In China, most of the students go to school by car or by bus. If the school is not far, they can walk to school every day. Few students are late for school. But things are different in other countries. In many Western countries, the students live far from their schools. They go to school in different ways. Many of them go to school by metro. In some cities, there are double-deck buses. This kind of bus has two floors and it can carry more people. So some students can take a double-deck bus to school. In some cold countries, it often snows. The students in town may take a school bus. But the students in villages have to go by sledge （雪棉） because there is snow everywhere. Sometimes the students may be late for school. If it snows heavily, the students can only study at home. Guess, in which country, the students may go to school by boat?
