The moon may hold frozen water in more places and in larger quantities than previously suspected.And for the first time,the presence of water on the moon’s sunlit surface has been confirmed,scientists reported.That’s good news for astronauts at future lunar bases who could tap into these resources for drinking and making rocket fuel.
More than 40,000 square kilometers of lunar surface have the capability to trap water in the form of ice,according to a team led by the University of Colorado’s Paul Hayne.That’s 20% more area than previous estimates,he said.These latest findings expand the possible landing spots for robots and astronauts.
The presence of water in sunlit surfaces had been previously suggested,but not confirmed.The molecules(分子) are so far apart that they are in neither liquid nor solid form,said lead researcher Casey Honniball of NASA’s Goddard Space Flight Center.And NASA’s astrophysics director Paul Hertz said it’s too soon to know whether this water—found in and around the southern hemisphere’s sunlit Clavius Crater—would be accessible.
As for the shadowed areas believed to be rich in frozen water near the moon’s north and south poles,temperatures are so low that they could hold onto the water for millions or even billions of years.These so-called cold traps get down to minus 163 degrees Celsius.
Using data from NASA,the researchers identified the size of cold traps and used computer models to get all the way down to micrometers in size.“Since the little ones are too small to see from orbit,despite being vastly more numerous,we can’t yet identify ice inside them,” Hayne said,“Once we’re on the surface,we will do that experiment.”
Scientists believe all this water on the moon came from comets,asteroids(小行星),interplanetary dust,the solar wind or even lunar volcanic eruptions.They’ll have a better idea of the sources “if we can get down on the surface and analyze samples of the ice,” Hayne said.
4.What can be inferred from the text
A.Water is extremely crucial for space exploration.
B.Researchers identified cold traps using computers.
C.Scientists knew well the sources of water on the moon.
D.Cold traps are found in and around the southern hemisphere.
5.What do we know from paragraphs 3 and 4
A.The presence of water hasn’t been confirmed.
B.Shadowed areas are abundant in frozen water.
C.Water can be easy to obtain on the moon soon.
D.Water molecules on the moon are closely connected.
6.What does the underlined word “them” in paragraph 5 refer to
A.Data.
B.Sunlit surfaces.
C.Cold traps.
D.Computer models.
7.What is the main idea of the text
A.The sources of water on the moon.
B.Water ice is widespread on the moon.
C.Good news for astronauts at lunar bases.
D.Moon holds more water than ever thought.

Ⅱ.七选五
(2025·湖南衡阳模拟)
Over the last 60 years,many spacecraft have flown by,orbited and even landed on Mars.But human explorers could work faster and be more flexible than machines.Setting foot on Mars would be a major milestone in space exploration.　8　 However,it is difficult to survive this adventure.
First,a roundtrip to Mars causes many extra health risks.For one thing,floating in microgravity for long periods weakens bones and muscles.For another,it allows fluid to build up in the head.　9　 Luckily,artificial gravity machines could help.
Then there’s space radiation to worry about.The Earth’s magnetic field protects astronauts near Earth from high-energy cosmic(宇宙的) rays.Those cosmic rays might raise the risk of cancer and other health problems.　10　 This increases the risk of developing the diseases.Taking certain vitamins could reduce the impacts.
　11　 Since astronauts can’t carry construction materials from Earth,scientists are dreaming up ways for astronauts to use materials on Mars.Long-term visitors would also need plenty of oxygen to breathe.A device on NASA’s Perseverance rover is currently laying the groundwork for a future Mars oxygen factory.
Planning a trip to Mars isn’t just about keeping astronauts safe.　12　 Humans are filled with microbes(微生物).And spreading those microbes could be bad for the search for life on Mars.As a result,a key part of responsible space exploration is making sure Earth bacteria don’t infect other planets.
A.Exploring space always comes with risks.
B.It also involves protecting Mars from astronauts.
C.They can’t restock like astronauts on the space station do.
D.On longer journeys astronauts would face prolonged exposure.
E.That’s why certain nations are interested in dispatching humans to Mars.
F.This can lead to increased pressure in the eyes and result in vision complications(并发症).
G.Establishing and surviving in a Mars colony would present numerous challenges.

2.C　细节理解题。根据Camp Information部分中的“Fees:$700.A 30% non-refundable prepayment will be collected at the time of booking your Camp KSC International reservation.”可知,如果一名学生退出夏令营,最多能获得700×(1-30%)=490美元退款,故选C项。
3.C　细节理解题。根据倒数第二段“Each participant must be able to read,understand,and follow English directions.”可知,参加营地活动需要具备基本的英语口语能力,故选C项。
【语境猜词】
①微重力　②给……编程　③动手的;亲身实践的　④不可退款的
【语篇解读】本文是一篇说明文。文章介绍了科学家报告月球存水情况超预期,首次证实月球日照面有水,这不仅拓展了登月着陆点的选择,也为建立可持续月球基地提供了关键资源。
4.A　推理判断题。根据第一段中的“That’s good news for astronauts at future lunar bases who could tap into these resources for drinking and making rocket fuel.”可知,航天员可以利用水资源来饮用和制造火箭燃料,所以水对于太空探索极为重要,故选A项。
5.B　细节理解题。根据第四段中的“As for the shadowed areas believed to be rich in frozen water near the moon’s north and south poles”可知,月球的阴影区域富含冰冻水,故选B项。
6.C　代词指代题。根据第五段中的“Using data...‘Since the little ones are too small to see from orbit,despite being vastly more numerous,we can’t yet identify ice inside them,’”可知,“them”指代上文提到的“cold traps(冷阱)”,即现在还无法识别冷阱内部的冰,故选C项。
7.D　主旨大意题。文章开篇点明“The moon may hold frozen water in more places and in larger quantities than previously suspected.”,即月球上可能有更多的地方存在冰冻水,其储量也可能比以往认为的更丰富。接着围绕这一观点展开,介绍了月球日照面水的证实情况、阴影区域存水情况、冷阱研究以及水的可能来源等内容。所以文章核心强调的是月球上的水比以往认为的更多,故选D项。
【语境猜词】
①先前地;以前地　②留住(气体、水或能量)　③天体物理学
④半球　⑤微米级(单位)
Ⅱ.【语篇解读】本文是一篇说明文,文章介绍了人类探索火星所面临的挑战和困难。文章从多个角度分析了人类登陆火星的可能性和难点,包括健康风险、空间辐射、生存条件的建立以及保护火星环境等方面。
8.E　根据上文“But human explorers could work faster and be more flexible...Setting foot on Mars would be a major milestone in space exploration.”可知,探索火星对人类而言意义重大,E项“这就是某些国家有兴趣将人类送往火星的原因。”能承接上文,是对上文的总结。
9.F　根据上文“For another,it allows fluid to build up in the head.”可知,长时间在微重力环境下会导致头部积液,本空应继续解释这种现象导致的健康后果,F项“这可能会导致眼睛压力增加,并导致视力并发症。”说明了头部积液可能导致的视力问题,能承接上文。
10.D　根据上文“Those cosmic rays might raise the risk of cancer and other health problems.”可知,这里提到宇宙射线会增加健康风险,D项“在长途太空旅行中,航天员将面临长时间的暴露风险。”承接上文,继续谈论这种暴露对于航天员的影响。
11.G　设空处位于段首,是本段主题句,根据下文内容可知,下文具体解释了人类在火星生存将面临的具体挑战,包括建筑材料的获取和氧气需求量大。G项“在火星定居地建立和生存将面临诸多挑战。”概括了本段内容,能引出下文。
12.B　根据下文内容可知,人类体内充满了微生物。传播这些微生物可能会对寻找火星上的生命造成不利影响。B项“它还涉及保护火星免受航天员的伤害。”说明了除了保护航天员外,还需要保护火星不受航天员的影响。
【语境猜词】
①里程碑　②患(病)　③基础工作;准备工作　④使受影响
Ⅲ.【语篇解读】本文是一篇说明文。文章介绍了人类探索外太空的梦想以及科学家为实现这一梦想所做的努力和取得的成就。
13.which　考查定语从句。设空处引导非限制性定语从句,从句中缺少主语,先行词是their dream,指物,故填which。
14.to be sent　考查不定式和被动语态。person前有序数词the first修饰,空格处用不定式作后置定语,人是被送入太空,故填to be sent。
15.saying　考查非谓语动词。set是谓语,设空处用非谓语动词,Neil Armstrong和say之间是逻辑上的主谓关系,因此用动词-ing形式作状语,故填saying。
16.Despite　考查介词。根据语境可知,句子前后语义存在转折关系,所填词与“the great achievements”构成介词短语,意为“尽管”,且设空处位于句首,故填Despite。
17.However/Nevertheless　考查副词。根据上下文语境可知,此处表转折,意为“然而”,有逗号隔开,且设空处位于句首,故填However/Nevertheless。
pared　考查非谓语动词。started是谓语,设空处用非谓语动词,China和compare之间是逻辑上的动宾关系,因此用过去分词作状语,句首首字母大写,故填Compared。
19.have been　考查时态和主谓一致。根据So far可知,句子时态是现在完成时。主语several astronauts是复数形式,故填have been。
20.making　考查非谓语动词。谓语是has...launched,设空处用非谓语动词,前面描述的事情和mark之间是逻辑上的主谓关系,因此用动词-ing形式作状语,故填marking。
21.a　考查冠词。station是可数名词单数形式,表泛指,设空处用不定冠词,且space发音以辅音音素开头,故填a。
22.is believed　考查固定句型和时态。句子描述客观事实,时态用一般现在时,It is believed that...是固定句型,意为“人们相信”,故填is believed。
【语境猜词】
①摆脱(地球引力)　②环绕……的轨道运行　③探索
