阅读理解。 Each nation has many people who help to take care of others. For example, some high school and college students in the U.S.A. often spend many hours as volunteers in the hospitals, orphanages (孤儿院) or rest homes. They read books to the people in these places, or they just visit them and play games with them or listen to their problems. Other young volunteers go and work in the homes of people who are sick or olD. They paint, clean up or repair their houses, do their shopping or mow (割，修剪) their lawns. For boys who no longer have fathers, there is an organization called Big Brothers. College students and some other men take these boys to baseball games or fishing trips and help them get to know things that boys usually learn from their fathers. Each city has a number of clubs where boys and girls can go to play games. Some of these clubs show films or organize short trips to the mountains or some places of interest. Most of these clubs use a lot of high school and college students as volunteers because they are young enough to know the problems and needs of young boys and girls. Volunteers believe that some of the happiest people in the world are those who help to bring happiness to others. ( ) 1. Some college students in America often spend _________ as volunteers.
