Julia , what do you think of the network ?   Network is omnipresent nowadays . It's quite convenient for people . You see , we can download music and information from the Internet ; I can study from it , too . And the most of all , we can compose , send , and receive e-mails .   Yeah , you are right . Internet makes our lives easier . But it's a two-blade sword .   What do you mean ?   I mean Internet brings benefit a lot , but also some disadvantages . For example , many youngsters are addicted to the games and they neglect their study ; or some bad guys steal people's money online , etc .
