We didn't think we could win the dance competition, but we came in third overall. Please look at this table. It shows the scores of the top three dance teams. Igawa High School got the best score of the three teams for 5 dance technique, but they came in second overall. They danced very well, but they didn't smile enough. They needed more expression. In contrast, Heisei High School didn't get a high score for dance technique, but they got 86 points for dance expression. They were dancing with smiles. I enjoyed their dancing. To my surprise, we got better score than Heisei High School for dance expression. We started practicing for the dance competition two months ago. We practiced after school and on weekends to win the dance competition. We enjoyed dancing at first, but a month ago, we didn't enjoy it. When we were dancing, our English teacher, Mr. White, came to us and said, “Enjoy dancing! Relax more and dance with smiles. When ( ① ), the audience doesn't enjoy your 15 | dancing.' We found we didn't enjoy dancing. We practiced only to win the competition, and we forgot the most important thing.
