提到Haber-Bosch过程“allowedfortheindustrialfixationofatmosphericnitrogenintoammonia,revolutionizingagriculturalfertilizerproductionandconsequentlyenablingamassiveglobalpopulationboom.”。B选项“允许工业固氮，支持了大规模的人口增长”完全契合原文。21.【答案】C【解析】事实细节题。第一段指出未吸收的肥料“islosttotheenvironment,causingwidespreadeutrophicationinaquaticecosystems,theemissionofnitrousoxide—apotentgreenhousegas—andtheacidificationofsoils.”。C选项“导致富营养化、温室气体排放和土壤酸化”全面涵盖了这些影响。22.【答案】C【解析】事实细节题。第二段提到“PrecisionagricultureutilizesremotesensingandGPSmappingtooptimizefertilizerapplication,ensuringthatnitrogenisappliedonlywhereandwhenneeded,therebyminimizingrunoff.”。C选项“利用先进地图优化肥料施用以最小化径流”准确描述了精准农业的作用机制。23.【答案】B【解析】推理判断题。文章最后一句提到“Theenvironmentalcostsofnitrogenpollutionarerarelyinternalizedbyagriculturalproducers,creatingamarketfailurewheresyntheticfertilizersremainartificiallycheap.”。由于生产者没有内部化环境成本（即没有承担污染的代价），导致市场失灵，B项正确。24.【答案】A【解析】推理判断题。文章指出向可持续氮管理过渡受到“economicbarriersandalackofstringentpolicyframeworks”的阻碍，且市场失灵导致化肥价格人为偏低。可以推断，为了实现可持续管理，必须克服经济障碍并建立更严格的政策框架。A项符合逻辑推断。SubsectionB25.【答案】B,D,E【解析】多项选择题。文章提到“thenuancedecologicalknowledgeembeddedwithinthemisoftenlostforever”，这支持了B项“土著语言的丧失直接导致细微生态知识的丧失”。文章提到“spiritualbeliefsthatactivelypromotebiodiversityconservation”，这支持了D项“土著精神信仰在促进生物多样性保护中发挥功能作用”。文章提到“erosionofTEKduetoglobalization,
