My favourite lesson is Physical Training. Usually we have our physical training lessons either in the gymnasium or on the sports ground. Our sports ground is situated behind the school. On the sports ground there are a football field, a volleyball ground and a basketball ground. Before the PT lessons we put on our sports uniform. After we have changed our clothes, we go to the gymnasium and line up. At the beginning of the lesson we usually do gymnastic exercises. Then we pull up, jump, climb the rope. On the sports ground we run. Sometimes we throw balls. We often play sports games at the PT lesson. All the boys in our form like to play football. But our girls prefer to play volleyball or basketball. In winter at the PT lessons we ski. We ski on the sports ground or in the park. Sometimes, if the weather is cold, we go to skate at the skating rink. The boys play hockey on the sports ground too. Many boys and girls of our form attend various sports sections. I also attend a sports section in swimming. Three times a week I go to the swimming-pool. Some of my friends go in for tennis, track-and-field athletics, boxing and other sports.
