One day, a boy found the cocoon(茧) of a butterfly and brought it home. A few days later, the boy saw a small   31  in the cocoon. He sat and watched for several hours as a butterfly struggled to make   32   body through that little hole. Suddenly it stopped.
So the boy   33   to help the butterfly, thinking the butterfly might be   34  .He took a pair of scissors and cut the hole   35  .The butterfly came out of the cocoon but it   36 a little different. It had a weak body and small, thin   37  .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 never able to fly.
The boy acted with   38   but he didn’t understand why it could be like this. When a butterfly crawls out of the cocoon, it must struggle. The hard work of   39   out of the cocoon makes the fluid(液体) from the butterfly’s body into its wings. It helps the butterfly be   40   to fly. If the butterfly never has to squeeze(挤压) itself out of the cocoon, its wings will never get the fluid and it can never fly.
  41   struggles are what we need in our lives. If we lived our lives without any problems, we would never learn or grow. We would not be __42__ we could have been and we would never fly.
In our lives, pain and suffering is the key to all windows, and sometimes even   43   growth, without it , there’s no way of life. We can’t avoid   44   or problems. So, next time you are   45 a problem or difficulty, remember the butterfly. Struggle a little—then fly!
