单选题. ①Many cultural anthropologists have come to reject the scientific framework of empiricism that dominated the field until the 1970s and now regard all scientific knowledge as socially constructed. ②They argue that information about cultures during the empiricist era typically came from anthropologists who brought with them a prepackaged set of conscious and unconscious biases. ③Cultural anthropology, according to the post-1970s critique, is unavoidably subjective, and the anthropologist should be explicit in acknowledging that fact. ④Anthropology should stop striving to build a better database about cultural behavior and should turn to developing a more humanistic interpretation of cultures. ⑤The new framework holds that it may be more enlightening to investigate the biases of earlier texts than to continue with empirical methodologies.33. The author implies which of the following about most cultural anthropologists working prior to the 1970s? ______

单选题5. The average temperature of the lobster-rich waters off the coast of Foerkland has been increasing for some years. In warmer water, lobsters grow faster. In particular, lobster larvae take less time to reach the size at which they are no longer vulnerable to predation by young cod, the chief threat to their survival. Consequently, the survival rate of lobster larvae must be going up, and the lobster population in Foerkland's coastal waters is bound to increase. Which of the following, if true, most seriously weakens the argument? ______

单选题. ①Following the United States Civil War (1861-1865), many former slaves in the rural South became sharecroppers (raising a landlord's crop for a share of the profits) or tenant farmers (selling what they raised and paying a share of the profits as rent). ②Most historians tend to depict these African Americans as victims of racism and the farm tenancy system. ③This approach, however, overlooks the role played by such African American rural reformers as Robert Lloyd Smith, founder of the Farmers' Improvement Society of Texas, and Joseph Elward Clayton, the first African American to organize farmers' institutes for the Texas Department of Agriculture. ④Both men advocated comfortable homes and better schools for African Americans; both attributed poverty and illiteracy to causes other than racism, such as insect damage to crops; and both worked to keep Black farmers on the land, although Smith opposed farm tenancy. ⑤Both were also accused by their contemporaries of downplaying the devastating impact of the farm tenancy system on Black farmers and of accommodating racism. ⑥While the extent of these reformers' influence requires more study, clearly their organizations provided a voice for African American farmers seeking to improve their positions in the agrarian South.8. The passage is primarily concerned with ______

单选题. ①A critical consensus has emerged that Mary McCarthy will be remembered primarily as an essayist rather than as a novelist. ②But despite her formidable gifts as a polemical and discursive writer, and for all her reputation as an intellectual who sacrificed feeling to intelligence, what powers McCarthy's best essays are her fictional rather than strictly intellectual gifts. ③She makes her points by telling stories or by ways of description, arresting images, and subtle characterization. ④And for all her exacting sense of fact, McCarthy's greatest contribution was to blur the distinctions between different kinds of prose writing, to show how fiction could be opened up to the thinking mind and how essays could profit from the techniques of fiction.8.
