问题      Walking is the easiest and simplest form of exercise. By putting one foot in front of the other, you can start to walk your ways towards a healthier lifestyle. Walking is an easy way to challenge the cardiovascular system (心血管系统), while at the same time building muscles. But to achieve these goals, a little more than a gentle walk around the block is required.
     Walking actually burns as many calories (卡洛里) as running the same distance —— if done in the correct manner and at a reasonable pace (步伐).
     Start with a basic program that you can complete three or four times a week. This should include five main steps:
   ——A beginning warm-up for about 5 minutes.
   ——A little bit faster period of 5 minutes at medium level (中等速度)
   ——A 10-minute “burning” at a high level.
   ——A 5-minute cool down period at a low level again.
   ——A suitable walking pace of around 5 kilometers per hour will burn around 80 calories in 30 minutes.
In order to benefit from walking, we should ______.
选项 A、take it as a planned exercise
B、move as gently as possible
C、do it in a quiet place
D、go as fast as possible
答案A
解析 推理题。本题的问题是：为了从步行中获得好处，我们应该怎么办?文章没有直接回答这个问题。但是，文章第三段详细地介绍了步行锻炼的5个步骤。这5个步骤是很有计划性的。根据第三段推断，我们应该把步行作为一项有计划的锻炼。因此选择A很合适。
