task

Compared meaning: a piece of work that needs to be done (noun).

比较义项：需要做的一项工作或任务（名词）。

• job

  Refers to a specific piece of work or duty someone is given; more general and informal than task, and unlike chore it need not be routine, small, or domestic — it can be any assignment, big or small.

  指某人被分配的某项具体工作或职责；比task更笼统、更口语化，也不像chore那样必须是常规性的、琐碎的或家务性的——它可以是任何大小的任务。

  Painting the fence turned out to be a bigger job than we thought.

  粉刷篱笆最后成了一件比我们预想中更大的job。

• chore

  A small, routine domestic task, often tedious or unwelcome, like cleaning or washing dishes; more specific and humbler than job or task, and usually repeated regularly rather than a one-time assignment.

  一项琐碎的、日常的家务，往往令人厌烦或不情愿去做，比如打扫卫生或洗碗；比job或task更具体、更不起眼，通常是要反复去做的，而不是一次性的任务。

  Washing the dishes is my least favorite chore at home.

  洗碗是我在家最不喜欢做的chore。

• task 本词

  A specific piece of work that must be completed, often with a clear goal or deadline; more formal and purposeful than job, and unlike chore it is not necessarily small or domestic.

  一项必须完成的具体工作，往往有明确的目标或截止日期；比job更正式、更有目的性，且不像chore那样必须是琐碎或家务性的。

  Finishing the report by Friday is my main task this week.

  在周五前完成报告是我这周的主要task。

Job, chore, and task all mean a piece of work to do, but they differ. Job is general and informal. Chore is a small, boring, routine household task, like cleaning. Task is more formal, with a clear goal or deadline. Not compared: job meaning employment.

这三个词在“需要做的一项工作”这一意义上很接近，但语气和场合不同：job更笼统随意，chore强调琐碎重复的家务，task更正式、目标或期限更明确。这里不比较job的“工作、职位”这一义项。
