opt

Compared meaning: to pick or decide on something (verb).

比较义项：选择、愿意选做某事（动词）。

• choose

  General, everyday verb for picking one option among several; can take a direct object or 'to' + infinitive; neutral register, used in casual and formal contexts alike.

  通用的日常动词，表示在几个选项中挑选一个；可直接接宾语或接"to+动词原形"；语域中性，口语书面均可使用。

  She chose the blue dress instead of the red one for the party.

  她选了蓝色的裙子去参加派对，而不是红色的那件。

• opt 本词

  More formal and deliberate; usually describes choosing a course of action after weighing alternatives, almost always followed by 'to' or 'for'; common in written, official or decision-making contexts.

  语气更正式、更审慎；通常表示在权衡各种方案后选定某种行动方案，后面几乎总是接 to 或 for；常见于书面语、正式或决策类语境。

  After the accident, he opted for a safer, slower route to work.

  事故发生后，他选择了一条更安全但更慢的上班路线。

Choose and opt both mean to pick something. Choose is general and everyday, used for almost any decision, in speech or writing. Opt is more formal, describing a careful decision after weighing options, almost always followed by 'to' or 'for'.

两词都表示在若干选项中做出选择，但 opt 强调正式地"选定"某个方案或路线，常与 to 连用并带 for 短语；choose 更通用随意，可直接接名词或不定式，几乎适用于任何选择场合。这里不比较 choose 表示"愿意"这一层情态含义之外的用法。
