　　Build the highway and watch the town grow.At first a few shops appear and maybe a restaurant.Then a hotel opens. Eventually new house 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 travelers come bringing new kinds of information.New villages are started.

　　Every willage has a founder.Tim Berners-Lee is the man who wrote the software programme that led to the foundation of the Word 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 in formation from different sources. The dream behind the Web is of a common space in which we communicate by sharing information."

　　In 1991 his programmmes were placed on to the Internet.Everyone was welcome to use them.

　　Tim Berners-Lee could have followed the Microsoft route by forming a company to sell the programmes he invented. Or he could have joined another company. But in his view the Web is a language,not a pproduct. Charging a gee for using his programmes 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 (不相容的) software. They 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 world of English.

　　In 1994 Tim Berners-Lee formed the 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 solftware,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.

America is growing older. Fifty - eight years ago, only 4 out of every 100 people in the United States were 65 or older. To day, 10 out of every 100 Americans are over 65. The aging of the population will affect（影响）American society in many ways—education, medicine, and business. Quietly, the graying of America has made us a very different society—one in which people have a quite different idea of what kind of behavior（行为） is suitable（合适）at various , ages.

　　A person s age no longer tells you anything about his/her social position, marriage or health. There’s no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn’t as strong as it used to be. It doesn’t surprise us to hear of a 29 - year - old university president or a 35 - year -old grandmother, or a 70 year - old man who has become a father for the first time. Public ideas are changing.

　　Many people say, “I am much younger than my mother— or my father— was at my age. ”No one says“Act your age” any more. We’ve stopped looking with surprise at older people who act in youthful ways.

1.It can be learnt from the text that the aging of the population in America ________ .

2.The underlined word “one” refers to ________ .

3.“Act your age” means people should ________ .

4.If a 25 - year - old man becomes general manager of a big firm, the writer of the text would most probably consider it ________ .

—Shall we go out for a walk?

—Sorry. This is not the right _______ to invite me. I am too tired.

　 A. place　　　　　　　　　　　　 B. situation　　　　　　　　　 C. chance　　　　　　　　 D. moment

Researchers who helped discover a new species of Mexican butterfly are offering to sell the naming rights to raise money to fund more research. Co-discoverer Andrew Warren is hoping to raise at least $50,000 by auctioning(拍卖) off the rights to name the 4-inch “owl eye” butterfly, which lives in Sonora, a Mexican state bordering Arizona.

“That would support at least two years of research for our team down in Mexico,” Warren said. “Money goes a long way down here in Mexico.”

According to the scientific tradition, discoverers of a new species have the say in naming it. In recent years, some discoverers have auctioned off their naming rights to raise money.

Warren said the amount being sought for the butterfly is not out of the question, noting that naming rights for a new monkey species brought in $650,000 two years ago. A group of 10 new fish species that went on the naming auction block at the same time earlier this year brought in a total of $2 million.

The butterfly discovered by Warren and researcher George Austin ranges as far north as Mexico.

The butterfly was actually in a collection, misidentified as an example of another new species, at the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of National History in Gainesville, said Warren. They soon began the hard process of determining that it was indeed a “new” model of butterfly.

After checking photos and comparing it with other known species, they determined it was a separate species.

Where did the researchers discover the new species of butterflies?

   A. In Sonora.                        B. In Mexico state.       

   C. In a place in US.                D. Near the US-Mexico border.

Why will the researchers sell the naming rights of the butterfly?

To raise money for wildlife protection.

To raise money for more research.

To cause people’s attention to the new discovery.

To cover the cost of the research.

When the butterfly was first discovered, people thought ______.

it was a new species at once

it wasn’t a species of American butterfly

it belonged to the monarch branches

it belonged to a new species

We can infer from the passage that ______.

the new species of butterfly live both in the US and Mexico

it took the researchers a lot of efforts to determine the new species of butterfly

the researchers are not sure whether they can get the money they want from the auction

it is the first time that the new species of butterfly has been found
