(课件网) Hubble ast astronaut Trouble with the Hubble 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 Hubble shuttle telescope Endeavour launch robot-arm space grab NASA atmosphere billion distant faulty galaxy astronaut universe eagle eye universe Are we alone(孤单的) in the universe in the universe=in space The Hubble telescope n.望远镜 v.缩短，压缩 tele- 远程，远距离的 television 电视 telephone 电话 telescope It is above the earth’s_____. atmosphere above=outside It costs over a billion dollars. over=more than It was launched into space by NASA． He is the director(局长) of NASA. astronaut The shuttle Endeavour will take the astronauts to the Hubble. endeavour ①v.奋力，努力 endeavour to do =try to do 竭尽全力做… ②n.尝试，努力 best endeavours 尽最大的努力 他总是竭尽全力帮助他人。 He always edeavours to help others. galaxy The galaxy is very _____from us. distant distant 遥远的，远方的;远亲的;冷淡的 the distant sound a distant cousin 一位远房（表）堂亲 distance n. 距离 in the distance 在远处 keep your distance 保持距离 grab v.抓，抓住，抓住（机会） grab sth from sb 从某人手里抢来某物 grab a chance 抓住机会 Grab your chance to travel while you`re still young at a cost of 造价为… at all costs 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。 She sent her daughter to America to study at all costs. pay/spend/cost/take ⑴pay 构成：sb pay +(money)+for sth pay for sth付…钱、pay for sb 替某人付钱 I paid 200 yuan for the new bike yesterday. ⑵spend 构成：sb spend +money +on sth sb spend +time +（in）doing sth ⑶cost （主语是物或it） 构成：sth + cost +（sb）+ money The book cost me 20 yuan. ⑷take 构成：it takes sb +time + to do It took me 5 hours to finish my homework. practise I _____ 3 hours doing the maths problem A new computer_____ a lot of money.
