疲劳驾驶每年会给数万家庭带来不幸，如果能采取措施防止这样的情况发生无疑能造福世人。本文为同学们整理了相关的托福阅读材料之防瞌睡监视器，供各位考生参考。

　　German scientists have invented a device designed to prevent motorists from falling asleep at the wheel which could save 300,000 lives a year around the world. The system devised at the Fraunhofer Institute for Digital Media Technology involves tiny cameras that monitor eye movements which trigger an alarm when drivers seem about to nod off.

　　德国科学家近日发明一种能够“防止司机开车时瞌睡”的监视器，据悉，这一新发明一旦问世，每年可以“拯救”30万民众的生命。监视器囊括了一个“微型摄像头”用来观察司机眼部活动情况，司机一旦打盹，眼皮的活动会通过传感器告诉设备，并发出尖锐的警报声。

　　Professor Peter Husar of the institute said: What we have developed is a small modular system with its own hardware and programmes on board, so that the line of vision is computed directly within the camera itself.

　　发明此设备的教授Peter说，该设备属于自带存储命令的模块化系统，司机“视线”运动情况将会受到系统中的微型摄像头监视。
