Everywhere you look, you see kids bouncing a basketball or waving a tennis racquet (网球拍） And these kids are getting younger and younger. In some countries, children can compete on basketball, baseball, and volleyball teams starting at age nine.（1）And swimming and gymnastics classes begin at age four, to prepare children for competition. 
It's true that a few of these kids will develop into highly skilled athletes and may even become members of the national Olympic teams.（2）This emphasis on competition in sports is having serious negative effects. 
Children who get involved in competitive sports at a young age often grow tired of their sport. Many parents pressure their kids to choose one sport and devote all their time to it.（3）But 66 percent of the young athletes wanted to play more than one sport--for fun. 
Another problem is the pressure imposed by over-competitive parents and coaches. Children are not naturally competitive. In fact, a recent study by Paulo David found that most children don't even understand the idea of competition until they are seven years old.（4） 
The third, and biggest, problem for young athletes is the lack of time to do their homework have fun, be with friends--in short, time to be kids. When they are forced to spend every afternoon at sports practice, they often start to hate their chosen sport. A searchers found that 70 percent of kids who take part in competitive sports before the age of twelve quit before they turn eighteen.（5）Excessive competitive away all the enjoyment. 
Need to remember the purpose of youth sports--to give kids a chance to have developing strong, healthy bodies.
