英语听力:自然百科 黄石公园的夏天 Yellowstone—1(在线收听

 For six months, Yellowstone endures an unrelenting winter.

An ice world of hunters and hunted.
 
But now footsteps on the slopes of a mountain herald a change in the season.
 
The sun regains its strength.Water flows again.
 
The race begins to recover winter's losses, to play, learn, and breed. But the summer ahead will be fleeting, and far from easy, in this unpredictable wilderness.
 
It's April, the land lies exhausted by winter. Everything is waiting for the return of the sun's warmth.
