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.
The phrase "each one"(Line 2, Para. 5)can be best replaced by _____.
选项
A、each digital device
B、each car
C、each battery
D、each person
答案
B
解析
本题考查代词one的理解。代词通常指代上文提到过的事物,上文提到过汽车(选项B)、电池(选项C)和数字设备(选项A),要推断one指代哪一个,可从最后一段的最后一句中的“And every lamppostcould be on the Internet too”这一表示递进的结构推断出one应指与lamppost相似的整体,而不指某个部分设备,因此,B为正确选项。
