My favorite sport-running, although I don't run as fast as Ruan and Huang, it is the best if I run hard and seriously.

At home, I run and walk with my mother every day. I can't talk when I run. I have to take a breath and blow two. I waved my arm and silently counted one, two and one. When my mother and I ran to catch my breath, I stopped for a walk, which helped me breathe fresh air. Sometimes I run fast and my legs are sore before I have a rest. At this time, you should pay attention to the running time, not too long, or you will be very tired.

There are more examples on campus than at home. After class, I will run and play games with my classmates in my spare time. There are not many opportunities for running. I remember one rainy day, when the rain stopped, several of our good friends felt cold and went to the playground for a race. At first, our feet were as cold as ice and could not move, but we persisted and won, and finally our feet became warm.

Another time, I left my exercise book at school. I used to take the underground passage from school and then go through the supermarket. It took me 30 minutes to get home. That time, I went back to school to get my exercise book, and then I went home. It took me 30 minutes, which was half as long as the usual time to go home from school.

I like running. I won't miss every opportunity.
