B.Stand.C.Avoid. D.Fail.解析B词义揣测题。由画线词所在句的"whilemanymodernconcretestructuresseemtofallapartafterafewdecades"可知,此处while表示前后两种状况的对比,画线词应与fallapart意思相反。很多现代混凝土结构好像在几十年后就会瓦解,而古罗马建筑可以经得住时间的考验。由此可推知,画线词意为"经受住",与stand意思一样,故选B项。3.Whatdoweknowabouttheself-healingprocess?A.Thelimeitselfcouldfillthecracklater.B.Thequicklimeshouldbemadeonrainydays.C.Thechemicalfoundationcouldweakentheconcrete.D.Combiningwaterandquicklimewouldproduceheat.解析D微小环节理解题。由第四段中的"theyintroducedwaterinto...thatcouldstrengthentheconcretelater"可知,他们在搅拌过程中将水加到了生石灰中,它所产生的热量形成了一种随后可以强化混凝土的化学基础。由此可知,将水和生石灰混合会产生热量,故选D项。4.WhatcanbeinferredfromRamirez’swords?A.Peoplecanbeinspiredtomakegreenermaterials.B.ThesecretofRomanconcreteishiddeninabottle.C.Romanconcretehasgreatlyimprovedtheenvironment.D.Romanconcreteispopularinmakingmodernarchitecture.解析A推理推断题。由最终一段Ramirez的话可知,对古罗马混凝土的新理解让我们了解了一种使材料更加环保的方式。古罗马人制造了这种材料,我们必需弄清晰他们是如何做到的,这样我们才能制作更好的材料,反过来成为更好的环境疼惜者。换句话说,我们可以从古罗马人制作的这种材料中吸取灵感,去独创更环保的材料,故选A项。B[2024南京六校调研]Theworldmayhaveanewsupercontinentwithin200millionto300millionyearsasthePacificOceanshrinksandcloses.ResearchersatCurtinUniversityinAustraliaandPekingUniversityinChinausedasupercomputertomodeltheevolutionofEarth’stectonicplates(地壳构造板块)andtheformationofafuturesupercontinent.TheirfindingswerepublishedinthejournalNationalScienceReview."Overthepasttwobillionyears,Earth’scontinentshavecollided(相撞)togethertoformasupercontinentevery600millionyears,knownasthesupercontinentcycle.Thismeansthatcurrentcontinentsareduetocometogetheragaininacoupleofhundredmillionyears’time,"saidleadauthorDr.ChuanHuang,aresearchfellowinCurtin’sEarthDynamicsResearchGroupandtheSchoolofEarthandPlanetarySciences.Theteam’ssimulationshowedthatduetothefactthatEarthhasbeencoolingforbillionsofyearssinceitsformation,thethicknessandstrengthofthetectonicplatesbeneaththeoceanshavereducedovertime.Asaresult,theformationofanewsupercontinentismorelikelytohappenbytheclosingupofthePacificOcean.Reducedbyafewcentimetersperyear,thePacificOcean’scurrentreachof10,000kilometerswillcloseupinlessthan300millionyears."TheresultingnewsupercontinenthasalreadybeennamedAmasiabecausesomebelievethatthePacificOceanwillclosewhenAmericacollideswithAsia.AustraliaisalsoexpectedtoplayaroleinthisimportantEarthevent,firstcollidingwithAsiaandthenconnectingAmericaandAsiaoncethePacificOceancloses,"Huangsaid.Changesinthedistributionofcontinentsandoceanswillcausechangesinclimates,"particularlywhenoceancurrentsarestoppedbycontinentalcollision,ornewoceancurrentsareformedwhencontinentsbreakapart,"saidstudyco-authorZheng-XiangLi,distinguishedprofessorinCurtin’sSchoolofEarthandPlanetarySciences."Earth,asweknow,willbecompletelydifferentwhenAmasiaforms.Sealevelisexpectedtobelower,andthevastinteriorofthesupercontinentwillbeverydrywithhighdailytemperatureranges."Researchersexpectmoreearthquakesasthecontinentalplatescollide.Surroundedbyanewsuperocean,thenewlyformedsupercontinentwillalsohavedecreasedbiodiversity.ScientistsarestilltryingtounderstandEarth’ssupercontinentcycle,whichisdrivenbyheatandgravity.TheresearchteamwantstoestablishhowEarth’stectonicplatesstartedandwhenthefirstcontinentsformed,aswellaswhatkickedoffthesupercontinentcycle."WeareonlystartingtolookattheentireEarthsystem,fromitscoretoitsatmosphere,asacloselylinkedsystemthatevolvedtogether,"Lisaid.随着太平洋的缩小和闭合,在2亿至3亿年内世界上可能会出现一个新的超大陆。探讨人员运用超级计算机模拟了地球地壳构造板块的演化以及将来超大陆的形成。【词语积累】shrinkv.缩小evolutionn.进化simulationn.模拟interiorn.内陆;内部kickoff起先【熟词生义】plate常用义:n.盘子;碟子文中义:n.板块1.Whatleadstotheformationofthenewsupercontinent?A.TherisingtemperatureofEarth.B.TheexpansionofthePacificOcean.C.Thereducedstrengthofthetectonicplates.D.Theappearanceofmanynewtectonicplates.解析C微小环节理解题。由第四段中的"Earthhasbeencoolingforbillionsofyears...bytheclosingupofthePacificOcean"可知,地球自形成以来已经冷却了数十亿年,海洋下的地壳构造板块的厚度和强度随着时间的推移而减小。因此,一个新的超大陆的形成更有可能发生在太平洋闭合的时候,故选C项。2.Whatisbelievedbysomescientistsaboutthenewsupercontinent?A.Theinvolvingparts.B.Itsclimatepattern.C.Thewayitbreaksapart.D.ItsdistancefromAustralia.解析A微小环节理解题。由第五段中的"somebelievethatthePacificOceanwillclose...oncethePacificOceancloses"可知,一些人猜想当美洲与亚洲相撞时,太平洋将闭合。澳大利亚大陆预料也会在这一重要的地球事务中发挥作用,它会首先与亚洲相撞,然后在太平洋闭合时连接美洲和亚洲。由此可知,一些科学家猜想新的超大陆应当包含很多部分,故选A项。3.Whatwillprobablyhappentothenewlyformedsupercontinent?A.Therewillbeariseinsealevel.B.Therewillbelotsofwaterintheinterior.C.Thevarietyofitslivingthingswillbereduced.D.Itstemperaturewillstaythesameallyearround.解析C微小环节理解题。由倒数其次段中的"Surroundedbyanewsuperocean,thenewlyformedsupercontinentwillalsohavedecreasedbiodiversity"可知,新形成的超大陆被一个新的超级海洋包围,生物多样性也将削减,故选C项。4.Whatdoesthelastparagraphmainlywanttoshow?A.TheentireEarthsystemfacesanuncertainfuture.B.Theoriginofthesupercontinentcycleishardtotrace.C.Earth’ssupercontinentcyclewillposeabigthreat.D.Thereismoretodiscoveraboutthesupercontinentcycle.解析D段落大意题。最终一段讲科学家们仍在试图了解地球的超大陆周期,它是由热量和重力驱动的。探讨团队希望确定地球的地壳构造板块是如何出现的,第一批大陆是何时形成的,以及什么开启了超大陆周期。由此可知,最终一段主要想说明"关于超大陆周期还有更多的东西待发觉",故选D项。C[2024浙江杭州高三一模]Thatdinosaursatethemammals(哺乳动物)thatranbeneaththeirfeetisnotindoubt.NowanextraordinaryfossilnewlydescribedinScientificReports
