     Almost every family in America or England buys at least one copy of a newspaper every day. Some

people buy as many as two or three different papers.

     Why do people read newspapers?

     Newspapers supply us with news about events in our hometowns, in our country and in other parts

of the world. Today we can read about important things that took place in foreign countries on the same

day they happened, even in countries far away. But hundreds of years ago, news of things took months

or even years to travel from one country to another. In those times, news was often passed from one

person to another andnever entirely true. Newspapers today supply us with more than just what

happened in our country or in other countries.  If we want to know what the weather will be like, we

can read the weather reports. If we want to find out what films are being shown, or what plays or

concerts we can go to we can look in the newspapers.

     In many countries people put notices in newspapers if they are trying to get a job, hunting for a house

or rooms that they can rent, or even when looking for a person who is lost.
