Talent, hard work and sheer tenacity are all crucial to career success.事业要成功，才能、勤奋和顽强的意志都至关重要。 crucial 关键性的来自cross，十字，分叉口，引申义关键的。 crucialcrucial: see crosscrucial (adj.)1706, "cross-shaped," from French crucial, a medical term for ligaments of the knee (which cross each other), from Latin crux (genitive crucis) "cross" (see cross (n.)). The meaning "decisive, critical" (1830) is extended from a logical term, Instantias Crucis, adopted by Francis Bacon (1620); the notion is of cross fingerboard signposts at forking roads, thus a requirement to choose." |
