However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk.

He was about to give up and quit before this point. Years later the young woman became critically ill. The local doctors were baffled. They finally sent her to the big city, where specialists can be called in to study her rare disease. Dr. Howard Kelly, now famous was called in for the consultation. When he heard the name of the town she came from, a strange light filled his eyes. Immediately, he rose and went down through the hospital hall into her room. Dressed in his doctor's gown he went in to see her. He recognized her at once. He went back to the consultation room and determined to do his best to save her life. From that day on, he gave special attention to her case. After a long struggle, the battle was won. Dr. Kelly requested the business office to pass the final bill to him for approval.

Andrew Whiten of St. Andrews University in Fife, Scotland, and his colleagues studied three groups of captive chimpanzees and the ways in which they assumed different techniques for obtaining food. The first group contained a high-ranking female that had been taught to retrieve food from an apparatus by using a stick to push a blockage away, thus freeing the food item. The second group also contained a female expert, but one that had been instructed to lift the blockage with the stick in order to release the treat. The third group was a control group and did not have a local expert. When the experts were reunited with their respective group, the other chimps watched their activities at the food apparatus intently and learned to apply either the poking or lifting technique themselves. Members of the third group, lacking an expert to guide them, failed to figure out the contraption on their own. For the most part, chimps in the first group initially stuck to poking and those in the second group stuck to lifting. But then, unexpectedly, some chimps discovered and began using the other strategy. When the food apparatus was reintroduced two months later, however, the chimps reverted to their group's normal way of doing things. In the case of those animals in the lifting group, this meant discarding a technique (poking) that is actually more natural for chimpanzees than lifting is. "We have shown a non-human species conforming to a group norm, despite possession of an alternative technique that represents the norm of another group," the team writes in a report published online by the journal Nature. "Conformity fits the assumption of an intrinsic motivation to copy others, guided by social bonds rather than material rewards such as food." The phrase "fit in" (Line l, Para. I) most likely means ______. A．suit B．adopt C．adjust D．conform

The intelligent person, young or old, meeting a new situation or problem, opens himself up to it. He tries to take in with mind and senses everything he can about it. He thinks about it, instead of about himself or what it might cause to happen to him. He grapples (努力克服) with it boldly, imaginatively, resourcefully (机智地), and if not confidently, at least hopefully: if he fails to master it, he looks without fear or shame at his mistakes and learns what he can from them. This is intelligence. Clearly its roots lie in a certain feeling about life, and one’s self with respect to life. Just as clearly, unintelligence is not what most psychologists seem to suppose, the same thing as intelligence, only less of it. It is an entirely different style. of behavior, arising out of entirely different set of attitudes. Years of watching and comparing bright children with the not-bright, or less bright, have shown that they are very different kinds of people. The bright child is curious about life and reality, eager to get in touch with it, embrace (捉住机会) it, unite himself with it. There is no wall; no barrier, between himself and life. On the other hand, the dull child is far less curious, far less interested in what goes on and what is real, more inclined (倾向于) to live in a world of fantasy. The bright child likes to experiment, to try things out. He lives by the maxim (格言) that there is more than one way to skin a cat. If he can’t do something one way, he’ll try another. The dull child is usually afraid to try at all. It takes a great deal of urging to get him to try even once; if that try fails, he is through. Nobody starts off stupi D.Hardly an adult in a thousand, or ten thousand, could in any three years of his life learn as much, grow as much in his understanding of the world around him, as every infant (婴儿) learns and grows in his first three years. But what happens, as we grow older, to this extraordinary capacity for learning and intellectual growth？ What happens is that it is destroyed, and more than by any other one thing, it is destroyed by the process that we misname education – a process that goes on in most homes and schools. 11.

B.All work and no play makes Johnny a dull boy. C.Make new friends and keep the old; one is silver and the other is gold. D.Make hay while the sun shines. 15. “It is an entirely different style. of behavior, arising out of an entirely different set of attitudes.” “It” in this sentence refers to （） .
