On Christmas Eve, the evening before Christmas Day, children always put a stocking(长筒袜) at the end of their beds. Their parents often tell them that Santa will bring gifts for the good children. When the children sleep in their beds, Santa will climb down the chimney(烟囱)into the house and fill the stockings with Christmas gifts.
In fact, children's fathers will put on red hats and red clothes. They will put the gifts into the stockings or under the Christmas trees.
Look! This is a picture. It is about Jenny's birthday. Her birthday is on May 25. On that day last year, she invited her friends to her house. Li Ming, Tom and I went to her house. We had a very good time. Before eating the birthday cake, we sang the birthday song for Jenny. She was very happy. And we were happy, too. After lunch, we went out to play in the park. We had fun all day.
