     I had a summer camp with my classmates for the first time last year. Early in the morning, we gathered at

the bus station. After saying goodbye to our parents, we got on the bus. It took us more than five hours to

arrive at the campground. We got off the buses cheerfully. We jumped and ran all over the place, laughing and

shouting. It was the first time for us to be away form our parents. Some of us started to feel homesick (想家的). However, when the night party and dances began, the homesickness was gone. The next day, everybody

rushed to the boating class. At first, my friends and I worked hard, but the boat wouldn't listen to us and kept

going round and round. Then the teacher taught us how to work together. After many tries (尝试), we did

much better. Swimming class was my favorite. It was about the hottest time of a day and the best time to stay

in the cool water. The swimming teacher was a funny man, and during the class he often made us laugh

happily. During the week I learned a lot of things and made new friends. I also learned how to take care of

myself.
