Every time a person eats something he makes a nutritional decision. He accepts or rejects the food available to him at home for meals or snacks. Or he selects food for himself at many places in the community, such as supermarkets, drive-ins, restaurants, and food counters in drugstores. These selections make a difference in how an individual looks, how he feels, and how well he can work and play.When a good assortment of food in appropriate amounts is selected and eaten, the consequences are more likely to be a desirable level of health and enough energy to allow one to be as active as one needs and wants to be. When choices are less than desirable, the consequences are likely to be poor health or limited energy or both.Studies of diets of individuals in the United States show that food selection is a highly individual matter, even among young children. Furthermore, far too many individuals of all ages are making poor choices day after day and are either now living with the consequences or will be in the future.Nutritionists and workers in allied professions have been concerned about helping people learn to select and enjoy a wide variety of food combinations that can add up to a good diet.Most people believe that they are well fed—that the choices they make are good ones. After all, they are not really sick, neither are they hungry. However, their nutrition is usually poor in one respect or another. Milk and milk products, such as cheeses, ice cream or milk, buttermilk, and yogurt, are often slighted. Then people may skip many fruits and vegetables, particularly those that are good sources of vitamins A and C.These include dark green leafy vegetables; deep yellow vegetables; and citrus fruits and vegetables, such as cabbage, tomatoes, and green peppers.Every American has the right to choose to be uniformed about nutrition as well as to be informed. If a person believes that she is well fed, attitudes, habits, and information cannot be forced upon her.There are life situations, however, that tend to cause all individual to want to know how to make the best choices. For example, a young couple is starting a family and must prepare food for young children.

Yoga,the ancient practice of postures, breathing and meditation, is gaining a lot of attention from the material world that its serious practitioners are trying to escape.Yoga practitioners are trying to keep themselves away from the material world.And no wonder. Americans who practice yoga are often well-educated, have higher-than -average household income and are willing to spend a bit more on so-called "green" purchases seen as benefiting the environment or society."It's kind of growing out of the crunchy stage of yoga to the Starbucks stage," said Bill Harper, publisher of Yoga Journal. "From the videos and the clothes and the toe socks...people are pursuing this market with a vengeance." A glance through recent issues of his monthly magazine, whose readership has doubled in the past four years to 325,000, illustrates the point. There are four-color ads from the likes of Asics athletic shoes, Eileen fisher apparel and Ford Motor Co. Yoga Journal is now licensing a Russian edition and preparing to expand in other international markets.Americans spend some $2.95 billion a year on yoga classes, equipment, clothing, holidays, videos and more, according to a study commissioned by the magazine, fuelled in part by ageing baby boomers seeking less aggressive ways to stay fit.Roughly 16.5 million people were practising yoga in the United States early last year, in studios, gyms or at home, up 43 percent from 2002, the study found.Established sellers of yoga gear such as Hugger Mugger and Gaiam have been flooded with competition in the market for y

73. 5 percent of major U.S. firms report that they record and review their employees' communications and activities on the joB.The larger the company, the more likely it is to engage in monitoring and surveillance activities, according to a survey. Broken down by business category, survey respondents in the financial services sector lead the packs when it comes to monitoring their employees e-mail and Internet connections.Weber says he sees companies go through a "life cycle" with their Internet experience. When they first get connected, companies see a surge of activity and an immediate drop-off in productivity. After about two or three weeks, Internet use levels off, Weber notes. Weber observes that among his clients, he's seeing a trend where employers are letting the life cycle run its course. In other cases, Weber says his clients are capturing the information, but not really doing anything about it. One thing the experts all agree on is that if you use the Internet and provide access to your employees, you should have a policy in place that defines what you deem to be permissible use by employees. Weber believes that no company wants to be in the rote of Big Brother, but still must protect one of its most valuable assets. Nor are employers looking to micro-manage their employees. Many companies are viewing use of the Internet as similar to the phone, and operating with the philosophy that incidental personal use is okay. "But some clients don't see a need to restrict access," he explains. For certain the issues that surround monitoring employee Internet use aren't going to quiet down anything soon, the experts say. "Maybe the simplest solution is to just allow a certain percentage to go to employee use."1.In monitoring the Internet use of the employees, which of the following take the lead?2.Which of the following may rightly describe the lifecycle of Internet use（ ）3.What can we say about most companies' attitude t

The more time scientists spend designing computers the more they marvel at the human brain. Tasks that baffle（難住）the most advanced supercomputer — recognizing a face, reading a handwritten note 一 are child's play for the 3-pound organ. Most important, unlike any conventional computer, the brain can learn from its mistakes. Researchers have tried for years to program computers to imitate the brain's abilities, but without success. Now a growing number of designers believe they have the answer: if a computer is to function more like a person and less like an over-grown calculator it must be built more like a brain, which distributes information across a vast interconnected web of nerve cells, or neurons.Conventional computers function by following a chainlike sequence of detailed instructions. Although very fast, their processors can perform only one task at a time. This approach works best in solving problems that can be broken down into simpler logical pieces. The processors in a neural-network computer, by contrast, form a network much like the nerve cells in the brain. Since these artificial neurons are interconnected, they can share information and perform tasks at the same time. This two-dimensional approach works best at recognizing patterns.Instead of programming a neural-network computer to make decisions, its maker trains it to recognize patterns in any solution to a problem by repeatedly feeding examples to the machine.Neural networks come in all shapes and sizes. Until now most existed as software simulations（模擬品）because redesigning computer chips took a lot of time and money. By experimenting with different approaches through software rather than hardware, scientists have been able to avoid costly mistakes. 1.It can be inferred from the first paragraph that the most advanced supercomputer （ ）.2.What is NOT true of a conventional computer?3.
