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.

Music can treat patients partly because________.
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

答案：D

解析：

从文章第一段中的几个表示时间先后的词“In 400BC, More recently, Currently”可知，本段主要讲的是音乐疗法的历史。故选C。
该段主要讲述音乐能使身体发生积极的变化从而改善健康。故选E。
该段主要讲述音乐可以增进身体健康。故选B。
该段主要讲述音乐对身体有利不仅体现在可以增进健康，还有其他一些影响是末被发现的。接着讲Robertson教授认为音乐的一些未被发现的影响是神秘的。故选D。
由文章第二段第二、三句话可知，研究发现听了音乐演出的病人压力减少了，健康恢复时间缩短了，用药量也减少了。故选E。
由文章第三段可知，音乐能治疗疾病部分原因是它能增进身体健康。故选D。
由文章第三段第二句话可知，普遍认为当人们心情愉悦、生活态度积极向上时，那么人的精神就会好，从疾病中康复的速度也会快。故选A。
由文章第五段前两句话可知，科学需要建立在事实和确凿的证据上。很多医生还不认同音乐可以治病，因为关于音乐能治病的报道基于各种各样的故事。故选B。第4部分：阅读理解第一篇本文主要讲述了芭蕾舞的发展史以及对芭蕾舞的发展和进步起到重要作用的人物。

第7题：

Operations which left patients __________and in need of long periods of discovery time now leave them feeling relaxed and comfortable.

A.unhealthy
B.exhausted
C.fearful
D.upset

答案：B

解析：

考查形容词辨析。句意为“以前，病人手术后__________，需要很长时间才能恢复，现在手术的病人却感到既轻松又舒适”。unhealthy意为“不健康的”，exhausted意为“精疲力竭的”，fearful意为“担心的，可怕的”，upset意为“苦恼的，不适的”。病人不需要很长的时间用来恢复，说明手术后应该不是精疲力尽，故选B。

第8题：

C ) reduce drug dosages for their patients

D) prolong the needless suffering of the patients

正确答案：D
答案：D
[试题分析] 文章细节事实题。
[详细解答] 题干要求考生回答乔治?安纳斯认为在以下哪一种情况下，医生应该受到制裁。安纳斯所关注的是病人病痛能否得到有效处理，为解决这个问题他认为医生可以采取任何必要的措施和手段。在最后一段，他明确指出，对病人不必要和可预见的痛苦漠不关心的医生应该受到惩罚。因此D选项“延长病人不必要的痛苦”是正确答案。A选项“不能胜任管理病人的工作”太宽泛，文中具体指的是病人痛苦的死亡可被认为是医生不能胜任管理的表现。文章第五段提到，安纳斯认为只要医生开的药物是用于合法的医疗目的，就没有违法，所以B选项“给病人的药物超过所需”和c选项“减少给病人的药物剂量”可排除。

题干意为“研究人员已经发现，当病人收听音乐表演的时候，他们的压力水平会下降。”文章第二段最后一句指出，病人的压力水平明显减低，恢复的时间缩短，需要的药物减少。E项listen to musical performances（收听音乐表演）与原句意思相符，故选E。
