Then I neednt have worked so hard in my late twenties and early thirties. But I just didnt know that. I was writing and writing. I was working for no other reason than to hear people praise me.Most people who go through university read at least twice as fast as I do. I can never tell my left from my right. I avoid dialing a telephone if I can help it, because I sometimes have to try three times before getting the number right. I hear that recording “The number you have reached is not in service” more than any man on earth.Despite my weaknesses I view my dyslexia (difficulty in reading) as a gift, not a curse(诅咒). Many dyslexics are good at right brain, namely abstract thought, and that is what my key of creative writing is. Im starting with nothing and ing up with something that didnt exist before. Thats my strong point. I owe my career to Ralph Salisbury, my writing instructor at the University of Oregon, who looked past my misspellings and gave me encouragement and hope. I just carried on and never looked back. Im also very “visual”. This means nothing in school, but when I write books or scripts, Im seeing everything in my imagination. I write quickly. I go like the wind and can get up to 15 pages a day. Writing is not the problem. I have no problem downloading; it is inputting where things get messed up.The real fear I have for dyslexics is not that they have to struggle with messy input, but that they will quit on themselves before they finish school. Parents have to create victories whenever they can, whether it is music, sports or the arts. You want your dyslexic child to be able to say, “Yeah, reading is hard. But I have these other things I can do.”36. From Paragraph 3 we can know that _A. The author was grateful to his writing instructorB. The author often plained about his dyslexiaC. The author had trouble with both inputting and outputting.D. Having problem in inputting, the author wrote slowly.37. For dyslexics, the author thinks that_.A. they should work as hard as himselfB. they had better choose to drop out of schoolC. they should be constantly encouragedD. they should put their hearts into reading38. Which of the following proverbs can best summarize the main idea of the passage?A. He who laughs last laughs best.B. Where there is a will, there is a way.C. Reading enriches the mind.D. When God closes a door, somewhere he opens a window.39. What kind of man is the writer?A. Open-minded and optimistic B. diligent and generousC. clever but selfish D. kind but useless【答案】36. A 37. C 38. D 39. A【解析】本文属于记叙文，描写了一个有阅读障碍的人在写作.上取得了极大的成功，本文告诉我们上帝为我们关上一扇门，就会给我们打开一扇窗。【36题详解】推理判断题。从文章的第三段I owe my career to Ralph Salisbury, my writing instructor at the University of Oregon, who looked past my misspellings and gave me encouragement and hope.可知我把我的事业归功于通过我的拼写错误并给予我鼓励与希望的导师Ralph, Salisbury，故选A。【37题详解】考查细节理解。根据最后一段The real fear I have for dyslexics is not that they have to struggle with messy input, but that they will quit on themselves before they finish school. Parents have to create victories whenever they can, whether it is music, sports or the arts. You want your dyslexic child to be able to say, “Yeah, reading is hard. But I have these other things I can do.”可知，不管是在音乐，体育或艺术上只要他们可以，家长就得给他们创造成功，故选C。【38题详解】推理判断题。文章描写了一个有阅读障碍的人在写作上取得了极大的成功，告诉我们上帝为我们关上一扇门，就会给我们打开一扇窗，故选D。【39题详解】推理判断题。A. Open- minded and optimistic思想开明和乐观的。B. diligent. And generous勤奋慷慨的。C. clever but selfish聪明但自私的。 D. kind, but useless善良但无用的。文章主要描写了一个有阅读障碍的人在写作上取得了极大的成功，故选A。BPreventing obesity and smoking can save lives, but it doesnt save money, reported researchers. “It was a small surprise, for it is against the mon belief,” said Pieter Van Baal, who led the study. “But it makes sense. If you live longer, then you cost the health system more.”The researchers found that from age 20 to 56, obese people racked up (累计) the most expensive health costs. But on average, healthy people lived 84 years. Smokers lived about 77 years, and obese people lived about 80 years. Smokers and obese people tended to have more heart disease than healthy people. Therefore in the long run, the thin and healthy group cost about $417, 000, from age 20 on. Smokers cost about $326, 000 and obese people $371, 000.“The result throws a bucket of cold water onto the idea, based on guesswork, that obesity is going to cost trillions of dollars,” said Patrick Basham, a professor of health politics. “If were going to worry about the future of obesity, we should stop worrying about its financial impact,” he said.“The benefits of obesity prevention may not be seen immediately in terms of cost saving in tomorrows budget, but there are long-term gains,” said Van Baal. “These are often immeasurable when it es to people living longer and healthier lives.” In the meanwhile, he said that governments should recognize that successful smoking and obesity prevention programs mean that people will have a longer chance of dying of something more expensive later in life.“Lung cancer is a cheap disease to treat because people dont survive very long. But if they are old enough to get Alzheimers (早老性痴呆症) one day, they may survive longer and cost more. We are not advising that governments stop trying to prevent obesity,” Van Baal said. “But they should do it for the right reasons.”40. Among middle-aged people, who may cost the health system most?A. Those who are heavy smokers. B. Those who are overweight.C. Those who are too thin. D. Those who are suffering from heart attacks.41. What can we know about the belief that obesity costs much?A. It turns out to be incorrect. B. It es from scientific study.C. It is based on medical evidence. D. It has changed over the past years.42. According to the text, governments prevent obesity for the purpose of _.A. reducing the risks of suffering cancerB. weakening obesitys financial impactC. making sure of peoples long and healthy lifeD. reducing the money spent on medical programs【答案】40. B 41. A 42. C【解析】本文属于说明文，介绍了防治肥胖和吸烟能使我们活得更长，但是却不能省钱，可能会花的更多。【40题详解】细节理解题。根据第二段The researchers found that from age 20 to 56, obese people racked up (累计) the most expensive health costs.可知是肥胖人群。故选B。【41题详解】推理判断题。根据第三段“The result throws a bucket of cold water onto the idea, based on guesswork, that obesity is going to cost trillions of dollars,” said Patrick Basham, a professor of health politics.该研究对于我们已有的猜测泼了一盆冷水，故选A。【42题详解】细节理解题。根据倒数第二段These are often immeasurable when it es to people living longer and healthier lives.” In the meanwhile, he said that governments should recognize that successful smoking and obesity prevention programs mean that people will have a longer chance of dying of something more expensive later in life. 可知，政府防治肥胖是为了让人们能更健康的生活，并且活得更久，故选C。CBritains most popular lie has been disclosed, with one in four people admitting using “sorry I had no signal when returning a missed mobile phone call, a survey found.Researchers found the average Briton tells on average four lies every day or almost 1500 every year. Almost one in six men admitted they were most likely to lie to their wife or girlfriend, on average at least
