On the first day of school our teacher let us know someone. Looking out, we found an old woman 16 at the door. She said, “Hi, my name is Susan, I’m seventy years old.” While we were  17 what made her take this challenge (挑战) at her age, she said with a smile, “I'm here to meet a rich husband, get  18 , have two children and travel together.” Hearing this, all of us laughed. “In fact,” she went on, “I always    19 of having a college education, and now I’m getting  20 !”
After class we had chocolate and milk together. We became good  21 . I often listened to this “time machine” as she shared her study with me.
At the end of the term we invited Susan to give us a  22 . When she was stepped up to the front, suddenly she found she took the wrong paper. She felt a little frustrated（沮丧的） and said, “I'm sorry. I’m so nervous that I can’t get my ready talk    23 , so I have to tell you  24 I know .”
In her speech she told us, “We don’t stop playing as we are old, we grow old because we stop playing. The secret of staying  25 , being happy and getting success is that we should laugh and find something  26 every day. I think there is a great  27 between growing old and growing up. I am seventy now. If I  28 in bed for one full year and never do anything. I’ll become seventy – one. Since anybody can grow older, my idea is to grow up by always finding the chance in change. Growing older can’t be avoided(避免的), growing up can be  29 . It’s never too late to be all you can be possible.”
During the four years’ study, it was so easy for Susan to make friends  30 she went. In the end, the wonderful woman got a college degree.

The story is _________ and all of us are _______ in it.
