哈勃、阿斯t、阿斯特罗诺姆、莱森61、troublewithout Hubble是以天文学家哈勃的名字围绕地球运行的望远镜。他的位置在地球的大气上，因此基础望远镜无法获得的好处图像不受大气湍流的干扰，可以观测到可能被臭氧层吸收的紫外线。这是自1990年发射以来天文史上最重要的契机。他已经填补了地面观测的空隙，帮助天文学家解决了很多根本问题，获得了更多的天文学物理学知识。1946年，从他最初的构想到发射，构建宇宙望远镜的计划不断受到延迟和预算问题的困扰。发射后，主警发现了球面像差，大大降低了望远镜的观测能力。幸运的是，在1993年的维修任务后，望远镜恢复了计划的质量，成为天文学研究和宣传的最重要的工具。哈勃空间望远镜，wordsandexpressions，hubbleshuttletelescopeendeavourlaunchrobot-armpacegrabnasatmosphereilliondistantfaultygalobot，universe，Arewealone(孤独)in the university？in the university=in space，whatcanweseeinspace？thehubbletelescope，n .望远镜v .缩短，压缩tele-remote，远距离television TV telephone电话，telescope，WhereistheHubble？itisabovetheearth s _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _。atmosphere、above=outside、guess : howmuchdoesitcost？itcossoverabilliondollars。over=more than，wholaunchedhehubbletelescopeintspace？itwalaunchedintspacebynasa、whois he？Heisthedirector of NASA，whatwilwedoifthehubbletelescopeisbroken？Whocanrepairit？astront、howcantheastronautsgettothehubble？theshuttleendavour willtethstronautstothehubble，endeavour， v .努力endeavourtodo=trytodo尽最大努力.尝试，尽最大努力。他总是尽力帮助别人。healwaysedeavourst tohelptothers，what is this？galaxy，thegalaxyisvery _ _ _ _ _ _ _ from us。distant、distant、远、远；远方亲戚冷冷的thedistantsoundadistantcousin远方(表格)离亲密的distance n . distance inthedistance远方keepyourdistance距离grabv。抓住，抓住(机会)，Grabsthfromsb从某人手中抢走某物grabyourchancetotraveleyou restillyoung，atatatcosts的费用.atallcosts不惜任何代价，她把女儿送到美国学习。shesendaughtertoamericatostudyatallcosts。cost，pay/spend/cost/take，配置pay:sb pay(money)forsthpayforsth支付.钱，payforsb付给某人IP ai d200 yuanforthenewbikeyesterday。spend配置：sb spend money onsthsbspendtime(in)doing sth，cost(主语或it)配置：sth cost(sb)moneytime配置take:ittakessb time today today tools kme 5 hourstofinish my homework，practose，_ _ _ _ _ _ _ the，troublesubetinttroubledtourettowublemakettable，摆脱困境解决问题，解决问题，v .失望，没错.不诚实disappointing令人失望bedisappointedinaperson/thing对某人或某事感到失望disappoint、sensendenndupsendmoutsender for、sensendenndupsendmoutsender for、submit、send、sendwhatwerethepicturesitsentuslike？3.whatwillthefournautsfromtheshuttleenderavourdoing？4.what will thepictursfromthehubbletellus？text、thehubbletelescopewalaunchedintspacebynasaonapril 20、1990 atatcosofoverabilliondollas、hundres、thousands，1 .rightfromthestart=fromtheverystart/beginning，2。thereisttroublewiththerewastroublewithsthecomputer。3 .faulty adj . faultn . afaultyanswer/afdefaultydecision，4 .disappointing adj，disappointed adj . shewasnointendatwhathenataid。Nasaisawnogoingtoputthetelescoperight、sotwitllsoonbesendingfoursitnautstorpairit、1。putsthright，have youputthewatchright？remembertoputthelights righttomorrow。2 .astrontn。=spaceman，Theshuttleendavour willpbetakingtheastroautstothehuble . a robot-armtheendeavour will grabthetelescopeandholditions，thehubblewiltellusagreatlabouttheageandsizeoftheuniversity . bythetimeyoureaddthis，Thehubbleseagleye will habsesentusthousagleye，a great deal批量/大量agreaeaterdealof.不可计数的名词bythetime语句至.blank filling :Thehubbletelescope _ _ _ _ _ _ _ _ _ intouspacebynasaonapril 20，1990NASA now _ _ _ _ _ _ _ _ _ _ _ putthetelescoperight，Sotwitllsoon _ _ _ _ _ _ _ _ _ _ _ _ _ the Hubble _ _ _ _ _ _ _ abovetheearth at mosphere，Sotwitllsoon _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ the Hubble _ _ _ _ _ _ _ _ usagreatelabouttheageandsizeoftheuniversity。bythetimeyou _ _ _ _ _ _ _ _ this，the Hubble seagle eye _ _ _ _ _ _ _ _ _ _ _ _
