Young people and older people do not agree. 小题1: But in one special programme in New York State, grown-ups and teenagers live together in a friendly way. Each summer 2000 teenagers and 50 grown-ups live together for eight weeks as members of a special work group. Everyone works several hours each day. They do so not just to keep busy but to find meaning and enjoyment in work. Some teenagers work in the woods or on the farms near the villages. 小题2: The grown-ups teach them these skills. There are several free hours each day. Weekends are free, too. During the free hours some of the teenagers learn photo-taking or painting. Others sit around and talk or sing. 小题3: When people live together, rules are necessary. In this program the teenagers make the rules together. If someone breaks a rule, the problem goes before the whole group.
