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(剪刀) 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___ as 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!

One night, I wondered what it would be like if I only asked questions. I decided that no matter what anyone said to me the next day, I would reply only with   36 .
I loved to read about scientists and their discoveries, and I knew that scientists always started their research with a question. I hoped that I could become a scientist. Maybe by asking questions, I could train my mind to be   37 .
I survived the morning easily. “Is there any egg?” I answered when my mother asked what I wanted for breakfast. “Is this seat taken?” I asked when my friend Mike asked where he was going to   38  on the bus.
In the classroom, Mr. Black spoke slowly and clearly while I listened carefully. The problem had been part of my homework the night before. I wrote the answer on the board, “Could the answer be 361?”
Mr. Black smiled and nodded. I thought,“How did I   39  to get through that?” I almost laughed because asking questions really was starting to become a   40 .
I thought I had made it safely through the whole day,   41  what I had come to consider my experiment blew up at the dinner table when my dad asked me about my day. “What do I always do?” I replied.
My parents looked at each other. My father   42  again. “Well, I hope you went to school,” he said.
“Uhhh … why would you think otherwise?” I asked. My parents exchanged another   43   
and were becoming annoyed.
“Do you think questions are a good way to train your mind to be active?” I asked.
“It   44  the question,” said my father. “Some questions are asked for   45  information. Those are good mind-training questions. Sometimes, people use questions to get the other person to say something. Sometimes people ask questions to get someone to agree with them. Those questions don’t really achieve anything.”
“I guess my experiment didn’t work,” I said, and I told my father about my   46 .
“I think it worked   47 !” my father said. “You made a discovery, didn’t you? What matters is that you have put your idea into practice.”
