请看看这根扫帚把，它现在灰溜溜地躺在偏僻的角落，而以前我曾在树林里碰见过它，那时它风华正茂，汁液充沛，枝叶繁盛。如今它完全变了样，却还有人自作聪明，想靠人类的手工同大自然竞争，拿来一束枯枝捆在它那早已干瘪的身上，结果是枉费心机，不过颠倒了它原来的位置，使它枝干朝地，根梢朝天，成为一株头朝下的树，然后落在干脏活累活的女仆们的手里使用。从此它受命运的摆布，把别人打扫干净，而自己却变得又脏又臭，在女仆们手里折腾多次之后，最后被扔出门外，或者作为引火的柴禾被投进火里。

In this mirror the most beautiful landscapes looked like boiled spinach, and the best persons were turned into frights, or appeared to stand on their heads; their faces were so distorted that they were not to be recognised; and if anyone had a mole, you might be sure that it would be magnified and spread over both nose and mouth.

最美丽的风景在这镜子里就会像煮烂了的菠菜；最好的人不是现出使人憎恶的样子，就是头朝下，脚朝上，没有身躯，面孔变形，认不出来。如果你有一个雀斑，你不用怀疑，它可以扩大到盖满你的鼻子和嘴。
