There are about 80,000,000 mines (地雷) under the ground in more than 60 countries. It is difficult and dangerous to clear these mines. About 50 people including many children were killed or hurt each day. In 2003, APOPO, a Dutch research company that trains the animals, came up with the idea of using 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 1.35kg, 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 not afraid of people and the things around them anymore. Then they were trained to connect a click sound with food. After the rats had learned 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 searched the ground to tell the domineers (排雷员) that they smelt out a mine. Then the mine was cleared. It had taken two domineers 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 domineers 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 Weetjens, the head of the APOPO.

When I was seven years old, my mom was diagnosed（诊断）with cancer. The doctors told us my mom might be saved with operation. But it could also kill her. She chose to have it.
The day before the operation I was off school, and my mom planned the best day of my life, everything I loved at seven and everything that would put a smile on my face. The day began with her waking me up saying, “Kate, I have a surprise for you. Come and see.” The surprise was a doll I had wanted for the longest time. Throughout the day, she told me everything that she thought I would need to know to grow up and be a good person; she told me to be the best I could be and that I would always make her proud. We had a picnic in the park, and it was so cold that we moved to the car. The day was filled with laughter. For the first time in a long time I could see she was really happy. I would never forget her smile, or the way her eyes shone as if we were the same age. It was the best day of my life, and I will never forget the conversations we shared.
My mother managed to live through the operation. Now when I look back, I realize that the best day of my life could be her last and this could be the last day I would remember with her, the last one we shared. I also understand how unselfish a mother is.
