Traffic lights
Traffic lights are important tools (工具) to keep people safe on the road. They use three colours: red, yellow, and green. Each colour has a special (特别的) meaning.
— Red means "Stop and wait!" Never cross the road when the light is red, even if (即使) you are in a hurry.
— Yellow means "Slow down and prepare (准备) to stop." It warns (提醒) you that the light is about to turn red.
— Green means "Go, but check (查看) carefully first." Always look left and right before crossing, even if the light is green. Because some cars might turn.
1. What should you do at the red traffic light?
2. What does a yellow light tell drivers and pedestrians (行人)?
3. Why do we always look both ways even if the light is green?
