单选题The war was the most peaceful period of my life. The window of my bedroom faced southeast. My mother had curtained it, but that had small effect. I always woke up with the first light and, with all the responsibilities of the previous day melted, felt myself rather like the sun, ready to shine and feel joy. Life never seemed so simple and dear and full of possibilities as then. I stuck my feet out under the sheets—I called them Mrs. Left and Mrs. Right—and invented dramatic situations for them in which they discussed the problems of the day. At least Mrs. Right did; she easily showed her feelings, but I didn't have the same control of Mrs. Left, so she mostly contented herself with nodding agreement. They discussed what Mother and I should do during the day, what Santa Claus should give a fellow for Christmas, and what steps should be taken to brighten the home. There was that little matter of the baby, for instance. Mother and I could never agree about that. Ours was the only house in the neighborhood without a new baby, and Mother said we couldn't afford one till Father came back from the war because it cost seventeen and six. That showed how foolish she was. The Geneys up the road had a baby, and everyone knew they couldn't afford seventeen and six. It was probably a cheap baby, and Mother wanted something really good, but I felt she was too hard to please. The Geneys' baby would have done us fine. Having settled my plans for the day, I got up, put a chair under my window, and lifted the frame high enough to stick out my head. The window overlooked the front gardens of the homes behind ours, and beyond these it looked over a deep valley to the tall, red-brick house up the opposite hillside, which were all still shadow, while those on our side of the valley were all lit up, though with long storage shadows that made them seam unfamiliar, stiff and painted. After that I went into Mother's room and climbed into the big bed. She woke and I began to tell her of my schemes. By this time, though I never seem to have noticed it, I was freezing in my nightshirt, but I warmed up as I tallied until the last frost melted. I fell asleep beside her and woke again only when I heard her below in the kitchen, making breakfast.

单选题To sleep. Perchance to file? Findings published online this week by the Proceedings of the National Academy of Sciences further support the theory that the brain organizes and stows memories formed during the day while the rest of the body is catching zzz's. Gyorgy Buzsaki of Rutgers University and his colleagues analyzed the brain waves of sleeping rats and mice. Specifically, they examined the electrical activity emanating from the somatosensory neocortex (an area that processes sensory information) and the hippocampus, which is a center for learning and memory. The scientists found that oscillation in brain waves from the two regions appear to be intertwined. So-called sleep spindles (bursts of activity from the neocortex) were followed tens of milliseconds later by beats in the hippocampus known as ripples. The team posits that this interplay between the two brain regions is a key step in memory consolidation. A second study, also published online this week by the Proceedings of the National Academy of Sciences, links age-associated memory decline to high glucose levels. Previous research had shown that individuals with diabetes suffer from increased memory problems. In the new work, Antonio Convit of New York University School of Medicine and his collaborators studied 30 people whose average age was 69 to investigate whether sugar levels, which tend to increase with age, affect memory in healthy people as well. The scientists administered recall tests, brain scans and glucose tolerance tests, which measure how quickly sugar is absorbed from the blood by the body's tissues. Subjects with the poorest memory recollection, the team discovered, also displayed the poorest glucose tolerance. In addition, their brain scans showed more hippocampus shrinkage than those of subjects better able to absorb blood sugar. "Our study suggests that this impairment may contribute to the memory deficits that occur as people age." Convit says. "And it raises the intriguing possibility that improving glucose tolerance could reverse some age-associated problems in cognition." Exercise End weight control can help keep glucose levels in check, so there may be one more reason to go to the gym.

单选题Concern with money, and then more money, in order to buy the conveniences and luxuries of modern life, has brought great changes to the lives of most Frenchmen. More people are working than ever before in France. In the cities, the traditional leisurely midday meal is disappointing. Offices, shops, and factories are discovering the great efficiency of a short lunch hour in company lunchrooms. In almost all lines of work, emphasis now falls on ever-increasing output. Thus he "typical" Frenchman produces more, earns more, and buys more consumer goods than his counterpart of the last generation. He gains in creating comforts and ease of life. What he loses to some extent is his sense of persona, uniqueness, or individuality. Some say that France has been Americanized. This is because the U. S. is a world symbol of the technological society and its consumer products. The so-called Americanization of France has its critics. They fear that "assembly-line life" will lead to the disappearance of the pleasures of the more graceful and leisurely (but less productive) old French style. What will happen, they ask, to taste, elegance, and the cultivation of the good things in life—joy in the smell of a freshly picked apple, a stroll by the river, or just happy hours of conversation in a local care? Since the late 1950s, life in France has indeed taken on qualities of rush, tension, and the pursuit of material gain. Some of the strongest critics of the new way of life are the young, especially university students. They are concerned with the future, and they fear that France is threatened by the triumph of this competitive, goods-oriented culture. Occasionally, they have reacted against the trend with considerable violence. In spite of the critics, however, countless Frenchmen are committed to keeping France in the forefront of the modern economic world. They find that the present life brings more rewards, convenience, and pleasures than that of the past. They believe that a modern, industrial France is more preferable to the old.
