    Today is a special day for me. Because it's my last Children's Day. We're going to graduate(毕业) from the primary school. We had a big party in our classroom. Girls cleaned the room. Boys decorated(装饰)the room with pictures and balloons. There were many drinks，food，fruits and gifts. We were all very excited.
    We had a good time in the party. Lucy played the guitar. John did a kung fu show. We sang，danced and played with each other. We ate the cakes and took many pictures. We didn't want to say goodbye to our friends or teachers. How time flies!
