单选题The beginning of what was to become the United States was characterized by inconsistencies in the values and behavior of its population, inconsistencies that were reflected by population, inconsistencies that were reflected by its spokesmen, who took conflicting stances in many areas, but on the subject of race, the conflicts were particularly vivid. The idea that the Caucasian race and European civilization were superior was well entrenched in the culture of the colonists at the very time that the "egalitarian" republic was founded. Voluminous historical evidence indicates that, in the mind of the average colonist, the African was a heathen, he was black, and he was different in crucial philosophical ways. As time progressed, he was also increasingly captive, adding to the conception of deviance. The African, therefore, could be justifiaby (and even philanthropically) treated as property according to the reasoning of slavetraders and slaveholders. Although slaves were treated as objects, bountiful evidence suggests that they did not view themselves similarly. There are many published autobiographies of slaves. African- American scholars are beginning to know enough about West African culture to appreciate the existential climate in which the early captives were raised and which therefore could not be totally destroyed by the enslavement experience. This was a climate that defined individuality in collective terms. Individuals were members of a tribe, within which they had prescribed roles determined by the history of their family within the tribe. Individuals were inherently a part of the natural elements on which they depended, and they were actively related to those tribal members who once lived and to those not yet born. The colonial plantation system which was established and into which Africans were thrust did virtually eliminate tribal affiliations. Individuals were separated from kin. Interrelation- ships among kin kept together were often transient because of sales. A new identification with those slaves working and living together in a given place could satisfy what was undoubtedly a natural tendency to be a member of a group. New family units became the most important attachments of individual slaves. Thus, as the system of slavery was gradually institutionalized, West African affiliation tendencies adapted to it. This exceedingly complex dual influence is still reflected in black community life, and the double consciousness of black Americans is the major characteristic of African-American mentality. Du Bois articulated this divided consciousness as follows: The history of the American Negro is the history of this strife--this longing to attain self-conscious manhood, to merge his double self into a better and truer self. In this merging, he wishes neither of the older selves to be best. Several black political movements have looked upon this duality as destructively conflictual and have variously urged its reconciliation. Thus, the integrationists and the black nationalists, to be crudely general, have both been concerned with resolving the conflict, but in opposite directions.

单选题There are so many new books about dying that there are now special shelves set aside for them in bookshops, along with the health-diet and home-repair paperbacks. Some of them are so 21 with detailed information and step-by-step instructions for performing the function, that you'd think this was a new sort of 22 which all of us are now required to learn. The strongest impression the casual reader gets is that proper dying has become an extraordinary, 23 an exotic experience, something only the specially trained can do. 24 , you could be led to believe that we are the only 25 capable of being aware of death, and that when the rest of nature is experiencing the life cycle and dying, one generation after 26 , it is a different kind of process, done automatically and trivially, or more "natural", as we say. An elm in our backyard 27 the blight (枯萎病) this summer and dropped stone dead, leafless, almost overnight. One weekend 28 was a normal-looking elm, maybe a little bare in spots but 29 alarming, and the next weekend it was gone, passed over, departed, taken. Taken is right, for the tree surgeon came by yesterday with his 30 of young helpers and their cherry picker, and took it down branch by branch and carted it off in the back of a red truck, everyone 31 . The dying 32 a field mouse, at the jaws of an amiable household cat, is a spectacle I have beheld many times. It 33 to make me wince.
