单选题More than 6,000 children were expelled (开除) from US school last year for bringing guns and bombs to school, the US Department of Education said on May 8. The department gave a report to the expulsions (开除) as saying handguns accounted for 58% of the 6,093 expulsions in 1996—1997, against 7% for rifles (步枪) or shotguns and 35% for other types of firearms. "The report is a clear sign that our nation's public schools are cracking down (严惩) on students who bring guns to school," Education Secretary Richard Riley said in a statement. In March 1997, an 11-year old boy and a 13-year old boy using handguns and rifles shot dead four children and a teacher at a school in Arkansas. In October, two were killed and seven wounded in a shooting at a Mississippi school. Two months later, a 14-year old boy killed three high school students and wounded five in Kentucky. Most of the expulsions, 56%, were from high school, 34% were from junior high schools and 9% were from elementary schools, the report said.

单选题American society is not nap (午睡) friendly. In fact, says David Dinges, a sleep specialist at the University of Pennsylvania School of Medicine. ""There"s even a prohibition against admitting we need sleep. " Nobody wants to be caught napping or found asleep at work. To quote a proverb: "Some sleep five hours, nature requires seven, laziness nine and wickedness eleven. " Wrong. The way not to fall asleep at work is to take naps when you need them. "We have to totally change our attitude toward napping," says Dr. William Dement of Stanford University, the godfather of sleep research. Last year a national commission led by Dement identified an "American sleep debt" which one member said was as important as the national debt. The commission was concerned about the dangers of sleepiness, people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, president Clinton is trying to take a half hour snooze (打瞌睡) every afternoon. About 60 percent of American adults nap when given the opportunity. We seem to have "a midafternoon quiet phase" also called "a secondary sleep gate. " Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap. We Superstars of Snooze don"t nap to replace lost shut eye or to prepare for a night shift. Rather, we "snack" on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, cars, planes and on boats; on floors and beds; and in libraries, offices and museums.

单选题Most graduate programs in American universities produce a product for which there is no market(candidates for teaching positions that do not exist)and develop skills for which there is diminishing demand(research in subfields within subfields and publication in journals read by no one other than a few like-minded colleagues), all at a rapidly rising cost. Widespread hiring freezes and layoffs have brought these problems into sharp relief now. But our graduate system has been in crisis for decades, and the seeds of this crisis go as far back as the formation of modern universities. Kant, in his 1798 work "The Conflict of the Faculties," wrote that universities should "handle the entire content of learning by mass production, so to speak, by a division of labor, so that for every branch of the sciences there would be a public teacher or professor appointed as its trustee. " Unfortunately this mass-production university model has led to separation where there ought to be collaboration and to ever-increasing specialization. In my own department, for example, we have 10 faculty members, working in eight subfields, with little overlap. And as departments fragment, research and publication become more and more about less and less . The emphasis on narrow scholarship also encourages an educational system that has become a process of cloning. Faculty members cultivate those students whose futures they envision as identical to their own pasts, even though their tenures will stand in the way of these students having futures as full professors. The dirty secret of higher education is that without underpaid graduate students to help in laboratories and with teaching, universities couldn't conduct research or even instruct their growing undergraduate populations. That's one of the main reasons we still encourage people to enroll in doctoral programs. It is simply cheaper to provide graduate students with modest stipends and teaching assistants with as little as $ 5, 000 a course—with no benefits—than it is to hire full-time professors. The other obstacle to change is that colleges and universities are self-regulating or, in academic terms, governed by peer review. While trustees and administrations theoretically have some oversight responsibility, in practice, departments operate independently. To complicate matters further, once a faculty member has been granted tenure he is functionally autonomous. Many academics who cry out for the regulation of financial markets vehemently oppose it in their own departments.

单选题The component of the healthy personality that is the first to develop is the sense of trust. As with other personality components, the sense of trust is not something that develops independent of other manifestations of growth. It is not that infants learn how to use their bodies for purposeful movement, learn to recognize people and objects around them, and also develop a sense of trust. Rather, the concept "sense of trust" is a shortcut expression intended to convey the characteristic flavor of all the child's satisfying experiences at this early age. Studies of mentally ill individuals and observations of infants who have been grossly deprived of affection suggest that trust is an early-formed and important element in the healthy personality. Psychiatrists find again and again that the most serious illnesses occur in patients who have been sorely neglected or abused or otherwise deprived of love in infancy. Observations of infants brought up in emotionally unfavorable institutions or moved to hospitals with inadequate facilities for psychological care support these findings. A recent report says that "Infants under 5 months of age who have been in an institution for some time present a well-defined picture. The outstanding features are listlessness, relative immobility, quietness, poor sleep, an appearance of unhappiness, etc. " Another investigation of children separated from their mothers at 6 to 12 months and not provided with an adequate substitute comes to much the same conclusion. Most significant for our present point, these reactions are most likely to occur in children who, up to the time of separation at 6 to 9 months of age, had a happy relation with their mothers, while those whose relations were unhappy are relatively unaffected. It is at about this age that the struggle between trusting and mistrusting the world comes to a climax, for it is then that children first perceive clearly that they and their environment are things apart. That at this point formerly happy infants should react do badly to separation suggests, indeed, that they had a faith that now has been shattered. In most primitive societies and in some sections of our own society, the attention accorded infants is more in line with natural processes. Throughout infancy the baby is surrounded by people who are ready to feed it, fondle it, and otherwise comfort it at a moment's notice. Moreover, these ministrations are given spontaneously and wholeheartedly, and without that element of nervous concern that may characterize the efforts of young mothers made self-conscious and insecure by our scientific age. We must not exaggerate, however. Most infants in our society too find smiles and comfort. As their own bodies come to be more dependable, there is added to the pleasures of increasing sensory response and motor control the pleasure of the mothers' encouragement. Then, too, psychologists tell us that mothers create a sense of trust in their children not by the particular techniques they employ but by the sensitiveness with which they respond to the children's needs and by their overall attitude.
