nautsreturningtoEarthistravelingthroughtheatmosphere.Afterthere-entrycapsuleenterstheatmosphere,thereisfiercefrictionwiththeair.(宇航员返回地球的另一个挑战是穿越大气层。返回舱进入大气层后，与空气摩擦激烈)”可知，上文提到返回舱与空气摩擦激烈，故本句是在说明其结果：太空舱表面温度可达数千度。故E选项“太空舱表面温度可达数千度”符合语境，故选E项。牝10、根据上文“There-entrycapsulelandeduprightintherightarea.SuchalandingpositionisrareinChina’sspaceflighthistory.(返回舱着陆直立在正确的区域。这样的着陆位置在中国航天飞行史上是罕见的)”可知，本句主要是关于中国航天飞行史上返回舱直立着陆的说明，故G选项“到目前为止，只有神舟六号和神舟十三号实现了垂直着陆”符合语境，故选G项。11、B牝12、C牝13、G牝14、F牝15、D【分析】本文是一篇说明文。这篇文章就人们为什么去旅游给出了几个原因。牝11、根据上文Sometimesyoufindyourselfinthemiddleofnowhere.可知有时你会发现自己没有存在感．B项：Travellingletsyoudiscoveryourself旅行会让你发现自己。符合文意，故选B项。牝12、空格处是段落标题。根据下文Ifyoulookbackatalltheamazingmemoriesofyourlife,youwillrealizethatmostofthemwereoutofyourcomfortzone.Travellingisdangerous,fulloflifethreateningpossibilitiesandwillnotalwaysbecomfortable可知，如果你回顾你生命中所有令人惊异的记忆，你会意识到它们中的大多数都不在你的舒适区，旅行是危险的，充满了威胁生命的可能性，不会总是舒适的，故C项“这一自然段描述了旅游打破了你的舒适带”符合文意，所以选C。牝13、根据上文Moneyisworthnothingifyoucannotspenditonalittleadventure.可知，如果你不能把钱花在一次小小的冒险上，钱就一文不值。因此推断G项：Escapelifeforalittlewhilebecauseexperienceisfarmorevaluablethanmoney．逃避生活一段时间，因为经历远比金钱更有价值。符合文意，故选G项。牝14、根据上文Thefeelingofbeingawayfromyourworkplaceispurehappiness.Thefeelingofnothavingtoworryabouttheneverendingpilesoffilesispurejoy.可知离开工作场所的感觉是纯粹的幸福，不用担心那些没完没了的文件的感觉是纯粹的快乐。F项：Andthefeelingofbeingawayfromyourbossforafewdaysispurepleasure．离开老板几天的感觉纯粹就是一种享受，符合文意，故选F项。牝15、根据上文Lifeisshortandtheworldiswide.Onedayyoumightwakeupandrealizethatyoudon’thavetimetodoeverythingthatyouhavealwayswantedtodo,anymore.Onceinawhile,maketimetoappreciatethefactthatyouarealive,young,freeandhealthy.可知生命短暂，世界广阔。总有一天，你可能会醒来，意识到你没有时间去做你一直想做的一切，再也不会了。偶尔，花点时间欣赏你还活着，年轻，自由和健康的事实。因此推断这里意思是去旅游来庆祝生活本身。故选D项。16、F牝17、C牝18、A牝19、E牝20、G【分析】这是一篇说明文。文章介绍了人们喜欢冒险的来源和科学依据，人们都喜欢冒险，因为风险也意味着回报，生活中人们喜欢做一些让别人意外和害怕的事，这和人的大脑有关．牝16、根据前文becausewhenweweightheriskandthereward,theriskseemsworthtasking.当我们衡量风险和回报时，风险值得去冒。根据后文Someofusenjoyactivitiesthatwouldsurpriseandscaretherestofus.有些人喜欢做一些让别人意外和害怕的事。也就是说衡量风险的标准每个人都可能不一样．故F选项“然而，我们并不是都使用相同的参考标准来衡量风险和回报”与上文为转折关系，且承接下文。故选F项。牝17、根据前文Risk-takerswerebetterathunting，fighting，orexploring．喜欢冒险的人表现更优秀，这意味着他们有更大的机会生存下去。故C选项“这意味着他们有更大的机会生存下去”承接上文。故选C项。牝18、根据前文Somaybeyoulovecarracing，ormaybeyouhateit．也许你喜欢赛车，也许你不喜欢，这要依据你的性格。故A选项“这要依据你的性格”承接上文。故选A项。牝19、根据前文scientistssaythatyourWillingnesstotakerisksincreasesduringyourteenageyears.科学家们指出冒险的意愿在年轻时会不断强烈。根据下文Tohelpyoudothat,yourbrainincreasesyourhungerfornewexperiences.为了帮你实现那些，大脑会不断增加你对新的经历的渴望。而这些是在你离开家庭，走进一个更大的世界的时候。故E选项“这些是在你离开家庭，走进一个更大的世界的时候”承接上下文。故选E项。牝20、根据下文Fortherisk-seekersapartofthebrainrelatedtopleasurebecomesactive,whilefortherestofus,apartofthebrainrelatedtofearbecomesactive.不同的人的大脑在处理快乐和恐惧时表现也会不一样。故前面应该是说大脑的不同反应。故G选项“新的大脑研究表明，当我们面对紧张的情况时，我们的大脑会以不同的方式工作”承接下文。故选G项。21、F牝22、D牝23、B牝24、E牝25、G【导语】这是一篇说明文。本文阐述了为了解决由碳排放造成的极端天气，许多科技公司捕获和再利用二氧化碳。牝21、根据上一句“Theworldhasexperiencedalotofextremeweatherthisyearduetoclimatechange,whichcarbonemissionsarebelievedtobemostresponsiblefor.(由于气候变化，世界今年经历了很多极端天气，碳排放被认为是最主要的原因)”可知，碳排放成为极端天气的原因，推知该空会提到怎样解决这个问题，因此F选项“Tosolvetheproblem,capturingandreusingCO2isanoptionfortechcompanies.(为了解决这个问题，捕获和再利用二氧化碳是科技公司的一个选择)”切题，该选项承接上文，且选项中的“problem”对应上文中的“extremeweather”。故选F项。牝22、根据上文“Meatmadefromair…Tocreatetheprotein,thecompanyusesrenewableenergytosplitwatercellsintohydrogenandoxygen(用空气制成的肉……为了制造这种蛋白质，该公司使用可再生能源将水细胞分解成氢和氧)”和下文“Thisisfedtomicrobes,whichinturncreateaneatablefood(这是微生物的食物)”可知，本段主要阐述由二氧化碳怎样制作微生物的食物，因此，D选项“ThenitmixesthehydrogenwithCO2andaddsothe
