Literacy Volunteer 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 Jane 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 their labels. As a result, 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 Jane'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, too. I found that helping Jane 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 Jane did. I once could not read.()
