案例分析题The Eskimos have developed a capacity to live peacefully with one another. They have not had a strict system of landownership, one of the universal causes of conflict. They have evolved a system of food-sharing among families that makes the preservation of life possible. The absolute necessity of creating this safeguard against starvation has strengthened bonds between neighbors. Almost every traveler has noted the Eskimos" friendliness and good humor toward strangers and among themselves. In a country where agriculture is impossible they have been forced to spend their energies in food- gathering rather than warfare. If one family disagreed with another, the usual solution was for that family to pick up its few possessions and go elsewhere. In the vast unused land, moving presented almost no problem.The practice of infanticide, and suicide among the old people, seems to have been a factor of survival in times of food scarcity. The size of the family was controlled to some extent by the ability of the father as a hunter and by the abundance ofgame(猎物) in the area.Marriage was a very serious and lifelong bond among Eskimos; in order to choose a permanent and compatible mate a number of trial marriages were permitted, each lasting perhaps half a year. During the trial period a couple usually lived with the girl"s parents and the young man hunted exclusively for his future father-in-law. If a child was born as a result of an unsuccessful trial marriage it was adopted by relatives or friends. Children are often given out for adoption in the Eskimos society and are eagerly adopted by other families, for the Eskimos" camp andnomad(游牧民族的) group represent a kind of extended family.Polygamy(一夫多妻制) was occasionally practiced by the most successful hunters, but usually to protect a widow or a girl who had lost her father. The Eskimos live peacefully with one another because of ______.
案例分析题For thousands of years, people thought of glass as something beautiful to look at. Only recently have they come to think of it as something to look through. Stores display their goods in large glass windows. Glass bottles and jars that hold food and drink allow us to see the contents. Glass is used to make eyeglasses, microscopes, telescopes, and many other extremely useful and necessary objects.Until the Second World War, most of the glass used for optical instruments was imported from Europe. However, during the war Americans could not get European glass, and they were forced to make their own. As a result, new kinds of glasses were developed that had been previously unknown. These new effects were achieved by mixing other chemical elements with the sand. Some of these new glasses are very strong and can resist many kinds of shocks. Legend has it that a very hard glass was invented by a Roman who showed his discovery to the Emperor. When the Emperor saw the glass he feared that it would become more valuable than gold and silver, making his treasure worthless. Therefore, he had the glassmaker killed, and the secret was not discovered again for hundreds of years.In the present century, safety glass was invented for use in modern cars and planes. Safety glass is made by placing a layer of plastic between two layers of plate glass. When the outside layer of glass is broken, the pieces do not scatter and injure people. Some glass of this type is strong enough to resist bullets.Although in recent years plastics have replaced glass under conditions where glass might be easily broken, there are new uses being developed, for the greatest advantage of glass is that its component parts are inexpensive and can be found all over the world. With the passage of time, glass ______.
