单选题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./

单选题Cars have traditionally been wasteful beasts. Every time a drop of gas explodes inside a cylinder(气缸), the energy gets passed along from the piston(活塞) to the crankshaft(曲轴), flywheel(飞轮), gearbox, drivetrain, and axles(轮轴). By the time the wheels actually turn, four fifths of the original energy has disappeared. The electric car goes a long way toward reducing wasted energy by replacing the internal-combustion engine with batteries. Even so, electric cars destroy about 60 percent of the energy because mechanical parts are still used to deliver energy from the bakeries to the wheels. Lately, though, engineers have come up with a far more efficient way to accomplish the same task: by using magnets in the wheels. Why do electric cars still waste much of the energy?A. Because they have replaced the internal-combustion engine with bakeries.B. Because they still use mechanical paas to transfer energy to the wheels.C. Because they use magnets in the wheels which add weight to the car.D. Because batteries are not powerful enough to drive the cars.

单选题Eye Movement and Several Faults in Reading Suppose you do this experiment with a friend. Get hold of a book with a large page size and lines that run right across the page. Get your friend to hold the book up and to read it with the top of the book just below his eye level. This means that you can watch the movement of his eyes as he reads the page. If you do this, you will see that your friend's eyes do not make a continuous forward sweep. Instead, they progress by little "jumps" moving, then stopping, as they progress along the line. This kind of jumping movement is called a saccadic movement(跳跃). There has to he this starting and stopping movement because the eye can see only when it is still motionless. Every time the eye pauses it sees a phrase or even a sentence then jumps to the next part of the line and so on. There is another interesting fact about eye movement. If you record the eye movements of someone who is reading, you will notice that, from time to time, the reader goes back and looks again at something he has read before; in other words, he regresses(回视) an earlier part of the text, probably because he realizes he does not understand the passage properly. Then he comes back to where he left off and continues reading. At one time, it was though that regression was a fault, but it is in fact a very necessary activity in efficient reading. There are several different kinds of faults in reading, which are usually more exaggerated with foreign language learners. The most common one is that most people read everything at the same slow speed, and do not seem to realize that they can read faster or slower as required. Other people say the words to themselves, or move their lips-these habits slow the reader down to something near speaking speed, which is of course much slower than reading speed. Another habit that can slow you down is following the line with your finger, or with a pen.
