According to IUCN's(世界自然保护联盟的) recent Red List of Threatened Species（受到威胁的物种）,the polar bear is listed as a “vulnerable” species that is threatened with extinction（灭绝）.
With its clean lines and white fur,the polar bear has an aesthetic appeal that's thoroughly modern.Ever since we saw those bears stuck on melting ice in Al Gore's An Inconvenient Truth,we hear the sad screams of a baby polar bear ringing in the back of our minds.
We should try our best to help Polar bears out of danger.They usually live on sea ice and am one of the few members of my family able to spend long amounts of time in water. 它们通常生活在海冰上,是为数不多的家庭成员能够花大量时间在水中。================================================They are very large with a huge, furry body. Their feet are designed for walking on ice and have five sharp claws made for holding onto food. Their stiff hair and fur help them swim well. 他们是非常大的与一个巨大的长着毛皮的身躯。他们的脚专门适合在冰上行走,五个尖尖的爪子用来抓住食物。他们的硬硬的头发和皮毛有利于他们很好的游泳。=========They normally eat seals but also can dine on walruses, mussels or even berries and seaweed. 他们通常吃海豹,但也能吃海象,蚌类,甚至是浆果和海藻
