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 a colleague (同事) 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 (精确的) measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine 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 facilities. 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 workers, bus drivers and shop assistants. 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. The team of doctors wanted to find out______. A．how to make people live longer B．the size of certain people's brains C．which people are most intelligent D．why certain people age sooner than others

You can make your planning more effective by appreciating the direction in which professional careers are shifting within that larger picture.【66】But more than half the students who receive PhDs in science and engineering obtain work outside academe—a proportion that has increased steadily for 2 decades. And full-time academic positions in general are more difficult to find than they were during the 1960s and 1970s, when the research enterprise was expanding more rapidly. 【67】The end of the Cold War has removed some incentive for the federal government to fund defense-oriented basic research. Increased national and global competition has forced many industries to reduce expenses and staff. That means that there are fewer research and development positions in universities, industries, and government laboratories than there are qualified scientists and engineers looking for them. 【68】For example, there are strong public pressures for universities to shift their emphasis toward teaching and toward undergraduate education; the number of positions for permanent faculty has decreased; professors are no longer required to retire at a particular age; and more part-time and temporary faculty are being employed.【69】In engineering, careers are being transformed by several intersecting trends.【70】Companies value multilingual workers with a breadth of competencies—managerial as well as technical—and the ability to access and apply new scientific and technologic knowledge. The more flexible and mobile you can be, the more opportunities you will have and the greater will be your control over the shape of your career. A. Powerful changes have swept through the universities. B. All those trends 'affect the universities' ability to hire scientists and engineers. C. For example, increasing numbers of physicists, mathematicians, and engineers find their skills valued in the financial arena. D. International companies now draw employees from many nations, seeking out valued experts from a global pool of labor to work project by project. E. For example, for many students, a PhD will mean a career as an academic researcher. F. As our society changes, so too do the opportunities for careers in science and engineering. (66)

I have to believe that a great teacher is a great artist and that three are as few as there are any other great artists. It might even be the greatest of the arts since the medium is the human mind and spirit. My three teachers had these things in common: They all loved what they were doing; they did not tell, but stimulated a burning desire to know. Under their influence, the horizons sprang wide and fear went away and the unknown became knowable. I shall speak only of my first teacher because in addition to the other things, she brought discovery. She aroused us to shouting, book-waving discussions. She had the noisiest class in school and she did not even seem to know it. We could never stick to the subject. Our speculation (思绪) ranged the world. She breathed curiosity into us so that we brought in facts or truths shielded in our hands like captured fireflies (萤火虫). She was fired, and perhaps rightly so, for failing to teach fundamentals. Such things must be learned. But she left a passion in us for the pure knowable world and she inflamed me with a curiosity which has never left. I have had many teachers who told me soon-forgotten facts but only three who created in me a new attitude a new hunger. What deathless power lies in the hands of such a person？ 21.
