My Net Friend_450字_作文大全网

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.
