问题 In the 90’s．people went crazy about wireless．Electronic communications once thought bound pennanently to the world of cables and hard wired connections suddenly were sprung free，and the possibilities seemed endless．Entrenched monopolies would fall，and a new uncabled era would usher in a level of intimate contact that would not only transform business but change human behavior． Such was the view by the end of that groundbreaking decade--the 1 890s．
    To be sure the wild publicity of those days wasn’t all hot air．Marconi’s“magic box”and its contemDoraneous inventions kicked off an era of profound changes，  not the least of which was the advent of broadcasting．So it does seem strange that a century later，the debate once more is about how wireless will change everything．And once again，the noisy confusion is justified Changes are on the way that are arguably as earth shattering as the world’s first wireless transformation．
   Certainlv a huge part of this revolution comes from introducing the most powerful communication tools of our time  Between our mobile phones，our BlackBerries and Treos，and our Wi—Fi(Wireless Fidelitv)computers，we’re always on and always connected  and soon our cars and our appliances will be too．While there has been considerable planning for how people will use these tools and how they，U pay for them，the wonderful reality is that，as with theInternet，much of the action in the wireless worid will uhimatelv emerge from the imaginative twists and turns that are possible when digital technology trumps the analog mindset of telecom companies and government regulators•
   Wi-Fi is itseIf a shining exampie of how wireless innovation can shed the tethers of conventional wisdom．  At one point，  it was assumed that when people wanted to use wireless devices for things other than convrsation．they’d have to rely on the painstakingly drawn，investment-heavy standards adopted by the giant corporations that earn a lot through your monthly phone bill．  But then some researchers came up with a new communications standard exploiting an unlicensed part of the spectrum．It was called 802．1 1．and only later sexed up with the name Wi—Fi．
   Though the range of signal was only some dozens of meters Wi-Fi turned out to be a great way to wirelessly extend an Intemet connection in the home or office  A new class of activist was born：the bandwidth liberator．with a goal of extending free wireless Internet to anyone ventunng within the range of a free hotspot．  Meanwhile，Apple Computer seized on the idea as a consumer solution,others foilowed and now Wi-Fi is as common as the modem once was．
By mentioning Internet．the author means that___________．
选项 A、we are always online and always connected
B、the wireless technology will be popularized as the Internet
C、the Internet will be wireless soon
D、the wireless technology will become a monopoly
答案B
解析 推理判断题。由题干中的Internet定位至第三段末句。该句中“…the wonderful reality is that，as with the Internet，much 0f the action in the wireless world will ultimately e merge from the imagina，tive twists and turns…”讲到正像Internet一样，无线世界的很多行为将最终从虚拟的迂回曲折中脱离出来，发展为现实，由此可以推断B项为答案；原文中第二句讲到“Betlween our mobile phones…we’re always on and always connected”不是指Internet，而且A项中的always过于绝对，排除；文中没有讲到wireless和Internet之间的关系，由as with the Internet可以看出，排除C项；D基，在文中并未提及，故排除。
