The Day a Language Died
When Carios Westez died at the age of 76, a language died, too. Westez, more commonly known as Red Thunder Cloud, was the last speaker of the Native American language Catawba. Anyone who wants to hear the songs of the Catawba can contact the Smithsonian Institution in Washington, D.C., where, back in the 1940s, Red Thunder Cloud recorded a series of songs for future generations.________ (46) They are all that is left of the Catawba language. The language that people used to speak is gone forever.
We are all aware of the danger that modern industry can cause the world’s ecology(生态).However, few people are aware of the impact widely spoken languages have on other languages and ways of life. English has spread all over the world. Chinese, Spanish, Russian, and Hindi have become powerful languages as well. As these languages become more powerful, their use as tools of business and culture increases. As well,_________ (47) When this happens, hundreds of languages that are spoken by only a few die out.
Scholars believe there are around 6,000 languages around the world, but more than half of them could die out within the next 100 years. There are many examples, Araki is a native language of the island of Vanuatu, located in the Pacific Ocean. It is spoken by only a few older adults，so like Catawba，Araki will soon disappear. Many languages of ethiopia will have the same fate because each one has only a few speakers. _________ (48) In the Americas, 100 languages, each of which has fewer than 300 speakers, are dying out.
Red Thunder Cloud was one of the first to recognize the danger of language death and to try to do something about it. He was not actually born into the Catawba tribe, and the language was not his mother tongue._________ (49). The songs he sang for the Smithsonian Institution helped to make Native American music popular. Now he is gone, and the language is dead.
What does it mean for the rest of us when a language disappears? When a plant insect or animal species dies, it is easy to understand what has been lost and to for the balance of the natural word. However, language is only a product of the mind. To be the last remaining speaker of a language，like Red Thunder，must be a peculiarly lonely destiny, almost as strange and terrible as being the last surviving member of a dying species.________ (50)

Underground Coal Fires
Coal burning deep underground in China, India and Indonesia is threatening the environment and human life, scientists have warned, these large-scale underground (51) blazes cause the ground temperature to heat up and kill surrounding vegetation, produce greenhouse gases and can even (52) ignite (点燃) forest first, a panel of scientists told the annual meeting of the American Association For the Advancement of Science in Denver. The resulting release (53) of poisonous elements like arsenic and mercury can also pollute local water sources and soils, they warned.
“Coal fires are a global catastrophe,” said Associate Professor Glenn Stracher of East Georgia College in Swainsboro, USA, But surprisingly (54) few people know about them.
Coal can heat up on its own, and eventually catch fire and burn, if there is a continuous oxygen supply. The heat produced is not cause to disappear (55) and, under the right combinations of sunlight and oxygen, can trigger spontaneous (白发的) catching fire and burning. This can occur underground, in coal stockpiles, abandoned mines or even as coal is transported. Such (56) fires in China consume up to 200 million tons of coal per year, delegates were told. In comparison (57), the U.S. economy consumes about one billion tons of coal annually, said Stracher, whose (58) analysis of the likely impact of coal fires has been accepted for publication in the International Journal of Coal Ecology. Once (59) underway, coal fires can burn for decades, even centuries. In the process, they release large volumes (60) of greenhouse gases poisonous fumes and black particles into the atmosphere.
The members of the panel discussed the impact (61) these fires may be having on global and regional climate change, and agreed that the underground nature of the fires makes them difficult to detect (62).
Ultimately, the remote sensing and other techniques should allow scientists to estimate (63) how much carbon dioxide these fires are emitting. One suggested method (64) of containing the fires was presented by Gary Colaizzi, of the engineering firm Goodson, which has developed a heat-resistant grout (a thin mortar used to fill cracks and crevices), which is designed to be pumped into the coal fire to cut off (65) the oxygen supply.
