And to prevent crunching footsteps from revealing his presence, 为了避免踩雪的脚步声暴露行踪
Winter in the mountains returns fast and hits hard. 山里的冬天来得迅猛
As they rub, each leaves an individual and recognisable scent. 每只熊摩擦时都会留下易于辨认的独特气味
and will travel long distances to visit them. 他们会长途跋涉 去找喜欢的树
and the bears are keen to shed their thick winter coats. 灰熊急切地想脱下它们厚重的冬衣
In the Rockies, seasonal change is swift and dramatic. 落基山脉的季节变换迅速而突然
And they have another reason to keep moving. 他们继续前行还有另一个原因
And while they were half-asleep in the depths of winter, 他们在隆冬半梦半醒之际
And when spring comes, they emerge. 待春天来临 它们就出洞了
