When you travel in England, you must be very careful in the street because traffic moves on the left. Before you cross a street, you must look to the right first and then the left. In the morning or evening when people go to work or go home from work, the streets are very busy. Traffic then is the most dangerous. When you take a bus in England, you have to be careful, too. Always remember the traffic move on the left. Have a look first, or you will go wrong way. In many cities of England, there are big buses with the two floors. You can sit on the second floor, from there you can see the city very well. It's very beautiful.
