For centuries men dreamed of achieving vertical flight. In 400 A. D. Chinese children play

ed with a fan-like toy that spun upwards and fell back to the earth as rotation ceased. Leonardo da Vinci conceived the first mechanical apparatus, called a "Helix", which could carry a man straight up, but this was only a design and was never tested.

The ancient dream was finally realized in 1940 when a Russian engineer piloted a strange looking craft of steel tubing with a rotating fan on top. It rose awkwardly and vertically into the air from a standing start, hovered a few feet above the ground, went sideways and backwards, and then settled back to the earth. That vehicle was called a helicopter.

Imaginations were fired. Men dreamed of going to work in their own personal helicopters. People anticipated that vertical flight transports would carry millions of passengers as do the airliners of today. Such fantastic expectations were not fulfilled. The helicopter has now become an extremely useful machine. It excels in military missions, carrying troops, guns and strategic instruments where other aircraft cannot go. Corporations use them as airborne offices, many metropolitan areas use them in police work, construction and logging companies employ them in various advantageous ways, engineers use them for site selection and surveying; and oil companies use them as the best way to make offshore and remote work stations accessible to crews and supplies. Any urgent mission to a hard-to-get-to place is a likely task for a helicopter. Among their other multitude of uses: deliver people across town, fly to and from airports, assist in rescue work, and aid in the search for missing or wanted persons.

According to the passage, people expect that______.

A．helicopters could eventually replace the airliners of today

B．their imaginations fired by the Russian engineer's invention would be realized in the future

C．their fantastic expectations about helicopters could be fulfilled by airliners of today

D．helicopters would someday be able to carry millions of people from place to place as airliners are now doing

听力原文： This incident occurred one morning outside Albert Schweitzers hospital in the

African jungle. A patient had gone fishing in another mans boat. The owner of the boat thought he should be given all the fish that were caught. Dr Schweitzer said to the boat owner, "You are right because the other man ought to have asked permission to use your boat. But you are wrong because you are careless and lazy. You merely twisted the chain of your canoe round a palm tree instead of fastening it with a padlock. Of laziness you are guilty because you were asleep in your hut on this moonlit night instead of making use of the good opportunity for fishing." He turned to the patient, "But you were in the wrong when you took the boat without asking the owners permission. You were in the right because you were not so lazy as he was and you did not want to let the moonlit night go by without making some use of it." Dr Schweitzer divided the catch among the fisherman, the boat owner, and the hospital. Questions 19 to 21 are based on the passage you have just heard. 19. Why did Dr Schweitzer settle the argument？ 20. What did Dr Schweitzer tell the men？ 21. What was the final judgment？20．

A．He told the men that both men were completely right.

B．He told the men that both men were completely wrong.

C．He told the men that each was partly right and partly wrong.

D．He told the men that one man was guiltier than the other.

Judging from recent surveys, most experts in sleep behavior. agree that there is virtually

an epidemic of sleepiness in the nation. "I can't think of a single study that hasn't found Americans getting less sleep than they ought to," says Dr David. Even people who think they are sleeping enough would probably be better off with more rest.

The beginning of our sleep-deficit crisis can be traced to the invention of the light bulb a century ago. From diary entries and other personal accounts from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9. 5 hours a night. "The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark." By the 1950s and 1960s, that sleep schedule had been reduced dramatically, to between 7.5 and 8 hours, and most people had to wake to an alarm clock. "People cheat on their sleep, and they don't even realize they're doing it," says Dr David. "They think they're okay because they can get by on 6.5 hours, when they really need 7.5, 8 hours or even more to feel ideally vigorous."

Perhaps the most merciless rubber of sleep, researchers say, is the complexity of the day. When ever pressures from work, family, friends and community mount, many people consider sleep the least expensive item on his programme. "In our society, you're considered dynamic if you say you only need 5.5 hours' sleep. If you've got to get 8.5 hours, people think you lack drive and ambition."

To determine the consequences of sleep deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier. "We've found that if you're in sleep deficit, performance suffers," says Dr David. "Short-term memory is weakened, as are abilities to make decisions and to concentrate."

People in the 18th and 19th centuries used to sleep about 5 hours a night because they had ______.

A．no drive and ambition

B．no electric lighting

C．the best sleep habits

D．something to do in the evening

The Christmas Tree

In pre-Christian Europe, people believed that trees (fruit trees and evergreens in particular) were embodiment of powerful beings. In the fourteenth and fifteenth centuries, the designated miracle play for December 25 was the story of Adam and Eve and in this play the chief prop was an apple-hung evergreen called the paradise tree. In the sixteenth century, German families began bringing evergreens into their homes during the Christmas season. By the seventeenth century, they were known as Christbaiime (Christ trees) and were being decorated with fruits, candies, cookies, candles and wafers resembling the eucharistic host.

The first Christmas trees in America were set up by German immigrants in the 1820s and the almost universal adoption of the custom dates from the 1910s. Now at Christmas time decorated trees stand in about two-thirds of American homes. The modem American tree is usually covered with colored balls and strings of colored lights. The star on top represents the Star in the East which guided the three Wise Men to Bethlehem.

Christmas is traditionally celebrated on______.

In some faraway Turkish village of Kuskoy, whistling is as important as talking. In fact,

whistling is talking because the villagers speak and sing by whistling. Kuskoy parents begin to teach their boys and girls the language of whistling about the time the children learn to talk. It is considered so important that the village school includes it as one of the subjects taught along with the Turkish language.

This art of communication has taken centuries to develop. The village of Kuskoy spreads out across two hillsides that are separated by a deep valley. The villagers had to find an easy way to communicate where their voices couldn't carry. They developed a highpitched (高音的) whistle language that could be transmitted as far as five miles through air. As a result, Kuskoy, which means "bird village" in Turkish, has come to be known as a whistler's paradise (乐园).

Whistling is so much part of everyday life in Kuskoy that men and women speak, argue (辩论), and court (求爱) in whistles. The story was recently told of a young couple who eloped (私奔). The news was sent over the "mountain telephone" by whistling. The lover's adventure (险经历) was quickly known to all the villagers.

It is little wonder, then, that the children of Kuskoy study whistling in school. Wouldn't it be fun to start the school day with a song-whistled of course!

In the story, Kuskoy is the name of ______.

A．a man

B．a country

C．a town

D．a village

Adult EducationVoluntary learning in organized courses by mature men and women is called a

Adult Education

Voluntary learning in organized courses by mature men and women is called adult education. Such education is offered to make people able to enlarge and interpret their experience as adults. Adults may want to study something*which they missed in earlier schooling, get new skills or job training, find out about new technological developments, seek better self-understanding ,or develop new talents and skills.

This kind of education may be in the form. of self-study with proper guidance through the use of libraries, correspondence courses, or broadcasting. It may also be acquired collectively in schools and colleges, study groups, workshops, clubs, and professional associations.

Modern adult education for large numbers of people started in the 18th and 19th centuries with the rise of the Industrial Revolution. Great economic and social changes were taking place: people were moving from rural areas to cities, new types of work were being created in an expanding factory system. These and other factors produced a need for further education and re-education of adults.

The earliest programs of organized adult education arose in Great Britain in the 1790s, with the founding of an adult school in Nottingham and a mechanics’ institute in Glasgow. The earliest adult education institution in the United States was founded by Benjamin Franklin and some friends in Ph People recognize that continued learning is necessary for most forms of employment today.

For example, parts of the adult population in many countries find it necessary to take part in retraining programs at work or even to learn completely new jobs. Adult education programs are springing up constantly to meet these and other needs.

A. Necessity for developing adult education

B. Early days of adult education

C. Ways of receiving adult education

D. Growth of adult education

E. Institutions of adult education

F. Definition of adult education

Text 1

Whenever Catherine Brown, a 37-year-old journalist, and her friends, professionals in their 30s and early 40s, meet at a London cafe, their favorite topic of conversation is relationships: men's reluctance to commit, women's independence, and when to have children-or, increasing-Iy， whether to have them at all. "With the years passing my chances of having a child go down, but I won't marry anyone just to have a child," says Brown. To people like Brown, babies are great-if the timing is right. But they're certainly not essential.

In much of the world, having kids is no longer a given. "Never before has childlessness been an understandable decision for women and men in so many societies," says Frank Hakim at the London School of Economics. Young people are extending their child-free adulthood by postponing children until they are well into their 30s, or even 40s and beyond.

A growing share are ending up with no children at all. Lifetime childlessness in western Germany has hit 30 percent among university-educated women, and is rapidly rising among lower-classmen. In Britain, the number of women remaining childless has doubled in 20 years.

The latest trend of childlessness does not follow historic patterns. For centuries it was not unusual for a quarter of European women to remain childless. But in the past，childlessness was usually the product of poverty or disaster, of missing men in times of war. Today the decision to have-or not have-a child is the result of a complex combination of factors, including relationships, career opportunities, lifestyle. and economics.

In some cases childlessness among women can be seen as a quiet form. of protest. In Japan, support for working mothers hardly exists. Child care is expensive, men don't help out, and some companies strongly discourage mothers from returning to work. "In Japan, it's career or child，"says writer Kaori Haishi . It's not just women who are deciding against children; according to a re-cent study, Japanese men are even less inclined to marry or want a child. Their motivations, though, may have more to do with economic factors.

46. Catherine Brown and her friends feel that having children is not _________

[ A] totally wise

[ B] a huge problem

[ C] a rational choice

[ D ] absolutely necessary
