Being a volunteer can bring much benefits to us. We can learn new skills, gain valuable experiences, meet new people and so on. In the late August last year, I took part the voluntary work for a international sports meeting. Every day I worked in the supply office in the Athlete Villages for about seven hours. My job is to deliver daily supplies to the officials and athletes. When the sports meeting closed, I finished my job successful. Though the job was hard, but it was very meaningful. I made some friends with the people live there and some athletes from all around the world. This voluntary work also enriched your working experience, from that I learned some skills as well.
