It is well-known that sports is one of the life value. With the increasing competitive society developing, a number of parents more care about their children physcial fitness and want to their children  attend competitions instead of  just for fun. I believe that we should support this opinion. Because competitive sports could help children adapt the step of society, arousing enthusiasm of sports and train their teamwork ability.We all know that this world is a competitive where we live, people need attend competitions from born to tomb, if not, the result is be excluded from modern society. The children who take part in competitive sports will know how to catch the step of society. Woshibiande, a successful enterpriser of China, said that one of  factors about his achievement is attending sport competition when he was a child. From these, he could study how to adjust his mentality about win or lost so that he will make himself optimistically. He always say," I have and will meet a lot of hinders and difficults, however, thanks to my mother, she encourage me to attend some competitive sports, such as 100-metre race, basketball and swimming, which let me keep a strong mind to face them and never give up." No doubt that taking competitive sports will help children for fit now fierce competition.Moreover, arousing enthusiasm of sports also a reason why encourage children take part in competitive sports. The scientific research from China Development Association shows that the children who attend competitive sports keep five or more hours sport time a week, however,  the children who attend sports just for fun are only two or three hours sport time a week. Some children think that it give them a honor to take competitions when they win the sport game and make them confidently. On a related note, some children are overweight and not much enthusiasm because the items can not cause their passion.Last but not the least, some competitions will bring teamwork ability. In the increasing economic world, most employers have tendency to employees who have teamwork ability. Some parents think that some sports will develop their children's skills of talk with strangers and children also can make friends during the matches. Basketball, baseball, football etc. maybe good choices. We know that not basketball, not Mingyao and his partners, of course not business empire today. Competitive sports not only give people healthy body but also equip them sociability which helps them access to the success.Some parents worried about that competitions may hurt children. There are many examples about sports injury. So children attend sports only for fun is better. But no one can promise there are nothing if children play sports just for fun and could  avoid injury. I support that children should play competitive sports but in morderation.
