『壹』 北极熊英文介绍,

The polar bear (Ursus maritimus) is a bear native to the Arctic Ocean and its surrounding seas.The world's largest predator found on land,an alt male weighs around 400–680 kg (880–1,500 lb),while an alt female is about half that size.Although it is closely related to the brown bear,it has evolved to occupy a narrow ecological niche,with many body characteristics adapted for cold temperatures,for moving across snow,ice,and open water,and for hunting the seals which make up most of its diet.As it can hunt consistently only from sea ice,the polar bear spends much of the year on the frozen sea,although most polar bears are born on land.
The polar bear is classified as a vulnerable species.Of the 19 recognized polar bear subpopulations,5 are declining,5 are stable,2 are increasing,and 7 have insufficient data.For decades,unrestricted hunting raised international concern for the future of the species; populations have rebounded after controls and quotas began to take effect.For thousands of years,the polar bear has been a key figure in the material,spiritual,and cultural life of Arctic indigenous peoples,and the hunting of polar bears remains important in their cultures.
The IUCN now lists global warming as the most significant threat to the polar bear,primarily because the melting of its sea ice habitat reces its ability to find sufficient food.Sea ice melting will also cause changes in their mating,and traveling patterns.The IUCN states,"If climatic trends continue polar bears may become extirpated from most of their range within 100 years." On May 14,2008,the United States Department of the Interior listed the polar bear as a threatened species under the Endangered Species Act.

『柒』 用英语介绍北极熊是濒危动物〔200单词

A polar bear carcass 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 tagged it. However, the animal was reced to skin and bones by the time a group of explorers happened upon its body in July.
"From his lying position in death the bear appears to simply have starved and died where he dropped," polar bear expert Dr. Ian Stirling, an adjunct professor at the University of Alberta, told The Guardian. "He had no external suggestion of any remaining fat, having been reced 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 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
