What’s more, the market share taken by American car brands is on the upward trend, from 10% to nearly 15%.Three reasons, in my opinion, can account for the changes in car market in these two years. First, the rise of Chinese cars is of little surprise as we have seen Chinese enterprises’ commitment to developing self-owned technologies, which not only free them from potential risks, but also bring about long-term benefit. Second, Japanese cars, which used to be highly praised for their outstanding quality and superior stability, is now reeling from a crisis of confidence. Last, the improvement of American cars’ performancemust be attributed to the smart marketing strategy employed by American sellers. They launched a lot of marketing campaigns designed specially for Chinese market, which won them applaud as well as benefit.第5页In order to maintain the good momentum of development, domestic cars should on one hand stick to their self-independent policy, and on the other, learn some experiences from Japanese car’s failures and Americans’ success.。

Mark your answers on ANSWER SHEET 1. (40 points)Text 1Ruth Simmons joined Goldman Sachs' board as an outside director in January 2000; a year later she became president of Brown University. For the rest of the decade she apparently managed both roles without attracting much criticism. But by the end of 2009 Mrs. Simmons was under fire for having sat on Goldman's compensation committee; how could she have let those enormous bonus payouts pass unremarked? By February the next year Mrs. Simmons had left the board. The position was just taking up too much time, she said.Outside directors are supposed to serve as helpful, yet less biased, advisers on a firm's board. Having made their wealth and their reputations elsewhere, they presumably have enough independence to disagree with the chief executive's proposals. If the sky, and the share price, is falling, outside directors should be able to give advice based on having weathered their own crises.The researchers from Ohio University used a database that covered more than 10,000 firms and more than 64,000 different directors between 1989 and 2004. Then they simply checked which directors stayed from one proxy statement to the next. The most likely reason for departing a board was age, so the researchers concentrated on those "surprise" disappearances by directors under the age of 70. They found that after a surprise departure, the probability that the company will subsequently have to restate earnings increases by nearly 20%. The likelihood of being named in a federal class-action lawsuit also increases, and the stock is likely to perform worse. The effect tended to be larger for larger firms. Although a correlation between them leaving and subsequent bad performance at the firm is suggestive, it does not mean that such directors are always jumpingoff a sinking ship. Often they "trade up," leaving riskier, smaller firms for larger and more stable firms.But the researches believe that outside directors have an easier time of avoiding a blow to their reputations if they leave a firm before bad news break, even if a review of history shows that they were on the board at the time any wrongdoing occurred. Firms who want to keep their outside directors through tough times may have to create incentives. Otherwise outside directors will follow the example of Ms. Simmons, once again very popular on campus.21. According to Paragraph 1, Ms. Simmons was criticized for __________________.[A] gaining excessive profits[B] failing to fulfill her duty[C] refusing to make compromises[D] leaving the board in tough times22. We learn from Paragraph 2 that outside directors are supposed to be __________________.[A] generous investors[B] unbiased executives[C] share price forecasters[D] independent advisers23. According to the researchers from Ohio University, after an outside director' s surprisedeparture, the firm is likely to __________________.[A] become more stable[B] report increased earnings[C] do less well in the stock market[D] perform worse in lawsuits24. It can be inferred from the last paragraph that outside directors __________________.[A] may stay for the attractive offers from the firm[B] have often had records of wrongdoings in the firm[C] are accustomed to stress -free work in the firm[D] will decline incentives from the firm25. The author' s attitude toward the role of outside directors is __________________.[A] permissive [B] positive[C] scornful [D] criticalText 2Whatever happened to the death of newspapers? A year ago the end seemed near. The recession threatened to remove the advertising and readers that had not already fled to the internet. Newspapers like the San Francisco Chronicle were chronicling their own doom. America's Federal Trade Commission launched a round of talks about how to save newspapers. Should they become charitable corporations? Should the state subsidize them? It will hold another meeting soon. But the discussions now seem out of date.In much of the world there is little sign of crisis. German and Brazilian papers have shrugged off the recession. Even American newspapers, which inhabit the most troubled comer of the global industry, have not only survived but often returned to profit. Not the 20% profit margins that wereroutine a few years ago, but profit all the same.It has not been much fun. Many papers stayed afloat by pushing journalists overboard. The American Society of News Editors reckons that 13,500 newsroom jobs have gone since 2007. Readers are paying more for slimmer products. Some papers even had the nerve to refuse delivery to distant suburbs. Yet these desperate measures have proved the right ones and, sadly for many journalists, they can be pushed further.Newspapers are becoming more balanced businesses, with a healthier mix of revenues from readers and advertisers. American papers have long been highly unusual in their reliance on ads. Fully 87% of their revenues came from advertising in 2008, according to the Organization for Economic Cooperation & Development (OECD). In Japan the proportion is 35%. Not surprisingly, Japanese newspapers are much more stable.The whirlwind that swept through newsrooms harmed everybody, but much of the damage has been concentrated in areas where newspapers are least distinctive. Car and film reviewers have gone. So have science and general business reporters. Foreign bureaus have been savagely cut off. Newspapers are less complete as a result. But completeness is no longer a virtue in the newspaper business.26. By saying "Newspapers like…their own doom"(Line 3, Para. 1), the author indicates that newspapers ________________.[A] neglected the sign of crisis [B] failed to get state subsidies[C] were not charitable corporations [D] were in a desperate situation27. Some newspapers refused delivery to distant suburbs probably because ________________.[A] readers threatened to pay less[B] newspapers wanted to reduce costs[C] journalists reported little about these areas[D] subscribers complained about slimmer products28. Compared with their American counterparts, Japanese newspapers are much more stable because they ________________.[A] have more sources of revenue [B] have more balanced newsrooms[C] are less dependent on advertising [D] are less affected by readership29. What can be inferred from the last paragraph about the current newspaper business?[A] Distinctiveness is an essential feature of newspapers.[B] Completeness is to blame for the failure of newspaper.[C] Foreign bureaus play a crucial role in the newspaper business.[D] Readers have lost their interest in car and film reviews.30. The most appropriate title for this text would be ________________.[A] American Newspapers: Struggling for Survival[B] American Newspapers: Gone with the wind[C] American Newspapers: A Thriving Business[D] American Newspapers: A Hopeless StoryText 3We tend to think of the decades immediately following World War 11 as a time of prosperityand growth, with soldiers returning home by the millions, going off to college on the G. I. Bill and lining up at the marriage bureaus.But when it came to their houses, it was a time of common sense and a belief that less could truly be more. During the Depression and the war, Americans had learned to live with less, and that restraint, in combination with the postwar confidence in the future, made small, efficient housing positively stylish.Economic condition was only a stimulus for the trend toward efficient living. The phrase "less is more" was actually first popularized by a German, the architect Ludwig Mies van der Rohe, who like other people associated with the Bauhaus, a school of design, emigrated to the United States before World War Ⅱand took up posts at American architecture schools. These designers came to exert enormous influence on the course of American architecture, but none more so than Mies.Mie's signature phrase means that less decoration, properly organized, has more impact than a lot. Elegance, he believed, did not derive from abundance. Like other modern architects, he employed metal, glass and laminated wood -- materials that we take for granted today but that in the1940s symbolized the future. Mies's sophisticated presentation masked the fact that the spaces he designed were small and efficient, rather than big and often empty.The apartments in the elegant towers Mies built on Chicago's Lake Shore Drive, for example, were smaller -- two-bedroom units under 1,000 square feet -- than those in their older neighbors along the city's Gold Coast. But they were popular because of their airy glass walls, the views they afforded and the elegance of the buildings' details and proportions, the architectural equivalent of the abstract art so popular at the time.The trend toward "less" was not entirely foreign. In the 1930s Frank Lloyd Wright started building more modest and efficient houses -- usually around 1,200 square feet -- than the spreading two-story ones he had designed in the 1890s and the early 20th century.The "Case Study Houses" commissioned from talented modern architects by California Arts & Architecture magazine between 1945 and 1962 were yet another homegrown influence on the "less is more" trend. Aesthetic effect came from the landscape, new materials and forthright detailing. In his Case Study House, Ralph Rapson may have mispredicted just how the mechanical revolution would impact everyday life -- few American families acquired helicopters, though most eventually got clothes dryers -- but his belief that self-sufficiency was both desirable and inevitable was widely shared.31. The postwar American housing style largely reflected the Americans' ________________.[A] prosperity and growth [B] efficiency and practicality[C] restraint and confidence [D] pride and faithfulness32. Which of the following can be inferred from Paragraph 3 about the Bauhaus?[A] It was founded by Ludwig Mies van der Rohe.[B] Its designing concept was affected by World War I1.[C] Most American architects used to be associated with it.[D] It had a great influence upon American architecture.33. Mies held that elegance of architectural design ________________.[A] was related to large space[B] was identified with emptiness[C] was not reliant on abundant decoration[D] was not associated with efficiency34. What is true about the apartments Mies built on Chicago's Lake Shore Drive?[A] They ignored details and proportions.[B] They were built with materials popular at that time.[C] They were more spacious than neighboring buildings.[D] They shared some characteristics of abstract art.35. What can we learn about the design of the "Case Study Houses" ?[A] Mechanical devices were widely used.[B] Natural scenes were taken into account.[C] Details were sacrificed for the overall effect.[D] Eco-friendly materials were employed.Text 4Will the European Union make it? The question would have sounded strange not long ago. Now even the project's greatest cheerleaders talk of a continent facing a "Bermuda triangle" of debt, population decline and lower growth.As well as those chronic problems, the EU faces an acute crisis in its economic core, the 16 countries that use the single currency. Markets have lost faith that the euro zone's economies, weaker or stronger, will one day converge thanks to the discipline of sharing a single currency, which denies uncompetitive members the quick fix of devaluation.Yet the debate about how to save Europe's single currency from disintegration is stuck. It is stuck because the euro zone's dominant powers, France and Germany, agree on the need for greater harmonization within the euro zone, but disagree about what to harmonise.Germany thinks the euro must be saved by stricter rules on borrowing, spending and competitiveness, backed by quasi-automatic sanctions for governments that do not obey. These might include threats to freeze EU funds for poorer regions and EU mega-projects, and even the suspension of a country's voting fights in EU ministerial councils. It insists that economic co-ordination should involve all 27 members of the EU club, among whom there is a small majority for free - market liberalism and economic rigour; in the inner core alone, Germany fears, a small majority favour French interference.A "southern" camp headed by France wants something different: "European economic government" within an inner core of euro-zone members. Translated, that means politicians intervening in monetary policy and a system of redistribution from richer to poorer members, via cheaper borrowing for governments through common Eurobonds or complete fiscal transfers. Finally, figures close to the French government have murmured, euro-zone members should agree to some fiscal and social harmonization: e. g. , curbing competition in corporate-tax rates or labour costs.It is too soon to write off the EU. It remains the world's largest trading block. At its best, the European project is remarkably liberal: built around a single market of 27 rich and poor countries, its internal borders are far more open to goods, capital and labour than any comparable trading area. It is an ambitious attempt to blunt the sharpest edges of globalization, and make capitalism benign.36. The EU is faced with so many problems that ________________.[A] it has more or less lost faith in markets[B] even its supporters begin to feel concerned[C] some of its member countries plan to abandon euro[D] it intends to deny the possibility of devaluation37. The debate over the EU's single currency is stuck because the dominant powers ________________.[A] are competing for the leading position[B] are busy handling their own crises[C] fail to reach an agreement on harmonization[D] disagree on the steps towards disintegration38. To solve the euro problem, Germany proposed that ________________.[A] EU funds for poor regions be increased[B] stricter regulations be imposed[C] only core members be involved in economic co-ordination[D] voting fights of the EU members be guaranteed39. The French proposal of handling the crisis implies that ________________.[A] poor countries are more likely to get funds[B] strict monetary policy will be applied to poor countries[C] loans will be readily available to rich countries[D] rich countries will basically control Eurobonds40.

(10 points) Leading doctors today weigh in on the debate over the government's role in promoting public health by demanding that ministers impose "fat taxes" on unhealthy food and introduce cigarettestyle warnings to children about the dangers of a poor diet.The demands follow comments made last week by the health secretary, Andrew Lansley, who insisted the government could not force people to make healthy choices and promised to free businesses from public health regulations.But senior medical figures want to stop fast-food outlets opening near schools, restrict advertising of products high in fat, salt or sugar, and limit sponsorship of sports events by fast-food producers such as McDonald' s.They argue that government action is necessary to curb Britain's addiction to unhealthy food and help halt spiraling rates of obesity, diabetes and heart disease. Professor Terence Stephenson, president of the Royal College of Paediatrics and Child Health, said that the consumption of unhealthy food should be seen to be just as damaging as smoking or excessive drinking."Thirty years ago, it would have been inconceivable to have imagined a ban on smoking inthe workplace or pubs, and yet that is what we have now. Are we willing to be just as courageous in respect of obesity? I would suggest that we should be," said the leader of the UK' s children' s doctors.Lansley has alarmed health campaigners by suggesting he wants industry rather than government to take the lead. He said that manufacturers of crisps and candies could play a central role in the Chang4Life campaign, the centrepiece of government efforts to boost healthy eating and fitness. He has also criticised the celebrity chef Jamie Oliver' s high-profile attempt to improve school lunches in England as an example of how "lecturing" people was not the best way to change their behaviour.Stephenson suggested potential restrictions could include banning TV advertisements for foods high in fat, salt or sugar before 9 pm and limiting them on billboards or in cinemas. "If we were really bold, we might even begin to think of high-calorie fast food in the same way as cigarettes-by setting strict limits on advertising, product placement and sponsorship of sports events," he said.Such a move could affect firms such as McDonald's, which sponsors the youth coaching scheme run by the Football Association. Fast-food chains should also stop offering "inducements" such as toys, cute animals and mobile phone credit to lure young customers, Stephenson said.Professor Dinesh Bhugra, president of the Royal College of Psychiatrists, said : "If children are taught about the impact that food has on their growth, and that some things can harm, at least information is available up front. "He also urged councils to impose "fast-food-free zones" around schools and hospitals-areas within which takeaways cannot open.A Department of Health spokesperson said:" We need to create a new vision for public health where all of society works together to get healthy and live longer. This includes creating a new 'responsibility deal' with business, built on social responsibility, not state regulation. Later this year, we will publish a white paper setting out exactly how we will achieve this. "The food industry will be alarmed that such senior doctors back such radical moves, especially the call to use some of the tough tactics that have been deployed against smoking overSection ⅢTranslation46.

(15 points)Who would have thought that, globally, the IT industry produces about the same volume of greenhouse gases as the world's airlines do -- roughly 2 percent of all CO2 emissions?Many everyday tasks take a surprising toll on the environment. A Google search can leak between 0.2 and 7.0 grams of CO2, depending on how many attempts are needed to get the "right" answer. To deliver results to its users quickly, then, Google has to maintain vast data centres around the world, packed with powerful computers. While producing large quantities of CO2, these computers emit a great deal of heat, so the centres need to be well air-conditioned, which uses even more energy.However, Google and other big tech providers monitor their efficiency closely and make improvements. Monitoring is the first step on the road to reduction, but there is much more to be done, and not just by big companies.Section ⅣWritingPart A47.

For the rest of the decade she apparently managed both roles without attracting much criticism. But by the end of 2009 Mrs. Simmons was under fire for having sat on Goldman's compensation committee; how could she have let those enormous bonus payouts pass unremarked? By February the next year Mrs. Simmons had left the board. The position was just taking up too much time, she said.Outside directors are supposed to serve as helpful, yet less biased, advisers on a firm's board. Having made their wealth and their reputations elsewhere, they presumably have enough independence to disagree with the chief executive's proposals. If the sky, and the share price, is falling, outside directors should be able to give advice based on having weathered theirown crises.The researchers from Ohio University used a database that covered more than 10,000 firms and more than 64,000 different directors between 1989 and 2004. Then they simply checked which directors stayed from one proxy statement to the next. The most likely reason for departing a board was age, so the researchers concentrated on those "surprise" disappearances by directors under the age of 70. They found that after a surprise departure, the probability that the company will subsequently have to restate earnings increases by nearly 20%. The likelihood of being named in a federal class-action lawsuit also increases, and the stock is likely to perform worse. The effect tended to be larger for larger firms. Although a correlation between them leaving and subsequent bad performance at the firm is suggestive, it does not mean that such directors are always jumping off a sinking ship. Often they "trade up," leaving riskier, smaller firmsfor larger and more stable firms.But the researches believe that outside directors have an easier time of avoiding a blow to their reputations if they leave a firm before bad news break, even if a review of history shows that they were on the board at the time any wrongdoing occurred. Firms who want to keep their outside directors through tough times may have to create incentives. Otherwise outside directors will follow the example of Ms. Simmons, once again very popular on campus.21. According to Paragraph 1, Ms. Simmons was criticized for __________________.[A] gaining excessive profits[B] failing to fulfill her duty[C] refusing to make compromises[D] leaving the board in tough times22. We learn from Paragraph 2 that outside directors are supposed to be __________________.[A] generous investors[B] unbiased executives[C] share price forecasters[D] independent advisers23. According to the researchers from Ohio University, after an outside director' s surprise departure, the firm is likely to __________________.[A] become more stable[B] report increased earnings[C] do less well in the stock market[D] perform worse in lawsuits24. It can be inferred from the last paragraph that outside directors __________________.[A] may stay for the attractive offers from the firm[B] have often had records of wrongdoings in the firm[C] are accustomed to stress -free work in the firm[D] will decline incentives from the firm25. The author' s attitude toward the role ofoutside directors is __________________.[A] permissive[B] positive[C] scornful[D] criticalText 2Whatever happened to the death of newspapers? A year ago the end seemed near. The recession threatened to remove the advertising and readers that had not already fled to the internet. Newspapers like the San Francisco Chronicle were chronicling their own doom. America's Federal Trade Commission launched a round of talks about how to save newspapers. Should they become charitable corporations? Should the state subsidize them? It will hold another meeting soon. But the discussions now seem out of date.In much of the world there is little sign of crisis. German and Brazilian papers have shrugged off the recession. Even Americannewspapers, which inhabit the most troubled comer of the global industry, have not only survived but often returned to profit. Not the 20% profit margins that were routine a few years ago, but profit all the same.It has not been much fun. Many papers stayed afloat by pushing journalists overboard. The American Society of News Editors reckons that 13,500 newsroom jobs have gone since 2007. Readers are paying more for slimmer products. Some papers even had the nerve to refuse delivery to distant suburbs. Yet these desperate measures have proved the right ones and, sadly for many journalists, they can be pushed further.Newspapers are becoming more balanced businesses, with a healthier mix of revenues from readers and advertisers. American papers have long been highly unusual in their reliance on ads. Fully 87% of their revenues came from advertising in 2008, according to the Organization for Economic Cooperation &Development (OECD). In Japan the proportion is 35%. Not surprisingly, Japanese newspapers are much more stable.The whirlwind that swept through newsrooms harmed everybody, but much of the damage has been concentrated in areas where newspapers are least distinctive. Car and film reviewers have gone. So have science and general business reporters. Foreign bureaus have been savagely cut off. Newspapers are less complete as a result. But completeness is no longer a virtue in the newspaper business.26. By saying "Newspapers like…their own doom"(Line 3, Para. 1), the author indicates that newspapers ________________.[A] neglected the sign of crisis[B] failed to get state subsidies[C] were not charitable corporations[D] were in a desperate situation27. Some newspapers refused delivery to distant suburbs probably because ________________.[A] readers threatened to pay less[B] newspapers wanted to reduce costs[C] journalists reported little about these areas[D] subscribers complained about slimmer products28. Compared with their American counterparts, Japanese newspapers are much more stable because they ________________.[A] have more sources of revenue[B] have more balanced newsrooms[C] are less dependent on advertising[D] are less affected by readership29. What can be inferred from the last paragraph about the current newspaper business?[A] Distinctiveness is an essential feature of newspapers.[B] Completeness is to blame for the failure of newspaper.[C] Foreign bureaus play a crucial role inthe newspaper business.[D] Readers have lost their interest in car and film reviews.30. The most appropriate title for this text would be ________________.[A] American Newspapers: Struggling for Survival[B] American Newspapers: Gone with the wind[C] American Newspapers: A Thriving Business[D] American Newspapers: A Hopeless StoryText 3We tend to think of the decades immediately following World War 11 as a time of prosperity and growth, with soldiers returning home by the millions, going off to college on the G. I. Bill and lining up at the marriage bureaus.But when it came to their houses, it was atime of common sense and a belief that less could truly be more. During the Depression and the war, Americans had learned to live with less, and that restraint, in combination with the postwar confidence in the future, made small, efficient housing positively stylish.Economic condition was only a stimulus for the trend toward efficient living. The phrase "less is more" was actually first popularized by a German, the architect Ludwig Mies van der Rohe, who like other people associated with the Bauhaus, a school of design, emigrated to the United States before World War Ⅱand took up posts at American architecture schools. These designers came to exert enormous influence on the course of American architecture, but none more so than Mies.Mie's signature phrase means that less decoration, properly organized, has more impact than a lot. Elegance, he believed, did not derive from abundance. Like other modern architects, he employed metal, glass andlaminated wood -- materials that we take for granted today but that in the1940s symbolized the future. Mies's sophisticated presentation masked the fact that the spaces he designed were small and efficient, rather than big and often empty.The apartments in the elegant towers Mies built on Chicago's Lake Shore Drive, for example, were smaller -- two-bedroom units under 1,000 square feet -- than those in their older neighbors along the city's Gold Coast. But they were popular because of their airy glass walls, the views they afforded and the elegance of the buildings' details and proportions, the architectural equivalent of the abstract art so popular at the time.The trend toward "less" was not entirely foreign. In the 1930s Frank Lloyd Wright started building more modest and efficient houses -- usually around 1,200 square feet -- than the spreading two-story ones he had designed in the 1890s and the early 20th century.The "Case Study Houses" commissioned from talented modern architects by California Arts & Architecture magazine between 1945 and 1962 were yet another homegrown influence on the "less is more" trend. Aesthetic effect came from the landscape, new materials and forthright detailing. In his Case Study House, Ralph Rapson may have mispredicted just how the mechanical revolution would impact everyday life -- few American families acquired helicopters, though most eventually got clothes dryers -- but his belief that self-sufficiency was both desirable and inevitable was widely shared.31. The postwar American housing style largely reflected the Americans' ________________.[A] prosperity and growth[B] efficiency and practicality[C] restraint and confidence[D] pride and faithfulness32. Which of the following can be inferred from Paragraph 3 about the Bauhaus?[A] It was founded by Ludwig Mies van der Rohe.[B] Its designing concept was affected by World War I1.[C] Most American architects used to be associated with it.[D] It had a great influence upon American architecture.33. Mies held that elegance of architectural design ________________.[A] was related to large space[B] was identified with emptiness[C] was not reliant on abundant decoration[D] was not associated with efficiency34. What is true about the apartments Mies built on Chicago's Lake Shore Drive?[A] They ignored details and proportions.[B] They were built with materials popular at that time.[C] They were more spacious than neighboring buildings.[D] They shared some characteristics ofabstract art.35. What can we learn about the design of the "Case Study Houses" ?[A] Mechanical devices were widely used.[B] Natural scenes were taken into account.[C] Details were sacrificed for the overall effect.[D] Eco-friendly materials were employed.Text 4Will the European Union make it? The question would have sounded strange not long ago. Now even the project's greatest cheerleaders talk of a continent facing a "Bermuda triangle" of debt, population decline and lower growth.As well as those chronic problems, the EU faces an acute crisis in its economic core, the 16 countries that use the single currency. Markets have lost faith that the euro zone's economies, weaker or stronger, will one day converge thanks to the discipline of sharing a singlecurrency, which denies uncompetitive members the quick fix of devaluation.Yet the debate about how to save Europe's single currency from disintegration is stuck. It is stuck because the euro zone's dominant powers, France and Germany, agree on the need for greater harmonization within the euro zone, but disagree about what to harmonise.Germany thinks the euro must be saved by stricter rules on borrowing, spending and competitiveness, backed by quasi-automatic sanctions for governments that do not obey. These might include threats to freeze EU funds for poorer regions and EU mega-projects, and even the suspension of a country's voting fights in EU ministerial councils. It insists that economic co-ordination should involve all 27 members of the EU club, among whom there is a small majority for free - market liberalism and economic rigour; in the inner core alone, Germany fears, a small majority favour French interference.A "southern" camp headed by France wants something different: "European economic government" within an inner core of euro-zone members. Translated, that means politicians intervening in monetary policy and a system of redistribution from richer to poorer members, via cheaper borrowing for governments through common Eurobonds or complete fiscal transfers. Finally, figures close to the French government have murmured, euro-zone members should agree to some fiscal and social harmonization: e.g. , curbing competition in corporate-tax rates or labour costs.It is too soon to write off the EU. It remains the world's largest trading block. At its best, the European project is remarkably liberal: built around a single market of 27 rich and poor countries, its internal borders are far more open to goods, capital and labour than any comparable trading area. It is an ambitious attempt to blunt the sharpest edges of globalization, and make capitalism benign.36. The EU is faced with so many problems that ________________.[A] it has more or less lost faith in markets[B] even its supporters begin to feel concerned[C] some of its member countries plan to abandon euro[D] it intends to deny the possibility of devaluation37. The debate over the EU's single currency is stuck because the dominant powers ________________.[A] are competing for the leading position[B] are busy handling their own crises[C] fail to reach an agreement on harmonization[D] disagree on the steps towards disintegration38. To solve the euro problem, Germany proposed that ________________.[A] EU funds for poor regions be increased[B] stricter regulations be imposed[C] only core members be involved in economic co-ordination[D] voting fights of the EU members be guaranteed39. The French proposal of handling the crisis implies that ________________.[A] poor countries are more likely to get funds[B] strict monetary policy will be applied to poor countries[C] loans will be readily available to rich countries[D] rich countries will basically control Eurobonds40.

(10 points) Leading doctors today weigh in on the debate over the government's role in promoting public health by demanding that ministers impose "fat taxes" on unhealthy food and introduce cigarettestyle warnings to children about the dangers of a poor diet.The demands follow comments made last week by the health secretary, Andrew Lansley, who insisted the government could not force people to make healthy choices and promised to free businesses from public health regulations.But senior medical figures want to stop fast-food outlets opening near schools, restrict advertising of products high in fat, salt or sugar, and limit sponsorship of sports events by fast-food producers such as McDonald' s.They argue that government action isnecessary to curb Britain's addiction to unhealthy food and help halt spiraling rates of obesity, diabetes and heart disease. Professor Terence Stephenson, president of the Royal College of Paediatrics and Child Health, said that the consumption of unhealthy food should be seen to be just as damaging as smoking or excessive drinking."Thirty years ago, it would have been inconceivable to have imagined a ban on smoking in the workplace or pubs, and yet that is what we have now. Are we willing to be just as courageous in respect of obesity? I would suggest that we should be," said the leader of the UK' s children' s doctors.Lansley has alarmed health campaigners by suggesting he wants industry rather than government to take the lead. He said that manufacturers of crisps and candies could play a central role in the Chang4Life campaign, the centrepiece of government efforts to boost healthy eating and fitness. He has also criticisedthe celebrity chef Jamie Oliver' s high-profile attempt to improve school lunches in England as an example of how "lecturing" people was not the best way to change their behaviour.Stephenson suggested potential restrictions could include banning TV advertisements for foods high in fat, salt or sugar before 9 pm and limiting them on billboards or in cinemas. "If we were really bold, we might even begin to think of high-calorie fast food in the same way as cigarettes-by setting strict limits on advertising, product placement and sponsorship of sports events," he said.Such a move could affect firms such as McDonald's, which sponsors the youth coaching scheme run by the Football Association. Fast-food chains should also stop offering "inducements" such as toys, cute animals and mobile phone credit to lure young customers, Stephenson said.Professor Dinesh Bhugra, president of the Royal College of Psychiatrists, said : "Ifchildren are taught about the impact that food has on their growth, and that some things can harm, at least information is available up front. "He also urged councils to impose "fast-food-free zones" around schools and hospitals-areas within which takeaways cannot open.A Department of Health spokesperson said:" We need to create a new vision for public health where all of society works together to get healthy and live longer. This includes creating a new 'responsibility deal' with business, built on social responsibility, not state regulation. Later this year, we will publish a white paper setting out exactly how we will achieve this. "The food industry will be alarmed that such senior doctors back such radical moves, especially the call to use some of the tough tactics that have been deployed against smoking over the last decade.[A] "fat taxes" should be imposed on fast-food producers such asMcDonald's.41．Andrew Lansley held that [B] the government should ban fast-food outlets in the neighborhood of schools.42．Terence Stephenson agreed that [C] "lecturing" was an effective way to improve school lunches in England.43．Jamie Oliver seemed to believe that [D] cigarette-style warning should be introduced to children about the dangers of a poor diet.44．Dinesh Bhugra suggested that [E] the producers of crisps and candies could contribute significantly to the Change4Life camign.45．A Department of Health spokesperson proposed that [F] parents should set good examples for their children by keeping a healthy diet at home.[G] the government should strengthen the sense of responsibility among businesses.Section ⅢTranslation46.

In his Case Study House, Ralph Rapson may have mispredicted just how the mechanical revolution would impact everyday life — few American families acquired helicopters, though most eventually got clothes dryers — but his belief that self-sufficiency was both desirable and inevitable was widely shared.31.

Text 4 The Economist(经济学家)2010年7月10日Will the European Union make it? The question would have sounded strange not longgreatest cheer ago. Now even the project’sleaders talk of a continent facing a “Bermudaof debt, population decline and lower triangle” growth.As well as those chronic problems, the EUface an acute crisis in its economic core, the 16 countries that use the single currency. Marketshave lost faith that the euro zone’s economies, weaker or stronger, will one day converge thanks to the discipline of sharing a single currency, which denies uncompetitive membersthe quick fix of devaluation.Yet the debate about how to save Europe’s single currency from disintegration is stuck. It isstuck because the euro zone’s dominant powers, France and Germany, agree on the need for greater harmonization within the euro zone, butdisagree about what to harmonies.Germany thinks the euro must be saved bystricter rules on borrow spending and competitiveness, barked by quasi-automatic sanctions for governments that do not obey. These might include threats to freeze EU fundsfor poorer regions and EU mega-projects andeven the suspension of a country’s voting rights in EU ministerial councils. It insists that economic co-ordination should involve all 27 members of the EU club, among whom there is asmall majority for free-market liberalism and economic rigour; in the inner core alone, Germany fears, a small majority favour French interference.camp headed by FrenchA “southern” wants something different: “European economicwithin an inner core of euro-zone government” members. Translated, that means politicians intervening in monetary policy and a system of redistribution from richer to poorer members,via cheaper borrowing for governments throughcommon Eurobonds or complete fiscal transfers.Finally, figures close to the France governmenthave murmured, euro-zone members shouldagree to some fiscal and social harmonization:e.g., curbing competition in corporate-tax ratesor labour costs.It is too soon to write off the EU. It remainsthe world’s largest trading block. At its best, the European project is remarkably liberal: built around a single market of 27 rich and poor countries, its internal borders are far more opento goods, capital and labour than any comparable trading area.

Mark your answers on ANSWER SHEET 1. (10 points)Leading doctors today weigh in on the debate over the government's role in promoting public health by demanding that ministers impose "fat taxes" on unhealthy food and introduce cigarette-style warnings to childrenabout the dangers of a poor diet.The demands follow comments last week by the health secretary, Andrew Lansley, who insisted the government could not force people to make healthy choices and promised to free businesses from public health regulations.But senior medical figures want to stop fast-food outlets opening near schools, restrict advertising of products high in fat, salt or sugar, and limit sponsorship of sports events by fast-food producers such as McDonald's.They argue that government action is necessary to curb Britain's addiction to unhealthy food and help halt spiralling rates of obesity, diabetes and heart disease. Professor Terence Stephenson, president of the Royal College of Paediatrics and Child Health, said that the consumption of unhealthy food should be seen to be just as damaging as smoking or binge drinking."Thirty years ago, it would have been inconceivable to have imagined a ban onsmoking in the workplace or in pubs, and yet that is what we have now. Are we willing to be just as courageous in respect of obesity? I would suggest that we should be," said the leader of the UK's children's doctors.Lansley has alarmed health campaigners by suggesting he wants industry rather than government to take the lead. He said that manufacturers of crisps and confectionery could play a central role in the Change4Life campaign, the centrepiece of government efforts to boost healthy eating and fitness. He has also criticized the celebrity chef Jamie Oliver's high-profile attempt to improve school lunches in England as an example of how "lecturing" people was not the best way to change their behaviour.Stephenson suggested potential restrictions could include banning TV advertisements for foods high in fat, salt or sugar before the 9pm watershed and limiting them on billboards or in cinemas. "If we were really bold, we might even begin to think of high-calorie fast food in thesame way as cigarettes –by setting stringentlimits on advertising, product placement and sponsorship of sports events," he said.Such a move could affect firms such as McDonald’s, which sponsors the youth coachingscheme run by the Football Association.Fast-food chains should also stop offeringsuch as toys, cute animals and “inducements” mobile phone credit to lure young customers, Stephenson said.Professor Dinesh Bhugra, president of theRoyal College of Psychiatrists, said: “If childre are taught about the impact that food has ontheir growth, and that some things can harm, atleast information is available up front.”He also urged councils to impose“fast-food-free zones” around school andhospitals-areas within which takeaways cannotopen.A Department of Health spokesperson said:“We n eed to create a new vision for publichealth where all of society works together to gethealthy and live longer. This includes creating anew ‘responsibility deal ’ with business, built on social responsibility, not state regulation. Later this year, we will publish a white paper setting out exactly how we will achieve this.”The food industry will be alarmed that suchsenior doctors back such radical moves, especially the call to use some of the tough tactics that have been deployed against smoking over the last decade.[A] “fat taxes ” shouldbe imposed on fast-foodproducerssuch as McDonald ’s.41.AndrewLansley held that [B] the governmentshould ban fast-food outletsin theneighborhood of schools.42.Terence Stephenson agreedthat [C] “lecturing ” was an effective way to improve school lunchesin England.43.Jamie Oliver seemed tobelieve that [D]cigarette-style warnings should be introduced to childrenabout the dangers of apoor diet.44.DineshBhugra suggestedthat [E] the producers of crisps and candies could contributesignificantly to theChange4Life campaign.45.A Departmentof HealthSpokesperson propsed that [F] parents should set good examples for their children by keeping ahealthy dietat home.[G] the governmentshould strengthen thesense of responsibilityamong businesses.Section Ⅲ Translation46.

A Google search can leak between 0.2 and 7.0 grams of CO2, dependingon how many attempts are needed to get theanswer. To deliver results to its users “right” quickly, then, Google has to maintain vast datacentres around the world, packed with powerful computers. While producing large quantities of CO2, these computers emit a great deal of heat, so the centres need to be well air-conditioned, which uses even more energy.However, Google and other big tech providers monitor their efficiency closely and make improvements. Monitoring is the first step on the road to reduction, but there is much moreto be done, and not just by big companies.

What’s more, the market share taken by American car brandsis on the upward trend, from 10% to nearly15%.Three reasons, in my opinion, can accountfor the changes in car market in these two years.First, the rise of Chinese cars is of little surpriseas we have seen Chinese enterprises’ commitment to developing self-owned technologies, which not only free them frompotential risks, but also bring about long-termbenefit. Second, Japanese cars, which used to behighly praised for their outstanding quality andsuperior stability, is now reeling from a crisis of confidence. Last, the improvement of Americanperformance must be attributed to thecars’ smart marketing strategy employed by American sellers. They launched a lot of marketing campaigns designed specially forChinese market, which won them applaud aswell as benefit.In order to maintain the good momentumof development, domestic cars should on onehand stick to their self-independent policy, andon the other, learn some experiences from Japanese car’s failures and Americans’ success其他客观题答案：21-25BBDAA26-30DBCBB31-35BDCDB36-40DCBAC41-45EDCFG。

As is shown in the chart, the market share of home～made automobile increased from 25% to 33%, almost an increase by 50%. In contrast, the Japanese～made automobile was on the decline from 35% to 25%, a decrease by nearly 50%. Meanwhile, the US～made automobiles remain stable in the market share.Several factors may account for the market share change of the chart. The increase in home～made automobile market share is at least closely related to the following three factors. First, in 2009, Chinese government is enhancing favorable policies to improve domestic automobile production. Meanwhile, we can see that Geely merged with Volvo in 2009, which contributes to the increase of home～made automobile market share. Another obvious evidence we can find is that the poor after～service policy of Japanese automobile toward domestic market, which irritated us Chinese consumers. And the US market policies remain unchanged in this period.In brief, the trend suggests that as long as we are improving our strategy and service, the home～made automobiles will continue to take a lion’s share of the auto～market. We look forward to that day.。

Chapter 2 课后答案
Chapter 2 课后答案The Sounds of Language1.Define each of the following terms briefly.´(1)articulator: the tongue, lips, and velum, which change the shape of the vocal tract to produce different speech sounds.(2)assimilation: a phonological process whereby a sound becomes phonetically similar (or identical) to a neighboring sound, e.g. a vowel becomes [+nasal] when followed by a [+nasal] consonant.(3)consonant: a speech sound produced by partial or complete closure of partof the vocal tract, thus obstructing the airflow and creating audible friction. Consonants are described in terms of voicing, place of articulation, and manner of articulation.(4)elision: the leaving out of a sound or sounds in speech.(5)intonation: the variation in pitch and stress which gives beat and rhythm to the tune the voice plays in ordinary speech.(6)phoneme: the abstract element of a sound, identified as being distinctive in a particular language.(7)phonetics: the study of linguistic speech sounds, how they are produced,how they are perceived, and their physical properties.(8)phonology: the study of the abstract systems underlying the sounds of language.(9)stress: the prominence given to certain sounds in speech.(10) voicing: the vibration in the larynx caused by air from the lungs passing through the vocal cords when they are partly closed; speech sounds are saidto be either voiced or voiceless.(11) voiceless: When the vocal cords are spread apart, the airstream from the lungs is not obstructed at the space between vocal cords and passes freely.The sounds produced in this way are described as voiceless sounds.(12) vowel: a speech sound produced without significant constriction of the air flowing through the oral cavity.2.Minimal pair test or substitution test.Minimal pair test or substitution test is to see whether substituting one sound foranother results in a different word. If it does, the two sounds represent different phonemes. For example, as to the English word bear, if we substitute p for b, we get the word pear, the two are different words. Then /b/ and /p/ represent different phonemes. Other examples are chunk/junk, ban/bin, bet/beat, fine/vine, side/ site, etc.3. Take the word big for example, in the word big /big/, /b/ is the onset, /i/ is thenucleus and /g/ is the coda. The difference between open syllables and closed syllablesis whether the words have codas. If there are codas, they are closed syllables,such as pig, hat and at; if not, they are open syllables, such as do, I, tea and key.4. (1)stop, consonant(2)back, rounded, vowel5. (1)voiceless / voiced(2)bilabial / labiodental(3)close / semi-open(4)stop / nasal(5)alveolar / palatal(postalveolar)(6)alveolar / dental6.

All problems from Chapter 2 of Artin’s Algebra. 1.3 If map r : N → N was a right inverse for the shift map s, then the composition sr would send 1 to 1. However, the number 1 is not in the image of s so such a right inverse is impossible. For any n ∈ N, define the map ℓn by ℓn (i) = i − 1 if i ≥ 2 and ℓn (1) = n. Then the composition ℓn s is the identity on N. Thus we have exhibited an infinite number of left inverses. 2.1 Group multiplication table for S3 = {e, (12), (13), (23), (123), (132)} with first row (resp. column) corree (12) (23) (13) (123) (132) (12) e (123) (132) (23) (13) (23) (132) e (123) (13) (12) sponding to left (resp. right-) multiplication by identity e: .

We must show that the associative law of composition, ◦, on S restricts to a law of composition on S ′ . In other words, we need to show closure: if s1 and s2 are invertible (i.e. in S ′ ), then s1 ◦ s2 is also invertible (i.e. in S ′ ). But this is clearly true since 1 −1 ′ s− 2 ◦ s1 is the inverse of s1 ◦ s2 . This law of composition on S is associative since it is associative on S . To complete the proof that subset S ′ is a group, we need to check that identity and inverses are in S ′ , and these follow quickly. 2.4 a) Yes, GLn (R) is a subgroup of GLn (C), clearly the product of two invertible matrices with real entries is an invertible matrix with real entries (implies closure ). The identity matrix has real entries, and the inverse of a matrix with real entries also has real entries. b) Yes, {−1, 1} is a subgroup of R× .

(40 points)Text 1According to Thomas Edison, most inventions are 1 percent inspiration and 99 percent perspiration. That may have been true in his day, but invention has changed radically in the past century. Today, it can be both more efficient and more frustrating, with inventors making errors such as forgetting the "ordinary skills" requirement for getting a patent and misreading established patents.Soon, these kinds of mistakes will be less likely, thanks to a new method developed by a researcher at the Fordham University School of Law in New York City.The method, known as "invention mining", is a way to find out possible inventions from huge databases of scientific information. Invention mining gives inventors many new veins to tap into - and makes it much easier to come up with new ideas.In the past, the first step of inventing something new was an exhaustive search through existing patents to make sure the proposed invention hadn't already been patented. But that traditional search couldn't effectively cover all the information needed, as it was only possible to cover a fraction of patents, university research papers, and other sources of technical information in any one search.However, invention mining can go through billions of records of technical information in one search. "Text mining is natural language processing, but invention mining is natural language processing on steroids （特效药）" says Professor Stempfle.According to his study, a successful search of one billion records using a properly formed claim will return about 3.15 million technical documents for review, and we usually only need to inspect about 150,000 of these to find a few that truly meet our needs.Invention mining can turn up scientific research and patents nobody ever knew existed. Stempfle's paper cited an example of a case study from Ford when a scientist was doing background research on fire protection systems: it found a solution that had been patented and then forgotten, dating back to an 1838 patent. "The inventors of the company that found this were excited," says Stempfle, but nobody else had ever heard of the invention. This would have been something that may not otherwise have been discovered."Invention mining gives small inventors a newfound power against large corporations," says Stempfle . "Say you're a small inventor with 20 patents, and then IBM thinks you're infringing on（侵犯） one of their patents. IBM can do a search through a million patents to find ground to say your patent is invalid. Using a tool like invention mining, you can look at the same million patents to come up with innovative ways to say the IBM patent is not reallya valid one. It really does level the playing field."21. Invention mining helps inventors to ________.A. identify and solve problems in the invention processB. establish the ordinary skills requirement for getting a patentC. read established patents with more efficiencyD. prevent scientific information from being forgotten22. Compared to the traditional search, invention mining ________.A. covers a wider range of technical informationB. is more time-consumingC. requires a larger database of scientific informationD. focuses on patents and university research papers23. What does Professor Stempfle suggest about invention mining?A. It should be used in the background research of fire protection systems.B. It should only be used by small inventors against large corporations.C. It should be improved through natural language processing.D. It should be applied to the validation of small inventors' patents.24. What can be a drawback of invention mining?A. Certain patents are prone to being misread by inventors.B. It relies heavily on existing patents.C. It doesn't cover all the technical information.D. Some 19th-century patents may have been missed.25. What is the main purpose of the text?A.

(20 points)Text 2The saying "knowledge is power" is accurate in many situations. We tend to believe that the more information we have, the better decisions we can make. However, recent research suggests that this may not always be the case. In fact, having too much information can sometimes hinder our decision-making process and lead to poorer outcomes.One reason why an excess of information may be detrimental is that it can lead to information overload. When we are faced with too much information, we may struggle to process it all efficiently. As a result, wemay overlook important details or become overwhelmed, leading to decision paralysis. In this state, it becomes difficult to make any decision at all.Furthermore, having too much information can also lead to biased decision-making. When we have a lot of information, it is natural for us to focus on the information that supports our existing beliefs or preferences, while disregarding contradictory information. This confirmation bias can limit our ability to consider alternative perspectives and make well-rounded decisions.Another issue associated with an excess of information is the potential for analysis paralysis. This occurs when we spend excessive amounts of time analyzing and comparing different options, becoming so fixated on finding the perfect choice that we fail to make a decision altogether. The fear of making a suboptimal choice can act as a barrier to action, preventing us from moving forward and potentially missing out on valuable opportunities.While information is undoubtedly valuable, it is important to strike a balance and avoid becoming overwhelmed by an excessive amount of data. Recognizing the limitations of information and being mindful of its potential effects on decision-making can help ensure more effective and efficient choices.26. What is the author's main point about information?A. It is essential for making well-rounded decisions.B. It can lead to biased decision-making.C. It can hinder the decision-making process.D. It is necessary for finding valuable opportunities.27. What is "confirmation bias"?A. Overlooking important details due to information overload.B. Struggling to process excessive amounts of information.C. Focusing on information that supports existing beliefs.D. Spending excessive time analyzing different options.28. What does the author mean by "analysis paralysis"?A. Being overwhelmed by contradictory information.B. Failing to make a decision due to fear of making a mistake.C. Considering alternative perspectives when making a choice.D. Being unable to distinguish between valuable and irrelevant information.29. According to the text, what is important when dealing with information?A. Finding the perfect choice.B. Overcoming decision paralysis.C. Recognizing the limitations of information.D.

2011考研英语(二)阅读第4篇真题WILL the European Union make it? The question would have sounded outlandis h not long ago. Now even the project’s greatest cheerleaders talk of a continent fa cing a “Bermuda triangle” of debt, demographic decline and lower growth.As well as those chronic problems, the EU faces an acute crisis in its economic core, the 16 countries that use the single currency. Markets have lost faith that th e euro zone’s economies, weaker or stronger, will one day converge thanks to the discipline of sharing a single currency, which denies uncompetitive stragglers the qui ck fix of devaluation.Yet the debate about how to save Europe’s single currency from disintegration is st uck. It is stuck because the euro zone’s dominant powers, France and Germany, ag ree on the need for greater harmonisation within the euro zone, but disagree about what to harmonise.Germany thinks the euro must be saved by stricter rules on borrowing, spendin g and competitiveness, backed by quasi-automatic sanctions for governments that st ray. These might include threats to freeze EU funds for poorer regions and EU meg a-projects, and even the suspension of a country’s voting rights in EU ministerial co uncils. It insists that economic co-ordination should involve all 27 members of the E U club, among whom there is a small majority for free-market liberalism and econo mic rigour; in the inner core alone, Germany fears, a small majority favour French dirigisme.A “southern” camp headed by France wants something different: “European eco nomic government” within an inner core of euro-zone members. Translated, that me ans politicians meddling in monetary policy and a system of redistribution from riche r to poorer members, via cheaper borrowing for governments through common Euro bonds or outright fiscal transfers. Finally, figures close to the French government ha ve murmured, euro-zone members should agree to some fiscal and social harmonisa tion: eg, curbing competition in corporate-tax rates or labour costs.It is too soon to write off the EU. It remains the world’s largest trading block. At its best, the European project is remarkably liberal: built around a single market of 27 rich and poor countries, its internal borders are far more porous to goods, ca pital and labour than any comparable trading area. It is an ambitious attempt to bl unt the sharpest edges of globalisation, and make capitalism benign.36.The EU is faced with to many problems thatA it has more or less lost faith in marketsB even its supporters begin to fell concernedC some of its member countries plan to X curoD it intends to deny the possibility of devaluation37 The X over the EU’s single currency is stuck because the X pomeryA are X for the leading positionB are busy X their own crisesCfall to reach an agreement on harmonisationD disagreement on the steps towards disintegration38 To solve the cure problem ,Gremanyproposed thatA EU funds for poor regions be XB stricter regulations be impossalC only core members be involved in ecomomic XD voting rights of the EU members be guaranteed39 The French proposal of handling the crisis implies thatA X countries are more likely to get findsB monetary policy will be applied to poor countriesC X will be readily available to rich countriesD rich countries will busically control Eurobonds40 X the future of the EU,the author seems to feelA pesaimisticB desperateCconeceiledD hopeful2011年考研英语(二)完型填空题目及参考答案"The Internet affords anonymity to its users —a boon to privacy and freedom of speech.

Our surroundings are being polluted fast and man's present efforts can not prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities and the growing use of man-made materials.What can explain and solve this problem? The fact is that pollution is caused by man -- by his desire for a modern way of life. W e make "increasing industrialization" our chief aim.So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children.There is a constant flow of people from the countryside into the cities, eager for the benefits of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.Isn't it time we stopped to ask ourselves where we are going-- and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker,"I've some good news and some bad news. The good news is that we're making rapid progress at 530 miles per hour. Thebad news is that we're lost and don't know where we're going. " The sad fact is that this becomes a true story when speaking of our modern society.In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves2011年考研英语(一)试题Section I Use of EnglishDirections:Read the following text.

Answer the questions below each text by choosing A], B], C] or D]. Mark your answers on ANSWER SHEET 1. (40 points)Text 1The decision of the New York Philharmonic to hire Alan Gilbert as its next music director has been the talk of the classical-music world ever since the sudden announcement of his appointment in 2009. For the most part, the response has been favorable, to say the least. ―Hooray! At last!‖ wrote Anthony Tommasini, a sober-sided classical-music critic.One of the reasons why the appointment came as such a surprise, however, is that Gilbert is compa ratively little known. Even Tommasini, who had advocated Gilbert’s appointment in the Times, calls him ―an unpretentious musician with no air of the formidable conductor about him.‖ As a description of the next music director of an orchestra that has hithe rto been led by musicians like Gustav Mahler and Pierre Boulez, that seems likely to have struck at least some Times readers as faint praise.For my part, I have no idea whether Gilbert is a great conductor or even a good one. To be sure, he performs an impressive variety of interesting compositions, but it is not necessary for me to visit Avery Fisher Hall, or anywhere else, to hear interesting orchestral music. All I have to do is to go to my CD shelf, or boot up my computer and download still more recorded music from iTunes.Devoted concertgoers who reply that recordings are no substitute for live performance are missing the point. For the time, attention, and money of the art-loving public, classical instrumentalists must compete not only with opera houses, dance troupes, theater companies, and museums, but also with the recorded performances of the great classical musicians of the 20th century. There recordings are cheap, available everywhere, and very often much higher in artistic quality than today’s l ive performances; moreover, they can be ―consumed‖ at a time and place of the listener’s choosing. The widespread availability of such recordings has thus brought about a crisis in the institution of the traditional classical concert.One possible response is for classical performers to program attractive new music that is not yet available on record. Gilbert’s own interest in new music has been widely noted: Alex Ross, a classical-music critic, has described him as a man who is capable of turning the Philh armonic into ―a markedly different, more vibrant organization.‖ But what will be the nature of that difference? Merely expanding the orchestra’s repertoire will not be enough. If Gilbert and the Philharmonic are to succeed, they must first change the relationship between America’s oldest orchestra and the new audience it hops to attract.21. We learn from Para.1 that Gilbert’s appointment hasA]incurred criticism.B]raised suspicion.C]received acclaim.D]aroused curiosity.22. Tommasini regards Gilbert as an artist who isA]influential.B]modest.C]respectable.D]talented.23. The author believes that the devoted concertgoersA]ignore the expenses of live performances.B]reject most kinds of recorded performances.C]exaggerate the variety of live performances.D]overestimate the value of live performances.24. According to the text, which of the following is true of recordings?A]They are often inferior to live concerts in quality.B]They are easily accessible to the general public.C]They help improve the quality of music.D]They have only covered masterpieces.25. Regarding Gilbert’s role in revitalizing the Philharmonic, the author feelsA]doubtful.B]enthusiastic.C]confident.D]puzzled.Text 2When Liam McGee departed as president of Bank of America in August, his explanation was surprisingly straight up. Rather than cloaking his exit in the usual vague excuses, he came right out and said he was leaving ―to pursue my goal of running a company.‖ Broadcasting his ambition was ―very much my decision,‖ McGee says. Within two weeks, he was talking for the first time with the board of Hartford Financial Services Group, which named him CEO and chairman on September 29.McGee says leaving without a position lined up gave him time to reflect on what kind of company he wanted to run. It also sent a clear message to the outside world about his aspirations. And McGee isn’t alone. In recent weeks the No.2 executives at Avon and American Express quit with the explanation that they were looking for a CEO post. As boards scrutinize succession plans in response to shareholder pressure, executives who don’t get the nod also may wish to move on. A turbulent business environment also has senior managers cautious of letting vague pronouncements cloud their reputations.As the first signs of recovery begin to take hold, deputy chiefs may be more willing to make the jump without a net. In the third quarter, CEO turnover was down 23% from ayear ago as nervous boards stuck with the leaders they had, according to Liberum Research. As the economy picks up, opportunities will abound for aspiring leaders.The decision to quit a senior position to look for a better one is unconventional. For years executives and headhunters have adhered to the rule that the most attractive CEO candidates are the ones who must be poached. Says Korn/Ferry senior partner Dennis Carey:‖I can’t think of a single search I’ve done where a board has not instructed me to look at sitting CE Os first.‖Those who jumped without a job haven’t always landed in top positions quickly. Ellen Marram quit as chief of Tropicana a decade age, saying she wanted to be a CEO. It was a year before she became head of a tiny Internet-based commodities exchange. Robert Willumstad left Citigroup in 2005 with ambitions to be a CEO. He finally took that post at a major financial institution three years later.Many recruiters say the old disgrace is fading for top performers. The financial crisis has made it more a cceptable to be between jobs or to leave a bad one. ―The traditional rule was it’s safer to stay where you are, but that’s been fundamentally inverted,‖ says one headhunter. ―The people who’ve been hurt the worst are those who’ve stayed too long.‖26. When McGee announced his departure, his manner can best be described as beingA]arrogant.B]frank.C]self-centered.D]impulsive.27. According to Paragraph 2, senior executives’ quitting may be spurred byA]their expectation of better financial status.B]their need to reflect on their private life.C]their strained relations with the boards.D]their pursuit of new career goals.28. The word ―poached‖ (Line 3, Paragraph 4) most probably meansA]approved of.B]attended to.C]hunted for.D]guarded against.29. It can be inferred from the last paragraph thatA]top performers used to cling to their posts.B]loyalty of top performers is getting out-dated.C]top performers care more about reputations.D]it’s safer to stick to the traditional rules.30. Which of the following is the best title for the text?A]CEOs: Where to Go?B]CEOs: All the Way Up?C]Top Managers Jump without a NetD]The Only Way Out for Top PerformersText 3The rough guide to marketing success used to be that you got what you paid for. No longer. While traditional ―paid‖ media – such as television commercials and print advertisements –still play a major role, companies today can exploit many alternative forms of media. Consumers passionate about a product may create ―owned‖ media by sending e-mail alerts about products and sales to customers registered with its Web site. The way consumers now approach the broad range of factors beyond conventional paid media.Paid and owned media are controlled by marketers promoting their own products. For earned media , such marketers act as the initiator for users’ responses. But in some cases, one marketer’s owned media become another marketer’s paid media – for instance, when an e-commerce retailer sells ad space on its Web site. We define such sold media as owned media whose traffic is so strong that other organizations place their content or e-commerce engines within that environment. This trend ,which we believe is still in its infancy, effectively began with retailers and travel providers such as airlines and hotels and will no doubt go further. Johnson & Johnson, for example, has created BabyCenter, a stand-alone media property that promotes complementary and even competitive products. Besides generating income, the presence of other marketers makes the site seem objective, gives companies opportunities to learn valuable information about the appeal of other companies’ marketing, and may help expand user traffic for all companies concerned. The same dramatic technological changes that have provided marketers with more (and more diverse) communications choices have also increased the risk that passionate consumers will voice their opinions in quicker, more visible, and much more damaging ways. Such hijacked media are the opposite of earned media: an asset or campaign becomes hostage to consumers, other stakeholders, or activists who make negative allegations about a brand or product. Members of social networks, for instance, are learning that they can hijack media to apply pressure on the businesses that originally created them.If that happens, passionate consumers would try to persuade others to boycott products, putting the reputation of the target company at risk. In such a case, the company’s response may not be sufficiently quick or thoughtful, and the learning curve has been steep. Toyota Motor, for example, alleviated some of the damage from its recall crisis earlier this year with a relatively quick and well-orchestrated social-media responsecampaign, which included efforts to engage with consumers directly on sites such as Twitter and the social-news site Digg.31.Consumers may create ―earned‖ media when they areA] obscssed with online shopping at certain Web sites.B] inspired by product-promoting e-mails sent to them.C] eager to help their friends promote quality products.D] enthusiastic about recommending their favorite products.32. According to Paragraph 2,sold media featureA] a safe business environment.B] random competition.C] strong user traffic.D] flexibility in organization.33. The author indicates in Paragraph 3 that earned mediaA] invite constant conflicts with passionate consumers.B] can be used to produce negative effects in marketing.C] may be responsible for fiercer competition.D] deserve all the negative comments about them.34. Toyota Motor’s experience is cited as an example ofA] responding effectively to hijacked media.B] persuading customers into boycotting products.C] cooperating with supportive consumers.D] taking advantage of hijacked media.35. Which of the following is the text mainly about ?A] Alternatives to conventional paid media.B] Conflict between hijacked and earned media.C] Dominance of hijacked media.D] Popularity of owned media.Text 4It’s no surprise that Jennifer Senior’s insightful, provocative magazine cover story, ―I love My Children, I Hate My Life,‖ is arousing much chatter – nothing gets people talking like the suggestion that child rearing is anything less than a completely fulfilling, life-enriching experience. Rather than concluding that children make parents either happy or miserable, Senior suggests we need to redefine happiness: instead of thinking of it as something that can be measured by moment-to-moment joy, we should consider being happy as a past-tense condition. Even though the day-to-day experience of raising kids can be soul-crushingly hard, Senior writes that ―the very things that in the moment dampen our moods can later be sources of intense gratification and delight.‖The magazine cover showing an attractive mother holding a cute baby is hardly the only Madonna-and-child image on newsstands this week. There are also stories about newly adoptive – and newly single –mom Sandra Bullock, as well as the usual ―Jennifer Aniston is preg nant‖ news. Practically every week features at least one celebrity mom, or mom-to-be, smiling on the newsstands.In a society that so persistently celebrates procreation, is it any wonder that admitting you regret having children is equivalent to admitting you support kitten-killing ? It doesn’t seem quite fair, then, to compare the regrets of parents to the regrets of the children. Unhappy parents rarely are provoked to wonder if they shouldn’t have had kids, but unhappy childless folks are bothered with the message that children are the single most important thing in the world: obviously their misery must be a direct result of the gaping baby-size holes in their lives.Of course, the image of parenthood that celebrity magazines like Us Weekly and People present is hugely unrealistic, especially when the parents are single mothers like Bullock. According to several studies concluding that parents are less happy than childless couples, single parents are the least happy of all. No shock there, considering how much work it is to raise a kid without a partner to lean on; yet to hear Sandra and Britney tell it, raising a kid on their ―own‖ (read: with round-the-clock help) is a piece of cake.It’s hard to imagine that many people are dumb enough to want children just because Reese and Angelina make it look so glamorous: most adults understand that a baby is not a haircut. But it’s interesting to wonder if the images we see every week of stress-free, happiness-enhancing parenthood aren’t in some small, subconscious way contributing to our own dissatisfactions with the actual experience, in the same way that a small part of us hoped getting ― the Rachel‖ might make us look just a little bit like Jennifer Aniston. 36.Jennifer Senior suggests in her article that raising a child can bringAtemporary delightB]enjoyment in progressC]happiness in retrospectD]lasting reward37.We learn from Paragraph 2 thatA]celebrity moms are a permanent source for gossip.B]single mothers with babies deserve greater attention.C]news about pregnant celebrities is entertaining.D]having children is highly valued by the public.38.It is suggested in Paragraph 3 that childless folksA]are constantly exposed to criticism.B]are largely ignored by the media.C]fail to fulfill their social responsibilities.D]are less likely to be satisfied with their life.39.According to Paragraph 4, the message conveyed by celebrity magazines isA]soothing.B]ambiguous.C]compensatory.D]misleading.40.Which of the following can be inferred from the last paragraph?A]Having children contributes little to the glamour of celebrity moms.B]Celebrity moms have influenced our attitude towards child rearing.C]Having children intensifies our dissatisfaction with life.D]We sometimes neglect the happiness from child rearing.Part BDirections:The following paragraph are given in a wrong order.

You can, Mr Menand points out, became a lawyer in three years and a medical doctor in four. But the regular time it takes to get a doctoral degree in the humanities is nine years. Not surprisingly, up to half of all doctoral students in English drop out before getting their degrees.B] His concern is mainly with the humanities: Literature, languages, philosophy and so on. These are disciplines that are going out of style: 22% of American college graduates now major in business compared with only 2% in history and 4% in English. However, many leading American universities want their undergraduates to have a grounding in the basic canon of ideas that every educated person should posses. But most find it difficult to agree on what a ―general education‖ should look like. At Harvard, Mr Menand notes, ―the grea t books are read because they have been read‖-they form a sort of social glue.C] Equally unsurprisingly, only about half end up with professorships for which they entered graduate school. There are simply too few posts. This is partly because universities continue to produce ever more PhDs. But fewer students want to studyhumanities subjects: English departments awarded more bachelor’s degrees in 1970-71 than they did 20 years later. Fewer students requires fewer teachers. So, at the end of a decade of theses-writing, many humanities students leave the profession to do something for which they have not been trained.D] One reason why it is hard to design and teach such courses is that they can cut across the insistence by top American universities that liberal-arts educations and professional education should be kept separate, taught in different schools. Many students experience both varieties. Although more than half of Harvard undergraduates end up in law, medicine or business, future doctors and lawyers must study a non-specialist liberal-arts degree before embarking on a professional qualification.E] Besides professionalizing the professions by this separation, top American universities have professionalised the professor. The growth in public money for academic research has speeded the process: federal research grants rose fourfold between 1960and 1990, but faculty teaching hours fell by half as research took its toll. Professionalism has turned the acquisition of a doctoral degree into a prerequisite for a successful academic career: as late as 1969a third of American professors did not possess one. But the key idea behind professionalisation, argues Mr Menand, is that ―the knowledge and skills needed for a particular specialization are transmissible b ut not transferable.‖So disciplines acquire a monopoly not just over the production of knowledge, but also over the production of the producers of knowledge.F] The key to reforming higher education, concludes Mr Menand, is to alter the way in which ―the producers of knowledge are produced.‖Otherwise, academics will continue to think dangerously alike, increasingly detached from the societies which they study, investigate and criticize.‖Academic inquiry, at least in some fields, may need to become less excl usionary and more holistic.‖Yet quite how that happens, Mr Menand dose not say. G] The subtle and intelligent little book The Marketplace of Ideas: Reform and Resistance in the American University should be read by every student thinking of applying to tak e a doctoral degree. They may then decide to go elsewhere. For something curious has been happening in American Universities, and Louis Menand, a professor of English at Harvard University, captured it skillfully.G → 41. →42. → E →43. →44. →45.Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written carefully on ANSWER SHEET 2. (10 points)With its theme that ―Mind is the master weaver,‖ creating our inner character and outer circumstances, the book As a Man Thinking by James Allen is an in-depth exploration of the central idea of self-help writing.(46) Allen’s contribution was to take an a ssumption we all share-that because we are not robots we therefore control our thoughts-and reveal its erroneous nature. Because most of us believe that mind is separate from matter, we think that thoughts can be hidden and made powerless; this allows us to think one way and act another. However, Allen believed that the unconscious mind generates as much action as the conscious mind, and (47) while we may be able to sustain the illusion of control through the conscious mind alone, in reality we are continua lly faced with a question: ―Why cannot I make myself do this or achieve that? ‖Since desire and will are damaged by the presence of thoughts that do not accord with desire, Allen concluded : ― We do not attract what we want, but what we are.‖ Achievement happens because you as a person embody the external achievement; you don’t ― get‖ success but become it. There is no gap between mind and matter.\Part of the fame of Allen’s book is its contention that ―Circumstances do not make a person, they reveal him.‖ (48) This seems a justification for neglect of those in need, and a rationalization of exploitation, of the superiority of those at the top and the inferiority of those at the bottom.This ,however, would be a knee-jerk reaction to a subtle argument. Each set of circumstances, however bad, offers a unique opportunity for growth. If circumstances always determined the life and prospects of people, then humanity would never have progressed. In fat, (49)circumstances seem to be designed to bring out the best in us and if we feel that we have been ―wronged‖ then we are unlikely to begin a conscious effort to escape from our situation .Nevertheless, as any biographer knows, a person’s early life and its conditions are often the greatest gift to an individual.T he sobering aspect of Allen’s book is that we have no one else to blame for our present condition except ourselves. (50) The upside is the possibilities contained in knowing that everything is up to us; where before we were experts in the array of limitations, now we become authorities of what is possible.Section Ⅲ WritingPart A51.

Answer the questions after each text by choosing A, B, C or D.Mark your answers on ANSWER SHEET 1. (40points)Text 1Ruth Simmons joined Goldman Sachs’s board as an outside director in January 2000: a yearlater she became president of Brown University. For the rest of the decade she apparently managed both roles without attracting much eroticism. But by the end of 2009 Ms. Simmons wasunder fire for having sat on Goldman’s compensation committee; how could she have let those enormous bonus payouts pass unremarked? By February the next year Ms. Simmons had left theboard. The position was just taking up too much time, she said.Outside directors are supposed to serve as helpful, yet less biased, advisers on a firm’s board.Having made their wealth and their reputations elsewhere, they presumably have enough independence to disagree with th e chief executive’s proposals. If the sky, and the share price isfalling, outside directors should be able to give advice based on having weathered their owncrises.The researchers from Ohio University used a database hat covered more than 10,000 firmsand more than 64,000 different directors between 1989 and 2004. Then they simply checkedwhich directors stayed from one proxy statement to the next. The most likely reason for departinga board was age, so the researchers concentrated on those “surprise” disappearances by directorsunder the age of 70. They fount that after a surprise departure, the probability that the companywill subsequently have to restate earnings increased by nearly 20%. The likelihood of beingnamed in a federal class-action lawsuit also increases, and the stock is likely to perform worse.The effect tended to be larger for larger firms. Although a correlation between them leaving and subsequent bad performance at the firm is suggestive, it does not mean that such directors arealwa ys jumping off a sinking ship. Often they “trade up.” Leaving riskier, smaller firms for larger and more stable firms.But the researchers believe that outside directors have an easier time of avoiding a blow to their reputations if they leave a firm before bad news breaks, even if a review of history shows they were on the board at the time any wrongdoing occurred. Firms who want to keep their outside directors through tough times may have to create incentives. Otherwise outside directors will follow the example of Ms. Simmons, once again very popular on campus.21. According to Paragraph 1, Ms. Simmons was criticized for .[A]gaining excessive profits[B]failing to fulfill her duty[C]refusing to make compromises[D]leaving the board in tough times22. We learn from Paragraph 2 that outside directors are supposed to be .[A]generous investors[B]unbiased executives[C]share price forecasters[D]independent advisers23. According to the researchers from Ohio University after an outside direc tor’s surprise departure, the firm is likely to .[A]become more stable[B]report increased earnings[C]do less well in the stock market[D]perform worse in lawsuits24. It can be inferred from the last paragraph that outside directors .[A]may stay for the attractive offers from the firm[B]have often had records of wrongdoings in the firm[C]are accustomed to stress-free work in the firm[D]will decline incentives from the firm25. The author’s attitude toward the role of outside directors is .[A]permissive[B]positive[C]scornful[D]criticalText 2Whatever happened to the death of newspaper? A year ago the end seemed near. The recession threatened to remove the advertising and readers that had not already fled to the internet. New spapers like the San Francisco Chronicle were chronicling their own doom. America’s Federal Trade commission launched a round of talks about how to save newspapers. Should they become charitable corporations? Should the state subsidize them ? It will hold another meeting soon. But the discussions now seem out of date.In much of the world there is the sign of crisis. German and Brazilian papers have shrugged off the recession. Even American newspapers, which inhabit the most troubled come of the global industry, have not only survived but often returned to profit. Not the 20% profit margins that were routine a few years ago, but profit all the same.It has not been much fun. Many papers stayed afloat by pushing journalists overboard. The American Society of News Editors reckons that 13,500 newsroom jobs have gone since 2007. Readers are paying more for slimmer products. Some papers even had the nerve to refuse delivery to distant suburbs. Yet these desperate measures have proved the right ones and, sadly for many journalists, they can be pushed further.Newspapers are becoming more balanced businesses, with a healthier mix of revenues from readers and advertisers. American papers have long been highly unusual in their reliance on ads. Fully 87% of their revenues came from advertising in 2008, according to the Organization for Economic Cooperation & Development (OECD). In Japan the proportion is 35%. Not surprisingly, Japanese newspapers are much more stable.The whirlwind that swept through newsrooms harmed everybody, but much of the damage has been concentrated in areas where newspaper are least distinctive. Car and film reviewers have gone. So have science and general business reporters. Foreign bureaus have been savagely cut off. Newspapers are less complete as a result. But completeness is no longer a virtue in the newspaper business.26. By saying “Newspapers like … their own doom” (Lines 3-4, Para. 1), the author indicates that newspaper .[A]neglected the sign of crisis[B]failed to get state subsidies[C]were not charitable corporations[D]were in a desperate situation27. Some newspapers refused delivery to distant suburbs probably because .[A]readers threatened to pay less[B]newspapers wanted to reduce costs[C]journalists reported little about these areas[D]subscribers complained about slimmer products28. Compared with their American counterparts, Japanese newspapers are much more stable because they .[A]have more sources of revenue[B]have more balanced newsrooms[C]are less dependent on advertising[D]are less affected by readership29. What can be inferred from the last paragraph about the current newspaper business?[A]Distinctiveness is an essential feature of newspapers.[B]Completeness is to blame for the failure of newspaper.[C]Foreign bureaus play a crucial role in the newspaper business.[D]Readers have lost their interest in car and film reviews.30. The most appropriate title for this text would be .[A]American Newspapers: Struggling for Survival[B]American Newspapers: Gone with the Wind[C]American Newspapers: A Thriving Business[D]American Newspapers: A Hopeless StoryText 3We tend to think of the decades immediately following World War II as a time of prosperityand growth, with soldiers returning home by the millions, going off to college on the G. I. Bill and lining up at the marriage bureaus.But when it came to their houses, it was a time of common sense and a belief that less could truly be more. During the Depression and the war, Americans had learned to live with less, and that restraint, in combination with the postwar confidence in the future, made small, efficient housing positively stylish.Economic condition was only a stimulus for the trend toward efficient living. The phrase “less is more” was actually first popularized by a German, the architect Ludwig Mies van der Rohe, who like other people associated with the Bauhaus, a school of design, emigrated to the United States before World War IIand took up posts at American architecture schools. These designers came to exert enormous influence on the course of American architecture, but none more so that Mies.Mies’s signature phrase means that less decoration, properly organized, has more impact that a lot. Elegance, he believed, did not derive from abundance. Like other modern architects, he employed metal, glass and laminated wood-materials that we take for granted today buy that in the 1940s symbolized the future. Mies’s sophisticated presentation masked the fact that the spaces he designed were small and efficient, rather than big and often empty.The apartments in the elegant towers Mies built on Chicago’s Lake Shore Drive, for example, were smaller-two-bedroom units under 1,000 square feet-than those in their older neighbors along the city’s Gold Coast. But they were popular because of their airy glass walls, the views they afforded and the elegance of the buildings’ details and proportions, the architectural equivalent of the abstract art so popular at the time.The trend toward “less” was not entirely foreign. In the 1930s Frank Lloyd Wright started building more modest and efficient houses-usually around 1,200 square feet-than the spreading two-story ones he had designed in the 1890s and the early 20th century.The “Case Study Houses” commissioned from talented modern architects by California Arts & Architecture magazine between 1945 and 1962 were yet another homegrown influence on the “less is more” trend. Aesthetic effect came from the landscape, new materials and forthright detailing. In his Case Study House, Ralph everyday life - few American families acquired helicopters, though most eventually got clothes dryers - but his belief that self-sufficiency was both desirable and inevitable was widely shared.31. The postwar American h ousing style largely reflected the Americans’.[A]prosperity and growth[B]efficiency and practicality[C]restraint and confidence[D]pride and faithfulness32. Which of the following can be inferred from Paragraph 3 about Bauhaus?[A]It was founded by Ludwig Mies van der Rohe.[B]Its designing concept was affected by World War II.[C]Most American architects used to be associated with it.[D]It had a great influence upon American architecture.33. Mies held that elegance of architectural design .[A]was related to large space[B]was identified with emptiness[C]was not reliant on abundant decoration[D]was not associated with efficiency34. What is true about the apartments Mies building Chicago’s Lake Shore Drive?[A]They ignored details and proportions.[B]They were built with materials popular at that time.[C]They were more spacious than neighboring buildings.[D]They shared some characteristics of abstract art.35. What can we learn about the design of the “Case Study House”?[A]Mechanical devices were widely used.[B]Natural scenes were taken into consideration[C]Details were sacrificed for the overall effect.[D]Eco-friendly materials were employed.Text 4Will the European Union make it? The question would have sounded strange not long ago. Now even the project’s greatest cheerleaders talk of a continent facing a “Bermuda triangle” of debt, population decline and lower growth.As well as those chronic problems, the EU face an acute crisis in its economic core, the 16 countries tha t use the single currency. Markets have lost faith that the euro zone’s economies, weaker or stronger, will one day converge thanks to the discipline of sharing a single currency, which denies uncompetitive members the quick fix of devaluation.Yet the deb ate about how to save Europe’s single currency from disintegration is stuck. It is stuck because the euro zone’s dominant powers, France and Germany, agree on the need for greater harmonization within the euro zone, but disagree about what to harmonies.Germany thinks the euro must be saved by stricter rules on borrow spending and competitiveness, barked by quasi-automatic sanctions for governments that do not obey. These might include threats to freeze EU funds for poorer regions and EU mega-projects and even the suspension of a country’s voting rights in EU ministerial councils. It insists that economic co-ordination should involve all 27 members of the EU club, among whom there is a small majority for free-market liberalism and economic rigour; in the inner core alone, Germany fears, a small majority favour French interference.A “southern” camp headed by French wants something different: ”European economic government” within an inner core of euro-zone members. Translated, that means politicians intervening in monetary policy and a system of redistribution from richer to poorer members, via cheaper borrowing for governments through common Eurobonds or complete fiscal transfers. Finally, figures close to the France government have murmured, curo-zone members should agree to some fiscal and social harmonization: e.g., curbing competition in corporate-tax rates or labour costs.It is too soon to write off the EU. It remains the world’s largest trading block. At its best, the European project is remarkably liberal: built around a single market of 27 rich and poor countries, its internal borders are far more open to goods, capital and labour than any comparable trading area. It is an ambitious attempt to blunt the sharpest edges of globalization, and make capitalism benign.36. The EU is faced with so many problems that .[A] it has more or less lost faith in markets[B] even its supporters begin to feel concerned[C] some of its member countries plan to abandon euro[D] it intends to deny the possibility of devaluation37. The debate over the EU’s single currency is stuck because the dominant powers.[A] are competing for the leading position[B] are busy handling their own crises[C] fail to reach an agreement on harmonization[D] disagree on the steps towards disintegration38. To solve the euro problem ,Germany proposed that .[A] EU funds for poor regions be increased[B] stricter regulations be imposed[C] only core members be involved in economic co-ordination[D] voting rights of the EU members be guaranteed39. The French proposal of handling the crisis implies that __ __.［A］poor countries are more likely to get funds［B］strict monetary policy will be applied to poor countries［C］loans will be readily available to rich countries［D］rich countries will basically control Eurobonds40.

A Google search can leak between 0.2 and 7.0 grams of CO2 depending on how many attempts are needed to get the “right” answer. To deliver results to its users quickly, then, Google has to maintain vast data centres round the world, packed with powerful computers. While producing large quantities of CO2, these computers emit a great deal of heat, so the centres need to be well air-conditioned, which uses even more energy.However, Google and other big tech providers monitor their efficiency closely and make improvements. Monitoring is the first step on the road to reduction, but there is much to be done, and not just by big companies.Section IV WritingPart A47 Directions:Suppose your cousin Li Ming has just been admitted to a university.

2.5通常使用逻辑运算代替数值运算是非常方便的。
例如，逻辑运算AND将两个位组合的方法同乘法运算一样。
哪一种逻辑运算和两个位的加法几乎相同？这样情况下会导致什么错误发生？
逻辑运算OR和两个位的加法几乎相同。
问题在于多个bit的乘或加运算无法用AND或OR运算替代，因为逻辑运算没有相应的进位机制。
2.6 假设一台数码相机的存储容量是256MB，如果每个像素需要3个字节的存储空间，而且一张照片包括每行1024个像素和每列1024个像素，那么这台数码相机可以存放多少张照片？
每张照片所需空间为：1024*1024*3=3MB
则256M可存照片数为：256MB/3MB≈85张。
2.14某测试程序在一个40 MHz处理器上运行，其目标代码有100 000条指令，由如下各类指令及其时钟周期计数混合组成，试确定这个程序的有效CPI、MIPS的值和执行时间。
CPI=(45000/100000)*1+(32000/100000)*2+(15000/100000)*2+(8000/100000) *2=0.45*1+0.32*2+0.15*2+0.08*2=1.55
MIPS=40/1.55=25.8
执行时间T=(100000*1.55)*(1/(40*10∧6) )=15.5/4*10∧（-3）= 3.875*10∧（-3） s= 3.875ms
2.15 假设一条指令的执行过程分为“取指令”、“分析”和“执行”三段，每一段的时间分别为∆t,2∆t和3∆t。
在下列各种情况下，分别写出连续执行n条指令所需要的时间表达式。
（1）顺序执行方式
T= (∆t+2∆t+3∆t)*n=6n∆t
（2）仅“取指令”和“执行”重叠
当“取指令”和“执行”重叠时，指令的执行过程如图所示：
第1条指令执行完的时间：t1=∆t+2∆t+3∆t=6∆t
第2条指令执行完的时间：t2= t1+5∆t=6∆t+5∆t*1
第3条指令执行完的时间：t3= t2+5∆t=6∆t+5∆t*2
…
第n条指令执行完的时间：tn= tn-1+∆t=6∆t+5∆t*（n-1）=(1+5n)∆t
（3）“取指令”、“分析”和“执行”重叠
当“取指令”、“分析”和“执行”重叠时，指令的执行过程如图所示：
第1条指令执行完的时间：t1=∆t+2∆t+3∆t=6∆t
第2条指令执行完的时间：t2= t1+3∆t=6∆t+3∆t*1
第3条指令执行完的时间：t3= t2+3∆t=6∆t+3∆t*2
…
第n条指令执行完的时间：tn= tn-1+3∆t=6∆t+3∆t*（n-1）=(3+3n)∆t。
