HubbleastastronautTroublewiththeHubble•是以天文学家哈勃为名，在轨道上环绕著地球的望远镜。他的位置在地球的大气层之上，因此获得了地基望远镜所没有的好处——影像不会受到大气湍流的扰动，还能观测会被臭氧层吸收的紫外线。于1990年发射之后，已经成为天文史上最重要的仪器。他已经填补了地面观测的缺口，帮助天文学家解决了许多根本上的问题，对天文物理有更多的认识。•从他于1946年的原始构想开始，直到发射为止，建造太空望远镜的计划不断的被延迟和受到预算问题的困扰。在他发射之后，立即发现主镜有球面像差，严重的降低了望远镜的观测能力。幸好在1993年的维修任务之后，望远镜恢复了计划中的品质，并且成为天文学研究和推展公共关系最重要的工具。哈勃太空望远镜HubbleshuttletelescopeEndeavourlaunchrobot-armspacegrabNASAatmospherebilliondistantfaultygalaxyastronautuniverseeagleeyeuniverseArewealone(孤单的)intheuniverse?intheuniverse=inspaceTheHubbletelescopen.望远镜v.缩短，压缩tele-远程，远距离的television电视telephone电话telescopeItisabovetheearth’s___________.atmosphereabove=outsideItcostsoverabilliondollars.over=morethanItwaslaunchedintospacebyNASA．Heisthedirector(局长)ofNASA.astronautTheshuttleEndeavourwilltaketheastronautstotheHubble.endeavour①v.奋力，努力endeavourtodo=trytodo竭尽全力做…②n.尝试，努力bestendeavours尽最大的努力他总是竭尽全力帮助他人。Healwaysedeavourstohelpothers.galaxyThegalaxyisvery_______fromus.distantdistant遥远的，远方的;远亲的;冷淡的thedistantsoundadistantcousin一位远房（表）堂亲distancen.距离•inthedistance在远处•keepyourdistance保持距离grabv.抓，抓住，抓住（机会）☆grabsthfromsb从某人手里抢来某物☆grabachance抓住机会Grabyourchancetotravelwhileyou`restillyoung•atacostof造价为…•atallcosts无论如何，不惜任何代价她不惜任何代价都要送他的女儿去美国读书。ShesentherdaughtertoAmericatostudyatallcosts.pay/spend/cost/take⑴pay构成：sbpay+(money)+forsthpayforsth付…钱、payforsb替某人付钱Ipaid200yuanforthenewbikeyesterday.⑵spend构成：sbspend+money+onsthsbspend+time+（in）doingsth⑶cost（主语是物或it）构成：sth+cost+（sb）+moneyThebookcostme20yuan.⑷take构成：ittakessb+time+todoIttookme5hourstofinishmyhomework.practise•I______3hoursdoingthemathsproblem•Anewcomputer______alotofmoney.•Repairingthisnewcar______thewholeafternoon.•It______me4yearstofinishthebook.•Ihaveto____them20yuanforthisskirt.askfortroublegetintotroublegetoutoftroublemaketrouble自讨苦吃陷入困境脱离不幸（困境）闹事，捣乱v.使失望，对…失信disappointing令人失望的disappointed失望的bedisappointedinaperson/thing对某人或某事失望sendinsendupsendoutsendfor递交，送来发射，发出派遣派人去叫1.WhenwastheHubbletelescopelaunchedintospace?2.Whatwerethepicturesitsentuslike?3.WhatwillthefourastronautsfromtheshuttleEndeavourdoing?4.WhatwillthepicturesfromtheHubbletellus?TextTheHubbletelescopewaslaunchedintospacebyNASAonApril20,1990atacostofoverabilliondollars.hundreds,thousands,millions,billions+ofRightfromthestarttherewastroublewiththeHubble.Thepicturesitsentuswereverydisappointingbecauseitsmainmirrorwasfaulty!1.rightfromthestart=fromtheverystart/beginning2.ThereistroublewithsthTherewastroublewiththecomputer.3.faultyadj.faultn.afaultyanswer/afaultydecision4.disappointingadj.disappointedadj.Shewasdisappointedatwhathesaid.NASAisnowgoingtoputthetelescoperight,soitwillsoonbesendingupfourastronautstorepairit.1.putsthrightHaveyouputthewatchright?Remembertoputthelightsrighttomorrow.2.astronautn.=spacemanTheshuttleEndeavourwillbetakingtheastronautstotheHubble.Arobot-armfromtheEndeavourwillgrabthetelescopeandholditwhiletheastronautsmakethenecessaryrepairs.Ofcourse,theHubbleisabovetheearth'satmosphere,soitwillsoonbesendingustheclearestpicturesofthestarsanddistantgalaxiesthatwehaveeverseen.TheHubblewilltellusagreatdealabouttheageandsizeoftheuniverse.Bythetimeyoureadthis,theHubble'seagleeyewillhavesentusthousandsandthousandsofwonderfulpictures.agreatdeal大量/许多agreatdealof…+不可数名词bythetime+句子：截止到……TheHubbletelescope_________intospacebyNASAonApril20,1990,atacostofoverabilliondollars.Rightfromthestartthere_____troublewiththeHubble.Thepicturesit_____us_____verydisappointingbecauseitsmainmirror______faulty!NASAnow______________putthetelescoperight,soitwillsoon_________fourastronautstorepairit.TheshuttleEndeavour____________theastronautstotheHubble.Arobot-armfromtheEndeavour________thetelescopeand_______itwhiletheastronauts______thenecessaryrepairs.Ofcourse,theHubble________abovetheearth’atmosphere,soitwillsoon__________ustheclearestpicturesofstarsanddistantgalaxiesthatwehaveever_________.TheHubble_______usagreatdealabouttheageandsizeoftheuniverse.Bythetimeyou________this,theHubble’seagleeye___________usthousandsandthousandsofwonderfulpictures.waslaunchedwassentwerewasisgoingtoputbesendingupwillbetakinggrabholdmakeisbesendingseenwilltellreadwillhavesent在现在时间的句子里,可用现在时表示将来.这里的现在时是一个广义的时间,它在实际上包括现在完成时,它们的道理是相通的.Whenhehasfinishedthisproject(工程),IwillarrivedinUKforanotherproject.当他完成这项工程的时候，我就会到英国去商议另一项工程．Ifhehasstartedonhiswayhere,Iwillwaitanotherhour.如果他已经起程来这里了，我就再等一个小时．
