Trainers and parents saw children play sports at a young age and then saw them become experts．Many think the training is helpful to success．Competitive sports are good for young children because they teach children life skills，provide health benefits，and offer special chances．
To begin with，sports teach children life skills．Once a formal athlete stated，“I played soccer in high school and college and found team sports weren't just about winning，but also about developing a solid ethic (行为准则)．” In short，playing highly competitive sports teaches kids many life skills like teamwork．People will have to use teamwork for the rest of their lives，and sports can help them improve that skill．Taking part in sports can help people behave actively in life in the long run．
Sports are also good for kids because they provide health benefits．It is healthier for a kid to play a sport competitively than to waste time playing video games all day．What's more，a research group of the University of California said，“96 percent of the participants said they enjoy their sports．They're all loving life．” That is to say，playing highly competitive sports are more possible to enjoy life instead of doing something else like watching TV．
On the other hand，some people might argue that competitive sports are bad for young children because they are so time consuming．However，the time spent does not rob(掠夺) kids of their childhood，but offers special chances．Athletes can get success to live their dream lives by playing sports．
In a word，competitive sports are good for children because they can provide wholesome (有益身心的) benefits，create new experiences，and build skills that will last a lifetime．

If you do not know how to swim，adult lessons are often available at gyms． 2 You can learn how to more effectively work out in the pool with just a few lessons．Swimming styles include freestyle，backstroke，breaststroke and butterfly．
3 It is important that you stick to the posted guidelines，which are meant to keep the swimming pools running properly．There are different rules for different pools．But the majority request that you shower before you enter the pool． 4
You will find that there are also posted rules about using the lanes (泳道) of the pool．This simply means that the pool is divided up so multiple people can use it at the same time．At times，you may share a lane with one or more other swimmers． 5 You need to stay in the appropriate lane．Find a lane in the pool where the other swimmers are similar to you．When several swimmers are using the same lane，all swimmers swim in a counterclockwise (逆时针方向的) direction．
