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. "  
Which one of the following is true about Myrna M. Weissman’s comment?
选项 A、Women have a biological bent for depression.
B、The chance for women to have a major depression is twice as high as it is for men.
C、Social double standards are the major cause for women’s depression.
D、More women sought help, and this makes it seem like more women suffer from depression.
答案B
解析 细节题；考查区别观点和事实的能力；这是阅读中一种重要的能力，在阅读中，我们要知道哪些是已经证实了的事实，哪些是作者的观点，而哪些是作者引用的观点。A和C属于文章第一段提出的疑问，没有证实，而且不是问题中要求回答的Myma M．Weissman的观点，要排除。D是在第二段出现的，同样只是疑问，未得到证实。对比阅读原文，不难发现，B是对原文信息的正确理解，为正确答案。
