There was a wonderful old man who loved everything. One day while walking through the woods, the old man f 86 a cocoon (茧). He took the cocoon home and placed it on his kitchen table and watched over it for days. Some days l 87 , the cocoon started to move. It moved frantically (疯狂地). The old man felt sorry for the little butterfly (蝴蝶) i 88 and gently cut the cocoon with a knife so the butterfly could c 89 out. The butterfly broke free from its cocoon, but c 90 move at all. The old man was in a puzzle (困惑) and placed the butterfly 91 into its cocoon. He thought it was the best thing he could do. He did 92 , and placed a drop of honey on it to seal (封上) the cocoon. The next day he noticed that the cocoon was moving a 93 . It tried and tried. Finally the butterfly broke free from its cocoon himself and stretched (伸展) its wings out. It took off! It was f 94 ! And that wonderful butterfly flew and flew till it was almost out of the old man’s sight. What a joy! He shouted. But then he started to think. What did he do wrong at f 95 ?
