The Traffic Lights
When you come to my lights, you must look at me. Because I always change hastily(匆忙地).
Keep your eyes on the road, but watch my lights. The colours are the same, both day and night.
Look, I am green. It means you can go. But don't walk too fast or too slow Keep an eye on my lights. It is yellow now. Then I turn red. Don't ask me how.
Red means stop. You must stop and wait. Slow down for the yellow light.
Don't drive through. When the green light is on, you can go. Remember my colours, green, yellow and red.
