¡¡¡¡I was only nine years old when I learnt how to use a computer.My mother is my first teacher.I know how to type,how to copy a file,and how to visit a web site on the internet.One day,mom was not at home.

¡¡¡¡I turned on the computer and began to learn how to chat on net.The first one I met there was a boy called tom. He greeted me politely.When he knew that I was only a 9-year-old girl,and almost knew nothing about chatting on net,he started showing me how to use the chatting tools,how to download,and how to send e-mails.I learnt a lot from him.
