问题     Just as you can be slim and inactive, it’s possible to be overweight and active. But which is better for your health?
    Two months ago, an awful lot of us decided it was time to get off our ever-spreading backsides and do some exercise. This new year’s resolution wasn’t just about vanity (虚荣), oh no. The government tells us that obesity (肥胖) has a "severe impact" on our health, and places a "significant burden on the NHS (the National Health Service)", so slimming is practically our duty to our country.
    If the fat is already melting away, then lucky you. But what if the exercise doesn’t seem to be working? What if you can now run a kilometre in a minute and a half, yet your weight has hardly changed? Are you a lost cause? Or is it possible to be both fat and fit — not just fit enough to exercise, but fit enough to live as long as someone a lot lighter?
    Not according to a 2004 study from the Harvard School of Public Health, which looked at 115,000 nurses aged between 30 and 55. Compared with women who were both thin and active (ie, who reported taking 150 minutes or more of exercise a week) researchers found that obese but active women had a mortality rate (mortality rate is the number of deaths during a particular period of time among a particular type or group of people) that was 91% higher. Though far better than the inactive obese (142% higher), they were still worse off than the inactive lean (5% higher). "This data does not support the theory that if you are physically active, you don’t have to worry about your weight," was the opinion of Frank Hu, who led the study.
    A similar picture emerged in 2008 after Harvard-affiliated researchers examined 39,000 women with an average age of 54. Next to active women of normal weight, the active but overweight were 54% more likely to develop heart disease, while the active but obese were in 87% greater danger. "Even high quantities of physical activity are unlikely to fully reverse the risk of heart disease in overweight and obese women without concurrent (同时发生的) weight loss," the authors concluded.
What can be concluded from the passage?
选项 A、Being slim and inactive is better than being overweight and active.
B、Physical activity is especially important to those who are overweight.
C、Obese people can do nothing to reduce their high risk of heart disease.
D、The government’s focus on obesity is not grounded in solid data.
答案A
解析 文中第4段第2、3句提到，研究人员发现肥胖而积极运动的女性死亡率……仍然比不运动但清瘦的人(死亡率高5％)糟糕。由此可知，清瘦而不运动要比肥胖而又运动好，故答案为[A]。该研究也同时回答了首段的核心问题。第4段论述了运动、肥胖和死亡率的关系，第5段论述了运动、体重和心脏病之间的关系，两个研究表明，运动不能使胖人的死亡率或得心脏病的几率下降，故推断不出运动对胖人的重要性，故排除[B]；从末段末句可以推出，大量运动再加上减肥的话可以减少胖人息心脏病的风险，故排除[C]；文中未提到政府对肥胖的关注是否是基于确凿的数据之上，故排除[D]。
