Discuss these opposing views and give your own opinion. Much thought is being given to sport these days. The debate about sport tends to divide people into two camps. Some people think that sport is important for children, while others believe that it should be purely optional. On the plus side, people believe that sport is the cornerstone of a happy and healthy life. By exercising, children can recharge their batteries and have more energy to do their schoolwork. Besides, some chronic illnesses have grown into public-health crisis, such as diabetes and cervical spondylosis. Exercising can help contain these illnesses. On the minus side, people feel exercising should be purely optional. Some children may not like sport, and they might want to read books rather than exercise in their spare time. Moreover, some sports are not safe so that children may have a chance to get injured. Based on the above discussion, I think we should give a priority to sport for it can help us become healthier. In my opinion, reasons for exercise abound, but three reasons stand out. The most important is that we are living in an environment where there is much pollution, such as air pollution and water pollution. If ever there is a method that helps us improve our immune function, exercise is the one. A second reason is that exercise makes people happy for it stimulates the brain to generate dopamine, an organic chemical that plays several important roles in the brain and body. Lastly, some sports need teamwork, which helps children have a better understanding of cooperation and competition. All things considered, sport brings many benefits to children, so it is of great importance to make sport an essential part of school life. If children develop a habit of exercising at school, it will have a good impact on them during their lifetime.
