A man found a cocoon of a moth. He took it home so that he could 31 the moth come out of the cocoon. On that day a small 32 appeared, he sat and watched the moth for several hours as the moth struggled to 33 the body through that little hole. Soon it seemed to stop making any progress. It appeared as if it had 34 as far as it could and it could go no farther. It just seemed to be stuck. So the man, out of his kindness, decided to help the moth. He took a pair of scissors and cut off the 35 bit of the cocoon. The 36 then came out easily. But it had a swollen body and small, shriven（无用的） wings. The man continued to watch the moth because he expected that, at any moment, the wings would enlarge and 37 to be able to support the 38 , which would get smaller in time. Neither happened! In fact, the little moth spent the rest of its life 39 around with a small, swollen body and shriveled wings. It was 40 able to fly. What the man in his kindness 41 was that the small cocoon and the 42 of the moth to get through the 43 opening was a way to push fluid(液体) 44 the body of moth 45 its wings so that it would be ready to fly 46 it got out of the cocoon. Freedom and 47 would come only after the struggle. By taking the moth of a struggle away, he also took away the moth’s health. Sometimes struggles are exactly what we need in our life. If we were to 48 our lives without any difficulties, we would be disabled. We would not be as 49 as what we could have been.
