làm hộ mik nhoa~ Exercise 1: Read and answer the questions. My last Sports Day occurred on the 8th of September in 2016. On that day, the school was beautifully decorated with colorful flags. Parents were invited to watch their children participate in many events. In the morning, our class was divided into four groups and they competed against one another. The children used balls, hoops, skipping-ropes and bags in the competition. The parents cheered them very much. In the afternoon, we had more interesting events. The Upper Primary students competed in many sports such as hurdles, relay races, short distance races, high jump and long jump. Every participant tried their best to win as many trophies as possible for their team. The prize-giving ceremony marked the end of the exciting day. The winners were cheered and carried on their classmates’ shoulders. Though we were very tired, we had enjoyed ourselves very much. 1.
