 ♣ bright, clever, intelligent, shrewd, smart, wise
　这组形容词的共同意思是“聪明的”“有智慧的”“英明的”“有头脑的”。其区别在于：
1. bright一般指年轻人，尤指小孩的聪明、机警；wise指“有智慧的”“英明的”“有头脑的”; smart指“头脑敏捷的”“精明老练的”，常指思维能力很强，办事巧妙，能圆滑地处理人际关系等，有时也带有表面的或肤浅的色彩；clever指“聪明的”“伶俐的”“能干的”，尤指很有理解或学习能力的；shrewd指“机灵的”“敏锐的”“精明的”，表示谙于世故，对事物浅尝辄止，遇事老谋深算，从不忽略个人私利；intelligent指某人是“聪明的”“智力好的”，善于作出正确的判断。例如：
　In some schools, the bright pupils tutor the dull ones.　在一些学校里，一些聪明的学生辅导迟钝的学生。
　She was wise to their scheme.　她了解他们的诡计。
　He is so smart that he will jump at the chance.　他这个人很有头脑，不会错过这个机会的。

 ♣ bright, light
　这两个词都可表示“明亮的”。bright指东西发光或反光而明亮，light则指光线充足而明亮。

　bright　可和shine连用，用作副词，表示“明亮地”，相当于brightly，不过有的语法学家认为此处的bright是形容词。例如：
　The stars were shining bright.　星光灿烂。
　She asked which of the two lamps shone brighter.　她问两盏灯中哪盏灯照得较亮。
　再比较：

　［同义词］ brilliant, gleaming, shining, shiny, cheerful, happy, lively, intense, vivid, clever, intelligent, keen, encouraging, favourable, promising
　［反义词］ dim, dull, backward, boring, colourless, slow, stupid
