B

On a small farm in Mexico, there are no schools.  A bus is a school! The driver of the bus is the teacher! It is a school bus, but it does not take the children to school. It just goes round from place, and it sometimes comes to this farm. The bus will stay here for three months. The farmers call it a school on wheels(轮子).

Each time when the bus comes, the farmers will come running to it, shouting and laughing. They warmly welcome the school bus!

When the bus is on the farm in the morning, the teacher teaches the small children. In the afternoon, the bigger children come to have their lessons because they must work in the morning. At night, the fathers and mothers come to have their lessons and hope that some day they can have a real school on the farm.
