How time flies! It's time to say goodbye!

Thank you, my dear friends. We really changed a lot in six years. Before, we were short and small. Now, we are tall and big. We studied and played together. We helped each other. We are brothers and sisters. We had a lot of fun.

Thank you, my friendly teachers. Sometimes you were strict, but your classes were so much fun. We had parties together. We visited Nanxi River together. We had happy days.

Thank you, my lovely school. We learned and enjoyed every day. We drew pictures in the art room. We read books in the library. We sang and danced in the music room. We jumped and ran on the playground. It was so happy to study here.

In the past six years, we had so many special memories(回忆).
