听力原文： Acupuncture is very much a holistic system, taking into account the whole of person. Thus a person is not just a physical entity, but also a mental or emotional entity, even their spiritual side will be included. Acupuncture itself works on an energy system basically. If that energy is blocked or out of balance, you will show certain symptoms. And to stay healthy, diet, exercise and regular life schedule are surely three essential elements. If we live in tune with laws of the universe, we won't get sick. (88)
