Music Used As a Healing Therapy
1 Music has long been used to treat patients suffering from different problems.In 400 BC,its healing
properties were documented by the ancient Greeks.More recently,in both world wars in the last century,
medical workers used music therapy（疗法）with people suffering from trauma（外伤）.Currently, it is used
as a treatment for many diseases,such as cancer,and it has also been used with patients with long-term pain
and learning disabilities.
2 There is growing evidence that music can cause physical changes to the body which can improve our
health.In the Welcome Trust study,which took place over three years at the Chelsea and Westminster hospital in
London,patients were asked to listen to musical performances.As a result,it was found that stress levels
were significantly reduced,recovery times were improved,and fewer drugs were needed.
3 These very positive results are partly due to general well-being（良好的健康状况）.It is already
accepted that when people feel happy and have a positive approach to life,they are more likely to feel better
and recover from disease quickly.Music increases this feeling of joy and adds to the recovery process.
4 However,not all these benefits can be attributed to an increase in general well-being.Music has
other effects which have not yet been understood. According to Professor Robertson,a scientist and musician,
some effects of music are mysterious and are,therefore,being investigated further. It has been suggested that
the sounds and rhythms of music help stimulate the brain and send electrical messages to the muscles.
5 Science,however,demands facts and hard evidence.Many in the medical profession have not yet
recognized the healing benefits of music,since reports have been based mainly on various stories of evi-
dence.These new studies could provide proof to doctors that music is a suitable treatment for many condi-
tions. One day doctors may even"prescribe"（开处方）music,but that could be a long time in the future.
Researchers have found that patients' stress levels decrease when they_________.
A.recover from disease quickly
B.there is not enough hard evidence
C.use their minds actively
D.it improves general well-being
E.listen to musical performances
F.it brings many other benefits

Passage One

Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercises.
