An illness had kept the boy home, but he had expressed an interest in meeting me, and it would mean a great deal to him. I agreed. He was Matthew. When he was born, the doctor told his parents that he would not live to see five, then they were told he would not make it to ten. Now he was thirteen. He wanted to meet me because I was a gold-medal weight lifter, and I knew about overcoming obstacles and going for my dreams. I spent over an hour talking to Matthew. Never once did he complain. He spoke about winning and succeeding and going for his dreams. Obviously, he knew what he was talking about. He just talked about his hopes for the future, and how one day he wanted to lift weight with me. When we finished talking, I went to my briefcase and pulled out the first gold medal I won and put it around his neck. I told him he was more of a winner and knew more about success and overcoming obstacles than I ever would. He looked at it for a moment, then took it off and handed it back to me. He said, "You are a champion. You earned that medal. Someday when I get to the Olympics and win my own medal, I will show it to you." Last summer I got the news that Matthew had passed away and a letter Matthew had written me a few days before: Dear Rick, My mom said I should send you a thank-you letter for the picture you sent me. The doctors tell me that I don't have long to live any more. But I still smile as much as I can. I told you some day I was going to the Olympics and win a gold medal. But I know now I'll never make it. But I know I'm a champion, and God knows that too. When I get to Heaven, God will give me my medal and when you get there, I will show it to you. Thank you for loving me. Your friend, Matthew Question: What can be inferred from Matthew's letter? Options: A: Rick was unhappy before death. B: Rick kept in touch with Matthew. C: Matthew sent some pictures to Rick. D: Matthew got an Olympic gold medal.

But Lee Gray, PhD, of the University of North Carolina, the US, has made it his business to examine this overlooked form of public transport. He is known as the "Lift Guy". "The lift becomes this interesting social space where etiquette is sort of odd ," Gray told the BBC. "They (Lifts) are socially very interesting but often very awkward places." We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, lift users unthinkingly go through a set pattern of movements. He told the BBC what he had observed. He explained that when you are the only one inside a lift, you can do whatever you want--it's your own little box. If there are two of you, you go into different corners, standing diagonally across from each other to create distance. When a third person enters, you will unconsciously form a triangle. And when there is a fourth person, it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle. New entrants to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple--look down, or look at their phones. Why are we so awkward in lifts? "You don't have enough space," Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. "Usually when we meet other people, we have about an arm's length of distance between us. And that's not possible in most lifts." In such a small, enclosed space it becomes very important to act in a way that cannot be construed as threatening or odd. "The easiest way to do this is to avoid eye contact,"she said. Question: According to Gray, when people enter a lift, they usually _ . Options: A: turn around and greet one another B: look around or examine their phones C: make eye contact with those in the lift D: try to keep a distance from other people

While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years. European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month. _ Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004. A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex. "It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia. Just like bears and frogs, the hibernation of human beings would cause a person's metabolism to lower so they would need less energy. Medical research, however, is just half of a space flight hibernation system. There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor life functions and serve the physiological needs of the hibernator. According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.
