     It's not uncommon in America for a person to belong to some kind of volunteer group. Donating

one's time and services is very much a part of the American way of life. Most charitable activities are

organized by churches and groups around the nation and even encouraged by the government. The

helping hand is extended to the poor, the homeless and the disabled. Some people work to teach

youngsters how to read. others open up soup kitchens to feed the homeless. Volunteers also take care

of the disabled by making reading tapes for the blind and working in orphanages (孤儿院) to help

children without parents.

     High school students are often encouraged to become volunteers and many school club activities

center around volunteer services. Students may work with disabled children during a summer program,

or participate in a club activity which helps to bring meal to senior citizens who are shut-ins. With their

sense of idealism (理想主义) students are often eager to donate their spare time. They see such

activities as a way of becoming involved in the community and the adult-world. Social action for them

becomes as important as their academic studies.

     In a like manner, throughout the year, fund raising drives are also conducted by schools and

community groups to raise money for a worthy cause. They may respond to a recent earthquake in a

foreign country, a flood somewhere within their own, or another natural disaster which has left people

destitute and homeless. They may organize drives to collect food, clothing and medicines to serve an

immediate need. Today even the Halloween custom of 'trick or treat' has become an occasion to collect

money for a charitable cause.

     This call to help those less fortunate than themselves arises from the humble origins of the American

nation. Those immigrants who were poor and downtrodden (受压迫的) became dependent on the

kindness of their neighbors to make a new life for themselves.

     American volunteers work throughout the world in less developed countries. They volunteer by

serving as a champion of goodwill both at home and abroad, which no doubt enriches both his life and

those whom he serves.
