B.Imitated.C.Resembled. D.Pretended.解析B詞義揣測題。由第四段中的"Withthisknowledge,Sarahbegantodesignairplanesthatincorporatedbiomimicry,ortheimitationofnature"可推知,mimicked與句中的imitation意義相通,故選B項。3.WhatisoneexampleofbiomimicryinSarah’sairplanedesigns?A.Wingsthatadjusttheirshapebasedonwindconditions.B.Enginesthatrunonrenewableenergysources.C.Cockpitsthatmimicthestructureofabird’snest.D.Landingdevicesthatresembleinsectlegs.解析A微小環(huán)節(jié)理解題。由第四段中的"Shecreatedwingsthatcouldadjusttheirshapebasedonwindconditions,justlikeabird’swings"可知,本題選A項。4.WhatcanwelearnabouttheairplanesdesignedbySarahLeefromthetext?A.Theywerenotthatpopularasexpectedatfirst.B.Theyranonsustainableenergycompletely.C.Theycouldholdmuchmorepassengersthanformerairplanes.D.Theycausedlesspollutiontotheenvironmentthanformerairplanes.解析D微小環(huán)節(jié)理解題。由第五段中的"Theyusedlessfuelandemittedfewerpollutantsintotheair"可知,本題選D項。C[2024遼寧沈陽市郊聯(lián)體考試]Thereisnolackofexcellentflyingbuilders—suchasbees—innature.Tobuildanest,theseinsectsteamuptocollecttheneededmaterialsandfollowthespecificationofacomplexdesignthatendsupbeingmanytimestheirsize.Thisbuildingprocesstakesmonths,evenlongerthantheiraveragelifespan,duringwhichtheinsectsmustadjustastheygo.Inspiredbytheseinsectbuildingteams,MirkoKovac,aroboticist,developedawaytoimprove3Dprintingfortheconstructionindustry.Atypical3Dprinterislimitedbytherangeofitsnozzle(噴嘴),andcanonlymakeobjectssmallerthanitself.Besides,3Dconstructionroboticscurrentlyfocusesmostlyonground-basedrobots.Andlarge-scalesystemsthatneedtobeconnectedtoapowersupplyarelimitedinplaceswheretheycanbelaidout.DrKovac’steamhasremovedtheselimitationsbygivingtheprinternozzlewings.DrKovacdescribesasystemofflyingrobotsthatiscomposedoftwotypesofdrones:BuilDronesandScanDrones.First,abuilderfliesoveritsareaofoperationandbeginstoreleaseajetofthebuildingmaterial.Oncethebuilderrobothassprayedalayerofmaterial,thescannerrobotfliesoverandinspectstheprogress.Thescannerthencalculatesthenextlayerthatthebuildershouldmake,whilealsocorrectinganyerrorsthatmighthavebeendiscoveredinwhathasalreadybeenbuilt.Atthispoint,peoplecanalsostepintheprocesswhennecessary.Theresearcherstestedthesystem’scapabilitiesbybuildingbothalargecylinder(圓柱體)(72layersand2meterstall)madeofalightweightmaterial,andasmallone(28layers,18cm)madeofahigh-densitymixture.Thetaskswerenotsimple.Makingcirclesontopofothercircleswouldnothaveworked,becausetheperfectalignmentrequiredwouldhavebeenimpracticaltoachieve.Asaresult,DrKovac’srobotspassedthetestwithflyingcolors—thecylinderswerebuilttowithin5mmofthewidthandheightoftheplannedstructures,whichisofsufficientquality,asfarasBritishbuildingrequirementsareconcerned.Becausetheflyingrobotscan,intheory,operateanywhere,theycouldfixthingsindangerousorotherwiseinaccessibleplaces.本文是一篇說明文。文章主要介紹了一個機器人專家受到了蜜蜂的啟發(fā)建立機器人的過程以及該機器人潛在的應用。1.Whatisthedisadvantageofconventional3Dconstructionrobots?A.Theylackflexibility.B.They’reelectricity-consuming.C.They’rehardtosetupandoperate.D.Theymakenozzlessubjecttowearandtear.解析A推理推斷題。由其次段中的"Atypical3Dprinterislimitedbytherangeofitsnozzle(噴嘴),andcanonlymakeobjectssmallerthanitself.Besides,3Dconstructionroboticscurrentlyfocusesmostlyonground-basedrobots.Andlarge-scalesystemsthatneedtobeconnectedtoapowersupplyarelimitedinplaceswheretheycanbelaidout"可知,本題選A。2.WhatareScanDronesresponsiblefor?A.Spreadingbuildingmaterialslayerbylayer.B.Monitoringthebuildingprocessinrealtime.C.Warninghumanoperatorsofpotentialerrors.D.SupplyingBuilDroneswithbuildingmaterials.解析B微小環(huán)節(jié)理解題。由第四段中的"Oncethebuilderrobothassprayedalayerofmaterial,thescannerrobotfliesoverandinspectstheprogress"可知,ScanDrones負責實時監(jiān)控建筑過程,故選B。3.Howdidtheresearchersfindtheirinnovation?A.Confusing.
