问题      Television—that most attractive modern technology, marked by rapid change and growth—is moving into a new era 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" can literally be interpreted as sight from a distance. Very simply put, it works in this way: through a complete 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 reconstructed 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 types. First, there is broadcast television, which reaches the masses through broad-based airwave transmission of television signals. Second, there is non-broadcast 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. 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 mostly by the broadcast networks, ABC, NBC and CBS, who have been the major suppliers of news, information, and entertainment. These giants of broadcasting have actually not only shaped television as a source of entertainment, but placed our role in this active medium as the passive viewer.
Which of the following statements can best describe TV viewers according to the passage?
选项 A、They prefer increased news coverage.
B、They do not take an active role in watching television.
C、They like to use television to reach other human beings.
D、They have more or less grown tired of television.
答案B
解析 本题为细节辨认题。文章最后提出，这些电视广播界的巨头们(指各大电视广播公司)不但使得电视成为一种娱乐的源泉，还使得我们成了消极被动的观众(这里的含义是：人们看电视时是不动脑筋的，被动地接收电视节目所传达的信息)。因此应当选择 B 项，即观众在观看电视节目时，没有扮演主动的角色，而其他几项在文中均未提及。
