题目：
The word "sport" first meant something that people did in their spare time. Later in often meant hunting wild animals and birds. About a hundred years ago the word was used for organized games. This is the usual meaning of the word today. People spent a lot of their spare time playing football, basketball, tennis and many other sports. Such people play because they want to. A few people are paid for the sport they play. These people are called professional sportsmen. They may be such sportsmen for only a few years, but during that time the best ones can make a lot of money.
For example, a football player in England earns more than 50,000 pounds in a year. Of course, only a few sportsmen can earn as much money as that.
It is possible for middle class people to engage in sports like golf, tennis and motor-racing. Perhaps the most surprising thing about sportsmen and money is this: the stars can earn more money from advertising than from sport.
An advertisement for sports equipment does not simply say "Buy our things." It says, "Buy the same shirt and shoes as...". Famous sportsmen can even advertise things like watches and food. They allow the companies to use their names or a photo of them and they are paid for this. Sport is no longer just something for people’s spare time.
