听力原文：W: I've just been reading an article on biotherapy. M: Biotherapy? What's that? W: Well, it's an alternative health system based on the concept that energy is transmitted from one human being to another in order to heal psychologically or physically through regeneration. M: Say that again, in English. W: Well, I'll put it this way. A trained practitioner touches the patient in order to help the healing process. M: Oh, I see. What kinds of things do they cure? W: A variety of conditions and illnesses. According to the article, biotherapy can help people to lose weight, stop headaches, make ageing skin look youthful again, treat depression, even cure cancer. M: Cure cancer? That's pretty ambitious claim. So how does the treatment work? W: It expels negative energy from the organism. M: I don't think that such a confusing explanation would stop me from taking proper medicine if I were un- lucky enough to be ill. W: No, well, that's the beauty of it. You can have conventional medicine together with biotherapy. Fancy going for a bio-energetic check up? M: Well, I'm not so sure about that. Supposing you book an appointment and I come with you first,just to see? (26)
