【注释】本语略带贬义。据说，英国柴郡盛产干酪，当时 人们喜欢把干酪做成咧嘴笑的猫形，所以柴郡猫就被 传会“笑”了。在英国数学家和童话作家刘易斯?卡 洛尔(Lewis Carroll)所写的童话《爱丽丝漫游奇境 记》(Alice’s Adventures in Wonderland)里，爱丽斯在 公爵家的厨房里看见一只大猫咧着嘴笑，使她着实吃 了一惊，公爵夫人告诉她：“这只猫嘛，可是只柴郡 猫! [1]”这个习语从此就随着《爱丽丝漫游奇境记》流 传开来。变体：to wear or have a grin like a Cheshire cat; to smile like a Cheshire cat。出自《爱丽丝漫游奇境记》第6章，原文如下：“Please，would you tell me，” said Alice a little timidly, “Why your cat grins like that?” “It’s a Cheshire cat"，said the Duchess, “and that’s why.”
