Directions: Put the following sentences in the proper order so that they make a complete paragraph. 1. One day while walking through the woods the nice old man found a cocoon of a butterfly. He took it home. 2. Once upon a time in a land far away, there was a wonderful old man who loved everything: animals, spiders, insects, etc. 3. A few days later, a small opening appeared; he sat and watched the butterfly for several hours as it struggled to force its body through that little hole. 4. Then the man decided to help the butterfly, so he took a pair of scissors and snipped off the remaining bit of the cocoon. The butterfly then emerged easily. 5. Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could and it could go no further. 6. But it never was able to fly. 请把你的排序方式写在空白处。数字之间用一个空格分开。
