It is hard to say that a telephone is just a telephone anymore. Not only does it let you hear Grandma's voice from miles away clearer than ever before, but it is providing even more important information services to its users. By the year 2000, American householders will rely on the telephone system for shopping, computing, playing the stock market, making airline reservations, and watching television. The lives of heart patients may depend on telephones with on line electronic systems altering their doctors to emergencies. This is in addition to American business managers who currently rely on their telephones for sales orders, inventory control, banking, video image transmission, and many other tasks.

New technologies, such as advanced computing and fiber optics, make telecommunications services cheap and quick. In addition, since the breakup of AT&T, the competition spawned (引起) among many phone companies has emphasized price changes and introduced innovative services.

But despite the stimulus to provide commercial benefits during normal operation, one essential ingredient is missing—the incentive to design for emergency preparedness in the event of disaster. The telephone system is improving its ability to respond to some emergencies such as wartime attack, but is not prepared to handle terrorism, natural disasters, fires or accidents.

Before divestiture (解体) AT&T operated a national emergency center that coordinated all procedures during a disaster. Today, in lieu of the previous AT&T center, a government agency—the National Communications System (NCS) —operates the National Coordinating Center to address disasters related to telecommunications. In addition, the numerous phone companies and large communications suppliers have developed mechanisms of their own to respond to limited emergency situations, but massive emergencies are beyond their capabilities.

  What comes into your mind when you think about robots? Do you imagine armies of evil metal monsters planning to take over the world? Or, perhaps of mechanical men who have been created as guards or soldiers by a mad genius? Or maybe you think of man- like robots who act, think, and look like human beings. In fact robots like these have more to do with science fiction films than with real life. In the real world robots are machines that do jobs which otherwise have to be done by people. Robots either operate by themselves or under the control of a person.

  In a car factory, for example, robot machinery can put together and paint car bodies. On the sea bed remotecontrolled(遥控)underwater machines with mechanical arms can perform tasks too difficult for divers. Robot spacecraft can explore the solar system and send back information about planets and stars.

  Many robots have computer brains. Some robots are fitted with cameras , sensors, and microphones which enable them to see, to feel, and to hear. And some robots can even produce electronic speech.

  All this does not mean that a robot can think and behave like a human being. Present day robots have to be programmed with a good deal of information before they can carry out even simple tasks.

 44.Robots in real life________.

  A. can behave like human beings   B. have the ability to control the world
