The white circle in the center of a target; a bull's eye.靶子中心的白点;靶心.—— vivian小歆查了一下,bull's-eye有这几个意思：1.最常见的意思是指 the small central circle on a target；a shot that hits this circle.靶心;打中靶心的一击;直接命中如：The archer's shot was a perfect bull's-eye.射手的那一箭正中靶心.引申的意思有：2.事物的关键,中心要点 3.击中要害的話(或行动) 4.(船侧的)圆玻璃窗;(建筑物的)小圆窗 5.牛眼灯 6.指一种糖球 —— 飛鳥川韦氏辞典给出的解释：bull's-eye noun 1 :a very hard globular candy 2 :a circular piece of glass especially with a lump in the middle 3 a :the center of a target also :something central or crucial b :a shot that hits the bull's-eye broadly :something that precisely attains a desired end 4 :a simple lens of short focal distance also :a lantern with such a lens 总之最常用的是“靶心”这个意思.个人建议查字典最好查英英解释,比较地道.有时候还易懂.
