单选题High Rate of Stress among Doctors As the HIN1 swine flu virus spreads rapidly through the Northern Hemisphere, doctors and other health care professionals face a heavier - than - usual workload. Even without a flu pandemic, studies show, up to 60 percent of physicians in the United States suffer to some degree from" burnout" - physical and emotional exhaustion: The stress on doctors can cause medical mistakes even errors that could cost people their lives, so the universities that train America' s doctors are looking for ways to prevent burnout. At a hospital in Tennessee, Dr. William May tries to diagnose his patients as quickly as he can. "We don' t like to have to add that extra space. We' re just busy. Very, very busy, "he says. Even without a pandemic to add to the workload, doctors are busier than ever In Rochester, New York, primary -care physician Michael Schneider has seen the stress from his work increase steadily over the past 30 years. " It' s something lost when we have phones ringing, consultants calling, and computer screens flashing. "he says. Another study looks at how to help physicians cope with stress. Dr. Michael Krasner, leader of the study, saw a definite change in the doctors after a year of relaxation training. His theory is that physicians who have better communication skills, and who know how to relax when they can, can avoid symptoms of emotional exhaustion, such as a lack of a sense of accomplishment or difficulty empathizing with patients. Dr Schneider says the course helped him. "We are so removed from some of the skills we had all learned - or believed we had learned in medical school - about communication, that having an intensive course that really re-teaches and reinforces the skills that we had perhaps lost, is very valuable, "he says. This research highlights how important it is for doctors to address their own physical and mental well being, both for their own good and for that of their patients. The study appears in the journal of the American Medical Association.

单选题One Good Reason to Let Smallpox Live
It"s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?

单选题Not only is this a deadly way to practice medicine, but it's also a breathtakingly expensive one. In 2005 Americans paid out a record 16% of our gross domestic product for health care--a cool $ 2 trillion - making US the world's top spender on health care per capita. You might think we'd be getting some bang for those bucks, but our leading killer remains what it has been every year since 1900 (with the exception of 1918, when influenza claimed more lives ): heart disease, which kills nearly 650,000 of us each year. "The reason we rank so poorly is that we don't provide a basic - wellness infrastructure, "says Dr. Mehmet Oz, director of the cardiovascular institute at the Columbia University Medical Center and a host on the Discovery Health Channel. How much did the Americans pay for health care in 2005?A. 16% of their income.B. US $ 650,000C. US $ 2 i000,000,000,000D. US $1900 to US $1918 per person.

单选题The Greatest Show on Earth The Olympic Games are the greatest festival of sport in the world. Every four years, a hundred or more countries send their best sportsmen to compete for the highest honors in sport As many as 6,000 people take part in over 20 sports. For the winners, there are gold medals and glory. But there is honor, too, for all who compete, win or lose. That is the spirit of the Olympics-to take part is what matters. The Olympic Games always start in a bright color and action. The teams of all the nations parade in the opening ceremony and march round the track. The custom is for the Greek team to march in first. For it was in Greece that the Olympics began. The team of the country where the Games are being held-the host country-marches in last. The runner with the Olympic torch then enters the stadium and lights the flame. A sportsman from the host country takes the Olympic oath on behalf of all the competitors. The judges and officials also take an oath. Alter the sportsman march out of the stadium, the host country puts on a wonderful display. The competitions begin the next day. There are usually more than twenty sports in the Games. The rule is that there must be at least fifteen. The main events are in track and field, but it is a few days before these sports start. Each day the competitors take part in a different sport-riding, shooting, swimming, and cross-country running. Points are gained for each event. Medals are awarded for the individual winners and for national teams. More and more women are taking part in the games. They first competed in 1900, in tennis and golf, which are no longer held in the Olympics. Women's swimming events were introduced in 1912. But it was not until 1928 that there were any track and field events for women. Now, they compete in all but half a-dozen of the sports. In horse riding, shooting, anti boat racing, they may compete in the same events as the men.

单选题 Chewing Gum The practice of chewing, gum (口香糖) has been with us for more than a century. Millions of people all over the world chew billions of pieces of gum every year. Chewing gum became popular in the United States mainly because of the work of one man, William Wrigley, who for many years was head of the Wrigley Company. Earlier, Thomas Adams first began to experiment with chewing gum in about the year 1870. It was he who first made gum softer and pleasant to chew. But it was not until Wrigley entered the business in about 1890 that people everywhere began to learn about chewing gum and to use it widely. Wrigley liked to do things in a big way. In his first year, he borrowed money and spent more than a million dollars on advertising. For years, there was a large Wrigley's advertisement in every streetcar (有轨电车) in the United States. People complained that they could not go anywhere without seeing Wrigley's name. Wrigley even sent, free of charge, pieces of gum to every person in the telephone book of every city and town in the United States. Finally, he began to advertise that it was good for the health to chew gum and that it helped to keep the teeth clean. He used to send free gum to every child in the United States on his second birthday. He employed young women who, in beautiful dresses, would go from city to city in groups of four or five, stand on street corners, and give free chewing gum to every person who passed by. In this way, each woman gave away about five thousand pieces of Wrigley's gum every day. As a result of this continuous advertising, people in the United States naturally began to buy more and more chewing gum.
