Shockingly,today only 13 percent do! In North America,most students go to school on the school bus.Some students

also walk or ride bikes to school. In other parts of the world,things are different. In Japan, most students take trains to

school,although others also walk or ride their bikes.In China , it depends on where you are.In big cities,students usually ride bikes to school or take buses.And in places where there are rivers and lakes,like Hongshanhu and Kaishandao,
