【答案解析】Newspapers are generally believed to be the symbol of the conscience of the nation which monitors the government behavior. But today, under the great pressure from the Internet, they have to cut costs by spending less on journalism. Many are also trying to attract younger readers by shifting the mix of their stories towards entertainment, lifestyle and subjects that may seem more relevant to people's daily lives than international affairs and politics are. They are trying to create new business on-and offline. And they are investing in free daily papers, which do not use up any of their meager editorial resources on uncovering political corruption or corporate fraud. In a word, newspapers gradually lose their status as the "Fourth Estate" which guards the national conscience.
