词汇	upbeat
词根词缀	词源： upbeat (adj.) "with a positive mood," 1947, apparently from the musical noun upbeat (1869), referring to the beat of a bar at which the conductor's baton is in a raised position; the "optimistic" sense apparently for no other reason than that it sounds like a happy word (the musical upbeat is no more inherently "positive" than any other beat).
