Rocky Lyons was five years old when his mother, Kelly, was driving along the country road with him. He was asleep on the front seat of their truck, with his feet resting on her lap. As his mom drove carefully down the winding country road, she turned onto a narrow bridge. The truck hit a rock and slid off the road. She attempted to bring it back up onto the road by pressing hard on the gas pedal and turning the steering wheel to the left. But Rocky’s foot got caught between her leg and the steering wheel and she lost control of the truck.[ X.JTYJY.COM/]

  The truck fell into a 20-foot ravine（峡谷）. When it hit bottom, Rocky woke up. “What happened, Mama?” he asked. “Our wheels are pointing toward the sky.”

Kelly was seriously wounded and blinded by blood. “I’ll get you out, Mama,” announced Rocky, who had surprisingly escaped injury. He climbed out from under Kelly, slid through the open window and tried to yank（用力拉）his mother out. But she didn’t move.

 “Just let me sleep,” begged Kelly, who was out of consciousness. Rocky insisted, “Mom, you can’t go to sleep.”

Rocky managed to push Kelly out of the truck and told her he’d climb up to the road and stop a car to get help. Fearing that no one would be able to see her little boy in the dark, Kelly refused to let him go alone. Instead they slowly moved up to the road. The pain was so great that Kelly wanted to give up, but Rocky wouldn’t let her.

Rocky kept repeating the inspirational phrase, “I know you can, I know you can.” When they finally reached the road, Rocky broke into tears seeing his mother’s torn face clearly for the first time. Waving his arms and shouting, “Please stop!” the boy stopped a truck. His mother was sent to hospital.

It took 8 hours to rebuild Kelly’s face. She looks quite different today---“I used to have a straight long nose, thin lips and high cheekbones; now I’ve got a flat cheeks and much bigger lips”--- but she has few scars and has recovered from her injuries.

Rocky’s heroics were big news. Everyone was surprised at this little boy’s power. “It’s not like I wanted it to happen,” The boy explained. “ I just did what anyone would have done.” “If it weren’t for Rocky, I’d have died,” said his mother.

Thousands of villages in the developing world have no telephones. They have no money to build telephone systems. A new kind of technology may help change this situation. I t reduces the cost of building and using telephone systems.
Traditional systems use wires to carry electrical signals from one telephone to another. The wires often cost much more than telephones. The new system is based on radio communication. Each telephone sends and receives signals through the air, but not through the wires. This reduces the cost greatly. The radio telephone gets their power from the sun.
Each is connected to a solar equipment that changes the sun’s energy into electricity. A battery stores the electricity until someone needs to make or receive a call. The telephone turns off by itself if the level of power in the battery falls too low. This prevents damage to the system. Each radio telephone is connected to a computer microprocessor. It rewards how many calls are sent and received. It controls the power supply.
The technology needs more study, but its new use of radio equipment sun power and computers may help start telephone ringing in the other parts of the world.
