单选题1970 was World Conservation Year. The United Nations wanted everyone to know that the world is in danger. They hoped that governments would act quickly in order to "conserve" nature. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland. But now only 866 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and water, and everything that grows and lives. We can't live without these things either. If we continue like this, we shall destroy ourselves. What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometres of their river. Young people may hear conservation through a record called "No One's Going to Change Our World". It was made by the Beetles, Cliff Richard and other singers. The money from it will help to conserve wild animals.

单选题Questions 16-20 are based on the following passage: Beijing's top hotels are fielding scores of calls from foreigners and Chinese people eager to book rooms during the 2008 Olympic Games in the Chinese capital. The luxurious and recently-renovated Beijing Hotel said it had received nearly 100 telephone inquiries from people wanting to book rooms during the Games since Beijing won its bid to host the event. "Out of these people, foreigners make up 30 to 40 per cent, including people calling from the United States and Europe," a hotel sales manager surnamed Song said. Minutes before the decision by the International Olympic Committee (IOC) was announced in Moscow, the hotel had already received 50 to 60 such phone calls from would-be game-goers gambling on the result. Domestic callers have mainly come from the southern provinces of Guangdong and Fujian. Song said the hotel was not taking reservations, but only noting down names of callers, because seven years was too far in advance. The hotel also may be used by the IOC and would then need to set aside rooms for IOC members, he said. Beijing will have more than 800 hotels with star ratings before the Olympic Games in 2008. The city currently has 20 five-star hotels, 34 four-star hotels and 338 other hotels with lower ratings. About 70 hotels will be designated to accommodate athletes and Olympic officials during the Games.

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.
