     Some people argue that the pressures on international sportsmen and sportswomen kill the spirit of

sport: the pursuit (追求) of personal excellence. Children kick a football around for fun. When they get

older and play for local school teams, they become competitive but they still enjoy playing. The sportsman representing his country cannot afford to think about enjoying himself, he has to think only about winning. He is responsible for an entire nation's hopes and dreams.

   A good example is the football World Cup. Football is the world's most important sport. It is even

more important now that the United States is seriously taking it up. Winning the World Cup is perhaps

eh greatest of international sporting success. Mention " Argentina " to someone and the chances are that

he'll think of football. In a sense, winning the World Cup " put Argentina on the map ".

     Sports fans and supporters get quite irrational about the World Cup. People in England felt that their

country was somehow important after they won the World Cup. Last year thousands of Scots sold their

cars, and even their houses, and spent all their money traveling to Argentina, where the finals were played.

     So am I arguing that international competitions kill the idea of sport? Certainly not! Do the

Argentineans really believe that because eleven of their men proved the most skillful at football, their

nation is better than all others? Not really. But it's nice to know that you won, and that in one way at least

your country is best.
