近年来,有关“STS”(科学-技术-社会)的试题经常在高考试卷中出现.这类试题一般具有“高起点、低落点”的特点,有利于考查学生的综合素质. 一、与交通事故相联系的高考题例1(2002年春季北京高考题)在高速公路上发生了一起交通事故,一辆质量为1500kg向南行驶的长途客车迎面撞上了一辆质量为3000kg向北行驶的卡车,碰后两辆车接在一起,并向南滑行了一段距离后停止根据测速仪的测定,长途客车碰前以20m/s的速率行驶,由此可判断卡车碰前的行驶速率( )
In recent years, test questions related to “STS” (Science-Technology-Society) have often appeared in the high test papers. These test questions generally have the characteristics of “high starting point, low drop point” and are conducive to examining the overall quality of students. The accident-related college entrance examination question 1 (Beijing’s college entrance exam in spring 2002) involved a traffic accident on the expressway. A coach with a mass of 1500 kg traveling south hit a 3,000-kilogram northbound vehicle. In the truck, after the collision, the two vehicles were connected together and taxied a certain distance to the south and stopped based on the determination of the speedometer. The long-distance bus was driven at a speed of 20m/s before it could determine the driving speed of the truck ().
