In the last ten years, the Internet has opened up incredible amounts of information to ord

inary citizens. But using the Internet can be like walking into a library where the books are all lying on the floor in piles. While tools like Google allow some structured search, much of the data from such searches is outdated or of questionable value. Some web enthusiasts have taken up the task of organizing information through a democratic means that only the Internet allows: an encyclopedia of the people, by the people, and completely free to copy and distribute.

This people's encyclopedia' of the Web (a free site called Wikipedia) has provided a unique solution by inviting individuals to participate in the process of rationalizing and updating web con- tent. At the heart of this movement are wikis, web sites that allow users to directly edit any web page with one click of the mouse.

Wikipedia (the largest example of these collaborative efforts) is a functioning, user-contributed online encyclopedia that has become a popular and highly regarded reference in just three years of existence. The goal of Wikipedia was to create an encyclopedia that could be shared and copied freely while encouraging people to change and improve the content. Each and every article has an "Edit this page" button, allowing anyone, even anonymous passersby, to add or delete any content on the page. It seems like a recipe for disaster and chaos, but it has produced surprisingly credible content that has been evaluated and revised by the thousands of international visitors to the site.

The Wikipedia project was started by Jimmy Wales, head of Internet startup bomis com, after his original project for a volunteer, but strictly controlled, free encyclopedia ran out of money and resources after two years. Editors with PhD degrees were at the helm of the project then, but it produced only a few hundred articles. Not wanting the content to languish, Wales placed the pages on a wiki website in January 2001 and invited any Internet visitors to edit or add to the collection.

The site became a runaway success in the first year and gained a loyal following, generating over 20,000 articles and spawning over a dozen language translations. After two years, it had 100, 000 articles. Over 2,000 new articles are added each day across all the various languages. And ac- cording to website rankings at alexa, com, it has become more popular than traditional online encyclopedias such as britannica, com and is one of the top 200 most heavily visited websites on the internet.

The author called Wikipedia people's encyclopedia because it______.

A．is accessible by all the passersby.

B．can be edited by everyone.

C．is run by ordinary people.

D．is built to the taste of common citizens.

听力原文： You can tell the age of a tree by counting its rings, but these records of trees
’ life really say a lot more. Scientists are using tree tings to learn what's being happening on the sun's surface for the last ten thousand years. Each ring represents a year of growth. As the tree grows, it adds a layer to its trunk taking up chemical elements from the air. By looking up the elements in the rings for a given year, scientists can tell what elements were in the air that year. Doctors Stevenson is analyzing one element—carbon-14 in ring from both living and dead trees. Some of the tings go back almost ten thousand years to the end of the Ice Age. When Stevenson followed the carben-14 trail back in time, he found carbon-4 levels change with the intensity of solar burning. You see, the sun has cycles. Sometimes it burns fiercely and other times it's relatively calm. During the sun's violent periods, it throws off charged particles in fast moving strings called solar winds. The particles interfere with the formation of carben-14 on earth. When there's more solar wind activity, less carbon-14 is produced. Ten thousand years of tree rings show that the carbon-14 level rises and falls about every 420 years. The scientists concluded that the solar wind activity must follow the same cycle.

What can the tree's rings tell us？

A．The age of the tree.

B．The changing activities of sun.

C．A lot more.

D．All the above.

Dr. Stevenson is analyzing one element, carbon—14, in rings from both living and dead trees. Some of the rings go back almost ten thousand years to the end of the Ice Age. When Stevenson followed the carbon--14 trail back in time, he found carbon—14 levels change with the intensity of solar burning. You see the sun has cycles. Sometimes it bums fiercely. At other times it's relatively calm. During the sun's violent periods, it throws off charged particles in fast moving streams, called solar winds. The particles interfere with the formation of carbon—14 on earth. When there is more solar wind activity, less carbon—14 is produced. Ten thousand years of tree rings show the carbon—14 level rises and falls about every four hundred and twenty years. The scientists concluded that solar wind activity must follow the same cycle.

A．To find out the origin of carbon- 14 on Earth.

B．To analyze the composition of different trees.

C．To look into the pattern of solar wind activity.

D．To examine the chemical elements in the Ice Age.

Iris Rossner has seen eastern German customers weep for joy when they drive away in shiny,
new Mercedes—Benz sedans. "They have tears in their eyes and keep saying how lucky they are," says Rossner, the Mercedes employee responsible for post-delivery celebrations. Rossner has also seen the French pop corks on bottles of champagne as their national flag was hoisted above a purchase and she has seen American business executives, Japanese tourists and Russian politicians travel thousands of miles to a Mercedes plant in southwestern Germany when a classic sedan with the trademark three-pointed star was about to roll off the assembly line and into their lives. Those were the good old days at Mercedes, an era that began during the economic miracle of the 1960s and ended in 1991. Times have changed. "Ten years ago, we had clear leadership in the market," says Mercedes spokesman Horst Krambeer, "But over this period, the market has changed drastically. We are now in a pitched battle. The Japanese are partly responsible, but Mercedes has had to learn the hard way that even German firms like BMW and Audi have made efforts to rise to our standards of technical proficiency."

Mercedes experienced one of its worst years ever in 1992. The auto maker's worldwide car sales fell by 5 percent from the previous year, to a low of 527,500. Before the decline, in 1988, the company could sell close to 600,000 cars per year. In Germany alone, there were 30,000 fewer new Mercedes registrations last year than in 1991. As a result, production has plunged by almost 50,000 cars to 529, 400 last year, a level well beneath the company's potential capacity of 650,000. Mercedes's competitors have been catching up in the U.S., the world's largest car market. In 1986, Mercedes sold 100,000 vehicles in America; by 1991, the number had declined to 39,000. Over the last two years, the struggling company has lost a slice of its U.S. market share to BMW, Toyota and Nissan. And BMW outsold Mercedes in America last year for the first time in its history. Meanwhile, just as Mercedes began making some headway in Japan, a notoriously difficult market, the Japanese economy fell on hard times and the company saw its sales decline by 13 percent in that country.

Revenues(收益) will hardly improve this year, and the time has come for getting down to business. At Mercedes, that means cutting payrolls, streamlining production and opening up to consumer needs. Revolutionary steps for a company that once considered itself beyond improvement.

The author's intention in citing various nationalities' interests in Mercedes is to illustrate Mercedes' ______.

A．sale strategies

B．market monopoly

C．superior quality

D．past record

听力原文：Identity theft is considered one of the top crimes in the United States. The Fede

听力原文： Identity theft is considered one of the top crimes in the United States. The Federal Trade Commission estimates that ten million Americans become victims of identity theft each year. (32) Identity thieves steal personal information. They collect Social Security numbers, banking records and telephone numbers. They use this information to request loans or get credit cards in the name of the victim. Identity thieves spend a lot on goods or services without paying for them. F.T.C. officials estimate more than fifty-two thousand million dollars in goods and services were purchased last year through identity theft. (33) Victims of identity theft can spend years attempting to re-establish their financial history and good name. Identity thieves use several methods to get what they need. They may trick people into giving personal information over the telephone. They also may steal documents containing such information. (34) Activist groups have called for new laws to protect the public from identity theft. Recently, a committee of the United States Senate said it would hold hearings on the issue. Two cases of identity theft helped the committee to call the hearings. Last month, Bank of America said it lost computer tapes containing personal information for more than one million federal employees. Earlier, the Los Angeles Times newspaper reported that thieves stole about one hundred fifty thousand personal records from Choice Point Incorporated. (35) American lawmakers will consider plans to increase monitor of companies that collect personal information. Several plans have been proposed to help individuals whose personal information was stolen.

(33)

A．Banking cards.

B．Personal belongings.

C．Personal information.

D．Valuable goods.
