| 第5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 |

| 第8题：People don’t want to buy information online. WhyBecause they don’t have to. No more than that because they’re used to not paying for it. That’s the conventional wisdom. Slate, Microsoft’s online politics-and-culture magazine, is an oft-cited example of the failed attempts to charge a fee for access to content. So far, for most publishers, it hasn’t workeD、 But nothing on the Web is a done deal. In September graphics-soft-ware powerhouseAdobe announced new applications that integrate commerce into downloading books and articles online, with Simon & Schuster,Barnes and Noble, and Salon. corn among its high-profile partners. Some analysts put the market for digitized publishing at more than $100 billion. Of course, if the Internet can generate that kind of money—some might say almost any kind of money—people want in.And this couldn’t come at a better time. Newspaper and magazine writers in particular are increasingly frustrated by their publishers, which post their writings online but frequently don’t pay them extrA、 So here’s the good news: Fathrain. com, the third biggest book-seller on the Net—afterAmazon. com andBarnesandnoble. corn—is now doing just what the publishing industry that made it a success fears., it’s offering a secure way to pay for downloadable manuscripts online. Fatbrain calls it offshoot eMatter. With it, the company’s executives have the radical notion of ousting publishers from the book-selling business altogether by giving writers 50% of each and every sale (To reel in authors, eMatter is running a 100% royalty promotion until the end of the year. ) Suggested prices to consumers range from a minimum $ 2 to $ 20, depending on the size of the book to downloaD、 "This will change publishing forever!"Chris MaeAskill, co-founder and chief executive of Fatbrain, declares with the bravado of an interior decorator. "With eBay, anybody could sell antiques. Now anybody can be publisheD、" There’s been no shortage of authors wanting in. Within a few weeks, according to the company, some 2,000 writers signed on to publish their works. Some of this is technical stuff—Fatbrain got where it is by specializing in technical books—but there are some well-known writers likeCatherine Lanigan, author of Romancing the Stone, who has put her out-of-print books and a new novella on the site.Another popular draw is RichardBach, who agreed to post a 23-page short story to the site. Not everyone thinks downloadable documents are the biggest thing in publishing since Oprah’sBookCluB、"I think it will appeal to sellers more than buyers," says Michael May, a digitalcommerce analyst at JupiterCommunications, which released a report that cast doubt on the market’s potential. "A、lot of people are going to publish gibberish. The challenge is to ensure the quality of the work. " Blaine Mathieu, an analyst at Gartner Group’sDataquest, says, "Most people who want digital content want it immediately, I don’t know if this model would satisfy their immediate neeD、Even authors may not find that Web distribution of their works is going to bring them a pot of golD、For one thing, it could undermine sales rather than enhance them. For another, anybody could e-mail downloaded copies of manuscripts around town or around the world over the Net without the writer’s ever seeing a proverbial dime. " Softlock. com,Authentica and Fatbrain are trying to head this problem off by developing encryption padlocks that would allow only one hard drive to receive and print the manuscripts. For now, the problem persists. Which of the following is NOT a reason for some people’s belief that e-publishers will not succeed [A] Readers often want immediate digital content. [B]Authors usually do not believe they’ll earn money on Net. [C] The quality of the books on Net is hard to manage. [D]Books that sell well usually do not turn to Net |
