Reading Comprehension (阅读理解)：(共50分)A) Choose the best answer (根据文章内容，选择最恰当的答案)：(12分)Traditionally, the President is the highest-pad public employee. A salary of $ 400,000, along with other benefits, is paid to the President annually. But President Obama’s income for 2008 was far more than that, according to the White House.The White House recently published the tax returns (纳税申报单)of Obama and Vice –president Joe Biden. Tax returns are reports of tax that a person has to pay. They often include income information used to calculate the tax. In the US, people whose incomes are over a certain amount have to file tax returns(纳税申报)every year. The tax returns of government officials are open to the public. This transparency helps to prevent corruption(腐败)。From Obama’s tax returns , we can see that the President and first lady President’s two books Dreams From My Father and The Audacity of Hope(《无畏的梦想》). The two books, published in 1995 and 2006,are very popular and have been on the bestseller(畅销书)list for a long time.The Obama’s income is down from 2007,when they made ＄4.2 million. However, that is still far more than former US President George Bush earned, who reported a total of ＄719,274 for his final year. The Obamas’ income also greatly exceeded(超出)that of Biden, who reported a family income of ＄2269,256.That’s about a tenth of what the Obamas earned. As Vice-president, Biden earns a salary of ＄220,000.US families earn an average income of about ＄50,000.The Obama’s tax returns also show that together, the President and his wife paid about ＄933,000 in taxes. They gave $172,050 —nearly 6.5 percent of their earnings —to different charity groups. In the US, if a person gives his money to churches and non-profit(非盈利)organizations, the law reduces his or her taxes. This is one reason why rich people in the US like to give money to charity.74. _______had the highest income in 2008.A. Obama B. Biden C. Bush D. George75. How much did Obama and his wife earn in 2008 A. $400,000 B. $2,660,000 C. $4,200,000 D. $719,27476. In the US, which people have to file tax returns A. EverybodyB. Wealthy peopleC. Government officialsD. People whose incomes are over a certain amount.77. The Obamas have given_______ percent of their earnings to charity.A. 10 B. 6.5 C. 9.7 D. 4.378.Why should the tax returns of government officials be open to the public .A. Because it can help to prevent corruptionB. Because it can make government officials well-known to the public.C. Because it can help government officials to get more money.D. Because the government wants them to pay more taxes to the public.79. According to the law, if a rich man gives his money to charity,_______.A. he will be praised by the peopleB. he will pay fewer taxesC. he will be free of taxesD. he will get some extra money from the government.B) Choose the words or expressions to complete the passage(选择最恰当的单词或词语，完成短文)：(12分)For many years the United States and the other countries used gold and silver as money. Papermoney was used to stand for the holdings(储备)of both gold and silver. The value of silver waslimited to that of gold. Fifteen ounces(盎司) of silver had the same value of one ounce of gold.These values did not change until after 1860 when mines(银矿)in the west of the United Statesbegan to 80 large amounts of silver. This extra amount of silver caused the price of silver to81 . Then fifteen ounces of silver would no longer buy one ounce of gold. In 1871 Germanydeclared(宣布)that it would not support its paper money with silver any more. Instead, it would use only gold. Other countries of Europe quickly 82 the same. The United States passed a law in 1973 that prevented the government from using silver as money. Western silver producers protested(抗议)loudly and put much pressure on the 83 makers. Five years later a new law was 84 . It said that the government must buy four and half million ounces of silver each month. The new law increased the amount of silver money. The country had two kinds of quite different views on the issue(发行)silver money. Businessmen, bankers and other rich men wanted to 85 the use of silver money because it made the dollar less valuable. But farmers, labourers and the others who owned the money not only wanted silver money but also wanted an unlimited supply of it.80. A. produce B. find C. search D. dig81.

For more than forty years , it was the tallest building in the world.It has one hundred and three levels and six thousand five hundred windows. Visitors can ride in one of seventy-three elevators that take them from the b__87__ to very near the top of the building. Some of these elevators are very fast, reaching the eightieth floor in only forty-five seconds.The heads of government of almost every n__88___ in the world have visited the Empire State Building. These important people are just a few of million who have ridden to the observation area near the top of the building each year. From there, visitors can see almost all of New York City. They can see the view a __89__ the Hudson River into the state of New Jersey. They can see ships in the East River.Even if you have never visited New York, there is a good chance for you to see the Empire State Building. It has been photographed c __90__ times. It has even played parts in movies. One is about a huge ape(猿)that escapes and climbs to the top of the building. The movie is “King Kong”(金刚). It was made in 1933. The Empire State Building also appeared in the love story “An Affair to Remember”(金玉盟).Cary Grant and Deborah Kerr play a man and a woman who meet and fall in love on a ship. They are looking at the New York City skyline from the ship when they plan a future meeting.More recently, in “Sleepless in Seattle(西雅图未眠夜)”，two people in love agree to meet at the Observation Deck on Valentine’s Day(情人节). B__91__ do arrive, but one is a little later. They almost m __92___each other.In the early nineteen seventies, the Empire State Building lost its place as the tallest building in New York. People in the city then had the Twin Towers of the World Trade Center to look up to. Tragically that all changed on the morning of September 11,2001. Terrorists hijacked(劫持) passenger airplanes into the Twin Towers and destroyed them. The Empire State Building again has become the city’s tallest building.D)Answer the questions (根据短文内容回答下列问题)：(12分)I’ve always wanted to try rock climbing, but never had time or money for it. But I’ve discovereda way to experience the thrill(兴奋，紧张) of climbing rock. Indoor climbing is an easy and excitingway to get a taste of rock climbing. And it is also much cheaper and safer! Indoor climbers don’tclimb on real rock, but on a plastic wall. You can probably find a climbing wall near you. Many gyms,schools and camps have one.You can climb in doors at any time of the year, no matter how the whether is. It is usually notexpensive. Most gyms provide the equipment you need. The convenience of indoor climbing isone reason why it has become so popular. But the main reason people climb is for rush(刺激感) they get. When I stand at the roof of the wall and look up, I’m always scared, but once I start climbing, fear changes to determination. With my heart pounding(心剧烈跳动), I reach the top and look down. I can’t stop grinning. I did it!Indoor climbing is a great workout(锻炼). Climbing uses muscles(肌肉)that are hard to exercise, especially those in the shoulders, arms, chest and back. Many people say climbing makes exercise fun. Most gyms have several climbing walls with various degrees of difficulty. The easier ones are like climbing a ladder. The difficult ones bulge out(凸出)in places so that climbers must sometimes climb parallel(平行的)with the floor.Although gym climbing is easier and safer than real rock climbing, you should still be careful. Always climb with a partner. As you climb, your partner pulls you climbing rope through something called a belay device(绳索控制器). The belay catches you if you slip.

In Tokyo, there are always too many people in the places. There are also too many cars. Tokyo drivers often spend a long time in the busy street, just like drivers in London, Paris and New York.Tokyo also has a lot of people on foot, and sometimes it is really difficult to walk in the street. The worst time in the street is at 11:30 at night. That is because the nightclubs are closing at that time and everybody wants to go home then. There are 35,000 nightclubs in Tokyo, and usually none of them is empty at night.During the day, most people go to work by train. Six million train tickets are sold every week in Tokyo. At most stations, trains arrive every two or three minutes, but at certain hours it is not enough at all. Although trains are always crowded, they are very good in many ways. They always leave and arrive on time. But in Tokyo trains, everybody seems to be sleepy, no matter whether his journey is long or short.(17. T 18. T 19. F . 20. T 21. F 22. F 23. F)IV.

He was not among the best students at school, and he often got into trouble with either his classmates or his teachers. But he was full of new ideas, which few people could see the value of. Things were still the same when he went up to college and he dropped out (辍学)halfway.Steven Jobs worked first as a video game designer at Atari. He worked there for only a few months and then he travelled to India. He hoped that the trip would give him more ideas and a change in life for the better.After he had returned from India, he began to live on a farm in California. And then, in 1975, Steven Jobs began making a new type of computer. Along with his friend Stephen Woziak, he designed the Apple I computer in his bedroom and in fact built it in his garage. He chose the name "Apple" because he thought of a happy summer he once spent in an orchard in Oregon.His Apple computer became such a great success that Steven Jobs became famous, Today Apple computer and iphone are very famous all over the world.(24. trouble 25. of 26. first 27. hoped 28. farm 29. making 30. success)Part 2 Vocabulary and GrammarV.

1分由于地沟油的密度在正常食用油密度范围之内，因此不能用密度这一指标来鉴别地沟油。 1分21．（8分） ⑴∵ 由图a可知： R1、R2并联，且电流表A串联在干路上、电流表A1与电阻R1串联在支路上。∴ 电流表A的示数比电流表A1的示数要大，∴ 根据图b可以判断出通过R1的电流I1＝0.3安、电路中的总电流I总＝1.5安。 1分∴ U总＝U2＝ U1＝I1×R1 1分＝0.3安×20欧＝6伏。 1分⑵ ∴ I2＝I总﹣I1＝1.5安﹣0.3安＝1.2安。 1分∴ R2＝ 1分＝＝5欧。 1分⑶若通过滑动变阻器的电流为它允许通过的最大电流为2安（此时通过R1的电流仍为＝0.3安不变、电路中的总电流变为I′总＝2.3安，没超过电流表A的量程3安。），所以滑动变阻器接入电路的最小电阻R2最小＝U2/ I2最大＝6伏/2安＝3欧。

辣椒中含有一种被称为辣椒素的物质，能够刺激皮肤和舌头上感觉痛和热的区域，使大脑产生灼热疼痛的辛辣感觉。科学家对生长在美国亚利桑那州南部沙漠地带的一种野生辣椒进行研究，观察有哪些动物以辣椒为食。结果发现，生活在附近的沙漠鼠类等小型哺乳动物根本不碰这种辛辣食物，吃辣椒似乎是鸟类的专利。实验表明，辣椒果实被小型哺乳动物吃掉之后，种子经消化排出，几乎不能再发芽。而鸟类的消化系统基本不对辣椒种子造成伤害。科学家认为，辣椒之所以辣是出自保护自己的需要。辣椒不想让哺乳动物把它们的果子吃掉，所以才在辣椒果子里产生了辣椒素，这样，吃不了辣的哺乳动物就会放弃，而鸟类却丝毫吃不出半点辣味，它们的痛觉感受系统和哺乳动物不一样，辣椒素能给它们清爽的感觉，还有止痛的功效。所以鸟类吃辣椒来像在嚼口香糖，而果实中的辣椒籽则会经过鸟类的肠道完整地排泄出来，完成一次又一次播种。③不少人吃辣椒会上瘾，这又是为什么呢？这是因为当辣椒的辣味刺激舌头、口腔的神经末梢时，机体的神经系统反射性地出现心跳的加速、唾液及汗液分泌的增加、肠胃挪动的增快等现象。同时兴奋性的刺激会使大脑释放出内啡肽，再吃下去，大脑又会以为有痛苦袭来，于是释放出更多的内啡肽。内腓肽促进大脑内另一种物质——多巴胺的分泌。多巴胺是一种脑内分泌物，相当于人体内“奖励系统”的物质基础，是一种类似肾上腺素的物质，可以影响一个人的情绪，在短时间内令人高度兴奋。于是享乐主义的大脑热让我们吃辣吃上瘾，以至于闻到浓郁的辣味就有进食的冲动。④那么， 科学家们发现，生活在炎热气候条件下的人们更喜欢吃辣椒——尽管生活在寒冷和潮湿地区的人们也都适合吃辣椒。这是因为他们知道辣椒能够抑制食物中有害细菌的滋生，防止食物中毒。⑤为了抑制食物中的有害细菌，寒冷地带的人们一般把食物放在室外一整夜，就可以有效抑制有害细菌的生长。但是炎热地区的人们不仅没有这样的气候条件，而且炎热地区很容易滋生各种病原体和寄生虫。通过长期研究后，研究人员终于得出结论，辣椒具有天然杀菌作用——当人们摄入辛辣食物后，体内温度急剧上升，这样就可以抑制食物中的有害细菌的繁殖并杀死有害细菌。⑥辣椒原来生长在中南美洲的热带地区。很早的时候美洲人就开始食用辣椒。辣椒能传遍全球还要感谢哥伦布。这位探险家在发现美洲大陆之后碰到了这种特殊的食物，并把它带回了欧洲，辣椒由此传遍世界各地。辣椒于明末传入中国，距今约400年了。这种洋辛香料很快红遍中国，进入到人们的日常饮食中。威力无比的辣椒带来的无疑是一场饮食革命，似乎任何其它传统辛香料都无法与之抗衡。16.根据第①段括号中的拼音，在“

A ）一般的学者。20 多年以前，我因为采访的需要，曾与其中古怪透顶的几位有过来往。②公认“最怪的教授”( B ）叫陶愚川，他也是当时该校学术地位最高的教授。其实，大家说他学术地位高也是估摸着说，因为除在北师大任教的同学毛礼锐之外，陶先生与学术界同仁从无联系，甚至跟他本校、本系的同事也不往来，平时大概三天都不说一句话。③我认识他的时候，他已经73 岁了 ，每天穿一身灰不溜秋的衣服，独行于图书馆、食堂、宿舍之间，不跟任何人废话。路遇的师生都恭敬地看着他，但没人敢冒昧地上前跟他搭话。事实上，在我为了走近陶先生而采访的十多位该校教师中，声称自己曾经有幸跟他说过话的，只有一个人。④陶先生早年曾经留学于日本早稻田大学和美国密歇根大学，获教育硕士学位。1949 年前曾任国立湖南师范大学和中山大学教授，还曾任大夏大学（现华东师范大学）教育系主任。自20 世纪50 年代来到曲阜师范大学，几乎没教过一天专业课，多半时间在外文系教英语，但他一直没有中断自己的专业研究。“文革”（C）前一段时间，他辞职回了浙江农村老家，仍然数次去杭州图书馆查资料，还用小学生作业本写出了几卷手稿，计9 卷300 万字。当时谁也不把这个古怪老头儿费尽心血写成的手稿当回事，随手就给丢了，他竟然从第一页开始重写，令人称赞。直到20 世纪80 年代中期，他的煌煌巨著《中国教育史比较研究》 面世，震动了教育史学界，获得全国教育科学优秀成果奖。⑤他是全校工资最高的，但每月除了留下几十元生活费之外，其余的全部交给学校党委，包括专著出版后的稿费。上交没有任何动机，拒绝也没有任何可能。⑥比陶愚川教授更为古怪的，曲阜师范大学还有一位叫庄上峰教授。⑦据说，这位庄先生与陶差不多是同期的留美生，后来也与陶差不多同期在外文系教书。其父是清朝翰林，曾在孔府做清客，实际上给末代衍圣公孔德成当私塾先生。所以庄上峰从小生活在孔府，跟孔氏直系后裔们一起玩大。⑧跟陶先生不同，陶先生对“窗外事”既不关心也不议论，而庄先生却非常关心。他曾预言“林彪要完”(D）。难道书生就一定不明世事？人们感叹——庄先生真是神人！⑨庄先生述而不作，不曾有学术专著流传。难道庄先生不学无术吗？但让人大吃一惊的是，他去世后，整理其遗物的人赫然发现了一部长篇小说的手稿，名“雷霆时代’，极端写实地描述了上个世纪30 年代他在山东大学时他的同事们的生活——闻一多、梁实秋、老舍、游国恩等教授们的轶事，稍加揣度全部能对上号。因为庄先生明了世事，所以太写实了，出版社不敢原样刊出，删掉了三分之二，剩下的也就意思不大了。⑩与陶、庄相比，书法家包备五教授就一点称不上“怪”了。本校的老先生们都说“包先生的字太好了’，但他只是教书，从不参加各级书协的任何活动，没进过专业圈子。⑾有一年，山东省政协主席托学校领导向他要字，被包先生一口回绝了。他跟学校领导说：“领导的话有时说完就说完了，你们不用太认真。他要是真喜欢我的字，还会再开口的，到那时再说。”但有一个包先生不认识的学校勤杂工，有一天突然敲开包先生家的门，忐忑不安地说，他妻子生了急病，多亏附近一家驻军医院抢救脱离了危险，他不知该怎们感谢大夫才好，客套半天，人家提出“想要包先生一幅字”。包先生一听是帮忙治病的事，二话没说，铺纸就写。更令人称奇的是，曲阜乡下一个素不相识的农村老头儿，请同村一个在学校当临时工的青年领着上门索字，却能手到擒来。包备五不但痛痛快快地写了一幅岳飞的《 满江红》 ，而且担心他没钱好好装裱，还亲自动手给装裱起来。“他肯定是真喜欢才来要的，所以必须认真对待。”⑿有这么一群怪才栖居，使这座校园充满着“郁郁乎文哉”的气息。这是如今其它校园所不多见的。21 ．对文中4 处运用引号的作用理解有误的一项是 ( 3 分）A 、否定讽刺 B、着重强调C 、特定称谓 D、引用话语22 ．不改变句意，将第（8）、（9 ）段中的画线句改成陈述句，分别为； ( 4
