When people hear the word "rat" they may think of dirty animals that spread disease. You may also connect the word "rat" with bad expressions. Indeed, rats generally are not beloved animals either in life the English language. But the rat trainers at the nonprofit organization, APOPO, see the animals very (different). They consider the rats lifesavers. (base)in Tanzania, APOPO trains giant rats to find landmines(地雷). And the rats with their extraordinary sense of smell are very suitable the job. APOPO calls their animal team HeroRats.
Worldwide there are 110 million hidden explosives left over from war. These explosives are still "live," or able to explode. Such landmines kill or wound 5000 people year. Humans (use) metal-searching devices to do this work for years. But trained rats do it better and also cost less money. When the rats (work) in the field find a landmine, they scratch on the ground. That's how we know. We place a little marker there, and then we can safely remove those and get rid of (they).
The giant pouched rat is large compared to other (kind) of rats. However, they still do not weigh enough (cause) a landmine to explode. So these rats can really be heroes. They show every day that they are worthy of that name.
