阅读理解。

     Endangered languages are languages that wouldn't exist any longer, much like endangered species of

plants or animals. Languages are considered to be endangered when parents are no longer teaching the l

anguage to their children and are not using it actively in everyday life. A language is considered to nearly

disappear when it is spoken by only a few elderly native speakers.

     The world faces enormous challenges in order to protect different kinds of languages. Of the more than 6,912 languages, half may be in danger of disappearing in the next several decades.

     It is caused by many reasons: small numbers of speakers, the regular use of other languages, attitudes

towards their languages, moving of the younger population, government policies, and languages used in

education and so on. A language may lack important things such as a body of literature, and people who

read and write it. A language may also lack prestige (声望) and support of its speakers.

     The survival of a language is also threatened when speakers move to other areas where different

languages are spoken, or when government policies improve the use of a specific language in school,

official business and the media. These situations encourage people to learn the wider-known language

and may cause them, especially the young, to stop using their mother tongue. Often those speaking

lesser-known languages will choose to learn a more prestigious language with the hope of greater

economic opportunities. Most of the world's parents are teaching their children English, French, Spanish,

Chinese, Arabic, Russian or some other main languages instead of their own languages for social and

economic reasons.
