| In Britain, cars, buses and bikes must keep to the left of the street. If a person wants to cross the street, he must be very careful. Before he crosses a street, he has to stop and look to the right side first and then the left. But in China, we look to the left first. When visitors are in London, they should learn how to take buses and underground trains (地铁). The most important of all, they must know in which direction they are going and which bus or underground train they should take. At the bus stop they should wait for their buses to come. As soon as they get on a bus, they must pay their fares (车费). | |
