     Mother Teresa, whose name was Agnes Gonxha Bojaxhiu, was born on August 26th, 1910 in Skopje, Macedonia. She always wrote her birthday as 27th of August because it was the day of her baptism

(洗礼), which was always more important to her than her birthday. For her work with the poor around the world, she received the 1979 Nobel Peace Prize.

     In 1928, she accepted a religious order and took the name Teresa. The order immediately sent her to

India. A few years later, she began teaching in Calcutta. In 1948 the Catholic (天主教的) Church agreed her request and let her enter the convent (女修道院) and she began to work for the poor people. She

became an Indian citizen in the following year. In 1950, she set up a religious organization in Calcutta. The organization provided food for the poor people and then she set up hospitals, schools, youth centers, and

homes for the sick and the dying poor. It now has branches in 50 Indian cities and 30 other countries.

     Besides the 1979 Nobel Peace Prize, Mother Teresa has received other awards for her work with the poor people.

     On September 5th, 1997, Mother Teresa passed away, but she will continue to inspire people all over

the world through her lasting present of love and faith. Mother Teresa often reminded the world that she

was a nun (修女), not a social worker, and that prayer and communication with God were at the deepest heart of her every action.
