British newspapers are among the oldest and most famous in the world. But recently big changes have seen these traditional publications try to fit the modern world. After 221 years The Times (《泰晤士报》) has changed its size to become much smaller. In fact the paper has cut its size in half from a broadsheet to tabloid.In Britain the newspaper market is divided between the larger broadsheets and the smaller tabloids. These terms refer to the size of the papers’ pages but there is also a clear difference in content. Broadsheets such as the Times the Guardian (《卫报》) and Daily Telegraph (《每日电讯报》) are serious papers. They cover a broad range of political economic and international issues. Their stories are also reasonably long and use quite formal language.Tabloids have far more stories about less serious issues such as celebrities’（名人） love lives. Their stories are shorter and use more language. Tabloids often have bigger pictures. Britain’s best-selling newspaper the Sun is a tabloid and has a naked (的) girl on page three every day. By changing to the size of a tabloid the Times is following in the footsteps of a less famous broadsheet paper the Independent (《独立报》). It changed to tabloid last year and saw its sales increase greatly. Although both papers have switched to the smaller size the content of the papers has remained the same. They are both still serious papers. The two papers claim that people find the smaller size easier to handle when they travel to work on the bus or the train in the morning. Instead of calling the new style of their paper tabloid the paper says its new size is “compact” (紧凑型).4. According to the passage we can infer the main reason for The Times' changing into the tabloid is that_____D. it is unlikely to stay in business if it does not change.
