Once,there was a bus driver in a small village.His job was to take children to school in his red bus.Usually,he would stop at the village center to pick up the children.Then he would drive them to a nearby village a few kilometers away,as their own village had no school.
Each trip usually cost 99 cents.However,one day,the bus driver made a special decision.He decided not to charge（收费）the children anything at all,even though his family was living a hard life as well.Many of the children\’s parents were jobless,so it was hard for them to save money.He believed this was a good way to help them.
The kind bus driver drove the kids to school every day,sunny or cloudy,rainy or snowy.He made sure they got there safely and on time.But after a few months,the bus wheels became worn out.Moving around became very difficult.Seeing the bus couldn\’t work well,all the moms and dads in the village decided to collect enough money to repair the red bus.
After the repairs,the red bus looked as good as new with a fresh coat of paint.It also got new wheels,so it could keep working for a long time.
