Of the 7,000 languages spoken in the world today, linguists (语言学家) say, nearly half are likely to disappear this century. In fact, one falls out of use about every two weeks.
Some languages die out in an instant, at the death of the only surviving speaker. Others are lost gradually in bilingual (双语的) cultures, as local tongues are edged out by the dominant (占主导地位的) language at school, in the marketplace and on television.
New research, supported by the National Geographic Society and the Living Tongues Institute for Endangered Languages, has found the five regions where languages are disappearing most rapidly. They are northern Australia, central South America, North America's upper Pacific coastal zone, eastern Siberia, and Oklahoma and the southwestern United States.
K. David Harrison, an associate professor of linguistics at Swarthmore College, US, said that more than half the languages had no written form and were vulnerable to loss and being forgotten." Their loss leaves no dictionary, no text, or no record of the accumulated knowledge and history of a disappeared culture.
Harrison and other researchers started their rescue project last year. They have been trying to identify and record endangered languages. They interviewed and made recordings of the few remaining speakers of a language and collected basic word lists. The individual projects, some lasting three to four years, involve hundreds of hours of recording speech, developing grammar and preparing children's readers in the obscure (逐渐没落的) language. The research has concentrated on preserving entire language families.
"These are probably languages that cannot be brought back, but at least we made records of them," said Gregory Anderson, director of the Living Tongues Institute, in Oregon, US.
