Yesterday, our teacher asked us when a man could be referred as an old man. David stood up and said people with wrinkles could be called old people, However, Mary didn’t      , for some people may gain wrinkles at an earlier age owing to their     work. Then Lily expressed her idea that those reaching their 60s or more could be called old people. This time, Emily expressed her      that some old people may still be energetic and trying to pursue their dreams, which makes them appear        . The class was over and we still didn’t reach any       , so the teacher asked us to think about it after class.

The     has reminded me of the saying of J. Barrymore that a man isn’t old as long as he is ___    something.

My grandma is such a woman who pursues her dream      when she’s 70 now. She has        her dream of being a painter since she was a little child. , because her family was poor, she had to   her dream and stepped into the to raise money so as to support her family. Though she has      abandoned her dream, she could hardly find any    to realize it because of the tough work.     , chance came when she retired from her work. She began taking her painting lessons       .she had all-white hair and lots of wrinkles. At first, I was     her idea of attending school at so old an age, but after seeing her paint happily and enjoyably, I     feeling it a good choice. She seems energetic and      fine.

So if we have our dreams and seek for them, we aren’t old. It’s when we don’t know what we want and let     be the center point of our lives that we can finally be regarded as the old.
