I went to summer camp on vacation. On the first day, we went to a beautiful beach. It was a sunny and hot day, so we went swimming. The water was warm and we had great fun. Then the next day, we went to the mountains. There were many trees and I really enjoyed them. On the last day, we had a great party. We sang and danced happily. We didn’t want to leave(离开) the friends and the teachers. I hope I can go to summer camp again next year.
