问题     Television that most pervasion and persuasive of modern technologies, 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.
    Very simply put, television works in this way: through a sophisticated system of electronics, television provides the capability of converting an image 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.
    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 one broadcast television, which provides for the needs of individuals or specific interest groups through controlled transmission techniques.
    Traditionally, we are most familiar with broadcast television; ABC, NBC and CBS have been the major purveyors of news,information, and entertainment. But now, in addition, we have CNN, Cable News Network, the first global TV news company. With its advent, the very definition of news was rewritten from something that has happened to something that is happening at the very moment you are hearing of it. In 1991 ,one of the most eventful years of this century, the world witnessed the dramatic and transforming impact of live televised news coverage on the latest developments. For turning viewers in 150 countries into instant witnesses of history, whereby influencing the dynamic of events, Robert Edward Turner president of CNN, was Time’s Man of the Year for 1991.

选项 A、For his commitment to reshape our lives and our world.
B、For making CNN a powerful tool to reach other human beings in the"global village".
C、For introducing CNN as a major purveyor of news information.
D、For introducing"simultaneous happening"to news coverage with a vast influence on critical events of the year.

解析 因果关系题。从文章最后一段中可以知道，1991年是发生了很多重大事件的一年，通过电视媒体，我们让全世界150多个国家见证了这一重大的历史时刻。可见正是由于媒体给予的“同一时刻发生”，才使得1991年成为史上最重要的一年。
