选必3Unit2Reading:Life on a space stationLiving in space isevery would-be astronautsdream.My six-month stayona space stationhas cometo an end,and ithas beena challengingbut magicaladventure.I betyoud loveto knowwhat dailylifeis likeup in space andhow itdiffers fromthat on the Earth——the low gravity definitelymakesordinary thingsstrange!准宇航员的梦想
1.would-be astronautsdream充满挑战但神奇的冒险
2.a challengingbut magicaladventure.The strangenessof livingin space is apparentfrom themoment wesleep.Due to the nearabsence ofgravity in space,we haveto attachourselves so that wedont float around.We usuallysleep inprivatequarters,which aremore likelarge cupboards,or insleeping bagsattached tothe wallsor theceiling.Its strangethat wetry tosleep withno pressureagainst ourback,but theunusual bedsdontbother usany more.After abouteight hoursof sleep,we startour dayof work.
3.strangeness^unusualness明显不同于
4.be apparentfrom由于太空
5.Due tothe nearabsence ofgravityin space,we haveto attachourselves sothat wedont floataround.中几乎没有重力，我们必须附着自己，这样我们就不会漂浮The routinetasks thatoccupy mostof theday aredemanding,but theycan alsobe extremelyrewarding.Our mainmission is to conductscientific research.We need to evaluatethe effectsof lowgravityon animalsand plants.Creatures such as micefish andmosquitoes havealso beensent tothestation!In alow-gravity environmentwe canlearn moreabout changesin cellsand microorganismszunderthe microscope.As wellas doingthese biologicalexperiments,we carry out experimentsinother researchfields.I havebeen workingon oneexperiment whichlocates andtracks lightningoverlarge regionsof the Earth.Hopefully,it willcast newlight on the Earthsclimate andlead to betterlightning protection.With somuch goingon the space stationneeds alot ofmaintenance,so weconstantlycheck supportsystems anddo somecleaning.占据一
6.The routinetasks thatoccupy mostof theday aredemanding,but theycan alsobe extremelyrewarding.天中大部分时间的例行任务要求很高，但它们也可能非常有益
7.evaluate-assess-estimate投下新的光芒
8.cast newlight on更好的防雷保护
9.better lightningprotection
10.maintenance-mending-fixtureThe mostchallenging worktakes placewhen weneedtoperform tasksoutside the space stationsuchas testingnew equipment,monitoring scientificexperiments orrepairing the spacestation.In thecircumstances,its timefor aspacewalk.First,we puton ourspacesuits,which allowus tobreathe inspaceand protectus fromexposure tothe coldand radiation.Then wehead out,and sometimesperformtasks forhours ata time,with thebeautiful Earthvisible below.Splendid asthe view of theEarth is,spacewalking isnot asexciting asyou mightthink.Its probablythe mostdangerous work,with potentialrisks such as electricshocks.Thats whyevery spacewalkis carefullyplanned.尽管地球的景色很灿烂，
11.Splendid asthe viewof the Earth is,spacewalking isnot asexciting asyou mightthink.但太空行走并不像你想象的那么令人兴奋潜在风险
12.potential risksInviewof the low-gravity environment,eating isalso differentinspace.Most foodis driedorfreeze-dried.Its aluxury toeat freshfood,because freshproduce such as fruitand vegetablescanonly bedelivered tothe spacestation from the Earthevery coupleof months.Salt andpepper areonlyin liquidform,sothat they willnot floataway andblock theair pipes.However,liquids cantbeeasily controlledinspace.We mustdrink wateror anyother liquidsout ofa bagthrough athin tubeofplastic.Furthermore,to keepour bodyhealthy,we mustensure abalanced supplyof nutrientsbytaking pills.冻干的
13.freeze-dried奢侈品
14.a luxurySpendingsometime in the gymis ofvital importanceto astronautshealth.Did youknow thatin justfivemonths,astronauts couldlose asignificant amountof muscleand bonemass Consideringthesenegative effectslowgravityhas on the humanbody wediscipline ourselvesto doat leasttwo hoursofexercise everyday.Exercise inspaceisnot youraverage workout.We haveto betied ontospeciallydesigned exerciseequipment tostop ourselvesfrom floatingaround.至关重要
15.be ofvital importance大量肌肉和骨量流失
16.lose asignificant amountof muscleand bonemass自律
17.discipline ourselvesDuringour leisuretime,theres nothingwe likemore thanto sitback withthe restof thecrew andwatchour remarkableplanet goby,taking picturesfor ourfamily andfriends backhome.As thespacestation travelsataspeed ofabout17,500miles perhour,we getto seethe sunriseevery90minutes.In theseprecious moments,all thechallenges oflife inspace seemworth it.珍贵的时刻
18.precious momentsGrammarUsageFor thousandsof years,people havelooked tothe starrysky and wondered what,or who,is outthere.In theearly1600s,Galileo wasthe firstto usehis telescopeto explorethe skyand sincethen,telescopes havecontinually improved.星空
19.the starryskyOne majorbreakthrough camein1990,when theHubble Space Telescope waslaunched.That Hubbleisbased inspace allowsit tosee furtherthan ground-based telescopes,and itallows scientiststolearn moreabout the universe.Hubble observationshave playeda crucialrole inthe discoveryof themysteriousdark energj.Hubble wasfollowed bythe KeplerSpaceTelescopein

20.have playeda crucialrole神秘的暗能量
21.the mysteriousdark energy
22.Whether lifeon otherplanets doesexistisyettobeproved,but thesigns arepromising:Kepler hasdetected其他行星上的生命是否确实存在还有待证实，但manysuitableplanets thatare almostthe samesize asthe Earth.迹象是有希望的开普勒已经探测到许多合适的行星，它们的大小几乎与地球相同In recentyears Chinahas developedadvanced telescopesas well.One exampleis theinnovative FASTwhichis thelargest single-dish radiotelescope inthe world.With adish thesize of30football fields,FAST isable tocarryoutobservations with extraordinary sensitivity.One ofits scientificgoals istodetect communicationsignals betweenthe starsinthe universe.,具有非凡的敏感性
23.withextraordinarysensitivityIt isclear thattelescopes arecrucial toolsfor space exploration and that developingthe requiredtechnologywill helpastronomers allover theworld makeexciting discoveries.How muchwe willlearn fromthe telescopes is merely limited by our imagination.,我们能从望远镜中学到多少
24.How muchwe willlearnfromthetelescopesismerelylimitedbyourimagination东西，只是受到我们的想象力的限制Extended Reading:Why weexploreIn1969,when NeilArmstrong firstlanded on the Moon,many peoplethought thatsoon wewould beregularlyvisiting otherplanets in our solar system andwould evendare totravel beyondit.This isclearlynot thecase.The realityis thatspace exploration is extremelydifficult anddangerous,cantake avery longtime andcosts ahuge amountof money.Some peoplebelieve thatwhile spaceexploration expands our understanding of the universe,it isa wasteof the public purse and doesnothingto enhancethe qualityof ourlives hereontheEarth.Why dowe continue to explore space,then
25.Some peoplebelieve thatwhile spaceexplorationexpandsourunderstanding of the universe,it isa wasteof.有些人认为,虽然太空探索thepublicpurseanddoes nothingto enhancethe qualityof ourlives hereontheEarth扩大了我们对宇宙的理解，但它浪费了公共资金，对提高我们在地球上的生活质量没有任何帮助It isinournature to explore.From thevery earlydays ofhuman lifeontheEarth,our curiosityaboutthe unknownhas keptus adventuringinto newplaces.We longto visitthick andwild forests,climbvast mountain ranges,and crossdeep oceans.We desiretoexplorethe furthestfrontier ofall-space.As StephenHawking oncesaid/Remember tolook upat thestars andnot downat yourfeet.Try tomake sense of what you see andwonder about what makes theuniverse exist.Be curious.That wearefascinated bythe skyis evidentin ancienttales fromaround theworld,suchasthat ofChange.While spaceexplorationisa reality,we remaincurious about the mysteriesoftheuniverse.Witheach spacemission comesgreater insight,thus motivatingus tocontinue alongthe samepath ofadventure..我们渴望去茂密的
