• smart 本词

  那真是聪明的一招——她避开了大家都中招的陷阱。

• intelligent

  更正式、更通用；强调整体的推理与理解能力，可用于人、动物或机器，不特指年轻或机灵。

Smart, bright, and intelligent all mean 'clever', but differ. Smart is casual, suggesting quick thinking or wit. Bright often describes students with natural talent and fast learning. Intelligent is more formal, describing overall reasoning ability. Other senses are not compared here.

这三个词都可表示“聪明”，但语气和适用对象不同：smart语气随口、日常，强调机灵、反应快；bright常用于形容学生或年轻人天资聪颖、学得快，也常带有前途光明的意味；intelligent更正式、更通用，强调整体的推理与理解能力，也可用于动物或机器。这里不比较smart表示“时髦、整洁”的义项，也不比较bright表示“明亮的”义项。
