e 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-square (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’ be able to sit down “together” ll
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.

答案： 1．[C]主旨大意题。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。 2．[B]观点态度题。从第 2 段最后一句中的 imagine 一词，及最后说到通讯粉尘的用 处的词句可以看出，作者对通讯粉尘是表示认同的，认为它发挥的功能很神奇，即选项 B。 选项 C 和 D 在文中也有提到，但都不是作者的目的。 3．[C]推理判断题。本题考查复合句及 do away with 的理解。第 3 段最后一句的定语 从句表明通讯网络以后可以不依靠发射塔或电线杆了， 换句话说， 低轨道卫星在功能上可以 代替发射塔或电线杆，因此 C 是正确选项。选项 A 是最具干扰性的，因为“成本降低”这个 说法在本段一开头就提到，但是文中事实上并未提到使用低轨道卫星能降低通讯网络的成 本，相反，正因为成本降低了，才使得使用低轨道卫星成为可能，因此选项 A 颠倒了因果关 系。 4．[A]推理判断题。本题考查特殊标点符号的理解。在第 4 段最后一句中，together 加了引号， 表明他们并不是真的能一起吃饭， 只是能看到彼此吃饭以及彼此谈话， 由此可见， 选项 A 正确， 而选项 B 也可因此排除。 选项 C 中的 free of charge 与该段第 l 句中的 almost free 不符。选项 D 与该段第 2 句的 have fixed links 不符。 5．[B]词义推断题。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 lamppost could 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。
