48. Earths Last Frontier[n.边疆]: The Sea. 　海洋，地球最后的待开发疆域 　　1. Weve all gone a little crazy about the outer space business, says Vice Admiral[海军中将] C.B. Momsen. The ocean is the place where we should be putting our efforts in order to provide for future generations. 1、“我们都对那些外太空的事情有些狂热，”海军上将C、B、Momsen说，“为了供养子孙后代，海洋才是我们应该投入努力的地方。” 单词：frontier=（待开发）疆域: generation＝一代2. Seventy-one percent of the earths surface is covered by water. An observer, looking at the earth from another planet, would be likely to call it Oceanus[n.海洋之神]. If all the continents and mountains were bulldozed[削平] flat, the earth would be covered by water more than 12,000 feet deep. 2、地球表面的百分之七十一被水覆盖。一个观测者从另一个行星看地球将可能称其为海洋之神。如果所有的大陆和山脉被推平，那么地球表面将被一层超过12000英尺深的水所覆盖。 单词：bulldoze＝； 3. Sea and air are divided by a viscous[a.粘性的] curtain; beneath the curtain is an element weighing 800 times as much as air, utterly[adv.完全地] dark a few fathoms[(fathom):英寻] down, and with pressures[(pressure):n.压力] that would pulp[n.果肉] a man at 3,000 feet. Yet we know that many animals live in the deeps at pressures of 15,000 pounds per square inch. 3、海洋和空气被一种粘性的“帘布”分开，“帘布”之下是一种比空气重800倍的成分，向下几英嚼完全黑暗，在3000英尺深处的压力会把人压成酱。然而，我们知道很多动物生活在每英寸15000磅压力的深处。 单词：viscous＝粘性的； as much as＝差不多； utterly=完全地； pressure＝压力；4. As a life environment, the sea is a kind of land turned upside down. The sunlit[a.阳光照射的] pastures[(pasture):n.牧场] are at the top, where the water is saturated[浸透] with tiny[adj.微小的] drifting[漂浮的] vegetables, phytoplankton[浮游植物], and equally minute animals, zooplankton[浮游动物]. The athletic[adj.运动的] animals come up to graze[吃草] in this fertile[a.肥沃的] prairie[n.大草原] and become links in extensive[a.广阔的] food chains, formed roughly[大致上，粗略地] along the lines[台词] suggested by Shakespeare: 4、作为一个生命环境，海洋如同一块倒转过来的陆地。阳光普照的牧场在上面，这里的海水中充满着微小的漂浮植物，也就是浮游植物，以及同样微小的动物、即浮游动物。运动的动物从下层海水中游上来，到这块肥沃的“牧场”上觅食，构成了广阔的食物链中的环节。这些大致如同莎士比亚的剧本台词中所说： 单词：sunlit＝照射的； pasture＝牧场； saturate＝；tiny＝微小的； drifting＝漂浮； athletic＝运动的； graze＝吃草 fertile＝肥沃的 extensive
