    If Americans have been slow to realize the disturbing state of our collective health, we have—as individuals and as a nation—at last begun to wake up. Take our long and almost always unhappy battle with weight. In recent years, the scale has been telling not just a distressing tale, but also a truly shocking one. Between 1980 and 2004, the prevalence of obesity in the US doubled among adults, surging to 72 million, or one-third of people ages 20 and older. Worse, the percentage of overweight or obese kids rose to 17%. If all those numbers could be cut by even a third, the ripple effect would in turn slash rates of hypertension (高血压), heart disease, diabetes, cancer, joint damage and more, not to mention the myriad costs associated with fighting these illnesses.
    And indeed, there may be flickers (M8R) of hope. From 2005 to 2006, the percentage of women and children who are overweight appeared to stabilize, while the rate for men increased only slightly. "That’s good, but it’s not as if it’s flattening at a good level," notes Cynthia Ogden, an epidemiologist at the National Center for Health statistics, part of the Centers for Disease Control and Prevention. Still, the improvement is no accident, and for women and particularly children, it can be traced to aggressive nutrition and exercise messages promoted in schools, hospitals, community groups and churches—precisely the kind of low cost, high-impact measures health experts love.
    Similar preventive methods may help cap soaring cholesterol levels. Since the late 1960s,the average serum cholesterol level of adults has continued to drop, from a high of 220 mg/dL down to 199 mg/dL in 2006. That cut the percentage of Americans with high cholesterol (胆固醇) to 17% , precisely the goal set by the Healthy People 2010 targets—and it was reached four years ahead of schedule. Routine blood tests for low-and high-density lipoproteins (脂肪蛋白) , or bad and good cholesterol—as well as the use of cholesterol—lowering medications when needed—have played a major role in powering those improvements.
    The same principles of education, prevention and early treatment can apply to mental health as well.One in 20 Americans over age 12 reported feeling depressed in 2006, with non-Hispanic blacks making up the largest percentage. Although 80% of Americans admitted that their symptoms interfered with their ability to work, only 29% had contacted a mental health professional. Recent improvements in screening at primary-care facilities, one of the goals set by Healthy People 2010, may help address this problem: while 62% of primary care facilities provided treatment for mental disorders in 2000. 74% do so now.
Which of the following is true according to Para. 1 ?
选项 A、Americans are always concerned about their health.
B、There is a big increase in the number of obese adults in America from 1980 to 2004.
C、There is no increase in the percentage of overweight kids from 1980 to 2004.
D、It is hard to say whether the joint damage is related to the obesity.
答案B
解析 推理判断题。第一段第四句表示1980到2004年问，成年人的肥胖率翻倍。故B正确。第一段第一句说明美国人一直对糟糕的健康状况不注意，直到现在才开始形成关注，故排除A；第一段第五句中的rose to表示儿童的肥胖率也有增加，故排除C；第一段最后一句的ripple effect意为“连锁反应”，可见其两者是有关系的，故排除D。
