Teaching ObjectivesStudents will be able to:1. understand the main idea(despite the many negative effects of virtual life, the author prefers it to real life) and structure of the text (contrast between virtual life and real life);2. learn some rules of interpreting new vocabulary and usage related to computers and the Internet in English;3. grasp the key language points and grammatical structures in the text;4. conduct a series of reading, listening, speaking and writing activities related to the theme of the unit.II. Key Points: The structure, the writing skill, and the main idea of the text will be the focus. Only a few words and sentences, which will be the obstacles for students understanding of the text, will be explained in class.III. Difficult Points:Some sentences whose meanings are difficult to understand and whose structures are hard to analyze:1. Line 26-28（Para. 6）: I find myself shyer, more cautious. Or, conversely, when suddenly confronted with real life humans, I get overexcited, speak too much, interrupt.2. Line 45-47(Para.9): When I am in this state, I fight my boyfriend as well, misinterpreting his intentions because of the lack of emotional cues given by our typed dialogue.IV.

Imaginative writing (28 minutes)1) T dictates to Ss the following paragraph: For the past two weeks, other participants of the Net Survival Contest(网络生存竞赛) and I have been shut up in bare hotel rooms. 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 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?

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 there is 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 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, whatever we like it or not, the Internet is an ever-growing part of our lives and there is no turning back.2.
