But after a lap (圈), I fell behind him and had great 5 in breathing. After two laps, my foot began to hurt, 6 I had to slow down and began to run at my usual speed. This time I could breathe again and the pain in my foot went away. In a very short time, I was far behind him. He was too fast for me to 7 .
