| 第3题：When theAmerican economy was running full tilt two years ago, few places were as breathlessly delighted as Seattle. Its port was thronged with ships bringing goods fromAsi A、TheBoeingCompany could barely keep up with demand for its airliners. Microsoft was hiring hordes of software engineers.After each rain shower, another Internet millionaire sprang up. Here was a city that had it all--OldEconomy, NewEconomy, Not-Yet-InventedEconomy. Now it has all gone sour. The past 12 months have been a non-stop succession of disappointments.Boeing’s headquarters decamped toChicago. The Internet economy popped alike a balloon in a nail factory, taking with it once promising local ventures such as Homegrocer.com and leaving can’t-possibly-miss companies such as drugstore.com barely hanging on.And an already troubledBoeing was hit even harder after September 11th both by a steep drop in airliner orders and by losing a $ 200 billion Joint Strike Fighter contract to Lockheed Martin. Washington State, battered by what is happening in Seattle, now has the highest unemployment rate in the United States--6.6% compared with 5.4% in the country as a whole. Right behind it is next-door Oregon, another former boom state, with 6.5% of its workforce out of a job, the country’s second worst figure. In Oregon, manufacturing’s collapse has caused the loss of nearly 30,000 jobs in a year, those hit range from Freightliner, a maker of heavy lorries, to high-tech companies such as Intel and Fujitsu. What makes the current plunge so painful is that every part of the economy seems to have stepped into an open manhole at the same time. Three years ago, whenBoeing began to remove more than 20,000 people thatBoeing expects to lay off by the middle of 2002 have to compete with unemployed workers not just from the high-tech industry but from construction work and even the retail sector. Portland now has more jobless than the other parts of Oregon: the opposite of how things were years ago. Even worse, the Pacific north west’s downturn, as well as being deeper than the rest of the country, may also last longer. One reason for fearing this isBoeing’s continuing woes. NowadaysBoeing accounts for less than 5% of employment in the Seattle area, down from 9% two decades ago.But it remains the foundation on which the rest is built. Its network of suppliers and subcontractors gives it a far stronger multiplier effect than, say, Microsoft, which is more an island of prosperity than a center of weB、The chances are thatBoeing will not really bounce back until the assumed revival in air travel persuades airline companies to start buying plenty of aircraft again.And that may not be until 2003. What does the passage imply about "Homegrocer.com" and "drugstore.com" A、They are neither promising companies. B、They are affiliated to large companies. C、They are dealing in medical products. D、They are also affected by the economic crisis. |

| 第5题：The day was star-crossed: Friday the 13th in the month of October, on the eve of the second looming anniversary of a devastating market crash. "I’m telling you, psychology is really funny. People get crazy in situations like that," said portfolio strategistElaine Garzarelli. Last week Friday the 13th lived up to its frightful reputation.After drifting lower at a sleepy pace for most of the day, theDow Jones industrial average abruptly lurched into a hair-raising sky dive in the final hour of trading. TheBushAdministration moved swiftly to avert any sense of crisis after the market closeD、Declared Treasury Secretary NicholasBrady: "It’s important to recognize that today’s stock market decline doesn’t signal any fundamental change in the condition of the economy. The economy remains well balanced, and the outlook is for continued moderate growth."But MassachusettsDemocratEdward Markey, who chairs a House subcommittee on telecommunications and finance, vowed to hold hearings this week on the stock market slide. Said he: "This is the second heart attack. My hope is that before we have the inevitable third heart attack, we pay attention to these problems." Experts found no shortage of culprits to blame for the latest shipwreck. A、series of downbeat realizations converged on Friday, ranging from signs of a new burst of inflation to sagging corporate profits to troubles in the junk-bond market that has fueled major takeovers. The singular event that shook investors was the faltering of a $6.75 billion labor management buyout of UAL, the parent company of UnitedAirlines, the second largest U. S. carrier. On one point most thoughtful Wall Streeters agreed: the market had reached such dizzying heights that a correction of some sort seemed almost inevitable. Propelled by favorable economic news and a wave of multibillion-dollar takeovers, stocks had soared more than 1,000 points since the 1987 crash.But by lastAugust some Wall streeters were clearly worrieD、 The heaviest blow to the market came Friday afternoon. In a three-paragraph statement, UAL said a labor-management group headed byChairman Stephen Wolf had failed to get enough financing to acquire UniteD、Several banks had apparently balked at the deal, which was to be partly financed through junk bonds. The take-over group said it would submit a revised bid "in the near term,’ but the announcement stunned investors who had come to view the United deal as the latest sure thing in the 1980s buyout binge. Said JohnDowney, a trader at theChicagoBoard OptionsExchange: "The airline stocks have looked like attractive takeover targets.But with the United deal in trouble, everyone started to wonder what other deals might not go through.\ How do the public feel about the current economic situation [A] Trustful. [B] PanickeD、 [C]Carefree. [D]ConfuseD、 |

| 第6题：It is just one example of the growing concern over the increasing power consumption and environmental impact of computers. A、study found that the power consumption of data centers doubled between 2000 and 2005, and now accounts for 1.2% ofAmerican electricity consumption, though other estimates put the figure at 4%.Companies now spend as much as 10% of their technology budgets on energy, says Rakesh Kumar of Gartner, a consultancy. Power consumption has increased because of the rise of the internet, of course, but also because of way in which computers have historically been designed: to maximize performance at all costs.Between 1996 and 2006, the number of servers in use went from 6 million to 28 million and the average power consumption of each server grew from 150 watts to 400 watts.But things are now starting to change and the computer industry has been seized with enthusiasm for "green computing". |

| 第7题：Another month, another dismal set of job figures.America pulled out of its last economic recession way back in November 2001, yet the country’s "jobs recession" finished only last autumn, when 2.7 million jobs had been lost since the start of the slowdown. Now, though economic growth has bounced back, new jobs refuse to do the same in this, the third year of recovery. In February, a mere 21,000 jobs were created, according to the official payroll survey, at a time when GeorgeBush’s economists forecast 2.6 million new jobs for 2004 mounting alarm at the White House, and increased calls for protection against what a growing number ofAmericans see as the root of most ills: the "outsourcing" of jobs to places likeChina and Indi A、Last week the Senate approved a bill that forbids the outsourcing of government contracts--a curious case of a government guaranteeing not to deliver value-for-money to taxpayers.American anxiety over the economy appears to have tipped over into paranoia and self-delusion. Too strong Not really.As TheEconomist has recently argued--though in the face of many angry readers--the jobs lost are mainly a cyclical affair, not a structural one. They must also be set against the 24 million new jobs created during the 1990s.Certainly, the slow pace of job-creation today is without precedent, but so were the conditions that conspired to slow a booming economy at the beginning of the decade. A、stock market bubble burst, and rampant business investment slumpeD、Then, when the economy was down, terrorist attacks were followed by a spate of scandals that undermined public trust in the way companies were run. These acted as powerful headwinds and, in the face of them, the last recession was remarkably milD、By the same token, the recovery is mild, too. Still, in the next year or so, today’s high productivity growth will start to translate into more jobs. Whether that is in time for Mr.Bush is another matter. As for outsourcing, it is implausible now, as Lawrence Katz at Harvard University argues, to think that outsourcing has profoundly changed the structure of theAmerican economy over just the past three or four years.After all, outsourcing was in full swing--both in manufacturing and in services--throughout the job-creating 1990s. Government statisticians reckon that outsourced jobs are responsible for well under 1% of those signed up as unemployeD、And the jobs lost to outsourcing pale in comparison with the number of jobs lost and created each month at home. The bill approved last week shows that theAmericans ______. A、have been carried away with their fear of the gloomy employment prospect B、will be able to deliver more money than value to the taxpayers C、decide that they would lay more emphasis on value than money D、are becoming very curious about the government’s outsourcing contracts |
