(1) The communications explosion is on the scale of the rail, automobile or telephone revolution. Very soon you’ll be able to record your entire life electronically—anything a microphone or a camera can sense you’ll be able to store. In particular, the number of images a person captures in a lifetime is set to rise exponentially. The thousand images a year I take of my children on a digital camera are all precious to me. In a generation’s time, my children’s children will have total image documentation of their entire lives—a visual log of tremendous personal value.
(2) By then we’ll be wrestling with another question; how we control all the electronic devices connected to the Internet: trillions of PCs, laptops, palmpilots, cell phones and other gadgets. In Cambridge, we’re already working on millimeter-square computing and sensing devices that can be linked to the Internet through the radio net work. This sort of connectivity will expand dramatically as microscopic communications devices become dirt-cheap and multiply. Just imagine what the paint on the wall could do if it had this sort of communications dust in it: change color, play music, show movies or even speak to you.
(3) Falling costs raise other possibilities too. Because launching space vehicles is about to become very much cheaper, the number of satellites is likely to go up exponentially. There’s lots of space up there so we could have millions of them. And if you have millions of low-orbit satellites you can establish a global commumcations network that completely does away with towers and masts. If the satellites worked on the cellular principle so you got spatial reuse of frequencies, system capacity would be amazing.
(4) Speech is so flexible that I expect voice communication to become almost free eventually: you’ll pay just a monthly fixed charge and be able to make as many calls as you want. By then people will also have fixed links with business contacts, friends and relatives. One day I anticipate being able to keep in touch with my family in Poland on a fibreoptic audio-video link; we’ll be able to have a little ceremony at supper-time, open the curtains and sit down "together" to eat.
(5) Cars are an interesting IT-platform because they have big batteries and lots of so far unconnected digital devices. Soon each one will be an entity on the Internet so your children can play interactive games while you’re traveling and your partner can deal with their e-mail. And every lamppost could be on the Internet too—each one with sensors to monitor light, pollution, air quality and traffic flow.
Which of the following is INCORRECT according to the passage?
选项
A、Voice communication would become almost free eventually.
B、Your children can play interactive games in the car in the future.
C、Spatial reuse of frequencies will be in trouble in the future.
D、Lamppost would be able to monitor pollution and air flow.
答案
C
解析
推断题。文章第三段第五句指出“If the satellites worked on the cellular principle so you got spatial reuse of frequencies,system capacity would be amazing.”,所以[C]与原文内容不符,故为答案。[A]、[B]和[D]均可在文中第四、五段找到原句,故排除。
