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.
Which of the following is TRUE about the suggested walking program?
选项 A、Effective walking lies in the gradual increase of speed.
B、The same pace should be kept throughout the walking.
C、One should not stop suddenly while walking fast.
D、One should change one’s walking pattern every 5 minutes.
答案C
解析 判断题。这种判断题可以用排除法解答。从文章所介绍的5个步骤，A 、B 和D 项都不符合文章的内容。只C 项可以与原文中的5个步骤中的最后两个一致。在10分钟的快速步行之后，要有5分钟的中等速度，然后再有5分钟的慢速步行。
