interests me most are the things happening at schools.

    School news is just one kind of news story in newspapers. There is also news from around the world一from

international problems to pop stars.

    If you read the newspaper carefully, you'll find there're different kinds of articles on the pages:

    News stories

    These stories are about events. Reporters try to show all sides 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

convince readers that the stories are true. Teens has lots of news stories on the news page and front page. When

you read stories, you hear about the facts; not the writers' ideas.

    Opinion (观点) writing

their own opinions. Writers choose only the facts that help back up (支持) their ideas. They are trying to

persuade (说服) readers. This is usually the kind of story that gets people thinking. Go to "Speak Out" on page

interested in their products (产品)! People have to pay to put advertisements in newspapers
