When you are in England,you must be very careful in the street because the traffic drives on the left. Before you cross a street,you must look to the right first and then the left. If the traffic lights are red,the traffic must stop. The people on foot can cross the road carefully. If the traffic lights are green,the traffic can go. The people on foot must not cross. In the morning and in the evening when people go to or come from work,the streets are very busy.
When you go by bus in England,you have to be careful,too. Always remember the traffic moves on the left.So you must be careful. Have a look first or you will go the wrong way. In many English cities，there are big buses with two floors. You can sit on the second floor. From there you can see the city well. It is very interesting.
