Have you ever been ill? When you are ill,you must be unhappy because your body becomes hot,and there are pains all over your body. You don't want to work,you stay in bed,feeling very sad.

What makes us ill? It is germs(细菌). Germs are everywhere. They are very small and you can't find them with your eyes,but you can see them with a microscope. They are very small and there could be hundreds of them on a very small thing.

Germs are always found in dirty water. When we look at dirty water under the microscope,we shall see them in it. So your father and mother will not let you drink dirty water.

Germs aren't found only in water. They are found in air and dust. If you cut your finger,if some of the dust from the floor goes into the cut(割开处),some of the germs would go into your finger. Your finger would become big and red,and you will have much pain in it. Sometimes the germs would go into all of your body,and you would have pain everywhere.

One day, a boy found the cocoon(茧) of a butterfly and brought it home. A few days later, the boy saw a small in the cocoon. He sat and watched for several hours as a butterfly tried to make body through that little hole. Suddenly it stopped.

The boy decided to the butterfly, thinking the butterfly might be thankful. He took out a knife and cut the hole to make it .The butterfly came out of the cocoon but it looked a little different. It had a weak body and small, thin . The butterfly didn’t start to fly. In fact, the butterfly spent the rest of its life crawling(爬行) around with a weak body and thin wings. It was able to fly.

The boy acted with kindness, he didn’t understand why it could be like this. When a butterfly crawls out of the cocoon, it must try very hard. The hard work of getting out of the cocoon makes its wings strong. It helps the butterfly be to fly. If the butterfly doesn’t have to try hard to get out of the cocoon, its wings won’t get strong enough for it to fly.

In our lives, pain is the key all windows. Without it, there’s no way of life. We can’t difficulties or problems. So, next time you have a problem or difficulty, remember the butterfly. Try hard—then fly!
