你感觉到气流从鼻孔出入吗？

Do you feel the airflow going through your nostrils?

如果你踢球的力量足够大，使得球表面的气流形成湍流，则阻力会很小，你很可能踢成高射炮。

If you kick the ball hard enough for the airflow over the surface to become turbulent, then the drag force remains small and the ball will really fly.

它能托着你就像托着下落的树叶强气流。

It can carry you like a strong current carries a fallen leaf.
