What is the purpose of world sporting events,such as The Oly

As we all know,The Olympic Games or the World Cup are very famous.That's why the businessmen want to take part in those big events.They want to share whatever are from these games,profits,reputation,and so on.However,what we didn't see is that they also bring a country culture to another country,even to a whole continent!This is a big outcome of that.How impressive!Didn't we know Pepsi brand of USA from the World Cup?Didn't we know much better about China because of the Olympic Gamse?We are not supposed to ignore all the impact that these games have brought us because they did seriously influence our lives.
So in all,I think these sporst events are quite necessery to hold,especially for young people.In our society now,young peole gradually lost their confidence to take a chance for themselves.These are what they need for their future!Encouraging,exciting,these are more important than just an ordinary life.Do you think so?
都是自己想的啊,我的观点也许跟别人不同,仅供参考.

This is the symbol of the country strong

世界的目标是什么运动,如奥运会或世界杯吗?他们变得非常昂贵而且太专注于广告呢?
