rhalos.*解析思路：文章第一段通過兩個(gè)主要例子說明了暗物質(zhì)存在的證據(jù)。一是星系旋轉(zhuǎn)速度快于可見物質(zhì)所能解釋的范圍，二是圍繞巨大星系的引力透鏡效應(yīng)。這些都是暗物質(zhì)通過引力作用對(duì)可見物質(zhì)產(chǎn)生影響的體現(xiàn)。8.TwotheoreticalmodelsmentionedaretheWeaklyInteractingMassiveParticle(WIMP),whichisexpectedtoannihilateordecayintoStandardModelparticles,andaxions,whichareanothercandidateparticletype.*解析思路：文章第二段介紹了兩種主要的暗物質(zhì)候選理論模型。第一種是弱相互作用大質(zhì)量粒子（WIMP），它預(yù)計(jì)會(huì)湮滅或衰變成標(biāo)準(zhǔn)模型粒子。第二種是軸子（axion），是另一種候選粒子類型。9.Advancementsinastronomicalobservationtechniquesmentionedincludegravitationalwaveastronomy,whichoffersanewwindowintotheuniversepotentiallyallowingscientiststoprobedarkmatterinteractions,andlarge-scalesurveysmappingthedistributionofgalaxiesandthecosmicwebtorevealdarkmatterhalosanddeterminetheirdensityprofiles.*解析思路：文章第三段提到了兩種主要的觀測(cè)技術(shù)進(jìn)步。一是引力波天文學(xué)，它為宇宙提供了一個(gè)新的窗口，可能允許科學(xué)家探測(cè)暗物質(zhì)相互作用。二是大規(guī)模調(diào)查，繪制星系和宇宙網(wǎng)的分布，以揭示暗物質(zhì)暈并確定其密度分布。10.ThedirectdetectionofdarkmatterwouldconfirmtheexistenceofanewclassofparticlesbeyondtheStandardModelofparticlephysics,openingupentirelynewfieldsofstudy,andunderstandingdarkmattercouldshedlightonthenatureoftheuniverseitself,includingitsorigins,evolution,andultimatefate.*解析思路：文章最后一段指出了直接探測(cè)到暗物質(zhì)的潛在影響。首先，它會(huì)證實(shí)標(biāo)準(zhǔn)模型粒子之外的全新粒子類的存在，開辟全新的研究領(lǐng)域。其次，理解暗物質(zhì)有助于闡明宇宙本身的性質(zhì)，包括其起源、演化和最終命運(yùn)。C11.Theprimaryadvantageshighlightedbyproponentsareflexibility,allowingindividualstochoosetheirprojects,settheirownhours,andpotentiallyearnhigherincomesbasedontheirskillsandeffort,andagilityforbusinesses,allowingforscalinglaborupordownbasedondemand.*解析思路：文章第一段明確闡述了支持者的觀點(diǎn)，主要優(yōu)勢(shì)在于靈活性，允許個(gè)人選擇項(xiàng)目、設(shè)定自己的時(shí)間，并可能根據(jù)技能和努力獲得更高的收入；以及對(duì)企業(yè)來說的敏捷性，允許根據(jù)需求擴(kuò)大或縮小勞動(dòng)力規(guī)模。12.Accordingtothepassage,disadvantagesorchallengesfacedbygigworkersincludelackofsecurityandbenefitsassociatedwithtraditionalemployment,suchashealthinsurance,paidsickleave,andretirementplans,financialinstabilityduetoinconsistentgigincome,isolation,lackofcareerprogression,minimalsocialinteractioncomparedtoofficeenvironments,andconcernsaboutfaircompensation,dataprivacy,andworkerrightsduetothepowerimbalancebetweenplatformcompaniesandindividualworkers.*解析思路：文章第二段詳細(xì)列舉了零工工作者的劣勢(shì)和挑戰(zhàn)，包括缺乏傳統(tǒng)就業(yè)相關(guān)的安全感和福利（如健康保險(xiǎn)、帶薪病假、退休計(jì)劃），由于收入不穩(wěn)定導(dǎo)致的經(jīng)濟(jì)不安全感，與辦公室環(huán)境相比社交互動(dòng)較少，以及由于平臺(tái)公司與個(gè)人勞動(dòng)者之間的權(quán)力不平衡，對(duì)公平報(bào)酬、數(shù)據(jù)隱私和勞動(dòng)者權(quán)利的擔(dān)憂。13.Themainpointofcontentionregardingtheclassificationofgigworkersiswhethertheyshouldbeclassifiedasemployeesorindependentcontractors,withsignificantimplicationsfortheirlegalprotections,benefits,andrelationshipwiththeplatform.*解析思路：文章第二段末尾和第三段都提到了關(guān)于零工工作者分類的主要爭議點(diǎn)，即他們應(yīng)該是被歸類為雇員還是獨(dú)立承包商，這對(duì)他們的法律保護(hù)、福利以及與平臺(tái)的關(guān)系都有重大影響。14.Policyresponsestothegigeconomymentionedincludeattemptsbysomejurisdictionstoextendcertainlaborprotections,suchasminimumwagelawsorpaidleaverequirements,togigworkers;creationofspecificsocialsafetynetstailoredtonon-traditionalemploymentarrangements;platformcompaniesexploringvariousmodelstoprovidesomebenefits,suchasportablehealthinsuranceoptionsorprofit-sharingprograms;anddesigningregulationsthatprotectworkerswithoutstiflinginnovation.*解析思路：文章第三段概述了針對(duì)零工經(jīng)濟(jì)的政策應(yīng)對(duì)措施，包括一些地區(qū)試圖將某些勞動(dòng)保護(hù)（如最低工資法或帶薪休假要求）擴(kuò)展到零工工作者；為非傳統(tǒng)就業(yè)安排創(chuàng)建特定的社會(huì)保障網(wǎng)；平臺(tái)公司探索提供某些福利（如可攜帶的健康保險(xiǎn)選項(xiàng)或利潤分享計(jì)劃）的various模式；以及設(shè)計(jì)既能保護(hù)工人又不會(huì)扼殺創(chuàng)新的法規(guī)。15.Themainuncertaintyorongoingdebatementionedaboutthelong-termimpactofthegigeconomyisitsoveralleffectonlaborstandards,socialcohesion,andthefutureofwork.*解析思路：文章第四段最后一句提出了關(guān)于零工經(jīng)濟(jì)長期影響的主要不確定性和持續(xù)爭
