B．Possible.C．Tough. D．Different.C詞義猜測題。根據(jù)畫線詞所在句中的“Geneticdifferencesbetweenthetwobirdspeciesarethereforemuchgreater”可知，渡渡鳥和尼科巴鴿子差異非常大，由此可推知，復(fù)活渡渡鳥是艱巨的任務(wù)，畫線詞與tough意思相近，意為“艱難的”。4．WhatisShapiro'sattitudetowardstherebirthofdodos?A．Favorable. B．Intolerant.C．Objective. D．Negative.D觀點(diǎn)態(tài)度題。通讀全文可知，文章介紹了復(fù)活渡渡鳥的種種困難，由此可推知，夏皮羅對復(fù)活渡渡鳥持消極的態(tài)度。B(2024·株洲一模)SittingatthetopofamountainonLaGomeraIsland,Antonioissuedaninvitationtothreevisitinghikersinthedistance—“Comeoverhere.We'regoingtotreatyoutolunch.”—withoutspeakingword：Hewhistled(吹口哨)it.Antonio,71,saidinhisyouth,whennativesratherthantouristswalkedtherockyfootpathsofhisisland,hisnewswouldhavebeengreetedrightawaybyarespondingwhistle,loudandclear.Buthismessagewaslostonthesehikers,andtheycontinuedtheirjourney.AntonioisaproudguardianofLaGomera'swhistlinglanguage,whichhecalled“thepoetryofmyisland”.Headded，“Likepoetry,whistlingdoesnotneedtobeusefulinordertobespecialandbeautiful.”Thelanguage,officiallyknownasSilboGomero,replaceswrittenletterswithwhistledsoundsthatvarybypitch(高音)andlength.Unfortunately,therearefewerwhistlesthanSpanishletters,soasoundcanhavemultiplemeanings,causingmisunderstandings.Withitsdistinctgeography,it'seasytoseewhywhistlingcameintoexistenceonLaGomera.Onmostoftheisland,deepvalleysrunfromhighpeaksdowntotheocean,andplentyoftimeandeffortarerequiredtotravelevenashortdistanceoverland.Whistlingdevelopedasagoodalternativewaytodeliveramessage,withitssoundcarryingfartherthanshouting—asmuchastwomilesacrosssomevalleyswithfavorablewindconditions.In2009,theisland'slanguagewasaddedbyUNESCOtoitslistoftheIntangibleCulturalHeritageofHumanity.Butwithwhistlingnolongeressentialforcommunication,SilboGomero'ssurvivalmostlyreliesona1999lawthathasmadeteachingitanecessarypartofLaGomera'sschoolcourses.ErinGerhards,alocalgirlkeentoimproveherwhistling,said，“Whistlingisawaytohonorthepeoplethatlivedhereinthepastandtorememberwedidn'tstartwithtechnologybutsimplebeginnings.”【語篇解讀】本文是一篇說明文。文章介紹了拉戈梅拉島哨語。5．HowdidthehikersreacttoAntonio'sinvitation?A．Theyignoredit.B．Theywavedtheirhands.C．Theywhistledback.D．Theystoppedsuddenly.A細(xì)節(jié)理解題。根據(jù)第一段中的“Buthismessagewaslostonthesehikers,andtheycontinuedtheirjourney.”可知，徒步旅行者無視了安東尼奧的邀請。6．WhyisLaGomera'swhistlinglanguagelikelytobemisinterpreted?A．Becauseitisaformofpoetry.B．Becausethesamesoundcarriesdifferentmeanings.C．Becauseitisn'tusefulinlife.D．Becauseitssoundsincludevariouspitchesandlengths.B細(xì)節(jié)理解題。根據(jù)第二段最后一句可知，因?yàn)樯谝舻臄?shù)量比西班牙字母要少，所以一個(gè)聲音可能有多種含義，從而導(dǎo)致誤解。7．Whatisparagraph3mainlyabout?A．ThetouristattractionsofLaGomera.B．ThegeographicfeaturesofLaGomera.C．Thereasonforwhistling'suseonLaGomera.D．Thecomparisonbetweenwhistlingandshouting.C段落大意題。根據(jù)第三段內(nèi)容尤其是第一句可知，本段主要講述了在拉戈梅拉島上使用哨語的原因。8．Whatcanbeinferredfromparagraph4?A．Erinfiguresouthowislanderslivedbefore.B．SilboGomeroistaughtinLaGomera'sschools.C．TechnologyoutweighstraditionsonLaGomera.D．SilboGomeroisimportantindailyconversations.B推理判斷題。根據(jù)第四段中的“SilboGomero'ssurvivalmostly...schoolcourses”可知，法律規(guī)定將哨語作為拉戈梅拉學(xué)校課程的必要組成部分。由此可推知，拉戈梅拉島的學(xué)校教授哨語。C(2024·廣州三校聯(lián)考)Researchershavesuccessfullychangedthebloodtypeofadonatedhumanlungbytreatingitwithenzymes(酶),markinganimportantsteptowardsmakinguniversaldonororgans.Bloodtypesarelargelydefinedbythepresenceorabsenceofcertainsugarmolecules(分子)calledantigensonthesurfaceofcells.Thesecanoccurnotjustonthecellsoftheblooditself,butothertissues.Ifanantigenisn'trecognizedbythebody'simmunesystem,itwillmountanattackonthesecells.Thisleadstotherejectionoftransplantedorgansfromadonorwithadifferentbloodtype.Peoplewiththemostcommonbloodtype,O,lacktheseantigensontheircells,sotheirorganscanbeacceptedbypeoplewithotherbloodtypes.IfalldonororganscouldbemadetypeO,forexample,thelungsfromsomeonewithbloodtypeA,thiscouldbebeneficial.Totrythis,Cypelandhisteamusedapairofenzymesinthehumanstomachtodigestsugars.Theyfoundtheenzymescouldremove97percentoftypeAantigensinthelungsfromatypeAdonorin4hours,whichmeantthecellshadbeeneffectivelychangedtobloodtypeO.Afterthistreatment,thealteredlungswerekeptaliveusingasystemknownasex-vivolungperfusion(離體肺灌注),whichsuppliesorganswithnutritiousfluidsotheyarereadyfortransplantation.Tosimulateatransplant,Cypel'steamaddedtypeOblood,whichcontainsantibodiesthatwouldattacktypeAantigens,tothefluidsupplyingthelungs.Thetreatedlungshadminimalantibodydamagecomparedwithuntreatedlungs.Althoughcellsridofantigenstendtoproducenewonesovertime,Cypelhopesthelackofantigenswouldlastlongenoughforthebodytogetthroughthedangerousfirstfewdaysandweeksafteratransplant.Theteamnowintendstotesttheprocedureinanimals.Thestudyonlylookedattheeffectsofasimulatedtransplantationovertheshortterm,whichisn'tenoughtoassesswhethertheresurfacedantigenscouldeventuallyhaveanegativeeffect.【語篇解讀】本文是一篇說明文。文章介紹了通過改變血型的方式使得器官捐贈(zèng)更為普遍。9．Whichofthefollowingmaydecidethebloodtypeofaperson?A．Sugar. B．Enzymes.C．Antibody. D．Antigens.D細(xì)節(jié)理解題。根據(jù)第二段中的“Bloodtypesarelargelydefined...antigensonthesurfaceofcells.”可知，血型主要是由細(xì)胞表面有無抗原來界定的。10．Whyshouldthebloodtypeofthedonor
