单选题The Internet can make the news more democratic, giving the public a chance to ask questions and seek out facts behind stories and candidates, according to the head of the largest U.S. online service. "But the greatest potential for public participation is still in the future," Steven Case, Chairman of America Online, told a recent meeting on Journalism and the Internet sponsored by the Freedom Forum(论坛). However, some other experts often say the new technology of computers is changing the face of journalism, giving reporters access to more information and their readers a chance to ask questions and turn to different sources. "You don't have to buy a newspaper and be confined to the four corners of that paper any more," Sam Meddis, online technology editor at USA Today, observed about the variety of information available to computer users. But the experts noted the easy access to the Internet also means anyone can post information for others to see. "Anyone can say anything they want, whether it's right or wrong," said Case. Readers have to determine for themselves who to trust. "In a world of almost infinite voices, respected journalists and respected brand names will probably become more important, not less," Case said. "The Internet today is about where radio was 80 years ago, or television 50 years ago or cable 25 years ago," he said. But it is growing rapidly because it provides people fast access to news and a chance to comment on it.

单选题Most scholars agree that Isaac Newton, while formulating the laws of force and gravity and inventing the calculus in the late 1600s, probably knew all the science there was to know at the time. In the ensuing 350 years an estimated 50 million research papers and innumerable books have been published in the natural sciences and mathematics. The modern high school student probably now possesses more scientific knowledge than Newton did, yet science to many people seems to be an impenetrable mountain of facts. One way scientists have tried to cope with this mountain is by becoming more and more specialized. Another strategy for coping with the mountain of information is to largely ignore it. That shouldn"t come as a surprise. Sure, you have to know a lot to be a scientist, but knowing a lot is not what makes a scientist. What makes a scientist is ignorance. This may sound ridiculous, but for scientists the facts are just a starting place. In science, every new discovery raises 10 new questions. By this calculus, ignorance will always grow faster than knowledge. Scientists and laypeople alike would agree that for all we have come to know, there is far more we don"t know. More important, every day there is far more we know we don"t know. One crucial outcome of scientific knowledge is to generate new and better ways of being ignorant: not the kind of ignorance that is associated with a lack of curiosity or education but rather a cultivated, high-quality ignorance. This gets to the essence of what scientists do: they make distinctions between qualities of ignorance. They do it in grant proposals and over beers at meetings. As James Clerk Maxwell, probably the greatest physicist between Newton and Einstein, said, "Thoroughly conscious ignorance... is a prelude to every real advance in knowledge." This perspective on science-that it is about the questions more than the answers-should come as something of a relief. It makes science less threatening and far more friendly and, in fact, fun. Science becomes a series of elegant puzzles and puzzles within puzzles—and who doesn"t like puzzles? Questions are also more accessible and often more interesting than answers; answers tend to be the end of the process, whereas questions have you in the thick of things. Lately this side of science has taken a backseat in the public mind to what I call the accumulation view of science—that it is a pile of facts way too big for us to ever hope to conquer. But if scientists would talk about the questions, and if the media reported not only on new discoveries but the questions they answered and the new puzzles they created, and if educators stopped trafficking in facts that are already available on Wikipedia-then we might find a public once again engaged in this great adventure that has been going on for the past 15 generations.

单选题 Whenever I hear a weather report declaring it's the hottest June l0 on record or whatever, I can't take it too seriously, because "ever" really means "as long as the records go back", which is only as far as the late 1800s. Scientists have other ways of measuring temperatures before that, though--not for individual dates, but they can ten the average temperature of a given year by such proxy measurements as growth marks in corals, deposits in ocean and lake sediments, and cores drilled into glacial ice. They can even use drawings of glaciers as there were hundreds of years ago compared with today. And in the most comprehensive compilation of such data to date, says a new report from the National Research Council, it looks pretty certain that the last few decades have been hotter than any comparable period in the last 400 years. That's a blow to those who claim the current warm spell is just part of the natural up and down of average temperatures--a frequent assertion of the global--warming-doubters crowd. The report was triggered by doubts about past-climate claims made last year by climatologist Michael Mann, of the University of Virginia (he's the creator of the "hockey stick" graph A1 Gore used in "An Inconvenient Truth" to dramatize the rise in carbon dioxide in recent years). Mann claimed that the recent warming was unprecedented in the past thousand years--that led Congress to order up an assessment by the prestigious Research Council. Their conclusion was that a thousand years was reasonable, but not overwhelmingly supported by the data. But the past 400 was--so resoundingly that it fully supports the claim that today's temperatures ale unnaturally warm, just as global warming theory has been predicting for a hundred years. And if there's any doubt about whether these proxy measurements are really legitimate, the NRC scientists compared them with actual temperature data from the most recent century, when real thermometers were in widespread use. The match was more or less right on. In the past nearly two decades since TIME first put global warming on the cover, then, the argument against it has gone from "it isn't happening" to "it's happening, but it's natural", to "it's mostly natural"--and now, it seems, that assertion too is going to have to drop away. Indeed. Rep. Sherwood Boehert, the New York Republican who chairs the House Science Committee and who asked for the report declared that it did nothing to support the notion of a controversy over global warming science--a controversy that opponents keep insisting is alive. Whether President Bush will finally take serious action to deal with the warming, however, is a much less settled question.

单选题Within hours of appearing on television to announce the end of conscription, President Jacques Chirac moved quickly to prevent any dissent from within the military establishment. Addressing more than 500 military staff officers at the military academy in Paris yesterday, Mr Chirac said clearly that he "expected" their loyalty in the work of rebuilding France's national defense. He understood their "legitimate concerns, questions and emotions" at the reforms, but added: "You must understand that there is not and never has been any rigid model for French defense. Military service has been compulsory for less than a century. Realism required that our armed forces should now be professional." The President's decision to abolish conscription over a period of six years removes a rite of passage for young Frenchmen that has existed since the Revolution, even though obligatory national service only became law in 1905. As recently as 1993, an opinion poll showed that more than 60% of French people said they feared the abolition of conscription could endanger national security. A poll conducted this month, however, showed that 70% of those asked favored ending of practice, and on the streets and in offices yesterday, the response to Mr. Chirac's announcement was generally positive. Among people who completed their 10-month period of national service in the last few years or were contemplating the prospect, there was almost universal approval, tempered by a sense that something hard to define—mixing with people from other backgrounds, a formative experience, a process that encouraged national or social cohesion—might be lost. Patrick, who spent his year in the French city of Valance assigning and collecting uniforms, and is now a computer manager, said he was in tears for his first week, and hated most of his time. He thought it was "useless" as a form of military training— "I only fired a rifle twice" —but, in retrospect, useful for learning how to get on with people and instilling patriotism. As many as 25% of those liable for military service in France somehow avoid it—the percentage is probably much greater in the more educated and higher social classes. According to Geoffroy, a 26-year-old reporter, who spent his time in the navy with the information office in central Paris, the injustice is a good reason for abolishing it. People with money or connections, he said, can get well-paid assignments abroad. "It's not fair: some do it, some don't." Several expressed support for the idea of a new socially-oriented voluntary service that would be open to both men and women. But the idea seemed less popular among women. At present, women have the option of voluntary military service and a small number choose to take it.
