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.

单选题Walking Barefoot Can Help Prevent Some Injuries Walking barefoot helps to improve balance, posture and prevent common foot injuries, according to an American researcher. Patrick McKeon, a professor at Ithaca College"s School of Health Sciences in New York, says the more people go barefoot at home, in the office or outside, the healthier their feet will be. He believes the small, often overlooked muscles in the foot play a vital but underestimated role in movement and stability, similar to the core muscles in the abdomen. The researcher explained their importance by describing the cycle of feedback between the large "extrinsic" (外在的) muscles in the legs and feet, the smaller "intrinsic" (内部的) muscles in the feet, and the neural connections that send information from them to the brain. When this cycle is broken, it can lead to overuse injuries that most athletes are familiar with. Shoes can also have a negative effect on this cycle, McKeon explained. "When you put a big sole underneath, you put a big dampening effect (阻尼效应) on that information. There"s a missing link that connects the body with its environment." Without the information provided by the small muscles in the foot, the larger muscles over-compensate and over-exert beyond the point of their natural ability to maintain and repair themselves. And when these muscles are no longer able to absorb the forces of activity, the forces are transferred to the tendons (肌腱), bones and ligaments (韧带), resulting in an increased risk of injury. McKeon says the only way of reintroducing this link and reactivating the cycle is to take off our shoes and strengthen the muscles in our feet by walking barefoot.
