Computers are very important to modern life. Many people think that in the future computers will be used in lots of fields in our life. It is thought that we won't have to go shopping because we can get most things on the Internet. There will be no more books because we can get all texts from computers. The Internet will be used to play games, watch films and buy food. Most telephone calls will be made by computers, too. ??? Some people are glad about these new ways of shopping and communicating. Others do not think that computers will replace 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 by 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. Computerized books will be used more and more. ??? Is the 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. It is also unlikely that many people will want to read large texts on our computers. Paper books will perhaps be more friendly. Maybe computers won't change these two habits.
