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 (填满) 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 (下降) 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 further 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 lane 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. [br] This passage was written to

选项 A、encourage young people to take up science.
B、describe the process of a scientific competition.
C、show scientists what young people can do.
D、report on a new scientific technique.

答案 B

解析 考查写作意图。第l至2段对作为实验活动场所的飞机进行介绍;第3至4段讲挑选参加者的过程,并对实验进行大致说明;第5至6段描述此次活动的详细经过,最后一段说明学生在此次活动后的感受。由此可见,文章的笔墨均用于介绍本次科学实验活动,故B为本题答案。文中均为客观描述,并没有暗示目标受众是什么人,A所述针对年轻人,C针对科学家,故A、C均可排除。文章从头至尾讲述的是一次科学活动,并非介绍什么新技术,且用于实验的飞机造于1964年,不能算是“新科技”,故排除D。
