Traffic lights
Class 8 Grade 6 谭咏珊
Usually,I go to school on foot. It wastes me about 15 minutes on the way. I need to go across two crossings. There is a traffic light which has three colours. Red, yellow and green. Stop and wait at the red light, Slow down at the yellow light, Go at the green light. To arrive school on time and safely, everyone needs to pay attention to the traffic lights.
