2016年8月17日GRE逻辑机经
题目
Avionics is a portmanteau word meaning “aviation electronics.” It is a term that has evolved over the last 40 years as airplane instrumentation has evolved from mostly mechanical to largely electronic. Today, avionics makes up the large part of the cost of any aircraft. Guidance and navigation systems are integrated. Communications includes public address systems for communicating with passengers, intercoms for communicating with flight crews, and radio or SatCom for communicating with ground personnel. In addition, planes today have weather radar, lightning detectors, automatic flight control systems, and collision-avoidance systems. All of these systems must work in tandem in order for the plane to fly.
Which of the following inferences about avionics is best supported by the passage?
A. Within a decade, passenger planes will take off and land without human intervention.
B. Soon passenger planes will include features that now appear only on military planes.
C. Just 40 years ago, there were no electronic devices on passenger airplanes.
D. As avionics becomes more common, the cost of manufacturing planes will decrease.
E. A glitch in a plane's electrical system may be the greatest danger in flight today.
参考答案：E.
文章大意：航空设备在过去40年的发展过程中，逐渐由大部分为航空机械设备发展成大部分为航空电子设备。故如果出现电子差错，可能导致大的危险，E选项正确。
