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. [br] In the first 5 minutes of walking, you should walk ______.

选项 A、quickly
B、slowly
C、at top speed
D、at medium pace

答案 B

解析 细节题。根据文章中提到的5个训练步骤,在第一个步骤中是warm—up(热身),即准备阶段。根据常识,热身是慢慢开始的阶段。选择B比较合适。
