Modern holistic medicine is an approach that treats the whole patient, not just the disease. It is a way to maintain good health rather than cure illness . The most important influences on today's holistic medicine are ancient Chinese medicine and Indian Ayurvedic medicine, both of which promoted whole body health. Holistic medicine usually combines diet ,physical exercise and meditation, together with other alternative techniques such as massageand acupuncture. Herbal treatment, a practice of treating illness by using plants, is influenced by the writings of Culpeper as well as Chinese and Ayurvedic medicine. Homeopathyis one of the forms of holistic medicine which is widely practiced in Europe and the USA. Homeopathy began in Germany in the early 1800s, when Samuel Hahnemann described how very tiny dosesof a drug had an effect On his patients. According to Hahnemann, the more the drug was diluted, the stronger its effects . The substance selected would produce similar effects to the disease itself if given in large doses. In the UK homeopathy is regarded as a non-traditional but just about acceptable treatment. Meditation and contemplation have an important role in holistic medicine. They were brought to Europe by Indian teachers who combined Indian Ayurvedic medicine with Western beliefs. Transcendental meditation is one of the best known of these techniques. People repeat words inside their heads to reach a state of deep relaxation. The holistic movement has made many doctors look at the whole patient, not just the disease. Life-style, emotional problems and diet are just some of the factors that can affect a person's health. Holistic medicine emphasizes good diet, exercise and fresh air, all of which contribute to health . Some clinics now offer holistic medicine along with traditional treatments, so that their patients can choose a combination of treatments that suits them. One problem with holistic medicine is that it is difficult for people to be sure a doctor is reliable. To solve this, many countries want alternative doctors to form professional bodies.

If you’re training for a marathon, a proper plan for water intake （摄入） is important. Of course, there’s the risk of dehydration （脱水）. But athletes now know they can also get into trouble by drinking to much . To much water intake can lower levels of sodium （钠） in the blood. The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research.

Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight.

One technique for deciding how much water you need is to get the exact numbers. Runners have to weight themselves before and after a run to determine how much water they’ve lost. If their weight drops by more than 2 percent, they have not drunk enough water.

Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can’t get their rings off, and then they might feel sick. They may not remember where they are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration, the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water.

56．The author of this passage is primarily concerned with 　　　.

　 A．the signs and treatment for dehydration

　 B．the long distance runners who need help

　 C．how to manage water intake during a marathon

　 D．a 28-year-old woman who died after a Boston Marathon

57．Why do runners have to weigh themselves before and after a run?

　 A．They can improve their performance in a run.

　 B．They can learn how much salt there is in the blood.

　 C．They can know the quantity of water they’ve lost during a run.

　 D．They can decide what kind of water they should take during a run.

58．What conclusion can we draw from the passage?
