CNN News:马来西亚失踪航班MH370搜寻工作进入新阶段

More is known about the surface of the Moon and Mars than the bottom of the Earth`s oceans. That`s adding to the challenge of finding a missing passenger plane.

关于月球和火星的表面比地球上的海洋了解还要多，这就加大了寻找失踪客机的难度。

First up this Wednesday on CNN STUDENT NEWS, the search for Malaysia Airlines Flight 370. It`s entering a new phase, the jet and its 239 passengers and crew members disappeared in early March. Officials believe it crashed in the southern Indian Ocean. The primary search area is about

首先，这是本周三的CNN学生新闻，今天来说一说关于寻找失踪的MH370客机的调查。目前调查进入了一个新阶段，该客机搭载着239名乘客和工作人员在三月早些时候失踪不见。官方认为该飞机坠入了南印度洋。

the size of West Virginia. No trace of the jet has been found. Part of the reason, we know so little about the ocean floor. Just five percent of it has been mapped. And one expert says we`ve only seen one percent. Why? For one thing, pressure. Engineers have trouble constructing machines that

最主要的搜索范围是在弗吉尼亚西岸，但是没有找到任何关于飞机的痕迹。其中部分原因是我们对海底还不是很了解，只有百分之五的海底地形被绘制成了地图。有位专家称，我们只看见了海底的百分之一的地方。为什么这样说呢?其中一个原因就是压力。工程师在建造可以足以承受海底压力机器方面面临科技上的难题。

can stand the weight of the water above them. But new data can help explore the ocean floor.

但是最新的数据显示可以帮助我们探索海底世界。

All through the thundering waves of winter, the ships have pressed on across the Indian Ocean, pulsing out sonar signals. And this is what they have to show for it. The most detailed map ever of the seabed in this area, 16,000 square miles covered with crumbling underwater volcanoes, winding valleys, plunging canyons and just maybe the solution to a mystery. The new map is not fine enough to show wreckage, but it is a wealth of information to guide under water search vessels.

尽管冬天海浪翻滚，船只依旧行驶在印度洋上探测声呐信号发出的脉冲声波。这也是海底地形呈现方式。这个领域最详细的地图大约涵盖16,000平方英里面积，包括海底火山，蜿蜒的山谷，使这片海底世界成为未知的秘密。最新更新的地图并没有清晰显示出残骸的存在，但是对于水下搜索船舶来讲仍然是非常有帮助的工具。

Tom, there makes a great deal of difference, because they`ll be able to hold a tighter path right above the ocean floor knowing what`s coming ahead of time, so that they can go a little bit faster and get a lot more done in the less time.

汤姆，这是一个很大的不同，因为他们可能掌握海底动态采取快速行动节省更多时间。

Before the search broke off earlier this year, much hope was pinned on the Bluefin underwater search robot. It came up empty, but now, with the new map, a much broader search with toad sonar erase is beginning.

在今年早些时候搜索工作一开始，希望多被寄予在了蓝鳍身上，这是一种水下搜索机器。但是没有取得任何进展，不过现在，有了最新地图的帮助，会开始进行更广泛的声呐搜索行动。

Australian authorities remain convinced this arch is the right place to look, saying recent refinement to the analysis of satellite data about the plane`s flight path has given greater certainty about when the aircraft turned south into the Indian Ocean. And that gives them a better sense of where it ran out of fuel, most likely south of this submerged mountains called Broken Ridge. But .

澳大利亚当局仍然坚信这个拱门是寻找失踪飞机的正确地点，称最近改进飞机的卫星数据分析了飞机航线，为飞机曾经掉头南下坠入印度洋提供了更明确的可能性。这同时也为飞机燃油耗尽提供了真实性，很可能南部这个淹没的山体可能就是失踪的飞机，成为破碎的背脊。

We have to be very cautious about over-predicting or over- confidence in those predictions that you make or you`ll end up exactly where you thought you would, but it may not be the right place.

但是我们对这些大胆猜测和大胆预测必须谨慎进行，在这些猜测里你可能非常认同你的观点，但到最后这些观点未必都是正确的。

Don`t look for people scanning the surface for debris, those days are over. Now, it is all about looking in some places nearly four miles beneath the waves, and once again, hoping for a break.

不要再进行碎片扫描，这个阶段已经过去了，现在需要做的是在这接近4英里的区域里，再一次进行搜索，希望有新发现。

The search is scheduled to last for about a year, and if they find the plane during that time, of course, it will be a huge step, but a big mystery still remains, whatever caused this plane to go down.

搜索计划进行大约一年时间，如果在这段时间内有了最新发现，毫无疑问将会是重大新闻，但也会是重大谜团。无论什么原因致使飞机出现在了这片区域。
