When my father bought me a computer as a birthday gift for me in last year, I felt very excited. As we all know, computers are getting more and more usefully now. Much information can be stored in them. We can also learn that has lately happened in the world on the internet. In past, people had to do lots of work which was very dangerous. Now, but, computers can do it instead. When an exam is coming, I often did some exercises on my computer. Then it will correct it and tell me the right answers. In this way it is very convenient for me to prepare the exam than before. The computer has become my real friend.
