　　正步是在正式的军事阅兵或者其他庆典场合采用的特殊前进步伐。阅兵行进时，全体士兵统一将腿交替抬高离地，同时保持双腿挺直、不弯曲。

　　Originating in Prussian military drill in the mid-18th century, the step was called the Stechschritt(literally, "piercing step") or Stechmarsch. Nearly fifty countries maintain the tradition.

　　这种步伐最早源于18世纪中期普鲁士的军事训练，当时被叫做Stechschritt(字面意思为“穿透式步伐”)。目前，仍有近50个国家还在使用这个步伐。

　　"Goose step" is a pejorative term in English, indicative of authoritarian and militaristic regimes. Itoriginally referred to a British military drill, in which one leg at a time was swung back and forthwithout bending the knee. Apparently standing on only one leg reminded soldiers of how geeseoften stand.

　　英文中对于正步的说法goose step其实是个有贬损意味的表达，暗指专制和军国主义统治。Goose step一开始用于指代英国军事训练中，两腿交替前后摆动而保持不弯曲的步伐，而士兵单腿站立的时候，样子很像一直鹅。
