单选题 The third paragraph mainly tells us that ______.

A、 you will lose more weight running one mile than walking the same distance
B、 you will use more energy walking one mile than running the same distance
C、 for the same distance the faster you walk, the more energy you will use
D、 whether you run one mile or walk the same distance, you use the same energy

【正确答案】 D

【答案解析】本题为段落主旨归纳题。第三段第二句“The troth is that you use the same amount of energy whether you walk or run the mile，since in both cases you are moving the same weight the same distance．”明确指出，无论你是走还是跑一英里，所消耗的能量是一样的，因为你只是在相等的距离内移动了同等重量的身体。
