大象能用鼻子轻松地将一吨重的东西卷起来,但我们却常常发现,许多大象被安静地拴在小木桩上。它们完全可以扬鼻把木桩拔起,从而不被木桩所困。 专家注意到这个现象,他们解释说,大象幼小时常被铁链拴在铁桩上,当时不管用多大的力气去拉,铁桩对于幼象而言,是一座庞然大物,动也动 Elephants can easily roll up a ton of weight with their noses, but we often find that many elephants are quietly lying on small wooden posts.

No matter how much force was used to pull them, iron piles were a huge beast for young elephants.
