Our only link to the real world has been a computer that is hooked up to the Internet (联网电脑). We have relied on it, not only for food, bed sheets and other daily necessities, but also to set up an e-business （电子商务）of our own.2) Now Ss will complete the next paragraph beginning with: “Now it is time for me to walk out into the light of day again.” They will give their imagination full play. They will write no more than 100 words.3) Ss form groups of four to five, and read aloud to each other their own writings.4) T asks some groups to recommend the best piece in their group to the class.4. T may lead in to Text A by saying: Some of us like to live a life in contact with real things and real people, but others favor a virtual existence. Which life is better? Im sure you have different opinions. Now lets read Text A to find out what Maia Szalavitz has to say about these two life styles.

(They are: virtual life, the net, telecommuter, email, Internet mailing lists, computer-assisted, data, link, cyber-interaction, on line, system crash, click on the modem, connection, password)2) T tells Ss that new terms related to computer and the Internet are constantly added to the English vocabulary, so much so that many of them are not included in any English dictionary. However, if we apply certain rules, their meanings are easy to deduce.3) T gives Ss more examples of computer-related vocabulary items (see Text Analysis).2.

Cultural Notes1. the Internet: an international computer network for the exchange of information. It was originally used mainly in the academic and military worlds but has since become available to the large and increasing number of people with personal computers. Other services, e.g. the World Wide Web, are available through it.The Internet is changing our lives and a parallel universe is rapidly emerging online. Today theres scarcely an aspect of our life that isnt being upended by the torrent of information available on the hundreds of millions of sites crowding the Internet, not to mention its ability to keep us in constant touch with each other via electronic mail. The Internet is saving companies billions of dollars in producing goods and serving the needs of their customers. Nothing like it has been seen since the beginning of the Industrial Revolution, when power-driven machines began producing more in a day than men could turn out in nearly a year. The Internet and e-commerce are viewed as a global megatrend along the lines of the printing press, the telephone, the computer and the electricity.You would be hard pressed to name something that isnt available on the Internet. Consider: books, health care, movie tickets, baby clothes, stocks, real estate, toys and airline tickets. American kids today are so computer savvy that it virtually ensures the United States will remain the unchallenged leader in cyberspace for the foreseeable future. Most kids use computers to play games and have email chats with friends.Whats clear is that, whether we like it or not, the Internet is an ever-growing part of our lives and there is no turning back.2.
