     Last summer I went through a training program and became a literacy volunteer (扫盲志愿者). The

training I received, though excellent, did not tell me how it was to work with a real student, however.

When I began to discover what other people's lives were like because they could not read, I realized the

true importance of reading.

     My first student Marie was a 44-year-old single mother of three. In the first lesson, I found out she

walked two miles to the nearest supermarket twice a week because she didn't know which bus to take.

When I told her I would get her a bus schedule. She told me it would not help because she could not read

it. She said she also had difficulty once she got to the supermarket, because she couldn't always remember what she needed. Since she did not know words, she could not write out a shopping list. Also, she could

only recognize items by sight, so if the product had a different label, she would not recognize it as the

product she wanted.

      As we worked together, learning how to read built Marie's self-confidence, which encouraged her to

continue in her studies. She began to make rapid progress and was even able to take the bus to the

supermarket. After this successful trip, she reported how self-confident she felt. At the end of the program, she began helping her youngest son, Tony, a shy first grader, with his reading. She sat with him before he

went to sleep and together they would read bedtime stories. When his eyes became wide with excitement as she read, pride was written all over her face, and she began to see how her own hard work in learning

to read paid off. As she described this experience, I was proud of myself as well. I found that helping

Marie to build her self-confidence was more rewarding than anything I had ever done before.

     As a literacy volunteer, I learned a great deal about teaching and helping others. In fact, I may have

learned more from the experience than Marie did.
