One possible version

     In the picture there is an old man sitting alone on the bench in a park. He is looking at a young mother

holding the bike for her little daughter while she is riding it. By the side of the old man lies a sleeping little

pet dog.

     This is a plcture of great contrast. By the look on the man's face, we can tell the old man feels a bit

lonely. However, the little girl, enjoying her mother's company, is playing happily. Nowadays, all families

have only one child. So parents do whatever they can to take good care of their children. There's nothing

wrong with that. But meanwhile, as far as I'm concerned, not only the young but also the old in our society

deserve good care and enough attention. The needs of the old shouldn't be ignored.

     In conclusion, we shouldn't lose the good tradition of caring for the old.
