<篇章結構>第31至34題為題組 While Dr. Weinstein， a surgeon at Dartmouth College， was trying to lift a heavy box， he twisted his back. The pain was agonizing. The surgeon could not sit， and when he lay down he could barely get up. So he decided to go out for a run. He took an aspirin， iced the injured area， and off he went. When he returned， he felt “pretty good.” 31 When people have sprained a muscle or tendon， they are usually advised not to go right back to exercising until the pain goes away. But Dr. Weinstein says that approach is outdated and counterproductive. In fact， when active people consult him， he usually tells them to just keep exercising. (A) For example， an injured runner might end up cycling and swimming instead of running. (B) Over time， researchers have come to realize the importance of exercising when injured. (C) Many suggest that most patients can continue with the sport they love. (D) This seems to run counter to the common practice.
