Compared meaning: to throw something forcefully (verb).

比较义项：投掷、扔出（动词）。

• cast

  Cast suggests a light, controlled or purposeful throw, often with a fishing line, net, dice, or glance, and rarely implies anger or great physical effort.

  cast 表示轻巧、有目的的投掷动作，常用于甩钓鱼线、撒网、掷骰子或投出一瞥等，很少带有愤怒或用力的意味。

  She cast the fishing line far out into the calm lake.

  她把钓鱼线远远地甩到平静的湖面上。

• hurl 本词

  Hurl means to throw something with great force, often in anger or strong emotion, and frequently takes people or insults as its object.

  hurl 表示用很大的力气投掷，且常带有强烈情绪（如愤怒），宾语常是人或辱骂性的话语。

  He hurled the empty bottle across the room in fury.

  他愤怒地把空瓶子扔向房间的另一头。

• hurtle

  Hurtle usually describes an object or vehicle itself moving very fast and violently, rather than a person deliberately throwing something at a target.

  hurtle 通常描述物体或交通工具本身以极快、猛烈的方式移动，而不是指人把某物投向某个目标。

  The boulder hurtled down the mountainside, crushing everything in its path.

  那块巨石猛烈地冲下山坡，摧毁了沿途的一切。

Cast, hurl, and hurtle all mean to throw something forcefully, but differ in tone. Cast is light, as with a fishing line. Hurl means throwing hard, in anger. Hurtle stresses an object moving fast and violently. This does not cover cast meaning to assign roles.

这三个词都表示“把某物扔出去”，但用力程度和语气不同：cast 较轻巧、有目的，hurl 用力且常带情绪，hurtle 则强调物体本身极快、猛烈地移动。这里不比较 cast 的“分配角色”“投票”等其他义项，也不比较 hurtle 单纯描述人或车辆自身快速移动而不涉及投掷动作的用法。
