When it was warm, our PE teacher took us to do outdoor sports. There were a football field together with a basketball court or running tracks, etc. in our school. I was good at running and loving to feel the air in my hair as I was approaching the finish line. It was also nice to have rest under the large trees and watch my classmate competing with each other. But not all memories of sports made me joyfully. One annoying memory was related to football. Once, someone hit the ball on his head heavily in a football game for two times. Besides, I had to sit on the bench for the rest of the game to stopping dizziness.
