Question

【题目】Scientists have always believed that snails are not able to find their way home. But Briton Ruth Brooks, a retired teacher, has found that it is not true.

Brooks started working on snails after she got angry with the snails in her garden. The snails ate her vegetables. She didn't want to kill them, so she took them to another place. But she found they always seemed to come back. Brooks tried to mark the snails in her garden with nail polish (指甲油). She placed the snails in the place around her home and made notes of their movements. She found that snails have a strong homing instinct (本能); the longest returning snail traveled back 90 meters.

People started to call Brooks Britain's best amateur (业余的) scientist after her work won the BBC's prize “To Be A Scientist”. She said, “I've always wanted to know whether the snails that eat my plants just come back when I move them, and if they do, how far is it from their home?” "I would say on the evidence (证据) that it would be safe to take your snails away 100 meters or even farther. If you put them somewhere nice with some food, you can be almost sure that they won't come back."
