理应；有义务；应当（正式）

It behooves every citizen to obey the law.

每一位公民都理应遵守法律。

2.to be useful or advantageous for someone to do something

有益于；对… 有利

It would behoove you to prepare well before the job interview.

面试前好好准备将会对你大有好处。

源自古英语 behōfian，含义为 “需要、有益于”。

无拆分前缀，同源名词：behoof n. 利益、益处。

联想记忆：这个词几乎永远只用固定句型 it behooves sb to do sth，看到 it 开头就要条件反射想起 “某人理应做某事”。

领导理应认真倾听民众关切的问题。

it behooves sb to do sth 某人理应做某事

it ill behooves sb to do sth 某人不该做某事（带有责备语气）
