There are about 80.000.000 mines 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 Duch 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 weighted about 1.35 kg.light enough to run across a minefield without setting off the mines.
In January 2004,the  APOPO startec this preject.First ,the trainers let the 4-week-old baby rats get familier with humans. A few weeks later,the rats were no longer afraid of people and the things around them.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 different 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 bananas.The method was called clicker training.“The training isn’t easy.”said the trainer Adulish Mebomvu.“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 4 minefield. They ran across the minefield ,stopped, sat and searched 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 m2 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 helpde to make almost 2.000.000 m2 of land safe.They are heroes.”said Bart Woetjcds.the head of the APOPO.

    When I was seven years old, my family made me an ant farm. First, we put clean sand in a thin glass box. Then we waited for the ants to arrive.
After the ants were in the glass farm, they started to make tunnels(地道). I was amazed that each one knew exactly what to do. Each had its own job.
On the fifth day a tragedy(悲剧)happened. I put my face so close to the glass farm that I knocked it over. All the tunnels fell down. Although the ants remained alive after their earthquake, one by one they began to die. I was scared as I watched them give up building their tunnels to carry the bodies to a corner of the farm.
My mother said that the ants were dying of sadness. They simply could not stand that their tunnels were gone.
Although much time has passed, I still think of that ant farm. Mom had hoped it would teach me about the natural world, but it taught me much more.
Over the years, I came to realize the importance of teamwork. Working together, the ants were able to make an amazing world for themselves. I also learned that they should be admired(钦佩)for their hard work.
But there was an even larger lesson that I did not realize until recently: Adversity(逆境)is a natural part of life, and must be accepted. Unlike the ants, we cannot give up when we are sad. We have to realize that if a tunnel is gone, we must build another.
Giving up, I say, is not a good choice.

Dear editor( 编辑),       

Can't your newspaper do something about the custom (习惯) of hitchhiking?

A short time ago, on a car travel I counted at least 50 people standing beside the road, asking for rides. Many of them were young women.

Don't they understand how dangerous it is to get into the car driven by a stranger? How much do they know about the driver? Is he a good driver or not? They know nothing!

Many of these young hitchhikers may come from good families. Don't their parents teach them anything about the world? I always taught my children not to talk to strangers. I never let them take rides from people they didn't know.

Isn't there enough crime (犯罪) today without asking for trouble by hitchhiking? On the other hand, hitchhiking may bring some traffic trouble. Don't you think what I said is true?
