Remarkably,navigation technology has changed very little in the 50 years since its first show.Although modern planes are equipped with computers, pilots lack the ability to“see”the traffic around them and must rely on groundbased controllers for directions. The controllers,in turn, use groundbased radars and radio transmitters to keep planes away from one another.The truth is,your car's global positioning system(GPS) has more precision than the air traffic control technology in use today.
语篇解读:科技日新月异,可是导航技术几十年来几乎停滞不前,飞行员仍然依靠地面控制系统的雷达和无线电传输器为其导航,其精确度甚至比不上车辆上的全球定位系统。
1.The author's attitude towards the present air traffic control technology is ________.
A.positive
B.indifferent
C.negative
D.uncertain
解析:作者态度题。最后一段提到导航技术从诞生之日起到现在几乎没有任何变化,现代化飞机仍然依靠地面控制,而地面控制系统还在借助地面雷达和无线电传输器的帮助为飞机导航,并且当今车辆上的全球定位系统比航空运输控制技术更为准确,由此可判断作者对其持“否定”态度。B项表示“漠不关心的,中立的”,显然不正确。
答案:C
