8、Questions {TSE}are based on the following passage.

Some people, believe that international sport creates goodwill between the nations and that if countries play games together they will learn to live together. Others say that the opposite is true : that international contests encourage false national pride and lead to misunderstanding and hatred. There is probably some truth in both arguments, but in recent years the Olympic Games have done little to support the view that sport encourages international brotherhood: Not only was there the tragic incident involving the murder of athletes, but the Games were also ruined by lesser incidents caused principally by minor national contests.

One country received its second medals with visible indignation(愤怒) after the hockey(曲棍球) 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 opponent's 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 (暂令停止参加) 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, disorder. 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.
