雙語(yǔ)常用典故： Cast pearls before swine 對(duì)牛彈琴;明珠暗投;白費(fèi)好意

To Cast pearls before swine 的意思是“珍珠投在豬玀前面”。swine 是個(gè)舊詞，書(shū)面詞，即今為 pigs,不過(guò) swine單復(fù)同形，本句為復(fù)數(shù)。

這個(gè)成語(yǔ)源自《新約。馬太福音》第 7 章：“Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you”. 由 于 to cast pearls before swine, 比喻確切，在后世不斷引用中而成為一個(gè)國(guó)際性成語(yǔ)，常用來(lái)表示to offer sth valuable or beautiful to those who can't appreciate it; to give what is precious to those who are unable to understand its value 等意思，含有輕蔑嘲笑色彩。按其字面意義，這個(gè)成語(yǔ)與漢語(yǔ)成語(yǔ)“明珠暗投”相似，但是寓意不同，基本上不對(duì)應(yīng)；按一比喻意義， 它相當(dāng)于“對(duì)牛彈琴”，“向驢說(shuō)經(jīng)”“一番好意給狗吃”“狗咬呂洞賓，不識(shí)好人心”等。
