    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 inShanghai,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.
