B:
One feature of the information superhigha is that the traffic travles fast, and techies use their own special shorthand to keep mesages zooming along. Today we’l help you decode tach talk by answering soome not so frequently asked questions about abbreviations on the Internet.
What does it mean when a message includes the letters AISI or IMHO? AISI stands for “as I see it” and IMHO is shorthand for “in my humble opinion”.
Some modest folks will also add FWIW before sharing their opinion, which stand for “for what it’s worth”. Others express their disapproval with the letters CMIIW. That is “correct me if I’m wrong”
The lsit of commonly abbreviated phrases on teh Net is neaerly endless. As a matter of fact, AAMOF stands for “as a matter of fact” and “believe it or not” gets posted as BION.
Are there any pre-Information-Age abbreviations still making tteh rounds in this high-tech era? You bet. The old stadnbys FYI, MYOB, and SOP which stand for “for your information”, “ mind your own business,” and “standard operating procedure” are still frequently used today even in email.
Since time is getting short, ahs the Net given us truly short and clear ways to say good-bye? Try TAFN (That’s all for now) and BCNU (be seein’ you).

6. right now the world is focused on e-commerce.
7. The invention for the web brings rapid rewards to people wit imagination and new ideas.

Part II
A1
Connected / system / connection / work together / stations / people
A2
Connection of railroads or other vehicles
Connected system of radio stations
System linking a number of computers together.

原文：
Few things in this world change as fast as languages. Every day, new words are created to deal with new ideas or new technologies. New meanging also are added to exisitng words. A dictionary published years ago may show one or two meanign for a word; a dictionary published today may list several more meaning for the same word.
Network is one such word. It combines two words. The first is “net”, it means materials that are connected; the second is “work”. One meaning of “work” is a system. Network means a connection of systems that work together. The systems that networks connect can be very different. For example ,radio and television stations can be connected in the network, so can computers and even people.
Word expert Milford Matthew found written uses of the word “network” in the late 1980s. The word then was used as a verb, a word that show action. At that time network meant the connection of railroads or other vehicles used for travel. One publication said it is only a question of time when the railroads will network an area of the American west called the “Pan Handle”. Another publication of the time said complete areas are networked by trolley cars , which are a kind of electric train.
Now we often hear network used in connections with broadcasting. The Barnhart Dictionary of New English says that as early as 1914, people used it to mean a connected system of radio stations. This meaning continues to be popular. A more modern use of the word “network” is linked to computers. A network is a system that links a number of computers together. Networks make it possible for people who use computers to share information in costly equipment. Many companies and government agencies share the same computer network. The computers are linked through a main computer or through special lines. Some people are able to do their jobs from their home computers.
Computers networks also permit an exchange of unofficial information and discussion between computer users. By linking their computers to telephones, people can buy goods through their computers. They can send messages to friends in many countries.
Another modern use of the word “network” concerns relations between people. Ideas and information are exchanged by people who network to share interests and goals. Many Americans network to get better jobs or to meet new friends. Meeting new friends by networking is not work though is fun.

B
B1
b. Getting assignments and research papers
c. Attending professors’ “virtual office hours”
d. Course lectures.

Entertainment b. online games

Communications b. toll-free phone calls

e-commerce orders.

原文:
The proposed merger of America Online and Time Warner anticipates an age when high-speed Internet access is everything. It will be 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 envious it. And yet is already exists. In fact, it is the only world that today’s college students know. Colleges across the United Sates 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 asks, “Do you have a high-speed network?” indeed, fro 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 phones calls, e-commerce orders, online games and just about anything.
Ata a high-rise dorm at the University of Southern California, walking down the hallway on the eighth floor almost any time of dya, 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 the students put it “We live our lives over the Internet.”
