      Quaking aspens like these in the Elk Mountains of western Colorado, whose leaves tremble in the slightest wind, are common across North America. Known for tolerating poor soils and cold climates, aspens flash yellow against their white bark in an unmistakable sign of coming winter.

      像這些在科羅拉多州西部的美洲赤鹿山顫動(dòng)的楊樹在整個(gè)北美非常普遍。它們的葉子會(huì)在微風(fēng)中顫抖。顫楊以能忍耐貧瘠土壤和寒冷氣候而聞名。以它們的白色樹皮為襯托，顫楊樹林間閃爍著黃葉，預(yù)示著即將來(lái)臨的冬天。
