问题                     Cellphones Aloft:The Inevitable Is Closer
    The day may finally be coming when you will be allowed to make calls on your own cellphone from an airliner. Trouble is, so will the passengers sitting on either side of you, and in front and in back of you, as well.
    Federal regulators plan next week to begin considering rules that would end the official ban on cellphone use on commercial flights. Technical challenges and safety questions remain. But if the ban is lifted, one of the last protections of relative social silence would disappear, forcing strangers to work out the rough manners of involuntary eavesdropping in a confined space.
    "For some people, the idea of being able to pick up their phone is going to be liberating; for some it’s going to drive them crazy," said Addison Schonland, a travel industry consultant at the Innovation Analysis Group in La Jolla, California. "Can you imagine 200 people having a conversation at once? There’s going to be a big market for noise-canceling headphones."
    The always-on-the-road business travelers may become the worst offenders, predicted Roger Entner, a telecommunications analyst with the Yankee Group and a frequent flier. "Businessmen will now compete with kids for the title of most annoying in the airplane," Mr. Entner said.
    It may be years before cellphones become widely used in the skies Conventional cellphones, besides raising concerns about interfering with cockpit communications, typically do not work at altitudes above 10,000 feet or so.
    But some airlines have already begun their own tests of technology meant to make cellphone use feasible at 35,000 feet. They know that the seatback phones they now oiler, costing $ 1.99 a minute or more, have never really caught on.
    The airlines also know that, while illegal, surreptitious cellphone use at lower altitudes is already common. Airline attendants have caught some passengers using cellphones in airplane lavatories, and others have been spotted huddled in their seats, whispering into their cupped hands.
    A major federal effort to revisit the rules will begin next Wednesday at a Federal Communications Commission meeting, where the agency is expected to approve two measures. One, an order that is expected to be adopted, would try to introduce more price competition among phone companies to offer telephone and high-speed Internet services from the seatback and end-of-aisle phones that are now on many planes. The second measure will begin the regulatory process of considering whether there are technical solutions to some of the current obstacles to passengers’ using their own mobile phones on planes. [br] It can be inferred from the passage that______.
选项 A、technical problems remain the largest obstacle in using phones in skies
B、people seldom use seatback phones in planes because of the quality
C、airlines might be the first to solve the high-altitude problem
D、some people might stop traveling by air because of involuntary eavesdropping
答案 A
解析 本题考查推理引申。文章第二段第二句指出，技术问题和安全问题依然存在；第五段指出，传统的手机干扰通信并无法在高空使用；文章的最后一句话指出，联邦通信委员会的第二个措施就是考虑是否可以从技术上解决乘客使用手机的障碍，因此，纵观全篇，技术性问题依然是飞机上使用手机的最大障碍，[A]为正确选项。[B]选项中提到的旅客很少使用飞机座位上的电话，原因是高昂的话费，而不是通话质量。航空公司已经着手解决高空中使用手机的技术性问题，但是文中没有提及他们可能最先找到答案，因此[C]选项不正确。人们对于被迫偷听也许会很生气，但是并不说明可能就此不坐飞机旅行，因此也排除[D]。
