[精美语篇]

It is said that sports is an important form of life. Sports can help everyone keep healthy, enrich our life and maintain our psychological health, and help us relax after a period of exhausting work. A person who often takes exercise is always full of energy. Sports can also make people look younger than they really are. What's more, it produces chances to train our intelligence. Because we think actively when we do exercise.

My participation in sports tells me that sports can make us healthy both physically and psychologically. It is also a good way for people to know each other and can promote friendship between people. So long as we are careful enough, sports can do us nothing but good.

Personally, I love sports. I enjoy participating in sports. I feel that I not only gain a

well-balanced life through sports, but also get more chances to move closer to nature. Sports have really added happiness to my daily life.
