The meaning of the word “volunteer ” may be a little different in different countries, but it usually means “one who offers his or her services(服务).” there are many different ways in which people can volunteer, such as taking care of sick people, working in homes for homeless children, and picking up garbage(垃圾) from beaches and parks. Volunteers may work within their own countries or in other countries. They are often people with a strong wish to help those who are less fortunate than themselves. Volunteers don’t expect any kind of pay.

Tracy, a good friend of mine, recently came back from India with a new idea of what being a volunteer means. She worked for two and a half weeks in one of mother Teresa’s homes in Calcutta. The following is her story.

“I worked for sick people. I helped wash clothes and sheets, and pass out lunch. To be honest, I don’t think I was helping very much. It was then that I realized that I had not really come to help, but to learn about and experience another culture(文化) that helped improve my own understanding of life and the world.”
