问题     Studies from 10 nations reveal that the rates of depression among women are twice as high as they are among men. Do women have a biological bent for depression, or are social double standards the major cause?
    Mental health workers have long noticed among the clinically depressed women take up a bigger proportion. Until recently, though, it was unclear whether more women than men were ill or, instead, whether more women sought help. In fact, a mounting collection of studies has confirmed that major depression is twice as common among women as it is among men. "This is one of the most consistent findings we have ever had," says Myrna M. Weissman of Columbia University.
    Scientists searching for explanations are challenged by the fact that a variety of cues prompt depression in different people. Sorting out which factors might have a greater influence on women has not proved easy. Both sexes stand an equal chance of inheriting major depression, so genes are most likely not to blame. Yet hormones and sleep cycles--which differ dramatically between the sexescan alter mood. Also, many workers have proposed that social discrimination might put women under high levels of stress.
    In 1990 an international group examines mood disorders. In the 10 nations reviewed so far, the team has found that among generations reaching maturity after 1945, depression seems to be on the rise and occurs at a younger age. Although overall incidence varies regionally, "everywhere the rates of depression among women are about twice as high as they are among men," Weissman says.
    In contrast, lifetime rates for manic-depressive illness do not differ according to sex or culture. Mark S. George and his colleagues at the National Institute of Mental Health (NIMH) recently studied which regions of the brain have greater blood flow during periods of depression. George found that "the brain activity of the men and women of depression looked very different. " He has since compared feelings of anger, anxiety and happiness, finding no such big a difference.
    Because one in five American women has a history of depression, especially as they often pursue therapy from other sources, sometimes on top of an anti-depressant clinic. Says Leibenluft: "It is remarkable how little work has been done on this subject. "  
The author quotes Leibenluft’s comment in the last paragraph to______.
选项 A、summarize the main idea of the passage
B、recommend an alternative perspective to look at the issue of depression
C、express the author’s pity about the slow improvement on the cure of depression
D、praise the great efforts made by researchers on the subject of depression
答案C
解析 对引用语功能的考查，属于例证题的一种；这种题目的解答要求考生从两个方面人手：(1)对引用语本身意义的理解要正确；(2)一定要结合全文的写作目的来分析引用语在其中发挥的作用和功能。根据这两点，首先，Leibenluft的评论是在讲“在这个领域的研究实在是很有限的”。其次，从全文的角度看，文章中的引用语肯定是在支持或强调作者对主要议题的观点态度。具体到这篇文章，在讨论了对depression的各种研究之后，作者借助Leibenluft的评论表达了自己对这一领域研究滞后的担忧；C对于这一点的分析是到位的，为正确选项。B和D对引语的理解有误差，而A对引语的功能分析不正确。
