"Since I appointed a new department head, business has certainly improved." the boss smiled." The new fellow keeps an eagle eye on all aspects of our operations. He watches the staff with an eagle eye, too." Someone with an eagle eye watches things closely and carefully. Nothing escapes his attention.
“自從我任命了一個新的部門主任后,公司業(yè)績大幅提高,”老板得意地說“這個新人對公司的各項工作都認真負責,對員工的督促監(jiān)管也很嚴厲,眼睛像鷹般敏銳。”
鷹(eagle)有極佳的眼力,縱然盤旋于高空上,也能看見地下細小的獵物,于是給了我們"an eagle eye"這個用語,比喻某人有銳利的目光。
