Determined, bent, and resolute all mean firmly decided to do something. Determined is the common, neutral choice, used with "to" plus a verb. Bent appears only in "bent on," and sounds informal, often stubborn. Resolute is formal and literary, stressing steady character, not one goal.

这三个词都表示“下定决心要做某事”，但语气和用法不同：determined 最常用、语气中性，resolute 更正式、书面语，强调性格上持久不变的坚定，bent 通常只用于固定搭配“bent on doing sth”，且常带固执甚至负面的意味。这里不比较 bent 表示“弯曲的”这一常见义项，也不比较 determined 表示“（由计算或调查）确定的”这一义项。
