Hi, everyone! I am Li Ming, a middle school student. I am 14 years old and I am tall and strong. I'm also helpful. I'm always ready to help others.
My school life is very colourful. There are many kinds of activities in my school every afternoon. We can play basketball, football and other ball games on Mondays and Wednesdays. On Tuesdays, some students can go to watch English movies and some can listen to the broadcast programmes. On Thursdays, we also have interesting lessons. We have an art show on Fridays. And we are interested in all the activities. What pleasant weekdays we have! My school is really great. I really have a good time in my school.
