A thirsty crow(乌鸦) comes across(偶然遇到) a bottle of water, but the water level is out of its reach. The bird then drops some stones into it and gets the water.

“It's just a story, ” you may think. But new research has found that crows' brains may sometimes be better than those of 6?year?old children.

In a recent experiment, American scientist Corina Logan and her team caught six crows to test them. The crows and children had to choose between two sets of tubes(试管). They had to drop stones in and get water.

With the red set, when they dropped a stone into a wide tube, the water level raised in a connected narrow tube. The blue set of tubes, however, had no connection between them.

Children aged 7 to 10 were able to learn the rule. Children aged 4 to 6, however, failed. Five of the six crows failed the test. But Kitty, a 6?month?old crow, passed it. She put most of the stones into the red tubes.

So, could a bird be more clever than a kindergartner? Don't be too quick to say no.

A little stream(小溪) ran down from a high mountain through many villages and forests. Then it reached a desert, “I went through so many difficulties. I should have no problem crossing the desert, ”she thought. As she started, she found herself slowly disappearing into the sand. After many tries, she still failed.

At this time, a deep voice said, “If a breeze(微风) can cross the desert, so can a river.” It was the voice of the desert. But the little stream answered, “That's because a breeze can fly, but I can't.”

“That's because you can't give up what you are. Let yourself evaporate(蒸发) into the breeze, and it can take you across,” said the desert.

“Give up what I am now? No! No!” The little stream could not accept this idea.

“The breeze can carry the vapor(蒸气) across the desert and let it leave as rain. The rain will form a river again,” said the desert.“And whether you're a river or vapor, your nature(本性) never changes.”

Hearing this, the little stream went into the open arms of the breeze. It carried her to the next stage(阶段) of her life.
