(1)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.
(2)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.
(3)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.
(4)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.
Which of the following can be done by Qube?
选项
A、Giving oral feedback.
B、Analyzing feedback on a computer.
C、Playing games on TV.
D、Responding by typing on a computer.
答案
A
解析
根据题干中的Qube定位到第2段。该段第5句中的talk back表明Qube有口头回应的功能,且接下来的文字也是对该功能的具体说明,因此A为本题答案。在本文中,Qube是指参加试验的用户,根据该段第4句可知用户只能看TV games,而不是在电视上打游戏,故排除C;根据最后三句可知信息反馈应是audience,数据应是由“Qube”站的计算机组负责分析的,故B、D亦排除。
