This book is full of holes/这本书里全是洞

You may not have noticed, but our surroundings are full of all kinds of holes—holes in socks, potholes in the ground, holes in Monstera leaves; there are also blue holes underwater, holes in airplane windows, holes that can be seen from space... Whether big or small, strange or ordinary, annoying or useful, life would be completely different without these holes.

你可能没有注意过，但我们的身边充满了各种各样的洞——袜子上的破洞、地面的凹坑、龟背竹叶子上的洞；还有水下的蓝洞、飞机舷窗上的洞、能从太空中看到的洞……无论是大是小，无论奇特还是普通，无论讨人厌还是很有用，要是没有这些洞，生活可就完全是另一番模样了。
