单选题Most people who develop Lyme disease, a tick-born infection that's endemic in parts of the Northeast and Midwest, are easily cured by taking an antibiotic like doxycycline for a couple of weeks. But for years a debate has raged over what to do about patients whose symptoms(fatigue, mental confusion, joint pain)never seem to clear up. One small but vocal group of doctors and patient advocates believes that Lyme's corkscrew-shaped spirochetes have tunneled deep into their victims' bodies and can be eradicated only with intensive antibiotic treatment over many months. Another group believes, just as adamantly, that the bacteria are long gone, making further treatment with powerful antibiotics— which can lead to potentially fatal infections or blood clots—positively dangerous. Now comes word of two studies in the New England Journal of Medicine that show that long-term antibiotic treatment is no better than a placebo for folks with chronic Lyme disease. Originally scheduled for publication in July, the research is part of a group of findings made public last week—just in time for the peak Lyme months of June and July. If confirmed by another major study that's looking at chronic Lyme and antibiotics from a slightly different perspective, the results would seem to settle the question once and for all. Researchers from Boston, New Haven, Conn., and Valhalla, N. Y., followed 129 patients who had previously been treated for well-documented cases of Lyme disease. Sixty-four were given antibiotics directly into their veins for a month, followed by two months of oral antibiotics. The others received dummy medications. A third of the chronic Lyme patients got better while taking the antibiotics. But so did a third of those on the placebo. Indeed, the results were so similar that a monitoring board decided to cut the trials short rather than add more subjects to the test groups. Unfortunately, the debate over chronic Lyme has become so heated that no one expects the controversy to go away. But both sides may take comfort in the other findings that were released by the New England Journal last week. After studying 482 subjects bitten by deer ticks in a part of New York with a lot of Lyme disease, researchers concluded that a singly 200-mg dose of doxycycline dramatically cut the risk of contracting the disease. That good news is tempered somewhat by the fact that 80% of patients who develop the infection don't remember ever being bitten by a tick.(The bugs inject an anesthetic into the skin to mask the pain and in their nymph stage are so small—about the size of a poppy seed—that they are easily overlooked.) There's still plenty you can do to protect yourself in a Lyme-infested neighborhood: tuck your pants in your socks, spray DEET on your clothing, check yourself and your kids for ticks. And if you develop a spreading red rash—particularly if it's accompanied by joint pain, chills or confusion—make sure you see a doctor right away. The trick, as always, is to be vigilant without overreacting.

单选题To understand how astrology works, we should first take a quick look at the sky. Although file stars are at enormous distances, they do indeed give the impression of being affixed to the inner surface of a great hollow sphere surrounding the earth. Ancient people, in fact, literally believed in the existence of such a celestial sphere. As the earth spins on its axis, the celestial sphere appears to turn about us each day, pivoting at points on a line with the earth's axis of rotation. This daily turning of the sphere carries the stars around the sky, causing most of them to rise and set, but they, and constellations they define, maintain fixed patterns on the sphere, just as the continent of Australia maintains its shape on a spinning globe of the earth. Thus the stars were called fixed stars. The motion of the sun along the ecliptic is, of course, merely a reflection of the revolution of the earth around the sun, but the ancients believed the earth was fixed and the sun had and independent motion of its own, eastward among the stars. The glare of sunlight hides the stars in daytime, but the ancients were aware that the stars were up there even at night, and the slow eastward motion of the sun around the sky, at the rate of about thirty degrees each month, caused different stars to be visible at night at different times of the year. The moon, revolving around the earth each month, also has an independent motion in the sky. The moon, however, changes it position relatively rapidly. Although it appears to rise and set each day, as does nearly everything else in the sky, we can see the moon changing position during as short an interval as an hour or so. The moon's path around the earth lies nearly in the same plane as the earth's path around the sun, so the moon is never seen very far from the ecliptic in the sky. There are five other objects visible to the naked eye that also appear to move in respect to the fixed background of stars on the celestial sphere. These are the planets Mercury, Venus, Mars, Jupiter, and Saturn. All of them revolve around the sun in nearly the same plane as the earth does, so they, like the moon, always appear near the ecliptic. Because we see the planets from the moving earth, however, they behave in a complicated way, with their apparent motions on the celestial sphere reflecting both their own independent motions around the sun and our motion as well.

Even small businesses that depend upon outside channels of retail distribution may have the final say in what prices they will charge, and great corporations can differentiate their goods in order to create demand of them. In this type of market, supply normally is very elastic--that is responsive to demand--in the short run. Stocks or inventories are held at some point in the chain of distribution; while stocks are running down or building up, there is time to change the level of production, and once a price has been set, it is rarely altered in response to moderate changes in demand. Even in a deep slump, defensive rings may be formed to prevent price cutting. In the long run, as well as in the short, supply is responsive to demand in the market for manufactures. It is easier to change the composition of a firm's output than it is to change the production of a mine or a plantation. And when changes in demand are not too rapid, gross profits from one plant can be siphoned off and invested in something quite different. When business is good, moreover, there is continual new investment so that productive capacity is adapted to meeting changing requirements. Workers themselves may not even be aware of changes in the final commodities to which their work contributes, and the level of wages for any grade of factory labour is very little affected by the fortunes of a particular market.

单选题A manufacturer of sports shoes starts selling consumer electronics. A soft drink lends its name to a range of urban clothing. What's going on? In simpler times, you knew where you were with brands. One brand name meant good-quality sports shoes, another a soft drink. No confusion. Today, however, big companies try to redefine brands as not so much a product, more a way of life, and stretch them into new areas. In the early years of the consumer society, a brand name on a box simply identified what was inside. People were looking for products that would improve their quality of life, and chose brands most likely to achieve that purpose. But as people in industrialized nations became more affluent and fulfilled their basic needs, brands acquired other attributes. The functionality of the product was still important, but people also started using brands to say something about themselves, for example, choosing a brand of cosmetics which would suggest that they were sophisticated jet-setters. Now, we have entered a third age of branding, in which so many companies are making roughly the same product at roughly the same price that functionality rarely succeeds as a point of differentiation. Instead, companies are trying to make their brands stand out by emphasizing their emotional aspects, hoping consumers will identify with the set of values the brand represents. One disadvantage of a product-based brand is that if the product goes out of fashion, the brand goes with it. This is a serious concern for manufacturers of breakfast cereals, who are struggling to counter weak demand for the products that bear their names. So far, their marketing efforts seem to be having little effect. The advantage of emotional brands is that companies can transfer their brand strength into other areas, increasing revenues and reducing their exposure to the lifespan of a single product. The elasticity of brands seems to be related to their position on a spectrum ranging from those rooted in solid, tangible assets to those with highly intangible, emotional qualities. At the one end, you have trained companies that tend to associate themselves with infrastructure and their ability to get you from A to B, and at the other end would be a leisure brand that positions itself on dreams and making people have fun. It is the latter which has the maximum potential for stretch. But even emotional brands have a limit to their elasticity. The merchandise has to be consistent with the brand promise. Just to sell merchandise with your logo on it is a short-term, mistaken idea. From this viewpoint, the decision to move from sports shoes into consumer electronics makes sense. Most items in the range, such as the two-way radio for hikers, are sports-focused, even though the products may be adopted as fashion accessories, and the sports shoe customers will probably snap them up. When the move was made from soft drinks into clothing, however, it left the branding consultants cold. It was a difficult mental leap into clothing from the drink so closely associated with that particular brand name. On the other hand, the emotional attributes that youngsters seem to find appealing in the drink, like its heritage and global appeal, are fashionable at the moment, and in fact response to the clothes with the same name has been overwhelming. Maybe this just shows that an inspired move—and by all accounts a snap decision—sometimes pays off against the odds, leaving the manufacturer laughing all the way to the bank.
