Glasswalled skyscrapers can be especially wasteful. The heat loss (or gain)through a wall of halfinch plate glass is more than ten times that through a typical masonry wall filled with insulation board. To lessen the strain on heating and airconditioning equipment, builders of skyscrapers have begun to use doubleglazed panels of glass, and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain. However, mirrorwalled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings. Skyscrapers put a severe strain on a city39。s generosity. His contributions of more than five million dollars established 2,500 libraries in small munities throughout the country and formed the nucleus of the public library system that we all enjoy today. 08 American Revolution The American Revolution was not a sudden and violent overturning of the political and social framework, such as later occurred in France and Russia, when both were already independent nations.

According to this vies tales (about the hunt, war, or other feats) are gradually elaborated, at first through the use of impersonation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely related theory traces theater to those dances that are primarily rhythmical and gymnastic or that are imitations of animal movements and sounds. 06 Television Televisionthe most pervasive and persuasive of modern technologies, marked by rapid change and growthis moving into a new era, an era of extraordinary sophistication and versatility, which promises to reshape our lives and our world. It is an electronic revolution of sorts, made possible by the marriage of television and puter technologies. The word television, derived from its Greek (tele: distant) and Latin (visio: sight) roots, can literally be interpreted as sight from a distance. Very simply put, it works in this way: through a sophisticated system of electronics, television provides the capability of converting an image (focused on a special photoconductive plate within a camera) into electronic impulses, which can be sent through a wire or cable. These impulses, when fed into a receiver (television set), can then be electronically reconstituted into that same image. Television is more than just an electronic system, however. It is a means of expression, as well as a vehicle for munication, and as such bees a powerful tool for reaching other human beings. The field of television can be divided into two categories determined by its means of transmission. First, there is broadcast television, which reaches the masses through broadbased airwave transmission of television signals. Second, there is nonbroadcast television, which provides for the needs of individuals or specific interest groups through controlled transmission techniques. Traditionally, television has been a medium of the masses. We are most familiar with broadcast television 背 誦 篇 章 4 because it has been with us for about thirtyseven years in a form similar to what exists today.

His success resulted in part from his ability to sell the product and in part from his policy of expanding during periods of economic decline, when most of his petitors were reducing their investments. Carnegie believed that individuals should progress through hard work, but he also felt strongly that the wealthy should use their fortunes for the benefit of society. He opposed charity, preferring instead to provide educational opportunities that would allow others to help themselves. He who dies rich, dies disgraced, he often said. Among his more noteworthy contributions to society are those that bear his name, including the Carnegie Institute of Pittsburgh, which has a library, a museum of fine arts, and a museum of national history. He also founded a school of technology that is now part of CarnegieMellon University. Other philanthrophic gifts are the Carnegie Endowment for International Peace to promote understanding between nations, the Carnegie Institute of Washington to fund scientific research, and Carnegie Hall to provide a center for the arts.
