Passage A: Virtual Community
Virtual communities give people an opportunity to fulfill their dreams. A timid man in real life turned into a hero for various
brave deeds he performed to help people in Virtual Reality.
Now there're some websites where you can sign up and live in a virtual world. You'll get a small apartment and a little money. You choose a street you want to live on and a profession to make yourself earn some money. Game rules are similar to those of the real world—the more money you have, the more powerful you are. Choose a street to stroll on and you are likely to meet many neighboring citizens who are usually friendly. If you're cheated or hurt, or mistreated by someone, you can go to the city affairs office to sue him or her. And if found guilty, he or she will be sent to a virtual prison, where he or she will be deprived of rights as a citizen: no work, no game, no public speech and required to meditate over his or her mistake. Gambling is no longer a serious sin since it is virtual money you win or lose.
Passage B: Come And Try Blogging
The blog is one form of communication that increased
in popularity. Blog is a short way of saying Web log. Through these personal Web sites, people can share their lives, ideas and opinions with anyone on the Internet. Millions of people throughout the world are creating and reading blogs. There are reportedly thirteen million blogs in the United States alone.
People of all ages have their own blogs. For young people, they are a way to show their writings and other forms of self-expression. Blogs also connect people with other people who have the same interests. For example, teachers use blogs to share ideas, experience and concerns about their work with other teachers.
Many Web sites offer free services to create personal Web pages and fill them with writings and pictures. These sites include "MySpace", used mainly by teenagers and young adults. MySpace is an online community that lets people share messages and pictures with an increasing number of friends. About one hundred twenty million people use MySpace. It is the most popular social networking site on the Web.
Passage C: Person of the Year: It’s YOU!
At the end of every year, the US magazine Time chooses the person who has the biggest influence on the world, whether for
better or for worse. Usually famous people are chosen. For example,
you can find late Chinese leader Deng Xiaoping and German-born scientist Albert Einstein there.
But for 2006, Time chose "You" as "the Person of the Year" because almost everyone in the world is using the Internet now. They are changing the world by using blogs,
YouTube and Wikipedia.
In China, according to a report this July, 28 million people read or write blogs. Many of them are students.
Some also put videos online. The most famous video website is YouTube. People can put whatever they shoot with a video camera or mobile phone on this site. Every day, 100 million people visit YouTube. "Once only journalists had the power to tell you the news. But now a student in Baghdad with a video can let you see a bombing," said Rick Stengel, an editor of Time magazine. He said that the Internet makes ordinary people have the power to report news to the world.
The Web also helps people to work together for greater achievements. Wikipedia, the Web encyclopedia, is the most successful example. Anyone can write and edit stories for it over the Internet. With the efforts of millions of people, Wikipedia is now the biggest encyclopedia in the world.
Passage D: Cutting A Frog On the Net
Many people remember the day in school when they had
to cut up a dead frog. Students often perform this
dissection as a requirement for biology class. Smelly
formaldehyde preserves the body of the frog. The students remove and identify the organs as part of learning about the science of life.
But some schools no longer require students to cut apart frogs. Cost may be an issue. Also, animal rights activists may object.
Today, more and more students learn about frogs by computer, through "virtual dissection." A company called Froguts () sells educational services to schools. But it also offers a free demonstration on its Web site. First, the image of a whole bullfrog appears on the screen. Users of the site direct cutting tools with clicks of their computer mouse. Lines show where to cut. Several steps later, the frog is open. The next steps are to remove and identify the heart, lungs and other organs.
Some educators praise virtual dissection. Others say nothing can replace the real thing.
Other virtual activities are also increasingly popular in schools. Some schools cannot send their students to places like museums and zoos. Distance and money may prevent them. But children can still "visit" zoo animals, museum collections and historic places by computer.
Last year, Maine launched a plan to become the first state to provide laptop computers to each of its middle school students and teachers. Maine is a small Northeastern state which, like many other states, is facing budget troubles. But now seventh and eighth graders and their teachers in more than 240 schools have these wireless computers.
And the idea is spreading. Michigan, for example, has started to spend $22,000,000 for laptop or hand-held computers for sixth graders. Schools can get the computers if they can pay 25 dollars for each student.
Yet such plans have critics, as a story in the magazine U.S. News and World Report noted. They say there is little proof that computers are better than traditional teaching methods. Other teachers say the computer is simply another tool that depends on how it is used.
Passage E: Virtual World
Build the highway and watch the town grow. At
first a few shops appear and maybe a restaurant. Then
a hotel opens. Eventually new houses are built. A
village is born.
This is also how the virtual world has developed. Think of the Internet as the road carrying information between two computers. Think of the World Wide Web as the village. At first it is just a place on the virtual road where travelers meet. More travelers come bringing new kinds of information. New villages are started.
Every village has a founder. Tim Burners-Lee is the man who wrote the software program that led to the foundation of the World Wide Web. How did he get the idea?
He tells us on his own web site. "One of the things computers were not able to do was store contacts from different sources. The dream behind the Web is of a common space in which we communicate by sharing information.
Tim Berners-Lee could have followed the Microsoft route by forming a company to sell the programs he invented. Or he could have joined an existing company. But in his view the Web is a language, not a product. Charging a fee for using his programs would have slowed the growth of the Web. And other companies would make similar products to compete. Instead of one World Wide Web there would be several smaller Webs. Each would use incompatible software. The Web is valuable because it uses a common computer language to reach people and share information. Competing webs would lose this value. Imagine if somebody sent you a bill every time you spoke a word of English.
In 1994 Tim Berners-Lee formed the newly formed World Wide Web Consortium, or W3C. More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone, no matter what their equipment or software, can work equally on the Web.
"The Web can help people to understand the way that others live and love. It helps us understand the humanity of people." He says.。
