单选题With the debt crisis and the weakening economy fresh on their minds, most Americans have probably concluded that government, as a rule, cannot manage money responsibly. But it can. Just look at Montana. For six years it has been one of the only states in America with a budget surplus: this year it is a record of $433 million, proportionally equivalent to a federal surplus of $858 billion. Thus we"ve been able to cut taxes, invest in education and infrastructure and keep essential services intact. We recently got our first bond rating upgrade in 26 years. How do we accomplish what most states and the federal government cannot? I like to say we run government like a ranch. In ranching, you either pinch pennies or go bankrupt. We do the same in government. For one thing, we challenge every expense. If it isn"t absolutely necessary, we eliminate it. Little things added up: we renegotiated state contracts, cut our energy consumption by 20 percent, auctioned off state vehicles and canceled building projects and computer upgrades. The federal budget contains thousands of similar line items. A government serious about tightening its belt would eliminate them all. But we don"t just cut costs. Like good ranchers, we also leave some grain in the barn in case of drought. When times were good, we stored away cash in a special savings account. The account proved to be a big help in getting us through the recession in solid financial shape. I cannot recall the federal government"s ever banking surplus funds in a protected account, even during the surplus-laden 1990s. If Washington ever digs out of the current hole and runs a cash balance, Congress should likewise put some grain in the barn. And even as we"ve cut costs and stored away money, we"ve followed another ranching principle: treat your ranch hands with respect. Like other states, we"ve had to freeze employee pay and reduce the work force. But as in any good organization, many of the best solutions for cutting costs come from state employees. Some look at payroll as a burden; we look at it as human capital, and we work hard to keep up morale in tough times. So when we cut the state payroll, I cut my own salary. Sadly, many politicians, especially in Washington, seem to take advantage of the opportunity to trash government workers. This is just cheap and ugly scapegoating. More to the point, it does nothing to produce bottom-line results. Finally, we don"t spend money until we"ve found the lowest price. When the real estate market softened, we told commercial landlords who rented space to the state that if we didn"t see rent reductions, we"d move to cheaper premises when our leases were up. There are savings to be found everywhere in government. Now that federal spending is the country"s top issue, Washington should try doing what any rancher or family household does.

单选题Some recent historians have argued that life in the British colonies in America from approximately 1763 to 1789 was marked by internal conflicts among colonists. Inheritors of some of the viewpoints of early twentieth-century Progressive historians such as Beard and Becker, these recent historians have put forward arguments that deserve evaluation. The kind of conflict most emphasized by these historians is class conflict. Yet with the Revolutionary War dominating these years, how does one distinguish class conflict within that larger conflict? Certainly not by the side a person supported. Although many of these historians have accepted the earlier assumption that Loyalists represented an upper class, new evidence indicates that Loyalists, like rebels, were drawn from all socioeconomic classes.(It is nonetheless probably true that a larger percentage of the well-to-do joined the Loyalists than joined the rebels.)Looking at the rebel side, we find little evidence for the contention that lower-class rebels were in conflict with upper-class rebels. Indeed, the war effort against Britain tended to suppress class conflicts. Where it did not, the disputing rebels of one or another class usually became Loyalists. Loyalism thus operated as a safety valve to remove socioeconomic discontent that existed among the rebels. Disputes occurred, of course, among those who remained on the rebel side, but the extraordinary social mobility of eighteenth-century American society(with the obvious exception of slaves)usually prevented such disputes from hardening along class lines. Social structure was in fact so fluid—though recent statistics suggest a narrowing of economic opportunity as the latter half of the century progressed—that to talk about social classes at all requires the use of loose economic categories such as rich, poor, and middle class, or eighteenth-century designations like "the better sort. " Despite these vague categories, one should not claim unequivocally that hostility between recognizable classes cannot be legitimately observed. Outside of New York, however, there were very few instances of openly expressed class antagonism. Having said this, however, one must add that there is much evidence to support the further claim of recent historians that sectional conflicts were common between 1763 and 1789. The "Paxton Boys" incident and the Regulator movement are representative examples of the widespread, and justified, discontent of western settlers against colonial or state governments dominated by eastern interests. Although undertones of class conflict existed beneath such hostility, the opposition was primarily geographical. Sectional conflict—which also existed between North and South—deserves further investigation. In summary, historians must be careful about the kind of conflict they emphasize in eighteenth-century America. Yet those who stress the achievement of a general consensus among the colonists cannot fully understand that consensus without understanding the conflicts that had to be overcome or repressed in order to reach it.

单选题There are many theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the assumption that drama evolved from ritual. The argument for this view goes as follows. In the beginning, human beings viewed the natural forces of the world, even the seasonal changes, as unpredictable, and they sought through various means, to control these unknown and feared powers. Those measures which appeared to bring the desired results were then retained and repeated until they hardened into fixed rituals. Eventually stories arose which explained or veiled the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later called myths, persisted and provided material for art and drama. Those who believed that drama evolved out of ritual also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used. Furthermore, a suitable site had to be provided for performances, and when the entire community did not participate, a clear division was usually made between the "acting area" and the "auditorium". In addition, there were performers, and, since considerable importance was attached to avoiding mistakes in the enactment of rites, religious leaders usually assumed that task. Wearing masks and costumes, they often impersonated other people, animals, or super natural beings, and mimed the desired effect-success in hunt or battle, the coming rain, the revival of the Sun—as an actor might. Eventually such dramatic representations were separated from religious activities. Another theory traces the theater"s origin from the human interest in storytelling. According to this view, tales(about the hunt, war, or other feats)are gradually elaborated, at first through the use of impersonation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely related theory traces theater to those dances that are primarily rhythmical and gymnastic or that are imitations of animal movements and sounds.
