第1段
Waves are the children of the struggle between ocean and atmosphere, the ongoing signatures of infinity. Rays from the sun excite and energize the atmosphere of the earth, awakening it to flow, to movement, to rhythm, to life. The wind then speaks the message of the sun to the sea and the sea transmits it on through waves—an ancient, exquisite, powerful message.
大海和空气搏击诞生了海浪——标识着无限，而又持续不断。太阳光刺激了地球的大气层，并给予它能量；阳光使空气开始流动，进而流通，产生节奏，获得生命。 然后，风把太阳的信息带给了大海，海洋用波浪的形式传递这个信息—— 一条古老、精妙而有力的信息。
第2段
These ocean waves are among the earth's most complicated natural phenomena. The basic features include a crest the highest point of the wave, a trough the lowest point, a height the vertical distance from the trough to the crest, a wave length the horizontal distance between two wave crests, and a period which is the time it takes a wave crest to travel one wave length.
这些海浪属于地球上最复杂的自然现象。它们的基本特征包括波峰 （波浪的最高点）、波谷（最低点）、波高 （从波谷到波峰的垂直距离）、波长（两个波峰间的水平距离）和波周期（波峰走过一个波长所需的时间）。
第3段
Although an ocean wave gives the impression of a wall of water moving in your direction, in actuality waves move through the water leaving the water about where it was. If the water was moving with the wave, the ocean and everything on it would
虽然，海浪给人的印象是一堵由水组成的墙向你涌过来，可实际上，浪穿水而过，水仍留在原处。要是波浪携水而动，那么大海和海里所有的一切
第4段
be racing in to the shore with obviously catastrophic results.
都将竞相涌向海岸，并造成显著的灾难性后果。
第5段
An ocean wave passing through deep water causes a particle on the surface to move in a roughly circular orbit, drawing the particle first towards the advancing wave, then up into the wave, then forward with it and then—as the wave leaves the particles behind—back to its starting point again.
海浪穿过深水，只会让海面的水质点按照近乎圆形的方式绕个圈。水质点被前移的海浪拉向自己，然后向上汇入海浪，接着随着海浪前行，水质点被抛在身后，回到原点。
第6段
From both maturity to death, a wave is subject to the same laws as any other "living" thing. For a time it assumes a miraculous individuality that, in the end, is reabsorbed into the great ocean of life.
从成熟到消亡，海浪和其他任何“活动中”的东西一样，都受制于大自然的规律。它一度呈现出令人惊叹的个性，但最终还是再次被卷入生命的大洋。
第7段
The undulating waves of the open sea are generated by three natural causes: wind, earth movements or tremors, and the gravitational pull of the moon and the sun. Once waves have been generated, gravity is the force that drives them in a continual attempt to restore the ocean surface to a flat plain.
风、地球的运动或震颤，以及月球和太阳的引力，这三个自然因素导致了远洋上海浪的起伏。一旦海浪形成，地球引力是持续不断企图让海面归于平面的力量。
