間找到平衡。）這與B選項(xiàng)（我們需要培養(yǎng)批判性思維能力，并在線(xiàn)上和線(xiàn)下生活之間找到平衡）相符。因此，B選項(xiàng)是正確的。第二部分1.C解析思路：根據(jù)文章第一段“WhileAIoffersnumerouspotentialbenefits,suchasincreasedefficiency,productivity,andinnovation,italsoraisesconcernsaboutjobdisplacement,ethicalimplications,andthepotentialformisuse.”可知，人工智能提供了許多潛在的好處，如提高效率、生產(chǎn)力和創(chuàng)新，但也引發(fā)了關(guān)于工作流失、道德含義和潛在濫用的擔(dān)憂(yōu)。因此，C選項(xiàng)（人工智能對(duì)工作場(chǎng)所的一個(gè)主要影響是它有可能導(dǎo)致工作流失）是對(duì)第一段內(nèi)容的準(zhǔn)確概括。2.D解析思路：根據(jù)文章第二段“However,AIisalsocreatingnewjobopportunities.Thedevelopment,implementation,andmaintenanceofAIsystemsrequireagrowingworkforcewithskillsinareassuchasdatascience,machinelearning,androbotics.Additionally,AIisenablingthecreationofnewproductsandservicesthatdidnotexistbefore,openingupentirelynewindustriesandjobcategories.”可知，人工智能也在創(chuàng)造新的工作機(jī)會(huì)。人工智能系統(tǒng)的發(fā)展、實(shí)施和維護(hù)需要越來(lái)越多的勞動(dòng)力，這些勞動(dòng)力需要在數(shù)據(jù)科學(xué)、機(jī)器學(xué)習(xí)和機(jī)器人技術(shù)等領(lǐng)域擁有技能。此外，人工智能正在促進(jìn)新產(chǎn)品的和服務(wù)創(chuàng)造，這開(kāi)辟了全新的產(chǎn)業(yè)和職業(yè)類(lèi)別。因此，D選項(xiàng)（人工智能正在創(chuàng)造新的工作機(jī)會(huì)，包括數(shù)據(jù)科學(xué)家和機(jī)器人工程師）是對(duì)第二段內(nèi)容的準(zhǔn)確概括。3.A解析思路：根據(jù)文章第三段“EthicalconcernssurroundingAIarealsoincreasinglyprominent.Issuessuchasalgorithmicbias,privacyviolations,andthepotentialformisuseofAItechnologyposesignificantchallenges.”可知，圍繞人工智能的道德問(wèn)題也越來(lái)越突出。算法偏見(jiàn)、隱私侵犯以及人工智能技術(shù)被濫用的可能性等問(wèn)題都提出了重大挑戰(zhàn)。因此，A選項(xiàng)（人工智能在道德方面的一個(gè)主要問(wèn)題是算法偏見(jiàn)和隱私侵犯）是對(duì)第三段內(nèi)容的準(zhǔn)確概括。4.D解析思路：根據(jù)文章第四段“Finally,thepotentialformisuseofAIisasignificantconcern.AItechnologycouldbeusedformaliciouspurposes,suchasdevelopingautonomousweaponssystemsorengagingincyberattacks.ThedevelopmentofAIweaponsraisesethicalquestionsabouttheacceptableuseofforceandthepotentialforunintendedconsequences.”可知，人工智能被濫用的可能性是一個(gè)重大問(wèn)題。人工智能技術(shù)可能被用于惡意目的，例如開(kāi)發(fā)自主武器系統(tǒng)或進(jìn)行網(wǎng)絡(luò)攻擊。人工智能武器的開(kāi)發(fā)引發(fā)了關(guān)于可接受使用武力和意外后果潛在性的道德問(wèn)題。因此，D選項(xiàng)（人工智能有可能被用于惡意目的，例如開(kāi)發(fā)自主武器系統(tǒng)）是對(duì)第四段內(nèi)容的準(zhǔn)確概括。5.B解析思路：文章最后一段指出“thekeyistouseitresponsiblyandtobeawareofitspotentialnegativeimpacts.Weneedtodevelopcriticalthinkingskillstodistinguishbetweenreliableandunreliableinformation,andweneedtofindabalancebetweenouronlineandofflinelives.”（關(guān)鍵是要負(fù)責(zé)任地使用它，并意識(shí)到其潛在的負(fù)面影響。我們需要培養(yǎng)批判性思維能力，以區(qū)分可靠和不可靠的信息，并在我們的線(xiàn)上和線(xiàn)下生活之間找到平衡。）這與B選項(xiàng)（我們需要負(fù)責(zé)任地使用人工智能，并制定國(guó)際規(guī)范來(lái)防止其被濫用）相符。因此，B選項(xiàng)是正確的。第三部分1.B解析思路：根據(jù)文章首段“Climatechangeisoneofthemostsignificantchallengesfacinghumanitytoday.Theincreasingconcentrationofgreenhousegasesintheatmosphere,primarilyduetohumanactivitiessuchasburningfossilfuelsanddeforestation,iscausingtheEarth'saveragetemperaturetoriseatanunprecedentedrate.”可知，氣候變化是人類(lèi)今天面臨的最重大挑戰(zhàn)之一。大氣中溫室氣體的濃度不斷增加，主要由于人類(lèi)活動(dòng)，如燃燒化石燃料和砍伐森林，導(dǎo)致地球平均溫度以前所未有的速度上升。因此，B選項(xiàng)（人類(lèi)活動(dòng)導(dǎo)致大氣中溫室氣體濃度增加，地球平均溫度上升）是對(duì)首段內(nèi)容的準(zhǔn)確概括。2.D解析思路：根據(jù)文章第二段“Oneofthemostimmediateandvisibleimpactsofclimatechangeistheincreasingfrequencyandseverityofextremeweatherevents.Heatwaves,droughts,floods,andhurricanesarebecomingmorecommonandmoreintense,causingsignificantdamagetoproperty,infrastructure,andecosystems.”可知，氣候變化最直接和可見(jiàn)的影響是極端天氣事件（如熱浪、干旱、洪水和颶風(fēng)）的頻率和嚴(yán)重性不斷增加。這些事件對(duì)財(cái)產(chǎn)、基礎(chǔ)設(shè)施和生態(tài)系統(tǒng)造成重大損害。因此，D選項(xiàng)（導(dǎo)致極端天氣事件如熱浪、干旱、洪水和颶風(fēng)的頻率和嚴(yán)重
