     Every year thousands of people get hurt or die when they are crossing the road. Most of these people are

old people and children. Old people often get hurt or die because they can't see or hear very well. Children

usually meet with accidents because of their carelessness. They forget to look and listen before they cross the

road.

     How can we lessen (减少) traffic accidents? All of us must obey the traffic rules. For the drivers, they

shouldn't drive too fast. If they drive too fast, it will be very difficult to stop the cars in a very short time. For

the pedestrians (行人), it's very important to be careful when they are walking on the road. Therefore, when

we walk across the road, we must try to walk along the pavements. We must stop and look both ways before

crossing the road. Look left first, next look right, and then look left again. Only when we are sure that the road

is clear can we cross it. The right way to cross the road is to walk quickly. It's not safe to run. If people run

across the road, they may fall down. Teens should try to help children, old people or blind people to cross the

road, and never play in the street.
