Every day some people are killed while they are crossing the roads. Most of these people are old and children. Old people are often killed because they can’t see or hear very well. Children are killed because they are not careful. They forget to look anlisten before they cross the roads. A car or a bus can’t stop quickly.
If a car is going very fast, it will go many before it stops. Some people do not always understand this. They think a car can stop in one meter. It is hard to know fast a car is moving. The only way to cross the road safely(安全) is to look both ways, right and left. Then if the roads are empty(空的), you can cross them.
