For an increasing number of students at American universities, Old is suddenly in. The reason is obvious: the graying of America means jobs. Coupled with the aging of the baby-boom(生育高峰) generation, a longer life span means that the nation"s elderly population is bound to expand significantly over the next 40 years. By 2040, 25 percent of all Americans will be older than 65, up from 14 percent in 1995. The change poses profound questions for government and society, of course. But it also creates career opportunities in medicine and health professions, and in law and business as well. "In addition to the doctors, we"re going to need more sociologists, biologists, urban planners and specialized lawyers", says Professor Edward Schneider of the University of Southern California"s (USC) School of Gerontology(老年学). Lawyers can specialize in "elder law", which covers everything from trusts and estates to nursing-home abuse and age discrimination(岐视). Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees in human history. "Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree, will have a license to print money", one professor says. Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was "really bored with bacteria". So she took a class in gerontology and discovered that she liked it. She says, "I did volunteer work in retirement homes and it was very satisfying".

After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report; The damage and death toll could have been much worse. More than 60 people died in this earthquake. By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25,000 victims. Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a.m. on a holiday, when traffic was light on the city"s highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city"s buildings and highways, making them more resistant to quakes. Despite the good news, civil engineers aren"t resting on their successes. Pinned to their drawing boards are blueprints for improved quake-resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place. In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports, called smart buildings, the structures respond like living organisms to an earthquake"s vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction. The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.

How much sleep does a person need?【B1】the physiological bases of the need for sleep remain conjectural(猜想), rendering conclusive answers to this question impossible, much evidence has been gathered on how much sleep people do in fact obtain. Perhaps the most important conclusion to be【B2】from this evidence is【B3】there is great variability among individuals in total sleep time. For adults,【B4】between six and nine hours of sleep as a nightly average is not unusual, and 7.5 hours probably best expresses the norm. Such norms, of course, forms inevitably vary with the criteria of sleep employed. The most【B5】and reliable figures on sleep time, including those cited here, come from studies in sleep laboratories, where EEO criteria are employed. 【B6】consistently has been associated with the varying amount, quality, and pattern of electrophysiologically defined sleep. The newborn infant may spend an average of about 16 hours of each 24-hour period in sleep,【B7】the sleep time drops sharply; by two years of age, it may【B8】from nine to 12 hours. Decreases to approximately six hours have been observed among the elderly. 【B9】will be discussed from below, EEO sleep studies have indicated that sleep can be considered to consist of several different stages. Developmental changes in the relative proportion of sleep time【B10】in these sleep stages are as striking as age-related changes in total sleep time.

Ever won the lottery? No? But did that stop you buying another lottery ticket? If the answer is another " no, " you might call yourself an optimist. According to researchers at University College London, human beings are sanguine creatures. It is all in the brain, they say. A study suggests that human brain is very efficient at processing good news: about 80% of people have a tendency to see the glass as half-full, not half-empty, even if they don"t consider themselves to be optimists. The good news is that this brings a health benefit, having a positive outlook on life reduces anxiety. A study of nearly 100, 000 women showed a lower risk of death from heart disease among optimists. But there are problems in always having an optimistic attitude. The authors of the study point out that the 2008 financial crisis may have been caused by analysts overestimating their assets" performance even in the face of clear evidence to the contrary. There are personal health risks too. Dr Tali Sharot, lead researcher, said: "Smoking Kills" messages don"t work since people think their chances of cancer are low. There"s a very fundamental tendency in the brain. " But, as they say, every cloud has a silver lining. Even if seeing the world through rose-colored glasses poses a risk to our health, it"s not something that is likely to cause us to lose sleep. Let"s just keep our chins up and keep smiling!

During the summer session there will be a revised schedule of services for the university community. Specific changes for intercampus bus services, summer hours for the cafeteria, the infirmary(校医院) and recreational and athletic facilities will be posted on the bulletin board outside of the cafeteria. Weekly movie and concert schedules which are in the process of being arranged will be posted each Wednesday outside of the cafeteria. Intercampus buses will leave the main hall every hour on the half hour and make all of the regular stops on their route around campus. The cafeteria will serve breakfast, lunch, and early dinner from 7 a.m. to 7 p.m. during the week and from noon to 7 p.m. on weekends. The library will maintain regular hours during the week, but shorter hours on Saturdays and Sundays. The weekend hours are from noon to 7 p.m. All students who want to use the library borrowing services and recreational athletic, and entertainment facilities must have a valid summer identification card. This announcement will also appear in the next issue of the student newspaper.

In bringing up children, every parent watches eagerly the child"s acquisition(学会) of each new skill the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child"s own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality(道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practise what they preach(说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents" principles and their morals can be a dangerous disappointment.
