题目：
A victim of climate change
A polar bear's dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the death. The starved polar bear in Norway was said to be in good bones by the time a group of explorers came across its body in July．
The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals．"From his lying position in death, the bear appears to simply have starved to health in April when the Norwegian Polar Institute examined and labeled it． However, the animal was reduced to skin and bones and died where he dropped," polar bear expert Dr. Ian Stirling, a professor at the University of Alberta said, "He had external suggestion of any remaining fat, having been reduced to little more than skin and bone．"
Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals． That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April．
Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change．
The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species．

题目分析：文章讲述了在挪威北部北极的一个岛上发现了一头北极熊，这件事使专家很震惊。从发现北极熊的地方看，是北极熊为了寻找食物在向北去的路上死掉的，他是为了寻找冰来作为他猎取海豹的平台才向北转移的，在些过程中因饥饿而死。这一事件是由气候的变化引起的，因为全球的气候变暖，使冰在减少，才使北极熊处于濒危境地。
小题1: D细节理解题。.. From his lying position in death, the bear appears to simply have starved to health in April when the Norwegian Polar Institute examined and labeled it。句意为：当挪威极地研究院在检测北极熊时发现，从他死的位置上可以看出，北极熊是在四月份因饥饿而死的。故答案为D。
小题2:A词义理解题。The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species．国际联盟自然保护机构将北极熊归类到了濒危物种的红色名单上。由此可知北极熊是易受攻击，受伤害的动物。dangerous 危险的，此处并非北极熊是危险的，而是处于危险之中。故答案为A。
小题3:D综合理解题。文中从发现北极熊开始到对动物检测，查找原因，对这件事情一直处在关注之中，同时也了解到，挪威自然研究院把北极熊划为濒危动物的行列。故作者对此事是关注的，所以答案应为D。
小题4:C段落理解题。文章从发现北极熊的尸体开始展开，经过对熊尸体的检测，推测出了是因气候变化而导致死亡的原因，同时指出了气候变暖使北极的冰在连年减少，2012年达到了新的纪录。所以这篇文章应出自于一篇报道。novel 小说,文章并非在讲一个故事；a guidebook 一本指导书，文章并未对事情作出指导；advertisement 广告，没有介绍什么产品，故答案应为C。
