单选题 Passage Four At the fall 2001 Social Science History Association convention in Chicago, the Crime and Justice network sponsored a forum on the history of gun ownership, gun use, and gun violence in the United States. Our purpose was to consider how social science historians might contribute to the public debate over gun control and gun rights. To date, we have had little impact on that debate. It has been dominated by mainstream social scientists and historians, especially scholars such as Gary Kleck, John Lott, and Michael Bellesiles, whose work, despite profound flaws, is politically congenial to either opponents or proponents of gun control. Kleck and Mark Gertz, for instance, argue on the basis of their widely cited survey that gun owners prevent numerous crimes each year in the United States by using firearms to defend themselves and their property. If their survey respondents are to be believed, American gun owners shot 100, 000 criminals in 1994 in self-defense--a preposterous number. Lott claims on the basis of his statistical analysis of recent crime rates that laws allowing private individuals to carry concealed firearms deter murders, rapes, and robberies, because criminals are afraid to attack potentially armed victims. However, he biases his results by confining his analysis to the year between 1977 and 1992, when violent crime rates had peaked and varied little from year to year. He reports only regression models that support his thesis and neglects to mention that each of those models find a positive relationship between violent crime and real income, and an inverse relationship between violent crime and unemployment. Contrary to Kleck and Lott, Bellesiles insists that guns and America's "gun culture" are responsible for America's high rates of murder. In Bellesiles's opinion, relatively few Americans owned guns before the 1850s or know how to use, maintain, or repair them. As a result, he says, guns contributed little to the homicide rate, especially among white, which was low everywhere, even in the South and on the frontier, where historians once assume guns and murder went hand in hand. According to Bellesiles, these patterns changed dramatically after the Mexican War and especially after the Civil War, when gun ownership became widespread and cultural changes encouraged the use of handguns to command respect and resolve personal and political disputes. The result was an unprecedented wave of gun-related homicides that never truly abated. To this day, the United States has the highest homicide rate of any industrial democracy. Bellesiles's low estimates of gun ownership in early America conflict, however, with those of every historian who has previously studied the subject and have thus far proven irreproducible. Every homicide statistic he presents is either misleading or wrong. Given the influence of KJeck, Lott, Beliesiles, and other partisan scholars on the debate over gun control and gun rights, we felt a need to pull together what social science historians have learned to date about the history of gun ownership and gun violence in America, and to consider what research methods and projects might increase our knowledge in the near future.

单选题 Biologically, there is only one quality which distinguishes us from animals: the ability to laugh. In a universe which appears to be utterly devoid of humor, we enjoy this supreme luxury. And it is a luxury, for unlike any other bodily process, laughter does not seem serve a biologically useful purpose. In a divided world, a laughter is a unifying force. Human begins oppose each other on a great many issues. Nations may disagree about systems of government and human relations may be plagued by ideological factions and political camps, but we all share the ability to laugh. And laughter, in turn, depends on the most complex and subtle of all-human qualities: a sense of humor. Certain comic stereotypes have a universal appeal. This can best be seen from the world-wide popularity of Charlie Chaplain's early films. The little man at odds with society never fails to amuse no matter which country we come from. As that great commentator on human affairs, Dr. Samuel Johnson, once remarked, "Men have been wise in very different modes; but they have always laughed in the same way." A sense of humor may take various forms and laughter may he anything from refined tinkle to an earthquaking roar, but the effect is always the same. Humor helps us to maintain a correct sense of values. It is the one quality which political fanatics appear to lack. If we can see the funny side, we never make the mistake of taking ourselves too seriously. We are always reminded that tragedy is not really far removed from comedy, so we never get a lop-sided view of things. This is one of the chief functions of satire and irony. Human pain and suffering are so grim; we hover so often on the brink of war, political realities are usually enough to plunge us into total despair. In such circumstances, cartoons and satirical accounts of somber political events redress the balance. They take the wind out of pompous and arrogant politicians who have lost their sense of proportion. They enable us to see that many of our most profound actions are merely comic or absurd. We laugh when a great satirist like Swift writes about wars in Gulliver's Travels. The Lilliputians and their neighbors attack each other because they can't agree which end to break an egg. We laugh because we are meant to laugh; but we are meant to weep too. It is no wonder that in totalitarian regimes any satire against the Establishment is wholly banned. It is too powerful weapon to be allowed to flourish. The sense of humor must be singled out as man's most important quality because it is associated with laughter. And laughter, in turn, is associated with happiness. Courage, determination, initiative--these are qualities we share with other forms of life. But the sense of humor is uniquely human. If happiness is one of the great goals of life, then it is the sense of humor that provides the key.
