英语词汇knockout blow punch的起源、历史背景-英语词源词典

knockout blow (punch). A boxing blow that knocks its re- ceiver unconscious. In scientific terms, according to the New York Times (September 15, 2005), “when a fighter is hit on the tip of the chin, his head swivels with such force, his brain vi- brates inside his skull. That movement stretches nerve tissues in the brain, which then causes a concussion.” The same source quotes a pugilist describing how a knockout blow feels: “It feels like you die and then come back to life. It doesn’t hurt. Its just very dark, very black, and then you wake up. It could be 20 sec- onds or 30 seconds that go by, or it could be 10 minutes. You don’t know how much time passes.” See chin.
