December 1st was World AIDS Day. Our class organized the charity run to raise money for children suffered from the disease. It was the first time that we launched such an activity. We set about early in the morning from the school gate to the Center Square and their run lasted almost one hour .Because we had planned everything well, the journey was still a tough task. But instead of complaining about or giving up , all of us tried our best and managed to reach the finishing line. More important , with the supports of many people ,we finally raised over 10,000 yuan for the sick children. Exhausting as we were, we felt very happy to have such a meaningful experience.
