Let by her nose, she risks a 300-pound bulk on the thin ice of the bend in the Snake River.

在她灵敏鼻子的引导下,这只300磅重的庞然大物在蛇河薄冰上步履蹒跚简直充满了危险。

It doesn't look promising, but her cubs follow with only a little hesitation.

看起来并非会有多幸运,但是她的幼崽们带着一些犹豫不定在追寻着母亲。

With paws that can knock down an elk, she feels delicately in the water, a fish frozen beneath the ice by this cold winter.

厚实的爪子可以拍倒一只麋鹿,这位母亲感觉水中有些微妙,那是一条鱼在这个寒冷的冬天被冻在了冰层下面。

One fish won't feed the family, but she knows there are almost certainly more.

区区一条鱼可喂不饱这个家庭,但她知道几乎肯定会有更多。

The cubs must learn to find them.

而幼崽们必须学会找到食物。
