Over millennia, rain and ice carved the rock into a landscape of spires and canyons. 千万年后 雨水和冰川 已将岩石雕琢成尖峰与峡谷
Nearly half of all cubs die in their first year out on the ice. 大约有近一半的幼熊 会在第一年的冰上历险中丧生
for a few miles from the coast the ice is already splitting. 离岸几英里远的海面上 冰层已经开始崩裂
And she must get there before the ice breaks up. 因此它必须在冰层破碎之前到达那里
