B The mon cold is the world’s most widespread illness, which is probably why there are more myths(神話，想象 ) about it than any of the other illnesses. The most widespread mistake of all is that colds are caused by cold． They are not． They are caused by viruses passing on from person to person． You catch a cold by ing into contact, directly or indirectly, with someone who already has one． If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever． But they do not． And in isolated Arctic regions explorers have reported being free from colds until ing into contact again with infected(感染的 ) people from the outside world by way of packages and mail dropped from airplanes． At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the disforts of being cold and wet for long stretches of time． After taking hot baths, they put on bathing suits, allowed themselves to be doused(浸入 ) with cold water, and then stood about dripping（滴干） wet in drafty（通風(fēng)的） rooms． Some wore wet socks all day while others exercised in the rain until close to exhaustion． Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose． If cold and wet have nothing to do with catching colds, why are they more frequent in the winter? In spite of the most painstaking research, no one has yet found the answer． One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on． No one has yet found a cure for the cold． There are drugs and pain suppressors such as aspirin, but all they do is to relieve the symptoms． 44． The fact that the Eskimos don’t suffer colds shows that .

C After giving a talk at a high school, I was asked to pay a visit to a special student. An illness had kept the boy home, but he had expressed an interest in meeting me. I was told it would mean a great deal to him, so I agreed. During the ninemile drive to his home, I found out something about Matthew. He had muscular dystrophy (肌肉萎縮癥 ). When he was born, the doctor told his parents that he would not live to five, and then they were told he would not make it to ten. Now he was thirteen. He wanted to meet me because I was a goldmedal power lifter, and I knew about overing obstacles and going for my dreams. I spent over an hour talking to Matthew. Never once did he plain or ask, “Why me?” He spoke about winning and succeeding and going for his dreams. Obviously, he knew what he was talking about. He didn’t mention that his clas smates had made fun of him because he was different. He just talked about his hopes for the future, and how one day he wanted to lift weights with me. When we had finished talking, I went to my briefcase and pulled out the first gold medal I had won and put it around his neck. I told him he was more of a winner and knew more about success and overing 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. S omeday when I get to the Olympics and win my own medal, I will show it to you.” Last summer I received a letter from Matthew’s parents telling me that Matthew had passed away. They wanted me to have a letter he had written to me a few days before: Dear Dick, My mum said I should send you a thankyou letter for the picture you sent me. I also want to let you know that 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 someday that I would go to the Olympics and win a gold medal, but I know now I will never get to do that. However, 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 48.
