In every country, there are thousands of people who want to help out. Many join organizations run   by their governments, for example, the Peace Corps in the United States and Voluntary Service Overseas in Britain. Since the powerful   earthquake took place in Sichuan, more than 200 thousand volunteers across China have been helping there! They do all kinds of work or come up with ways to help improve life. Some offer their professional skills for free. Others have no qualifications  , but they love to work hard to help. One of the most famous volunteers in the world was Mother Teresa. She could be the best volunteer because she gave her life to helping the poorest people of Calcutta. She helped the homeless, cared for the sick, gave out food, and became the mother of those without families. Now more and more teenagers actively look for volunteering opportunities, too. They volunteer because they think it will be fun or they will learn something. They also like the idea of being helpful to others, even if it is just handing out books for the teacher. As they get older, these reasons are still the same, but there are other important reasons for volunteering such as learning on-the-job, getting work experience, and improving their social life. All volunteers bring joy to the people they help in so many ways. They might read books to the blind, fix up broken homes, find ways to get water for villages. Could you be a volunteer?
