高中英语Unit1 Great scientists文章 哥白尼人教版必修五
哥白尼一、生平简介哥白尼〔1473～1543〕是波兰天文学家，日心说的创始人。
1473年2月19日生于波兰东部的托伦。
他的父亲是一位曾经当过市长的商人，母亲是一位富商的女儿。
哥白尼有一个哥哥和两个姊姊，他是家中最小的孩子。
在他10岁时，父亲染上瘟疫死亡。
全家由舅父务卡施接济。
哥白尼在文化名城沃茨瓦维克读了中学，1491哥白尼进入克拉科夫雅盖隆大学，在天文学家勃鲁泽夫斯基的指导下研读天文学和数学。
1496年，为了进一步深造，哥白尼前往欧洲文艺复兴的中心意大利留学，先后就读于波伦亚大学、帕多瓦大学和法拉腊大学，继续钻研数学、天文学、医学和法学。
他有幸结识了文艺复兴的杰出人物达·芬奇，并且拜敢于向旧观念挑战的学者诺瓦拉〔1454—1504〕为师。
正是在诺瓦拉的影响下，他开始对地心说产生了怀疑。
1506年哥白尼回到波兰，一面在里兹堡从医，一面从事天文学的研究。
1512年舅舅去世，哥白尼移居弗洛恩堡，在大教堂任僧正。
教堂城墙的一角有座箭楼，哥白尼用它建立了一个小天文台。
他自制了各种仪器，孜孜不倦地从事天文观测和研究达30多年。
他在1510年写成的《浅说》初稿中，毫不含糊地指出：太阳是宇宙的中心体，地球和行星都围绕着太阳运动，只有月亮才真正围绕地球旋转。
1530年，终于圆满地完成了日心说的建立工作。
于1543年3月用《天体运动论》书名出版，全书共有六大卷。
由于呕心沥血的辛勤劳动，从1542年起哥白尼健康日益恶化，经常出血、中风。
1543年5月24日，哥白尼与世长辞，终年70岁。
据说他闭目的时候，还用冰冷的双手抚摸着刚刚印好的《天体运动论》样书。
二、科学成就哥白尼在科学上最大的成就是创立了以太阳为中心的地动学说〔日心说〕，否定了在西方统治达一千多年的以地球为中心的地静学说〔地心说〕。
哥白尼创立的日心说，即名著《天体运行论》的发表，不但是天文学上的一次伟大革命，推动了天文学研究的飞速发展，而且引起了人类宇宙观的重大革新，沉重地打击了封建神权的统治，“从此自然科学便开始从神学中解放出来〞三、趣闻轶事1．人小志大哥白尼从小受到良好的学校教育，喜欢观察天象。

AMy senior year of high school was a very hectic one, to say the least. If I wasn´t studying or worrying about my grades, I was working on after-class activities. It seemed as if my life had turned into one crazy cloud of confusion and I hoped to find some sort of direction.Finally, I got a part-time job at the local coffee shop. I had thought it would be easy and, for the most part, stress-free. I pictured myself pouring coffee and becoming close friends with my customers.What I hadn´t expected were the people with so many orders. There were moments when I was very angry simply because I couldn´t seem to please anyone. There was always too much sugar, too little ice, or not enough skim milk. However, I kept at it.One day, one of my customers came in, depressed. Before he left, I handed him a bag along with his iced coffee. He looked at me questioningly because he hadn´t ordered anything but the coffee. He opened the bag and saw his favourite doughnut (甜甜圈) I had given him. He smiled and thanked me before heading out into the rain.The next evening, he came. Instead of ordering something, he handed me a single pink rose and a note.“Thanks for being so sweet and thoughtful yesterday. It is so nice to meet someone who´s warm and unselfish. Please don´t change your ways because I truly believe that you will do better. Have a great day!”As time went on, I did come across some customers really particular. But anytime I felt depressed, I thought of that man and his kindness. Then I would smile, hold my head up high, clear my throat and ask politely, “How can I help you?”1.What does the underlined word “hectic” in Paragraph 1 mean?A. Glad.B. Interesting.C. Productive.D. Busy.2.What can we know about the author´s part-time job?A. It is easy and stress-free.B. It is quite busy and challenging.C . It doesn´t need special skills. D. It gives the author a feeling of freshness.3.What´s the message the author wants to convey?A. Kind words are worth much but cost little.B. It is impossible to satisfy everyone in our life.C. A small act of kindness can make a big difference.D. Our attitude determines our suffering or our freedom.BAn idea that started in Seattle´s public library has spread throughout America and beyond. The idea is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time.In addition to encouraging reading as a pursuit(爱好) to be enjoyed by all, theprogramme allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched (发起)the “If All of Seattle Read the Same Book” project in 1998. Her original programme used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.In Chicago, the mayor appeared on television to announce the choice of To Kill a Mockingbird as the first book in the “One Book, One Chicago” programme. As a result, reading clubs and neighbourhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and characters.The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity(一致)can be achieved.Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself.As Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process or have enjoyed speaking to someone with whom they would not otherwise have shared a word.4.What is the purpose of the project launched by Nancy?A.To invite authors to guide readers.B.To encourage people to read and share.C.To involve people in community services.D.To promote the friendship betweencities.5.Why was it difficult for New Yorkers to carry out the project?A.They had little interest in reading.B.They were too busy to read a book.C.They came from many different backgrounds.D.They lacked support from the local government.6.The underlined words “shared a word” in Paragraph 5 probably mean .A.exchanged ideas with each otherB.discussed the meaning of a wordC.gained life experienceed the same languageCScientific experiments can sometimes go wrong and when they do, the results may range from the disastrous (灾难性的) to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country´s bees. He imported a very active type of African bee from Tanzania and mated (交配) it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, which was the scientist´s name, had a total success on his hands.Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry. They attacked the native bees and drove them from their living places.But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (刺), began to attack their neighbours—cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings.This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them.7. The results of the South American experiment .A.are not importantB.are not yet certainC.have caused a serious troubleD.have proved to be wrong8. The experiment mentioned in this passage was designed to .A.make African bees less activeB.increase the number of bees in BrazilC.make Brazilian bees more easy-goingD.increase the amount of honey in Brazil9. Which of the following may be the cause of the new bees´ attacking personalities?A.Their bad temper.B.Their hard work.C.Their production of honey.D.Their living environment.10. The last paragraph implies that .A.the bees prefer to live in BrazilB.the bees must be stopped from moving northC.the bees may bring about trouble in more countriesD.the bees have been driven to Central and North America第二节阅读七选五(共5小题;每小题2分,满分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佳选项。

高中英语Unit1 Great scientists文章 哥白尼与日心说人教版必修五
哥白尼与日心说尼古拉．哥白尼（Copernicus Nicholas），波兰一位伟大的天文学家。
他以惊人的天才和勇气揭开了宇宙的秘密，奠定了近代天文学的基础。
哥白尼以毕生的精力去进行天文研究，创立了《天体运行论》这一“自然科学的独立宣言”。
他的这些成就使他成为了人类科学发展历史上最伟大的革命家之一。
一. 哥白尼生平哥白尼于1473年2月19日出生在波兰西部维斯杜拉河畔托伦城的一个商人家庭。
家里兄妹四个，哥白尼是最小的。
在他10岁时，父亲去世了，舅父卢卡斯承担起了抚育他的重任。
1491年至1495年，哥白尼进入克拉科夫大学学习。
克拉科夫是当时波兰的首都，也是东欧最大的贸易和文化中心，有许多国家的留学生在这里学习。
由于它地处东西欧交通要冲，所以比较早地受到意大利文艺复兴的影响。
因此在这座古老的大学里，新兴的资产阶级人文主义思想和腐朽的封建教会的经院哲学之间展开了激烈的斗争。
哥白尼在先进的人文主义思想的熏陶下，在心灵里埋下了向经院哲学挑战的种子。
在这里，他遇到了对他的一生产生深远影响的数学家和天文学家布鲁楚斯基（Brudzewski）教授。
是这位教授的启蒙教育促使哥白尼决定将自己的一生奉献给天文科学。
1496年哥白尼前往意大利求学，先后进入博洛尼亚大学、帕多瓦大学和费拉拉大学学习和研究法律、天文学、数学、神学和医学，他同时还学会了希腊文。
1503年，哥白尼获得了教会法规博士学位。
1497年，哥白尼就任瓦尔半米亚牧师的僧正。
1510年后，他先后从事过管理、外交等工作。
他是一个杰出的经济学家，写过《货币的一般理论》一书。
他是近代第一个提出劣币淘汰良币理论的经济学家。
哥白尼医术高明，他利用业余时间行医，免费为穷苦人治病，是一位颇有名望的医生，被人们誉为“神医”。
哥白尼还是一位出色的数学家，他的巨著《天体运行论》附录里，发表过他的球面三角论文。
哥白尼也是一位伟大的爱国主义者，当条顿骑士团疯狂侵略波兰时，他挺身而出，起来保卫自己的祖国。
