Talk about the things you like doing in your free time

There are three activities I like to do in my free time. The first is cartoon. I like watch cartoons very much. I love “Total Spies” most because it is very exciting and funny. I often watch it with my friends to relax. Second, I also play football with my brother and my friends when I have free time. I often play it in our school yard. I think playing football is sport which helps us have good health and study better. Final, I like reading books best. Since reading books are good, you can learn about another culture and again your knowledge. Moreover, it is a form of entertainment, which is useful to our life. All in all, I find that if I haven’t anything to do in my free time, I will be boring. Therefore, you should also choose some activities for yourself to do, which helps you have healthy way of life.
