单选题What began with the invention of the telephone in 1876 has today become a global net of cables, satellites, transmitters, and receivers that enables half the population of the planet to exchange works, data, and images in seconds. It could take less than 25 years more to give the other half of the world's people this same power. The unified global telecommunications system, which is called "the Meganet", represents the greatest construction project ever undertaken. If present trends continue, by early in the 21st century the Meganet will link every computer terminal, fax machine, databank, and telephone instrument on earth. Unlike its anarchic (无政府主义的) cousin the Internet, which evolved from free interaction among interest groups of computer users. the Meganet of local telephone service, long-distance lines, communications satellites, and mobile relays has been planned, constructed, regulated and largely sponsored by governments and for-profit business interests. As new materials and technologies bring reliable voice and data links to formerly isolated or closed communities, political and economic power struggles grow. The Meganet breaks long-established patterns of social identity and responsibility. Where private individuals have uncensored access to global information sources, local standards of legality or decency become difficult even to set, let alone to enforce. Economic values may shift, too. Public utility companies have long supplied electric power over miles of high-tension lines, or pumped water through underground pipelines into thousands of homes. Now they are finding that their power-line rights-of-way and physical into-home connections let them compete with cable TV and phone companies to supply information services as well. Meganet impacts are often double-edged for finance and business, too. New York's Wall Street district lost 20% of its work force—some 100000 jobs—in less than a decade, as computers took over tasks once performed by clerks and banks did more of their business by phone transfers and automated teller machines.

单选题You've probably heard the reports that moderate drinking can actually be good for your heart. But before you stock up (囤积) on beer, wine, or liquor for "medicinal purposes", read the fine print. Guidelines published by the Department of Health and Human Services define moderate drinking as no more than a drink a day for most women and no more than two drinks a day for most men. But even moderate drinking may be ill-advised as you get older. Research shows that as you age, you absorb alcohol more readily and are more sensitive to its effects. So the number of drinks you could tolerate years ago may be too much for you now. Why? First, your body's ratio of water to fat falls as you age, so there's less water to dilute (稀释) the alcohol. Second, you have less blood flow to the liver and less efficient liver enzyme action, so your body doesn't metabolize (新陈代谢) alcohol as readily. Women need to be especially careful, since most can't tolerate as much alcohol as men can. One reason is that they are generally smaller, and smaller people have less blood volume, so a little alcohol goes a longer way. Women also produce less of the enzyme that breaks down alcohol in the stomach before it is absorbed into the bloodstream. And they have a higher proportion of body fat, which does not absorb alcohol. The result? Drink for drink, women have 750//00 more alcohol in their bloodstream than men do. Despite the caveats (警告, 告诫), there's no doubt that, for many people, limited amounts of alcohol can help you live longer and decrease your risk of heart disease. Those who may be at risk for heart disease or stroke and those who are diabetic appear to benefit most from moderate alcohol intake (one or two drinks per day) over the course of their lifetimes. For example, in a University of Wisconsin study of diabetic men and women with an average age of 69, the risk of death from coronary heart disease was significantly lower among moderate drinkers compared to abstainers (戒酒者). The death rate for those who had a drink a day was less than half of that for those who didn't drink at all.
