    ) called a telegraph key.

    2. On Aug. 5th, 1858, the first message was transmitted (传播) by a wire cable under

    Part II Net changes dorm life

    Listening Tasks:

    A. Listen to a report about the Internet. Focus on the areas and examples that that the Internet will bring change in. Supply the missing information.

    Academics b. getting assignments and research papers

    c. attending professors “virtual office hours”

    d. posting course lectures

    Entertainment b. online games

    Communications b. Toll-free phone calls

    Commerce e-commerce orders

Tapescript:

    The proposed merger of America Online and Time Warner anticipates an age when high-speed Internet access is everything. It will be a pipeline for almost all the entertainment, communications and information that people consume.

    It is an era so distant to most Americans that they can hardly envision it. And yet it already exists. In fact, it is the only world that today’s college students know.

    Colleges across the United States have spent hundreds of millions of dollars in recent years wiring dormitories for high-speed Internet access.

    When admissions people go out and talk to students these days, the students always ask, “Do you have a high-speed network?” Indeed, for today’s students, having

    high-speed Internet access is a top priority. They base their housing decisions on it, and restructure their meager student budgets to afford it.

    College administrators acknowledge that academic pursuits are just a fraction of the activity on their campus networks. The bulk of the traffic consists of data containing music files, instant messages, toll-free phone calls, e-commerce orders, online games and just about anything.

    At a high-rise dorm at the University of Southern California, walking down the hallway on the eighth floor almost any time of day, you’re likely to hear students in separate rooms shouting at each other –‘‘You killed me!”-- as they mow each other down

    in online games played over the network. Friends from opposite ends of the floor simultaneously make for the elevators. They've just messaged each other by computer

    that it’s time to head off to the dining commons. To them, knocking on someone’s door is an antiquated 20th century tradition.

    Today’s students register for classes, get their homework assignments, research papers and attend professors’ “virtual office hours” online. Some universities even post course lectures on the Net, so that students can review them any time they wish.

    Just as one of the students put it: “We live our lives over the Internet.”

    1F; 2F; 3T; 4T; 5F.

    Tapescript:

    On Monday, the largest provider of Internet service in the world announced plans to buy the world’s largest media company. America Online and Time Warner expect to combine their businesses by the end of the year. The new company will have a major influence in many areas including music, publishing, news gathering, films and the Internet. The new company will be called AOL Time Warner.

    America Online agreed to buy Time Warner with stock. Some media estimates said the agreement was worth as much as 180 thousand million dollars. However, share prices in both companies fell as the week continued. The agreement shows that traditional media no longer exist separately from the media created by new technology. Time Warner admits that its efforts to move in new directions have not always succeeded. So it welcomed the offer by America Online. The agreement surprised many people. Time Warner earns a lot more money than America Online. However, America Online is growing faster.

    Many investors consider the stocks of Internet companies to be more valuable than those of traditional companies. The value of America Online stock has risen 800% in the past two years. The sale of Time Warner to America Online must be approved by shareholders in both companies. It also will be closely examined by federal officials. Some experts say AOL Time Warner could be as powerful as the computer software company Microsoft. Other Internet and media businesses may feel more pressure to unite. The agreement comes as traditional media companies try to decide how best to use the power of the Internet. At the same time Internet companies want to reach more people. Media observers worry that as the Internet becomes more popular it will become controlled by fewer and fewer companies. That’s why some groups oppose the sale of Time Warner to America Online. They want the government to make sure that the Internet does not become just another place of business.
