【简答题】
Directions: Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need. A. Manufacturing industry in information economy B. News in the age of information C. Argument about individual accounts and their reliability D. Be your own investigative journalist E. Don’t believe everything you read in the newspapers. F. Information is presented in an entertaining way. 小题1:______ With the arrival of the age of “information economy”, intellectual work is becoming a more important source of wealth than manufacturing. Organizations in all walks of life are doing more to spread their information. So people of the Public Relations are hired to speak for them. A lot of our news is actually collected from press releases and reports of events intentionally staged for journalists. In the information age, journalists spend their time, not investigating, but passing on the words of a spokesperson. 小题2:______ There is a joke in the novel Scoop about the newspaper’s owner, Lord Copper. The editors can never disagree with him. When he’s right about something they answer “definitely”, and when he’s wrong they say “to some extent, Lord Copper.” It seems reasonable to suppose that, in the real world, the opinions of such powerful people still influence the journalists and editors who work for them. 小题3:______ In countries where the news is not officially controlled, it is likely to be provided by commercial organizations who depend on advertising. The news has to attract viewers and maintain its audience ratings. I suspect that some stories get air-time just because there happen to be exciting pictures to show. In Britain, we have the tabloid newspapers which millions of people read simply for entertainment. There is progressively less room for historical background, or statistics, which are harder to present as a sensational story. 小题4:______ There is an argument that with spreading access to the internet and cheap technology for recording sound and images we will all be able to find exactly the information we want. People around the world will be able to publish their own eye-witness accounts and compete with the widely-accepted news-gatherers on equal terms. But what it will mean also is that we’ll be subjected to a still greater amount of nonsense and lies. Any web log may contain the latest information of the year, or equally, a made-up story that you will never be able to check. 小题5:______ Maybe the time has come to do something about it, and I don’t just mean changing your choice of TV channel or newspaper. In a world where everyone wants you to listen to their version, you only have two choices: switch off altogether or start looking for sources you can trust. The investigative journalist of the future is everyone who wants to know the truth.
