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 animal’s death.The starved polar bear in Norway was said to be in good health in April when the Norwegian Polar Institute examined and labeled it． However, the animal was reduced to skin and 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 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．

(答案→)D
解析：本文是一篇新闻报道。文章讲述了北极熊死亡的原因。气候变化是导致北极熊死亡的根源。
【小题1】D考查细节理解。根据文章第三段中的From his lying position in death the bear appears to simply have starved and died where he dropped, polar bear expert Dr. Ian Stirling可知，根据熊躺着的位置可知熊看起来饿死在它掉下来的地方。故选D。
【小题2】A 考查猜测词义。根据文章的最后一段中的The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species．可知，国际自然保护联合会目前把北极熊列为受威胁物种的红名单。这里受威胁和易受伤害为同义，故选A。
【小题3】D考查作者的态度。根据文章第一段中的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 animal’s death.可知，北极发现北极熊死尸令专家感到震惊，这说明作者关心北极熊。故选D。
【小题4】C 考查推理判断。根据文章的整体内容及标题气候变化的牺牲品可知，这是一篇新闻报道。故选C。此处 novel小说；A guidebook生活指南； A news report新闻报道；An advertisement广告。显然其它三项不合题意。
