My favourite sport
My favourite sport is basketball, because basketball can make me strong and happy. It can also help me make more friends and learn teamwork.
I enjoy playing basketball with my friends. Kobe Bryant is my favorite player. I wish I can play basketball with Kobe Bryant one day.
Fishing is my favourite sport. I like fishing but I hardly get any fish. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all. Anyway I think fishing can make me feel very relaxed and comfortable.
I like swimming because I think it's a funny and easy sport. And swimming is more popular than running. Swimming is good for my health. It can help me keep fit. I joined the swimming club last term. I hope to swim very fast and beautifully. I want to keep my body in a good shape.
I enjoy jogging with my friends Tommy and Betty. In the early mornings, we often go jogging in the park. Then we are ready for school. At weekends, we sometimes go jogging in the countryside. The more I go jogging, the healthier I will feel.
