单选题Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the drastic experiment of Frederick II in the thirteenth century, it may be hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent. All the infants died before the first year. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, in the first year of life especially, the capacity to survive is seriously affected. Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at right time, but the process is slow and hard once the critical stage has passed. Experts suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes Vowel-like sounds; at twelve months he can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1, 000 words which he can put into sentences, and at four his language differs from that of his parents in style rather than grammar. Recent evidence suggests that an infant is born with the capacity to speak. What is special about man's brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern "toy-bear" . And even more incredible is the young brain's ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways. But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child's babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child's non-verbal signals is essential to the growth and development of language.

单选题Large companies need a way to reach the savings of the public at large. The same problem, on a smaller scale, faces practically every company trying to develop new products and create new Jobs. There can be little prospect of raising the sort of sum needed from friends and people we know, and while banks may agree to provide short-terra finance, they are generally unwilling to provide money on a permanent basis for long-term projects. So companies turn to the public, inviting people to lend them money, or take a share in the business in exchange for a share in future profits. This they do by issuing stocks and shares in the business is new development if they are to serve us properly, and requires more money than is raised through the Stock Exchange. By doing so they can put into circulation the savings of individuals both at home and overseas. When the saver needs his money back he does not have to go .to the company with which he originally placed it. Instead, he sells his shares through a stockbroker (证券经纪人) to some other saver who is seeking to invest his money. Many of the services needed both by industry and by each of us are provided by the Government or by local authorities. Hospitals, roads, electricity, telephones, equipment and new development, if they are to serve us properly, require more money than is raised through taxes alone. The government, local authorities, and nationalized industries therefore frequently need to borrow money to finance major capital spending, and then too, come to the Stock Exchange. There is hardly a man or woman in this country whose job or whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one way or another this new money must come from the savings of the country. The Stock Exchange exists to provide a channel through which these savings can reach those who need finance.

单选题In a recent book entitled The Psychic Life of Insects, Professor Bouvier says that we must be careful not to credit the little winged fellows with intelligence when they behave in what seems like an intelligent manner. They may be only reacting. I would like to confront the professor with an instance of reasoning power on the part of an insect which cannot be explained away in any other manner. During the summer of 1899, while I was at work on my doctoral thesis, we kept a female wasp at our cottage. It was more like a child of our own than a wasp, except that it looked more like a wasp than a child of our own. That was one of the ways we told the difference. It was still a young wasp when we got it (thirteen or fourteen years old) and for some time we could not get it to eat or drink, it was so shy. Since it was a female we decided to call it Miriam, but soon the children's nickname for it-- " Pudge" --became a fixture, and "Pudge" it was from that time on. One evening I had been working late in my laboratory fooling around with some gin and other chemicals, and in leaving the room I tripped over a nine of diamonds which someone had left lying on the floor and knocked over my card index which contained the names and addresses of all the larvae worth knowing in North America. The cards went everywhere. I was too tired to stop to pick them up that night, and went sobbing to bed, just as mad as I could be. As I went, however, I noticed the wasp was flying about in circles over the scattered cards. "Maybe Pudge will pick them up," I said half laughingly to myself, never thinking for one moment that such would be the case. When I came down the next morning Pudge was still asleep in her box, evidently tired out. And well she might have been. For there on the floor lay the cards scattered all about just as I had left them the night before. The faithful little insect had buzzed about all night trying to come to some decision about picking them up and arranging them in the boxes for me, and then had figured out for herself that, as she knew practically nothing of larvae of any sort except wasp larvae, she would probably make more of a mess of rearranging them than if she had left them on the floor for me to fix. It was just too much for her to tackle, and, discouraged, she went over and lay down in her box, where she cried herself to sleep. If this is not an answer to Professor Bouvier's statement, I do not know what is.

单选题Brazil has become one of the developing world's great successes at reducing population growth--but more by accident than design. While countries such as India have made joint efforts to reduce birth rates, Brazil has had better result without really trying, says George Martine at Harvard. Brazil's population growth rate has dropped from 2.99% a year between 1951 and 1960 to 1.93% a year between 1981 and 1990, and Brazilian women now have only 2.7 children on average. Martine says this figure may have fallen still further since 1990, an achievement that makes it the envy of many other Third World countries. Martine puts it down to, among other things, soap operas (通俗电视连续剧) and instalment (分期付款) plans introduced in the 1970s. Both played an important, although indirect, role in lowering the birth rate. Brazil is one of the world's biggest producers of soap operas. Globo, Brazil's most popular television network, shows three hours of soaps six nights a week, while three others show at least one hour a night. Most soaps are based on wealthy characters living the high life in big cities. "Although they have never really tried to work in a message towards the problems of reproduction, they describe middle and upper class values- not many children, different attitudes towards sex, women working," says Martine. "They sent this image to all parts of Brazil and made people conscious of other patterns of behavior and other values, which were put into a very attractive package." Meanwhile, the instalment plans tried to encourage the poor to become consumers. "This 1ed to an enormous change in consumption patterns and consumption was in compatible (不相容的) with unlimited reproduction," says Martine.

单选题Passage Three We sometimes hear that essays are an old-fashioned form, that so-and-so is the "last essayist", but the facts of the marketplace argue quite otherwise. Essays of nearly any kind are so much easier than short stories for a writer to sell, so many more see print, it's strange that though two fine anthologies (collections) remain that publish the year's best stories, no comparable collection exists for essays. Such changes in the reading public's taste aren't always to the good, needless to say. The art of telling stories predated even cave painting, surely; and if we ever find ourselves living in caves again, it (with painting and drumming) will be the only art left, after movies, novels, photography, essays, biography, and all the rest have gone down the drain — the art to build from. Essays, however, hang somewhere on a line between two sturdy poles: this is what I think, and this is what I am. Autobiographies which aren't novels are generally extended essays, indeed. A personal essay is like the human voice talking, its order being the mind's natural flow, instead of a systematized outline of ideas. Though more changeable or informal than an article or treatise, somewhere it contains a point which is its real center, even if the point couldn't be uttered in fewer words than the essayist has used. Essays don't usually boil down to a summary, as articles do, and the style of the writer has a "nap" to it, a combination of personality and originality and energetic loose ends that stand up like the nap (绒毛) on a piece of wool and can't be brushed flat. Essays belong to the animal kingdom, with a surface that generates sparks, like a coat of fur, compared with the flat, conventional cotton of the magazine article writer, who works in the vegetable kingdom, instead. But, essays, on the other hand, may have fewer "levels" than fiction, because we are not supposed to argue much about their meaning. In the old distinction between teaching and storytelling, the essayist, however cleverly he tries to conceal his intentions, is a bit of a teacher or reformer, and an essay is intended to convey the same point to each of us. An essayist doesn't have to tell the whole truth and nothing but the truth, he can shape or shave his memories, as long as the purpose is served of explaining a truthful point. A personal essay frequently is not autobiographical at all, but what it does keep in common with autobiography is that, through its tone and tumbling progression, it conveys the quality of the author's mind. Nothing gets in the way. Because essays are directly concerned with the mind and the mind's peculiarity, the very freedom the mind possesses is conferred on this branch of literature that does honor to it, and the fascination of the mind is the fascination of the essay.
