单选题However important we may regard school life to be, there is no denying the fact that children spend more time at home than in the classroom. Therefore, the great influence of parents cannot be ignored or discounted by the teacher. They can become strong allies of the school personnel or they can consciously or unconsciously hinder and frustrate curricular objectives. Administrators have been aware of the need to keep parents informed of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program, manuscript writing and developmental mathematics. Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The informal tea and the many interviews carried on during the year, as well as new ways of reporting pupils" progress, can significantly aid in achieving a harmonious interplay between school and home. To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent sublimate his natural paternal interest into productive channels. He might be persuaded to let Junior participate in discussing the family budget, buying the food, using a yardstick or measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis. If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics, and at the same time, enjoying the work. Too often, however, teachers" conferences with parents are devoted to petty accounts of children"s misdemeanors, complaints about laziness and poor work habits, and suggestion for penalties and rewards at home. What is needed is a more creative approach in which the teacher, as a professional adviser, plants ideas in parents" minds for the best utilization of the many hours that the child spends out of the classroom. In this way, the school and the home join forces in fostering the fullest development of youngsters" capacities.

单选题 Naturally, in a group of animals as diverse as the snakes, and with so many varied enemies, there are numerous defensive reactions and devices. There is, however, one general pattern of hehaviour, in the presence of a suspected enemy the first reaction is to try to escape observation; if this fails, the next resort is flight to some inaccessible retreat, but if this is not possible, or is circumvented, various kinds of intimidatory gestures and warning devices arc brought into play ;in the last resort the snake attacks. This pattern varies with the circumstances; some stages may be omitted or combined unpredictably whilst some notoriously irascible species may dispense with all the preliminaries and attack almost at once, though seldom or never without some provocation. The difficulty is to know what constitutes provocation, a matter that is apt to be debatable in other fields! Amongst the factors that increase aggressiveness are hunger, the mating season and surprise, with the last mentioned the commonest ; when hunting for food or for mates, activity and the aggressive instinct are both at their peak, but it is when it is caught unawares that the normal chain of re- actions tends to become telescoped. Owing to their poor sense of hearing, snakes are very liable to be, quite literally, caught napping and a similar situation arises during their periods of temporary blindness just before sloughing begins. By far the greatest number of snake-bite accidents result from the unwitting disturbance of resting snakes, and this hazard is much increased with species that are well camouflaged and whose natural instinct is to trust to this concealment as their principal defence. As well as differences in aggressiveness between individuals of the same species according to the circumstances and conditions, there are also notable differences between species ,even closely allied species; and the reports of those who have been attacked may understandably be lacking in objectivity. So it is impossible to forecast, even in outline, how any encounter will develop. The Hamadryad, for example,is usually credited with being amongst the most aggressive of snakes ,and there are many accounts of unprovoked attacks ;yet on one occasion fourteen men and seven dogs passed and returned within two yards of a nest and no snake was seen although the fe- male, which guards the nest, could not have been far. away. One very well-known student of snakes once parked his car under some trees near Nairobi and on his return found a small green snake on it. Being preoccupied at the moment he gave it only a cursory glance and, thinking it was a common harmless tree-snake, bundled it unceremoniously into his pocket ;it was, as he later discovered to his horror, a young Green Mamba, but it made no attempt to bite despite the rough treatment it had received. The proportion of the snakes of the world that have some forms of procrypsis( i. e. resemblance to the background)is very high, but the frequency with which the resemblance results in accidents suggests that it is incorrect to regard it as primarily a "protective" device. There is every advantage to a predatory animal in being unobserved until its prey comes within striking distance, but it is distinctly hazardous to allow an enemy to approach closely with the hope ,but no certainty, of remaining undetected. The commonest type of proerypsis is the result of colours that harmonize with hose of the normal background, associated with patterns that disrupt the animal' s outline or produce "counter shading" whereby those parts of the body that will be seen in shadow and appear dark, are lighter in colour whilst highlight areas are dark-coloured.

单选题The concept of man versus machine is at least as old as the industrial revolution, but this phenomenon tends to be most acutely felt during economic downturns and fragile recoveries. And yet, it would be a mistake to think we are right now simply experiencing the painful side of a boom and bust cycle. Certain jobs have gone away for good, outmoded by machines. Since technology has such an insatiable appetite for eating up human jobs, this phenomenon will continue to restructure our economy in ways we can"t immediately foresee. When there is rapid improvement in the price and performance of technology, jobs that were once thought to be immune from automation suddenly become threatened. This argument has attracted a lot of attention, via the success of the book Race Against the Machine, by Erik Brynjolfsson and Andrew McAfee, who both hail from MIT"s Center for Digital Business. This is a powerful argument, and a scary one. And yet, John Hagel, author of The Power of Pull and other books, says Brynjolfsson and McAfee miss the reason why these jobs are so vulnerable to technology in the first place. Hagel says we have designed jobs in the U.S. that tend to be "tightly scripted" and "highly standardized" ones that leave no room for "individual initiative or creativity." In short, these are the types of jobs that machines can perform much better at than human beings. That is how we have put a giant target sign on the backs of American workers, Hagel says. It"s time to reinvent the formula for how work is conducted, since we are still relying on a very 20th century notion of work, Hagel says. In our rapidly changing economy, we more than ever need people in the workplace who can take initiative and exercise their imagination "to respond to unexpected events." That is not something machines are good at. They are designed to perform very predictable activities. As Hagel notes, Brynjolfsson and McAfee indeed touched on this point in their book. We need to reframe race against the machine as race with the machine. In other words, we need to look at the ways in which machines can augment human labor rather than replace it. So then the problem is not really about technology, but rather, "how do we innovate our institutions and our work practices?"

单选题 Sea horses have unusual parents. The female sea horses lay the eggs, but unlike other creatures. It's the males that give birth to the young. Male sea horses have a fold of skin on their bellies that forms a pocket, called a brood pouch. During the breeding season, the sea horse's pouch swells to receive eggs. A female sea horse lays Up to 200 eggs at a time in the pouch. Then she swims off, leaving her male partner to care for the developing eggs and give birth to young sea horses. The female will return every day to check on her mate and the eggs, but she doesn't stay long, nor does she take part in the birth. It takes from five to six weeks for the eggs in the male' s pouch to develop. During this time the male avoids open water and hides in sea grass. His big pouch makes it difficult from him to swim, so the male often uses his tail to grasp a piece of sea grass. Firmly, gripping the grass, he will stay perfectly still for hours or even days. The male sea horse will change his color to blend with his surroundings and avoid being seen by predators who will try to eat him or poke holes in his pouch to get the eggs. The eggs hatch inside the male's pouch. When the babies begin moving around, the male sea horse knows it's time for them to be born. He grabs a sea grass stern with his tail and begins rocking, bending his body back and forth, this causes the opening to enlarge until wide enough for the first baby sea horse to shoot out. the father sea horse continues rocking, bending, and stretching his body so that the rest of the babies can be born. Sometimes he has to press his pouch against a rock or some stiff seaweed to force the young out. Sea horse babies are born in groups of five or more. Sometimes it takes two clays for the father sea horse to give birth to all his young. He is very tiered when it's over. Soon after giving birth to one brood, the male will approach his mat and show her his empty pouch. This tells her he is ready to receive eggs again.

单选题American universities like to think of themselves as engines of social justice, thronging with "diversity". But how much truth is there in this flattering self-image? Over the past few years Daniel Golden has written a series of stories in the Wall Street Journal about the admissions practices of America"s elite universities, suggesting that they are not so much engines of social justice as bastions of privilege. Golden shows that elite universities do everything in their power to admit the children of privilege. If they cannot get them in through the front door by relaxing their standards, then they smuggle them in through the back. No less than 60% of the places in elite universities are given to candidates who have some sort of extra "hook", from rich or alumni parents to "sporting prowess". The number of whites who benefit from this affirmative action is far greater than the number of blacks. The American establishment is extraordinarily good at getting its children into the best colleges. The former president George Bush and his rival in the election John Kerry were "C" students who would have had little chance of getting into Yale if they had not come from Yale families. A1 Gore and Bill Frist both got their sons into their alma maters (Harvard and Princeton respectively), despite their average academic performances. Universities bend over backwards to admit "legacies". Harvard admits 40% of legacy applicants compared with 11% of applicants overall. When it comes to the children of particularly rich donors, the bending-over-backwards reaches astonishing levels. Most people think of black football and basketball stars when they hear about "sports scholarships". But there are also sports scholarships for rich white students who play preppie sports such as fencing, squash, sailing, riding, golf and, of course, lacrosse. The University of Virginia even has scholarships for polo-players, relatively few of whom come from the inner cities. You might imagine that academics would be up in arms about this. Alas, they have too much skin in the game. Academics not only escape tuition fees if they can get their children into the universities where they teach. They get huge preferences as well. Boston University accepted 91% of "faculty brats" in 2003, at a cost of about $9m. Notre Dame accepts about 70% of the children of university employees, compared with 19% of "unhooked" applicants, despite markedly lower average SAT scores. Two groups of people overwhelmingly bear the burden of these policies—Asian-Americans and poor whites. Asian-Americans are the "new Jews", held to higher standards (they need to score at least 50 points higher than non-Asians even to be in the game) and frequently stigmatised for their "characters" (Harvard evaluators persistently rated Asian-Americans below whites on "personal qualities").

单选题This fall the Pew Research Center, in association with TIME, conducted a nationwide poll exploring the contours of modern marriage and the new American family. And of all the transformations our family structures have undergone in the past 50 years, perhaps the most profound is the marriage differential that has opened between the rich and the poor. In 1960 the median household income of married adults was 12% higher than that of single adults, after adjusting for household size. By 2008 this gap had grown to 41%. In other words, the richer and more educated you are, the more likely you are to marry, or to be married — or, conversely, if you're married, you're more likely to be well off. To begin the question of why the wealth disparity between the married and the unmarried has grown so much, it might be useful to take a look at the brief but illustrative marriage of golfer Greg Norman and tennis star Chris Evert, who married in June 2008 and divorced 15 months later. From all reports, their union had many of the classic hallmarks of modern partnerships. The bride and groom had roughly equal success in their careers. Being wealthy, sporty and blond, they had similar interests. This is typical of the way many marriages start. Americans are increasingly marrying people who are on the same socioeconomic and educational level. Since more women than men have graduated from college for several decades, it's more likely than it used to be that a male college graduate will meet, fall in love with, wed and share the salary of a woman with a degree. Women's advances in education have roughly paralleled the growth of the knowledge economy, so the slice of the family bacon she brings home will be substantial. On the face of it, this might explain why fewer people are married. They want to finish college first. In 2010 the median age of men getting hitched for the first time is 28.2, and for women it's 26.1. It's gone up about a year every decade since the '60s. But here's the rub. In the past two decades, people with only a high school education started to get married even later than college graduates. In 1990 more high-school-educated couples than college graduates had made it to the altar by age 30. By 2007 it was the other way around. What has brought about the switch? It's not any disparity in desire. According to the Pew survey, 46% of college graduates want to get married, and 44% of the less educated do. Promising publicly to be someone's partner for life used to be something people did to lay the foundation of their independent life. It was the declaration of adulthood. Now it's more of a finishing touch, the last brick in the edifice, sociologists believe. Marriage is the capstone for both the college-educated and the less well educated, " says Johns Hopkins' Cherlin. "The college-educated wait until they're finished with their education and their careers are launched. The less educated wait until they feel comfortable financially. " But that comfort keeps getting more elusive. "The loss of decent-paying jobs that a high-school-educated man or woman could get makes it difficult for them to get and stay married, " says Cherlin. As the knowledge economy has overtaken the manufacturing economy, couples in which both partners' job opportunities are disappearing are doubly disadvantaged. So they wait to get married.
