" Restrictions, such as not washing cars at home, and no power washing houses."

“限制措施，比如不在家洗车，不用电力清洗房子。”

So we can measure how high the wave is at every given instant and how fast the wave is moving across through the houses washing away the houses and across the street.

所以我们可以测量海浪在每个给定的时刻有多高，以及浪潮穿过房屋、冲走房屋、穿过街道的速度有多快。
