内部资料，注意保存 April 8st, 2008 In the United States there was an unusual tale telling of the daughter of a mechanic（技工）. One day while walking along the bank of a lake, the girl 1 to see 20 eggs laid by a wild goose. After some time the girl 2 the mother would not return to her eggs and she 3 to take them home. There she carefully 4 the eggs in the heat of a lamp. Several days 5 the eggs broke and the baby geese came into the 6 . Geese are known to take the first living thing they see as their mother. 7 , to these young geese, the girl was their mother. As they 8 , the girl was able to 9 her birds to run across the grass, but she could not teach them to 10 . The girl became increasingly worried about this, both when 11 and in her dreams. Later, she had an 12 : She would pilot a plane to guide them in 13 . She asked her father for a plane and he assembled（组装）a small aircraft for her. Caring about 14 safety, the father decided to pilot the plane himself. However, the birds did not 15 or follow him, and 16 slept in the grass. One day, the girl 17 into the plane, started it and soon left the 18 . Seeing their mother take to the air, the birds 19 flapped（拍打） their wings and 20 . She flew the plane freely in the sky, her young birds following.

This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise-and as a result, we are ageing unnecessarily soon. Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could be slowed down. With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations. Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and deter-mine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties (功能). Contraction of front and side parts---as cells die off---was observed in some subjects in their thirties, but it was still not evident in some sixty-and-seventy-year-olds. Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age-using the head. The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant. Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. The best way to maintain good blood circulation is through using the brain,” he says. Think hard and engage in conversation. Don’t rely on pocket calculators. 21.
