Not long age, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night? Tests with artificial stars have proved that certain night - flying birds are able to follow the stars in their long - distance flights.
A dove (鸽子) had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star - filled sky. (76) The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.
(77) But the stars are apparently their principal means of navigation (航行) only. When the stars are hidden by clouds, they seemingly find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.

Soon, a golden-haired boy appeared. "Do you have a job for me?" he asked. I told him about a system for sorting books. He picked up the idea immediately. Then I showed him some cards for some unreturned books that I thought had been returned but not recorded. Maybe some books were put on wrong places. He said, "Is it a kind of a detective(侦探) job?" I answered yes, and then began his work.
He had found three books with wrong cards by the time his teacher opened the door and said, "Time for rest!" he argued for finishing the finding job, but the teacher won.
The next morning, he arrived early, "I want to finish these books," he said. At the end of the day, when he asked to work with me more often, it was easy for me to say yes.
After a few weeks I found a note on my desk, inviting me to dinner at the boy's home. At the end of a pleasant evening, his mother declared that the family would be moving to another school. Her son's first concern, she said,was leaving the library. "Who will find the lost books?" he asked.

One country received its second-place medals with visible indignation after the hockey final. There had been noisy scenes at the end of the hockey match, the losers objecting to the final decisions. They were convinced that one of their goals should not have been disallowed and that their opponents' victory was unfair. Their manager was in a rage when he said: "This wasn't hockey. Hockey and the International Hockey Federation are finished." The president of the Federation said later that such behavior. could result in the suspension of the team for at least three years.
The American basketball team announced that they would not yield first place to Russia, after a disputable end to their contest. The game had ended in disturbance. It was thought at first that the United States had won, by a single point, but it was announced that there were three seconds still to play. A Russian player then threw the ball from one end of the court to the other, and another player popped it into the basket. It was the first time the USA had ever lost an Olympic basketball match. An appeal jury debated the matter for four and a half hours before announcing that the result would stand. The American players then voted not to receive the silver medals.
Incidents of this kind will continue as long as sport is played competitively rather than for the love of the game. The suggestion that athletes should compete as individuals, or in non-national teams, might be too much to hope for. But in the present organization of the Olympics there is far too much that encourages aggressive patriotism.

A.mated goodwill between the nations
B.bred only false national pride
C.barely showed any international friendship
D.led to more and more misunderstanding and hatred
