根据以下资料，回答下面试题：
　　Experts say over half of the world’s seven thousand languages are in danger of disappearing.Every two weeks one language disappears.
　　Sometimes a language disappears immediately when the last person speaking it dies.Or, a local language might disappear more slowly.This happens when an official language is used more often and children stop learning the local language of their parents.Official languages often represent a form of control over a group of people.
　　Throughout history, the language spoken by a powerful group spreads across a civilization.The more powerful culture rarely respects the language and culture of smaller groups.Smaller cultures lose their local language as the language of the culture in power has a stronger influence.
　　Experts say protecting languages is very important for many reasons.Languages contain the histories, ideas and knowledge of a culture.Languages also contain valuable information about local medicines, plants and animals.
　　Many endangered languages are spoken by native cultures in close contact with the natural world.Their ancient languages contain a great deal of information about environmental systems and species of plants and animals that are unknown to scientists.As the last speakers of a language die off, the valuable information carried within a language also disappears.Language is, in many ways, a window to the mind and the world.
　　Any hope for protecting languages can be found in children and their willingness to learn.It is these young people who can keep this form of culture alive for future generations.

　　There’s a professor at the University of Toronto in Canada who has come up with a term to describe the way a lot of us North Americans interact these years.And now a big research study confirms it.
　　Barry Wellman’s term is “networked individualism.” It’s not the easiest concept to grasp.In fact, the words seem to contradict each other.How can we be individualistic and networked at the same time? You need other people for networks.
　　Here’s what he means.Until the Internet and e-mail came along, our social networks involved flesh-and-blood relatives, friends, neighbors, and colleagues at work.Some of the interaction was by phone, but it was still voice to voice, person to person, in real time.
　　But the latest study by the Pew Internet and American Life Project confirms that for a lot of people, electronic interaction through the computer has replaced a great deal of social interchange.A lot of folks Pew talked with say that’s a good thing, because of concerns that the Internet was turning us into hermits(隐居者) who shut out other people in favor of a make-believe world on computer screens.
　　To the contrary, the Pew study discovered.The Internet has put us in touch with many MORE real people than we’d have ever imagined.Helpful people, too.We’re turning to an ever-growing list of cyber friends for advice on careers, medical crises, child-rearing, and choosing a school or college.About 60 million Americans told Pew that the Internet plays an important or crucial role in helping them deal with major life decisions.
　　So we networked individuals are pretty tricky: we’re keeping more to ourselves, while at the same time reaching out to more people, all with just the click of a computer mouse!

　　A.Latin America B.Canada C.the United States D.Europe
