A sports meeting was held in our school several days before. The last event was the 400-meter relay race, that had promised to be an exciting one. And so it was! Teams from every class joined in the race, but the winning team would be the champion of our school! So each player tries hard to win. The big crowd became quite silently and all of them had their eyes were focused as the team took their places. Heard the sound of the gun, the runners shot quickly and passed the relay sticks from one to another. Suddenly a runner from class 4 dropped his stick, but another runner picked them up and ran even faster. At the finishing lines, the runners from our class breasted the tape. Our class took a first place. Everyone cheered wildly and we felt extremely proud.
