    In our city there are more and more cars and buses on the roads. Many people drive to work .First, it's good to have a car. You needn't to wait for the bus. You can go to work on time. Then ,there are many busy roads in the city . Can you drive safely? Traffic lights are very important. You must look at the traffic lights and wait for the green man. If someone is crossing the road, you must stop your car and look carefully. We must follow the rules and stay safe on the road.

    The traffic lights are the same in every country. There are always three lights: red, yellow and green. Red means "stop" Yellow means "Wait", and green means "Go". In most parts of China, drivers drive on the right side of the road. In the US, drivers drive on the right side too. In England and Australia, however, drivers drive on the left side of the road. If you go by car, by bike or on foot, you must know the traffic rules.

    The traffic rule in England is different from that in China. When you are in England, you must be very careful on the street because the traffic drives on the left. You must look at the right first and then the left. If the traffic lights are red, the traffic must stop. Then the people can cross the road on foot. If the traffic lights are green, the traffic can go. People mustn't cross on foot.

    When you go by bus in England, you have to be careful too. Always remember the traffic moves on the left. You mustn't 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 very well. It's very interesting.
