雙語常用典故： Cast pearls before swine 對牛彈琴;明珠暗投;白費好意

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

這個成語源自《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國際性成語，常用來表示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，這個成語與漢語成語“明珠暗投”相似，但是寓意不同，基本上不對應(yīng)；按一比喻意義， 它相當(dāng)于“對牛彈琴”，“向驢說經(jīng)”“一番好意給狗吃”“狗咬呂洞賓，不識好人心”等。

Eg .She read them Shakespeare, but it was casting pearls before swine

I won't waste good advice on John any more because he never listens to it. I won't cast pearls before swine.
