It was snowing heavily Monday morning. Li Hua was at the bus stop, waited for Bus No. 601 to go to school. After the while, the bus came and she got on it. There are many passengers in the bus. Some were talking but some were looking out of the windows. Suddenly the bus stopped. The driver turned around and said, “Sorry. The bus has been broken down. Please get off and help push the bus.” When we heard this, Li Hua and the other passenger got off the bus. They worked hardly together, pushing the bus slowly backward. Soon the bus was running again. All the passengers were smiling and the sun was shining.
