    A school busis a kind of bus designed (设计) for student transport: carrying children and teenagers to and from school. So safety(安全) is very important. We should have the same logo (标志) on the school bus and color it yellow so that people can see it far away. People design everything on the bus to keep the students safe, such as, we can pushthe windows easily, the computer can ask the student to wear the seatbelt when the students sit on the seat. There is at least one teacher to look after the students on the bus. When the students get on or get off the bus, the driver should use the traffic lights to tell other cars, then the other cars can wait until the students are safe. When a school bus is on the way, we can know where it is and what it happens on the computer. In a word, we must find ways to make sure the traffic safety is first.
