【答案解析】[听力原文]
Western doctors are beginning to understand what traditional healers have always known, that the body and the mind are inseparable. Until recently, modern urban physicians heal the body, psychiatrist the mind, and priests the soul. However, the medical world is now paying more attention to holistic medicine, which is an approach based on the belief that people"s state of mind can make them sick or speed their recovery from sickness. Several studies show that the effectiveness of a certain drug often depends on the patient"s expectations of it. For example, in one study, psychiatrists and a major hospital tried to see how patients could be made calm. They divided them into two groups. One group was given a drug while the other group received a harmless substance instead of medicine without their knowledge. Surprisingly, more patients in the second group showed the desired effect than those in the first group. In study after study, there"s a positive reaction in almost one-third of the patients taking harmless substances. How was this possible? How can such a substance have an effect on the body? Evidence from a 1997 study at the University of California shows that several patients who received such substances were able to produce their own natural drug, that is, as they took the substance their brains released natural chemicals that act like a drug. Scientists theorized that the amount of these chemicals released by a person"s brain quite possibly indicates how much faith the person has in his or her doctor.
