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.
A 2004 study from the Harvard School of Public Health shows that______.

选项 A、it is impossible to be both fat and fit
B、doing exercises makes people healthy
C、the thin tend to be physically active
D、taking more exercise means longer life

答案A

解析 根据题干中的A 2004 study from the Harvard School of PublicHealth将本题出处定位到第4段首句。该句提到“……并不是这样”。很显然,该句是对上句问题”是否可能身体虽胖但依然健康一一不仅仅是健康到足以做运动,而且健康到能和比你瘦很多的人一样活得一样长?”的回答,故[A]“不可能即肥胖又健康”为答案。该段的末句提到,这个数据不支持‘只要积极锻炼身体,就不用担心体重’的理论,[B]“运动使人健康”与此矛盾;[C]“瘦人往往会积极锻炼身体”在文中未提到;文中未提到运动和寿命之间的必然关系,故排除[D]“做运动越多就意味着活得越长”。
