Nowadays, school buses are popular in China. Many students take a school bus to school. It looks like a tourist bus. The underground and common (普通的) buses often take much time. But school buses can save a lot of time. How do children go to school in other countries?
In the US, yellow school buses are a common way for children to get to school. There are about 180,000 school buses in the country. But why are the school buses all yellow? Yellow became the color of school buses in 1939. American educator (教育家) Frank W. Cyr first suggested (建议) it. The color on the buses helped warn other cars: be careful. Black letters on a yellow bus are also easy to see in the early morning.
However, there are not many school buses in the UK. Students from public schools usually take common buses or the underground to school. In Japan, schools are small in cities. So there is no need to use school buses. Children usually walk to school.
