单选题One of the qualities that most people admire in others is the willingness to admit one's mistakes. (79) It is extremely hard sometimes to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong, and you were right about that." I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a grocery store in the neighborhood where I grew up, and he asked me if ! remembered the egg cartons. Then he related an incident and I began to remember vaguely the incident he was describing. I was about eight years old at the time, and I had gone into the store with my mother to do the weekly grocery shopping. On that particular clue, I must have found my way to the dairy food department where the incident took place. (80) There must have been a special sale on eggs that day because there was an impressive display of eggs in dozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together; so I went to work. The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees inspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was the culprit (罪犯). He severely scolded me and wanted me to pay for any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not.

单选题Imagine you're at a party full of strangers. You're nervous. Who are these people? How do you start a conversation? Fortunately, you've got a thing that sends out energy at tiny chips in everyone's name tag (标签). The chips send back name, job, hobbies, and the time available for meeting—whatever. Making new friends becomes simple. This hasn't quite happened in real life. But the world is already experiencing a revolution using RFID technology. An RFID tag with a tiny chip can be fixed in a product, under your pet's skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device (装置), that sends out energy (for example, radio waves) that starts up the tag immediately. Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient's medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm. Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler. RFID tags are a small part of this phenomenon. "The world is going to be a loosely coupled set of individual small devices, connected wirelessly," predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here's a wild guess.. Not for buying milk.

单选题When someone has money (56) he wants to put in a safe place, he (57) takes it to a bank.

All the windows and doors were wired to set (60) the burglar alarms if anyone tried to (61) his way in. The vaults where he money was kept had huge, steel doors with (62) locks.

The (73) and burglar alarms are still there, but they are (74) noticeable than they (75) to be.
