英语听力：自然百科 黄石公园的夏天 Yellowstone—1

 For six months, Yellowstone endures an unrelenting winter.

An ice world of hunters and hunted.

 

But now footsteps on the slopes of a mountain herald¹ a change in the season.

 

The sun regains² its strength.Water flows again.

 

The race begins to recover winter's losses, to play, learn, and breed. But the summer ahead will be fleeting³, and far from easy, in this unpredictable wilderness⁴.

 

It's April, the land lies exhausted⁵ by winter. Everything is waiting for the return of the sun's warmth.
