 Passage 2
        Astronaut Jim Voss has enjoyed many memorable moments in his career, including three space flights and one space space walk. But be recalls with special fondn ess a decidedly earthbound(为地球引力所束缚的) experience in the summer of 1980 when he participated in the NASAASEE Summer Faculty Fellowship Program. Voss, then a science teacher at West Point, was assigned to the Marshall Space Flight Center's propulsion lab in Alabama to analyze why a hydraulic fuel pump seal on the space shuttle was working so well when previous seals had failed. It was a s eemingly tiny problem among the vast complexities of running the space program. Yet it was important to NASA because any crack in the seal could have led to des tructive results for the astronauts who relied on them.
        
        “I worked a bit with NASA engineers,” says Voss, “but I did it mostly by an alysis. I used a handheld calculator, not a computer, to do a thermodynamic(热力 学的) analysis.” At the end of the summer, he, like the other NASAASEE fellow s working at Marshall, summarized his findings in a formal presentation and deta iled paper. It was a valuable moment for Voss because the ASEE program gave him added understanding of NASA, deepened his desire to fly in space, and intensifie d his application for astronaut status.
        
        It was not an easy process. Voss was actually passed over when he first applie d for the astronaut program in 1978. Over the next nine years he reapplied repea tedly, and was finally accepted in 1987. Since then he has participated in three space missions. The 50yearold Army officer, who lives in Houston, is now in training for a fourmonth mission as a crew member on the International Space Station starting in July 2000.
        
        Voss says the ASEE program is wonderful for all involved. “It brings in peopl e from the academic world and gives NASA a special property for a particular per iod of time. It brings some fresh eyes and fresh ideas to NASA, and establishes a link with our colleges and universities,” Voss explains. “There's an exchang e of information and an exchange of perspectives that is very important.”
        
        For the academic side, Voss says, the ASEE program also “brings institutions of higher learning more insight into new technology. We give them an opportunity to work on realworld problems and take it back to the classroom.”
        
        36. Why was the hydraulic fuel pump seal important for the space shuttle?
        A) Because previous seals all failed.
        B) Because it was very complex in running the space program.
        C) Because great care has to be taken of the hydraulic fuel pump sealing.
        D) Because any crack in the seals would cause disastrous results for the astro nauts.
        
        37.The great significance of Voss's findings lies in .
        A) strengthening his determination to join in space flights
        B) furthering his understanding of NASA
        C) consolidating his astronaut status in NASA programs
        D) Both A and B
        
        38. How many flights will Voss have finished if his fourmonth mission s tarting in July 2000 ends up successfully?
        A) Three.
        B) Two.
        C) Four.
        D) Five.
        
        39. Which of the following is NOT TRUE according to what Voss said on the ASEE program?
        A) Fresh members from the academic world participate in the program.
        B) The program brings new outlooks to NASA space programs.
        C) It is important for the space scientists to exchange information and perspe ctives.
        D) American colleges and universities are a special property of NASA.
        
        40. What does Voss want to stress in the last paragraph?
        A) The technological significance of the program.
        B) The educational significance of the program.
        C) The philosophical significance of the program.
        D) The historical significance of the program.

        
        难句释疑(见下划线句子)
        【框架分析】 本句主干结构为:Voss...was assigned to...to analyze why... . why从句做analyze的宾语。〖ZK)〗
        【难句直击】本句中的术语为难点,如:propulsion推进;a hydraulic fuel p ump seal液压燃料泵的密封圈;a space shuttle航天飞机。
        【参考译文】 〖ZK〗Voss那时在西点军校担任科学教师,被派去阿拉马马州的马歇尔航 天飞行中心的推进实验室,分析为什么这次航天飞机的液压燃料泵的密封圈没出问题,而以 前的密封圈出了问题。
        
        答案精解 提纲挈领:本文为记叙文。主要讲述美国教师Voss从事空间飞行研究工作的情况。他一生共进行了三 次宇宙飞行和一次太空行走。最后一段谈到Voss对利用太空研究成果对青少年进行教育的看 法。
        
        36. C)。细节题。题意是:为什么液压燃料泵对航天飞机那么重要。
         迷途点津 A)因为以前的密封圈都出了问题;B)因为在实施航天项目时它非常复杂;C )因为必须十分注意液压燃料泵的密封性;D)因为密封圈上的任何裂缝对宇航员都会带来灾难性的后果。第一段最后一句的后半句为本题依据。原文中的 destructive对应选项C)中的d isastrous。
