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8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 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.

第10题：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 countries
