Lesson 40 Waves
1 . an ancient, exquisite, powerful message.一個源遠流長、高雅而有力的信息。
2 . Once waves have been generated,一旦波浪形成，
3 . These ocean waves are among the earth's most complicated natural phenomena,這些海浪屬於地球上最複雜的自然現象。
4 . awakening it to flow, to movement, to rhythm, to life.陽光使空氣開始流動，產生節奏，獲得生命。
5 . The undulating waves of the open sea are generated by three natural causes:海浪是由三個自然因素形成的：
6 . Although an ocean wave gives the impression of a wall of water moving in your direction,雖然，海浪給人的印象是一堵由水組成的牆向你壓過來，
7 . drawing the particle first towards the advancing wave,先把微粒拉向前移的海浪，
8 . a wave length (the horizontal distance between two wave crests),波長（兩個浪峰間的水平距離）
9 . then up into the wave, then forward with it and then然後推上波浪，隨著波浪移動，然後
10 . Rays from the sun excite and energize the atmosphere of the earth,太陽光刺激了地球的大氣層，並給予它能量；
11 . If the water was moving with the wave,如果水和浪一起移動的話，
12 . The basic features include a crest (the highest point of the wave),它們的基本特徵包括浪峰（波浪的最高點）
13 . the ocean and everything on it would be racing in to the shore with obviously catastrophic results.那麼大海和海裡所有的東西就會向岸邊疾湧而來，帶來明顯的災難性後果。
14 . a trough (the lowest point), a height (the vertical distance from the trough to the crest),波谷（最低點）、浪高（從波谷到浪峰的垂直距離）
15 . For a time it assumes a miraculous individuality that,一度它獲得非凡的個性，
16 . gravity is the force that drives them in a continual attempt to restore the ocean surface to a flat plain.地球引力是持續不斷企圖使海面復原為平面的力量。
17 . Waves are the children of the struggle between ocean and atmosphere.海浪是大海和空氣相鬥的產物。
18 . The wind then speaks the message of the sun to the sea and the sea transmits it on through waves.然後，風把太陽的信息帶給了大海，然後，風把太陽的信息帶給了大海。
19 . in actuality waves move through the water leaving the water about where it was.而實際上，浪從水中移過，而水則留在原處。
20 . the ongoing signatures of infinity.無限的一種不間斷的標誌。
21 . An ocean wave passing through deep water causes a particle on the surface to move in a roughly circular orbit,穿過深水的海浪使水面上的一個微粒按照一種近乎圓形的軌道移動，
22 . From both maturity to death, a wave is subject to the same laws as any other'living'thing.從成熟到消亡，波浪和其他任何活動中"的東西一樣，都受制於共同的法則。
23 . wind, earth movements or tremors, and the gravitational pull of the moon and the sun.風、地球的運動或震顫和月亮、太陽的引力。
24 . in the end, is reabsorbed into the great ocean of life.但最終又被重新融進生命的大洋。
25 . as the wave leaves the particles behind back to its starting point again.當波浪把微粒留在身後時又回到出發點。
26 . and a period (which is the time it takes a wave crest to travel one wave length).和週期（浪峰走過一個波長所需的時間）。
