环保安全高速公路周臻楚高速公路发展迅猛,但频频发生的车祸为人们敲响警钟,因此我想发明环保安全高速公路。这种公路是全封闭的,公路上铺上大摩擦力的高科技粒子,能有效地加快速度而不偏滑。公路还装有安全监测雷达,一旦发现两车有相撞的可能,公路马上感应到并在几秒的时间里, Environmental Protection Expressway Zhou Zhen Chu Expressway has developed rapidly, but the frequent car crash is a wake-up call for people. Therefore, I would like to invent an environmentally-safe expressway. The road is completely enclosed, high-tech particles coated with high friction on the road, can effectively speed up without slippery. Highway is also equipped with safety monitoring radar, once the two cars were found may collide, the road immediately sensed and in a few seconds,
