托福TPO/Official 43 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：来听生物课上讲座的一部分。

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

教授：好的，我们一直在讨论大多数动物在需要食物时所做的事情，

Professor: Okay, so we've been talking about what most animals do when they need food,

但是有些动物在需要食物的时候会做一些完全不同的事情。

But some animals do something entirely different when they need food.

有些动物实际上花了大量的时间来照顾自己的食物来源。

some animals actually spend a great deal of time taking care of their own food source.

它们培养食物，就像人类的农民一样，

They cultivate it, sort of the way human farmers would,

食物会一直生长直到它准备好让动物使用。

so it will keep growing until it's ready for them to use.

让我们从培育植物的动物开始。

Let's start with an animal that cultivates plants.

它被称为“雀鲷”，喜欢吃一种特殊的海藻。

it's called a damselfish that likes to eat a special kind of seaweed.

So wherever a patch of the seaweed grows,

通常会有雀鲷在上面和周围游动。

there will usually be damselfish swimming above and around it.

现在这鱼在那里为了保护藻类不受其他植物的侵害，

Now the fish are there to provide protection from other plants,

这样藻类就能生长并在雀鲷鱼吃掉它们后再次生长。

so the seaweed can grow and then regrow as the damselfish eat it.

如果其他植物开始生长在海藻旁边挡住阳光，

if other plants start growing over the seaweed blocking sunlight,

雀鲷咬掉那些这些植物长得太高的部分。

the damselfish remove those plants by biting off the parts that are getting too tall.

因此，通过保护海藻免受其他植物的破坏，

So by protecting the seaweed from being overrun and damaged by other plants,

雀鲷总是有现成的食物可以食用。

the damselfish always have a supply of food ready to use.

它们把其他动物作为食物的来源悉心照顾。

they take care of other animals as a source of food.

有一些种类的黑蚂蚁会照顾一种叫做蚜虫的微小昆虫。

there are some species of black ants that care for tiny insects called aphids.

这些蚜虫会产生一种蚂蚁喜欢吃的甜味液体，

These aphids produce a sweet liquid that the ants like to eat,

因此，蚂蚁保护蚜虫不被其他动物吃掉，并帮助蚜虫进食。

so ants guard the aphids from being eaten by other animals and help feed the aphids.

事实上，有时蚂蚁甚至会把蚜虫的卵带回自己的巢里，

In fact, sometimes the ants even carry aphid eggs back to their own nests,

然后蚜虫会长大并产生蚂蚁所吃的甜味液体，

Then the aphids grow and produce a sweet liquid that the ants eat,

蚂蚁利用蚜虫作为一种可靠的食物来源。

so the ants make use of the aphids as a reliable source of food.
