问题     It looked just like another aircraft from the outside. The pilot told his young passengers that it was built in 1964. But appearances were deceptive, and the 13 students from Europe and the USA who boarded the aircraft were in for the flight of their lives.
    Inside, the area that normally had seats had become a long white tunnel. Heavily padded from floor to ceiling, it looked a bit strange. There were almost no windows, but lights along the padded walls illuminated it. Most of the seats had been taken out, apart from a few at the back, where the young scientists quickly took their places with a look of fear.
    For 12 months, science students from across the continents had competed to win a place on the flight at the invitation of the European Space Agency. The challenge had been to suggest imaginative experiments to be conducted in weightless conditions.
    For the next two hours, the flight resembled that of an enormous bird which had lost its reason, shooting upwards towards the heavens before rushing towards Earth. The invention was to achieve weightlessness for a few seconds.
    The aircraft took off smoothly enough, but any feelings that I and the young scientists had that we were on anything like a scheduled passenger service were quickly dismissed when the pilot put the plane into a 45-degree climb which lasted around 20 seconds. Then the engines cut out and we became weightless. Everything became confused and left or right, up or down no longer had any meaning. After ten seconds of free-fall descent the pilot pulled the aircraft out of its nosedive. The return of gravity was less immediate than its loss, but was still sudden enough to ensure that some students came down with a bump.
    Each time the pilot cut the engines and we became weightless, a new team conducted its experiment.
    First it was the Dutch who wanted to discover how it is that cats always land on their feet. Then the German team who conducted a successful experiment on a traditional building method to see if it could be used for building a future space station. The Americans had an idea to create solar sails that could be used by satellites.
    After two hours of going up and down in the plane doing their experiments, the predominant feeling was one of excitement rather than sickness. Most of the students thought it was an unforgettable experience and one they would be keen to repeat.
According to the text, the purpose of being weightless was________.
选项 A、to see what conditions are like in space
B、to prepare the young scientists for future work in space
C、to show the judges of the competition what they could do
D、to make the teams try out their ideas
答案D
解析 本题的问题是：为什么要进入失重状态?定位到第六段。根据第六段第一句，每次飞行员关掉引擎，大家就会失重(became weightless)，此时就会有新团队开始进行实验，后面几句讲的是荷兰、德国和美国团队进行的实验，荷兰人想弄清楚为什么猫总是会脚着地，德国团队用传统的建造方法进行了一次成功的实验，他们想看它是否可以用于建造未来的空间站(space station)，美国人的想法是制造用于卫星的太阳帆(solar sails)。即各国团队利用失重状态进行实验，在实践中检验自己的构思，因此，选项D与原文属于相同含义，为正确选项。根据第三段第二句，此次挑战是在失重条件下进行富有想象力的实验，因此进入失重状态不是简单地为了体验太空环境，而是要提供实验的条件，所以选项A曲解文意。文中没有提到这些学生今后会从事太空工作，所以选项B属于主观推导。原文没有提及裁判一词，也没有展示能力的说法，所以选项C属于无中生有。第六段：各国团队进行失重实验。
