I'm gonna pick a book that I read recently, Overstory by Richard Powers.

理查德．包沃斯的《上层林》。

Scientists conceptualize the Amazon as four ecological layers: the forest floor, the understory, the canopy and the overstory.

科学家将亚马逊雨林分为四个生态层：雨林地表、下层植被、树冠层和上层林冠。

I have to admit that my fiction reading has declined a lot in recent years so our family agreed we would all read together on vacation, and luckily " The Overstory" is one we chose.

不得不承认， 这几年我的小说阅读量下降了很多， 所以我们家人同意我们一起在假期一起阅读， 幸运的是我们选择了“The Overstory” 。
