It is common knowledge that music can have a powerful effect on our (36) emotions. In fact, since 1930s, music therapists have (37) relied on music to soothe (38) patients and help control pain. Now psychologists are (39) confirming that music can also help (40) relieve depression and improve concentration. For instance, in a recent study, 15 surgeons were given some highly (41)stressed math problems to solve. They were (42) divided into three groups: one worked in silence, and in another, the surgeons listened to music of their choice on headphones; the third listened to (43)classical music chosen by the researchers. The results of the study may surprise you. (44) The doctors who got to choose their music experienced less stress and scored better than the others. 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. That helps to reduce stress and sharpen concentration. Other research suggests a second relation between the music and the brain: (45) by examining the students’ blood after the listening to a variety of classic music collections, there searchers found that some students showed a large increase in endorphin, a natural pain reliever.(46) This supports what music therapists have known for years: Music can help refresh or soothe the patient.

选项

答案 by examining the students’ blood after the listening to a variety of classic music collections

解析 听时要理解句子的逻辑关系,是学生听过各种古典音乐之后,检测他们的血液。这其实是个较长的方式状语,不建议改写。students’ 的复数所有格形式有些同学会写成单数所有格,其实只要看看下一句students的单复数就不会错了。
