Passage One
短文一
Do you know that bees can dance?
你知道蜜蜂可以跳舞吗？
Well, neither did scientists, until the 1960s.
就连科学家也是在20世纪60年代才发现的。
That's when a German scientist, named Karl von Frisch, noticed something truly remarkable.
德国科学家 Karl von Frisch注意到了这一重大发现。
As he was observing honeybees, he noticed that some of the bees, which he called scout bees, flew out of the hive to look for food.
对蜜蜂进行观察时，他发现有些侦察蜂离开蜂巢外出觅食。
When a scout found a site where there was food, it flew back to the beehive and started dancing.
一旦发现食物源，侦察蜂会立即飞回蜂巢并且开始跳舞。
This dance somehow told the other honeybees where the food was,
这支舞蹈意在告诉其他蜜蜂食物的来源，
because after the dance, some of the bees flew from the hive straight to the site of the food.
因为舞蹈结束后，有的蜜蜂会径直飞向食物所在之处。
Karl called the bees that collect the food forager bees.
Karl将这种蜜蜂成为觅食蜂。
He thought the scout bee's dance told the forager bees three things:
Karl认为侦察蜂通过舞蹈传递给觅食蜂三个信息，
first, the smell of the food it had found;
其一是食物的味道，
second, which direction to fly to reach the food;
其二是食物的大致方向，
and third, the distance of the food site from the beehive.
其三食物离蜂巢的距离。
Karl won the 1973 Nobel Prize for this discovery, but many scientists were skeptical of his theory.
凭借这一发现，Karl获得1973年的诺贝尔奖，但仍然有许多科学家质疑他的理论。
They didn't believe it was the dance that led the forager bees to food.
他们不相信觅食蜂是通过舞蹈发现食物的。
Instead, they thought it might be, oh, the smell of the food on the dancing bee,
相反，他们认为觅食蜂可能闻到了侦察蜂身上的食物气味，
or maybe that they just followed the scout back to the food site.
或者只是跟着侦察蜂发现食物的。
Well, very recently, some British scientists used a new type of radar to prove that Karl's theory was indeed correct.
然而，近日英国科学家使用新型雷达进行研究，证实了 Karl 理论的正确性。
It is the dance that communicates this information to other bees.
侦察蜂的确是通过舞蹈将信息传达给其他蜜蜂的。
