把这首诗翻译成英文，并解释其中的隐喻和象征意义。


《登高》
风急天高猿啸哀，渚清沙白鸟飞回。
无边落木萧萧下，不尽长江滚滚来。
万里悲秋常作客，百年多病独登台。
艰难苦恨繁霜鬓，潦倒新停浊酒杯。
Ascending Heights

The wind is strong and the sky high, monkeys wail mournfully,
The water is clear, the sand white, and birds fly back.
Countless dead leaves rustle down, while the Yangtze River keeps rolling on,
Being a traveler in melancholy autumn for thousands of miles, I've suffered illness for many years, but I'm climbing the tower alone.
Through hardships and agony, my hair has turned white, but I decided to stop drinking.
