近年来随着机动车的普及,因违反交通法规而引发的交通事故时有发生,一些以行车安全为情景的中考试题,逐渐成为中考的新热点。此类试题考查的内容与学生现实生活紧密相关,能引导学生关注身边的交通安全,关注物理知识的实际应用,进而体验到物理在社会发展与生活实践中的意义与价值。此类中考试题颇具新意与创意,值得我们加以关注与研究。一、拍摄闯红灯现象【例1】(2011舟山)如图1所示是拍摄机动车闯红灯的工作原理示意图,光控开关接收到红灯发出的光会自动闭合,压力开关受到机动车的压力会闭合,摄像系统在电路接通时
In recent years, with the popularization of motor vehicles, traffic accidents caused by violation of traffic regulations have occurred from time to time. Some of the senior high school entrance examination examinations with driving safety as the scene gradually become new hot spots in the examination. The contents of exam questions are closely related to students’ real life, which can guide students to pay attention to the traffic safety around them, pay attention to the practical application of physical knowledge, and then experience the significance and value of physics in social development and life practice. Such examination questions quite innovative and creative, it is worth our attention and research. First, shoot the red light phenomenon [Example 1] (Zhoushan in 2011) is shown in Figure 1 is shooting a motor vehicle running a red light schematic diagram of the principle, the light control switch receives the red light emitted automatically closed, the pressure switch by the vehicle pressure will Closed, camera system when the circuit is connected
