Listening InTask 1: The Internet on CampusThe Internet, a worldwide information network, is used at universities mainly as an information supply source. Staff supply information via the Internet and students may access it or any other publicly available information. The Internet is also useful for students to communicate with staff. Teachers may present lecture materials in lecture halls, and at the same time, they can distribute the materials for students to access from any location at any time via their computer. Such materials are preesented mainly in the form of text, still pictures and hypertext links. Students find this valuable and relevant to their needs. If they must miss a lecture, students can still keep up to date. Staff users may put up notices of conferences, maintain professional contacts, and communicate and conduct discussions with their colleagues or students. Students, on the other hand, are taught haow to use the Internet as an individual productivity tool in several courses.l.A 2.D3. A 4. A 5.CTask 2: Surfing the NetW: Hi Bryan. Hare you doing? You look tired.M： Oh, I'm a little burnt out. I've been surfing the Net for the last few hours.W: Were you doing schoolwork, or was it just for pleasure?M： Well, I wanted to get some information on South America for a project I have, but I found a really interesting chat site with people from there and started chatting.W: Well, did you get the information you needed?M： Yes, but then we spent lots of time chatting about other interests.W: I see. The Internet is a wonderful place. There is so much information available. I completely understand how you can get distracted. Sometimes I find myself looking for one piece of information, but by the time I am finished I have a lot more than I started off looking for.M： I know. One thing I really don't like about it, though, is it takes so much longer to find things, because many sites are useless.W: Yes, there's that, and also, I often find the same site over and over again in a search. That definitely wastes lots of my time.M： And, of course, there are sites that offer little to no relevant information on the topic you are searching for. In my search today, I found quite a few sites that were nothing more than old local news archives and event calendars.W: Well, I'm sure they were useful to someone at some time, but they should be removed when they're no longer of use to anyone.M： I agree. With all the time I spnd on it, I still find it to be the best source of information available. And speaking of information, I really should read through what I got on the Internet and start working on my project.W: Okay. Good luck. It's funny we had this chat, as I was just on my way home to surf the Net myself.M： Well, it was nice talking to you, and maybe I'll meet you in a chat room later tonight.1.

College students have lots free time to spend and many of them are supplied with free Internet access and a computer in their doorms. It's really easy to get addicted.

Furthering Listening and SpeakingListeningTask 1: The Origin of the InternetThe story of the Internet begins in the late 1950s. The Soviet Union launched Sputnik in 1957. The Pentagon set up a research team in 1958 to create a computer network to operate during disasters like a nuclear war. The resulting network linked U.S. scientific and academic researchers. It grew into the World Wide Web or the Internet that became the network system of the Information Age.In1985, the National Science Foundation created a network which provided a free national service to any U.S. research and education institution. Later, large corporations began to build their own networks. All those networks finally joined the Pentagon's network to form the Internet. By the 1990s, anyone with a computer, a modern, and Internet software could link up to the Internet. In thefuture, the Internet will probably grow more complex and become part of a larger network called theinformation highway. With that people could bank, shop, watch TV, and perform many otheractivities online.1 .the late 1950s disasters2 .the World Wide Web the World Wide Web3 .a free national service research and education institution4 .The 1990s Internet software link up5 .a larger network the information highway onlineTask2: The InternetA Small TownThe Internet is a global network, but in many ways it's like a small town with similar services to offer. There are electronic post offices to send and receive e-mail, functioning somewhat more efficiently than the Post Office we know. There are libraries of information that stay open 24 hours a day with millions of books and documents to browse or search through on the World Wide Web or WWW. You can also enjoy real-time text-based communication, using written or printed material to communicate with others immediately and almost t4face to face". Local coffee shops are seen in the guise of chat room, with people dropping by at all hours of the day and night to socialize. Online education and training is available just as it is in a "bricks and mortar" university or school. Online banking offers you all the services available at your local bank, without fearing to be mugged at an ATM. You can buy almost anything, listen to your local radio station or do your grocery shopping. Indeed, the Internet is your town in a box!Task3: If only life could be like a computer!To get your daily exercise, just click on "run"!If you need a break from life, click on "suspend".Hit "any key" to continue life when ready.To “add/remove" someone in your life, click settings.To improve your appearance, just adjust the display settings.When you lose your car keys, click on "find".You could click on "send" and the kids would go to bed immediately.To feel like a person, click on "refresh".Click on "close" to shut up the noises.To undo a mistake, click on "back".Is your furniture getting old?
