Zinc (锌) is one of about 20 elements necessary for good health. It is present in the body in a very small amount, but it makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work.

Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys, formerly with the United States Air Force, noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate (硫酸盐) recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate.

The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein foods, such as meat milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these foods. Food markets should add these elements so that more people could get needed amount of these necessary matters.

1. Which of the following statements is true?

A. Scientists found how zinc works a long time ago.

B. People need a large amount of zinc to be healthy.

C. Zinc allows important chemical actions to take place in cells.

D. Zinc must be used in the course of medical operation.

2. One of the results from the study of zinc is that _________.

A. there's only a little zinc in the human body

B. food rich in protein contains more zinc

C. some physical problems are caused by lack of zinc

D. any patient who receives zinc sulphate gets well immediately

3. The best title for the passage may be ________.

A. A New Discovery               B. Zinc and Health

C. How Zinc Works              D. Add Zinc to Your Food

Sports can help you keep fit and get in touch with nature.However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

Some sports are resource-hungry.Golf, as you may know, eats up not only large areas of countryside, but also tons of water.Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition.This causes major environmental effects.For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

There are many environment-friendly sports.Power walking is one of them that you could take up today.You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse.Simple and free, power walking can also keep you fit.If you walk regularly, it will be good for your heart and bones.Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials.But the final goal should be “green gyms”.They are better replacements for traditional health clubs and modern sports centers.Members of green gyms play sports outdoors, in the countryside or other open spaces.There is no special requirement for you to start your membership.And best of all, it’s free.

      A.it improves our health   B.it uses fewer resources

      C.it is an outdoor sport      D.it is recommended by experts
