As everyone knows that my classmates had some conflicts on the yesterday's Sports Day, and they had a fight. In fact, the objective of holding the Sports Day was to give a chance to everyone to show their ability in sports, learn to have team spirits and to build up our self confidence. However, the incidents happened yesterday had not met the school's goal. I am sorry that I had to cancel the Sports Day. Instead, we will hold a singing competition at school. The objectives of it will be similar to those for the Sports Day. We hope that everyone will learn from the competition. Furthermore, we will invite parents to be the judge so students as well as their parents can participate in this activity. I hope everyone will agree with my decision.
