答案

参考答案:A

解析: 本题考查Internet方面的基础知识;Internet是电子商务应用的最重要的通信网络基础。它通过各种通信介质和数据通信网,将世界各地的计算机局域网、广域网连接起来。共同遵守传输控制协议/互联网协议(Transfer Control Protocol/Internet Protocol, TCP/IP),构成的世界范围内的网际网(国际互联网)。Internet在企业业务中的应用,可以按照对内和对外分成Intranet Extranet。Intranet指采用Internet技术建立的企业内部网络。Extranet是Internet的另一种应用,Extranet是将Intranet的构建技术应用于企业间系统。
Internet、Intranet Extranet三者的区别和联系在于:Internet是基础,是网络基础和包括Intranet和Extranet在内的各种应用的集合;Intranet强调企业内部各部门的联系,业务范围仅限于企业内;Extranet强调各企业间联系,业务范围包括贸易伙伴、合作对象、零售商、消费者和认证机构。Internet业务范围最大,Extranet次之,Intranet最小。

(46) Surprisingly enough, modern historians have rarely interested themselves in the history of the American South in the period before the South began to become self-consciously and distinctively "Southern"—the decades after 1815. Consequently, the cultural history of Britain’ s North American empire in the seventeenth and eighteenth centuries has been written almost as if the Southern colonies had never existed. The American culture that emerged during the Colonial and Revolutionary eras has been depicted as having been simply an extension of New England Puritan culture. However, Professor Davis has recently argued that the South stood apart from the rest of American society during this early period, following its own unique pattern of cultural development. (47) The case for Southern distinctiveness rests upon two related premises: first, that the cultural similarities among the five Southern colonies were far more impressive than the differences, and second, that what made those colonies alike also made them different from the other colonies. The first, for which Davis offers an enormous amount of evidence, can be accepted without major reservations; the second is far more problematic.

What makes the second premise problematic is the use of the Puritan colonies as a basis for comparison. Quite properly, Davis decries the excessive influence ascribed by historians to the Puritans in the formation of American culture. Yet Davis inadvertently adds weight to such ascriptions by using the Puritans as the standard against which to assess the achievements and contributions of Southern colonials. (48) Throughout, Davis focuses on the important, and undeniable, differences between the Southern and Northern colonies in motives for and patterns of early settlement, in attitudes toward nature and Native Americans, and in the degree of receptivity to metropolitan cultural influences.

(49) However, recent scholarship has ply suggested that those aspects of early New England culture that seem to have been most distinctly Puritan, such as the p religious orientation and the communal impulse, were not even typical of New England as a whole, but were largely confined to the two colonies of America. Thus, what in contrast to the Puritan (Northern) colonies appears to Davis to be peculiarly Southern—acquisitiveness, a p interest in politics and the law, and a tendency to cultivate metropolitan cultural models—was not only more typically English than the cultural patterns exhibited by Puritan Massachusetts and Connecticut, but also almost certainly characteristic of most other early modern British colonies from Barbados north to Rhode Island and New Hampshire. (50) Within the larger framework of American colonial life, then, not the Southern but the Northern colonies appear to have been distinctive, and even they seem to have been rapidly assimilating to the dominant cultural patterns by the last Colonial period.
