Yesterday was September 10th. It was Teachers' Day. We bought some flowers and cards for our teachers. We put them in the teachers' office. We were grateful(感激的)to our teachers for their hard work. Our teachers were very happy. In the afternoon we had a party in our school hall. Many students and teachers gave wonderful performances(表演)at the party. We sang and danced happily with our teachers. All the teachers and students had a good time.
