听力文摘：乖乖看这（在线收听）

Point at a ball and a dog will look at the ball, whereas a cat will probably look at your hand.

当人手指着球的时候，狗会看着球;而猫很可能看着手。

Dogs seem to have a readyunderstanding of how human beings direct attention bypointing, and can follow our gestures almost as if they thought the same way we do.

似乎，狗能读懂人的指示并执行指示。狗和人类的思维方式好像是一致的。

Of course, dogs probably aren't born knowing anything about people.

当然，狗不可能天生就知道人的想法，

We just carefully train them to look, fetch, and so on, right? Or do we?

都是受过精心的训练：看、拿…是不是？

A comparativepsychologist at the Max Plank Institute in Germany,named Michael Tomasello ran a series of tests on dogs,in which they had to find which sealed container had yummy dog food in it.

德国普朗克学院的比较心理学家迈克尔对狗进行了一系列测试。他要求狗找出藏有美味食物的密封容器。

The only hint they got was from a human being who looked at or pointed at the right container.

而唯一的提示是人的眼神或指示。

This wasn't hard for dogs at all.

这项测试对狗而言是小菜一碟。

But it was hard for wolves.

但是狼却做不到。

Wolves that have been raised by people should have had the samesuccess at finding the sealed container, but they didn't.

本以为一直受人抚养的狼也能准确找出，可是，狼却失败了。

Even chimpanzees, which are verysmart animals indeed, weren't as fast at finding the food as dogs.

甚至十分聪明的黑猩猩，也比不上狗的速度。

What does this mean?

为什么？

One interpretation is that dogs do, in fact, have a natural ability to understand forms of human communication.

一种解释是狗确实天生理解人沟通的方式。

Even nine-week old puppies found the food, suggesting the skill is there beforetraining.

甚至是9周大的小狗都能找到食物，说明这种能力并非后天受训。

Wolves don't have the skill, suggesting that it has developed in dogs since the time theybranched off from their evolutionary predecessors.

而狼却不具备这种能力，狗和狼虽有共同的祖先，但是由于进化而形成差异。

There is debate about this idea.

虽然这一观点备受争议，

But Tomasello thinks that in the past fifteen thousand years, as human beings and dogs have evolved together, the basis for fido's ability to understand what youmean may have become encoded in his genes.

但是迈克尔认为，早在15000年前，人和狗都在进化过程中，那时，狗已经具备能力读懂人的想法并代代相传。
