单选题 Soap operas and situation comedies, though given to distortion, are so derivative of contemporary culture that they are inestimable ______ the attitudes and values of our society in any particular decade.
【正确答案】 C
【答案解析】Soap operas and situation comedies are derivative of contemporary culture: they take their elements from that culture. Therefore, they serve as indices (signs or indications) of what is going on in that culture; they both point to and point up the social attitudes and values they portray.
Note that the soap operas and comedies here cannot be determinants of our society's attitudes and values: they derive from these attitudes and values; they do not determine them.
单选题 Perry's critics in the scientific world ______ that many of the observations he has made during more than a decade of research in Costa Rica have been reported as ______ in popular magazines rather than as carefully documented case studies in technical journals.
【正确答案】 B
【答案解析】The critics charge (make the accusation) that Perry has published only anecdotes of his observations and not detailed analyses. Note that critics would be unlikely to applaud the publication of rumors or apologize for Perry's publication of fabrications or lies. Thus, you can eliminate Choices C and E. Similarly, popular magazines would be unlikely to publish scientific hypotheses or examples of scholarship. You therefore can rule out Choices A and D as well.
