Newspapers are very important in our everyday life. Many people begin their day by reading the paper. In this way they learn what is going on in the world. But sometimes they don’t have the time to read the newspaper carefully and must be pleased with a quick look at the front page. Sometimes they may be in such a hurry that they have time only to look at the headlines quickly.

There are newspapers to please every reader. In big cities there are many kinds with several different editions every day. In small towns there are fewer newspapers and perhaps only one edition each day. Some papers in small towns have several editions, especially on Sundays. Besides the front page with the most important news, there is the sports page, the amusement page, the business page and so on.
