People say bees can always find the way home. Wherever you put them, they can come back. John
Smith didn't believe this, so he did an experiment (实验).
He caught 20 bees under the eave (屋檐) of his house and put them in a bag. He asked his daughter to
wait there and see if the bees would come back. He marked (作标记) the bees and took them two
miles away. Then he opened the bag and let the bees out.
When he got home, his daughter ran to him and shouted, " Two bees have come back." Both John and
his daughter were very excited. He went to see them at once. Yes, two bees were there. They flew about
two miles in three quarters. And they came back with pollen (花粉) on their bodies. It was getting dark.
No more bees came back home. John became worried.
The next morning, he came to see the bees again. To his surprise, another fifteen bees came back with
pollen on their bodies. As a result, John believed that bees really have the ability of finding their way
home.
