问题    Inactivity, fuelled by cars and a sedentary work life, has been dubbed the biggest public health problem of the 21st century, a global pandemic with dramatic impact on people’s wellbeing. The latest reports suggest that around the world it was responsible for 5. 3 million deaths in 2008, which amounts to 1 in 10 people—even more than smoking. Not only does exercise make you fitter, it can also ward off numerous and often unexpected diseases, from heart attacks, to diabetes, some forms of cancer and dementia. There are tentative signs it might even make you cleverer, by boosting cognitive performance and brain function.
   "It’s irrefutable that physical activity and exercise are beneficial for health," says sports scientist Chris Easton. The biggest benefits are seen when people go from being unfit to being moderately fit. At higher fitness levels, you don’t see the same benefits in longevity and disease risk reduction. And although being vigorous is good, you don’t need to go overboard.

选项

答案 由于以车代步和久坐的工作生活方式,愈发突出的不运动现象已被称为21世纪最大的公共健康问题,这是一种严重影响人类健康的全球性流行病。最新报告表明,在2008年,不活动造成了全球530万人的死亡,大约占不活动群体的十分之一,这比吸烟致死的人数都多。运动不仅使你更健康,还可以预防许多突发疾病,比如心脏病、糖尿病、一些类型的癌症和痴呆。有初步迹象表明,运动还能改善认知表现和大脑功能,从而让你变得更聪明。 运动科学家克里斯-伊斯顿说:“体育活动和锻炼对健康有益,这一点是无可辩驳的。”当人们从体质不健康变成体质中等程度健康时,将体会到最大的益处。但是当健康水平进一步提高之后,人们却并不会在长寿和减少疾病风险方面获得相同的好处。同时,虽然高强度运动有益健康,但也不必过量。
