Computers are very important to modern life. Many people think that in the future we will use computers in everyday life. It is thought that we won’t have to go shopping because we will be able to get most things which are sold in shops on the Internet. There will be no more books because we will be able to get all texts from computers. People will use the Internet to play games, see films and buy food. Also,we can use the Internet to make telephone calls.

Some people are glad about these new ways of shopping and communication (交际). 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 using computers. We’ll 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 to lots of pages and we will save lots of paper. We will use more and more computerized (计算机化的) books

Is Internet shopping such a pleasure(愉快的事) 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 (不大可能) that many people will want to read large texts on our computers, because paper books may be more friendly. Maybe computers won’t change these two habits .
