第2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.
