I'm a student. I like reding books. Every week I go to the library, Usually I go there by bus. I know the traffic lights are the same in every country. There are three light: red, yellow and green. Red means "Stop and wait". Yellow means "Slow down and stop". Green means "Go". But the traffic rules are different in some countries. In China and the USA, people drive on the right side of the road. But in the UK and Australia, people drive on the left side of the road. We should remember (记住) the traffic rules. Don't go the wrong (错误的) way.
