单选题In addition to their military role, the foals of the nineteenth century provided numerous other benefits for the American West. Tile establishment of these posts opened new roads and provided for the protection of daring adventurers and expeditions as well as established settlers. Forts also served as bases where enterprising entrepreneurs could bring commerce to the West, providing supplies and refreshments to soldiers as well "as to pioneers. Posts like Fort Laramie provided supplies for wagon trains traveling the natural highways toward new frontiers. Some posts became stations for the pony express; still others, such as Fort Davis, were stagecoach stops for weary travelers. All of these functions, of course, suggest that the contributions of the forts to the civilization and development of the West extended beyond patrol duty. Through the establishment of military posts, yet other contributions were made to the development of western culture. Many posts maintained libraries or reading rooms, and some--for example, Fort Davis--had schools. Post chapels provided a setting for religious services and weddings. Throughout the wilderness, post bands provided entertainment and boosted morale. During the last part of the nineteenth century, to reduce expenses, gardening was encouraged at the forts, thus making experimental agriculture became another activity of the military. The military stationed at the various forts also played a role in civilian life by assisting in maintaining order, and civilian officials often called on the army for protection. Certainly, among other significant contributions the army made to the improvement of the conditions of life was the investigation of the relationships among health, climate, and architecture. From the earliest colonial times throughout the nineteenth century, disease ranked as the foremost problem in defense. It slowed construction of forts and inhibited their military function. Official documents from many regions contained innumerable reports of sickness that virtually incapacitated entire garrisons. In response to the problems, detailed observations of architecture and climate and their relationships to the frequency of the occurrence of various diseases were recorded at various posts across the nation by military surgeons.

单选题Violence in American families takes many forms. One prevalent form that we often overlook is the physical punishment of children. Perhaps 93 percent of all parents beat their children in order to discipline them. Young children receive the most punishment, but studies reveal that about 50 percent of high school seniors report experiencing or being threatened with physical punishment. Punishment of children varies from a light tap to a brutal beating, but historically we have granted parents the right to use physical force against their children. A law passed in 1696, for example, called for the death penally for a child of "'sufficient understanding" over the age of sixteen who cursed or struck a parent or who was "stubborn and rebellious" in refusing to obey a parent. From interviews with 2,143 married couples constituting a cross-section of American families, sociologists estimate that parents kick, punch, or bite some 1.7 million children a year, beat 460,000 to 750,000 more, and attack 46,000 with guns or knives. Physical punishment of children that results in injuries requiring medical treatment is now generally considered to be abusive. Most people do not realize, however, that it is the regular use of "ordinary" physical punishment, and the cultural approval it enjoys, that lays the groundwork for child abuse. According to David Gil, "In most accidents of child abuse the care takers involved are 'normal' individuals exercising their rights of disciplining a child whose behavior they find in need of correction." If one adult were to strike another, most people would regard such behavior as abusive. Most parents use physical punishment in the belief that it will control the aggression in their children and make them obedient. In fact, violence--whether verbal or physical--sets children a poor example. An adult who yells at or slaps a child unwittingly supplies the child with a model for aggression. Studies have found that the frequent use of physical punishment for aggressive acts by a child results in a marked increase in the child's aggression. Perhaps not surprisingly, abusive parents are themselves likely to have been abused when they were children. The pattern of abuse is unwittingly translated from parent to child and thus from generation to generation.
