题文
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(语言学的) 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(详尽的) 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.

解析
本文介绍了研究全球本地语言消失所带来的严重影响，人们挽救本土语言的努力和使本地语言上消失的原因。
小题1:推断题：通读全文后可知本文主要研究全球本地语言消失所带来的严重影响，人们挽救本土语言的努力和使本地语言上消失的原因，故选A。
小题2:细节题： developing发展；changing改变；increasing增加；Disappearing消失。通读全文可知是巨额本土语言正在消亡，只有D项语文以最贴切，故选D。
小题3:细节题：根据Native people had an intimate(详尽的) knowledge of their environment that was lost when their language disappeared当土著人的语言消失的时候，他们关于环境的详细知识也消失了，故选D。
小题4:推断题：B、D项在文中均有提到，A、C项未被提及，故A、C是错误的。根据while there they found a man with knowledge of the Amurdag language, which had previously been thought extinct他们发现有一个了解Amurdag语言的人,此前这种语言被认为已经灭绝。故这个消息是好消息，故选B。
考点
据考高分专家说，试题“The world’s native l.....”主要考查你对 [政治经济类阅读 ]考点的理解。政治经济类阅读
政治经济类文章的概念：
要做好这类阅读，平时就要注意了解国内外发生的政治经济大事，掌握一定背景知识，对这类文章的叙述特点及内容安排有一定了解，还要扩展这方面的词汇。阅读这类文章，要抓住文章的核心，即文章整体和各段主要在说什么，也要注意段落之间的逻辑关系。
如何备考政治经济类阅读理解题：
【题型说明】政治经济类阅读文章是高考常选材料之一。该类文章时代气息浓郁，语言鲜活，但熟字新义词、超纲词及专业词语多，长句、难句多。政治类文章大多数是同学们感性趣的内容，读起来倒有似曾相识的感觉，经济类文章读起来就像是雾里看花，文章看完，一头雾水。再加之这类文章的命题侧重于词义猜测、推理判断和文章主旨，同学们对这类题材是望而生畏。
【备考策略】建立心理优势。针对不同体裁的文章，我们要采取相应的阅读方法和技巧。政治类文章多采用记叙文形式，我们可采取“顺读法”，以便抓关键语句，领会文章主旨；而经济类文章则多采用说明文形式，我们则可以采取“逆读法”，先读试题，再从文章中查找有用信息。若遇到的确难读的材料。千万不用着急，因为你觉得难，其他人也一定是同感。在高考前，我们就要有这种心理准备，高考试卷肯定有一、两篇难以阅读的材料。不过，我们平时可以有意识地从报刊杂志上找一些较难的阅读材料来阅读，以培养自己迎难而上的心理素质。
【答题方法】
1、寻找主干：
根据英语中五种基本句型结构，把句子中的主语、谓语、宾语、表语等主要成分找出来，其他成分如定语、状语、补语等则易于理解。找到了句子主干，句子的意思至少明白了一半。
2、剔除从句：
在一个长句中可能会出现若干个从句，在理解时，如果把各个从句剔除出来单独理解，然后把大意拼凑起来，整个长句的意思就会明白六、七分。
3、辨别分句：
一个长句如果是由几个并列、转折、递进、对比关系的分句组成，句中往往有表示这些分句关系的连接词，只要能弄清楚分句和分句之间的逻辑关系，再把各层分句的意思加以连贯，整个长句的句意基本上能跃然脑中。
4、寻找关键词：
如果一个句子看完，一点句意的感觉也没有，下下策就是抓住句中的关键词，通过关键词大体弄懂这个长句的意思。
