大题03阅读理解说明文说明文所选材料题材丰富多样，涉及社会、科技、文化、生活、人物、教育、生态、安全等方面。在高考英语阅读理解中，说明文所占比重尤为突出。它既要求考生能熟练运用词汇和语法知识、理解文章语句、把握语篇整体结构，还要求学生有大量的阅读积淀和知识储备，熟悉不同的话题和不同的题目考查方式。即便是细节理解题，大多数情况下考生也无法从文章中直接找到与选项表述完全一致的信息，而是需要在理解文章细节信息后作出归纳和判断。通常一套卷中主旨大意、词义猜测、写作意图/观点态度类高难度试题的考查数量为2道左右，说明文考查此类题目的频率较高，且命题点呈多样化。（2023年新高考I卷D篇）0nMarch7,1907,theEnglishstatisticianFrancisGaltonpublishedapaperwhichillustratedwhathascometobeknownasthet4wisdomofcrowdseffect.Theexperimentofestimationheconductedshowedthatinsomecases,theaverageofalargenumberofindependentestimatescouldbequiteaccurate.Thiseffectcapitalizesonthefactthatwhenpeoplemakeerrors,thoseerrorsaren,talwaysthesame.Somepeoplewilltendtooverestimate,andsometounderestimate.Whenenoughoftheseerrorsareaveragedtogether,theycanceleachotherout,resultinginamoreaccurateestimate.Ifpeoplearesimilarandtendtomakethesameerrors,thentheirerrorswon'tcanceleachotherout.Inmoretechnicalterms,thewisdomofcrowdsrequiresthatpeople,sestimatesbeindependent.Ifforwhateverreasons,people'serrorsbecomecorrelatedordependent,theaccuracyoftheestimatewillgodown.ButanewstudyledbyJoaquinNavajasofferedaninterestingtwist（转折）onthisclassicphenomenon.Thekeyfindingofthestudywasthatwhencrowdswerefurtherdividedintosmallergroupsthatwereallowedtohaveadiscussion,theaveragesfromthesegroupsweremoreaccuratethanthosefromanequalnumberofindependentindividuals.Forinstance,theaverageobtainedfromtheestimatesoffourdiscussiongroupsoffivewassignificantlymoreaccuratethantheaverageobtainedfrom20independentindividuals.Inafbllow-upstudywith100universitystudents,theresearcherstriedtogetabettersenseofwhatthegroupmembersactuallydidintheirdiscussion.Didtheytendtogowiththosemostconfidentabouttheirestimates?Didtheyfollowthoseleastwillingtochangetheirminds?Thishappenedsomeofthetime,butitwasn'tthedominantresponse.Mostfrequently,thegroupsreportedthatthey“sharedargumentsandreasonedtogether,Somehow,theseargumentsandreasoningresultedinaglobalreductioninerror.AlthoughthestudiesledbyNavajashavelimitationsandmanyquestionsremain,thepotentialimplicationsforgroupdiscussionanddecision-makingareenormous.28.
