问题     Because of computers and cable television, the members of the audience will soon be more than watchers. They will be able to do more than choose their programs. They will also be able to give feedback on them. Two-way TV is not a dream. The hardware for such a two-way system already exists.
    One experimental group of cable-television watchers is called Qube in Columbus, Ohio. Qube has thirty channels. Members pay for what they watch. The choice of programs includes everything from sports to children’s shows, from TV games to anthropology. Most importantly, however, the viewers can talk back. A book-sized box of buttons makes it possible. For example, after a program, the announcer might ask for the opinion of the audience. The audience can respond by pushing buttons. An electronic signal goes to a bank of computers at the Qube station. Almost instantly, the data are analyzed, and the viewers see the results on their TV sets.
    A nationwide Qube system would have many uses. Government leaders could use it to get feedback from the people. It could even be used for voting. Furthermore, teachers in television classrooms could communicate with their unseen students. A television communication system would have a great influence on a country. For example, after a talk about a new product, an announcer could ask the audience for opinions. Would they buy the product? During a talk by a government leader, the announcer could ask the audience to talk back. The leader would know whether the audience believed him or not.
    The communication-computer system is possible because of glass. The same material that is used in windows can carry information. Glass strings as fine as hair are being used in telephone wires. One glass string, which now carries only telephone signals, could connect a house to a central computer bank. Many different kinds of information could also travel on it. All of the telephone messages, a number of TV shows, and computer services could flow through the glass at the same time. The home TV screen could act as a computer cathode ray tube. It could give any information that had been stored in it. For example, instead of an advertisement in the newspaper, a supermarket could put an ad on the computer. The person at home could ask the system for the ad, read it, and other groceries all at one time. The television set could connect a person to all other parts of the world. [br] The nationwide Qube system would emphasize
选项 A、the influence of watchers.
B、how to serve the watchers better.
C、the development of TV programs.
D、serving the public instead of individuals.
答案 A
解析 根据nationwide Qube system定位到第3段。该段主要讲了“Qube”的多种用途。政府获取信息，主持人征求意见等，可见该系统强调的是观众的参与度，充分利用他们的反馈所产生的影响，由此可见，本题应选A。D最具干扰性，该段中的government，country等词让人觉得全国性的“Qube”系统注重宏观服务，但是该段提到的“与看不见的学生交流”、“征求观众的意见”等都表现出这个系统注重对观众个人的服务，故排除D。
