问题     Television—that most pervasive(遍布的)and persuasive of modern of modern technologies, marked by rapid change and growth — is moving into a new era, and 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 "television", derived from its Greek(tele: distant)and Latin(vision: 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(光电导的)plate within a camera)into electronice impulses, which can be sent through a wire or a 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 electronics 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 reached the masses through broad-based airwave transmission of television signals. Second, there is non-broadcast television, which provided 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 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(传播者)of the news, information and entertainment. These giants of broadcasting have not only shaped television but our perception(感觉)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.
The word "put"(2nd sentence of 2nd Para.)could best be replaced by which of the following?
选项 A、expressed
B、asked
C、placed
D、inserted
答案A
解析 本题为语义分析题。very simple put意为“简单地说”。A项为“表达、表述”，B项为“询问，要求”，C项为“放”，D项为“插入”。据此可知，A项与原文意思一直，因此，A项正确。
