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.
According to the government, losing weight .
选项 A、helps ease the burden on the medical care system
B、is the only way to express one’s love for the country
C、shows that people care more about their appearance
D、will benefit the individual more than the country
答案A
解析 根据题干中的the government将本题出处定位到第2段末句。该句提到，政府告诉我们，肥胖对我们的健康有“严重的影响”，而且“给国家卫生系统带来了沉重负担”，所以减肥实际上是我们对国家的义务。由此可知，减肥可以减轻医疗保健系统的负担，故答案为[A]。[B]是针对文中的slimming is practicallyour duty to our country设的干扰项，是对其信息的过度推测；[C]是针对第2段第2句设的干扰项，不是政府对减肥的观点；政府认为肥胖对我们的健康有“严重的影响”，而且“给国家卫生系统带来了沉重负担”，但没说孰重孰轻的问题，故排除[D]。
