When my son, Justin, was four, he found a caterpillar（毛毛虫）and put it in a box. Each day he          it fresh grass and leaves . In a few weeks, the caterpillar became fat and was ready to sleep. One morning we found         had become a cocoon(茧).
Justin was        . He knew a moth（飞蛾）or butterfly was going to be        .
“Dad !       is happening. Come and look!” He shouted happily. We could clearly see the wings        . A few days later, a beautiful black moth broke free from its cocoon.
The next day, Justin took the         outside and opened it, and the little moth flew out. It flew around the yard twice,        , and landed on Justin’s arm. He picked it up and threw it in the air,         the moth came back again. He tried over and over to set it free, but each time it would return to his arm.
I believe the moth, just like a person, was afraid to         comfortable places and situations. It wanted to stay with something         and was afraid to move on and experience new things.
I was once that little moth. My cocoon was my mother’s love which made me comfortable.        the moth, I didn’t want to fly too far from it. When my first job required me to move to a new city, I was         but later I chose to move there. And finally, I found I was happy about my          .
Humans are animals of habit. We         change. However, if we hadn’t moved, we would not have experienced many new things. So spread your wings and fly.
