It has been 50 years since the Trieste submersible made the only descent of humans into the deepest place in the ocean, the Mariana Trench. In the coming decades, we need to look again into the depths of our own piece of the solar system. We’ve explored only about 5 percent of the ocean. It’s maddening that we know so little about what the seafloor looked like at the site of the Deepwater Horizon spill before the oil began to leak. It’s only a mile underwater! For us to have better maps of the moon, Mars, and Jupiter than our own ocean floor is baffling.
The natural world, especially the ocean, keeps us alive. More than half of all of the oxygen in our atmosphere is generated by organisms in the sea. We need to understand the systems that sustain us. Underwater monitoring and remote-operated vehicles such as the Nereus are improving, but those alone are not enough. The human brain and senses, the ability to wonder and to confront the unexpected—you can’t get that out of a machine.
Japan, Russia, and France(but not the United States)have deep-diving submersibles that can carry humans down to 5,000 meters and beyond. There is currently no manned sub with the capacity to go to full ocean depth, 11,000 meters. The technology already exists; We could build a pair of three-person deep-diving subs for less than $ 50 million. James Cameron is well on the way to having a one-person sub for that depth.
Therefore, we need to pull up our socks and realize that we still have a chance to prevent the loss of all sharks, coral reefs, and rain forests and to stabilize our atmosphere and the acidification of our oceans. Living in undersea laboratories nine times, I’ve had the opportunity to get to know individual fish and their quirky habits. I’ve met humpback whales, sea turtles, giant groupers, and an egg-bearing octopus I encountered in a one-person sub—creatures who had never seen a human before.
Many animals are struggling through this time of perilous change. But we alone can understand what is happening and what to do about it. Seeing the sharp declines in parts of the ocean I have come to know and love reminds me that as we look into new ways to protect our planet from climate change, we need to look again at the natural machinery that already works, that developed over four and a half billion years, and do everything we can to restore its functions. It is the engine that will power us to the future.
What can we infer from Paragraph 1?
选项
A、Ocean exploration has made little progress so far.
B、Deep parts of the solar system should be studied.
C、More work is needed for a better use of marine resources.
D、Submersibles can hardly reach as deep as one mile underwater.
答案
C
解析
推断题。综合本段内容,作者提到远洋公司漏油事件,指出在事故发生之前,人们对出事地点的海底情况知之甚少,后文又提出我们对自己星球的大洋洋底应该有更好的了解。将这两件事联系起来,可见作者认为要想更好、更安全地利用海洋资源,还需要更多的努力。故[C]是正确推断。选项[A]属于过度推断,作者虽然提到50年间没有再进行载人潜海,但也不能据此说海洋探索没有什么进展。[B]曲解了第二句话,作者所说的“our own piece of the solar system”是指地球,而不是太阳系,故[B]也错误。作者在讲述完远洋公司事件后感叹说“那只是水下一英里”,这里并不是说技术不能达到,而是强调人们没有重视,故[D]“潜艇不能下潜到一英里以下”是错误的。
