   One day a small opening appeared on a cocoon(茧), a man sat and watched for the butterfly for several hours as it was struggling to  1  its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten  2  it could and it could go no further. So the man decided to  3  the butterfly: he took a pair of scissors and  4  the remaining part of the cocoon. The butterfly then  5  easily.

   But it has a swollen(肿胀的) body and  6  wings. The man continued to  7  the butterfly because he expected that, at any moment, the  8  would enlarge and expand to be able to support the body, which would  9 in time. Neither happened!  10,  the butterfly spent the rest of its life  11 around with a swollen body and small, shriveled(褶皱的) wings. It  12  was able to fly. What the man did in his  13 and haste(匆忙)did no good to the butterfly. He didn’t know the  14  cocoon and the struggle  15  for the butterfly to get through the tiny  16 were the natural way of forcing fluid from the body of the butterfly into its wings  17  it would be ready for flight once it achieved its  18  from the cocoon.
