roundtunnels...snowmelt”。29.B【解析】作者在描述坎儿井系统干涸时使用了“drasticallyloweredthewatertable”,“driedup”,“lossofbothculturalheritageandagriculturalproductivity”，字里行间透出对这一遗产退化和流失的深切担忧。【高分策略】态度题。需抓取作者使用的形容词和副词的情感色彩，如“marvel”,“testamenttohumanadaptability”对比“driedup”,“loss”，可判断态度为“deeplyconcerned”。30.B【解析】文章指出柴油抽水井的大量使用导致地下水位“drasticallylowered”，即加剧了地下水资源的枯竭。【高分策略】推断题。通过“proliferationofdiesel-poweredtubewells...drasticallyloweredthewatertable”可直接推断B项正确。31.B【解析】文章核心论点是：算法并非中立，它们基于历史数据进行训练，而历史数据本身带有偏见，因此算法会延续并放大社会偏见。【高分策略】主旨题。需概括全文大意。第一句引出话题，第二句提出错误观点，第三句“However”转折后引出核心论点，后续展开论证。32.B【解析】“self-fulfillingprophecyofbias”（偏见的自我实现预言）指的是预测算法认为某地区犯罪率高，导致警察过度巡逻，进而逮捕更多少数族裔，这反过来又“验证”了算法的预测，形成恶性循环。【高分策略】语义推断题。需结合上下文的具体例子（predictivepolicing）理解。选项B准确描述了这一反馈循环机制。33.A,C,E【解析】A对应“instantlyinfluences...regardlessofdistance”。C对应“physicistshaverecentlyentangledmacroscopicobjects”。E对应“challengestheboundarybetweenthequantumandclassicalworlds”。B错在Einstein称其为“spookyaction”，表示反对。D错在decoherence会破坏量子态，而非维持。【高分策略】多选题在PETS-5中极易失分。必须逐个选项与原文严格比对，切忌主观臆断。通常干扰项会将原文中的否定改为肯定，或偷换概念。34.A,B【解析】A对应“extremeisolationfromtheoutsideenvironment”。B对应“decoherence...destroysthequantumstate”。C是理论层面的异议，非实际挑战。D在文中未提及，文中说的是potentiallyrevolutionizingcryptography。【高分策略】同上，精准定位。区分“理论争议”与“实际工程挑战”。35.Becauseinformationisabundantinthedigitalage,makinghumanattentionthelimitingandscarceresource.【解析】原文第一段提到“informationisabundant,buthumanattentionisscarce.”【高分策略】简答题需精简。直接回答核心原因：信息过剩导致注意力相对稀缺。36.Theerosionofdeepcognitiveprocessing,thepolarizationofpublicdiscourse,andthedegradationofpsychologicalwell-being.【解析】原文列举了三个负面外部性：深度认知处理的削弱、公共话语的两极化、心理健康的退化。【高分策略】需准确抓取并列的名词短语。可适当进行同义替换，但核心词汇不可遗漏。37.Annualwatersavingsincubicmeters=2,500,000Monetaryvalueofsavedwater=2,500,000*1.2=3,000,000RMBAnnualmaintenancecost=500,000RMBAnnualnetfinancialbenefit(PMT)=3,000,000-500,000=2,500,000RMB.【解析】计算逻辑：水节约量乘以水价得出节约金额，减去维护成本即为纯年收益。【高分策略】计算题要求逻辑严密，步骤清晰。务必写出公式和代入过程，即使最终结果计算有微小误差，步骤分依然可得。38.Initialcost=8,000,000RMBPVofannuityofnetbenefits=2,500,000*[(1-(1+0.05)^{-10})/0.05](1.05)^{-10}≈0.6139PVofannuity=2,500,000*[(1-0.6139)/0.05]=2,500,000*[0.3861/0.05]=2,500,000*7.7217≈19,304,250RMBNPV=PVofinflows-InitialOutlay=19,304,250-8,000,000=11,304,250RMB.【解析】使用年金现值公式计算10年期净收益的折现现值，减去期初投资得到净现值。【高分策略】熟练运用LaTeX格式书写公式（如考试为机考）。掌握复利现值系数的近似计算，约为0.6139。NPV的实质是未来现金流现值减去初始投资。39.First,therehabilitatedKarezsystemrepresentsavitalculturalandhistoricalheritage,preservingthetraditionalengineeringknowledgeandidentityofthelocalUyghurcommunities.Second,itoperatesentirelyongravityandnaturalflow,resultinginazero-carbonfootprint,whichalignswithstringentsustainabilityandcarbon-neutralgoals,unliketheelectricpumpsrequiredforProjectA.【解析】非财务优势需从文化历史价值和环保（零碳排放）角度切入。【高分策略】分析题不仅看数字，还要具备跨学科思维。结合文章中提到的坎儿井的历史文化属性和自然重力引水的环保属性进行作答。40.Recommendation:WhiletherelocationtoTurpanpresentscompellingfinancialincentives,notablythesignificantlylowerlaborcostshighlightedbytheCFO,afull-scaleprimarydatacenterrelocationisstrategicallyrisky.TheCTO'sconcernsregardingextremesummerheatandsandstormsaretechnicallyvalid;serverfailureratesspikeexponentiallyinsuchharsh,abrasiveenvironments,andtherequiredrobustcoolingsystemswouldseverelyoffsetthewintercoolingsavingschampionedbytheCEO.Furthermore,theHRdirector'swarningiscritical:thelossofspecializedITtalentwouldparalyzeoperationsandincurmassiveretrainingexpenses.Therefore,aviablecompromiseistoestablishaTier-2"failover"orstoragedatacenterinTurpan,ratherthanmovingtheprimaryoperationalhub.Thissetupcapitalizesonthecheaprealestateandlaborforroutinemaintenanceanddataarchiving,whilekeepingtheprimary,highlysensitiveoperationalserversinShanghaiwheretalentdensityandenvironmentalstabilityareoptimal.TofurthermitigatetheCTO'sconcerns,specializedhermeticallysealedcontainerswithindependentcoolingsystemsmustbedeployedintheTurpanfacilitytoprotectagainstsandstormingress.【解析】本题考查综合分析和商务写作能力。必须涵盖所有高管的观点（CEO的冬季冷却、CTO的高温和沙尘、CFO的低人力成本、HR的人才流失），并提出折中方案。
