Zinc(鋅) is one of about 20 elements necessary for good health. It is present in the body in a very small amount but 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(硫酸鹽) 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(蛋白質(zhì)) foods such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these food. 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

     James Cleveland Owens was the son of a farmer and the grandson of black slaves. His family moved to Cleveland when he was 9. There, a school teacher asked the youth his name.

    “J. C.，" he replied.

     She thought he had said “Jesse", and he had a new name.

    Owens ran his first race at age 13. After high school, he went to Ohio State University. He had to work part time so as to pay for his education. As a second?year student, in the Big Ten games in 1935, he set even more records than he would in the Olympic Games a year later.

     A week before the Big Ten meet, Owens accidentally fell down a flight of stairs.His back hurt so much that he could not exercise all week, and he had to be helped in and out of the car that drove him to the meet. He refused to listen to the suggestions that he give up and said he would try, event by event. He did try, and the results are in the record book.

     The stage was set for Owens' victory at the Olympic Games in Berlin the next year, and his success would come to be regarded as not only athletic(體育的) but also political. Hitler did not congratulate any of the African?American winners.

     “It was all right with me," he said years later. “I didn't go to Berlin to shake hands with him, anyway."

     Having returned from Berlin, he received no telephone calls from the president of his own country, either. In fact, he was not honored by the United States until 1976, four years before his death.

     Owens' Olympic victories made little difference to him. He earned his living by looking after a school playground, and accepted money to race against cars,  trucks, motorcycles, and dogs.

     “Sure, it bothered(煩擾) me," he said later. “But at least it was an honest living. I had to eat."

     In time, however, his gold medals(獎(jiǎng)牌) changed his life. “They have kept me alive over the years," he once said. “Time has stood still for me. That golden moment dies hard."

The science of physics today is as current as the morning newspaper. Indeed,as

a result of new advances in physics and their rapid application to inventions designed to satisfy man's wants, the world ?itself? has been changing rapidly. Space technology, industrial technology, and the technology of the home, the farm, the office, the bank, and the department store have all been revolutionized.

Clearly, every grown?up today would understand the world he lives in much better if he knew something about physics. Whether it be Congress(美國國會(huì)) voting huge sums of money for new ?warships,? space exploration, or atomic energy；the office staff learning to use a new computer；son Bobby wanting to know about going to the moon；or the housewife learning to operate a new electric stove physics seems to be everywhere.
