      People are often killed while crossing the road. Most of these people are old people and children. Old

people are often killed because they usually can not see or hear very well. Children are often killed because

they are not careful. They have to look and listen before they cross the road.

     A car, truck or bus can not stop very quickly. If the vehicle (汽车) is going very fast, it will travel many

meters before it stops. People don't always understand this. They think a car can stop within a few meters.

The faster a car is traveling, the longer it takes to stop. It is very difficult for a person to know how far a car

is traveling. 

     The only safe way to cross the road is to look both ways, right and left. Then if the road is clear, it is

safe to cross. The right way to cross the road is to walk quickly. It is not safe to run. If people run across

the road, they may fall down.
