done

Compared meaning: finished or ended (adjective).

比较义项：结束的，完成的（形容词）。

• through

  Used only after a linking verb, never before a noun; informal, often paired with "with" to show someone has personally stopped dealing with a task or relationship.

  只能用在系动词之后，不能放在名词前；口语化，常与“with”搭配，表示某人不再处理某项任务或关系。

  The mechanic said he was finally through with the old car's endless repairs.

  技师说他终于不再理会这辆旧车没完没了的维修问题了。

• over

  Describes an event, situation or period ending at a point in time, such as a meeting, game or relationship; rarely combined with "with" and not used for a finished personal task.

  描述某个事件、情况或阶段在某一时刻结束，例如会议、比赛或恋爱关系；很少与“with”连用，也不用来表示个人任务已经完成。

  By nine o'clock the meeting was over and everyone went home.

  到九点的时候，会议结束了，大家都回家了。

• complete

  More formal and neutral; describes a set, project or structure that has every part it needs, with nothing missing, and can stand before or after a noun.

  更正式、更中性；用来描述某个整体、项目或结构具备了所需的全部部分，一无所缺，可放在名词前或名词后使用。

  The puzzle was complete once she placed the final piece in position.

  拼图在她放上最后一块之后就完整了。

• done 本词

  The most common everyday word for "finished"; used mainly after "be", often with "with" for tasks, and can also describe food that has finished cooking.

  是表示“完成”最常用、最口语化的词；主要用在系动词之后，常与“with”连用表示任务完成，也可以用来描述食物已经煮熟。

  Are you done with your homework, or do you still have more to finish?

  你的作业做完了吗，还是还有一些没写完？

Through, over, complete and done all mean 'finished'. Through and done are informal, often with 'with', for a stopped task. Over means an event or period has ended. Complete is more formal: nothing is missing. Not compared: through/over as prepositions, complete as a verb.

这四个词都可以表示“结束了、完成了”，是学习者容易混淆的近义词，但语气和常见搭配不同：through和done多用于口语，常与“with”连用表示不再处理某事；over多指某个事件或阶段结束；complete更正式，强调整体完整无缺。这里不比较through作介词表示“穿过”、over作介词表示“在…上方，越过”，以及complete作动词表示“完成”的用法。

Compared meaning: cooked and ready to eat (adjective).

比较义项：（食物）做熟的、可以吃了（形容词）。

• done 本词

  A general result word: says the food has finished cooking and is ready to eat, without saying how it was cooked (boiled, fried, roasted, etc.). Very common in casual speech, often as 'be done'.

  这是一个表示结果的通用词：只说明食物已经做熟、可以吃了，并不说明是用什么方法做的（煮、炸、烤等）。在口语中很常见，常用 be done 这种结构。

  Check the chicken with a thermometer to make sure it's done before you serve it.

  用温度计检查一下鸡肉，确保端上桌之前它已经熟了。

• roast

  Describes food cooked slowly in an oven or over a fire, usually a whole piece of meat or vegetables; it names the cooking method itself, not just the result. Typically used before a noun, like 'roast chicken'.

  指用烤箱或明火慢慢烤熟的食物，通常是整块的肉或蔬菜；它说明的是烹饪方法本身，而不只是熟了这个结果。通常放在名词前使用，比如 roast chicken（烤鸡）。

  On Sundays my family usually has roast chicken with potatoes.

  我家周日通常吃烤鸡配土豆。

Done and roast both describe cooked food. Done says food has finished cooking, without saying how. Roast means cooked in an oven or fire, often a whole piece of meat, usually before a noun. Done can also mean 'finished a task'; not compared here.

这两个词都表示食物已经加热到可以食用的状态，但 roast 特指用烤箱或明火烘烤这种烹饪方式，而 done 只说明“熟了”这个结果，不说明是怎么做熟的。这里不比较 done 的其他常见义项，例如“完成了（某项任务）”。
