The poor are very wonderful people. One evening my sisters and I went out and picked up four people from the street. One of them 31 a most terrible condition. I told my sisters, "You 32 the other three. I take care of this one who looks 33 .”So I did for her all that my love can do.I 34 her in bed, and there was such a beautiful smile on her face. She took hold of my hand as she 35 ‘'Thank you" and then she died. I could not help but examined my heart before her. I asked myself 36 I would say if I was in her place. My answer was very simple.1 would say I was hungry, cold, homeless, and I was dying, or something else, but she gave me her 37 love. Then she died with a smile on her face.

So let us always meet 39 with a smile, for the smile is the 40 of love, and once we begin to love each other naturally, we will do something for others.

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 minefiel山 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 ~he 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.
