A crab1 once left the sea-shore and went and settled in a meadow2 some way inland, which looked very nice and green and seemed likely to be a good place to feed in. But a hungry fox came along and spied the crab and caught him. Just as he was going to be eaten up, the crab said, "This is just what I deserve, for I had no business to leave my natural home by the sea and settle here as though I belonged to the land."

　　有一次，一只螃蟹離開(kāi)海邊，定居在內(nèi)陸的一塊草地上，那里看著很美，有青青的綠草，是個(gè)養(yǎng)分充足的好地方。然而，一只饑餓的狐貍走過(guò)來(lái)，看見(jiàn)螃蟹并捉住了他。就在狐貍將要吃掉他之前，螃蟹說(shuō)：“我真是活該，我沒(méi)有理由要離開(kāi)海邊那個(gè)天然的家，像陸地棲息的動(dòng)物一樣，偏要到這里來(lái)定居。”

　　知足才能常樂(lè)。
