As a Chinese student, you can send your application on July 14, 2017.BIn his new show, Evan Ruggiero plays guitar, sings pop standards and shows everybody his fine footwork. What makes all of these especially unusual is that Ruggiero, 24, has only one leg.When he was a 19-year-old musical theater student at New Jersey's MontclairStateUniversity, Ruggiero had a rare bone cancer in his right leg. Finallyhis leg would have to be amputated〔截〕below the knee.Such a setback could have easily ended the career of a less tough person, but Ruggiero, who has been dancing since he was five, now puts the experience into his performance. His show, "The One-Legged Song and Dance Man: Volume 3", explains how he returned to dance just 18 months after the amputation. His dance now relies on the use of a peg leg(假肢),he explains.The secret to his surprising success, he says, was being a "stubborn" patient who refused to give up on his dance and performing studies, despite the advice of his doctor.“It was a real setback, but after it was all over, I said, ' You know what? I need to pick up right where I left off and continue my career, '〞 Ruggiero said.Ruggiero has come to view his peg leg as an instrument. "Tap dancers-they're always calling themselves musicians, and their feet are their instrument," he said.Noting that many audience members will never have seen a one-legged dancer before coming to his show, Ruggiero says he won't shy away from the physical "weakness" his performance shows because of his condition."A lot of people have come up to me, and they always say, 'You're such a role model and an inspiration, '"he said. "I'm honored when people say that, of course, but I'm just trying to get on with my life."5. What makes Ruggiero's new show unusual?A. One-legged dance.B. His own artworks.C. The use of instrument.D. Songs of pop standard.6. According to the passage, it is true that__________.A. Ruggiero is a tough person with a strong willB. the setback has ended Ruggiero's dance careerC. Ruggiero is dancing relying on others' supportD. his doctor agreed he kept on dancing and studying7. When audience attend his performance, they may notice_______.A. Ruggiero plays piano, sings and dancesB. Ruggiero is a dancer with the help of a peg legC. there are many tap dancers in the performanceD. Ruggiero pretends to be a physically normal person8. What's the author's attitude to Evan?A. WorryB. SympathyC. EncouragementD. PityCIt is true that good writers rewrite and rewrite and then rewrite some more. But in order to work up the desire to rewrite，it is important to learn to like what you write at the early stage.I am surprised at the number of famous writers I know who say that they so dislike reading their own writing later that they even hate to look over the publishers' opinions. One reason we may dislike reading our own work is that we're often disappointed that the rich ideas in our minds seem very thin and plain when first written down. Jerry Fodor and Steven Pinker suggest that this fact may be a result of how our minds work.Different from popular belief，we do not usually think in the words and sentences of ordinary language but in symbols for ideas (known as ‘mentalese’ )，and writing our ideas down is an act of translation from that symbolic language. But while mentalese contains our thoughts in the form of a complex tapestry (织锦)，writing can only be composed one thread at a time. Therefore it should not be surprising that our first attempt at expressing ideas should look so simple. It is only by repeatedly rewriting that we produce new threads and connect them to get closer to the ideas formed in our minds.When people write as if some strict criticsare looking over their shoulder，they are so worried about what this critic might say that they get stuck before they evenstart. Peter Elbow makes an excellent suggestion to deal with this problem. When writing we should have two different minds. At the first stage，we should see every idea，as well as the words we use to express it，as wonderful and worth putting down. It is only during rewrites that we should examine what we excitedly wrote in the first stage and check for weaknesses.9. What do we learn from the text about those famous writers?A. They often regret writing poor works.B. Some of them write surprisingly much.C. Many of them hate reading their own works.D. They are happy to review the publishers' opinions.10. What do people generally believe about the way human minds work?A. People think in words and sentences.B. Human ideas are translated into symbols.C. People think by connecting threads of ideas.D. Human thoughts are expressed through pictures.11. What can we conclude from the text?A. Most people believe we think in symbols.B. Loving our own writing is scientifically reasonable.C. The writers and critics can never reach an agreement.D. Thinking and writing are different stages of mind at work.DEnergy independence. It has a nice ring to it. Doesn’t it? If you think so, you’re not alone, because energy independence has been the dream of American president for decades, and never more so than in the past few years, when the most recent oil price shock has been partly responsible for kicking off the great recession(经济衰退). “Energy independence〞 and its rhetorical (修辞的) companion “energy security〞are, however, slippery concepts that are rarely though through. What is it we wantindependence from, exactly?Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that old from elsewhere.The first reason is that we need it to keep our economy running. Yes, there is a trickle 〔涓涓细流〕of biofuel〔生物燃料〕available, and more may become available, but most biofuels cause economic waste and environmental destruction.Second, Americans have basically deci ded that they don’t really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports?Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don’t read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to maintain its economy. When that flow is interrupted, we feel the pain in short supplies and higher prices, At the same time, we derive massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.12. What does the author say about energy independence for America?A. It sounds very attractive. C. It will bring oil prices down.B. It ensures national security. D. It has long been everyone’s dream.13. What does the author think of biofuels?A. They keep America’s economy running healthily.B. They prove to be a good alternative to petroleum.C. They do not provide a sustainable energy supply.D. They cause serious damage to the environment.14. Why does America rely heavily on oil imports?A. It wants to expand its storage of crude oil.B. Its own oil reserves are quickly running out.C. It wants to keep its own environment undamaged.D. Its own oil production falls short of demand.15. What is the author’s purpose in writing the passage?A. To justify America’s dependence on oil imports.B. To arouse Americans’ awareness of the energy crisis.C. To stress the importance of energy conservation.D. To explain the increase of international oil trade.第二节(共5小题；每一小题2分，总分为10分)根据短文内容，从短文后的选项中选出能填入空白处的最优选项。

辽宁省沈阳市2018届高三教学质量监测(一)
辽宁省沈阳市2018届高三教学质量监测（一）辽宁省沈阳市2018届高三教学质量监测（一）第I卷(阅读题共70分)现代文阅读(35分)(一)论述类文本阅读(本题共3小题，9分)阅读下面的文字，完成1~3题。
书与人的随想梁衡人类社会是连续发展的，我们常将它比作历史长河，而每个人都是其中搭行一段的乘客。
我们上船之时，前人就将他们的一切发现和创造，浓缩在书本中，作为欢迎我们的礼物，同时也是交班的嘱托。
由于有了这根接力魔棒，所以人类几十万年的历史，某一学科积几千年而有的成果，我们可以在短时间内将其掌握，而腾出足够的时间去进行新的创造。
书籍是我们视接千载、心通四海的桥梁，是每个人来到这个世界上首先要拿到的通行证。
历史愈久，文明积累愈多，人和书的关系就愈紧密。
养生家说:健康是幸福，无病最自由。
这是讲作为物质的人。
作为精神的人正好与此相反。
他刚一降生，对这个世界一无所知。
于是就识字读书，读一本书就获得一份自由，读的书越多，获得的自由度就越大。
所以一个学者到了晚年，哪怕他是疾病缠身，身体的自由度已极小，精神的自由度却可达到最大，甚至在去世之后他所创造的精神世界仍然存在。
古代有人之初性恶性善之争。
我却说，人之初性本愚，只是后来靠读书才解疑释惑，慢慢开启智慧。
不读书的人无法理解读书人的幸福，就像足不出户者无法理解环球旅行者或登月人的心情。
既然书总结了人类的一切财富，那么读书就决定了一个人的视野、知识、才能、气质。
当然读书之后还要实践，高尔基说书籍是人类进步的阶梯，如果你脚下不踏一梯，那就只像一只不停创洞的土拨鼠，终其一生也不过是吃穿二字。
你可以自得其乐，但实际上已比别人少享受了半个世界。
古语言:读书知理。
谁掌握了真理谁就掌握了世界。
所以读书人最勇敢，常一介书生敢当天下。
像毛泽东当年就是以一青年知识分子而独上井冈，面对腥风血雨坚信能再造一个新中国，他懂得阶级分析、阶级斗争这个理。
像马寅初，敢以一朽老翁面对汹汹批判，而坚持到胜利。
