If you want to keep fit, you should go in for sport. Sport is an important part of my daily life. Every morning I do morning exercise. In summer I go swimming or rowing. I usually spend my winter holidays in the country where I ski, skate or toboggan.

Different sports and games are popular with my classmates. All my friends go in for different kinds of sport such as gymnastics, wrestling, boxing, football, basketball, volleyball etc. We have teams at our school and different kinds of competitions take place there. The boys of my school are crazy about football and the girls are football fans. They never miss a match played by school teams.

In winter our PE lessons are held outdoors. We go skiing or skating. When it’s cold outside we have PE lessons in the gym. We play basketball or volleyball. In autumn and spring when the weather is warm we have lessons at our stadium. I love sport very much.
