共用题干第二篇The American IndustryA history of long and effortless success can be a dreadful handicap,but if properly handled,it may become a driving force.When the United States entered just such a glowing period after the end of the Second World War,it had a market eight times larger than any competitor,giving its industries unparalleled economies of scale.Its scientists were the world's best,its workers the most skilled.America and Americans were prosperous beyond the dreams of the Europeans and Asians whose economies the war had destroyed.It was inevitable that this primacy should have narrowed as other countries grew richer. Just as inevitably,the retreat from predominance proved painful.By the mid-1980s Americans had found themselves at a loss over their fading industrial competitiveness.Some huge American industries, such as consumer electronics,had shrunk or vanished in the face of foreign competition.By 1987 there was only one American television maker left,Zenith.(Now there is none:Zenith was bought by South Korea's LG Electronics in July.)Foreign-made cars and textiles were sweeping into the domestic market. America's machine-tool industry was on the ropes.For a while it looked as though the making of semiconductors,which America had which sat at the heart of the new computer age, was going to be the next casualty.All of this caused a crisis of confidence.Americans stopped taking prosperity for granted.They began to believe that their way of doing business was failing,and that their incomes would therefore shortly begin to fall as well. The mid-1980s brought one inquiry after another into the causes of America's industrial decline.Their sometimes sensational findings were filled with warnings about the growing competition from overseas.How things have changed!In 1995 the United States can look back on five years of solid growth while Japan has been struggling. Few Americans attribute this solely to such obvious causes as a devalued dollar or the turning of the business cycle.Self-doubt has yielded to blind pride."American industry has changed its structure,has gone on a diet,has learnt to be more quick-witted,"according to Richard Cavanagh,executive dean of Harvard's Kennedy School of Government,"It makes me proud to be an American just to see how our businesses are improving their productivity,"says Stephen Moore of the Cato Institute,a think-tank in Washington,DC.And William Sahlman of the Harvard Business School believes that people will look back on this period as"a golden age of business management in the United States."The author seems to believe the revival of the U.S.economy in the 1990s can be attributed to the______.A:turning of the business cycleB:restructuring of industryC:improved business managementD:success in education

Text 2 A deal is a deal-except,apparently,when Entergy is involved.The company,a major energy supplier in New England,provoked justified outrage in Vermont last week when it announced it was reneging on a longstanding commitment to abide by the strict nuclear regulations.Instead,the company has done precisely what it had long promised it would not challenge the constitutionality of Vermont’s rules in the federal court,as part of a desperate effort to keep its Vermont Yankee nuclear power plant running.It’s a stunning move.The conflict has been surfacing since 2002,when the corporation bought Vermont’s only nuclear power plant,an aging reactor in Vernon.As a condition of receiving state approval for the sale,the company agreed to seek permission from state regulators to operate past 2012.In 2006,the state went a step further,requiring that any extension of the plant’s license be subject to Vermont legislature’s approval.Then,too,the company went along.Either Entergy never really intended to live by those commitments,or it simply didn’t foresee what would happen next.A string of accidents,including the partial collapse of a cooling tower in 207 and the discovery of an underground pipe system leakage,raised serious questions about both Vermont Yankee’s safety and Entergy’s management–especially after the company made misleading statements about the pipe.Enraged by Entergy’s behavior,the Vermont Senate voted 26 to 4 last year against allowing an extension.Now the company is suddenly claiming that the 2002 agreement is invalid because of the 2006 legislation,and that only the federal government has regulatory power over nuclear issues.The legal issues in the case are obscure:whereas the Supreme Court has ruled that states do have some regulatory authority over nuclear power,legal scholars say that Vermont case will offer a precedent-setting test of how far those powers extend.Certainly,there are valid concerns about the patchwork regulations that could result if every state sets its own rules.But had Entergy kept its word,that debate would be beside the point.The company seems to have concluded that its reputation in Vermont is already so damaged that it has noting left to lose by going to war with the state.But there should be consequences.Permission to run a nuclear plant is a poblic trust.Entergy runs 11 other reactors in the United States,including Pilgrim Nuclear station in Plymouth.Pledging to run Pilgrim safely,the company has applied for federal permission to keep it open for another 20 years.But as the Nuclear Regulatory Commission（NRC）reviews the company’s application,it should keep it mind what promises from Entergy are worth.30.It can be inferred from the last paragraph thatA.Entergy’s business elsewhere might be affected.B.the authority of the NRC will be defied.C.Entergy will withdraw its Plymouth application.D.Vermont’s reputation might be damaged.

单选题Since 1960, the fast-growing town of Hotstone, Arizona, has drawn water from the Gray River, which feeds Lake Mudfish. If the town’s water use continues to grow at its present rate, in about 20 years the water level of Lake Mudfish will inevitably decrease to the point that it can no longer support its biologically fragile population of fish.

问答题Practice 4 In the first year or so of Web business, most of the action has revolved around efforts to tap the consumer market. More recently, as the Web proved to be more than a fashion, companies have started to buy and sell products and services with one another. Such business-to-business sales make sense because businesspeople typically know what product they’re looking for. Nonetheless, many companies still hesitate to use the Web because of doubts about its reliability. “Businesses need to feel they can trust the pathway between them and the supplier,” says senior analyst Blane Erwin of Forrester Research.

问答题Passage 14Questions 8—12 ● Read the article below about GE. ● Choose the best sentence from the opposite page to fill each of the gaps. ● For each gap (8—12), mark one letter (A—G) on your Answer Sheet. ● Do not use any letter more than once. ● There is an example at the beginning, (0).A slipping crown For decades America’s General Electric (GE) has worn its AAA credit rating as a badge of pride. The company has also used it to mint money in its financial-services business, GE Capital. No longer (0)______. That added insult to the injury that GE has already suffered. Last year the outfit generated a profit of $8.6 billion or almost 48％ of GE’s total earnings. By exploiting its AAA rating, GE Capital was able to raise capital cheaply and then deploy it to fund everything from commercial-property and home loans to credit-card lending and insurance. (8)______. Announcing its decision to downgrade the business, SP predicted rising credit losses in coming months in several areas of GE Capital’s portfolio. Although GE’s demotion from AAA was bad news, it triggered a rise in the firm’s shares, which had recently been trading at about the same price as one of the light bulbs that the company makes. (9)______. They may also have taken comfort from the agency’s conclusion that GE’s industrial businesses should continue to pump oodles of cash, in spite of the global downturn. Yet some financial analysts are still fretting that GE Capital’s portfolio may contain more nasty surprises. (10)______. They also wonder out loud whether Moody’s, another rating agency, will take a more pessimistic view of GE’s prospects when it finishes a review of the AAA rating that it still assigns to the firm. Next week GE plans to hold an in-depth briefing on the state of the assets in GE Capital’s portfolio, which will help to dispel the cloud still hanging over the business. It has also been telling anyone who will listen that it doesn’t expect this week’s downgrade to have a significant impact on its business, though it does plan to keep shrinking GE Capital’s activities so that the unit represents no more than 30％ of total profit. (11)______. GE is sitting on $48 billion of cash and has already raised over 90％ of its long-term debt needs for this year—no mean feat in a dire credit market. The company also plans to slash its dividend from the second half of 2009, which it reckons to conserve an additional $9 billion a year on an ongoing basis. (12)______.. In his annual letter to shareholders published recently, Mr. Immelt admitted that GE’S reputation had been “tarnished”. A. This has made some of the company’s small investors apoplectic; they have grown used to juicy dividend payments. B. Jeff Immelt, GE’s CEO, has said that the overall company will continue to manage itself like a AAA-rated firm, notably by keeping plenty of liquidity to hand. C. Resolving lingering doubts over GE Capital quickly will be essential if one of America’s most iconic companies is to regain its shine. D. They point out that the business does not mark many of its assets to their market price—a practice that has blown huge holes in the finances of many big banks. E. No doubt investors were relieved that SP didn’t make an even deeper cut in the company’s rating. F. But the chaos triggered by the credit crunch has taken the shine off GE’s cash machine, which has seen some of its property and other loans turn sour. G. SP stripped the company and its financial arm of their top-notch ratings, downgrading them to AA-plus.
