Jogging has become the most popular individual sport in America. It has become very usual to see people of all ages running along city streets, in parks and along special jogger’s trails that have been built in some cities. Many theories have been advanced to explain the popularity of jogging. The plain truth is that jogging is a cheap, quick, and efficient way to maintain physical fitness.
     The most useful sort of exercise is an exercise that develops the heart, lungs, and circulatory systems. If these systems are fit, the body is ready for almost any sport and for almost any sudden demand made by work or emergencies. One can. train more specifically, but running trains your heart and lungs to deliver oxygen more efficiently to all parts of your body. It is worth noting that this sort of exercise is the only kind that can reduce heart disease, the number one cause of death in America.
     Only one sort of equipment is needed—a good pair of shoes. Physicians advise beginning joggers not to try to run in tennis shoes. No other special equipment is needed. You can jog in any clothing you desire, even your street clothes. Many joggers wear expensive warmup suits, but just as many wear a simple pair of gym shorts and a T-shirt.

选项 A、One that trains the body for weight lifting.
B、One that is both beneficial and inexpensive.
C、One that develops the heart, lungs, and circulatory systems.
D、One that enables a person ready for any sudden demand made by work.

答案 C

解析 细节题。短文中提到The most useful sort of exercise is an exercise that develops the heart,lungs,and circulatory systems.最有用的锻炼方式要能够强化心脏、肺和循环系统功能,故答案为C。A文中没有提及。B是慢跑作为锻炼方式的优点。D在原文中指的是有着健康心脏、肺和血液循环系统的身体,与题干提问不符。
