单选题Where you save your money often depends on what you are saving for. If you are saving to buy a dictionary or to go to a concert, then probably keep your money somewhere in your room. If you are saving for a big purchase like a mountain bike or a school trip, where would you save your money? One place to save money is the bank. Putting your money in a savings account will help your money earn more money. If you put your money in a piggy bank (猪形储蓄罐) , one year later you"ll still have the same amount of money you put in. If you put your money in a savings account, one year later, you"ll have more money than you put in. Why? When you keep your money in a bank, your money earns interest. Interest is the amount of money a bank pays you to use your money. The bank uses your money (and the money of other people, too) to loan money to people and businesses. The bank will send you a statement several times a year. A bank statement tells you how much money there is in your account. It also tells you how much interest you have earned. If you leave your money in the bank, you can watch it grow! Another way you can save money is to buy a certificate of deposit or CD. If you have some money that you don"t need to use for a long time, this is a good way to make your money grow. You can buy a CD at a bank. You agree not to use the money for a certain period of time. That period might be from six months to five years. You can"t touch your money during that time. If you do, you must pay a penalty, or fee. Since the bank is using your money for that time period, it will pay you interest. You will earn more interest with a CD than in a savings account. Can you guess why? It"s because you promise to leave your money in the bank for a certain period of time. Banks pay different rates of interest. So, you may want to compare rates in newspaper ads before buying a CD.

单选题The number of speakers of English in Shakespeare"s time is estimated to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language, as well as various levels of usage that are employed both in its spoken and written forms. It is virtually impossible to estimate the number of people in the world who have acquired an adequate working knowledge of English in addition to their own languages. The purpose for which English is learned and the situations in which such learning takes place are so varied that it is difficult to define and still more difficult to assess what constitutes an adequate working knowledge for each situation. The main reason for the widespread demand for English is its present day importance as a world language. Besides serving the infinite needs of its native speakers, English is a language in which some of the important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the dissemination of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multi-lingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for access to the scientific and technological developments in the West.

单选题The United States has historically had higher rates of marriage than those of other industrialized countries. The current annual marriage 1 in the United States—about 9 new marriages for every 1,000 people—is 2 higher than it is in other industrialized countries. However, marriage is 3 as widespread as it was several decades ago. 4 of American adults who are married 5 from 72 percent in 1970 to 60 percent in 2002. This does not mean that large numbers of people will remain unmarried 6 their lives. Throughout the 20th century, about 90 percent of Americans married at some 7 in their lives. Experts 8 that about the same proportion of today"s young adults will eventually marry. The timing of marriage has varied 9 over the past century. In 1995 the average age of women in the United States at the time of their first marriage was 25. The average age of men was about 27. Men and women in the United States marry for the first time an average of five years later than people did in the 1950s. 10 , young adults of the 1950s married younger than did any previous 11 in U.S. history. Today"s later age of marriage is 12 the age of marriage between 1890 and 1940. Moreover, a greater proportion of the population was married (95 percent) during the 1950s than at any time before 13 Experts do not agree on why the "marriage rush" of the late 1940s and 1950s occurred, but most social scientists believe it represented a 14 to the return of peace and prosperity after 15 years of severe economic 15 and war.

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.
