单选题 Bernard Bailyn has recently reinterpreted the early history of the United States by applying new social research findings on the experiences of European migrants. In his reinterpretation, migration becomes the organizing principle for rewriting the history of preindustrial North America. His approach rests on four separate propositions. The first of these asserts that residents of early modern England moved regularly about their countryside; migrating to the New World was simply a natural spillover. Although at first the colonies held little positive attraction for the English-they would rather have stayed home-by the 18th century people increasingly migrated to America because they regarded it as the land of opportunity. Secondly, Bailyn holds that, contrary to the notion that used to flourish in America history textbooks, there was never a typical New World community. For example, the economic and demographic character of early New England towns varied considerably. Bailyn's third proposition suggest two general patterns prevailing among the many thousands of migrants: one group came as indentured servants, another came to acquire land. Surprisingly, Bailyn suggests that those who recruited indentured servants were the driving forces of transatlantic migration. These colonial entrepreneurs helped determine the social character of people who came to preindustrial North America. At first, thousands of unskilled laborers were recruited; by the 1730's, however, American employers demanded skilled artisans. Finally, Bailyn argues that the colonies were a half-civilized hinterland of the European culture system. He is undoubtedly correct to insist that the colonies were part of an Anglo-American empire. But to divide the empire into English core and colonial periphery, as Bailyn does, devalues the achievements of colonial culture. It is true, as Bailyn claims, that high culture in the colonies never matched that in England. But what of seventeenth-century New England, where the settlers created effective laws, built a distinguished university, and published books? Bailyn might respond that New England was exceptional. However, the ideas and institutions developed by New England Puritans had powerful effects on North American culture. Although Bailyn goes on to apply his approach to some thousands of indentured servants who migrated just prior to the revolution, he fails to link their experience with the political development of the United States. Evidence presented in his work suggests how we might make such a connection. These indentured servants were treated as slaves for the period during which they had sold their time to American employers. It is not surprising that as soon as they served their time they passed up good wages in the cities and headed west to ensure their personal independence by acquiring land. Thus, it is in the west that a peculiarly American political culture began, among colonists who were suspicious of authority and intensely anti-aristocratic.

单选题Many Americans regard the jury system as a concrete expression of crucial democratic values, including the principles that all citizens who meet minimal qualifications of age and literacy are equally competent to serve on juries; that jurors should be selected randomly from a representative cross section of the community; that no citizen should be denied the right to serve on a jury on account of race, religion, sex, or national origin; that defendants are entitled to trial by their peers; and that verdicts should represent the conscience of the community and not just the letter of the taw. The jury is also said to be the best surviving example of direct rather than representative democracy. In a direct democracy, citizens take turns governing themselves, rather than electing representatives to govern for them. But as recently as in 1968, jury selection procedures conflicted with these democratic ideals. In some states, for example, jury duty was limited to persons of supposedly superior intelligence, education, and moral character. Although the Supreme Court of the United States had prohibited intentional racial discrimination in jury selection as early as the 1880 case of Strauder v. West Virginia, the practice of selecting so-called elite or blue-ribbon juries provided a convenient way around this and other antidiscrimination laws. The system also failed to regularly include women on juries until the mid-20th century. Although women first served on state juries in Utah in 1898, it was not until the 1940s that a majority of states made women eligible for jury duty. Even then several states automatically exempted women from jury duty unless they personally asked to have their names included on the jury list. This practice was justified by the claim that women were needed at home, and it kept juries unrepresentative of women through the 1960s. In 1968, the Congress of the United States passed the Jury Selection and Service Act, ushering in a new era of democratic reforms for the jury. This law abolished special educational requirements for federal jurors and required them to be selected at random from a cross section of the entire community. In the landmark 1975 decision Taylor v. Louisiana, the Supreme Court extended the requirement that juries be representative of all parts of the community to the state level. The Taylor decision also declared sex discrimination in jury selection to be unconstitutional and ordered states to use the same procedures for selecting male and female jurors.
