北极熊生活在哪里

This island is covered with snow. No trees grow. Nothing has green leaves. The land is white as far as you can see. Then something small and round and black pokes up out of the snow.

这个岛被雪覆盖着。没有树木生长。 没有绿叶。一望无际的土地都是白色的。 然后一个又小又圆又黑的东西从雪里探了出来。

A black nose sniffs the air. Then a smooth white head appears. A mother polar bear heaves herself out of her den. A cub scrambles after her.

一只黑鼻子嗅着空气。然后一个光滑的白头出现了。一只北极熊妈妈从窝里爬了出来。 一只幼崽争先恐后地追着它。

When the cub was born four months ago, he was no bigger than a guinea pig. Blind and helpless, he snuggled in his mother's fur. He drank her milk and grew, safe from the long Arctic winter. Outside the den, on some days, it was fifty degrees below zero. From October to February, the sun never rose.

当这只幼崽四个月前出生时，它还没有一只豚鼠大。他又瞎又无助，蜷缩在妈妈的毛皮里。他喝了她的奶，安然度过了漫长的北极冬天。 有些日子，洞穴外面的气温是零下五十度。从十月到二月，太阳从不升起。

Now it's spring-even though snow still covers the land. The cub is about the size of a cocker spaniel. He's ready to leave the den. For the first time, he sees bright sunlight and feels the wind ruffle his fur. The cub tumbles and slides down icy hills. His play makes him strong and teaches him to walk and run in snow.

现在是春天了——尽管大地上还覆盖着雪。幼崽大约有一只可卡犬那么大。他准备离开洞穴了。第一次，他看到了明亮的阳光，感觉到风吹皱了他的皮毛。 幼崽翻滚着从冰冷的山上滑下来。他的玩耍使他变得强壮，并教会他在雪中行走和奔跑。

Like his mother, the cub is built to survive in the Arctic. His white fur will grow to be six inches thick-longer than your hand. The skin beneath the cub's fur is black. It soaks up the heat of the sun. Under the skin is a layer of fat. Like a snug blanket, this blubber keeps in the heat of the bear's body. Polar bears get too hot more easily than they get too cold. They stretch out on the ice to cool off.

和妈妈一样，幼崽也能在北极生存。 它的白色皮毛会长到6英寸厚——比你的手还长。幼崽皮毛下面的皮肤是黑色的。它吸收太阳的热量。皮肤下面是一层脂肪。就像一条舒适的毯子，这些脂肪可以保持熊身体的热量。 北极熊变热比变冷更容易。他们在冰上伸开四肢凉快一下。
