eagle-eyed

【英文解釋】very keen sighted

【中文解釋】眼里敏銳的，目光炯炯的

【短語來源】 Legend has it that the eagle has the sharpest eyesight of all birds. When its sight grows dull with age it flies up towards the sun, and, by staring at the sun, which only it can do, it burns away all the cloudiness of age. This story has been known and referred to for as long as we have written records of English, having been introduced to the Anglo-Saxons by Christian missionaries. However, eagle eye or eagle-eyed, used without reference to the legend, to mean(keeping)a sharp watch on something has only been used as an expression since the early 19th century.

傳說鷹是眼睛最銳利的鳥。當(dāng)它老了視力變差時(shí)，它就會(huì)飛向太陽。并且直視太陽，當(dāng)然，只有鷹有這種本領(lǐng)。通過這種方式，它能讓歲月帶給它的朦朧視線重新變得清晰無比。
這個(gè)故事的歷史可以追溯到英語文字記載出現(xiàn)之時(shí)，并由基督教傳教士傳入英國祖先盎格魯撒克遜人中。
而自19世紀(jì)以來，不論是分開的eagle eye還是連起來的eagle-eyed，都是指在某件事上目光敏銳。

【有例有句】Nothing can escape our teacher's eagle eye.

任何事情都逃不過我們老師銳利的眼光。
