Section 64 Under the Sea六十四　海底世界

1.Perhaps the most unexplored area on this planet is under the sea. 在这颗星球上，尚未被大规模开发过的地区也许只有海底。

2.Today there are large areas which we have never been to. 至今，仍有许多我们从未到过的地方。

3.They are too deep for us to examine in detail. 他们太深了，我们无法探个究竟。

4.Although we do have commercial exploration of the sea bed, it is still unknown. 尽管我们对海床做过商业性的探索，它仍然是个未知数。

5.The marine life of the upper and middle waters are fairly well recorded. 上层和中层水面的海洋生物几乎没有完整地被记录过。

6.However, the deep sea environment can still reveal many secrets. 然而，深海的环境也许能揭示更多的秘密。

7.To explore these areas is difficult because of the great pressure deep down. 由于海底的巨大压力，要开发这些地方有困难。

8.We can not build the right machines that can sustain life at the very bottom. 我们还无法制造出一台能够在深海维持生活的机器。

9.When we are able to do so, we will discover a whole new world of marine matter. 如果这能实现，我们将发现一个全新的海洋世界。

10.The sea is a source of food for many people and a source of income. 对于许多人来说，海洋是他们食物和收入的来源。

11.We have deep sea villages drilling for oil and gas under the sea bed. 我们有深海“村庄”，用于开发海底石油和天然气。

12.The natural resources of the deep sea are still relatively untapped. 大海深处的自然资源仍然尚未触及。

13.It could be that there lies some of the solutions to our resources problems. 那里也许潜藏我们能源问题的解决之道。

14.Having learned from our mistakes towards the environment on the surface of the earth, we will be more cautious when utilizing the world below it. 从地球表面开发所犯的错误中吸取教训，我们对海底的开发应该谨慎。

15.Science will reveal the secrets of deep sea one day, and it will be very exciting to learn what is there. 科学家们会发现深海的秘密，也许有一天，会给我们一个惊喜。
