单选题 Passage 4 Most critical plot points in Harry Potter and the Sorcerer's Stone came from J.K. Rowling's imagination, but Flamel and his powerful pebble were legendary long before Harry went to Hogwarts. The 14th century alchemist created the philosopher's stone (called "sorcerer's" in U.S. editions of Potter), with which he turned mercury to gold and gained eternal life. But Flamel's tale - like his stone and his science - was no more real than a magic. The philosopher's stone was the key to alchemy, the medieval predecessor to chemistry that aimed to cure all illnesses, make the elixir of life, and transmute base metals into gold. The last made perfect sense at the time. The Aristotelian theory of elements stated that all things consisted of fire, air, water, and earth. So a little shift in one metal's composition could create gold. Hamel was renowned as an alchemical success. In 1382, after 25 years of studying an ancient book by "Abraham the Jew," he is said to have produced the philosopher's stone. His texts, notably a deconstruction of the "Abraham" work, were standard reading for aspiring scientists like Isaac Newtori. Many alchemists believed Flamel faked his 1418 death and that of his wife. Rumored sightings in the 18th century placed them at the Paris Opera. As late as 1816, there were reports of people searching Flamel's former house for secrets of the stone. Contemporary historians say a Nicolas Flamel did live in Paris in the 1300s and endowed many churches and hospitals with his wealth. But he was no alchemist. "He got his money in pedestr/an ways - his wife's earlier marriages, real-estate speculation," says Lawrence Principe, author of The Aspiring Adept. Anachronisms, style of language, and the lack of earlier copies indicate that none of "his" writings originated prior to the 1500s. "This sort of thing happens in alchemy," says Bill Newman, author of alchemical history Gehennical Fire. When an alchemist couldn't back up his ideas, he might publish them in the guise of a "lost" work. Flamel's wealth made a good candidate for alchemical identity theft. Flamel writings and sightings faded with alchemy's prestige. And the closest anyone's come to the philosopher's stone is Rowling. In her hands, it has yielded not just gold but eternal (shelf) life as well.

单选题If you intend using humor in your talk to make people smile, you must know how to identify shared experiences and problems. Your humor must be relevant to the audience and should help to show them that you are one of them or that you understand their situation and are in sympathy with their point of view. Depending on whom you are addressing, the problems will be different. If you are talking to a group of managers, you may refer to the disorganized methods of their secretaries; alternatively if you are addressing secretaries, you may want to comment on their disorganized bosses. Here is an example, which I heard at a nurses" convention, of a story which works well because the audience all shared the same view of doctors. A man arrives in heaven and is being shown around by St. Peter. He sees wonderful accommodations, beautiful gardens, sunny weather, and so on. Everyone is very peaceful, polite and friendly until, waiting in a line for lunch, the new arrival is suddenly pushed aside by a man in a white coat, who rushes to the head of the line, grabs his food and stamps over to a table by himself. "Who is that?" the new arrival asked St. Peter. "Oh, that"s God," came the reply, "but sometimes he thinks he"s a doctor." If you are part of the group which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it"ll be appropriate for you to make a passing remark about the inedible canteen food or the chairman"s notorious bad taste in ties. With other audiences you mustn"t attempt to cut in with humor as they will resent an outsider making disparaging remarks about their canteen or their chairman. You will be on safer ground if you stick to scapegoats like the Post Office or the telephone system. If you feel awkward being humorous, you must practice so that it becomes more natural. Include a few casual and apparently off-the-cuff remarks which you can deliver in a relaxed and unforced manner. Often it"s the delivery which causes the audience to smile, so speak slowly and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark. Look for the humor. It often comes from the unexpected—a twist on a familiar quote "If at first you don"t succeed, give up" or a play on words or on a situation. Search for exaggerations and understatements. Look at your talk and pick out a few words or sentences which you can turn about and inject with humor.

单选题A great deal of attention is being paid today to the so-called digital divide—the division of the world into the info(information)rich and the info poor. And that divide does exist today. My wife and I lectured about this looming danger twenty years ago. What was less visible then, however, were the new, positive forces that work against the digital divide. There are reasons to be optimistic. There are technological reasons to hope the digital divide will narrow. As the Internet becomes more and more commercialized, it is in the interest of business to universalize access — after all, the more people online, the more potential customers there are. More and more governments, afraid their countries will be left behind, want to spread Internet access. Within the next decade or two, one to two billion people on the planet will be netted together. As a result, I now believe the digital divide will narrow rather than widen in the years ahead. And that is very good news because the Internet may well be the most powerful tool for combating world poverty that we've ever had. Of course, the use of the Internet isn't the only way to defeat poverty. And the Internet is not the only tool we have. But it has enormous potential. To take advantage of this tool, some impoverished countries will have to get over their outdated anti-colonial prejudices with respect to foreign investment. Countries that still think foreign investment is an invasion of their sovereignty might well study the history of infrastructure(the basic structural foundations of a society)in the United States. When the United States built its industrial infrastructure, it didn't have the capital to do so. And that is why America's Second Wave infrastructure — including roads, harbors, highways, ports and so on — were built with foreign investment. The English, the Germans, the Dutch and the French were investing in Britain's former colony. They financed them. Immigrant Americans built them. Guess who owns them now? The Americans. I believe the same thing would be true in places like Brazil or anywhere else for that matter. The more foreign capital you have helping you build your Third Wave infrastructure, which today is an electronic infrastructure, the better off you're going to be. That doesn't mean lying down and becoming fooled, or letting foreign corporations run uncontrolled. But it does mean recognizing how important they can be in building the energy and telecom infrastructures needed to take full advantage of the Internet.
