prepared

Compared meaning: ready for use or ready to act (adjective).

比较义项：准备好的，可供使用的（形容词）。

• ready

  Describes the immediate state of being available for use right now; it carries little sense of the effort behind it, and is common in casual, everyday contexts — for food, people, or a quick check before doing something.

  描述此刻“可供使用”的即时状态，不太强调背后付出的努力；常用于日常随意的语境中——比如食物、人，或者做某事前的一个简单确认。

  Dinner is ready — come and eat before it gets cold.

  晚饭好了——快来吃吧，别凉了。

• prepared 本词

  Emphasizes that deliberate preparation or planning happened beforehand; often paired with 'well' or 'fully' and typical of more serious or formal situations such as exams, interviews, or emergencies.

  强调事先经过有意的准备或计划；常与“well”或“fully”搭配使用，多见于考试、面试或紧急情况等更正式、更严肃的场合。

  He felt well prepared for the interview after researching the company for days.

  调查了这家公司好几天后，他觉得自己对这次面试已经准备得很充分了。

Both words mean ready to be used or to act. Ready stresses the present state of being available, and sounds casual. Prepared stresses earlier preparation or practice, and sounds more formal. Not compared: ready's senses 'willing' or 'quick', and the verb prepare, 'to cook'.

这两个词在这个义项上都表示“准备好了、可以使用或进行下一步”，语气接近，容易混淆；不同的是ready更强调此刻“可用”的状态，语气随意，prepared更强调事先经过准备或练习的过程，语气较正式。这里不比较ready表示“愿意的”“迅速的”等其他义项，也不比较prepared所对应的动词prepare“准备、烹制”等其他用法。
