Computers are very important to modern life. Many people think that in the future computers will be used a lot in everyday’s 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 fewer books because we will be able to get all texts from computers. The Internet will be used to play games, see 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(交际). Others do not think that computers will replace(代替) our old ways.
   Let’s take books for example. Some people think that one day we won’t 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. Computerized books will be used more and more.
   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. It is also unlikely(不大可能) that many people will want to read large texts on our computers. Because paper books will perhaps be more friendly. Maybe computers won’t change these two habits(习惯).

     All students need to have good study habits. When you have good study habits, you will learn things quickly and also remember them easily. Do you like to study in the living room? This is not a good place, because it is usually too noisy. You need to study in a quiet place, like your bedroom A quiet place will help you only to think about one thing. When you study, do not think about other things at the same time. Only think about your homework. If you do so, you will do your homework more quickly, and you will make fewer mistakes.
    Good study habits are very important. If you do not have them, try to learn them. If your studyhabitsare already good. Try to make them better.
