英语作文：作为志愿者参加残奥会你作为志愿者参加了残奥会，根据以下信息，叙述这次活动的过程及感受 7:20鸟巢体育场集合

My classmates and I worked as volunteers in Beijing Paralympics. Early in the morning at 7:20, we gathered at the National Stadium, the Bird Nest. As soon as we got into it at 7:30, we started to do some cleaning. From 9:00 am to 4:00 pm, we tried our best to help the disabled athletes to get ready for their competitors, lead the audience to their seats and keep order. It was not until 12:00 that we had lunch and took a rest, which lasted about an hour. We stopped working at 4:00. Though it was a tiring job, we felt it an honor to serve the disabled friends from all over the world.
