单选题In the early days of the old West in North America, life was difficult. People lived on farms far away from other families. And there were some big problems. For example, how did one family make a house? What did families do to build houses? They asked for help. They invited their friends and neighbors to a work party for a few days. The women cooked together. The men worked on the building. For the children it was like a holiday. Together these people built a house or a barn (谷仓). At another time the family with the new house would help their neighbors. A work party is really cooperation. To cooperate means "to work together". Many people can work together, hen the big job becomes a small job for many workers. Working together can be fun too. Today there isn't much cooperation. People don't work together very much. Some people don't know their neighbors. Why don't we work with other people? It can be fun. Life can become easier too.
