carefully. Is there anything different from your notebook paper? This kind of
paper feels as soft as your notebook paper. It’s also easy to write on. But do
you know, this kind of paper is made from stone?

Newspapers are very important in our daily life. Many people begin their day by reading the paper. In this way they learn what is going on in the world. Sometimes, however, they didn't have the time to read the news carefully and must be pleased with a quick look at the front page. At other times they may be in such a hurry that they have time only to have a quick look at the headlines(标题).
There are newspapers to please every reader. In big cities there are many types with several different editions every day. In some towns there are fewer newspapers and perhaps only one edition each day. In some places the paper is printed weekly.
Most papers have several editions(版本), especially on Sundays when the edition is larger than usual. There are, besides the front page with the most important news, the sports news, the amusement(娱乐)page, a business page and so on.
