When people go to England, they must learn something about the transportation (交通) there. In England, cars, buses and bikes must keep to the left side of the street. If a person wants to cross a street, he must stop and look at the traffic lights or look both ways down the street. And not looking left first, they look right first. But in China, people will look left first when they need to go across the street. There are few people walking on the street in England, so buses and cars often drive very fast. People need to be very careful when crossing the street.
If visitors(游客)want to go around in London, they should learn to use buses and the underground. First of all, they must know in which direction(方向)they are going and which bus or underground train they must take. At the bus stop they wait for buses to come. As soon as they get on the bus, they must pay for their tickets(票). Some buses there don't tell the stops, so you need to tell the driver where you will get off. Some of the buses have one door only. People get on from one side and get off from another side.
