① 用英文介绍北极熊

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– 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.

Polar Bear Status Report
Polar bears are a potentially threatened (not endangered) species living in the circumpolar north. They are animals which know no boundaries. They pad across the ice from Russia to Alaska, from Canada to Greenland and onto Norway's Svalbard archipelago. No adequate census exists on which to base a worldwide population estimate, but biologists use a working figure of perhaps 22,000 to 25,000 bears with about sixty percent of those living in Canada.

In most sections of the Arctic where estimates are available, polar bear populations are thought to be stable at present. Counts have been decreasing in Baffin Bay and the Davis Strait, where about 3,600 bears are thought to live, but are increasing in the Beaufort Sea, where there are around 3,000 bears.

In the 1960s and 1970s, polar bears were under such severe survival pressure that a landmark international accord was reached, despite the tensions and suspicions of the Cold War. The International Agreement on the Conservation of Polar Bears was signed in Oslo, November 15, 1973 by the five nations with polar bear populations (Canada, Denmark which governed Greenland at that time, Norway, the U.S., and the former U.S.S.R.).

The polar bear nations agreed to prohibit random, unregulated sport hunting of polar bears and to outlaw hunting the bears from aircraft and icebreakers as had been common practice. The agreement also obliges each nation to protect polar bear denning areas and migration patterns and to conct research relating to the conservation and management of polar bears. Finally, the nations must share their polar bear research findings with each other. Member scientists of the Polar Bear Specialist Group meet every three to four years under the auspices of the IUCN World Conservation Union to coordinate their research on polar bears throughout the Arctic.

With the agreement in force, polar bear populations slowly recovered. The Oslo agreement is one of the first and most successful international conservation measures enacted in the 21st century.

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.
在挪威最北端北极圈Svalbard群岛，人们发现了一只北极熊的尸体，研究人员认为它的死因是气候变化所造成的。
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.
四月份挪威极地研究所在帮它检查做标记时，这只北极熊的健康状况还很不错。但是，当一队探险者7月偶然发现它时，早已瘦成了皮包骨。
"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."
“从它的卧姿来看，这只北极熊饿得倒了下来，最后死在了这里。”阿尔伯塔大学的兼职教授，同时也是北极熊专家的伊恩·斯特林博士告诉《卫报》记者，“外部迹象显示它的身体已没有任何脂肪，只剩下一具皮包骨。”

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.

Unlike Black and Grizzly bears, which are primarily nocturnal, the Polar Bear may be active at any time of the day or year, searching for prey on long summer days and sometimes on long winter nights. Adaptations to its Arctic habitat include its fur color, which blends with the snowy environment and so provides useful camouflage for capturing prey; its large size, which helps maintain body temperature by recing surface-heat loss; and its furred feet, which insulate against cold and provide traction on icy surfaces. Because the hairs of its waterproof coat are hollow, they are especially insulating and increase the bear's buoyancy when swimming. An excellent swimmer, it paddles at about 6 1/2 mph (10 km/h) with the front feet only, hindfeet trailing-a trait unique among four-footed land animals-and can remain submerged for about two minutes. While swimming or treading water, it stretches its long neck for a better view, as it does on land. Owing to the scarcity of plants in its icy habitat, the Polar Bear is the most carnivorous North American bear, with canine teeth larger and molariform teeth sharper than those of other bears. An acute sense of smell enables the Polar Bear to locate prey even when it is hidden by snow drifts or ice. It stalks young seals and Walruses, and sometimes alt seals, often by swimming underwater to their ice floes. While hair seals are its staple, it also feeds on fish, birds, bird eggs, small mammals, dead animals (including whales), shellfish, crabs, starfish, and mushrooms, grasses, berries, and algae, when available. The Polar Bear hollows out a winter den in a protected snowbank, where it retires in a lethargic condition. Females den from November to March, ring which time they give birth. Males den for much shorter periods, usually from late November to late January, but may be abroad occasionally at any time of the year. Cubs remain with their mother about a year and a half, denning with her the winter after their birth. The lowlands of Hudson Bay and James Bay, one of the world's largest denning areas for Polar Bears, is the only known region where Polar Bears den in earth rather than in snow. They excavate caves in lake and stream banks and peat hummocks by digging down to the permafrost. This area is unusually far south for the species, and it is believed that they use the permafrost dens again in summer to cool off. No large denning areas have yet been found in Alaska; some Polar Bears in that region may winter in Siberia, drifting across to Alaska on ice floes in spring. Polar Bears are a source of food and hides for Native Americans. 答案补充 英文好自己从中间找到答案！

⑩ 英文的介绍北极熊英文

The polar bear (Ursus maritimus) is a bear native largely within the Arctic circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest carnivore species found on land. It is also the largest bear, together with the omnivore Kodiak bear which is approximately the same size.[3] An alt male weighs around 350– kg (770–1,500 lb),[4] 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.[5] Although most polar bears are born on land, it spends most of its time at sea, hence its name meaning "maritime bear", and can hunt consistently only from sea ice, spending much of the year on the frozen sea.
