    Traffic lights are very important for us. I think you can know this. They can help buses or cars to go regularly(有规律地) on the roads. But do you know how they were born?

Morgan is the father of traffic lights. He was born in the U.S.A. His family was poor. He left school at the age of 14. He was smart. He always looked for better ways to do things, and he liked to make new things. At that time, every American wanted to have a car. The streets were full of cars. The traffic was bad. “Why not put three lights at each corner? They should be red, green and yellow,” Morgan said. “Let them tell cars to go or stop.” So he made a timer(定时器) to change the lights. Now we have traffic lights.
