Across the English Channel To swim across the English Channel takes at least nine hours. It’s a hard work and it makes you short of breath. To fly over the Channel takes only twenty minutes (as only as you’re not held up at the airport), but it’s an expensive way to travel. You can travel by hovercraft if you don’t mind the noise, and that takes forty minutes. Otherwise you can go by boat, if you dreams of being able to drive to France in his own car. "Not possible", you say. Well wait a minute. People are once again considering the idea of a Channel tunnel or bridge. This time, the Greater London Council is looking into the possibility of building a Channel link straight to London. A bridge would cost far more than a tunnel, but you would be able to go by rail or by car on a bridge, whereas a tunnel would provide a rail link only. Why is this idea being discussed again Is Britain becoming more conscious of the need for links with Europe as a result of joining the EEC (欧共体) Well, perhaps. The main reason, though, is that a tunnel or bridge would reach the twenty square kilometers of London’s disused dockland(船坞地). A link from London to the continent would stimulate trade and re-vitalize(使…重新具有活力)the port, and would make London a main trading center in Europe. With a link over the Channel, you could buy your fish and chips in England and be able to eat them in France while they were still warm! Which of the following statements is TRUE

A. Swimming across the Channel takes less than four hours.
B. The idea of a Channel tunnel or bridge is a very new one.
C. It is considered to be more difficult to swim across the channel than any other means.
D. A tunnel or bridge would only reach as far as the coast.

Computer Needs Emotion The next big breakthrough in artificial intelligence could come from giving machines not just more logical capacity, but emotional capacity as well. Feeling aren’t usually associated with inanimate(无生命的) machines, but Posalind Picard, a professor of computer technology at MIT, believes emotion may be just the thing computes need to work effectively. Computers need artificial emotion both to understand their human users better and to achieve self-analysis and self-improvement, says Picard. "If we want computers to be genuinely intelligent, to adapt to us, and to interact naturally with us, then they will need the ability to recognize and express emotions, to have emotions, and to have what has come to be called emotional intelligence," Picard says. One way that emotions can help computers, she suggests, is by helping keep them from crashing. Today’s computers produce error messages, but they do not have a "gut feeling" of knowing when something is wrong or doesn’t make sense. A healthy fear of death could motivate a computer to stop trouble as soon as it stars. On the other hand, self-preservation would need to be subordinate to service to humans. It was fear of its own death that promoted RAL, the fictional computer in the film 2002: A Space Odyssey, to extermine (消灭) most of its human associates. Similarly, computers that could "read" their users would accumulate a store of highly personal information about us—not just what we said and did, but what we likely thought and felt. "Emotion not only contribute to a richer quality of interaction, but they directly impact a person’s ability to interact in an intelligent way," Picard says. "Emotional skills, especially the ability to recognize and express emotions, are essential for natural communication with humans.\ The phrase "gut feeling" (Par
