D．Itchallengestraditionalmoralvalues.【答案】12．B13．D14．A15．C【解析】這是一篇說明文。主要介紹了太空旅行中冬眠的理論及其研究進展。12．推理判斷題。根據(jù)第一段中“However,somethinggoeswrongandJimandAurorawakeup90yearstooearly.ButwhatifwetoldyouthathibernationforspacetravelismorelikelytohappenthantheromanticstorybetweenJimandAurora?(然而，事情出了問題，吉姆和奧羅拉提前90年醒來。但如果我們告訴你，太空旅行的冬眠比吉姆和奧羅拉之間的浪漫故事更有可能發(fā)生呢？)”可推知，作者提到電影《太空旅客》是為了引出下文關(guān)于太空旅行中冬眠這一話題，介紹一種長途太空飛行的新方法（Tointroduceanewapproachtolongspaceflights）。故選B項。13．推理判斷題。根據(jù)第三段“ForgoingtoMars,astronautswouldrequireabout30kgoffood,water,air,andothersuppliesperday.Thus,hibernationcansignificantlycutdownontheiressentialneeds.Additionally,hibernatingastronautswouldn’tgetbored,stressed,orlonely,andlesstimeandspacewouldbeneededtohelpkeepthemfitorentertained.(為了去火星，宇航員每天需要大約30公斤的食物、水、空氣和其他補給。因此，冬眠可以大大減少它們的基本需求。此外，冬眠的宇航員不會感到無聊、壓力或孤獨，而且需要更少的時間和空間來幫助他們保持健康或娛樂。)”可知，冬眠的宇航員基本需求會顯著減少，也不會感到無聊、有壓力或孤獨，用于保持健康和娛樂的時間和空間也更少，說明他們的身體和心理需求都被降到了最低（Theirphysicalandmentalneedsarereducedtoaminimum）。故選D項。14．詞句猜測題。根據(jù)第四段中“Andthisiswhytheresearchonrats,notnaturallyhibernatinganimals,isinteresting.Researchonbearsisalsoimportantsincetheirbodysizeismorerelatabletoours.(這就是為什么對老鼠的研究很有趣，而不是自然冬眠的動物。對熊的研究也很重要，因為它們的體型與我們的體型更接近。)”可知，此處為我們?nèi)绾巫屇切┩ǔ２欢叩奈锓N進入冬眠狀態(tài)？故可猜測劃線單詞evoke為“喚起，引起”的意思，和A選項Initiate“發(fā)起，啟動”意思相近。故選A項。15．推理判斷題。根據(jù)最后一段中“Hibernationforhumansisanethicallycontroversialconcept,andcriticsmayconsideritasamadscientist’sdream.However,withoutsuchdreamers,humanitywouldstillbeintheMiddleAges.(人類冬眠在倫理上是一個有爭議的概念，批評者可能認為這是瘋狂科學家的夢想。然而，如果沒有這樣的夢想家，人類可能還停留在中世紀。)”可知，作者認為人類冬眠在倫理上有爭議，批評者可能認為這是瘋狂科學家的夢想，但如果沒有這樣的夢想家，人類可能還處于中世紀，說明作者認為人類冬眠可以推動社會進步（Itcanadvancesocialprogress）。故選C項。Passage5Spaceismostlyavastvacuum,yetthepartaroundEarthisahumaninfluencedenvironmentcrucialforsociety.Inrecentyears,wehaveexploredEarth’sincreasedvulnerabilitytospacialeventsandhowtheworldneedstorespond.Spacedangershavealwaysthreatenedthisplanet.Agiantasteroid(小行星)impactprobablykilledoffthedinosaurs,andasimilarstrikecouldsomedaydestroythehumanrace.ScientistshavestartedlaunchingspacebasedtelescopestotrackdangerousasteroidsandtestingmethodstosteerasteroidsawayfromEarth.Spaceweatherisanotherheadache.Bigsolarstormshappenaboutevery100years,andwe’reprobablyoverdueforone.Scientistscanpredictspaceweather,givingpeoplehours’orevenafewdays’warningtopreparefacilities.Butgovernmentshavetoknowhowtoactquicklywhentheygetsuchwarnings.Debrishatwe’veputintoorbitsurroundstheplanet,andthenumberofthingsupthereisrisingrapidly.Eventinypiecesofdebris,speedingasfastasbullets,candamagesatellitesthatprovidecriticalservicesonEarth’ssurfaceand,intheprocess,possiblycreateyetmoredebristhatthreatensotherobjectsinorbit.Humansarealsomakingtheskybrighterfrombelow,throughtheuseofincreasinglyintenseandwidespreadlighting,andfromabove,viasatellitesand,yes,allthatspacedebrisreflectingsunlightdowntoearth.Lightpollutioninterruptspeople’scircadianrhythms(晝夜節(jié)律)andharmstheirsleepandtheirmentalandphysicalhealth.Countriesthatareemployingspacealsoneedtopolluteless.Theyshouldworktogetheranddevelopunifiedstandardsforhowandwhenpeoplecanlaunchsatellites,rocketsandmoreintoorbit.Oneunderstandablereactiontoalltheseconcerns:Humanityhasahardenoughtimetakingcareofthelandenvironment;you’retellingmethere’sanotherone?Unfortunately,yes.Evenashumansstruggletopreservethegroundwewalkonortheairwebreathe,governmentsallovertheworldneedtotakecareofthezonefaraboveourheads,too.Acting,however,isoftenthehardestpart.16．Whatcanbeinferredfromthetextabouttheresponsetospacebasedthreats?A．Scientistshaven’tmentallypreparedforasteroidthreats.B．Authoritiescanreactquicklytospaceweatherwarnings.C．Lightpollutionisnotseriousenoughtorequireattention.D．Internationalactionislackinginsolvingspaceproblems.17．Whichofthefollowingisanimpactoflightpollution?A．Itcausesdamagetosatellitesinorbit.
