Last year, my school organized table tennis competition for all fourth-year students. I had never played on a proper table tennis court ago, or against such good players. In the first match I was against Wang Peng, who uses a special bat to hit the balls really hard. It came over the net so fast that he hardly saw it. I never stopped running and jumping, and soon I was out of my breath and had very little energy leaving. 1 was sure if Wang Peng would easily beat me, but then, sudden, he stopped. He received an injury to his right ankle, but he needed treatment from the school nurse. I won!
