Compared meaning: quickly (adverb).

比较义项：迅速地（副词）。

• readily 本词

  Emphasizes willingness or ease rather than pure speed: doing something without hesitation or reluctance, often with verbs like agree, accept, admit.

  强调心甘情愿或毫不费力，而非单纯的速度：不带犹豫或抵触地做某事，常与agree、accept、admit等动词连用。

  She readily agreed to help with the moving boxes.

  她欣然同意帮忙搬那些箱子。

• promptly

  Emphasizes acting immediately and without delay, especially at an exact scheduled time; common with arrivals, replies, and deadlines.

  强调立刻行动、毫不拖延，尤其指准时在约定的时间做某事；常用于到达、回复、截止时间等场合。

  Please arrive promptly at nine o'clock for the interview.

  请务必在九点准时到达参加面试。

Readily stresses willingness or ease, not pure speed: doing something without hesitation, often with verbs like agree, accept, or admit. Promptly stresses acting immediately, without delay, especially at an exact time, as with arrivals, replies, or deadlines. This does not cover readily meaning easily available.

两者都可表示“很快地”，但readily强调心甘情愿、毫不犹豫，常修饰agree、accept、admit这类表态度的动词；promptly强调准时、不拖延，常用于按时到达或立刻处理请求。readily还有“容易地”（如readily available）这一常见义项，这里不作比较。
