將其視為加劇威脅，而非與棲息地破壞并列的三大主要威脅之一。8.C*解析思路：題干問氣候變化與生物多樣性喪失之間的關(guān)系。根據(jù)第二段第三句"Climatechangeexacerbatestheseissuesbyalteringhabitatsanddisruptingthetimingofecologicalevents,suchasfloweringandmigration"可知，氣候變化通過改變棲息地和大致擾亂生態(tài)事件的時間（如開花和遷徙），加劇了這些問題。選項C"Itintensifiesthenegativeeffectsofotherthreats"(它加劇了其他威脅的負(fù)面影響)最符合原文。9.B*解析思路：題干問"exacerbates"的意思。根據(jù)第二段第三句"Climatechangeexacerbatestheseissues..."以及前文提到的"Habitatdestruction...aretheprimarythreats"可知，氣候變化加劇了由棲息地破壞等問題引起的威脅。"Exacerbates"意為使（問題、情況等）更嚴(yán)重。選項B"Worsens"意為惡化，符合語境。10.D*解析思路：題干問生物多樣性喪失的潛在長期社會后果。根據(jù)第二段最后一句"Thelossofbiodiversitynotonlydiminishesthenaturalbeautyoftheplanetbutalsoposessignificantriskstohumansocieties,potentiallyleadingtothecollapseofecosystemservices"可知，生物多樣性的喪失不僅減少了地球的自然美景，而且對人類社會構(gòu)成重大風(fēng)險，可能導(dǎo)致生態(tài)系統(tǒng)服務(wù)的崩潰。選項D"Potentialcollapseofecosystemservices"(生態(tài)系統(tǒng)服務(wù)的潛在崩潰)符合原文。11.A*解析思路：題干問文章的主要主題。通讀全文可知，文章討論了人工智能（AI）的發(fā)展，其在醫(yī)療診斷方面的應(yīng)用（如分析圖像），其在個性化治療方面的應(yīng)用，以及相關(guān)的倫理和實(shí)踐問題（如數(shù)據(jù)隱私、算法偏見、對工作者的影響）。核心是人工智能在醫(yī)療領(lǐng)域的應(yīng)用及其相關(guān)挑戰(zhàn)。選項A"TheapplicationofAIinhealthcareanditsassociatedchallenges"(人工智能在醫(yī)療領(lǐng)域的應(yīng)用及其相關(guān)挑戰(zhàn))概括了主要內(nèi)容。12.A*解析思路：題干問人工智能在哪個具體醫(yī)學(xué)應(yīng)用方面顯示出特別的前景。根據(jù)第三段第二句"OneofthemostpromisingapplicationsofAIliesinmedicaldiagnostics.Furthermore,AIalgorithms,particularlythosebasedondeeplearning,havedemonstratedremarkableaccuracyinanalyzingmedicalimagessuchasX-rays,MRIs,andCTscans,potentiallyenablingearlierdetectionofdiseaseslikecancer"可知，AI在醫(yī)學(xué)診斷領(lǐng)域前景廣闊，特別是在分析X光、MRI和CT掃描等醫(yī)學(xué)圖像方面顯示出驚人的準(zhǔn)確性，可能實(shí)現(xiàn)癌癥等疾病的早期檢測。選項A"Medicaldiagnostics,particularlyimageanalysis"(醫(yī)學(xué)診斷，特別是圖像分析)符合原文。13.B*解析思路：題干問利用人工智能制定個性化治療方案的優(yōu)勢。根據(jù)第三段第三句"Byanalyzingvastamountsofpatientdata,includinggeneticinformation,AIcanhelpclinicianstailortherapiestoindividualpatients,optimizingtreatmenteffectivenessandminimizingsideeffects"可知，通過分析大量的患者數(shù)據(jù)（包括遺傳信息），人工智能可以幫助臨床醫(yī)生為個別患者量身定制療法，優(yōu)化治療效果并最大程度地減少副作用。選項B"Optimizingtreatmenteffectivenessandminimizingsideeffectsforindividualpatients"(優(yōu)化個體患者的治療效果并減少副作用)符合原文。14.C*解析思路：題干問"facilitating"的意思。根據(jù)第二段第二句"AIalgorithms,particularlythosebasedondeeplearning,havedemonstratedremarkableaccuracyinanalyzingmedicalimagessuchasX-rays,MRIs,andCTscans,*facilitating*earlierdetectionofdiseaseslikecancer"可知，AI算法在分析醫(yī)學(xué)圖像方面的準(zhǔn)確性有助于實(shí)現(xiàn)癌癥等疾病的早期檢測。"Facilitating"在這里意為促進(jìn)、使能夠。選項C"Enabling"意為使能夠，符合語境。15.D*解析思路：題干問人工智能在醫(yī)療保健中公平應(yīng)用的關(guān)鍵挑戰(zhàn)。根據(jù)第三段最后一句"Furthermore,ensuringthatAItechnologiesareaccessibleandequitable,particularlyinunderservedregions,remainsachallenge"可知，確保人工智能技術(shù)是可及的和公平的，特別是在服務(wù)不足的地區(qū)，仍然是一個挑戰(zhàn)。選項D"Ensuringaccessibilityandequity,especiallyinunderservedregions"(確?？杉靶院凸叫裕貏e是在服務(wù)不足的地區(qū))符合原文。16.(a)Therapiddevelopmentofartificialintelligencetechnologies*(b)Theflexibilityofferedbyremotework*(c)Concessiverelationship(or"Contrastrelationship")*解析思路：*(a)句子的主語是"Therapiddevelopmentofartificialintelligencetechnologies"（人工智能技術(shù)的快速發(fā)展）。*(b)"transformedvariousindustries"是一個過去分詞短語，在句中作結(jié)果狀語，修飾前面的"Therapiddevelopmentofartificialintelligencetechnologies"，說明其帶來的結(jié)果，即“改變了各個行業(yè)”。*(c)句子的結(jié)構(gòu)是"Therapiddevelopmentofartificialintelligencetechnologieshasnotonlytransformed...butalsopresented..."。"Notonly...butalso..."是一個表示遞進(jìn)或并列關(guān)系的連接詞組，但在這里更側(cè)重于引出與前面情況不同的另一面，帶有讓步或?qū)Ρ鹊囊馕?，可以理解為讓步關(guān)系或轉(zhuǎn)折關(guān)系。17.(a)Thecomplexandinterconnectednatureofecosystemsandtheirresponsestovariouspressures.*(b)Thattheyrelyoneachotherandfunctionasaunifiedsystem.*(c)Itfunctionsasanadverbialclauseofreason,explainingwhyunderstandinglong-termconsequencesisdifficult.*解析思路：*(a)句子的主語是"Duetotheintricatenetworkofinterdependentecosystemsthatareconstantlyevolvinginresponsetobothnaturalphenomenaandhuman-inducedpressures"（由于錯綜復(fù)雜的、相互依賴的生態(tài)系統(tǒng)網(wǎng)絡(luò)，這些生態(tài)系統(tǒng)在不斷應(yīng)對自然現(xiàn)象和人為壓力而演變）。這部分解釋了理解長期后果困難的原因。*(b)"interdependent"意為相互依賴的。根據(jù)句子"Duetotheintricatenetworkofinterdependentecosystems..."可知，這些生態(tài)系統(tǒng)是相互依賴、相互聯(lián)系的。選項意為“它們相互依賴，作為一個統(tǒng)一的系統(tǒng)運(yùn)作”。*(c)"Duetotheintricatenetworkofinterdependentecosystems..."是一個由"Dueto"引導(dǎo)的原因狀語從句，它解釋了主句"fullyunderstandingthelong-termconsequencesofanysingleenvironmentalinterventionremainsanexceptionallydemandingtaskforscientists"（全面理解任何單一環(huán)境干預(yù)的長期后果對科學(xué)家來說仍然是一項極其艱巨的任務(wù)）的原因。18.(a)Increasedflexibilityandpotentialreductionsincommutingtime.*(b)Difficultiesinmaintainingteamcohesion.*(c)"Drawbacks"referstothepotentialnegativeconsequencesmentioned.*解析思路：*(a)題干中的"Whilethebenefitsofremotework,suchasincreasedflexibilityandpotentialreductionsincommutingtime,areoftenhighlighted..."指出，遠(yuǎn)程工作的好處，例如靈活性增加和通勤時間可能減少，通常被強(qiáng)調(diào)。選項"Increasedflexibilityandpotentialreductionsincommutingtime"概括了原文提到的優(yōu)勢。*(b)題干中的"...thepotentialdrawbacks,includingdifficultiesinmaintainingteamcohesion..."指出，潛在的缺點(diǎn)包括維持團(tuán)隊凝聚力的困難。選項"Difficultiesinmaintainingteamcohesion"指的是原文提到的缺點(diǎn)之一。*(c)題干中的"Whataspectofremoteworkisidentifiedasapotentialnegativeconsequence?"指出，文章中確定的遠(yuǎn)程工作的潛在負(fù)面后果是什么。原文中"drawbacks"指的是前面列舉的"difficultiesinm
