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!
