If the value-added tax was done away with, it would act as a ______ to consumption. A．progression B．prime C．stimulus D．stabilityWhentheAmericaneconomywasrunningfulltilt
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 is special about this economic downturn in Seattle
A、All sectors have entered recession at the same time.
B、The lay-off workers have found jobs elsewhere.
C、The OldEconomy is hit harder than other economies.
D、The low employment rate will last longer than in Oregon.在等差数列{an}中，已知a4＋a7十a10＋a13＝20，则S16的值为()．

{{B}}Passage One{{/B}}The word "paramount" (Paragraph 4) may be replaced by ______.A．vital
The situation inAsia shows how power has shifted from individual governments to the markets. In theory, governments are free to set their own economic policies; in practice, they must conform to a global economic model or risk being penalized by the markets.
Adjusting to this new "economic order" is proving difficult, in the developed world, and in particular theEuropean Union, globalization is facing widespread public resistance.Critics complain that, without the protection of trade barriers, jobs are being lost to workers in poorer countries, and wages for employees in rich countries are falling. Opponents in theEuropean Union point to the effects that globalization has had in the U.S. andBritain. In those countries, wages are stagnant--except for a few privileged--and taxes and welfare benefits have been reduced to help companies compete with industries in the developing worlD、
Those in favor of globalization accuse their critics of being shortsighted protectionists. They claim that a more integrated global economy will ultimately benefit everyone because it will enable countries to specialize in those areas where they perform best.Developing countries, with their higher populations and lower wages, will concentrate on labor-intensive industries. The richer countries, on the other hand, will diversify into high-tech industries, where high productivity and specialist knowledge are paramount. The effect of this will be to improve productivity in all countries, leading to higher living standards. The free movement of capital will also help poorer countries develop so that they can play a full and active role in the world economy.
But how close are we to a truly global economy For those in favor of globalization, probably too close.But in terms of real economic integration, there are still many problems to be solveD、A、global economy would mean complete freedom of movement of goods and services, capital, and labor. Yet, even ignoring the tariffs and other restrictions still in place, cross-border trade remains tiny as compared with the volume of goods and services traded within countries; foreign investment is also extremely small, amounting to little more than five percent of the developed world’s domestic investments.
But what is really holding globalization back is the lack of labor mobility. Labor markets remain overwhelmingly national, even in areas like theEuropean Union, where citizens can live and work in anyEU country. The main reasons for this are language and cultural barriers; the lack of internationally recognized qualifications; and, in some cases, strict immigration controls.
B．more important
C．less important
D．similarOneofthequestionsthatiscomingintofocusas
One of the questions that is coming into focus as we face growing scarcity of resources of many kinds in the world is how to divide limited resources among countries. In the international development community, the conventional wisdom has been that the 2 billion people living in poor countries could never expect to reach the standard of living that most of us in NorthAmerica enjoy, simply because the world does not contain enough iron ore, protein, petroleum, and so on.At the same time, we in the United States have continued to pursue super affluence as though there were no limits on how much we could consume. We make up 6 percent of the world’s people; yet we consume one-third of the world’s resources.
As long as the resources we consumed each year came primarily from within our own boundaries, this was largely an internal matter.But as our resources come more and more from the outside world, "outsiders" are going to have some say over the rate at which and terms under which we consume. We will no longer be able to think in terms of "our" resources and "their" resources, but only of common resources.
AsAmericans consuming such a disproportionate share of the world’s resources, we have to question whether or not we can continue our pursuit of super affluence in a world of scarcity. We are now reaching the point where we must carefully examine’ the presumed link between our level of well-being and the level of material goods consumeD、If you have only one crust of bread and get another crust of bread, your well-being is greatly enhanceD、But if you have a loaf of bread, then an additional crust of bread doesn’t make that much difference. In the eyes of most of the world today,Americans have their loaf of bread and are asking for still more. People elsewhere are beginning to ask why. This is the question we’re going to have to answer, whether we’re trying to persuade countries to step up their exports of oil to us or trying to convince them that we ought to be permitted to maintain our share of the world fish catch.
The prospect of a scarcity of, and competition for, the world’s resources requires that we reexamine the way in which we relate to the rest of the worlD、It means we find ways of cutting back on resource consumption that is dependent on the resources and cooperation of other countries. We cannot expect people in these countries to concern themselves with our worsening energy and food shortages unless we demonstrate some concern for the hunger, illiteracy and disease that are diminishing life for them.
The writer gives the example of bread to show that ______.
A、the United States has been much richer than any other countries
B、the United States has acquired more than what it has contributed
C、the United States has been too greedy in its pursuit of super affluence
D、the United States is more capable of pursuing affluence than other countriesTheinventionofbothlabor-savingtoolsandto

A、Lesotho’s fast-growing textile industry depends almost entirely onChinese investment in factories to make clothes for sale in the United States. The region also wants more access toAmerica’s markets for fruit, beef and other agricultural goods.
American interest lies mainly in SouthAfrica, by far the largest economy in the region. Services account for 60% of its GDP, and it increasingly dominates the rest ofAfrica in banking, information technology, telecom, retail’ and other areas. Just asBritish banks, such asBarclays, have moved theirAfrican headquarters to SouthAfrica over the past year,American investors see the country as a platform to the rest of the continent.
Agreeing investment rules and resolving differences on intellectual property rights are the most urgent issues.American drug firms want to be part of the fast expansion in SouthAfrica of production of anti-retroviral drugs, used againstAIDS.By 2007 SouthAfrica alone expects 1.2m patients to take the drugs daily. The country might be the world’s biggest exporter of anti-AIDS drugs within a few years. Striking a bilateral deal now should makeAmerican investments easier.
But Mr. Zoellick’s greater concern is for multilateral trade talks that stalled inCancun, Mexico, in September.AlecErwin, his SouthAfrican counterpart, helped to organize the G20 group of poor and middle-income countries that opposed jointAmerican-EU proposals there; he is widely tipped to take over as head of the World Trade Organization late next year, and would be a useful ally.
So Mr. Zoellick is trying to charm hisAfrican partner by agreeing to drop support for most of a group of issues (known as "Singapore" issues) that jammed up the talks atCancun, and were opposed by poor countries; he says he also favors abolishing export subsidies inAmerica--though only if Japan and theEU agree to do the same. That would pleaseAfrican exporters who say such subsidies destroy markets for their goods.
Mr. Zoellick’s efforts to make more friends may be paying off.Even thoughAmerica has treatedAfrica very shabbily on trade in the past, Mr.Erwin hints it is easier doing business withAmerica than withEurope or Japan.

American drug makers want to get a share in the anti-AIDS drug production in SouthAfrica in that ______.
A、the U.S. domestic anti-AIDS drug market is shrinking quickly
