     When I was in Grade Four, Mr Stamps took us to a place called Camp

Noria to go camping.

     When we arrived at the camping, we took a walk in the forest. Then we

had a difficult project: to build a small house in the forest After the project

was finished the sky was dark, then We return to the campsite to have supper.

     We roasted (烤) hotdogs on the bonfire(篝火). The botdogs smelled good! Some of the other food was not that good. After supper everybody played a game of tag(捉人游戏).  It was very cold at night and the next morning

everybody was awake very early.

     Around noon time, the sun rose up. We took turns riding a small horse.

When starting to ride it, I was scared, but after being on it for some time, I

felt that it was fun. In the afternoon we went to row canoes（划独木舟).

Since this was my first time doing these activities, I felt very excited.

     On the third day we returned home. I hope to go back there next year.
