高中英语人教版高二下课文03

[13:07.12]In fact,the zone is so dark and empty
[13:12.76]that scientists named this zone after the Greek word for"no bottom".
[13:19.01]There is not much life to be found
[13:23.24]in this cold and unpleasant part of the ocean,
[13:27.78]but some small creatures still manage to survive here
[13:33.35]despite the high water pressure.
[13:37.19]Few of the animals inthe ocean can dive this deep.
[13:42.23]One exception is the sperm whale,
[13:46.78]which slows its heartbeat in order to reach this zone as it hunts for food.
[13:53.85]The very deepest part of the ocean if found 2,000 metres further down.
[14:00.93]At this depth,the water pressure is extremely high
[14:06.68]and life is very difficult for the few creatures that live here.
[14:12.45]Compared to the other zones,this one has very little life.
[14:18.62]Since there is no light here,
[14:22.38]some of the animals do not have eyes.
[14:27.84]When scientists explored the very deepest parts of the ocean,
[14:33.40]they did not expect to find any life at all.
[14:38.58]However,it turned out that there are creatures
[14:43.54]that can live even in habitats as far down as 10,000 metres.
[14:51.12]They usually survive by living close to deep sea vents,
[14:57.46]"chimneys"that send out gases from within the earth.
[15:03.11]Unlike all other living things on the earth,
[15:07.76]which get their energy from the sun,
[15:11.73]the creatures that live here use chemicals from the vents to stay alive.
[15:18.99]Next time you look at the ocean from the beach or on a map,
[15:24.13]remember that what you are seeing is only the surface
[15:29.59]-Only the beginning of the large and caried adventure that is ocean.
