This summer holiday,I learnt to ride a bike. Because when I am going to the middle school, I must go to school by bike. My father bought a new bike for me. In the weekends, he taught me how to ride it. At first, I was nervous. I always felt that I would fall down from my bike. My father encouraged me to be brave. And he would help me and protect me. Then I was not so worried. I could ride it slowly. After two weekends, I learnt it. I could ride it by myself. I was so excited. My father was proud of me, too.
