With the develop of modern technology，computer is widely used in my life。With the help of computer I can learn of anything in the world。 With computer"s help I can work easily，so I have more free time than before，and I can talk with my friends online。I don"t need to buy books，because I can read books online。I can buy things online。
So since I have the computer I only need to sit in my room and I can know anything on the earth。
