My track and field coach, Mr Jones, had decided to get the team to take part in the 4x100m race. It would be the first time that we were running in such a race. We needed to work as a team to improve on our speed. The most critical moment was the passing of the baton (接力棒) at the right time to the next runner.

Mr Jones had chosen me to start the race. The next runner would be Susan. In the beginning, whenever we practised passing the baton, something would go terribly wrong. I would either be going too slowly or she would be taking off too late. We needed to perfect it. At the same time, I had to make sure that I would not go beyond the yellow line.

Finally it was the day of the race. We were confident that the gold medal would be ours. Each of us had improved in our running speed. Our passing of the baton had been perfected during the practices.

My reactions were exact and accurate as I started running. Everything felt the way it should as I sprinted towards Susan. I held the baton in my sweaty palms, promising myself not to let go. My long legs moved me as fast as I could go round the comer. As I came closer to my final steps, my heart was beating faster than usual. The cheering by the spectators (观众) got into me and I became nervous. “What if we lose?” I thought to myself. It was then that I saw Susan in the far distance.

I held out the baton and continued running quickly towards Susan. Susan yelled “Slow down, slow down!” However, it was too late. The official held up the red flag. It was then that I realized that I had gone beyond the yellow line.
