     Helen Monson has always been interested in helping her community. Her first volunteer experience was

for the American Red Cross when she was in high school. When she was a school teacher, she also found

time to volunteer. One year, she organized a Super Saturday fun day for kids in the community. She also used

to volunteer at the mint festival every year, One summer she served food, another year she organized an art

programme.

     After she retired, she started volunteering to help the old. When her father was older, he was not able to

see as well as he used to, which made her sad because he had always enjoyed reading. She decided it would

be fun to read to elderly people in her community. She also helped one woman write her stories. Ann was

almost 100 years old, and Helen wrote down information about her life when she visited her. She put the

information in a book and got it published. Ann was very excited to share her life story with her children and

grandchildren.

     After a hurricane (飓风) destroyed some southern cities, Helen volunteered again for the American Red

Cross. She prepared food and answered phones in a care centre. She says,"I have always liked the Red Cross

because the organization helps people in need no matter what."

      One day Helen read an article in the newspaper about refugees (难民) who needed to learn English. Now,

she meets once a week with Sahra, a 38-year-old woman from Somalia. Sahra is reading and writing skills.

Helen gave Sahra a camera and asked her to take pictures of her daily life. She developed the pictures, and

then asked Sahra questions about them. In the end, they wrote a book together and used the photos in the

book. This helped Sahra learn many new words about her everyday life.

      Helen says,"The most rewarding (有益的) part of volunteer work is becoming friends with the people

I help, They enrich my life as well as I enrich theirs."
