B
Jack’s mother bought him a new bike two months ago. She hoped it could help Jack go to school faster and have fun at weekends. Before Jack got the bike, he often played basketball on the school playground after school.
But things were different after he got it. As soon as school ended, he rode the bike home quickly and spent lots of time on it. At first, he just rode around the neighbourhood (社区). He was excited to enjoy the wind. Later, he liked to show off his riding skills to his friends. His mother was worried about his safety and studies. She always told him not to ride too much and not to forget his homework. Jack knew his mother was right, but he couldn’t stop himself.
Last week, Jack did badly in his Chinese test. His mother was really angry and said he could only ride the bike for an hour at weekends. She also told him to listen carefully in class and do his homework on time.
Jack thought it was time to change and study hard at school.
