Question

The world’s native languages are dying out at an unprecedented(空前的) rate, taking with them irreplaceable(不能替代的) knowledge about the natural world, according to a new study.
The study identified five global “hot spots” where languages are vanishing faster than anywhere else ---- eastern Siberia, northern Australia, central South America, the US state of Oklahoma and the US Pacific Northwest. “Languages are suffering a global extinction crisis that greatly goes beyond the pace of species extinction,” linguistics(語言學的) professor David Harrison noted, who said half of the world’s 7,000 languages were expected to disappear before the end of the century.
Native people had an intimate(詳盡的) knowledge of their environment that was lost when their language disappeared, along with other certain things often unfamiliar to us, Harrison stressed. “Most of what we know about species and ecosystems is not written down anywhere, it’s only in people’s heads,” he said. “We are seeing in front of our eyes the loss of the human knowledge base.”
Harrison was one of a team of linguists who carried out the study. The researchers traveled to Australia this year to study native languages, some of the most endangered. According to Harrison, in Australia, they were heartened to see a woman in her 80s who was one of the only three remaining speakers of the Yawuru language passing on her knowledge to schoolchildren. He said such inter-generational exchanges were the only way native languages could survive. “The children had elected to take this course, no one forced them,” he said. “When we asked them why they were learning it, they said,‘This is a dying language, we need to learn it’.” Also, while there they found a man with knowledge of the  Amurdag  language, which had previously been thought extinct.
The researchers said all five of the hot spots identified were areas that had been successfully colonized and where a dominant language such as Spanish or English was threatening native tongues.

【小題4】B

解析試題分析：本文介紹了研究全球本地語言消失所帶來的嚴重影響，人們挽救本土語言的努力和使本地語言上消失的原因。
【小題1】推斷題：通讀全文后可知本文主要研究全球本地語言消失所帶來的嚴重影響，人們挽救本土語言的努力和使本地語言上消失的原因，故選A。
【小題2】細節(jié)題： developing發(fā)展；changing改變；increasing增加；Disappearing消失。通讀全文可知是巨額本土語言正在消亡，只有D項語文以最貼切，故選D。
【小題3】細節(jié)題：根據(jù)Native people had an intimate(詳盡的) knowledge of their environment that was lost when their language disappeared當土著人的語言消失的時候，他們關于環(huán)境的詳細知識也消失了，故選D。
【小題4】推斷題：B、D項在文中均有提到，A、C項未被提及，故A、C是錯誤的。根據(jù)while there they found a man with knowledge of the Amurdag language, which had previously been thought extinct他們發(fā)現(xiàn)有一個了解Amurdag語言的人,此前這種語言被認為已經(jīng)滅絕。故這個消息是好消息，故選B。
