Henry is a twelve-year-old boy. He doesn't like rules(规则). It's nine thirty in the evening. He's sleeping and dreaming. In his dream, he goes to the street. There are many people in the street. Two boys are running. A car is coming. It is very dangerous! A girl is riding a bike when the traffic light is red. It is not safe(安全的). Many children are playing near the street. Some are playing football and some are skipping rope. Some children are swimming in the lake. That is dangerous. "We really need rules, " Henry thinks.
