录音开头讲到在非洲很多地方，大象的拜访使农民苦不堪言，农民不得已采取极端措施，而说话者提到“In this case, therefore, prevention is better than cure for both sides”，可见说话者认为保护农田和野生动物同等重要。【录音原文】　　Elephants, proverbially, are afraid of mice. Well, it’s a nice story, but don’t rely on it to frighten the beasts from your smallholding. Poachers aside, the most dangerous thing an elephant is likely to meet is a disgruntled farmer with a rifle. And farmers have good reason to be disgruntled. In many parts of Africa, farms are routinely trashed by visiting elephants. In this case, therefore, prevention is better than cure for both sides. And some recently published research may point the way, using tiny creatures that elephants really are afraid of: bees.　　Although elephants are thick-skinned, they have sensitive patches behind their ears, under their trunks and around their eyes. Sometimes, according to bee-keepers, an entire herd can be stampeded by a swarm of bees. Researchers from Wild Animal Protection Institutes based in Kenya have tested the idea that elephants’ visits to farms might be discouraged by strategically placed bee hives. It seems they are—and that the hives do not necessarily even have to be occupied.
