　　I had much unforgettable experiences in the three years in high school. One of them were that our class prepared for a group singing competition. In order to win a competition, we went all out for them. During the week before the competition, we practiced sing in our free time. Although it was a hard job, but every participant took it serious and did their best. Thanks to our efforts, we won the first prize. Hearing the excited news, we were all wild with joy. The moment we got the prize, an old saying occurred me - "no pains, no gains". Besides, during the course of preparation, we develop friendship, confidence as well as understanding.

　　Last Sunday, our volunteer group took part in a voluntary activity at the bus station.

　　On arriving there, we were given a warm welcome. Some students helped clean the waiting room; some students offered the information that passengers needed; some students helped passengers carry their luggage. We all did what we could to help those in need of help. Although we were tired, we felt happy and proud when we saw the smiles on passengers' faces.

　　This experience made us become aware of the importance of helping others. In future, we'll try our best to do more voluntary work.
