Questions 21 to 25 are based on the following passage.
（附 页）
“ No man is an island， ” wrote the poet John Donne several centuries ago. He
was
acknowledging one of our most distinctive characteristics： the fact that we are social
animals whose behavior and personalities are shaped by the groups to which we belong.
Throughout life， most of our daily activities are performed in the company of
others.
Whether our purpose is working， playing， raising a family，learning， or simply
relaxing，we usually pursue it in groups， even if the group is as small as two or three
people. Out need for human contacts is not merely a practical one； it is a deep
psychological need as well. If people are deprived of the company of others for
prolonged periods， mental breakdown is the usual result. Even the Geneva
Convention（日内瓦公约）， an international agreement that regulates the treatment
of prisoners of war， recognizes this need. It regards solitary（孤独的）
imprisonment for more than thirty day as a cruel form of torture（折磨）。
In its strictest sense，a group is a collection of people interacting together in an
orderly way on the basis of shared expe ctations about one another‘s behavior. As
result of this interaction，members feel a common sense of“belonging.” They
distinguish members from nonmembers and expect certain kinds of behavior from
outsiders.
