托福TPO/Official 14 Task 4口语原文独立/综合口语题目答案解析-范文音频翻译-新东方托福官方网校手机版

旁白：听一段海洋生物课上的一节课。

Narrator: Listen to part of a lecture in a Marine Biology class.

教授：很多植物和动物生活在海洋的表面，

Professor: A lot of plants and animals live near the surface of the ocean,

这意味着在地表附近有很多食物，因为有很多植物和动物可以吃，

and that means there's a lot of food near the surface, because there are lots of plants and animals to eat,

但是如果你深入到海洋的最深处，

but if you go down to the deepest parts of the ocean,

因此，生活在这些深海的生物已经进化出了特殊的适应能力来帮助它们在这个环境中生存，

So organisms that lived down at these great depths have developed special adaptations to help them survive in this environment,

例如，许多深海生物的身体特征使它们能够捕食比自己更大的猎物。

For example, many deep-sea organisms have body features that enable them to eat prey that are larger than themselves.

有一种鳗鱼有巨大的嘴巴和大胃，有能力扩张。

There's a species of eel that has an enormous mouth and a large stomach that's capable of expanding.

这些不寻常的特征使得这条鳗鱼吃的猎物比它自己大。

And these unusual features allow this eel to eat prey larger than itself.

这是一个很大的优势，因为鳗鱼吃的东西很大。

That's a big advantage, because of the eel eats something big.

所以鳗鱼可以在它还没找到食物之前就走一段时间。

So the eel can go for quite a while before it has to find food again.

在一些深海生物中，另一种有益的适应是产生光的能力，

Another helpful adaptation in some deep-sea organisms is the ability to generate light,

一些生物利用这种光来帮助他们捕捉食物。

and some organisms use that light to help them capture food.

例如，有一种叫做琵琶鱼的鱼，

For example, there's a kind of fish called the angler fish,

在它的头部，这条鱼有一个小的结构，可以产生在黑暗中发光的光。

and on its head, this fish has a little structure that produces light that glows in the dark.

这个小小的结构，这个小小的光，被放置在靠近鱼嘴的地方。

This little structure, this little light, is positioned close to the fish's mouth.

它们认为这是他们可以吃的东西，

they think it's something small they can eat,

这使它们足够接近琵琶鱼捕捉它们并吃掉它们。

and that brings them close enough for the angler fish to capture them and eat them.

 Using the examples of the eel and the anglerfish, explain the two types of adaptations that help animals survive in the deepest part of the ocean.
