It's very important for us to keep safe on the street.We should obey the traffic rules.When the red light is on,we must stop and we are not allowed to go on walking.It's safe to cross the road when the light is green.When we want to cross the road,we'd etter look left and right to make sure we are safe.Don't forget that it's very dangerous to play on the strees.
将street改为road就可以了
