Conversation Two
对话二

M: Good evening, dear audience.
男：大家晚上好。
I'm glad to continue the topic about music.
很荣幸跟大家继续讨论关于音乐的话题。
It is common knowledge that music can have a powerful effect on our emotions.
众所周知，音乐对我们的情感的作用是难以估量的。
In fact, since the 1930s, music therapists have relied on music to soothe patients and help control pain.
其实，从20世纪90年代起，一些医师就开始利用音乐安抚病人，缓解病人的疼痛。
Now psychologists are confirming that music can also help relieve depression and improve concentration.
如今，心理学家正在求证音乐是否可以帮助人们走出失落情绪，帮助人们集中注意力。
W: That's nice. Do they have any concrete examples?
女：真的是很神奇，可以举一些这方面的例子吗？
M: For instance, in a recent study, 15 surgeons were given some highly stressed math problems to solve.
男：比如说，在近期的一项调查中，15名外科医生被邀请解决一些高难度的数学问题。
They were divided into three groups: one worked in silence; and in another, the surgeons listened to music of their choice on headphones;
他们被分为3组：一组的环境是安安静静；另一组带着耳机听自己选择的音乐；
the third listened to classical music chosen by the researchers.
最后的一组听研究者规定的古典乐。
W: What were the results?
女：结果如何？
M: The results of the study may surprise you.
男：结果会让所有人大吃一惊的。
The doctors who got to choose their music experienced less stress and scored better than the others.
听自己所选择的音乐的一组经测试是压力最小的，最后的分数也略高于其他两组。
W: That is surprising. How to explain this?
女：太不可思议了。这是为什么呢?
M: One possible explanation is that listening to music you like stimulates the Alfa-wave in the brain, increases the heart rate and expands the breathing.
唯一的可能就是你喜欢的音乐会刺激大脑中的阿尔法脑电波，进而影响你的心跳和呼吸频率。
That helps to reduce stress and sharpen concentration.
从而帮助你缓解压力，集中注意力。
W: Is there any other research?
女：还有其他的关于这方面的研究吗？
M: Yes. Another research suggests a second relation between the music and the brain: By examining the students' blood after listening to a variety of classical music collections, the researchers found that some students showed a large increase in a chemical substance-a natural pain reliever-in their blood, which can help soothe the patient.
男：是的。另一项研究表明了音乐与大脑之间存在另一层关系：让学生在听完大量的古典乐之后，对他们的血液进行检查后研究人员发现一些学生体内的某种化学物质飞快增长——这种物质存在于血液之中，是一种天然的有利于缓解病人疼痛的物质。
W: Well, thank you so much for being with us today and having us know about another function of music.
女：哇哦，非常感谢您的到来，还为我们讲解了这么多关于音乐神奇作用的知识。
