How do you get to school every day? By bike, bus or car? In Chongqing, there will be 3,000 new school buses on the street by the end of this year. These school buses look just like tlic American school buses: yellow with a big nose.
In February 2010, the Chinese government announced the first standards (标淮）for school bus safety. Since then, more yellow school buses can be seen on the street.
In China, besides the bus driver, there should be an adult on the school bus to watch the students. If there are more than 40 students, two adults are needed. The students usually rest or read books on the school bus.
In America, yellow school buses are very popular. There are about 480,000 school buses in the country. The older kids sit in the back of the bus. The younger kids sit in the front. They usually listen to music, talk on their phones or just sleep. The only adult on the bus is the driver.
The school bus is important in students’ everyday lives. It can keep children safe. Usually a child is much safer going to school by school bus than any other way. It can also help the environment. A school bus saves a lot of gas (汽油）because it can carry a lot of people.
