汉译英;但是正如其他许多已经发生过的事情一样，当他们最终结婚后，发现最憧憬的生活变得再实际不过了。他们非但没有分担各自原先的责任---正如那些学生们所说"一半一半"，相反却发现生活的重担加倍了。这使得我们那两个结婚的朋友时常觉得沮丧;他们突然发现自己并没有过着天堂般的生活而是仍实实在在地生活在地球上，而且成为了新规则和新约束的奴隶。生活并没有比以前更自由、更幸福，因为他们要去承担新的责任。既然成立了一个新的家庭，那就无论如何也要尽一点家庭的义务。他们深情地回想起订婚的那段时光，曾经如此地渴望拥有彼此而忘掉这个世界，然而现在最深切的感受却是自己仍是这个世界的一份子。

Bernard Bailyn has recentlyreinterpretedthe early historyof the United States by applyingnew socialresearchfindingson theexperiencesofEuropean migrants.Inhisreinterpretation,migrationbecomes the organizingprinciplefor rewritingthe historyofpreindustrial North America. His approach rests on four separate propositions.The firstof these asserts that residentsof early modern England moved regularlyabouttheir countryside; migrating to the New World was simply a natural spillover. Although atfirstthe colonies held littlepositiveattractionfor the English D they would rather havestayed home D by the eighteenth century people increasingly migrated to America becausethey regarded it as the land of opportunity. Secondly, Bailyn holds that, contrary to thenotion that used to flourish in America history textbooks, there was never a typical NewWorld community.For example, the economic and demographiccharacterof early New Englandtowns varied considerably.Bailyn's third proposition suggest two general patterns prevailing among the manythousands of migrants:one group came as indenturedservants,another came to acquire land.Surprisingly,Bailyn suggests that those who recruitedindentured servants were the drivingforces of transatlanticmigration.These colonialentrepreneurshelped determine the socialcharacterof people who came to preindustrialNorth America.At first,thousands ofunskilled laborers were recruited; by the 1730's, however, American employers demandedskilled artisans.Finally, Bailyn argues that the colonies were a half-civilized hinterland of theEuropean culture system. He is undoubtedly correct to insist that the colonies were partof an Anglo-American empire. But to divide the empire into English core and colonialperiphery, as Bailyn does, devalues the achievements of colonial culture. It is true, asBailyn claims, that high culture in the colonies never matched that in England. But whatof seventeenth-century New England, where the settlers created effective laws, built adistinguished university, and published books Bailyn might respond that New England wasexceptional. However, the ideas and institutions developed by New England Puritans hadpowerful effects on North American culture.Although Bailyn goes on to apply his approach to some thousands of indenturedservantswho migrated just prior to the revolution, he fails to link their experience with thepolitical development of the United States. Evidence presented in his work suggests howwe might make such a connection. These indentured servants were treated as slaves for theperiod during which they had sold their time to American employers. It is not surprisingthat as soon as they served their time they passed up good wages in the cities and headedwest to ensure theirpersonal independence by acquiringland. Thus, it is in the west thata peculiarly American political culture began, among colonists who were suspicious ofauthority and intensely anti-aristocratic.

[A] A larger percentage of migrants to colonial North America came as indenturedservants than as free agents interested in acquiring land.

As Gilbert White，Darwin ， and others observed long ago， all species appear to have theinnate capacity to increase their numbers from generation to generation. The task forecologistsis to untangle the environmentaand biologicalfactorsthat hold this intrinsiccapacity for population growth in check over the long run. The great variety of dynamicbehaviorsexhibitedby differentpopulationmakes thistaskmore difficult：sompopulations remain roughly constant from year to year; others exhibit regular cycles ofabundance and scarcity; still others vary wildly， with outbreaks and crashes that arein some cases plainly correlated with the weather， and in other cases not.To impose some order on this kaleidoscopeof patterns ， one school of thought proposesdividing populations into two groups. These ecologists posit that the relatively steadypopulations havedensity-dependent growth parameters; that is， rates ofbirth ， death ，and migrationwhich depend strongly on population density. The highly varying populationshave density-independent growth parameters， with vital rates buffeted by environmentalevents ;these rates fluctuate in a way that is wholly independent of population density.This dichotomy has its uses， but it can cause problems if taken too literally. Forone thing ， no population can be driven entirely by density-independent factors all thetime. No matter how severely or unpredictably birth， death ， and migration rates may befluctuatingaround theirlong-termaverages ， ifthere were no density-dependenteffects ，the populationwould ， in the long run ， eitherincrease or decrease without bound (barringa miracle by which gains and losses canceled exactly)。 Put another way， it may be thaton average 99 percent of all deaths in a populationarise from density-independentcauses ，and only one percent from factors varying with density.The factorsmaking up the one percentmay seem unimportant， and their cause may be correspondingly hard to determine. Yet，whether recognized or not， they will usually determine the long-term average populationdensity.In order to understand the nature of theecologist ’s investigation， we may think ofthe density-dependent effectson growth parameters as the signal ecologists are trying toisolateand interpret， one that tends to make the population increase from relativelylowvalues or decrease from relatively high ones， while the density-independent effects actto produce noise in the populationdynamics.For populationsthatremain relativelyconstant ， or that oscillate around repeated cycles， the signal can be fairly easilycharacterized and its effects described， even though the causative biological mechanismmay remain unknown. For irregularly fluctuating populations， we are likely to have toofew observations to have any hope of extracting the signal from the overwhelming noise.But it now seems clear that all populationsare regulatedby a mixture of density-dependentand density-independent effects in varying proportions.
