Nội dung đoạn văn: "Response # 1Re: The Internet Posted by Sandra Morgan In my opinion, the Internet is a very fast and convenient way for me to get information. I can also communicate with my friends and relatives by means of email or chatting. However, I don't use the Internet very often because I don’t have much time. For me, the Internet is a wonderful invention of modem life. It makes our world a small village. Response # 2 Re: The Internet Posted by Honghoa Nobody can deny the benefits of the Internet in our life. However, it is a pity for me as well as for most of my friends in the countryside. The Internet is available only in cities, therefore I cannot easily get access to it. I sometimes visit my uncle in the city on weekends, and this is a good occasion for me to explore the net. I spend most of the time wandering because I just don’t know which website is useful for me. Response # 3 Re: The Internet Posted by Huansui People use the Internet for many purposes: education, communication, entertainment and commerce. However, the Internet has limitations. It is not only time-consuming and costly but also dangerous because of viruses and bad programs. Moreover, Internet users sometimes have to suffer various risks such as spam or electronic junk mail, and personal information leaking. So, while enjoying surfing, be alert!"
