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 began to die. I was scared as I watched them give up building their tunnels to carry the bodies to a corner 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 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.
