How can we lessen(减少) traffic accidents? All of us m   obey(遵守) the traffic rules. For the d    , they shouldn’t drive too fast. If they drive too fast, it will be very d     to stop the cars in a very short time. For the pedestrians(行人), it’s very important to be careful when they are w     on the road. Therefore, when we walk a     the road, we must try to walk along the pavements. We must stop and look both ways b     crossing the road. Look left first, next look right, then look left again. O     when we are sure that the road is clear, we can cross it. The r   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. We teens should try to h     children, old people or blind people to cross the road, and n   play in the street.
