1 我国的“神舟”五号载人飞船顺利地绕地球飞行14圈后胜利返回地面，做到人船安全着陆，这是我国航天史上的一个“里程碑”.其实飞船在飞行过程中有很多技术问题需要解决，其中之一就是当飞船进入宇宙微粒尘区时如何保持飞船速度不变的问题，我国科学家将这一问题早已解决，才使得“神舟”五号载人飞船得以飞行成功.假如有一宇宙飞船，它的正面面积为S="0.98" m 2,以v=2×10 3 m/s的速度进入宇宙微粒尘区，尘区每1 m 3空间有一微粒，每一微粒平均质量m=2×10 -4 g,若要使飞船速度保持不变，飞船的牵引力应增加多少？（设微粒尘与飞船相碰后附着于飞船上）

6 阅读理解。 "Mister D"Arcy is not a policeman. He is however, very wise. He knew the police would search his apartment. He also knew how police think. So, he did not hide the letter where he knew they would look for it. "Do you remember how Germont laughed when I said the mystery was difficult for him to work out because it was so simple?" Dupin filled his pipe with tobacco and lit it. "Well, the more I thought about it, the more I realized the police could not find the letter because D"Arcy had not hidden it at all. "So I went to visit D"Arcy in his apartment. I took a pair of dark green eyeglasses with me. I explained to him that I was having trouble with my eyes and needed to wear the dark glasses at all times. He believed me. The glasses permitted me to look around the apartment while I seemed only to be talking to him. "I paid special attention to a large desk where there were a lot of papers and books. However, I saw nothing suspicious there. After a few minutes, however, I noticed a small shelf over the fireplace. A few postcards and a letter were lying on the shelf. The letter looked very old and dirty. "As soon as I saw this letter, I decided it must be the one I was looking for. It must be, even though it was completely different from the one Germont had described. "This letter had a large green stamp on it. The address was written in small letters in blue ink. I memorized every detail of the letter while I talked to D"Arcy. Then when he was not looking, I dropped one of my gloves on the floor under my chair. "The next morning, I stopped at his apartment to look for my glove. While we were talking, we heard people shouting in the street. D"Arcy went to the window and looked out. Quickly, I stepped to the shelf and put the letter in my pocket. Then I replaced it with a letter that looked exactly like it, which I had taken with me. I had made it the night before. "The trouble in the street was caused by a man who had almost been run over by a horse and carriage.He was not hurt. And soon the crowd of people went away. When it was over, D"Arcy came away from the window. I said goodbye and left. "The man who almost had an accident was one of my servants(雇员). I had paid him to create the incident." Dupin stopped talking to light his pipe. I did not understand. "But, Dupin," I said, "why did you go to the trouble of replacing the letter? Why not just take it and leave" Dupin smiled. "D"Arcy is a dangerous man," he said. "And he has many loyal servants. If I had taken the letter, I might never have left his apartment alive." 1. What is Dupin probably? A. A captain. B. A detective. C. An official. D. A professor. 2. Why was Dupin wearing a pair of dark green eyeglasses while calling at D"Arcy"s ? A. Because he wanted to be look more handsome. B.
