作业精灵老师示例：
It's going to be Chinese New Year. I'm very happy. Before Chinese New
Year, we make dumplings at home and buy a lot of things in the supermarket.
On Chinese New Year's Eve, we sit around the table and have a big family
dinner. On the first day of Chinese New Year, my mother gives me a red packet
and we light firecrackers. After lunch, my parents take me to watch the Lion
Dance. In the evening, we watch fireworks together. On the second day of
Chinese New Year, we visit friends and relatives. I like Chinese New Year.
