On the first day of school our teacher let us know someone. Looking out, we found an old woman appeared at the door. She said, "Hi, my name is Susan, I'm seventy years old." While we were  41  what made her take this challenge (挑戰(zhàn)) at her age, she said with a smile, "I/m here to meet a rich husband, get   42   , have two children and travel together. "Hearing this, all of us laughed. "In fact," she went on, " I always   43   of having a college education, and now I'm getting one!"

     After class we had chocolate and milk together. We became good   44  . 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   45   . When she was stepped up to the front, suddenly she found she took the wrong paper. She felt a little frustrated (沮喪的) and said, "I'm sorry. I'm so nervous that I can't get my ready talk back , so I have to tell you   46   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   47   , being happy and getting success is that we should laugh and find something   48   every day. I think there is a great   49   between growing old and growing up.

Growing older can't be avoided (避免的), growing up can be   50  , 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 wherever she went. In the end, the wonderful woman got a college degree.
