[02:06.75]THE SEA

[02:08.17]海洋

[02:09.59]Seen from space,the earth looks blue.

[02:12.52]从太空望去,地球看上去是蓝色的.

[02:15.44]This is because two thirds of the earth's surface

[02:21.51]is made up of vast 5 oceans.

[02:23.84]这是因为地球表面三分之二是由广阔的海洋组成的.

[02:26.18]Little of the earth's solid 6 surface has been seen by humans,

[02:29.60]人类只看到地球固体表面的一小部分,

[02:33.03]as much of it lies below the sea.

[02:35.45]因为大部分地表处于海洋下面.

[02:37.88]The oceans of the world are salty.

[02:40.37]世界上的海洋都是咸的.

[02:42.85]Most of the oceans contain 35 parts of salt per thousand parts of water.

[02:47.67]大多数的海洋每1000份海水里含有35份盐.

[02:52.49]That is 3.5% by weight.

[02:55.57]按重量计算为3.5%.

[02:58.65]There are 11 other minerals that make up the salt water of the oceans.

[03:02.43]另外还有11种矿物质,组成了海洋的盐水.

[03:06.20]How does sea water stay clean?

[03:08.54]那么,海水怎样保持清洁?

[03:10.88]The answer is that seaweeds produce various chemicals

[03:14.51]答案的海草可以释放各种各样的化学物质

[03:18.14]that help keep the sea water clean.

[03:20.32]这些化学物质可以帮助海水保持清洁.

[03:22.50]The Mediterranean 7 is more than 3,700 km 8 long,

[03:26.18]地中海长3700千米,

[03:29.87]and is 1,800km wide at its widest point.

[03:33.55]最宽有1800千米.

[03:37.23]The surface water is warm,and in summer

[03:40.11]它的表面水是暖和的,在夏天

[03:42.98]can reach up to 25 degrees centigrade 9 or even 29 degrees centigrade.

[03:47.46]它可以达到25摄氏度,甚至是29摄氏度.

[03:51.94]Because the weather is very hot,the sea loses a lot of water to the air,

[03:55.91]因为那里的天气非常热,大海水被蒸发了到了天空,

[03:59.88]so there are between 37 and 39 parts of salt per thousand.

[04:03.97]所以那里一千份海水中就含有37到39份盐.

[04:08.06]It takes 80 years ,

[04:12.00]for Mediterranean water to be changed with Atlantic water

[04:15.03]它需要用80年的时间才能跟大西洋的水交换一次

[04:18.06]as there is only one narrow entrance

[04:22.82]where the Mediterranean meets the Atlantic.

[04:25.20]因为地中海和大西洋的汇合处只有一个狭窄的入口.

[04:27.57]Hot parts of theworld where the sea is not deep have coral 10 beds.

[04:31.35]世界上热的地方,在海不深处有珊瑚.

[04:35.12]Coral is not a plant

[04:37.05]珊瑚不是植物.

[04:38.99]but a variety of animal life of different shapes and bright colours.

[04:42.67]而是形状不同,色彩斑斓的动物变体.

[04:46.35]Coral needs certain conditions in order to live.

[04:49.03]珊瑚生存需要一定的条件.

[04:51.71]The water temperature must not fall below 20 degrees centigrade

[04:55.13]水的温度不可以低于20摄氏度,

[04:58.55]and there must be plenty of light,

[05:00.63]和充足的阳光,

[05:02.71]so corals 11 are found in water with a depth 12 of less than 60 metres.

[05:06.59]所以在水深不超过60米的地方常驻可找到珊瑚.

[05:10.47]Also,the water must be very clear.

[05:13.04]海水也必需得是清洁的.

[05:15.61]Water that is cloudy or dirty will kill the coral.

[05:18.69]污浊的水会使珊瑚死亡.

[05:21.78]If construction work is going on,for example to build a new port,

[05:25.46]如果进行施工,比如说是建一个新的港口,

[05:29.14]or if there is any pollution,this will kill the coral.

[05:32.32]或是海水有任何污染,这都会杀死珊瑚.

[05:35.49]Besides,you will not find coral near the mouths of rivers either

[05:39.17]除此之外,在江河的入海也找不到珊瑚.

[05:42.86]because the river water has too much soil in it or because it is polluted 13.

[05:46.93]因为河水有太多的土壤,或者它被污染.

[05:51.01]The longest coral bed in the world

[05:53.35]世界上最长的珊瑚

[05:55.68]is one which lies off the northeast coast of Australia.

[05:58.80]在澳大利亚东北沿海上.

[06:01.93]It is 2,010 kilometres long.

[06:04.90]它长2010千米.

[06:12.43]SALT LAKES OF THE WORLD

[06:14.26]世界上的咸水湖

[06:16.08]The most famous salt lake in the world is the Dead Sea,in the Middle East.

[06:19.57]世界上最出名的盐海是死海,它在中东地区.

[06:23.06]Water is lost into the air because of the heat of the sun,

[06:25.93]因为酷热水蒸发到场天空中,

[06:28.81]and the salt stays in the lake.

[06:30.62]而盐却留在了湖里.

[06:32.44]It is also very lowlying,at around 395 metres below sea level.

[06:36.60]死海地势很低,约低于海平面395米.

[06:40.77]However,it is not the saltiest lake in the world.

[06:43.20]然而,它不是世界上最咸的湖.

[06:45.63]The Great Salt Lake in the USA,

[06:47.76]美国大盐湖的水还要咸一些,

[06:49.89]with 270 parts of salt per thousand,is even saltier.

[06:53.37]因为每千份水里就含有270份盐.甚至更高.

[06:56.86]The water of the Dead Sea contains about 250 parts of salt

[07:00.40]死海的海水含有盐大约为250

[07:03.94]to every thousand parts of water,or 25% by weight.

[07:07.42]每一千份,或按重量计是25%

[07:10.89]It is so salty that it is difficult to swim or dive,

[07:13.78]湖水太咸了很难游泳或潜水,

[07:16.66]as your body floats on the surface.

[07:18.64]因为你的身体会浮在水面上.

[07:20.61]What has made this lake so salty?

[07:22.64]是什么使得这湖含盐量如此的高?

[07:24.68]The minerals are partly supplied by hundreds of natural springs

[07:27.86]是各种矿物质.它们部分来自众多的流入死海的天然泉水,

[07:31.03]which flow into the Dead Sea,and partly by the River Jordan.

[07:34.22]还有一部分是来自约旦河.

[07:37.40]It is called the Dead Sea

[07:40.96]because very few things can live in such salty water.

[07:43.92]它被叫为死海是因为很少有生物能在含盐量如此高的水里生存.

[07:46.89]There is very little rain here,merely 66mm in a year on average.

[07:50.52]那里几乎不下雨,每年平均只有66毫米降雨量.

[07:54.15]The minerals stay in the lake,

[07:57.60]because there is no river flowing out of the lake.

[07:59.97]那些矿物质留在湖里,是因为没有河从死海中流出.

[08:14.81]LIFE IN THE OCEANS

[08:16.59]海洋中的生物

[08:18.36]In the oceans around Antarctica 14 the temperature of the water is freezing,

[08:22.14]在南极洲周围的海洋中,水温很低,

[08:25.91]always below zero.

[08:27.79]总是在零度以下.

[08:29.68]Fish can live in these temperatures

[08:31.80]鱼之所以能生活在这样温度下

[08:33.93]only because their blood contains a particular chemical.

[08:36.87]只是因为它们的血液中有一种特别的化学物质.

[08:39.81]In these oceans live huge numbers of a small fish just 5 cm long.

[08:43.83]在这些海洋中生活着大群众路线大群只有五厘米长的小鱼.

[08:47.86]These fish swim together,

[08:49.78]这些鱼成群结队地在水中游,

[08:51.70]often in a group that may be 4.5 metres thick and hundreds of metres long.

[08:56.02]通常一个鱼群可能有4.5米厚,几百米长.

[09:00.34]There may be 63,000 fish per cubic 15 metre.

[09:03.53]每立方米大约有63000条鱼.

[09:06.72]These fish provide the main food for whales.

[09:09.34]这些鱼成了望鲸鱼的主要食物.

[09:11.97]A whale may eat a ton of them at a time,and may enjoy four meals a day.

[09:16.45]一头鲸鱼一次可以吃掉一吨这种鱼,并且一天可能吃四次.

[09:20.93]The squid 16 lives in the dark at a great depth at the bottom of the ocean.

[09:25.11]鱿鱼住在海底很深很暗的地方.

[09:29.29]It can grow to a length of 15 metres.

[09:32.07]它可以长到15米长.

[09:34.85]It is eaten by a type of whale called the sperm 17 whale,

[09:37.93]有一种叫巨头鲸的鲸鱼

[09:41.02]which is over 18 metres long.

[09:43.29]长度超过18米.

[09:45.56]The sperm whale does not feed on small fish like other whales.

[09:48.73]和其它鲸鱼不一样,巨头鲸是不以小鱼为食的.

[09:51.91]Instead it has teeth and feeds on squid.

[09:57.24]It can dive to a depth of 1,000 metres.

[10:00.22]相反,它有牙齿,就吃鱿鱼.它还可以潜入水下1000米不深入.

[10:03.19]On one ship which had equipment for measuring the depth of the water,

[10:06.73]在一艘装有测量水深设备有船上,

[10:10.27]the captain noticed a sperm whale diving to a depth of nearly 2,250 metres.

[10:15.25]船长发现一头巨头鱼潜入到将近2250米深处.

[10:20.23]How does the sperm whale manage to do this?

[10:22.50]巨头鲸为何能潜到这样深呢?

[10:24.77]When it dives,its heart slows to half its normal speed.

[10:28.10]它潜水时,它的心跳速度就减慢到正常心速的一半.

[10:31.43]By doing this the animal can hold its breath for a longer time.

[10:34.97]通过减慢心速,这种动物就能在较长的时间内屏住气.

[10:38.51]The head contains a lot of oil,and this is probably cooled at the same time.

[10:42.78]它的头部有很多油,在潜水时这种油很可能被冷却.

[10:47.05]At the bottom of the ocean it is completely 18 dark.

[10:49.63]在海底是完全黑暗无光的.

[10:52.20]The sperm whale therefore has to look for the squid using sound waves.

[10:56.13]因此巨头鲸就只得利用声波来找鱿鱼
