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

Now, health advocates say, an ill-conceived redesign-has taken one of the more successful public-health campaigns—the Food Guide Pyramid—and rendered it confusing to the point of uselessness. Some of these critics worry that America's Department of Agriculture caved to pressure from parts of the food industry anxious to protect theft products. The Food Guide Pyramid was a graphic which emphasizes that a healthy diet is built on a base of gains, vegetables and fruits, followed by ever-decreasing amounts of dairy products, meat, sweets and oils. The agriculture department launched the pyramid in 1992 to replace its previous program, which was centered on the idea of four basic food groups. The "Basic Four" campaign showed a plate divided into quarters, and seemed to imply that meat and dairy products should make up haft of a healthy diet, with grains, fruits and vegetables making up the other half. It was replaced only over the strenuous objections of the meat and dairy industries. The old pyramid was undoubtedly imperfect. It failed to distinguish between a doughnut and a whole-grain roll, or a hamburger and a skinless chicken breast, and it did not make clear exactly how much of each foodstuff to eat. It did, however, manage to convey the basic idea of proper proportions in an easily understandable way. The new pyramid, called "My Pyramid", abandons the effort to provide this information. Instead, it has been simplified to a mere logo. The food groups are replaced with unlabelled, multi-colored vertical stripes which, in some versions, rise out of a cartoon jumble of foods that look like the aftermath of a riot at a grocery store. Anyone who wants to see how this translates into a healthy diet is invited to go to a website, put in their age, sex and activity level, and get a custom-designed pyramid, complete with healthy food choices and suggested portion sizes. This is free for those who are motivated, but might prove too much effort for those who most need such information. Admittedly, the designers of the new pyramid had a tough job to do. They were supposed to condense the advice in the 84-page United States' Dietary Guidelines into a simple, meaningful graphic suitable for printing on the back of a cereal box. And they had to do this in the face of pressure from dozens of special interest groups—from the country's Potato Board, which thought potatoes would look nice in the picture, to the Almond Board of California, which felt the same way about almonds. Even the National Watermelon Promotion Board and the California Avocado Commission were eager to see their products recognized. Nevertheless, many health advocates believe the new graphic is a missed opportunity. Although officials insist industry pressure had nothing to do with the eventual design, some critics suspect that political influence was at work. On the other hand, it is not clear how much good even the best graphic could do. Surveys found that 80% of Americans recognized the old Food Guide Pyramid—a big success in the world of public-health campaigns. Yet only 16% followed its advice. Trying to get Americans to eat a healthy diet is a frustrating business can be easily proved by the fact that A．public-health campaigns cannot compete with tempting flavors. B．snack-food and fast-food industries are flourishing in the US. C．most food in America are profoundly rich in fat and sugar. D．fat people account for a large proportion of American population.

When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration (迁移) is probably the migration of fish, which is called "salmon". This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea. Recently, scientists have studied the migration of a kind of lobster (龙虾). Every year, when the season of bad weather arrives, the lobsters get into a long line and start to walk across, the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don't. Maybe living things just like to travel. Most animals move from one place to another at a certain time to ______. A．give birth B．enjoy warmer weather C．find food more easily D．find beautiful places

I've twice been to the wars, and as I survey the battlefield, something different is happening. It's the one-upmanship among parents. We see our kids' college rating as medals proving how well or how poorly we've raised them. But we can't acknowledge that our obsession is more about us than them. So we've contrived various justifications that turn out to be half-truths, prejudices or myths. It actually doesn't matter much whether Aaron and Nicole go to Stanford. Admissions anxiety afflicts only a minority of parents. It's true that getting into college has generally become tougher because the number of high-school graduates has grown. From 1994 to 2006, the increase is 28 percent. Still, 64 percent of freshmen attend schools where acceptance rates exceed 70 percent, and the application surge at elite schools dwarfs population growth. Take Yale. In 1994, it accepted 18.9 percent of 12,991 applicants; this year it admitted only 8.6 percent of 21,000. We have a full-blown prestige panic; we worry that there won't be enough medals to go around. Fearful parents prod their children to apply to more schools than ever. "The epicenters (of parental anxiety) used to be on the coasts, Boston, New York, Washington, Los Angeles", says Tom Parker, Amherst's admissions dean. "But it's radiated throughout the country". Underlying the hysteria is the belief that scarce elite degrees must be highly valuable. Their graduates must enjoy more success because they get a better education and develop better contacts. All that's plausible and mostly wrong. "We haven't found any convincing evidence that selectivity or prestige matters", says Ernest T. Pascarella of the University of Iowa, co author of "How College Affects Students", an 827-page evaluation of hundreds of studies of the college experience. Selective schools don't systematically employ better instructional approaches than less-selective schools, according to a study by Pascarella and George Kuh of Indiana University. Some do; some don't. On two measures professors' feedback and the number of essay exams selective schools do slightly worse. In the author's eyes, parents pushing their kids to an elite degree are ______. A．aggressive B．misguided C．reasonable D．failing

Even though very small (4) of each vitamin are enough for the (5) of the body, the worry people have about vitamins has some basis. And this has to do (6) their diet---the food they take in. A person eating a good (7) of foods get all the vitamins now (8) to be needed. The problem is that there are many people (9) don’t choose foods wisely. So the answer (10) this question is: No (11) vitamins are needed, (12) you eat proper foods. In fact, many of the vitamins cannot be (13) in the body, so when extra vitamins are taken in, the body simply gets rid of them. It is even (14) to put too much of certain vitamins into the body. This has been found to be true (15) vitamin A and D, when large amounts are taken (16). What foods supply what vitamins？ Here is a quick (17) idea. Vitamin A for the (18) of the eyes, skin, teeth, and bones, is found in green vegetables, fruits, eggs, liver and butter. Vitamin B1 which (19) the nervous and digestive (20) and prevents certain diseases, is found in cereals, pork and liver. VitaminB2 is found in milk, eggs, green vegetables and meats.
