　　Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's 11 one of the scientists wrote in his book, "Look here for 12 metal. " Scientists in another airplane, flying over a mountain region, sent a 13 to other scientists on the ground, "Gold possible. " Walking across hilly ground, four scientists reported, "This ground should be searched for metals. " From an airplane over a hilly wasteland a scientist sent back by radio one word, "Uranium. "
　　None of the scientists had X-ray eyes: they had no 14 powers for looking down below the earth's surface. They were 15 putting to use one of the newest methods of      16      minerals in the ground—using trees and plants as 17 that certain minerals may lie beneath the ground on which the trees and
plants are growing.
　　This newest method of searching for minerals is      18      on the fact that minerals deep in the earth may      19      the kind of bushes and trees that grow on the surface.
At Watson Bar Creek, a brook six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was 20    marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it.

　　Sport is one of the world’s largest industries, and most athletes are professionals who are paid for their efforts. Because an athlete succeeds by achievement only—not by economic ground or family connections—sports can be a fast route to wealth, and many athletes play only for money than for love.
　　This has not always been true. In the ancient Olympics the winner got only a wreath of olive leaves （橄榄叶花环）. Even though the winners became national heroes, the games remained amateur for centuries. Athletes won fame, but no money. As time passed, however, the contests became increasingly less amateur and cities began to hire athletes to represent them. By the fourth century A.D., the Olympics were ruined, and they were soon ended.
　　In 1896, the Olympic games were revived （使再度兴起） with the same goal of pure amateur competition. The rules bar athletes who have ever received a $50 prize or an athletic scholars or who have spent four weeks in a training camp. At least one competitor in the 1896 games met these qualifications. He was Spiridon Loues, a water carrier who won the marathon race, after race, a rich Athenian offered him anything he wanted. A true amateur, Loues accepted only a cart and a horse. Then he gave up running forever. But Loues was an exception and now, as the Chairman of the German Olympic Committee said, “Nobody pays any attention to these rules.” Many countries pay their athletes to train year-round, and Olympic athletes are eager to sell their names to companies that make everything from ski equipment to fast food.
　　Even the games themselves have become a huge business. Countries fight to hold the Olympics not only for honor, but for money. The 1972 games in Munich cost the Germans 545 million dollars, but by selling medal symbols, TV rights, food, drink, hotel rooms, and souvenirs （纪念品）, they managed to make a profit. Appropriately, the symbol of victory in the Olympic games is no longer a simple olive wreath—it is a gold medal.
