    My future
    In twenty years, I think I will be a police officer. I will be a tall and strong man with short hair. I will live in Shanghai, because I think it is a beautiful city and I like it very much. I will live in a big apartment with my family. I will have two children, and I will play with them on the weekends. I will go swimming and play basketball every day because I think doing sports is good for our health.
