A man in a Paris hospital who needs blood, a woman in Mexico who was injured in an earthquake, and a family in India that lost their home in a storm may all be aided by the Red Cross. The Red Cross exists in almost every country around the globe. The world Red Cross organizations are sometimes called the Red Crescent, the Red Mogen Daid, the Sun, and the Red Lion.

In 1859, he observed how people were suffering on a battlefield in Italy. He wanted to help all the wounded people regardless of which side they were fighting for. The most important result of his work was an international treaty called the Geneva Convention(协定). It protects prisoners of war, the sick and wounded, and other citizens during a war. The American Red Cross was set up by Clara Barton in 1881. Today the Red Cross in the United States provides a number of services for the public, such as helping people in need, teaching first aid and providing blood. 56. A good title for this selection is .

It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat the right foods, get enough sleep and exercise regularly. Proper nutrition is important for good health. Your body cannot function well unless it receives the proper kind of “fuel”. Avoid foods with lots of sugar and fat. Eat plenty of foods high in protein, like lean meat, fish, beans and nuts. Vegetables and fruit are especially important because they provide necessary vitamins and minerals. However, dont overeat. It is not healthful to be overweight. Getting the proper amount of sleep is also important. If you dont get enough sleep, you feel tired and irritable(易怒的). You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality. Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp. Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your lifespan(寿命). Any kind of exercise is good. Most sports are excellent for keeping the body in good shape. Basketball, swimming, bicycling, gymnastics and running are all good examples. Sports are not only good for your body, but they are enjoyable and interesting, too. If everybody were to eat the right foods and get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser. 65.

Sleeping WellDWhat do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist may be able to put the tooth back in for you, but you have to get to the dentist first. In the meantime, you have to store the tooth so that it will stay healthy. The simplest thing to do is to put the tooth back into your mouth, or you could put it in milk. Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth. He tried putting teeth into milk, into water, and into cell-culture medium(细胞培养液). He also tried just drying the teeth in the open air. He used teeth that had to be removed from peoples mouths for various reasons. The teeth were put into one of the solutions(溶液) or stored in the air for one hour. Then cells from the root of the teeth were scraped off the teeth. Dr Courts and the others then studied how healthy these cells were. The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth. However, few people keep cell-culture medium handy at home or in school. The next best thing was milk. But Dr Courts said that the best thing of all was to wash the tooth and put it right back into its socket(牙槽) in the mouth. For some people, though, this is just too painful or upsetting.
