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 sure to rise dramatically. 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 diary of tremendous personal value.
In Cambridge, we’re already working on millimeter-sguare(平方毫米)computing and sensing devices that can be linked to the Internet through the radio network This sort of connectivity will expand dramatically as tiny 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.
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 greatly. 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 communications network that completely does away with towers and poles.
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 an optical-fiber audio-video link; we’ll be able to sit down "together" to eat.
Cars are an interesting IT-platform because they have big batteries and lots of so far unconnected digital devices. Soon each one will be on the Internet so your children can play games while you’re traveling and your partner can deal with their email. And every lamppost could be on the Internet too—each one with sensors to monitor light, pollution, air quality and traffic flow.
By saying that he takes many images of his children, the author wants to _____.
选项
A、show his great interest in photography
B、compare his own life with his children’s
C、display the influence of communications on life
D、demonstrate the ease of enjoying life electronically
答案
C
解析
本题考查例子与中心思想的关系。第1段的第1句可被视为主题句,其他句子是对该主题句的具体举例说明。例子总是与中心思想密切相关的,因此,本段的例子是为了说明通讯技术对人们生活的影响,即选项C。本题最具干扰性的是选项D,本段第2句中也提到record your life electronically,但本段是为了说明通讯技术的重要性,不是为了说明ease(简易性),因此,选项D不正确。
