2019年高中英语 Unit 3 Under the sea教案 新人教版选修7【美文阅读】广袤无垠的海洋，孕育了无数生命传奇，以其独有的神秘吸引着人类对其进行不懈的探索。为此，海洋科学家通常把海洋分为五个区域。现在就让我们一起了解一下吧！The earths oceans can reach depths of up to 11,000 metres.That is deep enough to cover Mt.Qomolangma！The oceans are incredibly(不可思议的)large and contain several different habitats.To make it easier to describe the various parts of the oceans，marine(海上的)scientists usually divide the oceans into five zones.Each zone is different mainly as a result of how much sunlight reaches it.Most of the life in the ocean can be found in the first zone，which begins at the surface and goes down about 200 metres.Because there is sunlight at this level，plants are able to grow.Marine animals such as dolphins，sharks，sea turtles and sea lions，and of course a variety of fish，live in the sunlit(阳光普照的)part of the ocean.It is difficult to hide from other animals in this area.The second zone starts at 200 metres and goes down to about 1,000 metres.Some sunlight can reach this level，but it is not enough for plants to grow.Because this zone is relatively dark，many of the creatures that live here are able to make light with their body.The light from these animals makes the water look like a sky with moving stars in it.The third zone of the ocean is dark.This place，about 3,000 metres deep，may not seem a likely habitat，but there are more creatures here than one might think.Most of the animals that live here are black or red because of the lack of light.Below 4,000 metres，the temperature is near freezing and there is no light at all.In fact，the zone is so dark and empty that scientists named this zone after the Greek word for “no bottom”There is not much life to be found in this cold and unpleasant part of the ocean，but some small creatures still manage to survive here despite the high water pressure.The very deepest part of the ocean is found 2,000 metres further down.At this depth，the water pressure is extremely high and life is very difficult for the few creatures that live herepared to the other zones，this one has very little life.Since there is no light here，some of the animals do not have eyes.Next time you look at the ocean from the beach or on a map，remember that what you are seeing is only the surfaceonly the beginning of the large and varied adventure.【诱思导学】1Why do these animals living in the second zone make the water look like a sky with moving stars in it?_2Do you think it is possible for some creatures that live in the very deepest part of the ocean to see each other?_【答案】1.Because many of them are able to make light with their body.2.No.Because there is no light here and some of the animals have no eyes.Period
