24、 been 10 years. In those awful days right after 9/11, I asked my colleague, Dave Barry, if he thought he would ever write jokes again. He was then the humor columnist for the Miami Herald. “For the last week,” he told me, “I havent even tried to write anything funny, and for a while I thought maybe
25、I never would, or should.”He had it; we all had itthat feeling of being stuck, unable to find your way back to the life you had lived before. I wrote 10 columns in a row about what I had seen, the planes crashing, the lives lost. Finally, I had to force myself to write a column about something that
26、was not terror. That last one column. Then I went right back to what was now normal.That was a decade ago. Todays terrors become tomorrows memories. News becomes history. And I find myself remembering how I used to kill ants when I was a child. The thing that truck me was that they always came back.
27、 Even if you destroy their world a hundred times, they build it a hundred and one times.There is something of that in people. It may be one of the best things about us. We always fight the cruel things in life, bury our dead, rebuild, and find a way to move forward. We did it when fire burned down C
28、hicago, after the earthquake in San Francisco, and after the floods in New Orleans. And we did it on September 11. It is true that we have changed in ways that are not all good. We are at war on three fronts. We are running a strange prison on Cuba. The government may not tell you why. Osama bin Lad
29、en is dead. Experts tell us the terror group he led is weakened. However, terrorism remains alive in American political thought, which is becoming more extreme. There is reason to be worried about these changes. But I am still grateful that we moved away from the 9/11 nightmare at all. 51. Which phr
30、ase can be used to describe Dave Barrys feeling just after 9/11?A. sad but confident B. frightened but hopefulC. heartbroken and hopeless D. unable to care or focus52. From Paragraph 3, we can conclude that _. A. no one ever feels safe anymore B. the author was so shaken that he stopped writing comp
31、letely C. there was no terrorism in America before 9/11D. for some time Americans found it difficult to think about anything except terror53 With the example of ants, the author aims to show that _. A. he misses his happy childhoodB. people can rebuild and recover, just like antsC. he is sorry that
32、he killed the ants D. rebuilding is more important than sadness54. According to the last part of the article, the authors main point is that _.A. people should look on the bright sideB. terrorism has influenced the government too muchC. no changes are ever completely goodD. terrorism will continue t
33、o existBCyberspace, the connections between computers in different places, considered as a real place where information, messages and pictures exist, mirrors the real world in many ways. People ask for information, play games, and share hobbies. Others buy and sell products. Still others look for fr
34、iendship, or even love.Unlike the real world, however, your knowledge about a person is limited to words on a computer screen. Identity and appearance mean very little in cyberspace. Rather, a persons thoughtsor at least the thoughts they typeare what really count. So even the shyest person can beco
35、me a chat room star. Usually, this “faceless” communication doesnt create problems. Identity doesnt really matter when youre in a chat room discussing politics or hobbies. In fact, this emphasis(强调,重视) on the ideas themselves makes the Internet a great place for exciting conversation. Where else can
36、 so many people come together to chat? But some Internet users want more than just someone to chat with. Theyre looking for serious love relationships. Is cyberspace a good place to find love? That answer depends on whom you ask. Some of these relationships actually succeed. Others fail miserably. S
37、upporters of online relationships state that the Internet allows couples to get to know each other intellectually first. Personal appearance doesnt get in the way. But critics of online relationships argue that no one can truly know another person in cyberspace. Why? Because the Internet gives users
38、 a lot of control over how others view them. Internet users can carefully craft their words to fit whatever image they want to give. And they dont have to worry about what their “nonverbal” (非言语交际的)communication is doing for their image. In a sense, theyre not really themselves. All of this may be f
39、ine if the relationship stays in cyberspace. But not knowing a person is a big problem in a love relationship. With so many unknowns, its easy to let ones imagination “fill in the blanks.” This inevitably(不可避免地) leads to disappointment when couples meet in person. How someone imagines an online frie
40、nd is often quite more different than the real person. So, before looking for love in cyberspace, remember the advice of Internet pioneer Clifford Stoll: “Life in the real world is far richer than anything youll find on a computer screen.”55. According to the passage, chatting in the cyberspace _. A
41、.needs people to be rich in knowledge B. puts emphasis on peoples thoughtsC. allows people to discuss politics secretlyD. stresses more about peoples identity56. People who are against online love think _. A. it is hard to protect the others identityB. the faceless communication is excitingC. what i
42、s said online is under control of the InternetD. one may not show the real self in cyberspace57. By saying “With so many unknowns, its easy to let ones imagination fill in the blanks”, the writer means that _.A. the Internet makes it easy for people to imagine how others view themB. the Internet all
43、ows people to get more information about their loved ones C. people usually get to know each other by chance through the InternetD. people may be disappointed when they meet in person 58. We can infer from the last paragraph that Clifford_.A. demands to develop the computer system B. supports to loo
44、k for love in the real life C. encourages people to enjoy modern lifeD. believes it hopeless to find love onlineCYouve probably heard of Marco Polo, but how much do you actually know about him and his amazing journey? Marco was the original travel writer, whose trade contacts with Asia changed Europ
45、e, opening it up to new ideas and cultures.Marco Polo was born in the Venetian Republic around 1254. At the time, Venice was one of the most powerful trading cities in the world, and was ruled as an independent city state. Marcos mother died when he was young, so he was brought up by his aunt and un
46、cle. When Marco was born, his brother (Maffeo) and father (Niccolo), who were successful businessmen, were away on a trading voyage. They didnt get back until Marco was about 15.In 1271, Niccolo and Maffeo set off again for Asia, this time taking Marco with them. On a previous journey theyd met Kubl
47、ai Khan (the Yuan Dynasty), and they were eager to establish trade links between Kublais empire and Venice. The Polos sailed across the Mediterranean to Acre (now in northern Israel). Then, they traveled by camel to the port of Hormuz in the Persian Gulf. Their plan was to sail to China but they cou
48、ldnt find any good boats. So, they continued the journey overland, finally meeting Kublai Khan at his summer palace in Xanadu, about 275 km north of modern Beijing. Marco was now probably 21 years old. The journey had taken over three years.The Polos had learnt a great deal about the world during th
49、eir travels and so Kublai employed Marco as a government official. This gave Marco the opportunity to travel around much of Kublais empire in China. In fact, Kublai found the Polos so useful that he was unwilling to let them return home. However, in 1292, the Polos eventually left, sailing from Chin
50、a and ending up in Hormuz again. The journey was extremely dangerous: of the 600 travelers who set off, only 18 arrived in Hormuz, including all three of the Polo family. The Polos finally returned to Venice in 1295, twenty-four years after setting off. They had traveled 24,000 km. By this time Veni
51、ce was at war with Genoa, its trade competitor. Unfortunately for Marco, he was caught by the Genoese and put into prison. However, he used his time as a prisoner to write a book about his familys travels: II Milione (known as The Travels of Marco Polo in English). It was the first book to tell Euro
52、peans about China and the East. No original copy survives, but there are several versions of it. Marcos writings influenced many other travelers, including Christopher Columbus, who carried a copy of II Milione with him on his voyage in search of India.After his release from prison in 1299, Marco re
53、joined his father and uncle in Venice. The family were now even wealthier than before thanks to the many treasures theyd brought back from the East. Marco supported many more trading journeys but never left the city again. He died in 1324 and was buried in the church of San Lorenzo in Venice. 59. Wh
54、at is the correct order of what Marco Polo has done?a. met Kublai Khan in Xanadub. sailed across the Mediterraneanc. sailed for Hormuzd. left Venice for Asiae. went to Hormuz by camelf. employed as a government official in ChinaA. b-c-d-f-a-c B. d-b-e-a-f-c C. d-c-b-a-f-e D. b-d-c-f-a-e60.

Which of the following is true according to the passage?A. .Marco was born into a very poor family but died in wealth.B. Soon after
56、his mothers death, Marco was raised by his fatherC. Marco spent about six years on the way to China and back to Venice.D. Marco died at the age of 70 in the church of San Lorenzo in Venice.62. The passage is most probably taken from _. A. a newspaperB. a history bookC. a travelers guideD. a geograph
57、y book DAs anyone who has tried to lose weight knows, realistic goal-setting generally produces the best results. Thats partially because it appears people who set realistic goals actually work more efficiently, and exert more effort, to achieve those goals. What are far less understood by scientist
58、s, however, are the potentially harmful effects of goal-setting. There has been surprisingly little research on how the practice may have contributed to the current economic crisis and unethical （不道德）behavior in general.“Goals are widely used and promoted as having really beneficial effects. And yet
59、, the same motivation that can push people to exert more effort in a constructive way could also motivate people to be more likely to engage in unethical behaviors,” says Maurice Schweitzer, an associate professor of operations and information management at Penns Wharton School. His paper, titled “G
60、oals Gone Wild: The Systematic Side Effects of Over-Prescribing Goal Setting,” appears in the February issue of the Academy of Management Perspectives. “It turns out theres no economic benefit to just having a goal-you just get a psychological benefit and thats quite motivating in itself,” Schweitze
61、r says. “But in many cases, goals have economic rewards that make them more powerful.”A prime example Schweitzer and his colleagues give is the 2004 closing down of energy-trading titan（巨头）Enron, where managers used financial rewards to motivate salesmen to meet specific sales goals. The problem, Sc
62、hweitzer says, is the actual trades were not earning money. Other studies have shown that pressing employees with unrealistic goals can force them to lie, cheat or steal. Such was the case, Schweitzer says, in the early 1990s when Sears imposed a sales target on its auto repair staff. It resulted in
63、 employees overcharging for work and completing unnecessary repairs on a companywide basis.Schweitzer admits his research run against a very large body of literature that praises the many benefits of goal-setting. Edwin A. Locke, from the University of Maryland, College Park, and Gary P. Latham, fro
64、m the University of Toronto, write: “Goal setting is not going away. Organizations cannot develop without being focused on their desired results any more than an individual can develop without goals to provide a sense of purpose.”The debate is likely to be popular on in future papers, and the practi
65、ce of setting goals no doubt will continue. For now, though, the lesson seems to be to put more thought into setting goals. “They really do help to coordinate and motivate people. My idea would be to combine that with careful observation, a strong organizational culture, and make sure the goals that
66、 you use are going to be constructive and not significantly harm the organization,” Schweitzer says.63. What message does the author try to get across about goal-setting?A. The goal increase peoples work efficiency. B. Its role has been largely underestimated.C. The goal most people set are unrealis
67、tic. D. Its negative effects have long been ignored. 64. What does Maurice Schweitzer want to show by giving the example of Enron?A. Financial rewards ensure companies meet specific sales goals.B. Businesses are less likely to succeed without setting realistic goals.C. Goals with financial rewards h
68、ave strong motivational power. D. Setting realistic goals can turn a failing business into success.65. How did Sears goal-setting affect its employees?A. They were forced to work more hours to increase their sales.B. They turned to unethical practice to meet their sales target.C. They improved their
69、 customer service on a companywide basis.D. They competed with one another to attract more customers.第二卷 (非选择题，共40分)第五部分：任务型阅读（共10小题；每小题1分，满分10分）Chinas Tianhe-1 has a computing speed of 2,507 trillion（万亿）calculations a second, making it the fastest computer in the world.

89、 in the picture, an old man and his grandson are taking a walk in the street with masks covering their mouths. As the haze is becoming heavier and heavier, they find it hard to see the buildings and trees around them clearly.What the picture tries to convey is that air pollution is quite severe in C
90、hina. Many factors account for this phenomenon. In the first place, vehicles letting off large quantities of poisonous gases are a major source of air pollution. Furthermore, factories that release a great deal of smoke are also responsible for the poor air quality. Besides, burning materials like c
91、oal or oil for homes and offices is another major contributor to air pollution.Personally, to better the air quality, the government and the common citizens should make joint efforts. Riding and walking are wise options for public travels. Meanwhile, effective laws are supposed to be made to guarantee good air quality. Only when the whole society takes an active part in the battle against air pollution can we get out of the haze and live under the bright blue sky again!
