     Some teenagers think that newspapers are boring and only for adults. But that's not true. There are

many interesting stories in the paper. You just need to make clear what you are looking at. "I spend

about half an hour reading newspapers every day," said 15-year-old Gao Ming from Beijing. "I'm

interested in things happening at school." School news is just one kind of news story in newspapers.

There's also world news: from international problems to pop stars.

     Read the newspaper carefully, we'll find different types of articles on the pages:

     News stories - these stories are about events. Reporters try to show all points of a story to help

readers understand what happened. Reporters try to speak to as many people as possible. They also

use pictures and numbers to show the readers that the stories are true. The newspaper Teenagers has

lots of news stories on the news page and front page. When we read them, we learn more about the

facts, not the writers' ideas.

     Opinion writing - opinion writing is usually about something happening right now. But it isn't just facts.

Here writers add their own opinions to the news. Writers pick only the facts that help back up their

ideas. They make readers believe that they are telling the truth. This is usually the kind of story that gets

people thinking. Go to "Speak Out" on Page Two for an example of opinion writing in Teenagers.

     Advertisement - Don't get happy too early when you read them. Those sweet words and lovely

pictures are just ways to get us interested in their products! People have to pay to put advertisements in

newspapers!

Getting rid of dirt, in the opinion of most people, is a good thing. However, the attitudes to dirt are always changing.

In the early 16th century, people thought that dirt on the skin was a means to block out disease, and washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.

Though the belief above was long­lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ.Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?

Attitudes to dirt still differ hugely nowadays. Many first­time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary，Mary Ruebush，an American immunologist(免疫学家)，encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.
