问题     It’s 10 pm. You may not know where your child is, but the chip does.
    The chip will also know if your child has fallen and needs immediate help. Once doctors arrive, the chip will also be able to tell them which drugs are not suitable for little Johnny or Janie. At the hospital, the chip will tell doctors his or her complete medical history. And of course, when you arrive to pick up your child, settling the hospital bill with your health insurance policy will be a simple matter of waving your own chip— the one embedded in your hand.
    To some, this may sound unbelievable. But the technology for such chips is no longer the stuff of science fiction. And it may soon offer many other benefits besides locating lost children or elderly patients. It could be used as credit cards and people won’t have to carry wallets anymore.
On the other hand, some are already wondering what this sort of technology may do to the sense of personal privacy and liberty.
    "Any technology of this kind could result in abuse of personal privacy," says Lee Tien, senior staff attorney for the Electronic Frontier Foundation. "If a kid can be tracked, do you want other people to be able to track your kid? It’s a double-edged sword."
    Applied Digital Solutions, Inc. in Palm Beach, Florida, says it has recently applied to the Food and Drug Administration for permission to begin testing its device in humans. About the size of a grain of rice, the microchip can be encoded (编码) with bits of information and embedded in humans under a layer of skin. When scanned by a nearby reader, the embedded chip gives the data.
    Most embedded chip designs are so-called passive chips, which give information only when scanned by a nearby reader. But active chips—such as the proposed Digital Angel of the future—will give out information all the time. And that means designers will have to develop some sort of power source that can provide a continuous source of energy, yet be small enough to be embedded with the chips.
    In addition to technical problems, many suspect that all sorts of legal and privacy issues would have to be cleared as well.
By using the example in the first two paragraphs, the author wants to tell us that______.
选项 A、chips are usually used to locate lost children
B、chips are more convenient than credit cards
C、chips will soon be useful in many aspects of daily lives
D、chips will bring out the issue of abuse of personal privacy
答案C
解析 主旨大意题。本题考查例子与观点的关系。第3段是对前两段的总结及进一步的阐述，因此，本段就是前两段想要说明的观点。选项A和B只是对例子中某些细节的陈述，不能总括例子的中心思想。这两段的例子说的都是芯片的好处，因此与选项D所说的问题不相关。
