What false impression does an ocean wave convey to the observer?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.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 troughto 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).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 be racing in to the shore with obviously catastrophic results.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.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.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.from World Magazine (BBC Enterprises)【New words and expressions 生词和短语】signature n. 签名，标记infinity n. 无穷ray n. 光线energize v. 给与...能量rhythm n. 节奏transmit v. 传送exquisite adj. 高雅的phenomena n. 现象crest n. 浪峰trough n. 波谷vertical adj. 垂直的horizontal adj. 水平的actuality n. 现实catastrophic adj. 大灾难的particle n. 微粒maturity n. 成熟undulate v. 波动，形成波浪tremor n. 震颤gravitational adj. 地心吸力的【课文注释】1.transmit vt.①传达例句：Gypsies frequently transmit recipes orally within the family.吉普赛人经常以口头形式把秘方世代相传。
