Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.
听力原文： In Britain there are 11 national daily newspapers and most people read one of them every day. There are two kinds of newspaper. One is large in size and has many detailed articles about national and international events. These newspapers are called the serious papers or the quality papers. The other kind, called the tabloids, are smaller in size, have more pictures, often in color, and short articles, often about less important events or about the private lives of well-known people. Although some people disapprove of tabloids, more people buy them than buy the serious newspapers. The Sun, for example, which is a tabloid, is the biggest-selling newspaper in Britain. The tabloids are sometimes called the gutter press. And in 1997, some photograph reporters of the tabloids were said to be involved in the tragic death of Princess Diana in France and they were criticized as Paparazzi by the public.
Most national newspapers in Britain express a political opinion and people choose the newspaper that they read according to their own political beliefs. Most of the newspapers are right-wing which means they support the Conservative Party. These are the Daily Telegraph, which is the serious newspaper, the Daily Express, Daily Mail, Daily Star, the Sun and Today, which are all tabloids. Of the other serious newspapers, The Times, the oldest newspaper in Britain, did not formerly have one strong political view but it is now more right-wing. The Independent does not support any political party, and neither does the Financial Times, which concentrates on business and financial news. The Daily Mirror is the voice of the Labor Party.

UN officials pledged Thursday to bridge, the world's digital divide, bringing computers and Internet training to poorer countries before they fall further behind in technology and wealth. The Digital Service Corps initiative expands on a University of Pennsylvania pilot that sent three professors and 27 students to the West African country of Mall last spring. Four countries will be selected for visits in December.
In partnering with the private Global Technology Organization, the UN Office for Projects Services wants to reduce the gap separating nations with good technology from those without. "There are more Web sites originating here in New York than in all of Africa," said Reinhart Helmke, executive director of the UN agency. "There are more Web sites originating in Finland than in all of Latin America and the Caribbean." Helmke said the digital divide would be better described as a digital chasm. He said the global economy cannot be sustained if some countries are left out.
Neysan Rassekh, founder and president of Global Technology Organization, vowed to tackle the problem "country by country, town by town, citizen by citizen." The initiative carries no funding, however. The UN projects office, as a self-financing agency with a limited budget, will provide only management know-how: Rassekh's group, which organized the University of Pennsylvania group, plans to solicit(恳求) cash and equipment donations. For the Mall project, the university paid airfare and other expenses through fees that students pay to receive academic credit.
Eliminating the global divide won't be easy. Persuading foreign governments to buy computers instead of food can be tough, even though technology can reduce poverty and hunger in the long run, said Hafidh Chaibi, who promotes global access through the World of Knowledge Foundation in Orlando, Fla. Ernest Wilson, an international development specialist at the University of Maryland, said his research found information technology growing by 18 percent a year in developing countries, compared with 23 percent in industrialized nations. That means the gap continues to grow despite improvements through programs from the United Nations, the World Bank, the Markle Foundation and other organizations.
The UN announcement came as world leaders met at the UN Millennium Summit to discuss such challenges as peace, disarmament and access, to new technology. Over four weeks in May and June, the University of Pennsylvania volunteers set up four computer centers in Mall and trained 120 residents, mostly students and educators who could then teach others. Organizers are also setting up a Web site to help residents obtain information on education and health. The UN agency and its private partner plan to replicate that effort in 10 to 12 countries a year.
The "digital divide" as is used in the first passage refers to ______.
