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. "  
What did the international group find out about mood disorder?
选项 A、The ratio of depression sufferers between women and men is the same in different regions, 1:2 to be exact.
B、After 1945, the majority of those suffering from depression are young people.
C、Region is not a factor to greatly influence the rates of depression among women and men.
D、The total amount of depression sufferers are pretty much the same in different regions.
答案C
解析 细节题；按照题目设计的顺序以及“international gmup”和“mood disorder”这样的定位词回到原文第四段，进行对比阅读可以发现A错误地将男女两性之间患抑郁症的比例搞反了，而且各个地区之间也只是大致相同，并非完全一致，应排除。B项将原文“患抑郁症的人年龄降低”错误地理解为“年轻人成为患抑郁症的主要人群”，属于错误的理解，应排除。D项和原文“各个地区之间的患者总人数有差异”这样的论述相反，很容易排除。
