consumer products become similar. Already English and a few other major tongues have emerged as global languages of commerce and communication. For many of the world’s peoples, learning one of these languages is viewed as the key to education, economic opportunity, and a better way of life.
Only about 3,000 languages now in use are expected to survive the coming century. Are most of the rest doomed in the century after that?
Whether most of these languages survive will probably depend on how strongly cultural groups wish to keep their identity alive through a native language. To do so will require an emphasis on bilingualism（mastery of two languages）. Bilingual speakers could use their own language in smaller spheres---at home, among friends, in community settings---and a global language at work, in dealings with government, and in commercial spheres. In this way, many small languages could sustain their cultural and linguistic integrity alongside global languages, rather than yield to the homogenizing（同化的）forces of globalization.
Ironically, the trend of technological innovation that has threatened minority languages could also help save them. For example, some experts predict that computer software translation tools will one day permit minority language speakers to browse the Internet using their native tongues. Linguists are currently using computer—aided learning tools to teach a variety of threatened languages.
For many endangered languages, the line between revival and death is extremely thin. Language is remarkably resilient（有活力的）,however. It is not just a tool for communicating, but also a powerful way of separating different groups, or of demonstrating group identity. Many indigenous（原生的,土著的）communities have show
