In the African country of Tanzania, a company from Belgium called APOPO trains African giant pouched rats(非洲巨袋鼠) to find dangerous land mines(地雷)left over from wars. The rats are trained to smell out some of the chemicals in the mines. After 8-12 months of training, the rat can find mines so they can be safely destroyed.

       Trained dogs often perform this important work, but APOPO director Bart Weetjens recently discovered that the African giant pouched rat costs far less money to train and care for. These rats may seem huge. Their bodies are 12 to16 inches long, not including their tails. But their size suits the job: At one and a half to 3 pounds, they are too light to set off the land mines.

       Rats and trainers search one small area at a time. When a rat smells mines, it lets the trainers know by pawing(用爪子抓)at the dirt in that spot. The trainers mark each spot on a map. Later, technicians explode the mines safely. In the African country of Mozambique, nearly half the population is younger than 15 years old. A lot of kids are in danger as they play or work.

       “In the town of Vilanculos, children had been playing on the football field, until there was an accident,” Bart Weetjens said. APOPO rats and trainers helped other organizations make the area safe. “The football field has been opened again, and there is no danger any more,” Weetjens said.

       About 80 million land mines are buried out of sight in more than 60 countries around the world. As APOPO’s program grows, the rat heroes might travel the globe!

Insistence or Giving up
There is a battle in our daily life. Two forces are fighting with each other again and again. They never stop until you are buried in the earth. We called them insistence and giving up. They are like twins. One is angle, and the other is a demon..
As we all know, we want to pass the CET-4. So we get our own strategy. First of all, I am bound to master five thousand vocabularies. Second, I will write an article every week which is at least two hundred words. Then I will read at least two English articles, make more friends with foreigners for learning native English, and listening to some English news broadcast every day.
Nevertheless, according to my strategy, the first day, I should wake up at 6 a.m. to memorize at least twenty words. The alarm clock rings for me; I should get rid of my bed in order to study. Suddenly, “Giving up” came and whispered to me. “What about a five-minute prolong sleeping? How soft, comfortable this bed is! But Ms Insistence urged me, “Don’t listen to him; Come on, let’s carry out our plan.” Her voice is sweet, but not what I need.
Time flies! If we can’t seize every opportunity to appreciate time, Mr. Giving up will win all the time. Insistence of your plan, your dream may not be accomplished successfully, but giving up, you are sure to fail in life. (237w)
