Passage 1 比利时一家非政府组织训练小老鼠帮助清除邻国莫桑比克的地雷
(河南省信阳市淮滨县2022-2023学年高二上学期11月期中英语试题)
A baby rat is being trained by APOPO, a pioneering Belgian non-governmental organization (NGO). Other rats trained under the same project have already helped clear large areas of land in neighboring Mozambique, a country littered with mines (地雷).
Training begins at four weeks old when the baby rats are exposed to humans and new surroundings, after which they are taught to associate a click sound with food. Once that is achieved, they are then trained to tell TNT scent from other smells. When they successfully tell it, the click is sounded and they are given a bit of banana, thus strengthening the link between TNT and food. In all, it takes nine months of on-and off-field training for a rat to be ready for mine detection (侦察).
“This work is not easy,” said trainer Abdullah Mchomvu. “You have to be patient. Sometimes I get angry, but then again I tell myself these are animals.” But “this work saves lives”, he added.
“Detection is the most difficult, dangerous and expensive part of mine clearing. Since rats are much easier to train than dogs, rats in this environment are much better,” said Bart Weetjens, the founder of APOPO.
“They are very effective. So far they have helped re-open almost two million square metres of land” in Mozambique. Despite their contribution, rats are more often seen as vermin (害虫) that spread disease and destroy harvests.
“People don’t like rats and that is one of our biggest struggles,” said Weetjens. “We are trying to change that belief. Rats are very sociable, very intelligent, highly likeable creatures.”
APOPO calls them “hero rats” in recognition of the work they perform. Weetjens said the next step would be to use the “hero rats” to search for survivors of disasters such as earthquakes.
