 Computers are very important to modern life. Many people think that in the future computers will be used much more in everyday life. It is thought that we won't have to go shopping,because we will be able to get most things on the Internet. There will be no more books because we will be able to get all texts from computers. The Internet will be used to play games, see films and buy foods. Most telephone calls will be made on computers.

  Some people are glad about these new ways of shopping and communicating. Others do not think that computers will take the place of our old ways.

Let's look at books. For example, some people think that one day we will not read books made of paper. Instead, we will buy and read books using computers. We will read texts on small pocket computers. The computers will keep many different books in them at the same time. We won't need to turn lots of pages and paper will be saved.

  Is Internet shopping such a pleasure as going to the shop? Many people say it is not. It is a pleasure to go into shops and look at things you want to buy. Also, probably, people won't like to read large texts on our computers, because paper books seem to be more friendly. Maybe computers won't change these two habits.
