I took part in (参加) the Bird-watching Summer Camp last year. Mr Green is a famous bird-watcher. After breakfast, he told us how to watch a bird. At 10:30, we left the camp for climbing the mountain. Mr Green gave everyone a telescope (望远镜). Then he gave each of us a sandwich, an apple and a bottle of water for lunch. We ate lunch on the mountain. It was very hot at noon. We all put on the caps, but Tom didn't. He enjoyed watching the birds. He drew many birds on his notebook. Six hours later, we went back to the camp.
The birds are lovely. We all like the birds. We should protect (保护) the environment (环境).
