繁忙的马路上,每天车水马龙,人来人往。可是,当路口那个看上去呆头呆脑的家伙眼睛“红了”的时候,所有人都得乖乖地听从它的指令,停下车子、放慢脚步来耐心等候。不过,城市交通的井然有序可少不了这个家伙的大力协助啊!它就是我们城市的交通“指挥家”——交通灯。随着城市里的居民越来越多,马路上的汽车也越来越多,交通灯的任务也就更加繁重艰巨了。为了迎接新挑战,这位交通“指挥家”不断改进自己,使自己越来越环保,功能越来越强大。 Busy streets, busy every day, coming and going. However, when the dull-looking guy at the junction had his eyes “red”, everyone obeyed it obediently, stopping the car and slowing down to wait patiently. However, the well-organized urban traffic can be greatly assisted by this guy! It is our city traffic “conductor ” - traffic light. As more and more residents in the city, more and more cars on the road, the task of traffic lights will be more arduous and arduous. In order to meet the new challenges, the traffic “conductor” constantly improves himself and makes himself more and more environmentally friendly and more powerful.
