I am a healthy girl ,because i like exercising,it’s good for our body.And my favorite exercise is swimming.It’s really interesting .every summer ,i always swim in the sea ,it makes me feel comfortable ,and i can swim very well ,my friend said that i like a fish in the sea.but some people may say it is easy to hurt while swimming.Yes,that’s right.But let’s face it,the advantages of sports far outweigh any risk of doing sports.Sports measure up to the expectations of people.Most of us love sports.We should follow the lead of sports athletes,as sports play an essential role in our life.Plenty of physical exercise will help you keep in shape.
