Unexpectedly，the first lesson I taught turned out（打扫，生产，关掉）a lesson for me. The moment I stepped into the shabby（破旧卑鄙）classroom. I was touched by the loud, respectful voices in unison（一致，和谐）. 'Good morning teacher !' Instead of fooling around, the children were thirsty for knowledge and efficient in absorbing（吸引人的有趣的） everything I was able to give them. This made me despise(轻视) myself for I hadn't even prepared for the class. During the break. I leaned over（弯下身子）the squeaky（支支作响） desk, chatting with a sweaty（出汗吃力的） boy in the front row. "Without air-conditioning, It's really hot here. Are you tired?" Not at all. said he. shaking his head. it's fine here. My Dad builds asphalt（沥青）roads. That is really tiring and hot.

As summer advanced. my enthusiasm as a teacher grew. I prepared my lesson carefully and even used some methods my teachers used. I organized many group activities to give the kids fun. Strangely enough the heat was also becoming less and less unbearable. Soon, my one-month volunnteer came to an end. When I was leaving my last class, I turned back and saw smiling faces and waving hands. Never before had I ever had such a feeling of sadness. which was, nevertheless, mixed with a sense of enrichment, fulfillment and happiness. I was paid for my work, amply（充足详细的） paid, not in terms of money, but something more valuable.

My English was improved, I was able to teach it, although not very professional. I learned about the grassroots-level society. Inside myself a heart is growing. a heart that not only beats for myself. but cares for others as well. The volunteer work gave me a precious(宝贵) little chance of saying thanks. to people like the little boy's father who construct highways and undergrounds, build up(树立, 增进) modern skyscrapers(摩天大楼), and make our cities more and more beautiful. To help the children with their English was all I could do at present to show my gratitude（感谢得心情） to these unsung（未赞颂）heroes. The world may not have been fair to them. so privileged（特别恩典的） and blessed people like me make their life better. Whatever I do for them, however, I know it can't be compared with what they have done to improve the quality of life in our cities. Ladies and gentlemen. Now I realize that voluntary（自愿的） shouldn't be just a one-time personal experience. It should be a lifetime activity of everybody. Many of us are now offering assistance（协助补助）to the needy（贫困的）and to each other and our efforts have indeed made a difference schooling,----------- or caring for the elderly in nursing（看护养育） homes, and helping out（帮助，解决困难）in 2008 Beijing Olympics, will not only contribute to the harmony of the world but elevate（举起，振奋，提拔）ourselves as well. Emerson once said, "It's one of the most beautiful compensations补偿 of this life no man can sincerely（真诚的) try to help another without helping himself" He was right. I hear that my university is going to organize another voluntary teaching program this summer. This time I won't be dragged in. I will volunteer. Thank you !
