How to cross the road safely?      
    First, we must look for a zebra crossing. Then we should look at the traffic lights and wait for the green light. We mustn't cross the road when there is a red light. It's dangerous. To keep safe, we should wait on the pavement and look out for cars and bikes when we can't find a zebra crossing. We must first look left, then right and then left again. In order to let the drivers see us easily, we can cross the road with other people.      
    Only when we follow the rules can we cross the road safely!
