Each nation has many volunteers(志愿者) who help to take care of others. They      books to the people in hospitals or homes for the aged. Sometimes they just visit them and play games with them or listen to their    .

Other young volunteers go and work in the homes of people who are sick or     . They paint, clean up,      their houses or do their shopping.

For boys who no longer have    , there is an organization called Big Brothers. College students and other men take these boys to baseball games or fishing places and help them to get to know things that boys      learn from their fathers.

Each city has a number of clubs     boys and girls can go to play games or learn crafts (工艺). Some of these clubs organize short trips to the mountains, beaches, or other places of interest     . Most of these clubs use high school and college students as volunteers because they are young enough to      the names of boys and girls.

Volunteers believe that the happiest people in the world are those who help to     i happiness to others.
