     It would be very exciting to be a reporter on a newspaper. As soon as a reporter's boss gives him a story

to write, the reporter is on the job. He keeps his mind on what he is going to do. He does not begin writing the

story until he knows what he should find out. He must know why he should write the story.

     At times a reporter must search hard to find all of the facts he needs for a story. The facts may not be right

under his nose. To find the facts, he has to recognize important details. While gathering information for a story, he asks himself questions:Should I use this information? Is this an important fact?

     A reporter writes the story as fast as he can, so it can go right away into the newspaper. The story also

needs a headline, which tells very quickly what the news story is about and is printed bigger and blacker than

the rest of the news story.

     Every big newspaper has many reporters, because many stories are needed in the newspaper. Would you

like to be one?
