单选题A Life with Birds For nearly 17 years David Cope has worked as one of the Tower of London's Yeoman Warders, (51) known to tourists as Beefeaters.

The Tower of London is famous (54) its ravens, the large black birds which have lived there for over three centuries.

单选题Early or Later Day Care The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive "attachment" period from birth to three may scar a child's personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion. Firstly, anthropologists point out that the insulated love affair between children and parents found in modem societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, the father and mother of a child did not rear their infant alone--far from it. Secondly, common sense tells us that day care would not be so widespread today if parents, care-takers found children had problems with it. Statistical studies of this kind have not yet been carded out, and even if they were, the results would be certain to be complicated and controversial. Thirdly, in the last decade there have been a number of careful American studies of children in day care, and they have uniformly reported that day care had a neutral or slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue. But Bowlby's analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.

Because the men are new at the game, they don't hesitate to discuss the fat problem incessantly. However women of the same age do not discuss the fat problem, especially not in mixed company. They prefer to face the problem with quiet dignity. Discussing the problem might only draw attention to some stray body part that may be successfully tucked away under an article of clothing. The age at which a man begins to explore the fat problem can vary. The actual problem can manifest itself in the early 30's, but broad-range discussion usually starts later. There are early nonverbal symptoms. I've watched the rugged journalist who shares my apartment sneak by with a Diet Coke. His shirts are no longer neatly tucked in to display a trim waist. Recently he has begun to verbalize his anxiety. He tells me, with a sheepish grin, that he is taking his suits to Chinatown to have them "tailored". Still-older men have lost their dignity and rattle on unabashedly. Often wives and children play important roles in their fat-inspection rituals. Take my oldest brother, a former college football player. His daughter says that several times a day he will stand at attention and call out, "Fat, medium or thin?" She knows the correct answer: medium. Thin would be an obvious stretch, and fat may not get her that new video. According to his wife, he stands in front of the mirror in the morning(before the day's meals take their toll),puts his hands behind his head and lurches into a side bend, then clutches the roll that has developed and says, "Am I getting fatter? " His wife is expected to answer, "You look like you may have lost a few pounds." And then there are the ex-husbands a pitiful group. They are extremely vocal. When I go to the movies with one, he confides that he is suffering from great hunger because he is dieting. He hasn't eaten since the pancakes and sausages he wolfed down that morning. He pauses in his monologue while he buys his popcorn. After the movie, we sprint to a restaurant, where he again pauses to devour a basket of bread. Before he orders his chaste salad and soup, he grows plaintive. Do I think he's fat?

单选题How Ford Turn Out Cars When it comes to singling out those who have made a difference in all our lives,you cannot overlook Henry Ford. A historian a century from now might well conclude that it was Ford who most influenced all manufacturing, everywhere, even to this day, by introducing a new way to make cars--one, strange to say, that originated in slaughterhouses. Back in the early 1900's,slaughterhouses used what could have been called a "disassembly line. "Ford reversed this process to see if it would speed up production of a part of an automobile engine called a magneto. Rather than have each worker completely assemble a magneto, one of its elements was placed on a conveyer, and each worker, as it passed, added another component to it, the same one each time. Professor David of the University of Delaware, an expert on industrial development ,tells what happened: "The previous day,workers carrying out the entire process had averaged one assembly every 20 minutes. But on that day,on the line,the assembly team averaged one every 13 minutes and 10 seconds per person. " Within a year,the time had been reduced to five minutes. In 1913,Ford went all the way. Hooked together by ropes, partially assembled vehicles were towed past workers who completed them on piece at a time. It wasn't long before Ford was turning out several hundred thousand cars a year,a remarkable achievement then. And so efficient and economical was this new system that he cup the price of his cars in half,to $ 260,putting them within reach of all those who, up until that time, could not afford them. Soon, auto makers the world over copied him. In fact, he encouraged them to do so by writing a book about all of his innovations, entitled Today and Tomorrow. The Age of the Automobile has arrived. Today, aided by robots and other forms of automation,everything from toasters to perfumes are made on assembly lines.

单选题Play Play is the principal business of childhood, and in recent years research has shown the great importance of play in the development of a human being. From earliest infancy, every child needs opportunity and the right materials for play, and the main tools of play are toys. Their main function is to suggest, encourage and assist play. To succeed in this they must be good toys, which children will play with often, and will come back to again and again. Therefore it is important to choose suitable toys for different stages of a child's development. In recent years research on infant development has shown that the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life. So a baby's ability to profit from the right play materials should not be underestimated. A. baby who is encouraged and stimulated, talked to and shown things and played with, has the best chance of growing up successfully. In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toy should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability. Bricks and jigsaws(七巧板)and construction toys; painting, scribbling(涂鸦) and making things; sand and water play; toys for imaginative and pretending play; the first social games for learning to play and get on with others. Bt the third stage of play development-from five to seven or eight years-the child is at school. But for a few more years play is still the best way of learning, at home or at school. It is easier to see which type of toys the chills most enjoys. Until the age of seven or eight, play and work mean much the same to a child. But once reading has been mastered, then books and school become the main source of learning. Toys are still interesting and valuable, they lead on to new hobbies, but their significance has changed-to a child of nice or ten years, toys and games mean, as to adults, relaxation and fun.
