     Hundreds of years ago, news was carried from place to place by people on foot or by horse. It took

days, weeks and sometimes months for people to receive news. Now it is possible to send words and

pictures around the world in seconds. Billions of people learn about news stories of their own country

and all over the world every day, either by watching TV or reading newspapers.

     Newspapers have been an important part of everyday life since (自从) the 18th century (世纪).

Many countries have hundreds of different newspapers. How do newspaper editors decide which news

stories to print? Why do they print some stories and not others? What makes a good newspaper story?   

     Firstly, it is important to report new stories. TV stations can report news much faster than newspapers. Yet, newspapers give more about the same story. They may also look at the story in another way, or

they may print completely (完全地) different stories to those on TV.

     Secondly, a news story has to be interesting and unusual. People don't want to read stories about

everyday life As a result (结果), many stories are about some kind of danger and seem(似乎) to be

"bad" news. For example, newspapers never print stories about planes landing safely, instead they print

stories about plane accidents (事故).

     Another factor (因素) is also very important in many news stories. Many people are interested in news

in foreign countries, but more prefer(更喜欢) to read stories about people, places and events (事件) in

their own country. So the stories on the front page in Chinese newspapers are usually very different from

the ones in British, French and American newspapers.
