英语听力：自然百科 黄石公园的夏天 Yellowstone—17

 They are vast smoke plumes¹. Yellowstone is burning. Throughout the summer, the dry lodgepole pines have become like a tinderbox, and lightening has struck the match. The worst wild fires will burn for weeks. In 1988, a third of Yellowstone burnt in a single summer. Devastation².

 

Animals that depend on these forests will starve this winter. But Yellowstone itself has a longer perspective. Ashes fertilize³ the soil, and fire opens it up to sunlight. As the forests regenerate⁴, new life finds opportunity.

 

In August, fledgling hummingbirds⁵ gorge⁶ in fields of fireweed that have risen from the forest's ashes. For them, the summer is already nearly over. They must chase the sun south before winter returns.
