     I had a summer camp with my classmates last year.

     Early in the morning, we gathered at the bus station. After saying goodbye to our parents, we got on the bus. ①It

took us more than two hours to arrive at the campground. 

     We got off the bus cheerfully, laughing and shouting; we jumped and ran all over the place. It was the first time for

us to be away from the parents. Some of us started to feel homesick(想家). However, when the night party and dances

began, the homesick was gone.

     The next day,②everybody rushed to the boating class, hoping to be at the head of the others. 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, 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 new things and made many new friends. I also learned how to take care of myself.
