動物的叫聲

Advanced 彭蒙惠英語 April 2006中有篇
"Experience the Boundary Waters Canone Area"，
讓人體會遠離城囂，
親近大自然的喜悅。
記得曾看過這樣的句子:
The world is a book and those who do not travel read only a page.

儘管如此，
透過文章，
似乎也能感受自然之美與奧妙。
例如
有一段描述the sound of serenity:
...At night, the sawing of crickets prives white noise, along with the steady squeaking of bark beetles and the whine of mosquitoes, revving up like tiny Harleys. 
很生動的描述，
讓我似乎聽到大自然的天籟之聲。
