问题      Some people say that the best way to reduce the body’s mid-section is to do stomach exercise. Many people believe that when specific muscles are exercised, the fatty tissues in the immediate area are "burned up". The truth is that exercise burns fat from all over the body and not from one specific area, no matter what kind of exercise.  Of course, if you reduce the fat throughout your body, you will certainly see results around your waist too.
    It is said that you need to exercise only twice a week in order to keep a sufficient level of physical fitness. Studies conducted by American scientists show that unexercised muscles lose their strength very quickly. After 48 to 72 hours, you must use the muscles again to reestablish the good physical effects. And what does that mean to you? American scientists concluded that while daily exercise is most helpful, every other day, three days a week will keep a sufficient level of physical fitness.
    Is it true that you burn more calories running one mile than walking the same distance? The answer is no. The truth 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. The speed does not matter. Of course, if you run rather than walk for 30 minutes, you will cover more distance, and therefore burn more calories.
    If your breathing doesn’t return to normal within minutes after you finish exercising, you have exercised too much. Five minutes or so after exercising, your breathing should be normal, your heart shouldn’t be beating, and you shouldn’t be exhausted.
What can you learn from this text about the best method to keep fit?
选项 A、Do more running than walking every day of the week.
B、Exercise regularly, every other day of the week.
C、The more exercises you do, the healthier you will be.
D、In order to lose weight, you’d better walk faster.
答案B
解析 本题为综合判断题。作者通过“The truth is that…”和“Studies conducted by American scientists show that…”这类提供可信度的句型，在每一段都摆出了一个正确的观点 (最后一段虽然没有类似的句型，但意思很明显，即不能运动过度)。纵观这些观点，不难断定答案为 B。
