句子：他隨時準備為公益而犧牲個人利益。

誤譯：He is always ready to sacrifice his personal interest for public good.

正譯：He is always ready to sacrifice his personal interest for public welfare.

解釋：作為名詞，good 有兩個意思：一是好處、益處、利益；二是商品、產品等。public good 不是“公共利益”。public good 與 private good 相對立，前者是“公共物品”，后者是“私人物品”。如：

公共物品的最佳實例之一是國防。

One of the best examples of a public good is national defense.

“公益”的意思是“公共利益，多指衛生、救濟、慈善等群眾福利事業”。可譯為 public welfare, public benefit, public interest, general welfare, common well-being, commonweal。如：

這位慈善家每年都籌集固定數額的基金用于公益。

The philanthropist annually raises a fixed amount of fund for public welfare.

“公益事業”可譯為public service, public welfare undertaking。如：

姚明還投身慈善工作和公益事業，成為一個著名的體育明星。

Yao Ming has also thrown himself into charity work and public service, and become a famous sports celebrity.

“公益廣告”可譯為 public service advertisement, public welfare ad。如：

廣告可以分為商業廣告和公益廣告。

Advertisements can be divided into commercial advertisements and public service advertisements.

“有公益精神的”或“熱心公益的”可譯為 public-spirited。如：

她是一個熱心公益的人，急切糾正那些我們都看得見但是容易忽視的錯誤行為。

She is a public-spirited person who is eager to correct the wrongs that we all see but we easily overlook.
