In just a few days, 几天时间内

108. Bears that have hibernated throughout these peaks
     这片山峰之间冬眠的灰熊
109. now all descend to the valleys, where spring comes earliest.
     现在都下山了 那里的春天来得更早
110. In the Rockies, seasonal change is swift and dramatic.
     落基山脉的季节变换迅速而突然
111. In just a few days,
     几天时间内
112. the slopes turn from white to green.
     白雪皑皑的山脉便会绿意盎然
113. Meadows that only a few weeks ago were buried beneath the snow
     几周前还深埋在冰天雪地里的牧场
114. are now full of life.
     现在生机勃勃
