小学生10分钟应用题系列答案There are about 80,000,000 mines* under the ground in more . than 60 countries. It is difficult and dangerous to clear these rnines, About 50 people including many children were’ killed ‘or htirt each iay. In 2003, APOPO, a Dutch research com pan y that uains the an imals, came up with the-idea of s\ng rats to search for the mines.
The animal trainers ‘found that a kind of rats from Africa were clever and had.a sharp* sense of smell. The rats were about 75 cm long and.weighed about l.35 kg, light enough to run across a minefield without setting off the mines.
In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed that, the trainers then taught them to tell the difference between the smell of mines and other smells. When the rats could do it, the click was sounded and they were given a bit of banana. The method was called clicker training. “The training isn’t easy, said trainer Abdullah Mchomvu. “You have to be patient. Sometimes I get angry, but then again, I tell myself these are animals.”
After nine months’training, the rats were taken to a minefield. They’ran across the minefield, stopped, sat and scratched the ground to tell the deminers* that they smelt out’a mine. Then the mine was cleared. It had taken two ‘deminers a day to clear a 200㎡ . minefield, but with the help of two rats ‘they could finish it in two hours.
The rats and the deminers saved thousands of lives, “The rats did this job much better than we expected. So far they have helped to make almost 2,000,000㎡ of land safe. They are heroes,” said Bart Weeqens, the head of the APOPO.

New York is one of the last large American cities to have some of its policemen on horseback. The New York police have 170 horses working in certain parts of the city. The horses are expensive to feed, but it is even more expensive to look after them. Because the horses must walk on the streets, they need special horseshoes. In fact , they need more than 8,000 of them each year. Every police horse in New York gets new shoes every month. Keeping these shoes in good repair is the job of six blacksmiths. There are only about thirty-five of these blacksmiths in the whole United States.
The cost of shoing a horse is between twenty dollars and thirty-five dollars, and it takes a good blacksmith two or three hours to do the job.
A blacksmith’s job is not an easy one. He must be able to shape a shoe from a piece of metal and then fit it to the horse’s foot. The blacksmith must bend over all the time when he is fitting the shoe and must hold the weight of the horse’s leg while he works. Clearly, a blacksmith must be very storng. But even more important, he must be able to deal with horses---for before the blacksmith can begin his work, he has to get the horse to lift its leg.
One of the blacksmiths in New York is James Corbin. He came to the country from Ireland in 1948. He not only makes horseshoes for the police but also works for a group of horse owners near the city. Corbin became interested in blacksmithing because his father did it, and,as the puts it, “It’s a good way to make a living.”
