A few years ago it was common to speak of a generation gap between young people and their elders. Parents said that children did not respect and listen to them, while children said that their parents did not understand them at all. What had gone wrong？ Why had the generation gap suddenly appeared？ Actually, the generation gap has been around for a long time. Many people argue that it is built into every part of our society. One important cause of the generation gap is .the opportunity that young people have to choose their own ways of life. In a more traditional society, when children grow up, they axe expected to live in the same place as their parents, to marry people that their parents know and like, and often to continue the family jobs. In our society, young people often travel great distances for their education, move out of the family at an early age, marry or live with people whom their parents have never met, and choose jobs different from those of their parents. In our society, parents often expect their children to do better than they did, to find better jobs, to make more money and to do all the things that they were unable to do. Often, that is another cause of the gap between them. Often, they discover that they have very little in common with each other. Finally, the speed at which changes take place in our society is the third cause of the gap between the generations. In a traditional culture, senior people axe valued for their knowledge, but in our society the knowledge of a lifetime may become out of date. The young and the old seem to live in two very different worlds, separated by different skills and abilities. No doubt, the generation gap will continue in American life for some time.The first paragraph tells that （）.

From the beginning rivers have played an important part in the life of man. Man of the ear

liest times used the rivers as a means of traveling. Today rivers still serve as a great waterway for the transport and people.

In ancient times, man settled near rivers or on river banks and built up large empires.

Water is the Nature's most precious gift to man. Man needs water to irrigate his crops, to cook and to wash. In nations all over the world rivers mean life and wealth. They feed and clothe the nations around them.

Water is also a source of energy and power. Man constructs huge dams across the river to control the water for irrigation and get the energy needed to drive generators. The electrical power is then directed to homes, cities, factories and television stations.

Man uses water each day. His main source of water comes from reservoirs, which in turn get their water from the rivers.

Rivers also bring down soil and minerals from the mountains and deposit them on the plains building up rich river deltas for raising plants and crops. Fresh water life in rivers or in lakes fed by them provide man with food.

In a small way rivers help to keep man in good health and provide for his amusements. Various forms of water sports keep man strong and healthy.

Rivers have run on this earth long before man. Man's future ability to live is uncertain, but rivers will flow on forever.

Rivers have been important to man______.

A．since the last century

B．for a very long time

C．since a few hundred years ago

D．since a few years ago

［A］ For example, the Moche lords of Sipán in coastal Peru were buried in about AD

400 in fine cotton dress and with exquisite ornaments of bead, gold, and silver. Few burials rival their lavish sepulchres. Being able to trace the development of such rituals over thousands of years has added to our understanding of the development of human intellect and spirit.

［B］ By 40,000 years ago people could be found hunting and gathering food across most of the regions of Africa. Populations in different regions employed various technological developments in adapting to their different environments and climates.

［C］ Archaeological studies have also provided much information about the people who first arrived in the Americas over 12,000 years ago.

［D］ The first fossil records of vascular plants—that is, land plants with tissue that carries food—appeared in the Silurian period. They were simple plants that had not developed separate stems and leaves.

［E］ Laetoli even reveals footprints of humans from 3.6 million years ago. Some sites also contain evidence of the earliest use of simple tools. Archaeologists have also recorded how primitive forms of humans spread out of Africa into Asia about 1.8 million years ago, then into Europe about 900,000 years ago.

［F］ One research project involves the study of garbage in present-day cities across the United States. This garbage is the modern equivalent of the remains found in the archaeological record. In the future, archaeologists will continue to move into new realms of study.

［G］ Other sites that represent great human achievement are as varied as the cliff dwellings of the ancient Anasazi (a group of early Native Americans of North America) at Mesa Verde, Colorado; the Inca city of Machu Picchu high in the Andes Mountains of Peru; and the mysterious, massive stone portrait heads of remote Easter Island in the Pacific.

Almost every family buys at least one copy of a newspaper every day, Some people subscribe

to as many as two or three different newspapers. But why do people read newspapers？

Five hundred years ago, news of important happenings--battles lost and won, kings or rulers overthrown or killed--took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in our newspapers of important e vents that occur in faraway countries on the same day they happen.

Apart from supplying news from all over the world, newspapers give us a lot of other useful in formation. There are weather reports, radio, television and film guides, book reviews, stories, and, of course, advertisements. There are all sorts of advertisements. The bigger ones are put in by large companies to bring attention to their products. They pay the newspapers thousands of dollars for their advertising space, but it is worth the money, for news of their products goes into almost every home in the country. For those who produce newspapers, advertisements are also important. Money earned from advertisements makes it possible for them to sell their newspapers at a low price and still make a profit.

第11题

Visitors from space may have landed on our planet dozens, even hundreds of times during th

e long, empty ages while Man was still a dream of the distant future. Indeed, they could have landed on 90 percent of the earth as recently as two or three hundred years ago, and we could never have heard of it. If one searches through old newspapers and local records, one can find many reports of strange incidents that could be interpreted as visits from outer space. A stimulating writer, Charles Fort, has made a collection of UFO sighting in his book! One is tempted to believe them more than any modern reports, for the simple reason that they happened long before anyone had ever thought of space travel. Yet at the same time, one can't take them too seriously, for before scientific education was widespread, even sightings of meteors, comets, auroras, and so on, gave rise to the most incredible stories, as they still do today.

According to the passage, visitors from space may have landed on the earth ______.

A．long before man had dreamed of it

B．long before there were human beings

C．in the last few hundred years

D．after the space age began
