Which of the following statements is NOT true of "free flight"
A.Commercial aircraft is guided by GPS.
B.Civilian aircraft are free to move over all territories.
C.Cargo carriers no longer collide with one another.
D.Passenger flights are safe to fly with military aircrafts.
参考答案:B
解析:特定信息的找寻和理解。原文最后部分讲解了什么是“free flight”,其中“pilots of commercial aircraft find their own route”可对应选项a的内容;“stay clear of other aircraft”可与选项C中“no longer collide with one another”对应;并且由上述两点还可推断出选项d的内容是正确的。那么只有选项b的说法与原文不符,因此该选项是正确答案。 注意:1)掌握解释某事物的表达法,如本文中解释free flight时,使用了in which定语从句结构;2)要透过表面解释,根据上下文深入理解某一概念。选项b就是使用了free flight的字面含义来诱导听者。
