　　篇章剖析: 这篇文章讲述了美国重新规划的太空四个项目。第一段讲述乔治布什重新规划了美国太空机构的任务;第二、三段是第一个项目无线电天文望远镜计划;第四、五段分别讲述了其余三个项目;第六段讲述了宇航局对这些项目的看法。词汇注释： morsel n. 少量 din n. 度，定(德国工业标准感光片感光度单位 ) astrophysicist n. 天体物理学家 extraterrestrial adj. 地球外的 tenuous adj. 稀薄的 geodesy n. 测地学 sprinkle v. 喷洒难句突破： So when George Bush redirected Americas space agency, NASA, away from scientific research and towards a manned return to the moon in 2004, many scientists were disappointed. So when George Bush redirected away from and towards , many scientists were 这是一个复合句，前面when引导的是时间状语从句。因此，乔治布什重新规划了美国太空机构国际航空和宇宙航行局的任务，从科学研究转为2004年有人驾驶飞船返回月球，许多科学家都感到失望。 A second project, headed by Michael Collier, of the NASA Goddard Space Flight Centre, would examine how the solar wind a stream of charged particles ejected from the sun interacts with the tenuous lunar atmosphere close to the moons surface. A second project would examine 这是一个复合句，how引导的是宾语从句;headed 分词结构修饰前面的project. 第二个项目是美国国家宇航局戈达德太空飞行中心的Michael Collier主持的，要检查太阳风(太阳喷射出的一个粒子流)和微薄的月球大气层如何互相作用。题目分析： 1.George Bush redirected NASA away from scientific research because_____ 1.乔治布什让美国宇航局转离研究是因为_____ he thought scientific research is useless in the long term. 他认为科学研究从长远来看是没用的。 he thought launching people into space was not the first priority. 他认为将人类送往太空不是第一要务。 he thought NASA should manage its own business. 他认为宇航局应该管好自己的事情。 he thought research was not so practical. 他认为研究不是那么实用。 D ☆☆☆☆ 推理题。根据第一段，将人类送往太空没有多少用处，因此，乔治布什重新规划了宇航局的任务。选项中D最为符合题意。 2.Which one of the following statements is TURE of the radio telescope? 2.关于无线电望远镜，下列哪个陈述是正确的? The radio telescope could look back at the structures of galaxies and stars when they were firstly formed. 无线电望远镜可以回溯看到银河系和行星形成时的结构。 The device would be interfering with shorter-wavelength radio waves used for communication on Earth. 该装置会干扰地球上用于通讯的短波无线电波。 The device could protect long wavelength from being absorbed by the outermost layers of the planet s atmosphere. 该装置可以保护长波不会被星球最外面的大气层吸收。 The device could have unique functions mainly because of the position it would be adjusted. 该装置有特殊的功能，主要是因为它未来要调节到的位置。 D ☆☆☆ 细节题。根据第二段，A选项，是回溯看到星体形成时的宇宙的情况，而不是它们的结构;B选项，没有提到是否干扰;C选项，并不是保护，而是因为它所处的位置可以探测到没有被大气层吸收的波长;D选项，提到了望远镜安装到离无线电波很远的地方，这样才可以看到早期宇宙的情况。因此，答案为D选项。 3.The radio telescope might also be useful in searching for extraterrestrial beings in that_____ 3.无线电望远镜也可以用于搜索外星生物，因为_____ it could let the astrophysicists examine all the planets in unprecedented detail. 它可以使得天体物理学家非常精细地视察所有的行星。 it could find out the magnetic field which could protect beings from being attacked by space particles. 它可以发现保护生物不受太空颗粒的碰撞攻击的磁场。 it could detect any star and exoplanet surrounding the Earth. 它可以探测到地球周围任何的行星和外行星。 it could search out the promising sign for finding extraterrestrial life. 它可以发现寻找外星生物的迹象。
