36 The Traffic Lights This is a street crossing. There are traffic lights at each corner. Drivers must watch the lights carefully. When there is a green light, the cars may go on. When there is a red light, the cars must stop. They must wait until the red light changes to green. Then they can go on. Sometimes, the cars want to make a right turn or a left turn. They can make a right turn when the light is green or red. But they must wait until the green light is shining if they want to turn left. Some people are color-blind. They cannot see the difference between red and green. These people must not drive, or else there will be accidents. We must keep our streets safe. 这是一个十字路口。每一个街道拐角处都有红绿灯；司机们必须认真看指示灯。 当绿灯亮起时，车辆可以通行。当红灯亮起时，车辆必须停止。他们必须等到红灯变成绿灯才能继续行使。有时车辆想要左转或右转。无论是红灯还是绿灯时，他们都可以右转。但如果他们想要左转，就一定要等到绿灯亮时。 有些人是色盲。他们无法分辨红绿灯。这些人绝对不能开车，否则会发生车祸。我们必须保证道路的安全。 crossing ['krɒsɪŋ] n．十字路口 traffic lights ['træfɪk laɪtz] 交通指示灯 until [ən'tɪl] conj. 直到……才 color-blind ['kʌlə blaɪnd] adj. 色盲的 accident ['æksɪd(ə)nt] n．事故 蟋蟀教育微信：13661633986 蟋蟀教育微博：蟋蟀教育科技
