Unit 1 Our living planetThe ocean deep 海洋深处We look upwards and wonder what lies beyond our planet. We send probes into the vastness of space to explore the unknown. We build space stations to advance our understanding of the universe. Our curiosity about outer space has remained unshakeable. Meanwhile, it is estimated that more than eighty per cent of the world's oceans are unexplored. So, if we want to find exciting new life forms as well as undiscovered and unusual geological formations, the ocean is where we should also be looking· Then why don't we dive to the bottom of a really deep ocean and take a long, close look beneath the waves?我们仰望天空，好奇在我们的星球之外有什么。

我们向浩瀚的太空发射空间探测器以探索未知世界。

我们建造空间站以增进对宇宙的了解。

我们对太空的好奇心一直以来从未动摇。

同时，据估算，世界上超过80%的海洋还未被探索。

因此，如果我们想找到令人激动的新生物以及未被发现的、不同寻常的地质构造，海洋也是我们应该去寻找的地方。

那么，我们为什么不潜到很深的海底，长时间地、仔细地观察海底呢?The first 200 metres of our dive takes us through what can be called the open ocean, where most visible light exists. Here lives much of the marine life we know about, such as dolphins, corals and seaweeds. Sinking below 200 mertes, we enter the twilight zone, where there is little sunlight and thus almost no plant life. Most of the fish living here are small filter feeders which swim up at night to feed in the nutrient-rich waters above .Also living in the twilight zone are hunters with telescopic, upward-pointing eyes that can easily spot a meal in the waters above. Consequently, the fish most likely to be eaten have evolved to have thin bodies so thar they arc less easily to be seen fr om below. However, once they are captured, the hunters’ backward-carving teeth prevent them from getting away. Evolution, it seems, helps both the hunter and the hunted in equal measure.我们下潜的头200米带我们穿过所谓的透光区，这里有大部分可见光。

我们所知的许多海洋生物，如海豚、珊瑚和海藻，生活在这一层。

下潜到200米以下，我们进入暮光区，这里没有阳光，因此几乎没有植物。

生活在此的大多数鱼类都是小型滤食性动物，它们在夜间向上游，到上面营养丰富的水域进食。

同样生活在暮光区的还有双眼凸起向上的猎食者，它们能轻易地发现上层水域中的食物。

结果，最有可能被吃掉的鱼已经进化成细长的身体，所以从下面不太容易看见它们。

然而，一旦它们被捕获，猎食者向后弯曲的牙齿让它们无法逃脱。

进化似乎在同等程度上帮助了猎人和猎物!Once past 1,000 metres, we have reached the deep ocean, where there is no light and temperatures drop just above freezing. The pressures are huge and can be more than 100 times the pressure of the Earth’s atmosphere. It is then surprising that many creatures can live in this extreme environment. They cannot rely solely on their eyesight to survive and have evolved fascinating characteristics. Indeed, many organisms in the deep ocean are blind. In order to obtain food and avoid being caught, they have to depend on other senses such as smell and their ability to detect slight changes in water pressure. Also, some fish have both male and female organs to increase the chances of reproduction, as fish are so scarce at these depths that it can be difficult for them to find a mate. The fish in the deep ocean are among the strangestcreatures on the Earth, many of which have yet to be properly studied.一旦超过1000米，我们就到达了深海区，这里没有光，温度降至略高于冰点。

压力巨大，可能是地球大气压力的100多倍。

令人惊奇的是，许多生物可以生活在这种极端的环境中。

它们仅仅依靠视觉无法生存，因而进化出神奇的生存特征。

事实上，深海中的许多生物都是看不见的。

为了获取食物和躲避被捕食，它们不得不依靠其他感官，如嗅觉，和感知水压微小变化的能力。

此外，一些鱼类同时拥有雄性和雌性器官，以增加繁殖的可能性，因为在这样的深度，鱼如此稀少，以至于找配偶对它们来说很难。

深海鱼类是地球上最奇怪的生物之一，其中许多还尚未被充分研究。

On reaching the ocean floor, we may see shrimps and other organisms around hydrothermal vents. These vents form in volcanically active areas, pouring mineral-rich fluids into the sea. Before the discovery of these creatures, it was thought that all life on the Earth obtained its energy from the sun. However, this discovery has revealed that life forms can obtain nutrients and energy from thermal sources. Knowing that life35 can exist in these extreme conditions has changed scientific opinion about the chances of there being life elsewhere in the universe. In addition to the vents and remarkable organisms, we cannot miss the Mariana Trench, located in the north-western part of the Pacific Ocean. Its deepest point, known as the Challenger Deep, is nearly 11 ,000 metres below sea level. You could place Mount Qomolangma in the Challenger Deep, and its top would still be more than 2,000 metres below the surface! While there is little life at such great depths, it is far from boring. Of the many strange geological formations to be found here are rock bridges which cross the Trench, some reaching a height of 2,500metres above the Challenger Deep.一到达海底，我们就可能在热液喷口周围看到虾和其他生物。

这些喷口形成于火山活动频繁的区域，喷涌出富含矿物质的流体进入海洋。

在发现这些生物之前，人们认为地球上的所有生命都是从太阳获得能量的。
