Of all the components of a good night's sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just 'mental noise'—the random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind's emotional thermostat, regulating moods while the brain is 'off-line.' And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better. 'It's your dream,' says Rosalind Cartwright, chair of psychology at Chicago's Medical Center, 'If you don't like it, change it.' The link between dreams and emotions shows up among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don't always think about the emotional significance of the day's events—until, it appears, we begin to dream. And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep. At the end of the day, there's probably little reason to pay attention to our dreams at all unless they keep us from sleeping or 'we wake up in panic,' Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people's anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep—or rather dream—on it and you'll feel better in the morning.

In today's world, insurance plays a vital role in the economic and social welfare of the entire population. The wish to guard against dangers to life and property is basic to human nature. By using various kinds of insurance, society has been able to reduce the effects of such hazards. Nowhere is insurance more important than in the management of a business. In many instances, losses in a small firm can mean the difference between growth and failure, vitality and stagnation (停滞).Very few small businesses have even a portion of the financial resources available to larger enterprises. Frequently, they must operate on a very slight margin if they hope to stay in business. And thus, they are particularly sensitive to unexpected losses. Without enough insurance, what happens to such a firm when the owner dies or is suddenly disabled? When a fire breaks out and destroys the firm's building or stock? When an employee is found to have stolen company funds? When a customer is awarded a liability judgment for an accident? Too often, the business isforced to the wall, its future operations drasticallycurbed; sometimes, it is damaged beyond repair, its ability to continue completely crushed. Almost always, a small businessman would find it impossible to handle the full burden of his potential risk. The amount of money he would have to set aside to cover possible losses would leave him nothing, or almost nothing, to run his business with. If loss were to occur which he could repair by using his reserve fund, what assurance would he have that another loss—the same kind or different—might not occur next week, next month? But then he would have no reserve fund and little likelihood of staying in business at all.

China's obesity(肥胖)problem work group recently issued the first ever obesity index for Chinese adults, based on data analyses in the 1990s, according to an article published on 'Popular Medicine' written by Professor Zhou Beifan with the China Academy of Medical Science. Obesity is 51 judged and diagnosed according to the Body Mass Index(BMI)— body weight(kilogram)/square of body height(meter)— 52 by the World Health Organization, but the result was 53 out on the 54 of western people and therefore not 55 to Asians. Under the same calculating method China 56 the result for its own folks, according to 57 one is overweighed when his or her body mass index surpasses or equals to 24, and 58 when the index surpasses(超过)or equals to 28. Besides, a male gets abdominal obese when his waistline reaches or surpasses 85 cm and a female 80 cm. Waistline(腰围)is an important measurement for abdominal obesity, because it 59 one's abdominal(腰部的)adiposity(发胖倾向), which has 60 to do with a 61 of metabolic(新陈代谢的)disorders. The body mass index increases along with the risks of getting stroke and coronary heart diseases. With the index increasing 2, the 62 for coronary heart diseases(冠心病)and stroke increase 15.4 and 6.1 percent 63 , the work group 64 out. 65 the index reaches or surpasses 24, one's more 66 to have risks for high blood pressure, diabetes(糖尿病)and hyperlipidemia(高血脂)at the same time; the possibility exceeds 90 percent when the index 67 or surpasses 28. It should also be noted that the risks 68 when one's index is 69 normal range but the waistline reaches 80 or 85 cm. If the index is 70 normal range and waistline also passes 80 or 85 cm, the risks for diabetes and coronary heart diseases would be extremely high.

There are a great many careers in which the increasing emphasis is on specialization. You find these careers in engineering, in production, in statistical work, and in teaching. But there is an increasing demand for people who are able to take in a great area at a glance, people who perhaps do not know too much about any one field. There is, in other words, a demand for people who are capable of seeing the forest rather than the trees, of making general judgments. We can call these people 'generalists'. And these 'generalists' are particularly needed for positions in administration, where it is their job to see that other people do the work, where they have to plan for other people, to organize other people's work, to begin it and judge it. The specialist understands one field; his concern is with technique and tools. He is a 'trained' man; and his educational background is properly technical or professional. The generalist --- and especially the administrator --- deals with people; his concern is with leadership, with planning, and with direction giving. He is an 'educated' man; and the humanities(人文学)are his strongest foundation. Very rarely is a specialist capable of being an administrator. And very rarely is a good generalist also a good specialist in a particular field. Any organization needs both kinds of people, though different organizations need them in different proportions. It is your task to find out, during your training period, into which of the two kinds of jobs you fit, and to plan your career accordingly. Your first job may turn out to be the right job for you, but this is pure accident. Certainly you should not change jobs constantly or people will become suspicious of your ability to hold any job. At the same time you must not look upon the first job as the final job; it is primarily a training job, an opportunity to understand yourself and your fitness for being an employee.
