BGrowing up in rural Malawi, Africa, William Kamkwamba learned to accept that life was hard. He lived with his parents and seven sisters in a small clay house without electricity or running water. Like most boys in his village, William was expected to assist his parents on the family farm, as well as keep up with his school work. Each night, like most Malawians, his family went to bed early because the kerosene oil they needed to light the lamps was costly. When he was 10, a terrible drought left many Malawians hungry and Williams family was no exception. At the age of 13, William and many other children were forced to drop out of school when their parents could no longer afford his schooling. William had to work even harder to help his family, but he wasnt ready to give up his education. He went to the local library and took out some books to study. One book, called Using Energy,sparked Williams interest in science and gave him an idea that significantly changed his future. In the book, William found a picture of a windmill (风车),and a brief description of how it could be used to generate electricity from wind. He knew that there was plenty of wind in his village, and realized that if he could build a windmill like that, he could give his family and the people in his village a much better life. There was just one problem. The book didnt explain how to build a windmill, and neither did any of the other books in the library. What happened over the next year demonstrated Williams incredible ambition and determination. He began to collect any kinds of materials he thought could be usefulscraps of wood, broken bicycles, old shoesand started to build a windmill next to his familys house. He endured many challenges and failures. Other people in his village called him crazy and said his idea would never work. Finally, at the age of 14, William completed his first windmill. When they saw electric lights and heard the sound of music on the radio coming from Williams house, the village people came running. He had done it. William Kamkwamba had found a way to capture the wind. Kamkwambas autobiography (自传) ,The Boy Who Harnessed the Wind, tells the story of how the rest of the world came to know about his achievements. With the help of international supporters, his village now has clean running water, solar powered lighting, and electric power. As a result of his actions, Kamkwamba was invited to study engineering at Dartmouth College, one of the top-ranking universities in the U. S. He also travels the world and gives talks about how he made his dream a reality. 44. William went to the local library because _. A. he wanted to find some materials for his invention B. it was his favorite way to kill time and relaxC. it was believed to be a way to change his fateD. he wanted to continue his education45. Paragraph 3 is mainly about _. A. why the windmill is so attractive B. how William got inspired by a bookC. why William decided to continue his education D. how a windmill works to produce electricity46. William Kamkwamba can be best described as _. A. brave and patient B. honest and forgiving C. ambitious and determined D. reasonable and humorous47. What is the message conveyed in the passage?A. We should strike while the iron is hot. B. A good beginning makes a good end. C. One who lives his dream can make a difference. D. Youd better not put all the eggs in one basket. CCyclingYou need only look at a professional cyclist to appreciate the potential effects of cycling on the body. But what about the mind? Its a question that has long challenged anyone who has wondered how riding a bike can offer what feels close to a state of emptying your mind. Dr. John Ratey thinks cycling increases “the chemistry in your brain that makes you feel calm,” but also that carrying out multiple operations while cycling can be an effective treatment, as shown in a German study involving 115 children, half of whom did activities such as cycling that involved complex movements, while the rest performed more straightforward exercises with the same aerobic (有氧的) demands. Both groups did better than they previously had in concentration tests, but the “complex” group did a lot better. There have been other interesting findings too. In 2003, Dr. Jay Alberts rode a tandem bicycle, a bicycle built for two riders sitting one behind the other, across the American state of Ohio with a friend who has Parkinsons (帕金森) disease, a condition affecting the nervous system. The idea was to raise awareness of the disease, but to the surprise of both riders, the patient showed significant improvements. Dr. Jay Alberts then scanned the brains of 26 Parkinsons patients during and after an eight-week exercise programme using bikes. Half the patients were allowed to ride at their own paces, while the others were pushed harder. All patients improved, and the group which was pushed harder showed particularly significant increases in connectivity between areas of intelligence responsible for functions such as walking and picking things up. We dont know how this happens, but there is more evidence of the link between Parkinsons and cycling. A video on the Internet shows a 58-year-old man with severe Parkinsons. At first, we watch the patient trying to walk. He can barely stand and his hands shake uncontrollably. Then we see the man on a bicycle being supported by others. With a push, hes off, cycling past cars with perfect balance. Doctors dont fully understand this discrepancy either, but say that cycling may act as some sort of action that helped the patients brain. The science of cycling is incomplete, but perhaps the most remarkable thing for the everyday rider is that it can require no conscious focus at all. The mindlessness of cycling can not only make us happier, but also leave room for other thoughts. On the seat of my bike, Ive solved problems at work and made life decisions, as, Im sure, have countless others. 48. What does the study described in Paragraph 2 suggest?A. Cycling has a good effect on physical fitness.B. The tasks involved in cycling can be hard for children.C. Lack of exercise like cycling causes lack of concentration.D. Cycling can improve the ability to focus attention on a task.49. Studies of people with Parkinsons show that _.A. cycling on tandem bikes has a better effect on the diseaseB. cycling does more good if sufferers put more effort into itC. not every person with Parkinsons will benefit from cyclingD. social awareness is more important for Parkinsons sufferers50. What does the underlined part “this discrepancy” in Paragraph 4 re
