I learned about life from an ant farm. When I was seven years old, my family created one. First, we put clean sand in a thin glass box and put the ants into it. Soon they got to work making tunnels. I was amazed that each one knew exactly what to do. With my mom’s help, I kept a record of what happened each day and named the ants.

One day when I had put my face close to the structure (building), accidentally I knocked it over, and all the tunnels fell in. Although the ants survived their earthquake, one by one they began to die. I was frightened as I watched them give up their tunnel-building to carry the bodies to a corner of the farm. My mother reported that the ants were dying of “frustration (挫折)”. They simply could not stand the reality that their tunnels had been destroyed.

Although much time has passed, I still think of that ant farm. Over the years, I came to realize the ants have the spirit of teamwork. Working together, they were able to create an amazing world for themselves. I also learned that they should be admired for their hard work. Day in and day out, each worked at their task. The ant farm showed that teamwork and perseverance (毅力) are indeed the keys to success. 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, humans cannot give up when they face disappointment.

So I try to live my life like those hardworking ants. But, unlike them, I try not to let frustration defeat (击败) me. I will have to keep building my tunnels.

If you want to watch and know something about birds, you must find a good place near the bird nest（巢）.

Birds sit on eggs and take care of their babies from April to June. Because the baby birds are too young to leave the nest, parents often go to look for food and come back in several minutes. So it is good to watch birds. When we watch birds, we’d better hide ourselves in a close place to the nest, and it’s better to use binoculars(双筒望远镜).

But how to make a bird nest? A good bird nest must be very fine, strong, thick and comfortable. If you want to make one, please follow these:

a) Each nest must have six boards（木板）. Don’t make the boards too slippery（滑）.

b) Dig a small hole in the front of the nest as a “door”. The “door” is big enough so birds can fly in or out easily.

c) Make sure the rainwater can’t go into the nest.

d) One piece of the board should be easy to open.
