consumers,thegigeconomyoffersgreaterchoiceandoftenlowerpricesforgoodsandservices.Thecompetitionamonggigworkersvyingforcustomersencouragesefficiencyandinnovation,leadingtobetterserviceandlowercosts.”指出競爭促使效率和創(chuàng)新，進(jìn)而帶來更好服務(wù)和更低價格，這對消費(fèi)者是積極影響。3.零工經(jīng)濟(jì)對勞動者構(gòu)成的主要挑戰(zhàn)是：缺乏傳統(tǒng)雇員享有的工作保障和福利，導(dǎo)致收入不穩(wěn)定。*解析思路：根據(jù)文章第三段，“Onemajorconcernisthelackofjobsecurityandbenefitsthattraditionalemployeesenjoy...Thelackofsecuritycanleavegigworkersvulnerabletoeconomicinstabilityandplaceaburdenonsocialsafetynets.Additionally,thenatureofgigworkofteninvolvesunpredictableincome...”明確指出零工經(jīng)濟(jì)的主要挑戰(zhàn)在于缺乏工作保障、福利以及收入的不穩(wěn)定性。4.平臺公司可能剝削零工經(jīng)濟(jì)勞動者的一個方式是：利用算法進(jìn)行管理，優(yōu)先考慮最大化利潤，有時會降低工資或任意取消任務(wù)。*解析思路：根據(jù)文章第三段，“Thepowerimbalancebetweenplatformcompaniesandgigworkerscanleadtounfairpracticessuchaslowpay,arbitrarycancellationofgigs...Thealgorithmicmanagementofgigworkcanalsocontributetoexploitation,asplatformsmayprioritizemaximizingprofitsoverensuringfairwagesandworkingconditions.”指出平臺利用其權(quán)力地位和不公平的算法管理來剝削勞動者，可能表現(xiàn)為低工資、任意取消任務(wù)等。5.文章認(rèn)為政策制定者應(yīng)解決的主要問題是：如何在保護(hù)零工經(jīng)濟(jì)勞動者權(quán)益的同時，促進(jìn)該經(jīng)濟(jì)模式的創(chuàng)新活力。*解析思路：文章最后一段指出，“Policymakersneedtocarefullyconsiderthesechallengesanddevelopregulationsthatprotectgigworkerswhilestillfosteringtheinnovationanddynamismofthegigeconomy.”明確提出了政策制定者面臨的挑戰(zhàn)是既要保護(hù)勞動者，又要促進(jìn)創(chuàng)新。該選項準(zhǔn)確概括了政策制定者需要解決的問題。第三篇文章1.本段的主要觀點是：人工智能在自動化工作的同時，也可能創(chuàng)造新的工作崗位和行業(yè)，或增強(qiáng)人類能力。*解析思路：該段首先提出AI可能自動化工作崗位（導(dǎo)致失業(yè)），然后轉(zhuǎn)折指出AI也可能創(chuàng)造新崗位、增強(qiáng)人類能力。因此，該段的核心觀點是AI對工作影響的兩個方面：潛在的負(fù)面（自動化）和正面（創(chuàng)造新崗位、增強(qiáng)能力）。2.為了應(yīng)對人工智能對未來工作的影響，社會在教育方面應(yīng)采取的關(guān)鍵措施是：提供持續(xù)的教育和培訓(xùn)，幫助工人更新技能以適應(yīng)不斷變化的工作要求。*解析思路：根據(jù)文章第四段，“Educationandtrainingwillplayacrucialroleinpreparingworkersforthejobsofthefuture.AsAIcontinuestoevolve,theskillsrequiredintheworkforcewillchange,andworkerswillneedtocontinuouslyupdatetheirskills...Thiswillrequiresignificantinvestmentineducationandtrainingprograms...”明確強(qiáng)調(diào)教育培訓(xùn)在適應(yīng)AI變化
