pose

Compared meaning: to pretend to be someone else (verb).

比较义项：假装、冒充（成某人）（动词）。

• pose 本词

  Weaker and more general: to present oneself as a type of person or thing, often briefly or for a specific purpose, not necessarily a named individual.

  语气较弱、含义较泛：指把自己装扮成某一类人或某种身份，往往是短暂的或出于特定目的，不一定是冒充某个具体的人。

  The scammer posed as a bank employee to get her account details.

  这个骗子假扮成银行职员以骗取她的账户信息。

• impersonate

  Stronger and more specific: to imitate a particular real person's identity, voice, or manner closely, often illegally or as performance.

  语气更强、含义更具体：指精确模仿某个真实存在的人的身份、声音或举止，常带有非法性质，或作为一种表演。

  It's a crime to impersonate a police officer in most countries.

  在大多数国家，冒充警察是违法行为。

Pose and impersonate both mean to pretend to be someone or something else. Pose is weaker and more general: presenting oneself as a type of person, often briefly. Impersonate is stronger and more specific: closely imitating a real person's identity or voice, to deceive.

两者都指假装成不是自己的身份，但 impersonate 更强调具体冒充某个人（尤指为了欺骗或表演），而 pose 语气较轻，只需摆出某种姿态或身份即可，不一定涉及具体某个人。这里不比较 pose 的“摆姿势（拍照）”这一义项。
