Ask the tourists from around the world that flood into Yellowstone National Park what they most hope to see, and their answer is often the same：a grizzly bear. “Grizzly bears are re-occupying large areas of their former range，” says bear biologist Chris Servheen. As grizzly bears expand their range into places where they haven't been seen in a century or more, they're increasingly being sighted by humans. The western half of the U．S.was full of grizzlies when Europeans came, with a rough number of 50,000 or more living alongside Native Americans. By the early 1970s, after centuries of cruel and continuous hunting by settlers, 600 to 800 grizzlies remained on a mere 2 percent of their former range in the Northern Rockies. In 1975, grizzlies were listed under the Endangered Species Act. Today, there are about 2,000 or more grizzly bears in the U．S.Their recovery has been so successful that the U．S.Fish and Wildlife Service has twice attempted to de-list grizzlies, which would loosen legal protections and allow them to be hunted. Both efforts were overturned due to lawsuits from conservation groups. For now, grizzlies remain listed. Obviously, if precautions (预防) aren't taken, grizzlies can become troublesome, sometimes killing farm animals or walking through yards in search of food. If people remove food and attractants from their yards and campsites，grizzlies will typically pass by without trouble. Putting electric fencing around chicken houses and other farm animal quarters is also highly effective at getting grizzlies away. “Our hope is to have a clean, attractant-free place where bears can pass through without learning bad habits，” says James Jonkel, longtime biologist who manages bears in and around Missoula. 　　 [真题再做] 语篇解读：本文是一篇说明文。文章主要介绍了美国灰熊从多变少的发展过程以及在法律的保护下，灰熊数量的增长，并探讨了针对灰熊的保护方案。 1．How do Americans look at grizzlies? A．They cause mixed feelings in people. B．They should be kept in national parks. C．They are of high scientific value. D．They are a symbol of American culture. 解析：选A　细节理解题。根据第一段内容可知，人们对灰熊既怕又爱。由此可见，人们对它们的感情很复杂，故A项正确。 2．What has helped the increase of the grizzly population? A．The European settlers' behavior. B．The expansion of bears' range. C．The protection by law since 1975. D．The support of Native Americans. 解析：选C　推理判断题。根据第三段尾句和第四段首句可以推断，灰熊数量增长与1975年以来的法律保护息息相关，故C项正确。 3．What has stopped the U．S.Fish and Wildlife Service from de-listing grizzlies? A．The opposition of conservation groups. B．The successful comeback of grizzlies. C．The voice of the biologists. D．The local farmers' advocates. 解析：选A　细节理解题。根据第四段的“Both efforts were overturned due to lawsuits from conservation groups.”可知，动物保护组织的反对阻止了美国鱼类及野生动物管理局将灰熊从《美国濒危动物法案》中除名，故A项正确。 4．What can be inferred from the last paragraph? A．Food should be provided for grizzlies. B．People can live in harmony with grizzlies. C．A special path should be built for grizzlies. D．Technology can be introduced to protect grizzlies. 解析：选B　推理判断题。根据最后一段的“If people remove food and attractants ...is also highly effective at getting grizzlies away.”可以推断，人类可以和灰熊和谐共处，故B项正确。 [多维提能] 一、题型思维建模 推理判断题解题攻略(以第4题为例) 1．警惕易错易误——鱼目混珠 本题易误选C。部分考生受“Our hope is to have a clean, attractant-free place where bears can pass through without learning bad habits”的干扰，就误认为这是在描述应为灰熊修建一条特殊的道路，从而误选C项。 2．内化题型技法——运用逻辑分析解题 解答推理判断题时，要从设题所涉及的文章内容出发，综合利用文章中提供的细节、事实并根据上下文提供的线索进行逻辑分析，尤其要读透文章字里行间的含义，即透过表面认识本质，从而通过自己的推理、判断和引申来得出正确答案。 以本题为例，可定位到最后一段。根据该段内容可知，如果人们采取一些方法，这样灰熊就不会带来麻烦，可推断出人们可以和灰熊和谐相处。 二、词汇拓展训练 1．因境辨义(写出下列黑体词在文中的词性及含义) ①(熟词生义)As grizzly bears expand their range into places where they haven't been seen in a century or more, they're increasingly being sighted by humans.v.看到；看见 ②(一词多义)The western half of the U．S. was full of grizzlies when Europeans came, with a rough number of 50,000 or more living alongside Native Americans.adj.粗略的，大致的 ③(一词多义)Obviously, if precautions (预防) aren't taken, grizzlies can become troublesome, sometimes killing farm animals or walking through yards in search of food.v.采取(措施)，采用 2．词块积累(写出下列词块在文中的汉语意思) ①flood into　　　　　　 涌入 ②be full of 充满 ③by the early 1970s 到20世纪70年代初 ④due to 由于；因为 ⑤in search of 寻找 ⑥be effective at 在……方面有效 三、长难句式破译 Grizzly bears, which may grow to about 2.5m long and weigh over 400kg, occupy a conflicted corner of the American psyche — we revere them even as they give us frightening dreams. 抓标志：关系代词which；从属连词as 判类型：复合句(含一个定语从句)＋破折号＋复合句(含一个状语从句) 试翻译：灰熊可以长到2.5米长，体重超过400公斤，在美国人心中占据着一个矛盾的角落——我们敬畏它们，尽管它们会给我们带来可怕的梦。 学科网（北京）股份有限公司 $$
