单选题To understand how astrology works, we should first take a quick look at the sky. Although the 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, maintains fixed patterns on the sphere, just as the continent of Australian 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 an 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 the 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.

单选题 About 50 years ago the idea of disabled people doing sports was never heard of. But when the annual games for the disabled were started at Stroke Mandeville, England in 1948 by Sir Ludwig Guttmann, the situation began to change. Sir Ludwig Guttmann, who had been driven to England in 1939 from Nazi Germany, had been asked by the British government to set up an injuries centre at Stroke Mandeville Hospital near London. His ideas about treating injuries included sports for the disabled. In the first games just two teams of injured soldiers took part. The next year, 1949, five teams took part. From those beginnings things developed fast. Teams now come from abroad to Stroke Mandeville every year. In 1960 the first Olympics for the Disabled were held in Rome. Now, every four years the Olympic Games for the Disabled are held, if possible, in the same place as the normal Olympic Games, although they are organized separately. In other years Games for the Disabled are still held at Stroke Mandeville. In the 1984 wheelchair Olympic Games, 1, 604 wheelchair athletes from about 40 countries took part. Unfortunately, they were held at Stroke Mandeville and not in Los Angeles, along with the other Olympics. The Games have been a great success in promoting international friendship and understanding, and in proving that being disabled does not mean you can't enjoy sports. One small source of disappointment for those who organize and take part in the games, however, has been the unwillingness of the International Olympic Committee to include the disabled events at the Olympic Games for the able bodies. Perhaps a few more years are still needed to convince those fortunate enough not to be disabled that their disabled fellow athletes should not be excluded.

单选题Sleep plays a major role in preparing the body for an alert and productive tomorrow. But sleep is not a period of inactivity. The sleeping brain is highly active at various times during the night, performing numerous "house keeping tasks". These keep us alive and aid our ability to think and remember. Sleep also energizes the body and brain. Most people spend one-third of their lives sleeping and this will affect the other two-thirds in terms of alertness, energy, moods, body weight, perception, memory, thinking, reaction time, productivity and performance. To limit sleep means our health and daytime potential are significantly reduced. So, good sleep strategies are essential in order to feel energized day after day. There is no strategy which works for everyone, so each person needs to experiment. One important thing is that you shouldn"t worry too much if you go a few nights without a lot of sleep. It won"t ruin your life. On any given night, one in four people can"t sleep properly and everyone suffers from a lack of sleep at some time. How does one minimize this problem? It is really quite simple. The first thing you must do is to reduce stress as much as possible. Stress is part of everyday life and, while we can never be entirely without stress, it can be managed. This means taking control of your life and focusing on what is important. One sleeping strategy is to sit in a comfortable position, close your eyes and relax all your muscles, breathing easily through your nose. Continue this for ten to twenty minutes. This should help you reduce stress and sleep better. Or, you can try getting plenty of exercise, because a tired body is likely to sleep better.

单选题Queuse are long. Life is short. So why waste time waiting when you can pay someone to do it for you? In Washington D. C.—a city that struggles with more than its share of bureaucratic practices—a small industry is emerging that will queue for you to get everything from a driver"s license to a seat in a congressional hearing. Michael Dorsey, one of the pioneering "service expediters", began going to traffic courts for other people back in 1988. Today his fees start at $ 20 and can go into the thousands to plead individual cases at the Bureau of Traffic Adjudication (his former employer). Mr. Dorsey knows what a properly written parking ticket looks like, and often gets fines invalidated on its failures in formality. His clients include congressmen and diplomats, as well as firms for which tickets are an occupational hazard, such as taxi operators and television broadcasters. Service expediters are not universally loved. Non-tax income, like fines and fees, makes up about 7% of local-government revenue in Washington. Mr. Dorsey alone relieves that fund of $150,000 a year. Meanwhile, citizen advocacy groups keep complaining about expediters such as the Congressional Services Company and CVK Group that specialise in saving places for congressional hearings. Committees hearing hot topics such as energy regulation often do not have enough seats. Why should a well-heeled lobbyist who has paid $ 30 an hour to a professional place-holder grab the place? Critics say this perpetuates a two-layered system: the rich get good government service, but the poor still have to wait. This seems a little harsh. Service expeditors can hardly be blamed for creating the unfair system they profit from. Anyway, it"s not only rich corporate types who benefit from their services. Poor foreigners with little English hire expediters to navigate the ticket-fighting process; so do elderly and disabled people who want to save time on errands that require long hours standing in line. And, who knows, the service expediters might even shame the bureaucrats into pulling their socks up. Back in 1999, Washington"s mayor, Tony Williams, promised to liberate citizens from the tyranny of the government queue. Things have gotten a bit better, but the 20-minute task of renewing a driver"s license can still take days. Hiring an expert to confront the bureaucratic beast on your behalf takes care of that.
