marked by rapid change and growth-is 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 computer technologies.
The word \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 communication, and as such becomes 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 broad-based 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 because it has been with us for about thirty-seven years in a form similar to what exists today. During those years, it has been

controlled, for the most part, by the broadcast networks, ABC, NBC, and CBS, who have been the major purveyors of news, information, and entertainment. These giants of broadcasting have actually shaped not only television but our perception of it as well. We have come to look upon the picture tube as a source of entertainment, placing our role in this dynamic medium as the passive viewer.
07 Andrew Carnegie p
Andrew Carnegie, known as the King of Steel, built the steel industry in the United States, and , in the process, became one of the wealthiest men in America. 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 competitors 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. \dies disgraced,\
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 Carnegie-Mellon 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. Few Americans have been left untouched by Andrew Carnegie's generosity. His contributions of more than five million dollars established 2,500 libraries in small communities throughout the country and formed the nucleus of the public library system that we all enjoy today. 写好考博作文的几点看法

You should write about 200 words within 40 minutes.
Women play an important part in modern society. Now many women are going into professions, such as medicine, law and engineering. They comprise a large part of the workers in offices and factories. Many jobs they are engaged in are in line with their special capabilities of their sex. In addition, some of are working up to important positions which used to be held mainly by men. There are even some businesses which are run completely by women. It is obvious that women are making an outstanding contribution to the progress of modern society.
There are, however, still some people who assert that men are superior to women in many ways. In the first place, many jobs men do can hardly be done by women, who are physically not strong enough. They believe that women are the weaker sex – both physically and emotionally. Thus, women are naturally suited, much more so than men, to the performance of domestic duties. According to them, a woman’s place is within the protective environment of the home. Secondly, most of the world-famous scientists and statesmen are found to be males. Finally, the whole society seems to have always been dominated by men only. In their opinion, men should enjoy more rights than do women.
Personally, I’m firmly standing on the side of those women right defenders. Since both men and women are equally important in human activities, they
