Cause, campaign, and crusade can all mean organized effort toward a goal. Cause names the goal or ideal people support, not the actions taken. Campaign is a planned set of actions used in business or politics. Crusade suggests a passionate effort against a wrong.

这三个词都可以指为达成某个目标而进行的努力或运动，但侧重不同：cause 强调人们所支持的目标或理念本身，campaign 强调有计划、分阶段的行动（常用于商业、政治或军事），crusade 则强调带有强烈道德热情的改革运动。这里不比较 cause 表示原因的用法（如 the cause of the fire），也不比较 crusade 指历史上十字军东征的原始含义。
