【正确答案】 D

【答案解析】[解析] 5-7
The word“Sport”first meant something that people did in their free time. Later it often meant hunting wild animals and birds．About a hundred years ago the word was first used for organized games．This is the usual meaning of the word today． People spend a lot of their spare time playing football，basketball，tennis and many other sports．Some 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 sportsmen for only a few years， but during that time the best ones can earn a lot of money．
For example a professional football player in England earns more than 3000 pounds a year．The stars can earn a lot more．International golf and tennis champions can make more than $50000 in a year．Of course，only a few sportsmen can earn as mach money as that．Perhaps the most surprising thing about sportsmen and money is that the stars can earn more money from advertising than from sport．They allow the companies to use their names or a photograph of them and they are paid for this. Sport is no longer just something for people’s spare time．
