Many people believe that boys and girls should be educated in separate classes because their brains are to learn in different ways. For the past decade parents and teachers have become worried increasingly about boys, who are now routinely outperformed by girls at every level and who show growing levels of self-dissatisfaction and lack of motivation. Dr. Sax, founder of the National Association for Single Sex Public Education in the United States, argues that this gender gap is the result of innately different learning styles of boys and girls, and that most classrooms play to the strength of girls. Boys, for example, do not hear as well as girls. So,a female teacher with a soft voice may believe that a boy who is not paying attention is playing up, when actually he cannot hear her properly. Her reaction may be to discipline him. But Dr. Sax says that she would get better results by speaking louder and moving purposefully around the classroom. Boys'eyes also respond better to movement and direction, while girls'eyes are more affected by color and texture. Asked to draw, five-year- old girls produce flowers, pets and people. Boys will draw a car crash, but may be reproached by teachers for producing something that is“not nice” 2/5 37. What have parents and teachers become more concerned about in the past ten years? A Boys tend not drop out of school as early as girls. B Boys are unable to compete with girls in school. C Boys tend not to be so self-disciplined as girls. D Boys and girls are educated in different classes.

Rene Descartes’ explanation of pain has long been acknowledged in medicine. He proposed that pain is a purely physical phenomenon — that tissue injury makes specific nerves send a signal to the brain, causing the mind to notice pain. The phenomenon, he said, is like pulling on a rope to ring a bell in the brain. It is hard to overstate how deeply fixed this account has become. In medicine, doctors see pain in Descartes’ terms as a physical process, a sign of tissue injury. The limitations of this explanation, however, have been apparent for some time, since people with obvious injuries sometimes report feeling no pain at all. Later, researchers proposed that Descartes’ model be replaced with what they called the gate control theory of pain. They argued that before pain signals reach the brain, they must first go through a gating mechanism in the spinal cord 脊髓. In some cases, this imaginary gate could simply stop pain signals from getting to the brain. Their most amazing suggestion was that what controlled the gate were not just signals from sensory nerves but also emotions and other “output” from the brain. They were saying that pulling on the rope may not necessarily make the bell ring. The bell itself the mind could stop it. This theory led to a great deal of research into how such factors as mood, gender, and beliefs influence the experience of pain. In a British study, for example, researchers measured pain threshold and tolerance levels in 53 ballet dancers and 53 university students by using a common measurement: after putting your hand in body-temperature water for two minutes to establish a baseline condition, you put your hand in a bowl of ice water and start a clock running. You mark the time when it begins to hurt: that is your pain threshold. Then you mark the time when it hurts too much to keep your hand in the water: that is your pain tolerance. The test is always stopped at 120 seconds, to prevent injury. The results were striking. On average female students reported pain at 16 seconds and pulled their hands out of the ice water at 37 seconds. Female dancers were almost three times as long on both counts. Men in both groups had a higher threshold and tolerance for pain, but the difference between male dancers and male non-dancers was nearly as large. What explains that difference? Probably it has something to do with the psychology of ballet dancers --- a group known for self-discipline, physical fitness, and competitiveness, as well as by a high rate of chronic 慢性 injury. Their driven personalities and competitive culture evidently accustom them to pain. Other studies along these lines have shown that outgoing people have greater pain tolerance and that, with training, one can reduce one’s sensitivity to pain. There is also striking evidence that very simple kinds of mental suggestion can have powerful effects on pain. In one study of 500 patients undergoing dental procedures, those who were given a placebo injection 安慰剂 and promised that it would relieve their pain had the least discomfort --- not only less than the patients who got a placebo and were told nothing but also less than the patients who got actual drug without any promise that it would work. Today it is abundantly evident that the brain is actively involved in the experience of pain and is no more bells on a string. Today every medical textbook teaches the gate control theory as fact. There’s a problem with it, though. It explains people who have injuries but feel no pain, but it doesn’t explain the reverse, which is far more common --- the millions of people who experience chronic pain, such as back pain, with no signs of injury whatsoever. So where does the pain come from? The rope and clapper are gone, but the bell is still ringing.71. The primary purpose of the passage is to ________. A. describe a modern theory about pain B. support a traditional view on pain with new data C. promote a particular attitude towards pain D. suggest a creative treatment for pain72.

A. offered an extremely new and original explanation B. was just opposite to people’s everyday experiences C. was grounded in a ridiculous logic D. was so sensible that it should have been proposed centuries before74. The author refers to “chronic back pain” as an example of something that is _______. A. costly, because it troubles millions of people B. puzzling, because it sometimes has no obvious cause C. disappointing, because it does not improve with treatment D. worrying, because it lies beyond the reach of medicine75. From the passage we know that ________. A. all the theories about pain are not correct B. some data from the researches on pain is wrong C. there has been no perfect theory about pain so far D. one’s mood can’t affect the pain one feels
