Shyness is widely known as a feeling of human beings, while it also exists in certain tree species. This naturally occurring phenomenon is called “crown shyness” because the uppermost branches of certain tree species don't like to touch one another.
害羞被广泛认为是人类的一种感觉，而它也存在于某些树种中。这种自然发生的现象被称为“树冠羞避”，因为某些树种的最上面的树枝不喜欢互相碰触。
The intriguing behavior was first observed in the 1920s, and various hypotheses have been presented since then in an attempt to explain it. Some believe it occurs to reduce the spread of harmful insects. Others believe that trees are attempting to protect one another’s branches from getting cracked and broken in the wind, and it’s also been suggested that “crown shyness” happens so that trees can optimize light exposure in order to maximize the process of photosynthesis.
这个有趣的行为是在20世纪20年代首次被发现的，从那时起，（人们）提出各种各样的假设，试图来解释这一行为。一些人认为这是为了减少有害昆虫的传播，另一些人则认为树木是在试图保护彼此的树枝免受风的破坏，也有人提出“树冠羞避”的发生可以使树木优化光的照射，以最大限度地进行光合作用。
Despite these various theories, however, nobody knows for sure why this phenomenon occurs, but it serves to remind us of just how awesome Mother Nature can be.
