旁白：现在来听生物讲座上的一部分内容。

Narrator: Now listen to part of a lecture in the Biology class.

教授：我们有一个很好的例子，臭鼬。

Professor: We have a good example of this with the skunk.

臭鼬是一种毛茸茸的小哺乳动物，在北美随处可见。

the skunk is a furry little mammal that can be found throughout North America.

它们有一条白色的条纹，从头顶，

and they have a big white stripe that runs from the top of their head,

一直沿着他们的后背，延伸到它们那又大又浓密的尾巴上。

all the way down their back and along their big, bushy tail.

所以它们很容易被看到，甚至从远处也很容易辨认。

So they are very easy to see and very easy to recognize even from a distance.

臭鼬的尾巴下也有特殊的腺体，产生一种有难闻的气味的液体。

Skunks also have special glands under their tail that produce a terrible smelling liquid.

And when skunks are approached by a predator,

它们抬起尾巴，用这种液体喷向捕食者。

they lift their tail and spray the predator with this liquid.

假设一只狼正准备攻击一只臭鼬。

let's say a wolf is preparing to attack a skunk.

臭鼬抬起它的尾巴，向狼喷射。

the skunk lifts its tail and sprays the wolf.

这对狼来说是非常非常不愉快的，

That's very, very unpleasant for the wolf,

因为它现在被这种令人厌恶的恶臭液体所覆盖。

because it's now covered with this repulsive foul smelling liquid.

The wolf doesn't want to be sprayed again,

so it backs off and leaves the skunk alone.

每当那只狼看到一个毛茸茸的小黑身体，一条白色的条纹从头延伸至尾巴，

whenever that wolf sees a furry little black body with a big white stripe running from its head to its tail,

Warning Coloration &nbsp;
Many animals have defense mechanisms that help protect them from predators. In some cases, these animals have distinct coloring that signals predators of the presence of such defenses. This type of coloring is called warning coloration. If a predator does not recognize the meaning of this coloration and attacks, it may suffer significant discomfort or injury when its would-be prey employs its defense mechanism. As a result, the predator learns to associate the warning coloration with negative consequences, and will from that point forward avoid attacking animals that have that coloration.&nbsp;
