5.D  细节理解题。根据最后一段,特别是最后一句(common与popular)可知答案。本题易误选C。

B

lt, they do not only look younger and slimmer, but feel better. Because of increased physical fitness, life expectance in the nation has risen to seventy-three years, with fewer people suffering from heart disease, the nation's number one killer.

Jogging ( 慢跑 ), the easiest and cheapest way of improving the body, keeps over 30million people of all ages on the run. For the price of a good pair of running shoes, anyone anywhere can join the race.

Dieting, too, has become a national  pastime. Promoters of diets that eliminate eating one thing or another, such as fats or carbohydrates ( 碳水化合物 ), promise as much as 20- pound weight losses within two weeks. Books describing such amazing diets always head up ( 居……之首 )the best-seller lists because people who are overweight want to lose weight quickly and easily.

Nevertheless, jogging and dieting, carried to extremes, can be harmful. Many confused joggers overdo and finally suffer from ankle and foot damage. Dieting, fortunately, becomes only a temporary means for shedding a few  pounds while the body lose the balanced nutrition ( 营养 )it requires, so most dieters cannot keep on diets. Above all, common sense should be the keystone for any dieting and exercise plan.
