Passage Five

　　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(填塞) 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 lose 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 become 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 conduct it experience. 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 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 predominate 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.

　　Part Ⅳ Cloze (15 minutes, 15 points, 1 for each)

　　Directions: In this part, there is a passage with 15 blanks. For each blank there are 4 choices marked A, B, C and D. Choose the best answer for each blank and mark the corresponding letter on your ANSWER SHEET with a single line through the center.

　　Most people who travel long distances complain of jetlag (喷气飞行时差反应). Jetlag makes business travelers less productive and more prone __61__ making mistakes. It is actually caused by disruption of your "body clock"一 a small cluster of brain cells that controls the timing of biological __62__. The body clock is de-signed for a __63__ rhythm of daylight and darkness, so that it is thrown out of balance when it experiences daylight and darkness at the "wrong" times in a new time zone. The __64__of jetlag often persist for days __65__ the internal body clock slowly adjusts to the new time zone.

　　Now a new anti-jetlag system is __66__ that is based on proven extensive pioneering scientific research.

　　Dr. Martin Moore-Ede has devised a practical strategy to adjust the body clock much sooner to the new time zone __67__ controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates __68__ of the discomfort of jetlag.

　　A successful time zone shift depends on knowing the exact times to either __69__ or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule __70__ light exposure depends a great deal on__71__ travel plans.

　　Data on a specific flight itinerary (旅行路线) and the individual's sleep__72__are used to produce a Trip Guide with__73__on exactly when to be exposed to bright light.

　　When the Trip Guide calls __74__ bright light you should spend time outdoors if possible. If it is dark outside, or the weather is bad, __75__ you are on an aero plane, you can use a special light device to provide the necessary light stimulus for a range of activities such as reading, watching TV or working.
