When I was seven years old, my family made me an ant farm(蚂蚁窝). 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 something terrible happened. I put my face so close to the glass farm that I knocked it over. All the tunnels fell down. Although(虽然) the ants kept alive after their earthquake, one by one they began to die. I was frightened as I watched them give up building their tunnels to carry the bodies to a corner (角落)of the farm.

My mother said that the ants were dying of sadness. They simply could not stand(忍受) 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.
